i5 2500k and asus p8z68 overclocking help!

post #1 of 11
Thread Starter 
So i have decided to finally overclock my cpu!

I have read through some guides and watch some videos and i am right now running a 4.3ghz overclock. I did this by changing my bus speed to 103Mhz and my multiplier 42x I set manual Vcore, and DRAM and i have the Vcore running at 1.28V and the DRAM running at 1.4V. I have not changed anything else and i have intel advanced speedstep technology enabled. I am running prime 95 with core temp and i am reaching max temps of about 66C max on core #1 (it seems to run much a little hotter than my others.) on my coolermaster V8 cooler. These are actually much better then i was getting before by about 5-7c hotter when i had a Vcore of 1.3V.

First are these voltages and temperatures ok? Or do i need to change them? Also after these changes the CPU will no longer step down to a lower frequency when not in high use aka idling it just stays at 4.3Ghz or suggestions to make it step down?



My list of settings:
Bus Speed: 103.02Mhz
Multiplier: 42x
VCore: 1.28V

Updated Settings:
Bus Speed 100Mhz
Multiplier: 43x
Vcore: 1.232V

Update #2:
Buss speed 100Mhz
Multiplier 45x
VCore 1.285

Update #3
i changed my fan orientations and now with 4.5Ghz i have 70C max on my hottest core.

The blck should stay at 100. No need to change with sandy and not to safe either. You should be able to get your volts down abit more maybe. I have mine at 1.248 right now with 42 multi. http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition Also try this too. Lokks good so far

Thanks for the suggestions, I just change the blk to 100Mhz and my multiplier to 43x and my volts are now at 1.232V im running prime 95 ill see how it works out. If its stable then i am going to try to get like a 4.5Ghz overclock maybe even a 4.7Ghz

I got 4.5Ghz stable. But my load temps are about 70C on my hottest core. Any tips to get it lower? Im trying to get the voltage down but i dont think i will be able to get it much farther without a BSOD

70C is as hot as I would go in day to day use. What cooler are you using, and what volts for 4.5ghz?

With a base model aftermarket air cooler (something like a hyper 212+), 4.5ghz is likely as high as you are safely going to be able to go at those temps. To lower temps a tiny bit, you can always try reapplying thermal paste, replacing it with better thermal paste, or putting a second fan on the cooler you've got (if possible). Really though, to lower temps you will probably need to upgrade your cooling setup.

Is it 70C during stress testing with Prime95 or IBT? If so, that's completely fine. I wouldn't worry about it until it strated creeping up toward 80C in those tests. Normal gaming and such isn't going to get within 10C of Prime95 or IBT temps, so 70-80C in those programs is completely fine.

I am using a Cooler Master V8, I am at 1.285V for the 4.5Ghz i cant get it any lower without crashing when i start prime 95. It seems to be stable at 4.5Ghz and 1.285V. I may try some new thermal paste and see if that helps. I re-configured where my fans where and now i get max around 68c. I am also having a problem i can not get the CPU to down clock when it is idling, it just stays at 4.5Ghz the whole time. Did i do something wrong in the bios?

Thanks

Those temps are fine, I wouldn't stress about it.

Couple things could be stopping the downclocking. You need to enable C1E and EIST in the BIOS (Auto is sometimes disabled when overclocked, depending on the board) and you can also enable C3 and C6 if you aren't using offset (they sometimes cause trouble with offsets).

You also need to make sure your Windows Power Plan is set to Balanced. If it is set to High Performance, that'll stop downclocking also.

I don't know exactly what you've done in the BIOS, assuming you just changed the multi and manually set your voltage. Just so you know you can do screen captures of the BIOS screens by putting a USB flash drive in and pressing F12. A 2500k will do 4.5ghz, most people use this for day to day. I have my 2600k set at 4.5ghz with a little lower voltage, but my temps don't go above 70c. As above have said games don't really max out your CPU anyway so even if you're running in the 60c range you'll be fine. You can attempt to lower your voltage to find out what the threshold is to keep it at 4.5ghz. I don't recommend trying to get up to 4.8ghz but it's completely up to you.
