Hi all :) Got a question-or a problem i guess. I run auto-clock on AMD O.D. and that bad boy goes to 18.5 multiplier HT ref. 205- Mem frequency 409-voltage 1.425 and puts my Phenom II 720 up to 3.8Mhz and i can run the AMD O.D. stability test forever. As soon as i start Prime95 down it goes. I tried the same settimgs in my bios but wouldnt even boot. I am at 17.5 multiplier-stock voltage of 1.325 and im at 3.5Mhz at 53c load and can run Prime all 24hrs no problem. Am i topped out or do i have more room to go a little higher? I have tried going to 18x and went all the way up to 1.425 volts at .025 ticks (cuz thats how my mobo goes) with no luck. Can anyone give me a hand ? And i dont mean clapping !

yeah, that sounds like the top. What cooler are you using? I hope its not stock, although with an overclock like that and still those temps, good job. *gives him a hand*. Other than that, you can try to keep increasing the voltage, but be careful. IMO 3.5 is really pretty nice.

Thank you last resort. I am using the Arctic 64 Pro. I tried setting my bios to what the AMD Overdrive went to which was 18.5x---1.425 voltage----FSB 209 which put me at 3.8mhz-----but couldnt run Prime for even 30 seconds. Should i be able to just bump my multiplier and voltage up to get it a little higher? i would like to get to 3.7 and be able to keep it stable. Any suggestions would be great.

Personally , I have had a really disappointing experience with amd overdrive , it does nothing but crash my pc and freeze itself etc . my advice is use the mobo instead

and , I find it better to keep the multiplier at 15 and up the fsb to whatever , and I reckon 1.525 volts is a little high ,
I reckon you should reign in a bit on 3.8 , I think 3.6-7 is about as far as you can safely go on air

i would be happy at 3.7----i guess even at 3.6------- so maybe if i drop multiplier down to 16 maybe and up FSB wouldnt i also have to up my voltage ? And for some reason i dont have much luck in my bios.

If your OC is not stable then you need to up your voltage. For your reference my voltage had to be 1.525 V to OC to 3.7 GHz using the multiplier only. It only needed 1.45 V to OC to 3.64 GHz using the FSB only at 260 MHz.
