4770k and memory voltage

post #1 of 5
Thread Starter 
The Corsair Dominator Platinum 32GB (4 x 8GB) DDR3-2133 Memory operating voltage of 1.65V exceeds the Intel Haswell (4770k) CPU recommended maximum of 1.5V+5% (1.575V).

Tradesman1 (from tomshardware) said:
Have yet to hear of a 4770K that can't handle a minimum of 2666, even 3770K can handle that.....as long as it's not a cheapie mobo, there should be no problem....as far as Intel they ALWAYS just list their bare basic specs and also tell you they don't support OCing a CPU - "it voids the warranty", so why then do they make OCable CPUs....even the 4670Ks can handle 2666....2400 is no biggie for a K series CPU..........

My question is, in theory, I can go DDR3-2133 cas 9 as stock clocks with Maximus VI Formula? I might get the 2133mhz and try it anyways - if I have to undervolt, well, I will.

Unless someone has personal experience on this and suggests otherwise?

Thanks,
Marcus

You should have no trouble. I ran 1.65v 2400mhz with my 3770k and now run cas9 2133mhz at 1.6v with my 4770k. Never had a problem. I do however have to drop the voltage and clocks to OC at 4.5ghz, 4.4 has no issue. It's something I'm still working on.

You're saying I should be fine OC'ing up to 4.4 with cas9 2133? Excellent! Thanks for sharing ^^

No problem and you may not have issues going past that. It's just some trouble that I'm running into.

I run DDR3 3000 at 1.7v on a daily basis with no issues. I've never seen anyone kill their chip with 1.65v memory voltage
