Some 50's can be flashed with a 70 bios, but it only runs the clocks/voltage/fan profiles, it won't unlock the shaders and on the earlier Ice-Q' Boosts, the dvi iirc was disabled.

But the 50's on 7970 pcb and the memory timings are much better from what I heard.

Currently running 2 7950 IceQs, just wondering, will all ports on the back of the card still work with this modded BIOS? As I run EyeFinity and pretty much need all the ports. I know some of the BIOSs disable one of the ports.. just cant remember which

Cheers

Yep, this is like an update to your current BIOS. It only modifies your BIOS, everything works much better then on boost

MSI AB works with this BIOS

This bios is the greatest thing since sliced bread.

Currently running 1093/1563 rock solid stable at 1.155v and memory at 1.6v

Yep!

1070/1500 core VDDC 1.1v-1.125v, temp 60-61c my ASIC 79.8% :cool:

I uploaded the 1070/1500 low voltage profile, are you running this one? or...

EDIT

What ASIC was your new card?

IC3 · 15 Jun 2013 at 14:00

On BOOST BIOS I went to 1204/1601, mem stock.
I didn't overclock the card on the new BIOS, I might play with it today.

Does anyone actually read what I wrote?

Can this bios be used with other 7950's ie my Gigabyte.

That's strange, are you sure that your card is BOOST and not Turbo? Because they behave very similiary, but they are different...

Oh yea I have the Turbo, not the Boost

EDIT : I have the BOOST, not turbo

Try this HIS 7950 Non Boost BIOS with 800/1250

Remember to clean old drivers & OC tools and reinstall them.
There's also a link to the lower voltage BIOS that kahboom gave me to test out, over 3 days with this BIOS and no problems.

LtMatt, What does Zero Core do anyway?

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

Jarrod said:
How do you explain ZeroCore Matt?

Also, these BIOSs seem to unlimit my power control to +50

Is that safe?

+50 is an option for overclockers that overclock on good cooling for Benchmarks. I would recommend using +20/30 with 24/7 clocks

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

Trixx

Kerazee said:
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 :rolleyes:

IC3 · 18 Jun 2013 at 22:34

Kerazee said:
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.

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?

hey, iv got the gigabyte windforce 7950 with asic quality of 63.4, voltage locked @ 1.25V. Can i use this? I have the 2 switches on the gpu, so if the update failes i can just switch the switch and everything is ok?

Temps are maxing out atm at 70-75C so its not that hot, but i dont know, i just wanna play a little . Increasing even 50mhz on this cards freezes whole system, so sitting at 1ghz..

I give a link to kahboom's thread, the first link is to his thread so please read before you ask...

ViRuS2k, What ASIC is your card? My card is 79.8%, 1070/1500 the voltage from the BIOS (the lower voltage one, gave a link on 1st page) is 1.093-1.115v. Temps around 59-61c fan speed 57-61% depending on the temp.
If you could upload that BIOS here it would be great. After 3-4 weeks when I comeback will give this a try.

EDIT:

Last days the temperature in the Sun was 46-47c and in the shadow it was 35-37c. It's been a week now with these temps, I hope this will chanage. I can imagine what temps my PC would run during weather like this...

skyjawa said:
Bit of a pain as I have 1 card with 82.3 ASIC and another with 69.3 lol

I guess I should use one that's best for the lower quality so slightly higher volts.

Which one would be a good one for that as a starting point chaps?

The BIOS is like an update to your standart Boost bios which adds on couple features, the voltage depends on what ASIC is your card. You don't have to do anything except flashing to have a fully working HIS card without any unuseful junk...

IC3 · 28 Jun 2013 at 16:54

skyjawa said:
Yeah so I think I probably have to aim for one to work with the lower ASIC (my newer card ). I'm thinking the bios Ltmatt is using will prob be the best to try first?

Nope

lettuce said:
Ok so all I need to do is flash that rom and I'm good to go, or do I need to do tweaking after. Is the 1150 rom at a locked voltage then, if so is it lower than the default bios?.

Just flash the card and it will come up with the clocks as it is changed in the BIOS so you don't have to run any overclocking tools. You should be more then fine with 1140/1500 clocks as you have the gelid cooler

Also BOOST didn't allow you to change the voltage as it kept constant 1.25v and as tommy showed the screenshot the terriable jumps in performance...

Could a moderater change the title to *****7950 (disabled) BOOST bios thread****

Thanks

Flashed my card last night and really pleased with the results. I'm running the MSI 7950 TFIII BE and went for the 1070/1500 BIOS. Now I'm getting a voltage of 1.181v according to Trixx. My ASIC is 67.7 so this is about what I was expecting.

Much better.

I've pushed the core speed a bit further and managed a (seemingly) stable 1125MHz on the same voltage. Pretty good considering the max I could hit was 1140MHz @1.25v using the boost BIOS.

So just confirm, is the voltage locked with this new BIOS?

Good to hear

The voltage is not locked you can change the voltage right up to 1.30v (I would recommend not going above 1.25v on air) you also have the 50+ power limit raised for better OC stability etc. What sort of temps are you getting?

I'm using the HIS 7950 IceQ [disabled] Boost BIOS with 1070/1500 lower voltage. My card ASIC is 79.8% and the voltage I see in OVerclocking tools when I press reset is 1.115v and GPU-Z or Trixx shows my voltage as 1.098-1.1v. The temps didn't go above 64c with fan fixed at 60%
So if you card is higher ASIC you could probably lower the voltage down a bit.

lettuce said:
With this modified bios cn I still use MSI afterburner program?

MSI AB is glitchy with modded BIOS, I use Trixx 4.4 or you can use a mod trixx.

Jamezinho said:
Regarding the power limit setting, what do you suggest?

I normally run +20 but is there any need to go higher than this?

24/7 clocks then no.

IC3 · 30 Jun 2013 at 14:36

lettuce, MSI AB for monitoring is absolutley fine.
skyjawa, Use the BIOS given in the thread here or kahboom's thread. The BIOS you used was specially made for Matt...
Again if you have problems with the BIOS please write to kahboom, hes a human as well and we all sometimes make mistakes. There might be a small mistake in the code, PM him and explain the problem. That's why I said to do some testing to say that the BIOS works 100% correctly without any issues.
Remember about making a backup of your stock BIOS and flashing BIOS update meant for your card!

Yeah, I've since moved on to the other low volts bios you posted. Currently have it running at 1020 and 1450 seems ok, haven't tried it at the stock settings in game yet. Every time I've tried to push my memory over 1500 though I get issues in game but it will bench at 1600, no matter what bios.

lettuce - the gigabyte 7970 bios works with some cards, mine were fine but others had issues. Also disables the HDMI socket.

He has MSI 7950 OC BE, not HIS. That BIOS didn't work for me or either LtMatt, some other users said that it didn't work for them either.
If you are having problem with the lower voltage BIOS download the normal BIOS and theres a profile with 1000/1400 clocks.

lettuce, write back to kahboom tell him your problem and he will fix it. Some BIOSes are different from the other, I tested the BIOS I'm currently using and there were 2 small mistakes which were fixed in no time :cool:
