Can I replace 256 MB SD RAM with 512 MB DDR1 ram in intel 845 glly mother board?

Intel 965 Series Mother Board is suitable for this.

u can use the 1gb ddr1 ram,if the sound is coming then may there is two problem

1.may be the ram is damage

2.your motherboard is not supporting 333mhz bus support

try to find 400mhz ram instead of 333mhz

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

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

Hi Friend,

Yes, You can use 2GB ram in both slot...

1st try to exchange the cards in the slot.
2nd try another card
3rd ur RAM slot may not be ok
4th ur RAMs may not be compatible
5th ur new RAM card may not be ok
use same type of RAMs, and same size...
if u have 256, add 256
if u ahve 128 add 128
if u have SDR then dont add DDR
getting compatibility is little difficult...
some times no combinations can work...
note...technology keeps changing...so a old RAM card that was bought years ago may not be compatible with a new RAM card....
even i got all my old RAM cards(256+128) removed and got 2 - 512mb of the same type fixed...even i had issues with my RAMs for 6 months...

Yes other frequency RAM will not support in your motherboard.You can purchase same frequency RAM which is available in your PC.

Normally 512MB is a good configuration of Ram to work with Windows Xp Sp2 but you have clean your temporary files frequently

Increasing RAM will not give you much speed difference because first you have study the Motherboard Bus speed and the cache memory - Actual speed increase from those things and the compatibilty.

Changing Ram you have to determine what type of ram and its bus speed whether its a SD Ram or DDR1 or 2 I hope now days SD ram cost more because its outdated and DDR1 is also bit costly than DDR2.

Hothawk

try update the system bios because there were motherboards that had compatibility problems, this board is not a new one so it should work with your processor

no, everything should work fine.
