Ok, noticed something weird.
I've been using LtMatt's bios (1.175 voltage with slightly aggressive fans). I decided this was too loud for my liking so 'borrowed' the settings and created my own fan profile, then flashed this bios onto the card.
The strange thing is the card now runs a lot cooler??? Playing sleeping dogs the card peaked at about 62, but the fans only reached 39%. On the other bios I was getting temps up to 70 with fans on ~70%
Do the fans draw more power when on high, and this could then contribute to heat? That would seem counter-productive.

Which bioses were you using?

Hmmmm, I believe it was this one:
http://www.sendspace.com/file/g8e0fl

I think it was the second one you originally posted (925/1200 with 1.175 voltage). Looking back at the first page I can now see there's a lot more :)

I used it as the basis for my own ones, used all the same settings but just changed the fan profile back to the stock profile. Somehow it seems to run a lot cooler and quiter.

It could just be me :)

That's the one im using now. Works well for me.
 
Just purchased 1 of these to use in second system. For a £180 with the free stuff it comes with, it is pretty good value. I almost bought a 7970 Matrix Platinum over the weekend which looks really good as well, but even at the reduced price I struggled to justify it to myself, considering I already have 2 7970's with waterblocks.
 
Just ordered the HIS iceq 7950 for crossfire (finally).

Did you load the profile you mention and then overclock it LtMatt?

I still havn't tried these profiles on my iceq x2, not sure if they will work or not with the model being slightly different. Also i think the board on the x2 is a 7970 board as i have to buy a 7970 water block for it if i want to watercool.

Wow these at £175 I'm tempted to sell my 680 and get two of these, how much increase in performance would I get? I game at 1080p

Think the 7950 and 680 are reasonably close performance wise, so 2 7950's with good scaling could see u get anywhere form a 75-90% performance improvement over your 680 I would say.

In saying that if the system in your sig is still your system then you may find your 750 bottlenecks 2 cards. I certainly know my I7 920 @4ghz bottlenecks my 2 7970's significantly.

Tell me about it, I started a thread in the CPU section and in the end the conclusion was don't upgrade yet wait to see what happened with games in the next few months due to the new consoles.
 
I have switched to bios 1. And went to run heaven. It crashed but I noticed the volts where different for eeach gpu.

gpu 1 1250
gpu 2 1175 so I went ttoreflash the cards.

atiflash -p -f 0 Matt.rom shows device Id 0
atiflash -p -f 1 Matt.rom also shows device id 0

is this right

Updated the OP with a new bios with increased TDP.

Results are very promising.:)

New bios for testing:

925/1250MHz Non Boost 1.175v -INCREASED TDP FROM 130W TO 173W-CrossFire users-ulps can now remain enabled with no performance loss!!!

This is a new bios that Matt and myself have been testing, further feedback welcome-especially if you are running CrossFire.

Matt's found you can overclock further before you need the power limit.

My own testing has achieved slightly lower voltage for my 24/7 clocks:

Before-1100/[email protected] +30% Power Limit

Using this bios-1100/[email protected] no Power Limit adjustment required.

It's looking like this is the bios to have for full featured CrossFire(ulps enabled-shutdown of secondary card in idle).

Please try it out folks and leave feedback.
 
Question, i occasionally get a stutter or a drop in FPS when playing any game from CSS- Bioshock infinity.

Am i right in thinking thats the boost thing doing that? and if i flash it to the new bios it wont happen anymore?

Cheers

Yes John. Read the OP for the two different options available to you. The best longterm option is the bios flash using the bios tommy just posted a few posts above us.

ALL HIS 7950 ICE-Q users should flash this bios. Forget about the other ones, this is the best!!

As Tommy has already stated with this bios you can overclock and use ULPS. No throttling. You can leave power limit at 0% and still run a decent overclock like 1100/1500. @1.175v and your card will not throttle. However eventually you will need to increase the power limit. So if you go much higher than that use it.
 
Sorry to be a pain LtMatt but could you check with Kaboom (or point me in his direction) if the bios would work on the HiS iceq x2 7950 boost version of this card.

I think i've asked before but my memory is not that great (sorry).

Or do you think i'd be safe enough to try it anyway? i can allways flick back to the default bios i guess if it goes wrong :)

I bought one of the iceq 7950's on offer yesterday so ill be flashing that but it would be nice to lower the voltage on both as i imagine it is going to raise my temps when i have 2 in my case.

Try it. The only reason it might not work is if the card you have has different memory timings. If your card has Hynix ram it won't work. It won't hurt to try though as you have a spare bios. Just be sure to backup your working bios first so you can flash it back afterwards if needed.

If it doesn't work you'll need to ask Kaboom to create you one using your stock bios.

Here are pics from flashing my cards.

Are they correct.
