How to I get higher voltage options than 1.138v in Afterburner does anybody know?

This modded ASUS BIOS will open up the extra volts and also drop idle volts and temps.

Max volts = 1.225v
Idle volts = 0.7v (down from 0.955v)

My 480 will run on 0.6v at idle but I set this BIOS to 0.7v so that all cards will run happily.
 
so far so good - bit of a pig to install. Seems like a pretty good performance increase (definitely in Heaven benchmark and Crysis but not much in DoW2 or Just Cause 2 surprisingly). In terms of noise - not really noticed it to be worse than what I had with my 4870.
 
aaargh back on offer ! and I'd just about pursuaded myself NOT to get one

can you "delay" orders at all ? just would like to order one but not get it delivered to work till ater in the week as out of the office for a day or so
 
So what are acceptable 24/7 idle temps? My machine is always on. It seems to idle at between 70c and 75c depending on room temperature. Heck of a lot of heat coming out the back at idle. This is with the fan at 30% which is just about acceptable.
 
I really dont get this dual monitor thing. I've never known of issues with running 2 monitors before, heck as I said earlier even my old Laptopc can do it, why is it significantly increasing idle temps on these cards?

Ive had dual screens with a 480 and a 5870 and both cards were a lot hotter when running two screens at idle.

It makes sense really when the card is working twice as hard having to process two displays,what case and cooling do you have?

Working twice as hard? Yea, because running windows is really taxing. Heck a GeForce2 GTS can do that.

I have a Coolermaster ATCS201 with 4 fans.
 
so the 40% idles were with dual monitor right ?

just if I set my 4890 (different fan I admit) the noise is very annoying, but 35% and less if un-noticeable

you can get sub 44% idle fan speeds without modding bios ?

thanks very much

I also read somewhere that running 120hz refresh rate instead of 60hz ups the idle temps..


(PS: I don't own a 120hz monitor myself to comfirm if this is true/false )

Read this

U CANT set a lower Voltage then 0.825 Volts...

Thats why Fermi Bios Editor doesnt show a lower Value..The lowest u can set the Voltage is 0.825, even when Nibitor lets u set lower value..U can test this with an Multimeter,
When u set lets say 0.725 volts in nibitor and flash it it still will be 0.825..

Just wanted to point that out...

thanks - manaaged to ally my fears of idle noise by checking my 4890 fan speeds rather than % ... and at 35% its at 2400rpm .... so I don't think the % can easily be compared to the 480 ( I was worried as 44% fan speed sounds very noisey on my 4890) ... 44% on my 4890 is 3,000rpm !

80% is almost 5000 !!!
 
I'm not entirely sure if i've missed this, but how are Asus going to know that you've changed your cooler on the 480 if anything does go **** up?

It's been the same for as long as i can remember, if anything does go wrong you can just shove the original cooler back on and they'll really be none the wiser. Have they started using warranty stickers or something?
