****7950 (disabled) BOOST BIOS thread****
- Thread starter IC3
- Start date
Its a his 7950 official bios compatibility issue, if you try to up the voltage no settings take effect.
its like the bios is blocked with msi even though the hardware is sound and works with another bios though breaks hdmi.

This will explain all.

Just did a test on my pc and my 7950 crossfire setup as well as my whole base unit, fans, fan controller, 8gb ram, ssd etc is using 70 Watts at idle.
While im using my pc one gpu is completely shut off, fan not spinning using zero electricity. When i leave the computer idle, after 5 minutes my monitor goes into standby and the first gpu shuts off as well. You can tell this as the fans are not moving. The second you move the mouse the first gpu powers up. The second you load a game the second gpu powers up.

I'm probably very close to you power draw at idle.
7950, 5 fans, fan controller, SSD 120gb and 750gb HDD, Soundcard, 8gb ram and i5 2400 with energy saving turned on
+50 is an option for overclockers that overclock on good cooling for Benchmarks. I would recommend using +20/30 with 24/7 clocks

Zerocore effectively turns off a second gpu completely so it uses no electricity when you're not using it. It will also turn off the primary gpu if your monitor goes into standby mode, so long as you have ULPS enabled.

Probably.
I have all power saving features enabled on my motherboard, cpu and gpu's. I'm just happy to have a xfire setup that only uses the same electricity as a light bulb when my pc is sitting idle, which it does a lot. Our electricity bill is high enough as it is so as antony worrall thompson says...

Oh god I'm tired, the reason I typed "explain" was because I was watching the video you posted haha, I meant how to you enable xD

It should be enabled by default providing you have not disabled ULPS, disabled a screensaver and or have your monitor power off to sleep in windows power control after 5-10 minutes.

I can't seem to get AB to work with the low voltage bios posted earlier, or any of the others, what is everyone else using? Trixx? I don't really want to use the HIS tool. It is a real shame that RadeonProv does not support voltage adjustments

After a bit of fiddling, it looks like AB does work, I have managed a 2d profile of 500mhz/800mv(core) and 700mhz/1600mv(mem), with a 3d profile of 1125mhz/1200mv(core) and 1400/1600mv(mem).
Only really been playing with core clocking at the moment to find its limit, how safe is it to take these HIS cards to 1300mv on the core using the stock cooler?

Not sure, But I wouldn't clock it over 1200mhz on the stock cooling
Will be added to my loop within the next 2 months, I was just not sure what the stock cooling is capable of,
Currently at 1125mhz and getting to about 72ºC with the auto fan profile, suppose I should probably leave it at that until it goes under water.
Caporegime
What voltage do you need for that clock and what is your asic?
for 24/7 on air I wouldn't push the card further then 1100/1500.
I use fixed fan profile and the max I get is 59-60c at 1070/1500 1.1v 79.8% ASIC
What kind of WC setup are you getting for your system?
Associate
Forgot to come back to this, been doing some more stability testing and at the moment on air the sweet spot seems to be 1100mhz @ 1200mv (about 1180 under load via GPUz)
My asic seems to be the lowest I have seen on this forum @ 53.6% will be good when I have it under water hopefully, just not quite there yet.
It will be when I re-build the existing loop 2x240mm rads (one already), D5 (have already) with top (top to be decided on), Swiftech micro res (have already) and some make of full cover block (probably EK as they seem to be the best price/quality at the moment although I would love a swiftech FC block), cpu wise, depends if I can re use my existing block on a haswel build that I am planning.
Can someone edit the his low voltage bios for me please. for my current setup
the asic for my 2 cards are : 83.2% and 83.1%
-----------
Both HIS ICEQ`s 7950s.
-----------
current bios im using @GIGABYTE 7950 bios @
current msi afterburner clocks are :
Default Bios Clocks are :
1: 1050v @1000/1375
2: 1144v @1120/1400
3: 1169v @1165/1450
------------------------------
this is the default clocks of the low voltage his iceq bios for my cards
1070/1500 @1.100v
could someone modify me 2 his iceq low voltage bios`s both with these clocks, thanks
1: 1070/1375 @1050v
2: 1070/1400 @1080v
cheers.
My cards or one of my cards has issues running 1500 as the cards freeze up for some reason , probably **** memory controllers lol
but for defaults i want the above clocks that way i can oc further with msi if i wish

Here is where you need to ask, politely.
