I have an old acre desk top that I use purely for music. It has 2 512 DDR 3 ram sticks that is replaced with 2 1gb sticks and it won't boot with them so I put the original ones back in and no go. I ha


Sounds like you static shocked a stick. You should always be grounded when handling components. Try putting in only 2@512m sticks at a time until computer boots to find the bad stick. Also,when it boots,check memory size at bootup.Make sure it sees 1G

Ihow to boot up and get display and set bios on msi motherboard g41m-e43


Add one item at a time.
First memory, then graphics card.

Plus you cleared CMOS Error Codes, and set the BIOS Setup parameters back to the factory default settings.

Guess what the default graphics setting is for an MSI G41ME43 motherboard?

Yep, AGP.

http://www.msi.com/product/mb/G41M-E43.html

[Wow, I like MFlash, and the solid Polymer capacitors.
Live BIOS Update 5, and Easy OC Switch.

However if the motherboard fails, I'll bet the Integrated Circuit, (I.C., or 'chipset'), that controls APS, is the first electronic component to go.

I would also watch OC'ing. Has to be done in incremental steps. Automatic feature or not. A 20 percent boost is A LOT.
Hardware components have as tendency to heat up.
Watch it as this lowers the 'life expectancy' of the chips.
Heat - 'Kills' ]

Motherboard chipset:
Northbridge is an Intel 82G43. Southbridge chip is an Intel 82801GB part number. (ICH7) You can't see them as they are under Heatsinks.

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Core_2_chipsets

Ram Memory:
Two ram memory slots for Dual Inline Memory Modules on the motherboard. (DIMM)

A) UNBUFFERED
B) 1.5 Volt (DC)
C) DDR3 Sdram at either 800MegaHertz, or 1066MHz.

[ This puzzled me. DDR3 Sdram at 800MegaHertz?
Why would anyone want to use DDR3 Sdram at 800MegaHertz?
Seems to me going backwards.

Faster frequency rates.
Low end for DDR3? 1066MHz.
High end for DDR2? 800MHz.

DDR3 is faster in comparison to DDR2 per se, because of the prefetch buffer. 8 burst deep compared to DDR2's 4 burst deep.
(Or DDR's 2 burst deep)

Not because of the CAS Latency, though.
DDR3 has a much higher CL, than compared to DDR2.

(Average CL for DDR3 at 1066MHz = 7-7-7-20
DDR2 = 5-5-5-15. Note* -> A-V-E-R-A-G-E. )

When using DDR3 Sdram at least use 1066MHz, IMHO
The maximum ram memory frequency rate, that your motherboard will support ]

So what manufacturer of ram memory is it, and what is the manufacturer code of the ram memory module/s? ('Stick')

JEDEC sets the standards for Ram Memory.
Voltage standard for DDR3 Sdram ram memory is 1.5 Volts (DC)
So the factory default setting is 1.5 Volts, for the motherboard.

However your motherboard supports SPD.
(Serial Presence Detect,

http://en.wikipedia.org/wiki/Serial_presence_detect )

Point of the above?
If you are trying to use high-performance ram memory; say one needing a slightly higher voltage, and/or has lower CL ratings; then the SPD on the motherboard may make automatic adjustments.
(Adjustments to the parameters in your BIOS Setup)

May take 2 to 3 'Cold Boots', though.
(Turn the computer all the way off. Wait 1 minute. Turn the computer back on = Cold Boot)

I order for SPD to work, BOTH the motherboard, AND the ram memory, have to have SPD feature.
If the ram memory is too low in quality, (Read cheap), it may not have SPD.

Means you have to go into BIOS Setup, and set the ram memory parameters, manually.

[ Delete key to enter BIOS Setup.
Main BIOS Setup menu > Cell Menu > Memory Z > Advance DRAM configuration >
1) DRAM Timing Mode
2) CAS Latency
3) tRCD
4) tRP
5) tRAS
6) tRTP

Don't forget you have to SAVE changes, or it will be as if you have done nothing at all.

If a mistake is made;
Go back to BIOS Setup, and in the Main menu, use the Down Arrow key to arrive at Load Fail-Safe Defaults. IF -> OK is 'highlighted' (Black surround) press the Enter key. If not, use the Right Arrow key, or Left Arrow key, and highlight OK ]

The ram memory also has to be UNBUFFERED.

Unbuffered ram memory is the opposite of Registered ram memory.
Registered ram memory is more stable, usually one clock slower, and more expensive, than compared to unbuffered ram memory.

