P4M800P7MB RS2H Foxconn motherboard and 2G memory upgrade

Please help

I've got the following:
CPU name: Intel(R) Celeron D CPU 2.66GHz
Motherboard model: P4M800P7MB-RS2H
BIOS Name: Phoenix- Award V6.00 (584F1P12)
Memory device: 512M DDR2
OS:Windows XP Home+SP2

I've got two 512M DDR2 RAM in the memory slots at the moment.
I replaced it with two 1Gb DDR2 800's , but it registered only as 1Gb total memory with both cards in position. When I removed one of the 1Gb cards, it registered as only 512Mb memory. I got the same results with the other 1Gb card.
According to the motherboard's manual is support up to 2Gb. It also support DDR2 533/400. The shop where I bought the 2Gb's said it will work with the motherboard, but the speed will not be 800mb, but 533mb which is understandable.
The PC boot normally and so does everything else, except that the RAM is only 1Gb where it should be 2Gb with the two 1Gb cards.

    My problem is similar. I bought 2 Crucial 1Gb Memory Modules which they say are suitable for the Foxconn motherboard. Ref no 1GB 240 PIN DIMM 120Mx64 DDR2 PC2 - 5300 UNIBLUE. When I installed the two Modules to replace my 1 512Mb module the computer just gave long beeps and refused to start. I relaced the single 512 module and all was OK. When I then installed 1 of the new 1Gb modules in slot 2 the computer booted up and reported 1Gb of memory. Crucial suggest it is a BIOS problem from your post from diffie I'm not so sure!!

The 1gb memory modules need to be low-density ie chips on both sides. the motherboard can only recognise 512mb on each side of the memory module.

I went back to the shop where I bought the RAM - they haven't got slower RAM. There they replaced these two DDR2 1Gb 800 with equivalent RAM. The only difference being the set causing the low RAM value of 1Gb is a Samsung make and the the set of which the total RAM is 2Gb, is a Transend make. Everything is working now 100% ok

U'll have to keep the speed of the ram within the limits of the processor. Exchange the new ram for the slower ram and it will be 2 gb.

CPU upgrade for Compaq SR1220NX Desktop Computer


Hi
The specs for this machine state that it is a motherboard with
"Socket 478 for Intel P4 Williamette and Northwood processors
Supports Intel Pentium 4 processor up to 2.8 GHz
Supports Intel Celeron processor up to 3.06 GHz (Prescott based Celeron with 533MHz FSB)"
In other words, any CPU that is not socket 478 ( a fairly old socket now) will not even fit on the board. You do not mention your current CPU so you need to compare it with the spec above to see if you can improve it. It is an old machine/motherboard, so your money might be better going towards a motherboard or system box upgrade.
Cheers

Dc5100 processor upgrade


NO!

Two Netburst based Processor cores on the SAME chipset?

Get outta' here!

When did they come up with that?





OH, I'M JUS KIDDIN'!

http://h18000.www1.hp.com/products/quickspecs/12145_na/12145_na.HTML

The HP Compaq dc5100 Desktop PC uses an Intel 915GV motherboard chipset.

Since we know that the Northbridge chip, of the motherboard chipset; handles the Faster capabilities of a computer;
i.e., Processor, Ram Memory, and HIGH-speed graphics; let's look at the Intel 915GV chipset,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4.2FPentium_D.2FPentium_EE_chipsets

No sir/ma'am.
The Intel 915GV motherboard chipset only handles Single Core processors;
Intel Pentium 4,
and,
Intel Celeron,
and,
Intel Celeron D.
(With a 533MegaHertz Front Side Bus, or an 800MHz FSB)

The Celeron D is NOT a dual core processor,

http://en.wikipedia.org/wiki/Celeron#Prescott-256

"The D suffix actually has no official designation, and does not indicate that these models are dual-core. It is used simply to distinguish this line of Celeron from the previous, lower performing Northwood and Willamette series, and also from the mobile series, the Celeron M (which also uses 3xx model numbers) Unlike the Pentium D, the Celeron D is Not a dual core processor."

Yeah, I know. I'm just a 'Ray of Sunshine'.

You know you can pick up a motherboard pretty cheap nowadays, that WILL support the lowly Pentium D, for not much money.

Problem is you will need to replace Ram Memory also.

