7950 lovin and OC's thread

MSI afterburner initially didn't allow me to clock very high either. I then restarted the pc a few times and the overclock range suddenly increased, I have no idea how

Where is the ASIC quality anyway? I thought it was in GPU-Z but maybe I'm being blind.

EDIT: Nm, found it. Mine is 67.3% at stock.

Where do i Find this ASIC quality?

Thanks

I had to edit the config files in order to be able to clock more. It seems a bit stupid when you're far more likely to fry your card with too much voltage and you can enable voltage control in the settings with a mouse click

Right click the top of the GPU-Z window and it opens a menu.

You have to drop those two driver files into system32 and syswow IIRC to get the higher clocks.

What is ASIC quality? Mine's 75.9%, whatever that means.

I also think that on the current drivers, the cards limit in Heaven is around 2050. I can't get mine above 2020 ish, well, not without increasing V a lot higher, but as above, it's past the point of diminishing returns!

MMmm says not supported on my card lol
edit
Haa was tring to read Intel mines at 73% at OC 1005/1400 that good?? lol

trixx says i need to disable ULPS to overclock =/

What about this, I've just installed an i5 3570K at stock, did another run.

Puts me 12th overall in the league table.

and is the highest scoring 7950 I think.

psychodil · 31 May 2012 at 07:02

Just did a run at 1225/1450 at 1.24v. Got 2056 points but had a few artifacts towards the end, gpu hit 80 'C on 100% fan, oops. Maybe my cooler isn't mounted very well but think I'm temp limited at this point until I fit my antec. Wonder if the ivy bridge helped piemans score at all?

pieman109 · 31 May 2012 at 08:52

I think I've found the max of the card:

1255 core/ 6000 memory/ 1.315v/ fan speed 100% cpu @ 4.2ghz

I'm not going to try higher as I think more voltage makes no difference and quite frankly I baulked a bit at putting over 1.3v through the card

psychodil · 31 May 2012 at 09:05

Lol, nice effort. How did you get more than 1.3v through the card? Afterburner only goes up to 1.3v. I may need it when I water cool, thanks.

When I installed me 3570K yesterday, I had to reinstal some drivers and AB had defaulted to the low level clocks again, so I loaded up Trix and used that, works a treat too, voltage goes way beyond 1.3v

psychodil · 31 May 2012 at 09:34

Hmmm don't think trixx gave me voltage control, will have to reinstall and try again tonight. Was it the latest version? Thanks.

jakejacob0 · 31 May 2012 at 10:14

How do i disable ultra low power saving guys?

Veco · 31 May 2012 at 18:01

I seem to be stable on 1100Mhz Core, 1600Mhz Memory on 1137mV which seems pretty good for VTX3D HD 7950 =D
I'm going to have a quick play with 1200Mhz core, see if 1250mV will work if i'm a lucky one.
Edit: its close, took slight more juice on 1200Mhz to avoid artifacting. I'll stick with 1100Mhz.

I don't get any voltage control with version 4.3, only the power control settings. I've not tried it myself but I think 4.1 will let you increase the voltage from what I've seen from screenshots.

Well I am very happy with my 7950. I have the VtX3D X-Edition, coupled with a 3570K and so far so good. Stock results are good but overclocking.. so far i'm at 1200/1600@1175mV equating to 2101 Heaven 3.0. Temps are bit up due to the warm weather, fan profile on auto keeps temps under 77oC@65% speed. Seems that my voltage is a bit lower than others, I think I have a keeper

pieman109 · 1 Jun 2012 at 00:48

Just installed the 12.6 betas and did another suicide heaven 3.0 run and got:

thast at the identical settings in me previous run.

EB_Prophet · 1 Jun 2012 at 00:54

Interestingly enough I have been seeing jumps of 71 in score (from 1000-1200) with every 50Mhz increment on core so far. If this pattern stays true and I try a 1250 run which should be achievable seeing i'm not even at 1.2v yet, I would be at 2172!

Boo: Can't get 1250 stable even at 1250mV, And I don't wanna go higher. 24/7 1100@1075mV/1600 seems like a good place.

1250 core on mine needs at least 1.3v