Registered ram memory is usually used in SERVER computers.

(A Server computer may look at information 2 or 3 times, before it acts on it. It needs to be C-O-R-R-E-C-T for a server computer )

"Cleared the board i believe"

Turned the computer off? Unplugged from power? Pressed the Power ON button in, and held it in for a count of 10 seconds? Then let go of the Power On button, then performed the entire procedure again, 2 more times?

{Clears CMOS Error Codes, and resets BIOS Setup back to the factory default settings}

You MAY have cleared the motherboard. It's what I use, and have recommended for years on the 'net. Doesn't mean it always works, though. Sometimes you just have to go into BIOS Setup, and set the parameters back to the factory default settings.

(For you? Load Fail-Safe Defaults )

A) Won't boot:
Because the ram memory is the wrong one, (Or ones); OR, the ram memory is high performance, and BIOS and SPD hasn't recognized it yet.

Remove the graphics card.(Computer unplugged from power. Anti-Static Precautions FOLLOWED!)
Remove the ram memory.

Reinstall the old ram memory, and plug the monitor into the VGA port, in the I/O area on the back of the computer tower.

Just get the computer working again. After about 10 minutes of fooling around on the computer, ('net?), turn the computer off.
Install the new 2GB.

(IF, just one ram memory module, be SURE to put it in Slot 1.
{DIMM 1} The ram memory slot closest to the Processor )

Leave the computer case open. You may be going back in pretty soon. (Graphics card)
WAIT 1 minute, then turn the computer on.

Joy?
If no joy shut the computer down. (Press the Power On button in, and hold it in for a count of 10 seconds)

WAIT 1 minute, turn the computer on.
If it doesn't work this time, you may wish to try it again.
Sometimes takes 2 to 3 times, before the high-performance ram memory is recognized.

You can also go into BIOS Setup, as mentioned, and physically set the ram parameters.
After 3 times I would give up however, and send the ram memory back. Wrong one/s.

If you get the new Ram Memory working, Cool!
If not remove it, and use the old ram memory.
Might as well get the computer going with the new graphics card, while you wait on the proper ram memory to arrive.

Did you plug the monitor into the graphics card?
Sometimes we computer geeks get in a wee bit of a hurry, when we get shiny new parts. Make sure the monitor cable is plugged into the graphics card.

There is another tiny thing; DRIVERS
If you did not use the Installation Disk (CD) first, THEN physically installed the graphics card, you are Wrong.

OR downloaded the drivers from EVGA.

What happens if you physically install a graphics card, THEN come back and install the drivers?
Most of the time a Driver Conflict.

Windows: "Which drivers do I use? These or THESE?"

Also sets BIOS Setup to the correct graphics aperture.

With the computer set back to the factory default settings, and the monitor plugged into the VGA port on the motherboard, you can get Windows running, and install, or download AND install, the Drivers.

ONCE the drivers, (And user interface -> Nvidia Control Panel), have been installed, you can then physically install the graphics card.

[Again; If you download the drivers, do NOT forget you have to go to where they are downloaded, and DOUBLE-click on the file, then use the Installation Wizard. (Or double-click on the .exe file)
INSTALL them! ]

Drivers installed, close all windows, go back to your desktop screen.
Turn the computer off. Unplug from power. FOLLOW Anti-Static Precautions. Physically install the graphics card. Plug the monitor into the graphics card. Plug the computer back into power. WAIT 1 minute, turn the computer on.

2.6 volt ram


For the Compaq Presario SR1920NX?

http://h10025.www1.hp.com/ewfrf/wc/product?cc=us&lc=en&dlc=en&product=3184154

Product information > Product specifications > Compaq Presario SR1920NX Desktop PC Product Specifications,

Memory:
PC3200
That is DDR Sdram, that operates at a maximum frequency rate of 400MegaHertz. (400MHz)

JEDEC voltage standards for DDR Sdram is 2.5 Volts,

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

(Specification standards
Read down )

JEDEC,

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

The motherboard, may not have SPD features. (Serial Presence Detect)
Do not know if the ram memory does, either.
SPD,

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

Sometimes it takes turning the computer off, wait 1 minute, then turn it back on. Sometimes it takes 2 to 3 times of this.
If BIOS doesn't set the voltage up 1/10th of a volt, you may have to do it manually in your BIOS Setup (Utility)

Where did you get DDR Sdram that uses 2.6 Volts, and is it high-performance ram memory?
Post the manufacturer name of the ram memory, and it's manufacturer code, in a Comment.

[The normal factory default setting for the ram memory voltage, is 2.5 Volts. I would see if BIOS Setup will allow bumping the voltage up, before I would EVEN think of a BIOS upgrade ]

Acer Aspire M3400 Desktop PC. Memory Upgrade Issue


please check the memory timing settings. if your mixing up ram they may not have the same memory timings and require you to go either higher or to the supported settings that either memory can use. for example if corsair runs at 8-8-8-14 and kingston runs at 10-10-10-16 then you will need to bump the settings to 10-10-10-16 since the computer is trying to set the timings for kingston to 8-8-8-14 which it does not support.

Tried to upgrade ram with 2 new pc133 sticks of 256mb ea. Didn't work. What's wrong? Are there switches on the motherboard I need to change? Or something else?


No there are no DIP switches to change, or jumpers to move on your motherboard, in regards to your BIOS recognizing ram memory installed.
(BIOS. Basic Input/Output System. This tiny program, {64MB in size usually}, that is burned into your BIOS chipset, is what recognizes ram memory on your computer)

Things to know about the older Sdram ram memory.
1.It's really SDR Sdram. Single Data Rate Synchronous Dynamic Random Access Memory.
DDR is Double Data Rate Sdram, DDR2 is Double Data Rate 2 Sdram, and so on.

Point? All ram from SDR to DDR3, IS Sdram.

2.Standards have been set by JEDEC for computer ram memory starting from DDR Sdram on up. This standards were not implemented back in the day of SDR Sdram.

Point? Ram memory manufacturers didn't all follow the same standard, and ram memory made for one computer, would Not work in another computer.
This means you need THE ram memory for YOUR eMachines computer.

Main factors when buying SDR Sdram,
A.Correct type. You know this. SDR Sdram.
168 gold plated contact pins on the bottom of the ram 'stick'. (82 on each side)

B.Correct 'Speed'. ('Speed' is slang for Frequency Rate) You know this. SDR Sdram that operates at a frequency rate of 133MHz. (Or also known as PC133)

C.It must be low density Non-ECC ram memory. It cannot be high density ECC. (Error Control Correcting. Used for Server computers mostly)

D.Correct CAS Latency. Also known as Ram Timings. 3-3-3-3-2 would be normal for SDR Sdram.

E.Correct Chip Configuration. How the DRAM chips are accessed. DRAM chips are the black rectangular chips on each side of your ram memory 'stick'. Also what size the DRAM chips are in MegaBytes. (MB)

F.What the Maximum TOTAL Amount is for the motherboard. Is it 256MB? 512MB? Or more?

G.What the Maximum Amount is for EACH ram 'slot'. (Correct speak for 'Slot' is Bank)

H.Do you have four ram 'slots'? You MUST have a ram stick in Slot 1. This is the slot closest to the processor. It is the first ram slot the processor 'reads'.

2 RAMs are not getting detected together -- Intel D101GGC


hi im josh in cebu phils. friend no setting to be modified the problem is in *********** board.it can not detect two memory at a time especially having different value. coz when the memory works it will swap since one of the memory is hgher it will create complications.so to avoid such problem you choose to use the same value of memory in both memory banks. like if youre using 256 of the 1st memory bank use alson 256 for 2nd memory bank. then try to use the same brand for better. good luck!

Trying to upgrade RAM - won't boot after new RAM installed


Install the RAM on memory slot and Switch on your system and go to BIOS settings. There you can check whether your RAM is working properly or not. If it shows no memory installed then the RAM Chip may be damaged.

Dear Sir,

You can install upto 3 GB RAM. i.e. 1GB PC3200 DIMM RAM in each slot.

Please go to BIOS settings & load the defaults. / check following. BIOS settings.
DIMM clock & timing is auto/ detected by SPD (Serial Presence Detect)

Possibly the 1GB RAM you are trying to install does not have SPD / is faulty. Try with a new / working 1 GB RAM.

Hope this helps you friend...

Ram gets detected only to half of the value specified


dear pradhan

your ram 256 but i think your ram memory shared with disply memory so . first restart your system and press DEL key untill u enter in bios setup.then go tothe advanced option and disable graphic memory then save settings and restart pc . your problem is solved.

More than likely the 2nd slot your trying to use is bad, however before you make that assumption try inserting a stick in the possible bad slot by itself and see if it will post. Let us know :-)
