Is my 3770K a good overclocker?

post #1 of 14
Thread Starter 
(note: I have hyperthreading enabled if that makes a difference)

With a GA-Z77X-D3H motherboard and an H100i, I was doing 4.0 GHz @ 1.14v (it was set to auto, turbo boost was auto, and vdroop was auto) and with 100% CPU load under prime95, I was doing 54-59 degrees celcius


Now, I didn't bother going for the optimal voltage/multiplier. I just decided to crank up to 1.25v @ 4.5GHz. Using OCCT small data set (intended for max heat) I was around 68 degrees when I set the H100i fans to max speed and I was around 75-79 with the fans set to "performance".

When playing BF3 in Metro with 64 players at completely max settings @ 1920x1080 (vsync on, never dropped below 60fps) my CPU temps maxed at around 66ish degrees with fans on 'performance'

How does my CPU seem? Are there any other voltage/multiplier combinations I should try out? is 4.5Ghz overkill? Am I hurting my CPU or cooler or motherboard or any parts by running such an overclock at such a voltage at said temperatures? at what temps do I start seeing damage on my cooler, mobo, cpu, etc?

It should be noted that I had a BSOD @ 4.5GHz and 1.2v


Edit: All I do on this computer is game but I may get into some rendering/streaming if I ever want to. I don't play any MMOs atm and if I did ever go back into WoW I wouldn't be raiding 25mans so do I even benefit from overclocking past stock? Should I just go back to 3.5GHz and minimize voltage for lowest temps?


Edit2: Forgot to say, after I tried going over 4.0 I turned turbo boost off, vdroop to extreme, and disabled voltage autos for many things

I'm not sure if that's a "OMG AMAZING" type chip, but you're within the high-end range with that OC.

i7? Check. 4.5ghz? Check. Good temps? Check.

Looks good to me buddy. No such thing as overkill here.

Are these truly good temps? At what temps should I start to get worried?
post #4 of 14
I have a 3770k and an h100i as well, and for awhile I had it stable at 4.5ghz and 1.25 volts. After a few months, I decided to try and get some lower temps so i dropped the voltage a bit and went to 4.2ghz and it works quite well, with temps maxing out at about 70C on maximum heat test from P95. If you're okay with that kind of temps, and the processor certainly doesn't mind, (80 or so is where I'd begin to worry) then there is no real reason not to keep it overclocked, as long as its stable for you! thumb.gif

4,5 ghz is fine and standard. Good OC and also safe.
But 4,5 Ghz @1,25 V is not that great. There are better chips out but it could be much more worse.

Mine run @1,288 V and max. 80°C with the noctua NH D14 but it cant go beyond 4,5 ghz.

When you game your temps should be below 60 - 70°C and then its fine. Prime95 is a different story but it shouldnt go higher than 90°C with any OC.

Well technically you COULD push up to around 100C, but I think the general consensus is to keep it less than 80C (more comfortable)

Also, if your temps reach to the mid 80's during Prime95, that's fine. That's such an outlier in terms of real world scenarios. You'll never be pegging your CPU like that during games, so you're perfectly fine as long as it's stable.

Ok im stress testing different voltages at 4.5ghz now
Whats the quickest way to test stability? I dont want to run hours of prime95

and I picked 1.21v in BIOS but CPU-Z is reporting 1.236, whats wrong with this? my vdroop is set to extreme, by the way

What is my actual voltage then? 1.21 or 1.236?

Ok this is annoying. Even if I change vcore to 1.205 @ BIOS, when I stress test CPU-Z reports it going up to 1.236

How can I fix?

BSOD @ 1.205 BIOS even though CPU-Z said 1.236 but no BSOD at 1.210 @ BIOS when CPU-Z reported same 1.236v

there's nothing to fix. Certain programs are going to show different voltages. They're all going to be within the same ball park. As long as you have a safe voltage and safe temperature, there's nothing to fret over.
.05 Volts here or there aren't going to kill anything.

Yeah well I got BSOD at 1.210 anyways :/

With BIOS setting at 1.215 and Intel Burn Test doing 20 runs at the "high" stress level, core temp says the maximum any core reached was 83 on Core 1, with core 0 being 75. So temps are 75-83-81-76 at peak peak peak load during 20 runs of IBT high stress level at 4.5Ghz/1.215v with H100i only on 'performance' fan setting

Can I consider this both stable and good temps?
