|Ram that works in another mboard , or any ram you buy or have lying around, may not work properly, or sometimes, not at all - even if it physically fits and is the right overall type (e.g. SDram, DDR, DDR2, etc.; PCxxxx, xxx mhz) for your mboard. The ram has to be compatible with the mboard's main chipset, or in the case of recent mboards, compatible with the memory controller built into the cpu.|
Only two OCZ 2gb module part numbers are shown as compatible:
If one of those isn't what you have, there's nothing wrong with the ram - it's just not compatible with your mboard, and there's probably nothing wrong with your mboard..
Sometimes incompatible ram modules work fine when installed by themselves, but more than one will NOT work fine.
See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
Correction to that:
Once you know which module ID strings (part numbers) work in your mboard, you can get them from anywhere you like that has ram with those ID strings.
