4770k Oced Stable or Not

[liakos]

Hi, Ive oced my 4770k to 4,3 ghz runned prime95 for 2 hours not a single BSOD tested with OCCT and after 5 minutes BSOD comes up. Any clues which programm to trust? Plus before i try OCCT computer is already used for gaming lots of hours but not a single BSOD.

I ve got those settings:

CPU Base Clock: Manual
CPU Core Ratio: 43
Intel Turbo Boost: Disable
Cpu Enhanced Halt C1E: Disable
C3 State Support: Disable
C6/C7: State Support Monitor: Disable
CPU EIST Function: Disable
CPU VRRIN External Override: 1.8v
CPU VCore: 1.250v
CPU RING Voltage: 1.050v

Thats not much of an OC. Try upping to 4.6ghz or more and prime95 is a pretty good measuring stick.

Well its enough for me tried 4.6 with 1.3 Vcore but BSOD after started the occt. But the question i ask is very simple. Should i keep 4.3 after getting BSOD with OCCT or trust prime95 which the oc did not BSOD?

Depends on what you run on Prime95, did you test memory as well or just the CPU?

1.3 vcore is also not much high. Maybe you should try getting it higher and testing the temps and stability. I'd go up to 1.45 vcore myself.

CPU only.

Prime95 settings:
Preset: Custom
Min FFT: 1344
Max FFT: 1344
Run FFTs in-place: Checked
Min FFT: 8 Max FFT: 4096
Run FFTs in-place: Checked

Intel recommends 1.3-13.5 max Vcore.

It's possible that your RAM is causing the problems. May want to run a combined stability test.

P95 isn't a very good overall stress test, but it is excellent (v26.6 small fft) for temp maxes. Occt, especially when running linpack, is much more intensive on the system as a whole. If you are passing p95 with no issue, you really aren't stressing the ram or VRM's or MC, just core temps. What you could try is bumping the ram voltage up a notch to 1.505 or 1.51 and give the MC something to work with.

At 4.6GHz you shouldn't be at higher than 1.3v vcore. There's more needed than just moving multipliers, you'll need to bump up the llc to med (50%), adjust current usage to 110%, drop any Eco settings, disable phasing, c-states below c-3, maybe adjust pll to 1.9 or 1.7, change long duration limits to 255 etc. Apart from the Asus ROG mobo's, msi runs the most intensive OC bios, has lots of settings not normally found or user adjustable, most Giga, ASRock and cheaper Asus lines have bios that's simpler and more user friendly, but that's offset by lowered ability.

I5-3570k @ 4.3GHz 1.114v, i7-3770k @4.9GHz 1.308v. Take a peek over at the Asus ROG forums, there's plenty of info about how ppl are getting high OC's, what they tried and what the results are. All bios are basically the same, multiplier, vcore, dram settings, pll and llc etc, just different brands and different models use different terminology, but the essence is the same.
