What memory are you running with that 5.0GHz overclock?

I have 4 X 4GB Corsair Vengeance 1866MHz sticks atm, looking at some Corsair Dominator Platnium 2400MHz kits. Is it recommended to run them or will I have stability issues? I gotta run quad kits right? Its for best performance from what I understood reading up on memory on the x79 platform.

Thanks again

Just be aware of the 2400mhz dram write bug its the last 6 posts on that page smile.gif

So it's not really worth it for me to move to 2400MHz? Is it dependent on the X79 chipset or asus mobos?

Im guessing there is not much difference from 1866MHz to 2133Mhz frown.gif

If you overclock to 2133 then there will be not that much difference from 2133 to 2400 biggrin.gif

I kind don't want to risk stability trying to overclock my 4 dimms. It's gonna introduce more variables for BSOD's when I finish overclocking the 3930k.

Right now I am at 4.3GHz @ 1.34v don't know if that's good or bad opinions? I will try to finish OC'ing the cpu today after work.

it's a bit high i think if your cpu is in the average you can achieve 4.5-4.6 with the same voltage

I'll be happy with a 4.5-4.7 with 1.4 or less smile.gif

So from 4.3Ghz 1.34-1.35 is stable but to get it to 4.4Ghz I needed 1.395v. I tried jumping to 4.5 and gave me IRQL NOT LESS OR EQUAL. Researched and it is usually memory issues when overclocking. Researched more and heard a loty of poeple having problems with Vengeance kits on the X79 platform. Plus my RAM is two different kits I bought them in separate occasions. I mean they both are the same speed and timings though. So im thinking memory might be an issue since the jump from4.3 to 4.4 required waaay to many volts.

Write bug is on IB-E cpus, not SB-E.

Try with only 1 kit
But it can be your cpu which is very bad.
A friend of mine have a 3930k at 4.6 for 1.5v:D
