Can you modify the fanspeed bios settings for a...........

Phil2008 · 21 Jun 2011 at 12:31

HIS 6950 card, as the auto fan speed hardly changes while gaming, and temps reaches above 90c?

Should be able to create different fan speed profiles using MSI Afterburner no need to modify the bios at a guess.

sapphire trixx and msi afterburner will do it or you could edit the bios with rbe but the first two options are less fuss

Phil2008 · 21 Jun 2011 at 12:54

Ah thanks,, I'll try the after burner now. I would use the manual fan speed setting in CC, but then its fixed speed.

also interested in this for the asus card.... will msi AB have to be running from startup (like riva tuner) for the fan profile to be in effect? or will it be a case of running the program once and it wil remember it every boot? (i.e. without msi AB running?)

You could also try RBE but I'd say MSI Afterburner is much safer

Phil2008 · 21 Jun 2011 at 15:03

That seems to be working a treat, and Ive knocked off about 10c off the load temp. I had to alter the fan speed on my 3870 too as the idle fanspeed was going at 65%.. Why cant ati ever get a decent fan speed profile.

Running furmark with the rubbish ati fan profile was about 93c, but now it is 83c

Can't remember off the top of my head as at work, but believe there is an option for run at startup option.

is that hardware or software written?

will MSI AB have to boot up with windows for the fan profile to be implemented every start up? or will i just need to run AB once and it will tell the card to use that profile all the time... without loading MSI AB every boot?

I alway found it much better to mod the bios....

Then there no need to always be having to run software appz in windows..

with the bios method will it be and auto profile with a gradient? like i urrently have in rivatuner? so that as say the temp goes up by 1 degree the fan % goes up by 2? or is it just boundaries? like up to 50oc 50% up to 60oC 60% and so on...

Yeah I modded the bios on my 3870, or someone did it for me. How would I go about modding the bios on my 6950?

You can edit 3 points with RBE. The lowest duty value, the point where it begins to climb and the point where it reaches 100%.

So you could set a higher or lower idle duty cycle for the fan.

You could set the fan to increase much earlier and ramp faster.

With a dual BIOS switch this is a totally safe fix too, if it fails for whatever reason you just re-instate the original BIOS and start again.

sorry to thread hijack but i was wondering this myself as my XFX6950 gets to 85 degrees but the fan is doing hardly anything.. is there a way to mod this?

See above for the discussion.

Ive used the table option, now how do I update it? Ive saved the new bios and downloaded Winflash.

Phil2008 · 21 Jun 2011 at 19:47

Ive flashed the bios using this guide http://forums.overclockers.co.uk/showthread.php?t=18221844

But the fanspeeds hasn't change, but the fanspeeds has now changed it the bios, so why isnt it working,,, any ideas guys?

Maybe drivers are overriding the BIOS settings?

Ummm, maybe, but I thought the auto fan control was bios driven

metalmackey · 21 Jun 2011 at 21:19

I'm not saying they do but, AMD could adjust the auto fan speeds in the drivers. Say if they decided the BIOS settings of a certain card wasn't "quite right".
