I bought these sticks off Ebay M393B5170EH1-CH9, two of them, but my mainboard which is a m4a78lt-m Rev 1.00G, will not POST with them or enter BIOS. I've already followed the procedure of clearing the RTC, but it still won't POST and I assume they're dead or somehow incompatible.

It's not my mainboard either since it can POST just fine with the memory I'm trying to replace. Thank you for your help.
 
Solution
That appears to be ECC memory (like used in a server or workstation) that your motherboard may not support. They will definitely cause an issue if you have non-ECC "regular" memory also installed.
