P4M800-M7 presumed memory problem

Your machine has 4 DIMM slots. They use PC3200 (DDR400) DIMMS (184-pin). The machine comes pre-installed with 2, 256MB DIMMS providing 512MB of RAM. The largest DIMMs available in the DDR PC3200 are 1GB. If you keep what you have, you can add an additional 2GB of RAM, for a total of 2.5GB. If you are running WINXP 32-bit, this should be more than acceptable. You can replace all four DIMMS and get 4GB of RAM, but a 32-bit OS can only access a little of 3GB of RAM. If you want to come close to maxing out under a 32-bit OS, remove one of the installed DIMMS and add 3 1GB DIMMS. These are old memory and may be hard to find and actually cost more than newer memory.

you can change to ddr 2gb and also add the graphic card . try ati 9200!

Info from the manual:

Memory configurations

You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into the DIMM sockets using the memory configurations in this section.

• Install only identical (the same type and size) DDR DIMM pairs

using the recommended configurations.

• Make sure that the memory frequency matches the CPU FSB

(Front Side Bus). Refer to the Memory frequency/CPU FSB

synchronization table on the next page.

• This motherboard does not support double-sided 16-bit DDR DIMMs.

• Do not create a three-DIMM configuration in dual-channel mode. The
third DIMM is ignored in the dual-channel operation.

The below is the contents of Intel published for your board
Intel Desktop Board D102GGC2 Technical Product Specification
System Memory The board has two 240-pin DIMM sockets and supports the following memory features: • 1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts • Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMS with x16 organization are not supported. • 2 GB maximum total system memory. • Minimum total system memory: 128 MB • Non-ECC DIMMs • Serial Presence Detect • DDR2 533 or DDR2 400 MHz SDRAM DIMM
hope it helps, if so rate the solution

Yes. That motherboard can handle a total of 2048 (2 GB) of DDR PC 3200 (AKA DDR 400).

The motherboard does not support 1 GB modules; 512 MB is the maximum the motherboard will recognize. Usually, the computer won't even work if the memory isn't supported but in this case it does.

Thanks and please remember to give this a thumbs up rating.

I have p4m800-m7 also and i cant seem to get both sticks to work.....I still have only 1 gig with both sticks i have 2 DDR-2 1Gig sticks PC2-5300 533 mhz

Kingston Value Ram will do, nothing over 533mhz

Greetings,

The motherboard will read 1GB DDR400 memory per slot only.

Keep us posted and thank you for using our service.
FixYa for all your troubleshooting needs.

You can use only DDR 266Mhz dimms maximum upto 2 GB. i.e. one DIMMS of 266Mhz of 2GB or two of 1GB each. For more details read bellow:


System Memory Features

• The D845GBV board provide the following memory features:
• 
  Two DIMM sockets supporting 2.5 V (only) 184-pin 200/266 MHz Double Data Rate (DDR) SDRAM DIMMs with gold-plated contacts
  Unbuffered non-ECC DIMMs only
  Maximum total system memory: 2 GB; minimum total system memory: 64 MB
  Serial Presence Detect (SPD) DIMMs only
  Suspend to RAM
• 
  CAUTION:
  Do not use ECC DIMMs with the D845GBV board. Using ECC DIMMs could damage the Desktop Board.
