AMD Athlon II X2 Overclock...

So my board makes it really easy to overclock. Did it for the first time this morning going from 3.4 to 3.57 (using the 5% increase option). Booted fine and operated fine. Then I got nervous and changed it back to default. I have the option to go all the way to 5.00ghz or so but I highly doubt that is possible. Whats the best way for me to know where I can safely OC to?
 
It's all trial and error. You slowly bump up the multiplier in the BIOS and reboot until Windows eventually BSOD's. Then you just bump it down again slightly and burn-in test the stability with Prime95 while observing the temps with something like CoreTemp.
 
clquestor, I have pretty much the same setup as you: Win7 / AMD Athlon II X2 Regor 270 @ 3.4GHz / ASRock 760GM-GS3 / CORSAIR 1600 8GB (2 x 4GB) / using on-board video. How did you overclock it?

F2 when booting gets you right into bios...scroll over the cpu/overclocking tab and enable overclocking...from there you can choose to bump 5% at a time (or all at once but that is NOT recommended)

Voltage options are also below...I was able to OC to 3.7 and ran prime95 without issues...then when going up to 3.9 I ram prime95 and failed. Changing voltages might have helped that but thats where my knowledge ends...so I knocked it back down as it was more of an experiment than a necessity.

Keep in mind I am using an aftermarket heatsink with copper heat pipes, not sure how the dinky AMD stock heatsink can handle OC.

Let me know how you make out!
 
I tried the 5% and 10% settings this morning, have not prime95 it yet, but it seems to be very easy to overclock. I have an ARCTIC COOLING Freezer 64 Pro CPU Cooler with Arctic Silver that works pretty well for limited overclocks. Two things: One, with everything on default HT is only at 1600, I can change the multi to 9x (1800) but not 10x (2000), 10x is not available in Auto or Manual. What is up with that? Two, the chipset seems to get pretty toasty on this MB, so extra cooling may be needed in this area too when overclocking. Do the two passive heatsinks on the MB get pretty warm on your MB?
 
I have been testing and have this setup up to 3.9GHz (244 x 16) stable. CPU voltage is set on 1.45 volts in the bios but both CPU-Z and SpeedFan report it as 1.424 volts. HT/NB are on x8 (244 x 8 = 1952) for both. Memory is at 813 DDR3 1626. Prime95 tested for 12 hours without errors.

I have not tried it any higher yet, but have a feeling it will take more CPU voltage then I am willing to give it without a lot better cooling...only time will tell.
 
nice nice, and yes its trial and error, just whatch the temps, and yes prime95 is oke but this program will be better for stabeliti, linx with avx.
prime maby needs 12 oure if you want to be shure, or 24 oure, linx with avx needs 1 oure withe the mem on all.
but a little warning the temps will go higher then with prime95
 
What I did not say and should have, I used IntelBurn Test V2 first. I did 10 passes of it using max memory and it passed and then I did Prime95 for 12 hours. It got a bit warm, 52 C for IntelBurn Test and 48 C for Prime95. My Arctic Cooling Freezer 64 Pro 92mm CPU Cooler did a very nice job keeping it cool. Unfortunately this is a cheap MB and they did not give much room for a large CPU cooler, so upgrading will be hard and therefore extreme overclocking might be out of the question. Where there is a will there is a way.
 
Currently I have everything back to default as I have no need to OC right now...just wanted to mess around with it. I'll be upgrading some components eventually when they release Doom 4 specs.

Its probably the biggest that will fit on our board. My ram has standard black heatsinks and this cooler just barely fits. It took a couple weeks to set properly and I used arctic silver but now my temps are super cool especially with the new case and a side intake blowing directly on it.

I actually used the Alpine as my last cooler on a different Athlon x2 (the 240) and I thought that was really good for the money.

At what point did you need to change cpu voltage with this board? Or have just just been upping the mhz by %?

And I haven't check the passive heatsinks at all.
 
At 3.8MHz I still had it on the default voltage of 1.4 volts, it reads 1.375 using CPU-Z. After that I needed to up it to 1.45 volts that reads 1.425 in CPU-Z. I think I might be able to lower the voltage to 1.425, but it is running cool now and so I'm going to keep it where it is for now. I have a 140 mm case fan blowing on the passive heatsinks. This has worked great keeping them cool. I am doing everything manual now and not using the auto overclocking.
