UPDATE:
Get all the vcore you need on your 5000 series GPU, plus the ability to overvolt memory (actually the 2nd vt1165 which controls VDDCI/VTT on 5870/5970, may help memory clocks slightly - Thx Hipro5) with the newest beta version of RBE. Unload your bios via Gpu-Z, edit via RBE beta, flash back. First bios in the thread was a modified HD5850 @ .95 157/300 idle and 1.25v/1.15v 1000/1300 load. Very Impressive - expect a whole new host of desirable bioses popping up soon. If you have RBE experience, get to work!

The overclocks of our card are 835 MHz core (15% overclock) and 1260 MHz Memory (26% overclock). For your reference, the defaults are 725 / 1000 (GPU-Z is showing the wrong values due to a bug which will be fixed in the next version). As a percentage those overclocks are really nice. The maximum core clock of 835 MHz is clear evidence that this GPU ended on a HD 5850 because it could not handle the HD 5870 clock speeds of 850 MHz. The memory chips are exactly the same as on the HD 5870, which results in roughly the same maximum memory clock. In essence you can get a HD 5850 and overclock it to almost HD 5870 performance levels in just a few minutes. I would also like to point out that you can increase the voltage for better GPU overclocking. The default voltage of 1.09 V is quite low and there is plenty temperature headroom as well. So I ran a quick test at 1.30 V GPU and reached a maximum core clock of 1000 MHz.
As mentioned in the HD 5870 article, overclocking the memory on these cards is quite different from any other card so far. Normally you'd expect rendering errors or crashes, but not with these cards. Thanks to the new error correction algorithm in the memory controller, every memory error is just retransmitted until everything is fine. So once you exceed the "stable" clock frequency, memory errors will appear more often, get retransmitted, but the rendered output will still look perfectly fine. The only difference is that performance drops, the further you increase the clocks, the lower the performance gets. As a result a normal "artifact scanning" approach to memory overclocking on the HD 5800 Series will not work. You have to manually increase the clocks and observe the framerate until you find the point where performance drops.

There are 3 ways to get past AMD clock limit:
1) Get new BIOS from your vendor with extended overclocking limits if possible. AMD allows some vendors to have higher reachable clock limits that others.
2) Use AMD BIOS editors like RBE, some of them are able to override AMD limitations and edit overclocking limits.
3) Use AMDGPUTool, ATITool or RivaTuner. These tools can optionally use advanced undocumented AMD overclocking interface bypassing the limits. However, keep in mind that this interface is incompatible with PowerPlay (so your 5870 will start eating 100+W instead of 20W in idle).
DON'T TRY to use multiple tools accessing voltage controller AT THE SAME time. It CAN be dangerous, especially if some other tool is WRITING some data to VRM (and tools that monitor VRM temperatures WRITE data to VRM). Trying to display VRM status in ANY combination of AMDGPUClockTool, GPU-Z, Everest and Afterburner is DANGER. If you REALLY need to run those tools together, disable voltage controller monitoring in all of them but one.
Probably giving easy voltage controls to beginners was not a good idea. That is why it is hidden that deep in RivaTuner and available to power users only. Anyway, that's MSI's choice. There is always a balance between happy hardcore overclockers and unhappy beginners and vice versa.

HD5970 RISK LADEN WATERCOOLING SPECIAL:
Super disclaimer: Not responsible for destroyed cards.

Cards on full cover water might reach 1200mhz core / 1400mhz mem. If you can cool the dozen or so voltage regualtors that love to reach the boiling point (http://www.xtremesystems.org/forums/...8&postcount=35), then you can oc to the max. VRMS, not core temps are your limiting factor. You're going to need an ASUS voltage tweak 5970 bios (for use with smartdoctor), afterburner edited with unlocked CCC limits, ASUS smart doctor, and all the other basic software.
If you know how to control the I2C values, it's possible to set your memory voltage higher than 1.15v (1.15v is maximum Vmem available via the ATI overvolt tool). Rivatuner in combination with the knowledge from the voltage soft-mod threads linked at the bottom of this post may help you. First clock your memory to the highest stable speed and stress test for decreases in performance.
Flash to the asus 5970 bios and use smartdoctor to get your core/engine voltage to ~1.45v, however ASUS bios clocks in CCC are still capped at 1000mhz. AB currently maxes at 1.3v. AMD gpuclocktool should raise mhz higher than 1ghz limit - this will likely disable powerplay 2d clocks as would AB's unofficial overclocking method. So far the highest 5970 OC I've seen is 1030/1300.

nice thread jared, just one thing the link to gputool which is pictured is going to amd gpu clock tool which is a different animal and not as good as gputool which you have pictured but alas gputool is not publically available yet which works with the 5800 series cards but its coming, then we'll see some real overclocking especially with the 5850s i feel, thanks for starting the thread off and i'll be watching this thread eagerly

[chispy]

Cheers

Chispy.

