Its a new build. I haven't touched the settings. Everything is set to auto. I haven't overclocked anything, its all stock. The sticks are from my last build I did in 2011, which was a i5 Sandy Bridge 3.3ghz quad. And this one is a 8 core AMD FX 4.0ghz. Motherboards are different. The new one is a Gigabyte 970A-UD3P.
I was having an issue with this new system just randomly rebooting and I noticed I had the memory in slots 2&4. So I moved the one from 4 to 1. Now they are in 1&2. I haven't had a reboot in 2 days. System seems ok, but like I said the when both sticks are installed Aida64 fails the memory test. If one is installed its ok.
On a side note...How long am I supposed to let the tests go on for? Will they automatically stop?
