i7 3820 - 4820 Overclock Club - Page 96

Someone used the auto-OC function? FOR SHAME. The door is that way! - - - - - >

On topic, I had 5GHz stable with 1.44v (125/40) booted up and worked just fine. Recorded the temps after a few hours of Prime 95, and they never peaked past 70c. I love the 3820 :3

I get 4.75 @ 1.38 and 5.0 @ 1.48 (stable for both). My temps are waaaay too high at 5.0 with my H100 though.

Also, that auto over clock function is a great way to do damage to your components. If you're not willing to get down and dirty manually, You should probably accept your chip for what it was sold as.

Freatica i just got my new rig...but Now...Who i can't oc my 3820 past 4.5 ghz? Whatever i do over 4.5 is shown as 4.3ghz on cpuid...tryed to go 5k @1.48 and cpu Won't work..tryed 4.7 at1.44v and it booted up... But when i try cpuid to verify the oc it shown a lower multiplier and a lower freq to 4.3ghz...i really wonder why

My actual oc is at 4.5 ghz and 1.33v temps at 48•C after 1 hour of stressing

Any Suggestion is welcome

Thank you

Crap..you guys are really making me scared about using the auto-OC feature on my Extreme4-M now. I'm coming from an X58 system and I was pretty competent with that but haven't read up much on X79 yet

I basically chose the 4.6ghz option, reduced the voltage and increased the multiplier to get this:

334

Any tips on the basic things I would need to change for a decent manual OC?
post #955 of 6491
those are actually some horrible Gflops you are getting.....i am getting straight 110 or above clocked @ 4.75
post #956 of 6491
I'm confused as all get out then... Something's amiss with my configs.... 289

I tried down-voltageing to 1.35 (at 4.75Ghz) to get under the "possible" voltage throttling barrier, that I read about, went down to 62 Gflops...

Any ideas / help would be much appreciated smile.gif Trying to get the most out of this comp for VM folding.

[EDIT] Apparently nothing. I tried going down to 1.33v, turning off all turbo options, and changing them to forced 38 multi @ 125 BCLK. I'm stumped ):

[EDIT2] I was curious, so I reverted to stock... And now I'm down to 50 GFlops.

You need SP1 in order to utilize AVX. Also make sure the Intel Linpack within IntelBurnTest is up-to-date.

4.6 stable looks like 125 bus 1.3v pretty easy. 37 Multi.. Anything else I should change

Thanks for the help mate! Seems that it was SP1. Installed it, and up to 105 Gflops @ 4.75GHz.

Thanks for that biggrin.gif Mine went up to104 now, but is GFlops actually a good way to measure an OC? Would using the auto-OC feature affect it at all?
