Does not fit correctly in PCI slot

Connector edge is shorter than motherboard socket. product has 58 pins per side vice 62. also has two notches vice one notch. noticed differences from picture on Zonet web site, but sticker on product says it is a ZUH2215V. can I install it anyway? will notch in board keep edge connector aligned to the correct mating pins on motherboard? has anyone seen a board like this with only 58 pins for PCI 2.2 compliant board?

P6TD fusible resitor blown near memory P0207?


What a minute hold the phone here!

Those are Ferrite Iron Choke Coils.

The 'little round cans' with the Red(?) edge on top, are Solid Polymer Capacitors, going around the processor socket.

Those are Ferrite Choke Coils going around the top side of the processor socket, immediately near the copper heat pipe fins. (Black/Square shaped top, rectangular shaped body)

The choke coils, and solid capacitors are part of the Motherboard Voltage Regulator Circuit. These particular ones are for the processor.

The ones down by the Ram Memory slots are also in the Motherboard Voltage Regulator Circuit.

May be for the Ram Memory slots, but easily could also be for the expansion slots, too. (PCI-E x16, PCI-E x1, PCI, etc)

Here is more info on the Motherboard Voltage Regulator Circuit,

http://www.hardwaresecrets.com/article/616

So; Are you using the correct voltage ram memory, or have you installed 'performance stuff', and had to change voltage in BIOS Setup?

More importantly,
1) Are you running a graphics card?
2) More than one?
3) Have the proper amount of power, (Wattage and 12 Volt power rail/s)
4) Proper power cables from Power Supply?

4) Same thing for the motherboard;
IF, you are using a Processor that requires a LOT of Wattage, and you are using a graphics card; are you plugging in an 8-pin EPS +12 Volt power cable into the motherboard?

The 8-pin EPS +12 Volt power cable connector, is called an EATX12V power cable connector by Asus. It's up at the top edge of the motherboard, above the top left corner of the processor socket.

Called EATX12V to keep people from confusing it with this power cable,

http://www.hardwaresecrets.com/article/616

They are NOT the same;
EATX12V, or EPS +12 Volt power cable; has FOUR Yellow wires.
A Yellow insulated wire is a 12 Volt wire. Black wires are Ground wires.

An 8-pin PCI Express power cable has THREE Yellow wires, and FIVE Black wires.

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

BOTH, a 4-pin ATX +12 Volt power cable, and an 8-pin EPS +12 Volt power cable; are power for the PROCESSOR.

Quad-Core, or a processor that uses this much power? 8-pin EPS +12 Volt power cable.

The MAXIMUM amount of Wattage a PCI-Express x16 slot can deliver is 75 Watts.
EACH 6-pin PCI Express power cable is capable of delivering 75 Watts.
Total of 150 Watts available for a graphics card.

An 8-pin PCI Express power cable is capable of delivering 150 Watts by itself.

Point?
Use the correct power cable IF needed for the graphics card, and the correct number of them if two are required.

Also; IF you did not have the correct power cables; AND used a power adapter cable, USE all of the required 4-pin Peripheral power cables needed, for that power adapter cable.

For example;
I have noted those who did not have TWO 4-pin Peripheral power cables, required for a 6-pin PCI Express adapter power cable.
Just one was available, and just one was used.........

!O_O!
Nope!
This will result in;
1) PCI Express x16 slot contact pins - Burn
2) Gold plated contact pins on bottom of PCI-Express graphics card -Burn
3) 6-pin PCI Express power cable connection on graphics card - Burns
4) Contact pins in connector for 6-pin PCI Express power cable - Burns

That to me could also result in damage to electronic components, in the Motherboard Voltage Regulator Circuit;

Hence -> Ferrite Iron Choke Coils

Awaiting your response,

M3A770DE 4 pin


Due to the 'large expanse' of information you posted I can barely contain myself.

1) 4-pin ATX +12 Volt power cable, that plugs into the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Note that this power cable has TWO Yellow 12 Volt wires.

Back in the day there was no additional power cable needed, for the motherboard.
When the Intel Pentium 4 came out, the 4-pin ATX +12 Volt power cable came out also.

Power for the Processor.

More, and more powerful hardware components for the motherboard, (Processor and graphics card), required more power to the motherboard.

The 6-pin PCI Express power cable was brought out,

http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress

This power cable was used to connect directly to a graphics card, and provide power to it.

