925Mhz Overclock shooting for 1ghz later tonight! X4 840!!

post #1 of 20
Thread Starter 
Got my PhenomIIX4 840 to 4.125GHz yesterday STABLE 3 hours prime etc. Max temps are 57C full load and bumped the V's up one notch in bios. Today when I get off work I am gonna attempt to get 4.2GHz as this would put me in the club! Right now I got it to 265X15.5 on one step above 1.4275v(not at home so don't remember the exact v) I SURE hope I don't fry it lol. I had it to 4.2 b4 but that was unstable after 5 min of prime and I was using lower voltages. Even so a 925MHz overclock is pretty good for my. Chip as I have yet to see another over 4.0ghz. Ill post back here tonight on my progress! Wish me luck cause I sure need it...

57C is pushing it on those chips....lots of ppl say 55C is max stable temp....AMD says 62c for max temp. I would say your coming close to your thermal limit.

Can you crank your CPU fan any higher?

Nice job btw, it makes me think I can definitely push my chip further......weekend project!!!!

Well that is after hours of prime never gets over 40 in bf3 or doing anything else... does that matter?

Well I have h100 cpu water cooler. I have never tweaked the fan positioning in my case to see what's the best optimal cooling. Cpu and cpu block are lapped to 800 grit sand paper. That allowed me to get past 4ghz mark. Lap at ur own risk! Lol gl to ya man I can't see ur system cause on cell phone but gl anyways hehe
EDIT: is it worth going to cl 9 on the ram if it gets fussy just to get an extra 100mhz? I mean I know 100mhz isn't a big increase its just the fact of the matter that its 1ghz overclock and I'm sososo close. Addicted to ghz is an understatement for me I never could have imagined Id get so much joy in changing numbers and staring at temps and volts lol. Hey the first step is admitting that u have a problem. I use to not do very good things and have an addictive personality already so I guess ocing helped me in a way!

I would say change to CL9 and get your 1GHz OC validate it then go back to CL8 and 4.1 for 24/7.

Then your in the club and have the best performing machine you can have.

ie. I would say CL8 will be more beneficial then the 100Mhz. (However run some benches to make sure!)

Great idea! Is passmark performance bench a pretty reliable one? I don't want one that takes forever I guess I can do passmark and cinebench to see where I'm at. Who knows with that voltage bump I did last night maybe I can get 4.3? DOES IT EVER STOP?!?! B-)

The performance gain in superpi seems to be very minimal for me atleast. As far as wprime I've never tried but do have. Add me as a friend (I can't I'm on cellphone) and ill keep ya posted. What is ur rig?

Awesome wish I woulda been more educated on cpu's but I'm happy. Lame that I cannot unlock l3. Is there a pretty noticeable performance gain from that? Lemme know when u r gonna sit down and throw some more V's and G's on that beast hehe.
