I7 2600k overclock help.

[Maurice]

hey guy's I got a little better cooler, so I thought I would oc some. My temps get to about 68C, so I don't know if I can push it any further. I would like to get 4.5. I tried 4.5 with everything you see, and it fails.

Here are my bios settings, and was wondering if I need to change anything.

What kind of cooling are you using?

A few suggestions:

Set CPU Enhanced Halt (C1E) to Disabled

Set C3/C6 State Support to Disabled

Set CPU Thermal Monitor to Disabled

Set CPU EIST Function to Disabled

Set CPU Vcore to 1.36

Also, I'm not familiar with your motherboard, but if possible, set Enhanced Speed Step Technology to Disabled.

[Maurice]

Cooler is a Silenx pc cooler EFZ-120HA5

Not the best, but better than stock.

[Nagoshi]

You'll need more vcore to go higher than that speed, at which point you become bottlenecked by your cooling.

You might want to try messing with the CPU overcurrent protection and see if your CPU might be held back by the board throttling it down due to the current going over the default value.

You could also try enabling CPU PLL overvoltage and drop the PLL voltage to 1.6v.



Another thing you can try, this board can OC using two ways, first one is how you are doing it right now, the other is to leave the CPU multi at stock, but enable Turbo and set all 4 values at your OC. You can also set the power and current limits to something much higher that way, and I think you can even keep Speedstep and all the power saving stuff enabled using that method. I havent tried it personally but both showed a working OC at 4.9GHz on my 2500K using SuperPi.

[Maurice]

Ok I'll try this a report back.

Additional Comment:

I guess I will have to settle with 4.3 for now.

BTW: I have bios version f2, and saw they have up to f8 now. Should I update, or just leave it the way it is?

[Nagoshi]

I have F6, Ive heard people were having boot issues with different F7 versions. I dont know about F8.

Why cant you go higher? Unstable?

[Maurice]

I can go higher, but temps were reaching like 83c, and I'd rather not run it that hot.

Like it is now it hits 70c loaded. idk why, this is a descent cooler.

Additional Comment:

another reason I was thinking of updating bios, is that it is 10c off of cpu temps.

it says the cpu is running at like 31c when real temps and core temp says 41c.

For comparison, I have a 2700K overclocked to 5.0 GHz with vcore 1.40. I am using a Corsair H100 water cooling system. Even when it's a bit too warm in the room (like it is today), my max temp at full load is 62c. Idle right now is 37c and the motherboard (asus p8z77v-deluxe) temp is 31c. My temps can vary quite a bit, depending upon the temperature in the room.

If I was you, I'd go ahead and flash the latest bios to your motherboard and see if that makes any difference for you.

[johnerz]

I'm currently @ 4.456 @ 1.344 v on a Full H2O rig and folding 24/7 at 52/53c ambients arount 20c so I'd say your to hot and would also flash the bios to see

[Maurice]

I have not updated my bios, but I may.

Here are some pics and load temps. Will this be ok to leave this way?

[Nagoshi]

That's not even using LinX? temps are a bit on the high side then, but so long as it doesnt hang around that when you use your computer you will be fine.

Tried re-seating your cooler? How did you apply the TIM?

[Maurice]

When I use Linx It only reaches 58C. I found using prime it stresses it more for some reason.

I need to buy some AS5 and try reapplying and stuff.

[Nagoshi]

Did you hit the max memory button?

[Maurice]

no, I didnt. that much of a difference??

I'll try it out.

Additional Comment:

I tried it with max settings and still only got to 70C

I'm gonna by some as5 tomorrow and try that.

[DC]

I don't know why you need such high volts.

When I was using a Corsair A50 - this is a $10 AR Heatsink mind you! - I was able to pretty easily get 4.5 using about 1.28v.

My load temps with the A50 were about 67/68C.

I'd definitely say get some good thermal paste in there, it'll shave a few degrees off, though it'll need a few days/a week to set to attain the best transfer of heat.

Also - what sort of case are you using? Does it have good airflow?

I'm really surprised by your results given I have such a similar system spec, or at least did.

[Maurice]

I got the as5 I will try that. My case is just a basic one, and the airflow was not the best. I have changed a little, 120 in the front, an 80 on the side, and a 120 blowing out the back. it has helped a little bit, but am waiting to put the as5 on. I am hoping that will give me more headroom.

[DC]

It might help - I just did a new build and have a 6 month old Antec 902 II case just sitting about - may do a HTPC build with it but if you're interested I'm in So Cal too mate.

[Maurice]

What would you want for it?

[DC]

I don't know - still in the box and all - I'd say $50?

Don't know if I'm supposed to im by now, but where in Southern ca are you?
