*** Official Radeon HD5800 Series Overclocking Thread ***

Revision history
v1.22
•Added clock tuning wizard.
•Changed fan controller bug workaround settings' description to point out what it does a little better.
•Improved program's startup routine.
•Fixed "GetClockPos reported 0"-error that came up on loading several 4xx0-BIOSes.
•Added preliminary support for Radeon 5870. Note that I'm still not sure about 5850's DeviceID and that signature saving and loading will most likely not work properly on 5xx0s with this version. Furthermore, VT1165 programming is not functioning yet.

Hi Destroyer, what score do u get with one card?

I did some more testing last night with the card and i'me seriously thinking that my Vantage score is low due to CPU bottleneck. I thought PII 940 @ 3.6 would be enough.

I've tried everything...that i could think if at least.

My GPU performance score is 12100 in vantage.

3Dmark vantage performance: ~14000
3Dmark 2006: 19200

cpu: 3800
nb: 2800
mem: 1600 8-8-8-22 1T
vga @ 900/1300 (max values in catalyst)
windows 7 x64 rtm
no tweaks, just normal settings


and yes, this cpu is limit the graphics, specialy in cpu score

other score:

http://service.futuremark.com/compare?3dm06=12162278

cpu: 3400
nb: 2400
mem: 1333 7-7-7-20 1T
vga defaut

Thanks for the Asus bios flash tip, did that to my GB card and now I can OC past 900. It needs 1,275V for 1Ghz though so it's not a good one eh?

Anyway, I am getting crappy scores in Vantage as well. P18200 with the card at stock clocks, P20000 with the card at 1000/1300. CPU score is 36500 (Gulftown @ 4Ghz) so that kinda sucks

I compared my scores to Bills and I roughly got 20 FPS less than him in the two GPU tests, so something is off there. May be due to the OS? I'm on Vista 64, he's running Win 7 64

Oh well, I guess we need a new driver... like Bill already said we experienced severe FPS drops in Vantage with 2x 5870, we got a pretty crappy score there too.

Edit: 3D06 shows good performance, 26k at stock GPU. Would need more CPU mhz for the GPU tests ofc

Well i tried:

-1504 bios for RIIE + i7 920
-Install Vista Ultimate 32-bit and Windows 7
-flash cards with asus bios
-changed CF bridge
-changed psu
-tried all availble drivers
-tried a few ram modules (corsair, cruical, take MS)


And its still the same crap... artefacts and decreased performance when running Crossfire...

ing unbelivable, after spending 700€ on this POS....

ok this might not help, but I have had similar problems with crossfire on Vista 32 bit. Have you tried any 64bit operating system? 32bit would give me odd screen flickering / corruption while running 3d apps with crossfire enabled. Nothing like that on 64bit Windows 7. I didnt try to debug the issue on 32bit as I had it on my old hdd which i use for suicide bench runs :p

[H3llSp4wN]

does anyone tried to flash a 5850 with the 5870 bios?

would it help to unlock the other 160 shaders left?

sorry for my english tkx

ummm i dont think it will work man...you will get a expensive brick

but it is up to you

[Rattle]

so far i am good at 950/1300 just using asus bios and 65% fan speed. pretty damn happy, i'll keep pushing see where she tops out at stock volts.

thanks Funky

[barong]

sorry noob question, how do i raise gpu voltage on my 5850?
should i flash my bios to run over 775 / 1125?
please noob need guide here

Well one of the cards finally give up and died... So i guess that was the problem im getting an replacement.

wait.
need patience.
no programs out yet nor bios for overclocking.

[Theta]

For the 5850, you need to use AMD GPU Clock Tool, and MSI Afterburner. There's nothing else out for it at the moment.

[x0m3g4x]

I can't wait for the ASUS bios for the 5850, hopefully my 5850 will get here monday, I am interested in some benches, after seeing how the phII is showing some odd numbers in vantage.

[Theta]

There's something else floating around out there that we don't have access to (GPUTool, perhaps). Frankly, the MSI Afterburner doesn't work reliably for the 5850 (regardless of BIOS) with regard to voltage increase. It gets reset by AMD GPU Tool, and even at random during the clock switch to 3D.

I guess we'll have to keep waiting - the only way some reviewers were able to hit 1000+ on the core with 1.3v was with tools that are not publicly available. That's my gut feeling, for now.

My HD5870 is doing 1Ghz @ 1.162v, flashed to Asus bios and using MSI After Burner. But it's also water cooled.

[GLENBOY]

spot on theta, i have the 5850 and mine i had the voltage upped once that showed in the monitor window but that was it, all bioses which are publically available the 5 posted on techpowerup are all the same bios regardless of brand , and i tried one just to be sure so as you say we either need a newer bios like asus etc or gputool not the amd one but the techpowerup one, come on someone help us guys out

thats extremely nice

that clocking up/down with msi tool is right, but it doesnt occur if u exit msi afterburner. i only use that tool together with unlocked ccc its very handy and reliable. AMD GPU clock tool is the thing that bugs around...

Guys, i experience some scary thing today. Running at 1gig/1300 @ 1,3v as all the time, gpu @ 46°C at full load and vrm @ 80°C, suddenly i noticed my radiators fans spinning up.

i had everest running in the back first time.. i just spotted vrm's 126°C and i manually shut down all 3d windows and restartet.. wonder what was happening. didnt look at gpu-z though or anything else, gpu-temp seemed normal if i remember right, but water temp was higher then normal and fans blowing, although vrm temp doesnt affect the water since they are passively cooled...

i suspect everest... although it was running for an hour before in the back and all was ok.. will see.....

[F.stop]

whats the heat output like with these cards, real world, 5870 vs 5850 any difference? whats it like comparing them to the 4870x2 space heater

[Oese]

space heating capabilities have vanished somewhat xD more like dual card rendering, single card heating xD

[F.stop]

woot to that

[Utnorris]

So I just want to make sure, but I can use RBE to flash my XFX card with the Asus BIOS, correct?

[dnottis]

RBE is to edit your bios. Just grab the Asus bios and flash it. I backed up my MSI bios with GPU-Z.

[Utnorris]

Will winflash work?

http://forums.overclockers.co.uk/sho...php?p=15022061

I used those files and followed those instructions.

[Utnorris]

Yeah I saw that, just use to winflash. Oh well, guess I will try it that way. Thanks for the quick response Dnottis.

Given I came from using a 4870x2 for over a year, I can say its a improvement (it uses a tad more at load then the X2 did at idle ) My room doesn't get really hot anymore which is nice for a change. However it just started snowing here so...


I haven't done much more testing with the gpu clocks but I've found the card hard locks the machine when playing GTA4 regardless of voltage yet I was able to play Crysis no issues for a few hours straight (GTA 4 it would hard lock in 1-5 min ) Funny enough I've been playing a lot of Daiblo2 which is just ironic given its one of the oldest games I own and runs on a wrist watch I honestly haven't found the gains overclocking noticeable enough to warrant the extra noise and heat to be honest but I will reserve judgment until drivers mature.
