Hey, This is my build. I'm wanting to overclock my CPU just want some guidance!

CPU: AMD Phenom 965 Black Edition 125W
CPU FAN: Coolermaster Hyper 212 Evo AMD Socket AM2 AM2+ AM3 AM3+ FM1 Intel 775 1155 1156 1366 Processor Coole
Motherboard: Asus M5A78L-M/USB3
RAM: 16GB DDR3 RIPJAW G.SKILL 1333MHZ
PSU: Corsair 650w Bronze Certified
GPU: HD 6850 1GB
HDD: SATA
CDROM: Not a clue basic DVD Re-writeable

All core temps are idling around 34c to 37c

Min 33c on all 4 cores and max on 40c on all 4 cores.

I only want to do overclock it to about 3.8ghz

Thanks :)

They're pretty much similar. Go into your BIOS and disable any CPU fan Power Saver modes, C1E, CPU Spread Spectrum, or any similar modes that will power down your CPU when it isn't in full use. Then, raise the CPU clock reference multiplier until you hit 3.8. It should be x19. Then exit and save your settings. Download Prime95 if you don't have it already, and download CPU HW Monitor and CPU-ID.

In CPU ID, your CPU should read 3.8 Ghz at all times. If it doesn't, go back to BIOS and find the setting that is modulating its speed. When it is always running at 3.8Ghz, then run Prime95 blend test. Then look for the temperature reading of the CPU in CPU HWMonitor. Keep it below ~60C on max load. If your CPU runs for several minutes (I go about 30) without overheating or failing in Prime95, then it is stable in my book.

If it goes above 60, you have some options. If it was stable but above 60C, you could try lowering the voltage in tiny increments in BIOS. This can lower the temp, but it is more likely your CPU will become unstable at full load in Prime95 with a lower V. Likely, you won't be able to lower the V with any OC active. If you are below 60C, you can keep pushing if you want. If you are below 60C but you are getting failures, you could raise the V until you become stable, as long as you stay below about 60C.

Ok, Just been playing cod for a couple of hours didn't break a sweat was around 37 the whole time.

Will do this tomorrow thanks!

Ok, Just turned the ratio up to 19x but now the temps won't show in HW Monitor. Should i reset them back?

Just set it back to auto and it still won't the temps now. Any ideas?

I accidentally selected unlock cores, could this be the problem?

Fixed it all, ran it for 20 mins on blend. 49 on max load on all 4 cores, is that stable enough?

Cheers :)

All I needed to change was the Power saving on the fans(couldn't find any) and the multiplyer for the CPU? Not the voltage or anything?

Thanks!

Sorry if this is late.

No, you don't need to mess with the V unless it isn't stable in Prime95. (If you fail a test). If you fail, raise the V by the lowest amount possible and then try again. The more V the more heat and the more heat the less life length of your CPU. If you are hot, and stable, you could lower V by the lowest possible amount and do that until you aren't stable. Most times at stock V you should get 3.8.

Not a problem, It's been running fine on 3.8ghz for a few days. One thing that I've noticed not sure if this happened prior probably did but on my Motherboard I have tempature readings under
TMPIN0
TMPIN1

The TMPIN0 is running around 10c hotter than TMPIN1, is this normal or?

Btw it ran up to 49c on Prime95 for 20 mins, When i play games and I'm streaming hits around 44 - 46c is this fine?

Thanks :)

Hi Ryant704

I am running the same CPU, my specs are:

AMD PHENOM II 965BE C3 @ 4.2GHZ
CPU Cooler: Cooler Master V6GT
Case: Cooler Master HAF 912 Advance
MOBO: Gigabyte 990FXA UD3
RAM: 16GB (2x8GB) G.Skill RipJaws 1600MHZ @ 1360MHZ
PSU: Cooler Master 700w Extreme Xfire/SLI Ready
GPU: HD7950 ASUS 3GB OC
HDD: Sata 2 x 160GB

You can definitely get more than 3.8GHZ out of that CPU, although every chip is different, most can achieve minimum 4GHZ.

My temps are 32C on standby and 50-52C on load and testing with Prime95.
