****7950 (disabled) BOOST BIOS thread****

[ViRuS2k]

Same happened to me after a couple of minutes in BO2 with Matt's bios. But then I think that one has too high speed memory for my cards. Dropped it down to 1450 in AB and its been fine since. Crap memory

What I have found compare to the Gigabyte 7970 bios is the fan profile isn't aggressive enough for me with these modded ones so have to override with a custom setup - the giga bios was perfect as it was!

the gigabyte bios was perfection, apart from 1 minor thing, its destroyed your hdmi 1.4 spec port. apart from that it was awesomeness.

It only worked for 2 members out of roughly 12?
I've been the 1st person using this BIOS and it works for me perfectly fine. What are the problem's your are having with this BIOS? If you could explain it in more detail, then I'm more then sure kahboom will find sometime to fix these issues. (If there are any...)

EDIT:

Not enough aggresive fan profile is not really an issue as you can even set the fan profile in CCC.
Another issue is not really an issue as you flashed the wrong BIOS, that BIOS was made on LtMatt's request...
Any other `issues`?

that was the issue right there, the hdmi port stopped working, not displaying anything, not registering anything plugged into it, i think its because the bios uses a different modified hdmi port or slightly different hardware port, the only way he could fix it is to port the hdmi code from the official bios and overwrite the code in the gigabyte bios, but i don't think even he could fix that..and there would be no point in him porting over the voltages and clocks and fan profiles from the gigabyte to the official bios as he would run into a issue where by you couldnt change voltages in msi afterburner, where by the bios`s he is doing at the moment you cant change the voltage in afterburner but you can with the gigabyte bios....

its swings and round abouts no matter what way he does it, its what you can deal with that matters.

What I meant was that this BIOS doesn't have any issues when you flash the correct one and not someones BIOS made on request... Gigabyte BIOS bricked my card, the BIOS modded by kahboom works perfectly fine, I would even say better then the old non boost BIOS when 7950's where coming out
You can try to write him an PM on friday/saturday explain what you want nicely and who knows... Maybe he will edit this modded BIOS or Gigabyte 7970 BIOS.
But it's much easier for everyone to just set the fan how they want to...

EDIT:

What's the problem of using Trixx? When I game, I don't usually look at the temps every 2 minuets... That software listed above will show you what temps you got previously and also in Trixx you can also set a custom fan profile. If you don't like this BIOS then don't use it, use gigabyte BIOS...

the reason the gigabyte bios probably does not work for you is because your card is using none E5 memory meaning your memory is different to the people that can use the gigabyte bios, there memory does not reach 1500+
also your using trixx cause you cant use msi afterburner. and thats the negative about using official his bios`s...... and that you can only change voltage with trixx ect ect. but with cards that do work with the gigabyte bios they can use anything but there hdmi port stops working.

i have not found yet a bios that can be used with msi afterburner fully and have hdmi port working at the same time, and i have tested a lot of modified and official bios`s + bricking included to work out a way. lol

 

[skyjawa]

Well with the low voltage bios I've had some issues. Running BO2 after some time gaming it hung the system. Also I've got the problem back of failing to wake the screens up from sleep - have to reset/reboot. I'm going to try the first bios and see how that goes. Also cards seem to get hotter and require more fan.

Its a shame as on the surface this looks great but I may have to go back to the Giga BIOS, I don't need HDMI so don't care if its disabled. I can run at the stock bios without even touching a thing for near enough the same framerates.

 

[IC3]

Just look at this thread and if you are bothered check how many people are more then happy with it, if your card is low ASIC use the first BIOS listed.
Last question did you actually flash back your own BIOS and then flashed the modded one? I'm asking this question as this works like an update which changes some values in original BOOST Bios... For me the temp's droped by 4c fan does not go above 60% (CCC setup) with 1070/1500 1.115v. During BF3 I get temps of 61c max 100fps on bigger maps and during DM 120fps temp does not go above 60c. Before the temps jumped to 64-67c stock and with OC it jumped to 69c fan fixed 60%! I don't need to touch anything either as it took me 20 sec to setup the fan so it's not too loud and the GPU doesn't get too hot.

skyjawa, If you could provide us evidence of gigabyte actually giving advantage over HIS BIOS e.g. screenshot's of settings and benchmarks. It just seems not possible that a BIOS can give sucha an advantage with much lower clocks... Going back to memory I tried clocks on BOOST bios 1204/1601 and it passed 3dmark11, heavy heaven benchmark and metro. So I could probably reach that extra 50-100mhz but I don't see the need for it.

 

[skyjawa]

I'm not saying people aren't happy with it, I'm just saying that at the moment I'm struggling with the lower volts one. Haven't tried the other yet but will do. Unfortunately I don't have 36 hours in the day to do it all at once. Can only comment with my findings as and when I get to try them.

I'll flash back the original then apply the modified 1st one.

I posted a thread a while back about the other bios, not sure if there were screenshots but over the original boost bios running slightly higher clocks the giga gave the same or slightly more FPS with slightly lower clocks.

