Good Morning,

Need assistance in OC'ing my i7 please.

Perhaps not the best test method but using my MSI Control Center for temps and the Intel Processor Diagnostic Tool to see if Im getting close.

I7 - 3770K
MSI Z77A-GD65
Hyper 212 Evo (one fan)
Antec 620 PSU
Samsung wonder ram

I only used BIOS for Multiplier and then Vcore:

x47, 1.4, 81c, Intel test 47c below max temp
x50, 1.4 failed
x49, 1.4 failed
x49, 1.42 - started up test then crashed
x48, 1.365, 79c, intel test 48c under max temp
x49, 1.375 crash
x51, 1.375 crash
x48, 1.375, 77c, intel test 50x under max temp <<--- Best one i think so far
x49, 1.340, 76c, crash during test - blue screen of death
x49, 1.390, started but crashed at begining of test
x49, 1.43, 82c-85c during running test - then crashed

So I know I was shooting around the targets rather than increasing step by step ... but tried to follow the general guidelines I read on the Vcore: Intel max Vcore: 1.52v, and recommended on air 1,3v-1.45v.

Not sure what other settings I should try but would like to get over 5.0 to at least see the limits ... but need more educated process beyond my blind guessing that got me to the 4.8-4.9 ish range.

Is best path forward to jsut use x48, Vcore 1.374v and walk the Vcore voltage up and down from 1.375 in .005 increments to see the range of Vcore values that the 48 multiplier works with. Then use the midpoint of that range to increase to the next multiplier?

Or what I think ... there has to be another setting that Im not aware of that helps with this ... that my internet searching (only a few days of forum reading) has not discovered ...

Thanks in advance!

Loose

Thought I might add that Im still on the x49 and 1.43 V core setting ... working fine for this but of course failed during the Intel test.

Thanks - Read those guides along with others ... and understand that too high or too low voltage will fail ... guess I will give it a re look and start from the bottom up and go in increments ... was hoping there was another setting that was recommended by experienced OC's.

Was also trying to skip through 50 trials and get a rough idea of where to start in the higher 4s instead of from 3.6 ...

Is that 3770k delidded? 77c at 1.375v cpu vcore is really good temps.

Like others have said, start from the beginning and start by raising cpu multi, then cpu vcore. Have you considered using prime95 to test stability?

I suggest writing down all your settings too, and avoid randomly changing different settings in an attempt to get stable, this can make things even more difficult.

Not delided ... and I jsut found out what that means like 2 days ago ...

I was doing some quick fire sampling to see what relationship path my chip is on in regards to multiplier/voltage/wattage and the dreaded heat ... from all my looking up threads and the mass of information (sometimes conflicting) on the subject, I thought I would try to dial in faster that way. A simple plot of successes and failures was good for me to see what "right" can look like since this is my first time and I was being impatient.

I will use the prime95, was scared to leave it run unattended without having some knowledge of what my temps would be.

Think I got lucky on my chip (but still giving me grief at x50) and installed my 212 EVO (best air cooler in the world) correctly ... trying to learn the other settings because I will get this chip over 5.0 GHz!