By the time you get a motherboard chipset that supports dual core Processors (CPU), you are going to be using DDR2 Sdram ram memory, instead of the DDR Sdram ram memory you are using now.

OK, Motherboard, CPU, and Ram Memory.

Oh, the Power Supply. Won't do either.
240 Watt unit, or 300 Watt unit?

Sure.............OK.

Back in the day those Power Supply's were made, Power Supply manufacturer's were 'fudging' the actual maximum rated Wattage.

True Wattage was more like 60 to 70 percent of what was stated.
Why?
SOLD more Power Supply's.

240 Watts?
Simply divide by 10. = 24.
For 60 percent, take 60 times 24. = 144 Watts
70 percent? 168 Watts.

300 Watts?
60 percent is 180 Watts.
70 percent is 210 Watts.

I wouldn't try to run a Barbie doll with that low a Wattage, of Power Supply. (Barbie doll? What?)

Need at least a decent 350 Watt power supply, from today's manufacturers.
80 percent constant duty cycle, for most good units; or higher.

So...............
Max out the Intel Pentium 4 CPU.

4GB's of 533MHz DDR Sdram ram memory.
(PC4200, or PC4300. Depends on the manufacturer as to how they name it)

By the time you spend that much money, you may as well buy another Motherboard, Processor, Ram Memory, and Power Supply.

Yes, may as well buy a better computer.

I know. Quit trying to cheer you up.

Around here we have Craigslist, and Ebay, for two places.
Could pick up a better computer, for around the same money, as you would pay for all the upgrade parts above.

Which is better? Upgrade the Processor, or upgrade the Ram Memory/
For the better 'Bang for the Buck', upgrade the Ram Memory.

The CPU (Processor) has a built-in cache.
L1 cache, and L2 cache. (Newer CPU's have an L3 cache)

The Cache is a small memory area for the CPU.
It is the FIRST memory area the Processor (CPU) reads.
This is because it operates at the same frequency rate, as the CPU does.
(Frequency rate = 'Speed'. Operates at the same 'Speed')

Next inline is the Ram Memory.
Ram Memory -> typically, operates at half of the Processor's Front Side Bus. (FSB)

This is why upgrading Ram Memory is a good idea.

It isn't so much of getting Ram Memory, that operates at a higher frequency rate ('Speed'), as it is to have MORE ram memory.

Example;
PC3200 compared to PC4200.
4GB's of PC3200 is better than 2GB's of PC4200.

(DDR Sdram at 400MHz = PC3200)

Moving on............

Motherboard chipset:

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

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

The motherboard chipset for your computer, consists of a Northbridge chip, and a Southbridge chip.

{Motherboards that support the Intel Core i technology, (Core i3, Core i5, Core i7, etc), do NOT use this motherboard chipset technology. Neither do some of the AMD CPU's }

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

As stated previously, the Northbridge chip handles the Faster capabilities of a computer;
Processor (CPU), Ram Memory, and HIGH-speed graphics.

The AGP technology, and the PCI Express technology; ARE high-speed graphics.

Using a graphics card in a PCI slot, or using Integrated Graphics; is NOT high-speed graphics.

The slower capabilities of a computer are handled by the Southbridge chip.
1) PCI Bus / Integrated Graphics.

(Another term for Integrated Graphics, is OnBoard Graphics. A term that seems to have gotten lost.
It explains better; ON the motherBOARD )

2) IDE Bus
3) SATA Bus
4) USB Bus
5) Ethernet
6) Audio (Sound)

Point?
Look to see what the Northbridge chip is, as I have shown you; and you'll get a good idea of what Processor (CPU) support is.

For additional questions please post in a Comment.

Installing new cpu on a emachine


According to the specs I have Serena, the eMachines eTower 633i Desktop PC, uses a TriGem Cognac motherboard.

[TriGem is the manufacturer, Cognac is the model.
Note it is Not the TriGem Cognac+ ]

http://www.motherboards.org/mobot/motherboards_d/Trigem/Cognac/

Specifications. (You can click on the photo to enlarge)

PDF motherboard manual,

http://www.elhvb.com/mboards/TriGem/manuals/index.html

Click on - Cognac - in the left side of the list.

