AFAIK all 7850 can run @1050 on stock volt.some has passed over 1100 on stock volt. if u wish, u can unlock the volt otherwise try asus gpu tweak. but the fact is amd has increased the volt and decreased the core frequency by default.

First hand at overclocking Asus HD7950 Direct CUII

Here is my first hand at overclocking my HD7950 Direct CUII. I reached this overclock very easily and I'm sure this 7950 in my hand can go beyond 1000 MHz very well... will try tonight. Tested the current overclock by playing Witcher 2 EE with ubersampling on and ultra settings for around 1 hour. The FPS gained in the game was 20 (it ran for 50 FPS throughout 1hour of gameplay). GPU temp was hovering around 65 degrees with "AUTO" fan settings.

Tested On -
CPU - Core i5 3570k
Cooler - CM Hyper 212 Evo
Mobo - Asus Maximus V Gene
RAM - G.Skill Sniper 8GB Kit (F3-12800CL9D-8GBSR) 1600MHz
SSD - Corsair Force 3 Series 60GB
HDD - Seagate Barracuda 1TB


GPU Info -

GPU : Radeon HD7950
Manufacturer and Model Name : ASUS HD7950 Direct CUII 3GB


GPU Stock Speed : 800 MHz
GPU Overclocked Speed : 950 MHz
GPU Core Volt : Stock


vRam Type : DDR5
vRam Stock Speed : 1250 MHz
vRam OCed Speed : 1250 MHz (Stock)
vRam Volt : Stock


Cooler : Stock (Direct CUII)
Bios Version : Stock
Software Used for OC : Asus GPU Tweak

^^ The highest possible OC I've seen on Guru3d is 1200 Mhz - you have crossed that limit - congrats !

@ the_conqueror - tery with 1050 Mhz core speed and if possible bump up the mem speed too.

@ mandarpalshikar - play with mem speed too.

These Tahiti & Pitcairn Southern Island chips are overclockers delight it seems :)

Here is my second attempt at overclocking my HD7950 Direct CUII. I reached this overclock very easily once again and got 1000 MHz for GPU. OCed the memory as well this time to 1450 MHz. Tested the current overclock by playing BF3 for around 1 hour and running 2 iterations of Unigine Heaven & 3DMark Vantage. System was totally totally stable without any artifacts. GPU temp was hovering around 64 degrees with "Manual" fan set to 75%.

P.S. - Dont go buy overall 3DMark score... see the GPU score. My CPU score this time around was low since I had disabled turbo boost in BIOS.

I wont push this thing further as I still need to enjoy this Beast (got it last week only). I'll tinker with voltages only after doing due research (say after 1 or so month). Till then this is my highest clock.

^^ Great going .. looks like every HD7 series ( staring from HD7770 ) gaming gpu can go over 1 Ghz easily.

^^ then you need to play with vocre settings but your card has no option to do it, right ?? so 1 Ghz is what you can get from the HD7850 you have.

@topgear.no it can easily hit 1050 without unlocking core clock. what i had read from overclockers.uk forum is, many card has different default volt settings. some has 1.08v, some has 1.13 volt and has 1.21v volt as default. my card is 1.13v as default.
@the_conqueror. what tool are u using? i had msi ab. goto settings->general,under compatibility properties check unlock voltage control and unlock voltage monitor and press ok.
