*** Official 7950 Ice-Q Owners Club***

I've installed Windows and overclocked the cards to 1100/1400 but seem to be getting a really low 3DMark 11 score of 8984!!??

I've pretty much done the following:

1) Installed Windows 8 64 bit and installed all updates, drivers, programs etc. I'm running Cat 13.10.
2) Ensured Xfire is enabled - it was.
3) Disabled ULPS
4) Used HIS cool to OC to 1100/1400
5) Ran 3D Mark 11
6) Saddened by low score.

I've got my 4770K at stock at the moment - could that be why I'm getting such a low score?

Also, check these GPU-Z screenshots - is PCI-E 1.1 correct!? Render test reports differently.

Have you got the power line at +20%

The card might well be throttling at 1.25v stock voltage and core overclocks of 1100/1400 per card. I found the card would throttle around that point. At this stage you can either use the power line hack tommy posted to increase it to 30% instead of 20%. Or you can flash the bios i posted in the 2nd post to remove the boost part of the card, lower the stock voltage and add the increased power line limits to the card.

installed the bios provided thanks matt and it works incredibly well have a fire strike score of 10700

just wanted to no if that's about right for 2 cards crossfired?
running 3570k to overclocked to 4.1

Glad the bios worked for you Andy. Its the best long term solution. Now you have removed the boost part of the bios. No more 1.25 stock voltage. No more core clock fluctuations at high overclocks, even with +20% power line. Most of all you don't have to do the power line hack each time you install a new driver.

Looks about right Andy, Here's my score on firestrike with 13.10 driver.

cpu at 4.8ghz
7950's @ 1125/1600

12660 with AMD Radeon HD 7950(2x) and Intel Core i7-2700K Processor
Graphics Score 16376
Physics Score 12213
Combined Score 4784

Frame pacing on.

Next up, as generally it's the boost version most are using, it runs on a higher 1.25v default, there has been a few workarounds by making profiles in AB to lower stock voltage, the best way is flashing a custom bios-as it comes with a dual bios switch your sorted there.
Are all these cards supposed to be 1.25v default?

MSI Afterburner is reporting my card as 1.125v

Though I'm doubting this a little now as I did a quick overclock the other day and card ran 1200/1500 no problems, haven't tried any higher yet. That was with the Power Limit % at 0

Msi afterburner does not work properly with HIS 7950 Ice-Q cards. You might think it does, but trust me it doesn't. It will report incorrect values regarding voltage.

If you want to use msi afterburner you need to flash the bios i added in post 2.

Otherwise as instructed in the OP you should use HIS version of afterburner. ituro is linked in the OP and is the HIS overclock tool. That will display correct voltages and allow you to change voltage for the card on core/vram.

You should always run the card at +20% power line as well. Your card probably seemed stable because it would have been throttling with the power line at +0%. Your core clock would have been decreasing. Using an overlay will enable you to monitor such behaviour.
 
Ah, thanks. :)

Sorry to be a noob but whats the best way to monitor for this fault or should I just apply the fix anyways?

The best way would be to use msi afterburner overlay and enable core clock monitoring display for both cards. Make sure you've disabled ULPS before this if you have crossfire so you can monitor the second card. Clock the card up to 1125 or higher on the core, leave voltage at stock 1.25v. Run Unigine Valley and look at the core clock dropping = throttling.

The best fix is the bios flash, assuming your card can run the memory at 1400. The next best fix is Tommys power line hack. The only downside of that is you have to do it for each and every fresh driver install and you have to do it twice if you have two cards. I'm working on getting a lower clocked bios from Kaboom so that we can have a bios with a lower stock voltage, stock clocks of 925/1250 and a permanent power line of +50%. That will be the best solution as everyone could use that safely.
 
Have you got the power line at +20%

The card might well be throttling at 1.25v stock voltage and core overclocks of 1100/1400 per card. I found the card would throttle around that point.

Or you can flash the bios i posted in the 2nd post to remove the boost part of the card, lower the stock voltage and add the increased power line limits to the card.

Cheers!

I'm about to do the BIOS flash now, one thing though. I've followed your instructions but my files look like this:

Have I done something wrong!?

Mine only had the two files; atiflash and matt.rom; worked fine.

I have this flashed now and I have reinstalled my drivers/programs but some programs (Tomb Raider and 3D Mark) are freezing on me where they weren't before.

I re-applied the same, pre-flash tested overclock of 1100Mhz core and 1500Mhz memory, using the HIS iTurbo program. I can see no problems with high temperatures or maxed loads, when using MSI the O.S.D. + HwInfo64 providing additional readings.

Any suggestions?

cheers for the reply im very happy with that as im aslo running a 1440 korean monitor

Not sure mate. As long as you formatted the drive first so it was blank then you should be ok.

Mine only had the two files; atiflash and matt.rom; worked fine.

Hmmm no idea. If you want you can try my 24/7 bios instead?

1100/1500 are stock clocks with voltage of 1.175v.

Btw Kaboom has agreed to create me a new bios with stock clocks of 925/1250. Once its done i will post it here to share and we can all use that then just overclock as much as we desire. It will also have its own custom fan profile % that matches the temp of the card.
 
Did it this week in anticipation for rome 2 and bf4. With my 7850 i played at 1080p ultra shadows high and msaa off. I got 60-70fps avg but saw drops in intense scenes to 35 occasionally. 7950 avg 80-100 added 2x msaa and it may have dropped into the 50s once or twice but a much more stable avg and it means with bf4 hopefully will just remove aa to get 60 in ultra! My 7950 is at 1100 core and my 7850 was at 1050.

Thanks mate, very helpful.
 
I'd love to see these iceQ (Or similar) coolers being available on a wider range of cards, like Nvidia ones.

I am in love with "Blower-style" coolers, but they'er loud as heck if you wanna stay under 70c. Silent at under 80 but throttling.
