Memory Problem I have a asrock motherboardand i cant get my motherboard to detect more than 1 Gig of memory.

Go to the website for ASRock and type in the exact numbers for your Intel 945PL based Motherboard. Being an older Motherboard, my guess would be no more than 1 Gig strip per socket, with the possibility of 512M

I did some research. You didn't say what density the RAM was, but everything I can find on the Ballistix 800 MHZ DDR2 states that it runs at 2.2V. The standard for DDR2 RAM is 1.8V. You motherboard has both and AUTO and manual setting capability for memory (DRAM) voltage. It is possible that the AUTOP feature is not detecting the need for 2.2V, and that with only one DIMM installled, the memory marginally functions, but with the extra loading of the second it will not. Boot the system with the single DIMM, go to the BIOS, and set the DRAM voltage manually to the 2.01V setting (Verify by the part number of the RAM with the CRUCIAL website that is uses 2.2V before doing this). Once you have changed the voltage in BIOS, shut down and add the second DIMM and see if things improve.

Hi, you can download a manual here:

http://www.asrock.com/mb/overview.asp?model=p4i65g

Your mainboard DOES NOT SUPPORT ECC RAM.
This ram type is ONLY intended for servers
or mainboards that are compatible for that ram type.

This is what your mainboard supports:

Dual Channel DDR memory technology
- 2 x DDR DIMM slots
- Supports DDR400/333/266 non-ECC, un-buffered memory
- Max. capacity of system memory: 2GB

Use only the asrock site when upgrading the bios.
And a bios upgrade does not supports the ecc ram anyway.

Hope this will help you.

Hi, you need to check you have the corrct memory, you need: Memory Type DDR SDRAM Number of Memory Slots 2 x 184 Pin DIMMs Supported RAM speeds 400 MHz • 333 MH

here is a link to the manual,it appears that when one slot is used its pc 3200,but when using two slots it changes to pc2700 or pc2100,hope this helps

That is the correct memory type, max of 1.5GB, and not the 2 you would expect. You can use 64/128/256/512 modules, but when using 512, only 3 are recognized, the 4th slot is disabled.

Hi,

Remove all plug-in cards including the memory and clean the contact points with a pencil eraser... Insert them back and try... You should hear 2 short beeps, which means Okey... Long beep means that there is a problem with the memory or one of the memory... Keep me posted if not solved...

Happy Fixya...

a bios flash might sot the problem

Hello there.

From your description is sounds like the new Memory is either faulty, or not compatible with your sytem, this explains the error messages and blue screens.

What i would suggest is to download a free program called 'memtest' that you can burn to cd and let your computer load it up before it loads Windows, this will check the memory for any errors and verify that indeed the memory is faulty.

You can find memtest here

Please try this and let us know what happens. If you only purchased the memory then you can get it replaced for free.

Hope this helps.

Some MOBO support different type of memory modules like ddr 400, 333,533 and other, if your computer is working fine with that PC400 it only means that your MOBO is compatible with it. Since you're planning to upgrade the memory just get another PC400 because the memory should be the same to work fine.