Note that this power cable has THREE Yellow 12 Volt wires.
It can carry up to 75 Watts of power.

Still wasn't enough power TO the motherboard, and TO the graphics card, with the new hardware component technology being brought out.

The 8-pin EPS +12 Volt power cable was brought out,

http://www.playtool.com/pages/psuconnectors/connectors.html#eps8

Note that this power cable has FOUR Yellow 12 Volt wires.
Is capable of providing up to 150 Watts.

A PCI Express x16 slot is capable of providing 75 Watts.

Note the shape of the sockets in the connector.
Now compare to an 8-pin PCI Express power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress8

DO NOT confuse the 8-pin EPS +12 Volt power cable, with the 8-pin PCI Express power cable.
They are NOT the same.

The 8-pin EPS +12 Volt power cable's connector on the motherboard, is at the top left corner of the Processor socket, and close to the outside edge of the motherboard.

(With motherboard installed in computer case)

You can use the motherboard with just a 4-pin ATX +12 Volt power cable.

Look at the LOCK on the side of the 8-pin EPS +12 Volt power cable's connector.

With that Lock AWAY from you, or on the opposite side of the connector, a 4-pin ATX +12 Volt power cable plugs in on the RIGHT side.

If you have a powerful graphics card installed in your
PCI Express x16 -> slot/S, you had definitely better use a Power Supply that has an 8-pin EPS +12 Volt power cable.

This is a 4-pin standard Peripheral power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

Misnomered as a 'Molex' power cable.
{ Molex was the first to design and produce this style of power cable CONNECTOR. The name stuck. Kind of like calling an open-end wrench a Crescent wrench }

IF you use an adapter power cable; Use TWO 4-pin standard Peripheral power cables!!
You need those Yellow 12 Volt wires.

What will happen if you do not use two?

1) The PCI Express x16 slot/s will burn.

2) The gold plated contact pins on the PCI Express graphics card, or cards, will burn.

3) If the graphics card, or graphics cards, require a power cable connected to them;
A) The connections on the graphics card for the power cable will burn.

B) The power cable connector will burn.

Other than that the only other 4-pin references on the motherboard, that I can see, is the optical drive's 4-pin audio cable connector on the motherboard, (CD1), and the CPU (Processor) Fan 4-pin connector on the motherboard.

For additional questions, or if the above is not what you seek, post in a Comment.

Mcp61sm-am motherboard manuel needed


Ya know Acer owns Gateway now,

http://support.gateway.com/s//MOTHERBD/Shared/4006233R/4006233Rnv.shtml

A) Power Supply to motherboard cabling;

http://www.ebay.com/itm/ECS-MCP61SM-AM-V-1-0A-SOCKET-AM2-AMD-MOTHERBOARD-uATX-/290606277901

Scroll down to the motherboard top view photo.

Product Views > Hardware Details

1) 24-pin ATX main power cable. (S - Main Power Connector)

This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

[Note color of connectors does NOT matter ]

Note the Lock on the side of the main power cable's connector, and the matching Tab on the motherboard connector. When properly plugged in, the hooked end of the Lock will be over the Tab, on the motherboard connector.

In the photo of the motherboard shown on the Ebay link, this connector is on the Right side of the motherboard, next to the blue IDE (PATA) connector.

2) 4-pin ATX +12 Volt power cable; (F - Auxiliary 12V ATX Connector)

General example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

In the motherboard photo; Small square 4-socket hole connector, to the Bottom/Left corner of the Processor socket.

This power cable's connector also has a Lock, and the motherboard connector has a Tab.

That's all the power cables that go to the motherboard.

B) With 2 SATA headers (Connectors) on the motherboard, and one IDE (PATA) connector, it suggests to me that this motherboard is set up to use a SATA harddrive.

This is a general example of a SATA power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Note that it has 15 contact pins, and between it, and the SATA data cable connector, it is the larger of the two.
There is a Lock tab on the connector that you depress, to install, or remove the cable.

You can use a SATA optical drive (CD/DVD drive), or an IDE (PATA) optical drive.
An IDE (PATA) optical drive uses a standard 4-pin Peripheral power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

[ Misnomered as a 'Molex' power cable. Molex was the first to make the power cable's connector. Name stuck, kind of like calling an open-end wrench a Crescent wrench ]

A SATA data cable is used for the SATA harddrive. The connector end that goes to the Harddrive, is usually a 90 degree bent elbow.
The straight end plugs into the motherboard,

General example of a SATA data cable, and it's corresponding connector on the motherboard,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

Note the L-shape in the inside of the SATA data cable's connector, and the L-shape on the motherboard connector. They line up.
The SATA power cable also has this L-shape.

