Cpu overcloaking HELP

Post » Thu Jul 16, 2009 5:43 pm

Hey guys,
I got a AMD Phenom II X4 955 cpu and now I want to overcloak it.
I got a Scyte Mugen 2 cooler, Link : http://www3.hardwareversand.de/articledetail.jsp?aid=25731&agid=669&lb

I guess I need to go into my bios and do stuff there, I got Windows 7 32 bit.
Could somebody please tell me how exactly I get in my bios and what I should do there and maby what I should overcloak and howfar.

Btw I got a 530 powersupplie.

Thanks, sorry for my bad english...

It's different on some systems - on mine to get into the BIOS you press 'delete' as the computer is booting. Before the PC gets to loading windows.

In there I changed the FSB to increase the CPU clock taking my CPU from 1.8 to 3.0ghz. It may be different for your CPU. Type "overclocking Phenom II X4" into Google, there will llikely be guides online. Guides like that usually give an indication how far you can take your CPU. Once clocked run some tests to make sure it's stable. Something like Prime95 would do.

You get into the Bios by pressing "delete" on startup. Then you can overclock your processor by raising the multiplyer and the Front Side Bus. Processor clocks are determined by this:

Front Side Bus X CPU Multiplyer = Core Speed

Make sure you get stability testing and monitoring programs like AMD OverDrive and CPUID Monitor... Also get CPUID to make sure your settings have been entered correctly. For the Phenom 2, you want your core temp on the cpu to be at 42C or lower or things get borderline too hot.

Increase your clock until you see crashing/stability issues or if the testing fails, then you raise the vcore in the Bios and try again.

You can find several guides online to help you with overclocking.

I have gotten my Phenom II X6 1075T up to 3.6GHz with nothing more than two voltage bumps up to 1.33vcore, and changing the FSB from 200 to 240, and I am on the stock cooler getting 41C temps. I have been attempting to hit 3.7 GHz but that has been proven to be problematic so far... I have tried tinkering the voltages of everything except the CPU-NB one with no success... Probably needs more of that voltage then. :) I heard AMD processors love to eat away at those voltages so raising that should allow me to hit 3.7 stable, my only worry is it will get hotter than I like. :)

Good luck!

Btw, is it true that i7 920's run hotter than most other CPU's on average? Im getting around 43C with stock cooling and no overclocking at idle. Im using CoreTemp to check the temperatures. A heads up would be appreciated :)

Intel processors have a different architecture than AMD and are therefore better at running hotter. The maximum coretemp you want to keep at with Intel is usually <72-75C, while with AMD you want the maximum coretemp to be at <42C

To answer your question, Intel processors are much hotter than AMD counterparts and are built to withstand the heat also.

I used to get 70C running my Core Two Duo E6750 @ 3.4GHz, and I'm currently running a Phenom II X6 1075T @ 3.6GHz with temps only at 41C. :) Meanwhile, I had a custom Heatsink for my Intel processor and my current AMD processor is using the stock heatsink. :P

I usually get 22C at idle for my AMD processor, which is the ambient temperature for my house.

Look up some dedicated groups on the internet. http://www.overclock.net for instance.