Going back to the Motherboards.org page;
(Nothing like upside down photo information, and the motherboard is turned 90 degrees to the Right, to how it actually sits in your computer case )

The processor socket is a Socket 370,

http://en.wikipedia.org/wiki/Socket_370

Used for Intel Pentium III processors, and intel 'Celey' processors.

(Excuse me......Celeron.
An Intel Pentium III processor has TWICE the L2 cache, that a comparable Intel Celeron has.
The cache for a Processor is a small memory area for the Processor.

It is the First memory the Processor accesses.
The Ram Memory is second, and the Harddrive is third.
More cache for a Processor makes it more faster )

The motherboard chipset is an Intel 810.

The Northbridge chip of the motherboard chipset, is an Intel 82810.
The Southbridge chip is an Intel 82801AA, or an Intel 82801AB.
(Intel ICH, or Intel ICH0 )

Looking at the chart, and reading across, you can see what the Intel 810 motherboard chipset supports;

1) Processors: Intel Celeron, or Intel Pentium II, or Intel Pentium III.

2) Processor Front Side Bus: (FSB) 66MegaHertz, or 100MHz.

3) SDR Sdram ram memory at 100Megahertz.

[Single Data Rate Sdram is often just referred to as Sdram.

Erroneous.
Double Data Rate Sdram is also Sdram (DDR Sdram)
Synchronous Dynamic Random Access Memory
So is DDR2 Sdram, and DDR3 Sdram ]

Also referred to as PC100.

So when looking for a CPU you look for;

1) Fits in a Socket 370 processor socket.
Yep. The best is going to be an Intel Pentium III.

2) Has a FSB of 100MHz.

Hmmm,............

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_III_microprocessors#.22Coppermine.22_.28180_nm.29

Scroll down.

Pentium III 1100.

Maximum frequency rate ('Speed') is 1.1GHz (1100MHz)
Front Side Bus = 100MHz
Uses a Socket 370 processor socket.
Part Number = RB80526PY005256
sSpec Number = SL5QW

In the top header -
Specifications / Pictures (1) / CPU ID (1) / Comments (1),

256MegaByte of L2 cache. (256MB)

A comparable Celeron would have 128MB of L2 cache.

[ Don't forget to follow Anti-Static Precautions.
Clean the bottom of the Heatsink THOROUGHLY, and the top of the Processor if it needs it. (I always do anyway)

PROPERLY apply fresh, new Thermal Paste.

Can I upgrade Celeron -D 2.26Ghz to the same mobo ie. E219882


Intel E219882 motherboard, also know as Intel D850GB?

No.
1) The motherboard has a Socket 423 processor socket.

http://en.wikipedia.org/wiki/Socket_423

This processor socket has the socket holes, while the processor has the pins. Has 423 socket holes.

The Intel Celeron D 315 uses an LGA775 processor socket.
LGA775 is also known as Socket T. Has 775 pins in the processor socket. The processor used has the socket holes. 775 of them.

Celeron D 315 spec's,

http://en.wikipedia.org/wiki/List_of_Intel_Celeron_microprocessors#Celeron_D

2) The Intel D850GB motherboard only supports Single Core processors. Not Dual Core like a Pentium D.
Must be an Intel single core processor, that fits in a Socket 423 processor socket.

Intel only made processors to fit the Socket 423 for about 2 years. Intel had a deal with Rambus, for memory to fit Intel's motherboards, for this period of time. The deal fell out, and Intel moved on.

The Intel D850GB motherboard Only uses RIMM memory modules, ('Stick/s') made by Rambus.
(RIMM. Rambus Inline memory Module)

Highly expensive, overrated ram memory.

Compitable processor with Foxconn 45GM/45CM


Here is FoxConn website and shows what processors would be compatible.
You may need to upgrade the bios, and remember.
If you go to high your other components in your machine may not be compatible.
i would try and contact support at foxconn and see what they say about upgrading.

Ram upgrade capability


Simply, yes you can. just open the case and put in the new boards. you can buy higher spec. memory(as long as the pins are the same number)
I.E. ddr-sdram boards will fit and as long as the speed is the same (132.8 Mhz) or higher.
I changed from 133Mhz to 333Mhz and the performance was much improved.
The PC3200 is the important bit, should be the same.
after you change the memory ,try running disc clean up in "start, all programs, accessories, disc clean up" this will also speed things up as well as de-fragmennting your drive(s)