[jaredpace]

Yes absolute respect for unwinder & wizzard. I'm just linking to currently available software. Glenboy thanks, I just realized that was a gpu-tool screen, it's fixed.

Hey NP good guy then its all good . Take care.

Still testing but like someone already said we really need a RBE update to support cypress and cypress XT gpus so that we can remove that god awfull amd gpu clock limit.

[mR Yellow]

Reserved untill software is released....

*side note, From looking at those stock to over-clocked results there doesnt seem to be that much of a improvement, i mean stressing the card right out for 4 half. fps ? lol*
are you cpu limited or bottlenecking those cards ? clearly something is wrong becuse when i had my 2x 4890s overclocked from stock to 980core the results where much much higher.

Yes, that might be true for Crysis but u might see greater gains in other games.

BTW U guys know about the new error mem checking in the 5xxx series? Higher OCs sometimes result in slower performance.

Can't wait to see how the 5850s OC.

[flopper]

I would assume we need the RBE tool to remove the ATI set max overclock mhz with a modified bios?

[SubZero.it]

Want my card here!!!!!!!!!

[Sh1tyMcGee]

Mine does 900/1300 easy. At this point, overclocking is pointless for me. All games run very good.

[Quad-Damage]

Any info on HD 5870 vs other cards?

[okorop]

is msi after burning working fine with all the 5870 or only with msi brand?

[ViRuS2k]

Everything works fine apart from upping the clocks past 900 and 1300 otherwize you have to use AMD GPU tool to bypass those like i have had to do untill RBE gets a update.

Just quick report before going to bed (long day tomorrow )!

Sapphire default GPU Vcore is 1.125V load
not good enough for 960MHz core in FureMark (freezes after 30+sec.)
upping vGPU to 1.185V is enough for stable 1GHz on core! Haven't had time to try higher clocks on this voltage yet. It will need to wait till tomorrow!

BTW 9500 oMarks is easy with this card


@okorop: Afterburner works fine on Sapphire HD5870 which should mean it will work on any reference HD5870

thank's I am waiting for three sapphire 5870, so everyting is working

[purecain]

i got back into the country today, rushed home... picked up my new sapphire 5870, went into my office at home eager to get my tech hit... only to find the electrics off till monday....

wtf....landlord+electrician=epic fail

end of rant....

[QUOTE]

No, it's 1.162V, at least thats what mine is at load.

[mR Yellow]

Any OC results yet for the 5850?

[Oese]

waiting for my card :p

[Chickenfeed]

I am curious if anyone has had any display driver has stopped responding issues yet. If I really put the hurt on the card with something like Furmark's stress test, eventually the driver will stop responding ( this is at 900/1300 ) Games however have been solid and then there is the fact that Furmark's stress loads things a good 8-12C hotter than even Crysis Warhead on Enthusiast with AA. I've yet to try overriding the fan to run at high speed in Furmark but I may try that out of curiosity ( I find the card becomes quite loud past %40 speed but no game seems to get it that high ; only Furmark - games tend to be from 25-35% with the fan profile)

[Migi06]

5850 should have volterra VT1156MF chip on the back:

[Chickenfeed]

Here is a Vanatage P run at 4GHz cpu and 900/1300 on the 5870. For whatever reason GPUZ doesn't seem to report the overclocks for me.

[Bojamijams]

Please forget about Furmark.. for any and all reasons... as you said yourself, even the hardest hitting game at its highest settings doesn't put anywhere near the kind of stress+heat on it..

[Chickenfeed]

I agree with you there but I am somewhat OCD in that if anything causes instability or driver crashes I /wrist In the realworld though the card is doing fine ( doubt even 2560x1600 with 8x SSAA would be as nasty as furmarks high stress test )

[nascasho]

Holy god I managed to pwn my other score using just one card this time!

But how the hell are others breaking the 19k mark with one card?!
