    awesome, now are there any GTX480 kickass BIOS's? My card clocks really well at 1.075 to 850/4400 but then anything higher results in eventual screen freeze (funny, cuz there are no artifacts, just random freezes after t-x minutes.

    Just in case people are interested, I removed the top shell of my 470 GTX (not the cooler itself, just the top plastic cover) and spanned 2 120mm fans across the entire gfx card and disabled the default fan. Fans are running at ~2000 RPM.

    After half an hour of Stalker CoP @850 core, 1087mv, my highest temp recorded was 75° C instead of 90° C :p

    For those that don't give a damn about looks this is one hell of a cheap way to cool these cards down. I'm going to install Metro if I get some more time.

    What sort of clocks can I hope for on stock voltage on a gtx 480, I only want a moderate clock and don't want to screw around with BIOS updates, would 800 core be too much to hope for?

    800 should be pretty easy

    Sweet, ordering my 480 tomorrow, if it can get 800 core with the vanilla card I won't bother ordering the amp edition.

    That's cause you need flash using nvflash with all the flags set -4 -5 -6 xtreme tuner HD won't work cause its like dumping 480 bios on 470 card safety feature, but nvflash is only way doing it.

    Voltage @ 1050 and fan speed set to 65% from 42%

    Can hardly hear any noise, more quiet than my old GTX 280!

    You can only run nvflash from DOS. It's quite complicated process to get DOS prompt though, like you need either usb flash or blank cd then go about putting windows me or windows 98 on it, theirs program done by HP which can turn a usb pen drive into bootable device which allows dos commands. I suggest you go about google HP usb pen drive bootable process, far too long process for me do step by step guide. Once you've done it using nvflash is a breeze or manually flashing anything from dos like motherboards an such.

    What settings should I have furmark set to, I want to get my benching done in the first hour or so so I can get to gaming... getting my 480 on monday, i'm going to to a few benches @ stock and then go straight to 850/1700/1000 @ 70% fanspeed as kanej2007 has done, I don't want to push memory any higher as the vram gets insanely hot as it is. DO you think my case will be problematic?, I am using antec 300, 5 case fans... side intake front intake, rear and top exhaust...it's fine with my 280 on auto..and it never goes over 40% even when gaming with 16qaa and such...

    How long should I run furmark for before I can assume it is stable, 30 mins?

    How is your GTX 480 going? You happy with it?

    I've only had mine 2 days and I'm quite satisfied with it...

    With yesterday's settings, it was slightly unstable, almost but pushed a bit too far.

    I applied these new settings, and performance is a lot better, max temps are a lot better and not much noise...

    I increased GPU Clock to 800, it was 850 but was not 100% stable.

    Put your Gpu Clock to 800, Shader Clock 1600, Memory Clock to 2000 & fan speed to 65 or 70%, your call...

    Those were the settings I have used to far, they are 100% stable, tried MSI Kombuster, was fine and did not get much higher than around 82 degrees, played some random games last night and this morning, so artifacts/crashing or freezing and the HIGHEST temp I got was around 82...

    My bandwidth also jumped up from 177 to 192.0!

    I haven't got it yet :( I checked with the courier, it clocked in my town at 4:10 yesterday morning ( it's just after midnight so it's only just yesterday ) so it should arrive today or monday...I don't know if they deliver on weekends.

    That sucks the clocks weren't 100% stable. But it's good to know so I don't go overboard...still @ 1050 voltage?, did you try upping the voltage to 1087 ( or whatever the max allows ?

    You just need bump up the voltage, my card 607MHz core default at 987mv for 880MHz core i needed 1125mv. I would guess 850 on your card probably needs 1087mv or 1100mv to be 100% stable. Can't remember max stock voltage for 480 on stock bios think its 1121mv or there about's, i use a unlocked bios which allows all way to 1213mv but isn't the core what's problem at those voltages but the cards vrm struggles.

    Yeah, I will increase the volts slightly to around 1080...

    I hate it when you need to wait at home all day, counting down the minutes waiting for your new GTX 480!!

    I get that all the time and hate it, waiting all day not knowing when your gadget is to arrive...

    Mine came yesterday afternoon at around 12:00. The second it came the next second it was fitted!! :)

    Yeah, I will do a hulk and rip the top of the box open...those 2 seconds to undo the cardboard latch will be precious O.C-ing time wasted. Post back with the 1.087 bench, try those same clocks because they seem moderate enough and certainly possible judging from other people's clocks. Don't worry about the 1.087 voltage because depending on your cards BIOS ( and maker ) the default clocks are easily that high on some vanilla 480 models, so it's not a risk. Going 1.15 etc though would be pushing it.
