tonight i'll flash ASUS bios...well i'll report LATER...

[Oese]

btw interesting finding:

setting ramspeed to 1320 results in 1318,8mhz AND LOWER VGPU NEEDED!

I can use 1000mhz gpu @ 1,25v now if ram is set to 1318,8 instead of 1300. I resolves this "stripy" screen thing or at least loweres vgpu needed to avoid stripey screens...

[Nizzen]

Is there a way to disable gpu recovery in catalyst 9.10 rc9 ?

Flash was easy as pie. Thank you to the person that created this thread and the flashing guide at the beginning of the thread.

[Utnorris]

First overclock, I will play with it more tonight. Stock voltages.

[flopper]

as the echo of the voice, join the dark side runs deep into the core to unlock the power,
Unwinder from Rt and msi afterburner solved the issue,
5850, 1ghz, 1.2v 4ghz i7 4 cores HT off.

Nice but can you say to us how doing that ?

With which tool ? I thought i would have needed a unlocked bios to do that !

add string to afterburner.[worked for my card]
load afterburner set volt, and then amd gpu tool to set clocks.
No bios flash.
Tried 3dmark06, but crashed at 1.2v, set it at 1.225 and then it run trough,
got 24266p

I had displaying flashing when I tried to OC just the core with the AMD GPU tool.

Flashing works perfectly for me

Ok , thanks . It works very well but not in crossfire . In fact i can not use amdgputool to set clocks of the second gpu : instant freeze ( under vista 64 ) even if i increase by 1 mhz the second gpu !

I wait impatiently an asus or unlocked bios .

yea when there is a bios for 5850...
u got 5870 totally different story as far

I guys i'm going to leave my score here!

System:
Amd Phenom II 940 @ 3612
nb@2.8
mem ddr 2 @ 1066
XFX 5870 @ stock clocks

Ati driver: downloaded the ati recomended driver from amd website.

I would like to know your opinion because from what i see comparing to
others users with phenoms my score looks to be a bit higher @ gpu score

in ati catalyst in performance/quality i left it on balanced (hope you guys did the same, so we can compare even systems)

cpu score: 12481
gpu score: 15918

link: http://service.futuremark.com/result...&resultType=19

I left all settings in vantage that came by default!

I'm using fresh windows 7 rtm x64 install.

One question, @ gpuz 0.3.5 to all of you from what i've seen it appears
sub vendor ati, mine it already appears XFX Pine Group don't know why, i thought it would appear ati (since all for now are the same "reference")

Henry, are you having to put a lot of voltage through the GPU to hit those Mhz? That's pretty good to have a HD5850 that overclocks to what the HD5870 overclocks too, just wondering if you are putting insane amount of voltage through it and also what type of cooling.

[Henry]

Utnorris : vgpu 1.2v, stock cooling (fan 100%).

Seriously? It takes me 1.3v to hit those on the HD5870. Don't make me regret my choice.

Ok, so here are some benches at 1.3v and 4.6Ghz:

Not bad, but there is more there, way more.

At this stage can those that have had success sum up their preferred tools used for 5870/5850 and get jared to update the op maybe?
Im not sure whats getting the job done and whats not

I got a sapphire 5870 after reading here so thx for the posters experience

[F.stop]

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 know exactly what you mean, great card for the time but i didnt like the heat output at all. atm id say 5870 is about half as hot which is a v.good thing
