Will be going back to 4.5 on my 3570k... but I need some info on OCing GPUs... never done it before...

I will be running 7950 (OC Sapphire editions) in CF... any info would be appreciated... PM or post is fine

hm

i'm on a real crap rig so i'm not expecting much of an oc but i'd like to go up from 3.6ghz to 3.8-3.9ghz on my fx4100

i upped the multiplier and set ht/nb to 2200 mhz as opposed to the auto 2000 mhz, and cpu should be at a solid 3.8 or 3.9 (either or, depending on what i set it to) but it cycles from 3.3ghz to 3.9 on current oc during prime95, and caps at 3.7ghz if i'm not stresstesting it like that.

base clock 200mz, multiplier min x7 (1.4ghz), max 19.5, if not under stress it hits x18.5 multiplier, if stressed it goes between x16.5 and x19.5 (3.3-3.9ghz) and only those multipliers

any ideas?

not a software dude qq`

No go, restarted twice too.

Download MSI Afterburner (newest beta edition), download CCC newest beta edition, download Unigine Valley 1.0 or newest edition. Then go into AB and unlock voltage. Once voltage is unlocked slowly raise the core clock, I usually do +10 MHz each time, and run a unigine valley test on Extreme HD. If it passes without crashing the OC is good. Repeat the process until you can't OC any higher. Then move on to the memory clocks and do the same. When you finally hit a wall with both, then you slowly raise the voltage by a few mV. I do about +5 mV per test when raising voltage.

Your cards will require a balance between memory clock and core clock while the voltage allows it to stable. Don't forget to monitor temps and save the profiles as you go in AB. When your cards start hitting 80C you have reached the max for the 79xx series. VRMs for benchmarking supposedly can go up to 110C or more.

There are also a few tricks you can do to increase the performance of the OC. Crap that AMD throws in but screws it up.

Sugarhell has some good info on OCN: http://www.overclock.net/t/1360884/official-top-30-unigine-valley-benchmark-1-0/0_20

Though keep in mind he is a douchebag. Then again he is Greek so if I was Greek I'd be a douchebag too.

Undo force constant voltage, disable low level hardware monitoring for one. Not sure why your card is bugging out. You have a 6850 though?

6870 no clue either
Can't go past 910 without crashing.

could just be your lottery number

Just did that stuff Sushi but no luck.

Won't unlock the voltage? That is odd.

I feel like I just got a really shitty batch

/e.

I officially cannot go over 910 or it'll crash my BF3, so gaaayyyyyyyyyyy.
