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

[IC3]

1. Original Boost BIOS voltage was constant 1.25v no matter what you did...
2. Use latest Trixx to change the actual voltage and you shouldn't see any voltage jumps, it is also recomended that you reinstall your drivers fully.
3. I would also recomend installing only 1 overclocking software as in my experiance when I had installed MSI AB + HIS Iturbo or MSI AB + Trixx or HIS Iturbo + Trixx it didn't work proprley...
4. Set the fan to be more aggresive as the clocks are much higher then before, from what you are saying is that your card is lower ASIC and lower ASIC GPU's like higher volts.

I had some strange problems with GPU-Z that's why I use HAiNFO64 which tells me the lowest, avrage and highest temps, volts etc. Remember that FC3 is very badly optimized and I get similiar temps 66-69c 1070/1500 1.115v ASIC 79.8% - using lower voltage BIOS. Check with GPU-Z your ASIC, what about other games such as BF3 or Hitman etc?

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`?

 

[IC3]

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..

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...

 

[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.

 

[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:

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)

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

Spoiler

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

Did you tick the option Multi GPU or similiar?

Just resurecting this thread, I have my 7950 under water now, with a Aqua Computer AquagrATIx.

While I am testing I have it is currently clocked to 1170 (core) @ 1.25v (remember my asic seems to be the lowest I have seen on this forum @ 53.6%)reaching a max of 39ºC in Valley. There is more in the core at this voltage it is just where I had got too.

Any ideas on how high I could go with the core voltage? 1.3, 1.35?

Under water you could try these voltages and also your card is lower ASIC (the card likes/needs higher voltages for better OC).

 

[IC3]

Is it also worthwhile bumping the power % up to say 30 due to the higher voltages? I currently have it @ 20%.

Yep, when going over 1.25v

Hey guys, I've got an HIS IceQ x2 boost and tried flashing with the HIS BIOS as my card runs at 1.25v constant but it disables my HDMI port, any ideas or what I can do to get around this?

Edit: guessing this isn't right:

there must be something different with the x2 as I get no temperature or clock readouts in GPUZ using the HIS bios, flashed back to standard for now.

Flash back your original BIOS and PM kahboom. He will make a BIOS for your card.

Hello

I've tried the Sapphire 7950 BIOS, and it seems all ok, unless that the temperature metter is showing 0º. Is anyone having this issue?

Thanks!

Which 7950 do you have?

 

[IC3]

Kaboom seems to be afk from his thread at the moment. He probably got fed up of making bios for everyone.

He might be off on holiday

 

[IC3]

So I am now the proud owner of a VTX3d HD7950 boost edition with a ASIC of 62.1 %.
I know the memory on my Card is not that good for oc. What bios would you recommend me?

Another question... do I simply download the new bios, flash it, reboot and then everything is up and running? No need to do anything in CCC etc. afterwards?

You would have to ask kahboom, to modify your BIOS in his thread or do it yourself.
Yep, just download it (make a backup of your original BIOS!!!) then just flash it and you are good to go!
But don't try any of these BIOS posted as they are only updates to the BIOSes of specific brands (HIS, MSI etc) listed under in description.

 

[IC3]

just a quick question can uefi gop for windows 8 fastboot be added to this bios?

Very late answer, but it might help others looking at this thread, so yes it can as Kahboom and another member from overclock.net have worked on it.

 

[IC3]

Forgive the thread resurrection.
I've read and reread this thread until confident enough to give it a try and tonight I did.
I tried all the HIS bios's and all worked however I lost the temp readout in ccc, gpuz and msi ab.
I tried reinstalling drivers and programs etc after each bios flash to no avail.
Reflashed original bios and temp readings reappear in all utilities.
I don't feel happy running the cards with no way of monitoring the temps.

I realise that this is probably an old subject now that has run its course but hopefully someone can help ?

Thanks

Follow these steps and it will work

1. Unistall drivers (and any monitoring utilities) in Control Panel
2. Restart
3. Display Driver Uninstaller (DDU) use this for the drivers
4. Restart
5. Install drivers and any monitoring utilities
6. Restart and enjoy

I recommend following these steps everytime you flash the BIOS

Edit

What card (specific model e.g. His IceQ) do you have?

Edit2

You can send me the copy of Non-Boost Bios made by GPU-Z and I can change the clocks and volts for you.

 

[IC3]

Thanks for the help.
I will try that sequence, I presume I would flash the bios between 4 & 5 ?
I had pretty much done it using DDU, maybe not that exact sequence.
The cards are HIS Ice Q Boost.
Thanks for the offer of editing the bios for me that much appreciated.
Is that the copy GPU-Z makes and calls Tahiti by default as I thought that was the stock bios that does boost ? Or have I got the wrong end of the stick ?

Thanks again.

For the Copy of bios, follow these steps

1. Flash the NON-BOOST BIOS (Follow steps in previous post)
2. Once you've successfully flashed the Modded BIOS with no boost, make a copy using GPU-Z.
3. Put the BIOS in Winrar or 7zip (It just protects the file)
4 Send it to me and tell me what clocks, volts and what custom fan profile you would like.

REMEMBER to follow step by step

 

[IC3]

Ok, I have followed that sequence to the letter and still no temperature readings in ccc or gpu-z

This is strange, are you sure that your card has BOOST? I remember having same problem as you, when trying to flash a BIOS from non-boost version of IceQ 7950.

If you're sure that none of these work for you, just send me the backup of your original BIOS. I'll do a custom BIOS for you, also remember to tell me what clocks, volts and fan profile you would like. If you aren't sure about the overclock and need some time for testing, that's fine as I'll be home doing boring work...

 

[IC3]

Yep it sure is a bit weird.
Just tried the other bios's following the step by step method and still no temp readings although ccc and gpuz do see the overclocks.
So I thought right just flash back the original bios and without even reinstalling drivers or gpuz the temp readings are back.
Thanks for the offer of custom bios. How would I send my originals to you ?
Is it that trust thing ? Never used that.

Edit - yes they are boost, 850 stock boosts to 925.

Just to make sure, did you flash through Windows or by using an USB stick? To setup your trust, you'll need to click on it and there will be fields for you to fill out. You don't have to write down your name & surname, an email address is absolutely fine.

In the message attach the BIOS and write down exactly what clocks and voltages you would like.

 

[IC3]

Hi, yes I flashed from windows, there didn't seem to be any problems, didn't get any error messages.
I must be on a major senior moment this evening as I cant see any way of attaching files to the trust message

That's because you can't, do you use dropbox? If not, than use THIS
