I did not get any where with my E5-2670 overclocking on the Sabertooth X79. May buy a better CPU seems too good a board for a stock CPU. Then Ill have to buy another dual x79. It will never end!!! Can't have a CPU just laying around!!!
Tried the blck strap, lowered the CPU to 13x and the ram to 1033 and raised the blck strap 1 setting to 1.25 and could not boot.
So I do believe there is no overclocking these CPUs, except the E5-16xx and they are no cheaper than the i7 x79 CPUs.
I do know my E5-2670 is throttling down, I think it is wattage not heat. Using a water AIO and my temps is 60c
The Haswel is 100% faster than the x5660.. The X56xx takes 50% longer than the E5-2670 Sandy.doing prime grid (think prime95)
The X58 is still holding its own for sure. As far as game and programs that do not use the new instructions like AVX SAndy B, AVX F16C Ivy B,, AVX AVX2 F16C Haswell.
For me doing BOINC they make a huge difference. Here are times in seconds for primegrid (think prime95) I'll do Non-AVX project WCG maybe. Will be in a couple days
