MB keeps beeping 1 long beep no boot.

Hello try to download the manual:

Select windows xp and open the manual folder
Click on global for download.
Unzip the file and you need adobe reader to read the content.

Here is a list of beep codes:

This mainboard uses SD ram and it sounds like a ram problem.

If there is room for a ddr ram block you can`t use SD ram and DDR ram simultaneously.

Try to insert the old cpu again and upgrade the bios to support a bigger cpu. Not all cpu is supported.

Good luck

You should be able to as it can take 4 gig total according to the manual.

Supports dual channel DDRII 667/533 unbuffered DIMMs (Note 3)
Supports 1.8V DDRII DIMMs

I had 256 ddr2 ram (PC667- Hynix) in my machine and it was working good and to increase more speed i had installed another 1Gb ddr2 ram (PC667- Hynix) in another slot but to my surprise it is found that...

The simplest answer is to use the 1GB ram only.
That should give you an improvement from 256MB, but the difference from 1GB to 1.25GB may not be noticeable.

You could try the changing the order the you put them in the slots and see if that works.

As to why it does not work is not that simple.
The motherboard may not be set up to run with a combination of single or double sided ram. if that is what you have. Or it just might not work with the combination of memory that you have.
The manual on the link below mentions approved memory and it appears that suitable 256MB sticks are single sided, and 1024MB (1GB) are double sided.
The A and B examples mention single and double sided, but don't specifically say the two are mutually exclusive.

Again, it might be better to ignore it all and use your 1gb memory machine.

Hi, i was windering if it was possible to use 168 pins pc133 memory modules instead of the ddr 266 into my P4B266 Motherboard, since they have the same size and work at the same frequency. In the manual,...

*********** board will suport for 133 bus speed memory.Memory Size is not the matter,what ever you can install in the mother board,may be 128/256/512,but ensure the bus speed .It wont be more than 133 mhz.,then your mobo can not support.If you have SDR 133 bus speed ram you can install .
*********** board speed is 400 mhz,you can change 478 pin any intel processor,for better performence but the bus speed would be 400 mhz or bellow 400mhz,both will be suported.

For detail follow bellow the link.

Hope it will you.

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

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, Replacing my 256mb ram (1 slot) with 1Gb (2x512). The computer would not boot. Removing 1x512 memory the computer works fine. I put my old 256Mb back with the 512 Mb and the system only reported 256Mb....

Is the speed of the RAM the same mixing PC 133 and PC100 ram can cause problems working together. Also it sounds as if your board will only upgrade to a maximum of 512 MB total.

PC Motherboard Memory upgrade

From Asus tech: Memory 3 184-pin DIMM slots for PC1600/PC2100 DDR SDRAM
Supports up to 2GB memory
No ECC supportThis is only compatible RAM so make sure your new chip is PC1600 or PC2100. If you mis the 2 it the faster RAM will run at the slower chip speed. Hope this helps.