In Hardware Details click on -> Q - SATA Connectors
The Bottom one, or one closest to the outside edge of the motherboard, is SATA1.

Although it isn't marked on the motherboard, or at least not visible in this photo, SATA 4 is. Look at the top where a SATA 4 connector would be.
The SATA harddrive should be plugged into the SATA1 header.
(Connector)

HOWEVER, the beauty of SATA is that it does NOT matter, which SATA header on the motherboard, you plug the SATA harddrive into.

BIOS will find it.

(Supposed to be SATA harddrive to SATA1, and a SATA optical drive to SATA2)
In the motherboard photo on Ebay, they are Orange in color, and under the blue IDE (PATA) connector.

C) Going from Hardware Details and the Ebay motherboard photo;

B - CPU Fan 1 Connector, is where the Processor fan plugs in.
In the motherboard photo, there are 7 cylindrical Electrolytic Capacitors in a row, to the left of the processor socket.

This connector is located immediately above the top capacitor, near the outside edge of the motherboard. (Brown in color)

E - Floppy Disk Connector, is above the white 24-pin ATX main power cable's connector, and the blue IDE (PATA) connector. It is Yellowish in color. (34 pins)

G - System Fan Connector, is white in color, has 3 contact pins, and is located under the white, square 4-pin ATX +12 Volt power cable connector. This is where the computer case fan plugs in.

I - PCI Express x16 Connector, is Orange in color, and below the processor socket. It has PCI Express silkscreened on the motherboard immediately below it.
This where a graphics card, and ONLY a graphics card, is installed.

J - PCI Express x1 Connector, is white in color, and immediately below the orange PCI Express x16 connector.
This is NOT used for a graphics card.

Whatever you can use in a PCI slot, except a graphics card, can be used in this slot; -> Provided it is a PCI Express x1 card.
(Ethernet Card, Sound Card, etc)

L - CD-in Connector is where the audio cable from the Main (Primary) optical drive goes to.
Ya got me on this one. I know it's located real close to the Realtek audio chipset, and I think that is to the left of the orange PCI Express x16 slot.

M - Front Audio Connector, is where the front audio (Sound) ports, of the Front Panel connect to.
Green in color, and located under the bottom white long PCI slot, and near the outside edge of the motherboard.

N - Clear CMOS Jumper is self explanatory. It is located under the finned Heatsink, (Looks like a meat tenderizer), of the Southbridge chip.
(Which is located under the Ram Memory slots)

O - USB Connectors are Yellow in color, and located under the finned Heatsink of the Southbridge chip, and towards the outside edge of the motherboard. (Or also located under the Ram Memory slots)

P - Front Panel Connector, is located at the Bottom/Right corner of the motherboard, close to the 'Buzzer'. (Buzzer is used for BIOS Beep Codes) PANEL1

4 pins on the Left side, 5 pins on the Right side.
The pins on the Left side are numbered EVEN.
The pins on the Right side are numbered ODD.

Starting on the Bottom of the Left side going Up;
Pins 2, 4, 6, 8, and 10.

Starting on the Bottom of the Right side going Up;
Pins 1, 3, 5, and 7

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light)
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.

B) Pins 5 and 7 are for a Reset switch. IF a Reset switch is used.

C) Pin 9 is Not Connected. Used by the factory.

D) Pins 2 and 4 are for the Power On LED. (Light)
Pin 2 is for the Positive ( + ) wire.

How to install Pci-e 16x in a pci slot


Do not put a PCI-e card in a PCI slot. It will not fit and the card won't work. The PCI card has 58 or 60 pins on each side with the slot (62 pins would be present if not for the key notches for alignment). PCIe 16x cards have 32 pins.

There are adapters to put a PCI card in a PCIe 1x slot (will fit any PCIe slot) or a PCIe1x card in a PCI slot. See http://www.amfeltec.com/index.php for a sample of the adapters. For the PCIe 16x cards, you need a new motherboard.

