Hello, I'm wanting to know how my overclock stands up. I'll list my components and my screenshots I have screenshots showing Prime95, Coretemp, and CPU-Z. I'm just not sure the temps are where they need to be I had just applied arctic silver 5 so maybe the curing period hasn't finished.

Intel Core i5 2500k @ 4.2 Ghz

ASRock Extreme4 Gen3

Corsair H100i w/ SP120's Quiet Edition

Corsair Vengeance DDR3 1600 (2x4GB)

Gigabyte Windforce 3 GTX670OC

Corsair AX850 PSU

ASUS XONAR DX 7.1 Sound Card

ASUS Blu Ray Writer

Fractal Design Define R4 w/ 3x AF140's rear, and 2 front both quiet editions

Overclocking Settings

CPU: Load Line Calibration; Level 2 (there are 5 levels)

All Cores Set: 42x

FIxed Voltage: 1.275 on test one and 1.26 on test 2 (have gone down to 1.25 and its stable will do a 60 minute prime95 test later, 1.245 and 1.24 were unstable causing blue screens)

CPU: PLL Voltage 1.7v

Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Enabled
CPU C6 State Support: Enabled
Package C State Support: Auto

EDIT: I believe my fan situation was causing my temps to be higher then they needed to be. The front fans were pulling air from the case not pushing air in. Since my case has a door it wasn't do anything by pushing the air through the front so I turned them around so it was pushing air into the case That changed things pretty significantly.

Linpack is designed to generate the highest possible heat output. I haven't used this particular stress test software but I have been using IntelBurnTest to determine the maximum possible CPU temps. I currently have 3 Intel builds so haven't found a need to use anything else other than Prime95 and IntelBurnTest. I will pickup OCCT this weekend and test it on my 3770k and let you know what I find.

Also, any reason why you are running this test on a laptop?

And here I thought you were just trying to utilize the laptop as an inefficient heater...

You should expect temps to be 5-10 degrees higher when running a linpack test.

Also, I assume that your 78 degree max was with OCCT? If you are running at a cool 50-55 degrees during Prime95 at 4.2 then I would recommend pushing the system further since you are well within a comfortable temperature range.

Lastly, always reset Core Temp when running different tests to obtain an accurate reading for said test unless you plan on sitting there and observing the test for the full duration.

I set my max temp limit to 80 C. When I go beyond that point OCCT will turn the test off. I haven't tested since I reoriented my fans yet but prior it would go over 80 within the first few minutes of the test and I was getting quite frustrated. At Idle I expect 35-36C and with my Max temps while testing I get above 70 somewhere maxing out in the 74-76 range. So I'm not sure how much further I can really go. I'm fine with my 4.2 ghz oc I'm a bit afraid to go much beyond that I've done 4.4 ghz in the past and got that to pass but I had to use Loadline Calibration 1 which is the extreme calibration I can't recall the volts. I have a handy dandy oc notebook by my desk that I jot notes down on.

Sorry, I assumed your case had a windowed side panel. Put on the side panel to obtain optimal air flow to run the tests now that you have a proper intake and outtake fan setup.

And make note of the house temp yes? And you want me to use linpack yes? I'll run the test for 30 minutes on each and report if I get a fail on either.

For reference I watched this video which gave me the idea to use OCCT because I was new to overclocking and TTL is a very informative youtuber who knows what he is talking about.

Ambient temperature was 76 Degrees F
Okay so I've spent a good portion of tonight working on this. OCCT really frustrates me quite honestly. So I've come up with a few conclusions and I'd be interested to know what you and maybe others think. Every time I ran OCCT at least the recent version 4.4 the temperatures I was receiving would sky rocket whether it was with linpack or without it it just ran up so maybe something is up with the program I don't know I was getting temperatures around 85-90 max and I had turned off my failed test option to see where it would go. After that I went through and tried the offset option and I didn't like that either with prime95 or occt because it was bouncing my voltages all over the place and that wasn't okay with me. So I finally came back to prime95 and I went back to 1.25 volts and I re read the asrock guide for ASRock Sandy and Ivy Bridge Boards http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition# and I realized I had forgotten to setup prime95 to do something. I had not selected these options for the test which really helped in the end because my temperatures were FAR better. And I also saw by looking at my pictures of prime95 that it uses AVX yet I didn't have any issues within prime95.

here is prime95


here is OCCT: Pay special attention to the CPU Core temps.

There are reports that OCCT 4.4 has issues with reporting accurate core temps on their forums. This seems to be the case with you as well since two of the four cores seems to have substantially lower temps while two peaked at 90. I am not seeing Core Temp up with your OCCT benchmarks so can you run both programs to confirm if this the case for you as well. Also, take screenshots when the benchmarks are running to provide more accurate information :)

The picture you provided isn't very clear and cores 3 and 4 seems to have maxed out at 55 and 53 degrees according to that OCCT screenshot. What temps were you seeing in core temp?


Edit: is that 91 or 81 for the 2nd core in core temp? That screenshot is illegible.

You have to control +.

in OCCT: Maybe this screenshot is more clear I took it using their snapshot utility.

CORE 0: 73 C
CORE 1: 80 C
CORE 2: 78 C
CORE 3: 75 C

In core temp
@ the time I stopped the test it was



Core temp 0:74
Core temp 1:81
Core temp 2:77
Core temp 3:74

The resolution is low so it comes up blurry when I zoom in :) Either way, it is a large disparity between the earlier 85-90s you were observing in OCCT

As I have said earlier, I haven't used OCCT yet so it is difficult to gauge relevance of these figures. I would recommend trying an earlier version of this program or another linpack stress test.

I would be able to provide better insight after I test OCCT this weekend.

Okay sounds good I'm going through intel burn test man this test is intense man :X I'm not sure how many times you are supposed to run it but it defaults to 10 so I'm going with 10. I'm nearly done with 5 temps max out at 85 on core 1 but other than that it seems alright. Still pretty damn brutal man. I'll post pics when its done. Last test took 189 seconds.

Here you go :) Test was successful there is no way this is what I'd experience all the time but the test seems to be successful. Hopefully the curing period for my arctic silver is finished soon. Also, I don't have super fast running fans mainly quiet fans so I expect my temperatures not to be SUPER low but at the same time I think my 4.2 Ghz overclock should be fairly obtainable. If I was doing anything beyond this say 4.4-4.6 I would need a different case perhaps or stronger cooling fans that weren't quiet edition.

Are you not already running at 4.2 GHz? Since only a singe core maxed out at 86 on the burn test, you may be able to push up into the 4.5 range and still have a stable 24/7 overclock.

See how far you can push the clock speed while maintaining voltage at or below 1.3V

I am running at 4.2 Ghz. I don't want to push much beyond that. I want to keep my temps max under 80 so I may be just at a point where I'm comfortable. I've gone up to 4.4 before and I know I can probably touch 4.6 but I don't want those high of temps. And I know that if I got near 1.3v my temps are going to increase.

Also, yes its a 24/7 overclock I hear with the 2500k that clocks beyond the 4.4 range the 4.5+ mark starts to really take a toll temp wise.

Does this make sense or am I looking at it wrong? I mean I have a good cooler its possible that my temps are high yes but my temps will hold at the higher clocks and volts.
