7970m...how high can it overclock?

[HopelesslyFaithful]

Title says it all how high can you OC it without voltage changes.
Then how high can you overclock with voltage changes...anyone got an idea?



BTW I thought i had more than 3 line sin this post....weird maybe another thread....ah it was the 680vs 7970 i had updated.

alrighty, here are the threads ive come up with in my subscription folder that are somehow concerned with overclocking the 7970M in various machines, sorted by the date of the last post:

@ stock voltage on a dell card, for me, its 1ghz core 1.5ghz vram

Geo was able to take his 1020mhz core, 1.55 ghz vram

For everyday, i game at 950/1375. however, even the stock 850/1200 will produce very playable fps in every game out there

The clevo cards typically come with slower vram, so those cards may not be able to pump up the ram as high...and although pumping up the ram past 1100mhz in the 6990m didn't make much of a difference in benches, i'm seeing huge differences going from 1200 to 1450mhz. The 7970m can make use of the additional bandwidth

Got benchmarks in my sig, don't think this card can be overvolted..

EDIT - It can be!

That's just SICK Geo....SICK!

oh i asked somewhere else and no one answered the dell m17x r4 has the 7970 and what not but what mxm board does it use? Will i be able to upgrade to the next card or two? I would plan on upgrading my graphics card 2 models down the road if i can

also why can't you up the voltage?

[Karamazovmm]

it uses mxm 3, dunno about the variation though.

regarding upgrading in 2 years its up to nvidia, since they are the ones that make the mxm standard.

[SlickDude80]

i personally thought the 7970m used the mxm 3.0C standard

however, according to this source:

2GB GDDR5; AMD Radeon Mobility HD7970M (Wimbledon); 1280 Stream Processors; 256-bit; GPU 850MHz; VRAM 1200MHz; MXM 3.0b; 100W

Currently, the bios on the 7970m is locked...so you won't be able to up the voltage on it. Its also protected by the drivers which prevent it...so says the author of RBE

now we were able to extract the 7970m vbios using a bootable USb and ATIFlash, some values were editted but at the time we were too chicken to flash it back.

Maybe geo has more insight...did you try something recently Geo?

Benchmark tessellation load modified by AMD Catalyst driver, result invalid. Check your video driver settings. (What is this?)

^^^ that just means its with tess off

I know but it's still invalid .
