Hey there I have decided after a couple of years of having my rig its time to tinker with it a bit.

I have always been interested in overclocking and followed a couple of tutorials on youtube to try and get 4.5ghz through Bios Method.

Only problem is within 10 seconds of p95 and real temp I get like 92 c on 100% also OCCT stops the test as soon as high temps happen.

I was wondering what I am doing wrong? Is it the Freezer 13? Even default 3.3ghz gets upto around 80 c after a while of p95 100%

Do I need to fiddle with voltage?

I would be happy with any form of safe overclocking as long as I seen an improvement of some sorts.

My spec is:

Intel i5 2500K
Asus p8z68-v lx
750W CX Builder Series 80PLUS Bronze PSU
Freezer 13 Cooler
2tb 720rpm0 Hd Barracuda
Asus 770 GTX
64gb SDD (Operating system)
8gb 2x4gb Corsair Blue Vengeance Low profile 1600
Coolermaster Elite 335U Midi tower

Hopefully the saviours of Toms Hardware can help out

Thank you very much.

The 6 and 7 series motherboards are kind of where overclocking got simple, as long it is the CPU has a K. With that Motherboard your using should be able to get the temps lower. though i would not recommend an extreme overclock. If you have it set to offset voltage go into the UEFI and change it to manual Voltage. try a bit lower 4.2.maybe 4.3Ghz then get the voltage as low as you can

Note: the higher your CPU frequency the motherboard when using offset will try to compensate and add more voltage accordingly. I have seen my CPU go as high as 1.2460v at 4.1GHz.
Sandy Bridge gets better temperatures then Ivy Bridge and Haswell. Also you can put a bit more voltage to the CPU once you start to hit 4.7-5.0Ghz.

I have the same board and cpu, and if I push mine, I can get 4.4g. When I push mine to that, it will run in the mid 70's on p95 or intel burn in. I keep my voltage pretty low and just keep tweaking until I hit my max freq with the voltage at or below 1.35v. Use the manual voltage setting in bios/UEFI to play with the settings.

Some 2500k's o/c better than others, but I think you may have a couple of issues: 1. That case (I have one for my wife's rig) does not offer very good airflow. I have my wife's (Athlon X4) set up at 4g with a Cooler Master Hyper 212 and three fans - two 120mm intake and one 120mm exhaust. 2. It also sounds like you may have a TIM problem. The Freezer is very similar to the 212, and should be performing better IMO. I would suggest re-doing the TIM - be sure the cooler is snugged down well.

Thanks for the reply guys so my problem could be mostly through Voltage?


I have no idea what so ever how to muck around with that

Any help would be great!

I would try removing the cooler, cleaning it and the CPU and reapply thermal paste.

When you remove the cooler, inspect it very closely. Which method of thermal paste application did you use? How does the distribution of thermal paste look? It should be evenly distributed on the CPU. Not necessarily full coverage. It is OK for the corners to be uncovered by the paste. Also be sure that there is not too much paste used, as evidenced by excessive paste oozing out around the edges of the CPU.

How are you controlling the fan speed of your CPU cooler? Does the fan speed increase to max as core temps get hot?

Try a stress test, like OCCT or IBT, with the side cover of the case removed. Does this improve (lower) CPU temps at all? If it does, this would indicate poor airflow through the case.
