On Intel Burn test and prime 95 the highest I hit is 85..
Good deal, temps still seem to high. Have you tried running the vcore below 1.25v for that 4.0 OC?
To be honest I wouldn't want to see anything over 70cish under load, 85c is to much.
Think about getting a second fan for push/pull on the H50.
What motherboard are you using? Knowing that can help us give you some pointers on the settings in its bios to change.


Edit: add screen shot of my settings/ vcore and temps.
CPU fan speed is my pump on the H50 rpm
Chas fan 1 is one of my fans on the H50 rad
Chas fan 2 is the stock fan that came with the H50 on the rad.
All being force to 100% speed by bios.



Edit2: IntelBurn Load test / Stress Level High
Note: vcore change under load in CPUZ.



Also Note: I'm on a bench setup, so temps would be higher if in a case.

Hm I swear my vcore is manually set to 1.25 (tried 1.20) not stable. But in CPU-Z it says core voltage- 1.056 and then changes back and forth to 1.044 very now and then...?

Just ran intel burn and hit 71 max (maybe my TIM settled in some and the room cooled?)

That's probably idle voltage on the vcore since it will lower the clock & voltage while idle.
Check CPUZ while it under a load & see what it shows as vcore.
Still wondering what motherboard you are using with this setup?

* I tested at 100% load. Still at 1.056 core volts max.

Here is my CPU-Z info.
post #37 of 47
CPU-Z doesn't show the correct vcore on the Gigabyte z68 boards. You'll have to use EasyTune or something like that to get a proper reading until they update CPU-Z if your running a Gigabyte z68 board.

Adding to the posts above, even when I didn't have a push/pull my temps never got that high.

2. Major BIOs tweaks got my vcore down to what it is now, 1.25 for 4.0 isn't too bad, but still sort of hot.

3. As for overclocking your chip, the best advice I can give you is what I did in my BIOs to get my chip to run at 4.5 at 1.29..

-Internal CPU PLL Overvoltage = Enabled
-Real-Time Ratio Changes in OS = Enabled
-Intel Turbo Boost Tech. = Disabled
-CPU Enhancement Halt (C1E) = Disabled
-C3/C6 State Support = Disabled
-CPU Thermal Monitor = Disabled
-CPU EIST Function = Disabled
-Multi-Steps Load-Line = Level 6

-Vcore manually set at 1.295
-Downclocked 2133 RAM to 1866
-Manually set RAM voltage to 1.505 (Regularly at 1.500)

Before I did all this I had to run AT LEAST 1.43 Vcore to get my chip to run at 4.5Ghz, after doing all these tweaks, I got a little over 50% drop in my Vcore, making my temps a lot better, and a peace of mind for myself, and my chip.

Give those settings a try and see if I can get you up there with less vcore and just check your temps and post back. After you get your chip stable, I'd focus on a Push/Pull setup for your H50 and see if that gets your temps even lower.

@N3kko what case or are you using a case?
If your 2600k is a pretty good chip it should be able to do 4.2 at that 1.25v maybe more.
Mine does 4.4 @ 1.28v under load 1.268v & just over 1.3v for 4.5Ghz 1.305v under load 1.29v.
Just trying to give you a idea what it might take to do other clocks.
Of course not all chip & hardware yield the same results.

Edit: you may want to look at forcing the pump & radiator fan to a faster speed in bios.
This can lower your temps quite a bit if its not already set manual.
Seeing Dustin has a Gigabyte motherboard he should be able to help you with those settings
better than I can since I haven't owned a p67 or z68 gigabyte board. So I don't know my way around that bios.
I normally set mine to 100% or full speed, the fan nose doesn't bother me. lol I like it as cool as I can get it.

Followed you settings and I dropped my vcore down to 1.20. But now my temps are ideling around 43.

Try setting the H50 pump RPM to full speed in bios also set the fan on the radiator to full speed in bios "if its not already" That should drop the temps a few C.
