Hello everyone 
My motherboard is a Sapphire pure black X58, with 6 ram slots ( tri-channel ) and 3x 2GB G.Skill PC12800 PI series on them, and when I received for free 6x 2BG G.skill PC12800 NQ series I wanted to upgrade my system. But the problem is that when I plugged my memory everything seemed a lot slower, the UC was at 20-30% on idle, launching any single application would make it 100% UC.
So I've tried removing modules one by one, and plugged them them separately, and it seems that, for every combination, when I have more than 4 DIMM's plugged everything goes slow.
I've moved the 4th module into every empty slot so they should all work. And all the RAM work as well when they are only three.
I've also tried to mix them with 2x 2GB G.Skill PC10600 NT series (those are dual channel), with the same results.
Every module has been tested on another computer two by two, and they all seemed to work fine.
I've also formatted my drive and reinstalled windows, same thing happens.
There is no update for the BIOS on Sapphire's site.
I found here that activating the onboard video card could solve the problem, but I don't have one, so there's that
And finally I've looked into the memory voltages and timings, so far the voltages seem normal but i'm confused by the timings, I'm not sure if my motherboard is adjusting well or not. So I have multiple reports from CPU-Z (I'll join them ), for every combination tested.
Here are the motherboard's timings from CPU-Z (only the two first combinations works):
3x NQ: 7-7-7-20
3x PI + 1x NQ: 8-8-8-20
3x PI + 2x NT: 8-8-8-20
3x NQ + 2x NT: 7-7-7-20
3x PI + 3x NQ: 8-8-8-20
It looks like they don't match the memories timings at all, am I missing something here?
I've tried forcing XMP Profile with 3x NQ's and 3x PI's once and I got a nice BSOD
Anybody have an idea on this? thanks