But that's irrelevant since it doesn't work for most people!

 

[Drangueos]

I think this is a nice thing, but the "default" clocks should be lower, not all the cards can do 1500mhz on the memories.
1000/1375 in my opnion is the sweet spot for a modded bios.

 

[Drangueos]

Another thing I have 2 MSI 7950 TF3... one is 59% asic and the other one amazing 52.3%

They need:
1.10V to 960mhz
1.15V to 1000mhz
1.25V to 1100mhz
1.3V to 1150mhz

So the bios with GPU clock at 1070mhz and 1.18V, probably will not work for me.

but my memories can do:
1500mhz with 1.5V
1700mhz with 1.6V
1800mhz with 1.65V

The lowest asic card is my primary card and it runs only 2/3C higher than the bottom one, so It looks like it can take more voltage with less heat.

If I use the lowest asic card at the bottom, the difference in temperature goes to 5/7C.

i have a ASIC of 60.3% on a Gigabyte 7950 and it cannot do 1000MHZ at 1.15v - had trouble with 1.20v (default 1.25v)

 

[IC3]

When your BIOS is BOOST there's no way you could have changed your voltage. It was constant 1.25v for others with lower ASIC cards this BIOS worked, try it and you'll find out as well.

EDIT:

Don't try any of the BIOSes provieded here, PM kahboom with copy of your BIOS and spend some time on testing (Valley, 3dmark11, heavy heaven, bf3 MP 40mins etc) the BIOS before using it 24/7. Best time to do this is weekend

Right - I've flashed back stock boost bios then flashed the his7950 one.

So benchmarking in Heaven Valley and v4 running 1070 1500 I hit 72 max on card 1 and 63 max on card 2 (card 2 is lower asic so need more volts but gets more airflow as at the bottom). I need quite an aggressive fan profile to keep those temps - roughly about 75% to maintain 72 degrees. Mine get hot

However this one seems much more stable with my cards, not not had a long gaming session yet.

But, a minor issue:

MSI shows no voltage - we know this, but fan profile good.
Trixx works fine with volts but has a problem with my fan profile.

When I apply the fan profile to my cards with Trixx no matter what I do it only applies to the first card so the second one gets much hotter, meaning so does the first and its very hard like this to keep temps down.

Afterburner fan profile applies to both cards

Benchmark run as mentioned above with 1070 and 1500:

Valley:

FPS=72.9
Score=3050
MinFPS=32.7
MaxFPS=149.9

Heaven v4:

FPS=64.7
Score=1629
MinFPS=24.3
MaxFPS=147.1

For comparison the same runs with the giga bios @ stock 1000 1375:

Valley:

FPS=75.0
Score=3136
MinFPS=27.1
MaxFPS=137.1

Heaven v4:

FPS=69.8
Score=1758
MinFPS=23.9
MaxFPS=157.1

I only have the saved benchmark pics - I'd have to redo if you want full details showing gpuz etc and reflash back the giga bios. Similar results to what I found I posted ages ago here:

http://forums.overclockers.co.uk/showthread.php?t=18487740

I'd like to know what about the 7970 bios could make it outperform at lower clocks.

If you want me to redo I will happily - but will take a little time to post the results (prob have to do at w/e)........

Probably your memories aren't able to handle 1500mhz so the ECC is fixing the errors at a performance cost, that is why you are getting higher performance with lower clocks.

Also after you change settings you should restard your computer, because sometimes the errors get "stuck" in your system.

I'm using trixx and have noticed the fan profile on my second card stays at 30%, no matter what profile I select.

Going to give afterburner a try again later.

 

[skyjawa]

So seems Trixx is a bit glitchy too, did you try complete driver uninstall and still does it?

Good point drangueos, I'll drop the memory down and re-run....

 

[mooey]

I reinstalled the driver but no difference. Having a fixed profile is fine but it doesn't seem to like a custom profile. I'm pretty sure afterburner profiles were fine.

Apart from this the bios has been spot on.

 

[skyjawa]

Ok, did another 2 runs one with mem at 1400 with the core still at 1070 and another with the giga speeds of 1000 and 1375.

1070/1400:

Valley:

FPS=71.3
Score=2985
MinFPS=31.9
MaxFPS=146.5

Heaven v4:

FPS=63.4
Score=1598
MinFPS=23.5
MaxFPS=143.4

1000/1375:

Valley:

FPS=70.2
Score=2939
MinFPS=30.9
MaxFPS=136.3

Heaven v4:

FPS=59.9
Score=1509
MinFPS=22.3
MaxFPS=133.8

Looks like the memory is fine at 1500, and from what I've noticed in the past with my cards 1500 is ok but anything much more I get crashes.

I'll reflash the giga bios on Friday/weekend and re-run for comparison. However - this bios seems bloody good for a tweaked 7950 eliminating all the boost issues especially since 99.9% of people can't run the giga or don't want the HDMI disabled.
