This is correct. Although I would adjust the memory voltage to 1.65, then up the VTT till its all there (slowly.)



Its a CPU IMC thing. It doesn't have enough juice to get it all started. As stability goes, this falls between computer not posting to memory errors with a BSOD. Since it doesn't have to run all the memory, it is slightly more stable too, so make sure to run some Prime95 Blend testing with custom sizes, or just run 100 or so passes with IBT.

Are you using ECC memory? Because that will obviously give you false reports on tests passing.

Contrary to popular opinion, RAM slot issues are seldom defective motherboards but too much tension on CPU socket combined with big, heavy, aftermarket CPU coolers.
Contrary to popular opinion, I would think that a very high percentage of RMAs are from poor user setup.

Okay cool, wasn't sure if you were running something else

I have to help out my fellow brits I like the sig too.

To touch up on that memory timing +2 I suggested, it maybe slightly different for the SR-2, you definitely want to go through the memory timing list.

It may be called something different on your motherboard, it will have (should) a description that says "Try +2 if memory disappears with OC." Thats the one that needs +2. So if I didn't get it right, look for the description okay?

If you can't find it, I will look for the SR-2 equivalent. This isn't just an EVGA thing, but they do have a work around for it.
