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

mooey said:
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.

Same, fixed or auto with Trixx was fine, it was only when custom I had problems only applying to the first card. Guess its more an issue for XFire users than single card users.

Haven't tried the HIS util - but I don't really like it, had issues with it in the past.
 
Doing some reading recently and I'm guessing that the *updated* bios is the only way to change the Boost* voltage on these cards? Reason being that I never touched the voltage on my His IceQ and over-clocked it on what I though was stock* and for the last year have run my gpu on the settings in my sig for almost a year, it's only since I bought a 2nd IceQ recently and been benching that I realised the voltage bumps itself to the 1.25 max - which I'm not 100% sure I'm comfortable with - obviously I've been running my 1st card with this effect for quite a while and never seemed to notice it, so it's probably just me being a bit worried - would running the card with the original boost voltage really have such an adverse effect on the gpu (vastly reduced lifespan) or is it more of a case whereby it *may* reduce the lifespan but all-in-all its okay to run the card like this?
 
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). ;)

I have a MSI 7950 Boost edition with 2 six pin power connectors and memory at 1.550. Which Bios can i try?
Click to expand...

I'm using the 1070 core, 1500 memory BIOS in the "MSI Boost TFIII Oc 7950.zip" file.

I've overclocked it further to 1125/1575 on stock volts and now running at 1.18v rather than 1.25v with the boost BIOS.

Yep, when going over 1.25v

Ok cheers, will give it a try, seem to be hitting the a limit of 1200 on the core @ 1300mv (temps are good @43c in valley), 1250mv actual under load, hopefully bumping the power limit will reduce this vdroop.

If not I guess I will post in the original thread and see if the volt limit could be upped to 1350mv.
 
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 :D

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?
 
I've got a funny feeling the Iceq x2 is not a fully fledged boost bios even though it's sold as a boost card (925 1200 default clocks) - I've set the VDDC in Trixx and watched it in Trixx and GPU-Z whilst gaming and it seems to stay at what I set it to or below.

Is there anyway of checking if I've got boost enabled?

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?
