Hi All,
Just completed my first properly set up overclock on my System. I know I could probably push it a bit more (its a 2011 Sandy Bridge-E - so 1.4v is the Intel Spec on volts), but I don't want to wear out my CPU prematurely.
I'll start with the stock settings, then the OC settings. Please note that core temps are of the HOTTEST core only.
CPU: Intel i7 3930K
RAM: 32 Gig 1333 Mhz Corsair Dominator
Motherboard: Rampage IV Extreme
Cooler: Corsair H100i
Stock:
Volts: 1.175 (Was running at 1.2 however according to CPU-Z)
Speed: 3.2 GHz
Stable? Yes
Temp: Ambient: 25 CPU: 61 - Delta: 36 (all Celcius)
Undervolt:
Volts: 1.1 (1.05 = crash)
Speed: 3.2GHz
Stable? Yes
Temp: Ambient: 30 CPU: 58 Delta: 28
Overclock:
Volts: 1.2 (1.175 entered into bios)
Speed: 4.1 GHz (4.2 = crash @~10 minutes of OCCT test)
Stable? So far, yes (30 minute test done, doing longer test now)
Temp: Ambient: 25 CPU: 69 - Delta: 44
Total overclock (Assuming that 4.1 turns out to be totally stable): 28.1% @ stock volts.
What are your thoughts? Should I keep going, or is this good enough for a day to day machine? Should I revisit it once I get my custom loop done?
Screenshots will be incoming once I am certain that 4.1 is stable, otherwise I will have to dial it back one more to 4.0 (which was my last confirmed stable after 4 hour each OCCT and Prime95 test and is still a 25% overclock @ stock volts).
Edit: I can't tell if the 4.1GHz overclock is stable or not. Is there such a thing as mostly stable? 1st test: crash @ 36mins. Second test: no crash after 2 hours. Third test: Up to 1 hour now, no crash so far. The only difference between the first and second test is that I had AVX Compatible linpac selected for the first test, and not the second. BUT, I've also get it selected now while running the third.... so I don't think that is it...
Edit 2: third test crashed. Avx Compatible Linpac causes a crash @ 4.1..... So my over clock is unstable?
