I have two unused sticks of Crucial DDR2 PC2-6400 that Ive been trying to test recently with no luck. The ram says CT25664AA800.Y16F and BL1117P.T2
First I tried it (the pair) on an Asus M3A78-EM motherboard with the Corsair XMS2 memory that I already had installed. Second, I tried it alone without the Corsair memory. In both cases, the computer would not post or give what I call the happy beep with the Crucial ram installed, but I understand that this motherboard can be fickle with memory not on the qualified vendor list.
Currently, I have custody of an Acer Aspire AM5100-U5300A desktop computer, so I removed the original ram and installed the Crucial ram for testing with the same resultsnothing on screen, no beep. I have also tried each stick individually.
I have no reason to think the ram didnt seat correctlythe side clips snapped in place on their own. Both computers are perfectly happy again when I re-install their original ram.
For the sake of curiosity, is there some difference between what I have:
Crucial CT25664AA800 2GB DDR2 PC2-6400 DDR2 PC2-6400 CL=6 Unbuffered NON-ECC DDR2-800 1.8V 256Meg x 64
versus the seemingly identical one Crucial guarantees compatible with the Acer M5100 ?
Crucial CT7582122GB DDR2 PC2-6400 CL=6 Unbuffered NON-ECC DDR2-800 1.8V 256Meg x 64
I know the ram could conceivably be bad, but both sticks? Any impressions?
