Fx-4100 Overclock help

post #1 of 14
Thread Starter 
Hi guys, this is my first post so go easy on me.

Just got my rig yesterday and picked up this Fx 4100. My mobo is is an Asus M5A78L/USB3 and Im planning on picking up a Radeon HD 6870 sometime this week.

My main question is overclocking this cpu, and to narrow it down, how?

I have the AMD OverDrive software downloaded and coretemp and my temps on idle are around 39c.

Any pointers to start me off in the right direction would be appreciated!

For starters, welcome to the place.

What is your heatsink.
What are load temps like (idle temps are worthless)

Thanks!

I only got the rig on Friday so I am still using the stock fan/heatsink that came with the Fx.

Can you recommend a program so I can find out my load temps?

You can Use Prime95 To Stress Your Cpu for about 2-5Mins then tell us what the Load Temp is biggrin.gif

*EDIT* I just Looked up your Motherboard and I see that there is no Heatsinks On The Vrm's, So you may only want to overclock Abit.

Okay so just done a 6 Minute stress test on Prime 95. Used CoreTemp to monitor my temps and the highest it got to was 55c.

Im not too fussed about how much I get out of this, Just curious about the whole thing and wouldnt mind having a little play with it.
post #6 of 14
I'd say at those temps you really do noy have much of a margin for overclocking. Is 55c your cpu temps or core temps?

With the stock fan and that mobo, you are going to be servilely limited on what you are able to do. I wouldn't touch the OC until you get a better mobo and cooling.

your motherboard isnt an overclocker. you could maybe overclock a bit, but not much. also, dont use a program, go into your bios to overclock... you might want to put a heatsink or a fan over those vrms.

I think I will leave it at that then until I sort some more cooling out in there! Thanks guys!

You should be able to do 4.2ghz on stock volts.

Try seeing how far you can get with out touching the voltages.

Also guys remember that the stock cooler is a downdraft style and thus cools the VRMs to some degree.

See if you can get a fan blowing directly on that area and that should help.

Finally this board actually should be fine up to 140w with some cooling: http://www.overclock.net/t/946407/amd-motherboard-vrm-information-list so I wouldnt worry about catastrophic failure like the MSI boards.thumb.gif Worst case scenario it will throttle CPU speeds.
