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

Ticonderoga said:
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.
 
Hi guys,

I tried flashing this bios today on my HIS 7950 Boost (to be specific I flashed the HIS7950.rom via Windows), and also overclocking it.

I managed to get the following settings benchmark stable:

nGghPtL.jpg

I couldn't get the core clock any higher with 1.225v and I didn't really want to increase the voltage higher.

Also the memory voltage is at stock 1.6v because if I increased it at all I got the "blue lines" crash, so 1675 MHz was as high as I could go.

BUT here is the issue: I tried Far Cry 3 and it crashed after 5 mins, so I put the vram back to 1500 to make sure that wasn't causing it. Tried again and it lasted longer, like 15 mins before crashing again.

I tried bumping up the vcore voltage up to 1.231v and still get crashes @ 1.1GHz, so I reverted the clocks to stock and the game crashes even faster, before the game has loaded, twice in a row.

I'm wondering whether it's the BIOS. When I flashed it I got this message (I kept this screenshot because I knew it looked odd):

Can anyone help please? I have no clue what to do. I did make a backup of the BIOS before I flashed it.

Edit: Also my ASIC is 53.4% if that helps, don't even know if that is good or not though.

Flashed my secondary card and running stable at 1070/1500 1.18v. My asic is crap but keeps up to my first card (7970) at 1025/1500 now. Ran bunch of benchmark 3dmark11 (18,000) fire strike (16,000), vantage (55,000) and played couple rounds of bf4 with no issues. Have to run power at+50% though or get throttling bad. Seams like the 50% doesn't add to the tdp but only makes it more sensitive. Meaning 50% is 20% on stock bios and 25% is 10% on stock bios. Kind of pointless.

Thats far to high a voltage for that clock.
my 2x 7950s his cards run perfect @ 1138v @1125/1425 thats 1.13v
 
Every card is diff some are crap. My 7970 needs wpmt even do 1200mhz at 1.3v at 65°C but other people get it at 1.2v, doesn't help it is a piece of junk and vdroop goes down to 1.19v when set to 1.3v and bouncing all over between 1.19 and 1.25v. Dual X 7970 with blue PCB sux. 7950 dual x with blue PCB is reference PCB with AMD near pcie so its good.
 
Anybody know if this bios is compatible with sapphire dual x non boost ? I assume not considering my non boost card bios wouldn't work on my boost card. So I'm guessing this bios is only for boost cards. Be nice to have both cards running at 1070/1500 without having to screw around with afterburner.

rip out both bios`s and write boost and noneboost on them and i will modify
Send me your bios`s i will custom modify them for you for 1070/1500 with boost disabled and 50% powertune and optimized fan profile for both cards. ;)
 
I don't see the point of the 50% power. Its not more than the 20% its just more spread out. I know this because with the +25% I get throttling with the 1070/1500 bios and with stock bios at the same clocks and voltage I get no throttling with +20%.
 
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. ;)

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.
