Final got a stable base system this weekend and decide to start a small OC.

Steps:
CPU Mult to 36
Vcore to 1.25V
Vdroop disabled
Internal PLL volt override enabled
C1E disabled
C3,C6,C7 Report disabled

Seems to be running very hot under 3Dmark physics benchmark, I turned it off once it hit 98C

Though it is still stable at the desktop or running a few apps.

Should I try to lower my voltage, is it set to high?

EDIT: Stock intel cooler, Evga Z77 FTW, Intel 3570K, 7770 GPU, inside a Haf Xb coolermaster

Couple things. First, that's too much voltage for 3.6 which is basically stock. Second, too hot with the stock cooler. You should go back in the BIOS, reset the optimized defaults, and then change the multiplier to 40 (or maybe 42) and then see what you get. You shouldn't need 1.25V for those speeds, so just leave it on Auto, and that should help keep the temps down. But with the stock cooler you aren't going to get very far - 40 may be your limit.

dropped it to 1110 and and kept the rest, went to 91C on 3Dmark11 phys test and 77C on the combined.

Just saw your post though, Ill return to stock optimized. Sounds much better after seeing what that did above.

UPDATE:

On stock it went 95C in the phys test, 72 in the combined test. Top Vcore I saw was 1.19 I'd say avg 1.12.

Idles alot lower at 45C on the stock + 40mult. On the later settings 60C at idle.

Is it possible to create my own CPU voltage curve?

UPDATE: would not boot at 41.

Going to 39 and trying the Evga tuning option and see if the 3dmark comes out any higher

Are you sure the cooler is on tightly? You might consider taking it off and re-seating it. Even with the stock cooler those temps sound a little high.

Well here are the results:

1st: Vcore 1.25, Mult 36
hit 98C and quit 3Dmark
2nd: 1.11 26
91C phys 77C combined
cpu score 7172 gpu score 3802 combined 3901
3rd: Stock + 40 mult
95C phys 72C combined
cpu scoore 7646 gpu 3626 combined 3861
4th: Stock + 41 No boot
5th: Evga tuning + 40
89C phys 68C combined
cpu score 7503 gpu score 3579 combined 3825

first two test ran about 65C idle on desktop
at stock ran 45C
put a fan ontop the case and run 41C

I do remember having difficulty pushing one of the pins through the MOBO when installing the stock cpu cooler, but I am sure it is on correctly now. I know I did not miss-seat the sink.

Did you apply new TIM when did the reseat ? If you have more TIM , take cooler off and see that TIM footprint is correct , if unsure post a pic and we will help out. On stock cooler 4 Ghz is going to be around the max OC.

Those temps are too high, id hold off overclocking until you get a decent aftermarket cooler. It doesnt have to be expensive, just half decent.

You can probably do 4ghz on stock cooling on that cpu, try putting everything back to stock and just change the cpu multi to 40 and change cpu vcore from auto to manual and put 1.1v in, or whatever stock vcore is.

For reference here the Vcores needed for my chip to pass Intel Burn test. The chip is delided so ignore temps.

Those are much better volts than average though, possibly because you have it delidded. New chips seem to be taking closer to 1.35V for 45~46.

FWIW, those GFLops seem low also. What settings did you use for that? My 2600K at 4.6 gets more than 100, you should be closer to 120 I think.

The GFlops is the same as most IB chips I have seen here on OCN. It is also on a measure of performance . Lots of IB owners have reported that GFlops improve with HT off oddly enough. The chip performance is not in doubt as I get 10.45 in Cinebench

I just ran cinebench 11.5 and got 10.11 points at 5ghz on my 3770k

Let me take this thing apart and ill report back

REPORT:

Reset the CPU, it was easier to put the heat sink on this time. not sure where the difficult lied the first time. Going to run a few more benchmarks and see what comes out

 

[SkeeterSkeeter]

The stock TIM

*reset with cooler master "high performance"





Ran to 4.2 Ghz semi stable and 4.1 stable stable and 4.0 super stable.
1.17, 1.14, and auto Vcore respectively

Going to see what 3D mark does at 4.1 setting.

EDIT: picture order

The TIM pattern looks a bit uneven , like uneven pressure on mount. Run IBT or Prime 95 to get max temps. Usually you will find normal usage would be 10 degrees less than stress testing. If you keep it below 85 on stress testing you will have your max OC on that cooler.
