The memory is:
Mushkin Enhanced Blackline 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model 996587
I have found a few data sheets on this, so I know that it is unbuffered, runs at 1.8v by standard, etc. The only thing I can not find is if it is ecc or non-ecc, so I was hoping someone here knew. I really don't want to run the risk of buying two of these kits just to find out my motherboard won't take it.
