This is why you don't mix sticks from different packages, in a single package the sticks are tested to work together, tolerances are so tight in todays DRAM you more often than not can't just throw sticks together...what model sticks are they? (preferably model #), if they are 1333 or 1600 might just try raising the DRAM voltage + 0.05 and see if that helps...otherwise may need additional adjustments
I still have the bad sticks, but seeing how I got errors I'd rather not use them. And I doubt Amazon will replace the same product twice.
I have a week or so before I have to ship it back. The model is Corsair Vengeance CMZ8GX3M2A1600C9. Online and in the MB manual it lists it as 9 9 9 24 1.5V, which is what comes up in the Bios and CPU-Z.
I posted in the CPU section that my CPU came in with bent pins and I tried to get by by straightening them. Kinda dumb, I know, as I later learned that sometimes you can get a RMA. My first real build, so I expected a few bumps. Before I buy another CPU and possibly another MB, I wanted to narrow down the RAM problems. From what I've read, a bad CPU could cause RAM to not work well together.
Also, with a single stick I can run Prime 95, but with two the system freezes, requiring a hard restart.
It also freezes with just about everything else given enough time.
Oh, and memtest doesn't fail, it freezes. My bad on that.
I will try increasing the DRAM voltage by 0.05. Thanks!