If you are placing a PCI-e 16x card in a PCIe 16x slot or a PCI card in a PCI slot, then open the side of your case. Locate the matching slot (remove the current card) or an empty slot depending on your motherboard. Depending on the case, you may need to remove a screw to remove the old card. Wiggle the card straight up to remove it. If you are putting in a new card, you will need to remove the cover from the slot. (For some larger PCIe 16x cards, you need to remove the adjacent slot cover as well.) Some covers just pull straight up or pry a lever up and then pull; for others, you will need to use a screwdriver to break the cover out. Make sure there is sufficient room near the slot for the card. (You may need to move other cards around.)

Then line up the card so that the back of the card will fit into the opening and the contacts on the bottom of the card are above the center of the slot. Firmly press the card down into the slot without changing the alignment. You may need to wiggle it (press down on the back and front, alternatingly). Then make sure the card is fully seated. Attach the addtional power cord from your power supply, if needed for a PCIe 16x card.

Close your case. Then if this is a new video card, turn on the computer and enter the BIOS (press F1, F2, F10, Esc depending on the machine). Disable the on-board video. Then reboot the computer and load the drivers you need for the card.

I hope this helps.

Hi, Is Asus ATI Radeon HD6450 Silence 1GB DDR3 VGA/DVI/HDMI Low Profile PCI-Express Video Card capable for my Compaq HP Presario SR2020NX? -thanks a lot.


You mean will the Asus ATI Radeon HD6450 with 1GB of graphics memory, work in a Compaq Presario SR2020NX Desktop PC?

Yes.

The Compaq Presario SR2020NX Desktop PC has a PCI-Express x16 expansion slot.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00757470&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3245048

{Motherboard illustration and photo are towards the bottom of the page}

Look at the specifications.
Scroll down to the heading - Expansion slots.

Three PCI. (PCI expansion slots)

One PCI Express x16 graphics.

NOTE*
Looking at the motherboard illustration, it is Wrong.
Shows - PCIEX1 (PCI E X1)
According to the specifications it is a PCIEX16 expansion slot. (PCI-E x16)

A PCI-Express x1 slot has 36 contact pins. 18 on each side.

In comparison a PCI slot {White} has 124 contact pins. 62 on each side.

Looking at the photo of the supposed PCI-E x1 slot they show, the black PCI-Ex1 slot is longer than the white PCI slots.

It is a PCI-Express x16 slot with 164 pins. 82 on each side.



The Asus ATI Radeon HD6450 uses a PCI-Express x16 expansion slot.

So you know the graphics card will fit. Low-profile to boot.

Power requirement:
The Compaq Presario SR2020NX desktop computer comes with a 300 Watt power supply.
(Although in actuality it's more like 70 percent of the maximum rated wattage. 210 Watts)

Enough power for the computer, and the graphics card.
ATI graphics cards do not use as much power as a comparable Nvidia graphics card.

Concerned that the Asus graphics card uses DDR3 graphics ram memory, and the Presario SR2020NX uses DDR2 Sdram ram memory?

Don't be. The graphics cards graphics memory runs independent of the computer's ram memory.

Can i replace the audio chip?


No, at least I wouldn't recommend it.

Chip and Chipset are slang terms for I.C.
Integrated Circuit.

http://en.wikipedia.org/wiki/Integrated_circuit

The mounting of an audio chip uses a style of surface mount.
BGA.
Ball Grid Array.

http://en.wikipedia.org/wiki/Ball_Grid_Array

Referring back to the older Processor's, they used pins on the bottom.
These pins mated up to socket holes in the processor socket.

With a BGA surface mount there are no pins.
Solder balls take the place of the pins.
The motherboard has matching copper pads for mating the solder balls.

The chip is set correctly in place on top of the copper pads, and the chip is then properly heated until the solder balls melt, and solder the chip to the copper pads.

It would be Much easier to just install a Sound Card.
The Sound Card can be installed in any available PCI or PCI-E x1 slot.

What are the parts of the motherboard?


1) Let's start with the 'Brain'. The Processor:

The Processor sits in a Processor socket on the motherboard.
The socket will match the particular Processor that is used.

On the older computers, the different Processor manufacturers often used the same type of processor socket, for their Processors.
As computer technology evolved, the different processor manufacturers started using a processor socket that only matched their particular Processors.

Now only AMD processors will fit in an AMD processor socket.
Same for Intel, and the same for VIA.

2) Ram Memory:
Ram Memory comes in a Module. Often referred to as 'Stick'
The Ram Memory modules sit down in a ram Slot.
Correct computer speak is Bank. Each slot is a Bank.

