What Voltage is the Ram running at and does it match what they should be at ?? From the link you posted they say the are rated at 1.8v - it could be the MOBO is not providing the right voltage making them unstable - check CPU-z and see what it shows them running at and if it is low then go into the BIOS And increase the voltage a small amount and then try Prime95 again. ( could be either the MOBO or the PSU are supplying slightly less voltage than needed which could cause the problem !)
Both are showing a 1.8V is CPU-Z.
I DO NOT have the latest bios, as it is beta.
I have not tried one stick of ram at a time, though I've ran the ram thru Memtest multiple times for hours on end and never returned a single error, both as Dual channel and single slot.
sorry forgot your other question hundredislandsboy, i have ram no other tests yet, though my brother has on his rig and they all came back fine, including an 8 hour burn in. Just immediately freaked when prime failed, heh
