The P5VDC2-MX motherboard specs state that DDR2 533/400 ram is supported. Your 800 is just too fast and is forced to operate at a slow speed. It is not unusual to get half the amount of memory shown when operating at half speed.

I have intel d845gvs1 motherboard with P4 2.4 ghz, Currently have 2 ram (512mb & 256 mb) how much further can i upgrade the ram, 1GB or 2GB also is the current combination of ram is right?


"Supports up to 2 GB of system memory with DIMMs utilizing 512 Mbit
technology DRAM devices"-intel

you can use 2 sticks of 1 gig apiece to get to 2 gigs of total memory, but you have to make sure that the ram sticks use "512Mbit " technology.

the 512Mbit technology refers to the arrangement of memory chips on the ram cards. a card which uses 64Mx8 (8 seperate memory chips of 64M apiece) would be appropriate.

"Nearly all motherboards only recognize 1 GB modules if they are low density 64M×8 modules. If high density 128M×4 1 GB modules are used, they most likely will not work."-wikipedia"

I have compaq presario 5000 series...and iwant upgrade my ram ...i have 128+128 sd ram so how much i upgrade my ram...can i upgrade 512+512 sd ram OR 256+256 sd ram...thank you


the RAM upgrade will depend on ur motherboard capacity and specification.
u need to check ur MB manual
if ur MB can have only SD RAM then only SD RAM upgrade is possible...DDR will not work....
so be careful while buying ur RAM

intelD845GLLy MB...the following details are from the intel website

http://www.intel.com/support/motherboards/desktop/d845glly/sb/CS-012825.htm

System Memory Features
The D845GLLY board provide the following memory features:
  • Two DIMM sockets supporting 3.3 V (only) 168-pin 133 MHz Single Data Rate (SDR) 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 Desktop Board. Using ECC DIMMs could damage the Desktop Board.
Integrator's Notes:
  • Registered DIMMs are not supported on the Desktop Board.
  • This Desktop Board has been designed to support DIMMs based on 512 Mbit technology for a maximum onboard capacity of up to 2 GB, but this technology has not been validated on this board.




Note To be fully compliant with all applicable PCI33 SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance.
hope this helps
Reg....bye

    Your last results is running your comp OK because it is really only running on the 512 stick. When putting 2 different sizes together it will only run on the smallest, with this said here is a website http://www.4allmemory.com it will test your comp to exactly what type RAM you need . I buy for my clients all the time from this website. Very reliable,Try it..and remember about the 2 sizes

    When i add a memory in damaged DIMM slot showing black screen?


    Try moving the working DIMM to other slots, it should work in any slot, if it does, the other ram u have is incompatible or bad

    Install a matched pair of DIMMs (equal in speed: DDR266, DDR333, or
    DDR400; density: 64 MB, 128 MB, 256 MB, 512 MB, or 1 GB; and
    technology: 128 Mb, 256 Mb, or 512 Mb) in DIMM 0 in both Channels A and
    B. If additional memory is to be used, install another matched pair of DIMMs
    in DIMM 1 in both Channels A and B.