Ram Memory modules are specific in the number of contact pins on the bottom of them.
(Gold plated contact pins)

SDR Sdram, often just referred to as Sdram, has 168 contact pins. 82 on each side.
(Single Data Rate Sdram {Sychronous Dynamic Random Access Memory)
The bottom of the ram memory module also has Two Locating Notches.

DDR Sdram has 184 contact pins. 92 on each side. One Locating Notch

DDR2 Sdram has 240 contact pins. 120 on each side. One Locating Notch

DDR3 Sdram has 240 contact pins. 120 on each side. The Locating notch is in a different place than the DDR2 Sdram ram module.


3) Expansion slots:

An add-in card is a small circuit board. This can refer to a,

A) Graphics Card, (Graphics Adapter Card, or also known as Video Adapter Card)
B) A Modem Card (Again, > adapter has been dropped off)
C) A Sound Card (Audio) {Adapter has been dropped off)
D) Ethernet Card
Or a number of other technologies used.

The add-in card is inserted into the appropriate expansion slot.


4) Motherboard Chipset:
Chip and Chipset are slang terms for I.C.
Integrated Circuit.

The motherboard chipset consists of the Northbridge chip, and the Southbridge chip.

[NOTE*
This does not apply to new technology used for the Intel Core i3. i5, i7, and i9 processors ]

The Northbridge chip handles the faster capabilities of the computer

The Northbridge chip supports;
A) What Processor is used.
B) What Ram Memory is used
C) High-speed graphics.

{High-speed graphics is considered to be AGP, or PCI-Express. Not a graphics card inserted into a PCI slot, nor Integrated Graphics }

The Southbridge chip supports the slower capabilities of the computer.

D) Any add-in card inserted into a PCI slot
E) Integrated Graphics
F) IDE (PATA) and SATA harddrives
G) USB ports
H) Data coming from the Super I/O chip, and it's associated hardware connected to it.

(The Northbridge chip is connected to the Southbridge chip by the Front Side Bus. {FSB}
Think of the FSB as an 'Information Highway'.

Data {Information} is transferred to the Northbridge from the Southbridge, and to the Southbridge from the Northbridge, via the FSB.

The Southbridge chip is connected to the Super I/O chip by the Internal Bus.

Motherboard Diagram;

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

(CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short. It Does Not refer to the computer as a unit)

This shows a typical motherboard, and refers to the different parts of it,

http://en.wikipedia.org/wiki/File:Acer_E360_Socket_939_motherboard_by_Foxconn.svg

I invite you to type the following terms in the search box on Wikipedia, and learn more about the parts of the Motherboard, and the technology of the different parts of the motherboard, and the associated hardware that goes on the motherboard,

1) CPU socket
2) Bus (computing)
3) Expansion Card

Look for numbers at the very end of the memory sockets for numbers WIHTOUT a letter in front, 184 is DDR1, 240 is ddr2. About 1/2 the boards do not have these numbers.

You can also try the business card trick using a regular US size business card, or make a piece of paper exactly 2 inches (51mm) wide.

With good lighting, look into the memory sockets. You'll see a 'nub' close to the middle of the socket. UNPLUG the computer, don't just turn it off. Turn the business card so the shorter edge goes into the shorter side of the memory slot, with one end all the way against the end, like it was a piece of memory.
Count how many pins are left between the edge of the card and the nub.
4 pins left means DDR, 9 pins left means DDR2.

DDR-400 will work in almost any ddr board, and ddr2-800 (aka PC-6400) will work in almost any ddr2 board.

Strangely enough, those also tend to be the cheapest speeds as well as the highest standard speeds.

Where does the pci plug in?


PCI expansion cards are installed inside the computer case. Read the instructions for the card to determine if software needs to be installed prior to hardware, or vice-versa. Shut off the PC and remove the fasteners on the rear that hold the left side panel in place.

The motherboard will be visible, along with connectors, plugs, wires and fans. There should be a couple of long, narrow off white slots on the motherboard. These slots line up with removable metal strips on the back of the case. If these long, narrow slots are all in use, installing another PCI card can not be done until an existing card is removed. This is not recomended - unless replacing a defective card with a new one. If there is an unused slot, a new card may be installed - after removing the metal strip inside - at back of the case. Save the screw.

Align the card. If it does not align, it is not the correct type for this computer. Firmly - yet gently - press the edge of the card into the slot. Do not force the card. Once installed, secure the card in place with the screw removed earlier.

Reassemble and power up as per instructions with the card.
