Try Sapphire's TriXX instead if Afterburner is keeping your cards upclocked.
The clocks reduce fine on the OCed 6850 in my Ph II 940 computer. Haven't tried it with a 6870 though.

Can anyone benchmark FFXIV high setting on your 6870? Preferably once at your highest aircooled overclock and once at 1000/1150. Use the first character.
I am deciding to either get a 6870 or the older 5850. Yes I know the 6870 is a way faster card and newer tech but i am being offered a 5850 at a really good price. If the 6870 is not too much faster I might a 5850 instead and save some money.
Thanks in advance.
why dont you guys set this in profile and saved settings?Quote:

You may find the below useful. At about 880 on the core a 5850 should be around stock 5870 performance in that bench.Quote:

Again, a 5850 with proper voltage should not have a problem matching or passing a stock HD 5870.
Thanks for the links! The stock clock scores for 6870 looks really good but It seems strange that the overclocked score is only 4760? My mate's rig with a 5850 clocked 1ghz was hitting 5130. So it seems you are right oc 5850 does exceed a stock 5870.Quote:

Any ideas?
Anyone noticed that once you get past 950 core on these 6870 chip minimum and max frame rates in most games see very little improvement. It seems very much like the 5870s. They almost seem tapped out. I returned mine after noticing this and went back to a gtx 480. The 6870 isn't a bad card , in fact it's very good but I think it's a bit over price it should be 200.00. The used gtx 480 and 5850's are the best bang for the money out. Just my two cents.
My FPS seem to scale decently, only have a 6850, but up to 1080Mhz on core, and min FPS keep increasing. Many other factors can keep min FPS down.

Is anyone using Afterburner 2.1 B5?
I've been using Trixx but wanted to take the voltage a little higher.
I used AgentGods voltage unlocker, which worked for the voltage.
But now the clocks are locked at CCC limits, and trying to edit AB's config file to unlock clocks
won't save the file anymore (Access Denied)....:(
Any tips on how to get higher clock settings with AB Beta5?

My first bench with 6950 ;)
Max overclock in CCC - 840/1325
http://paulyd.co.uk/oz/6950%20crysis.jpg
Edit: My result with 0% on power control was a fraction lower, so there might've been a tiny bit of throttling with an overclock.
Unigine 840/1325
http://paulyd.co.uk/oz/6950%20unigine.jpg
Beautiful benchmark in DX11 ;)
Can you not get higher limits with afterburner? From what I've seen you should be good for at least 900mhz until voltage control appears.
Yeah i'll give it a shot with afterburner. I have to say, i don't even hear the gpu fan :confused:, thing is so quiet. I'm used to my modded fan speeds on my 4890 which was loud compared.
edit: Just got 43 fps on crysis bench with 4xAA, about a 5 fps hit from 0xAA, not bad :)
I just tried using afterburner, i set 'enableunofficialoverclocking' to 1 to get over CCC limits, but when i set the clock, it doesn't drop back into powerplay. I think i'm going to wait for better software. Unless it's ok to stay at 3D clocks 24/7...?
I thought i'd give it a ago anyway. So far 900 on the core looks stable at stock volts, benched through crysis and vantage, but 925 crashed out out on crysis... this is with default fan speed, i will give it another go but increasing fan speed up a bit.
http://paulyd.co.uk/oz/6950%20oc%20vantage.jpg
Well i tried pushing my memory, and it surprised me quite a lot. Benching crysis with 8xAA, i've managed to go up to 1500 (6GHz effective) without performance being lowered. 1400 spat out 43.5fps, 1450 gave me 44.3fps and 1500 gave me 45fps.
http://paulyd.co.uk/oz/6950%20crysis%201500%20mem.jpg
Still yet to try more! (bare in mind 4xAA = 8xAA on this benchmark, and vice versa)

Nice results Oztopher - I'm curious to know if you could clock higher than 925 MHz if you reduce the powertune % a bit (into the negative area). Sure, your overall performance will go down, but it be interesting to see if you could reach 950 or so stable.
Oztopher - How come 4xAA is actually 8xAA? I never experienced that before. Is it special for AMD cards?
yeah thats the one down fall of msi afterburner u have to setup profiles if u want powerplay to work
Thanks. Not quite sure i see the point of that though, the only thing i'm limited by now, is vgpu. If i did try that, i would guess in the instances where it's able to utilize the full ~950mhz it would just crash.Quote:

I think this is the maximum for this card on air.. it needs moar volts, since it's cold as grandmother boob.
Yes, but it would be interesting to see how powertune would manage adjusting the OC'ed core speed dynamically while running the benchmark. If the card is rendering a scene at 950 Mhz and it goes over the reduced set PT value of -5% (~ 190 Watts), it'll drop the core speed until it runs <= 190W. During less loaded scenes, you'd be able to gain some performance back due to the higher initial OC.Quote:

Voltage control and extended powertune control would be ideal!
Rick Hunter, i see your point, i might try it soon but at the moment busy :D got RC3 driver to install hehe.
On another note, i'm very pleased with the performance of the stock cooler. With the default fan speed (about 31% during half an hour of crysis warhead), max temp i saw peaked at 73c. However, this is almost INAUDIBLE over my 1350rpm case fans. Above 40-45% fan speed is when i start to hear it slightly.
Just for a test, i set the fan speed to 45% and ran 3 loops of crysis with 4xAA.
http://paulyd.co.uk/oz/6950%20temps.jpg
I was estatic with those temps, i can't wait until i can start whacking the voltage up because i have hell of a lot of headroom to go :yepp:
Edit: oh and i tried pushing my memory even more, but 1525mhz didn't produce any more fps over 1500, then just to make sure i tried 1550 but it froze up with in the first 3 seconds of the crysis bench... seems these chips ARE really rated for 6ghz.

MSI Cyclone cooler on Gigabyte 6870.
I got 890-1500 out of my XFX 6950. I tested it with kombustor. GPU-z and afterburner showed now sign of throtteling. 900 was unstable and it crashed. 1525 lowered performance.
But somehow i dont get the voltage control to work. I'm using the 2.1 Beta 5 of afterburner. But i dont see a voltage slider. And i did enable voltage adjustments. Some benshes:

Not the best test but it was a quick and dirty run of a replay in Starcraft 2 on x2 speed so it would not take the whole 8 min but only 160 seconds. the other runs where done on a 3933 GHz 6 Core with 2691 MHz NB.

Impressive. Although you might want to try the 10.12a RC3 drivers. Even though they have a lower driver package number they apparently 'officially' support the 6900 series. RC2 (and above) brought improvements to 3dmark11 for me, maybe some other games etc. i haven't really tried.
Also, a link to a GPU-Z test build that supports 6900 series, works for me :)

My asus 6850 (2 months old) has a strange problem.
It runs on stock voltage 925/1125, but when I try to reach more and up the core voltage, I get small artifacts(green dots) during normal desktop usage (browsing).
Where not talking about big increases: from 1.150 to 1.154 (trixx/afterburner) is enough to get the artifacts.
I also changed the bios to a asus 6870. It gave problems through hdmi (black screen), but on dvi it worked.
Same problems though, since the voltage is standard on 1.72. Flashed it back and hdmi worked again
Any thoughts??

update:
Just ran msi afterburner with the " force constant voltage" option.
Now the card doesn't downclock anymore, just constant 3d clocks. No visual problems. Only drawback, not good for gpu and power consumption.
play with my HD6870 an Unigine Heaven Benchmark 11X yesterday and max on air was 1050/1245 load temperature went up to 78c with the fan at 100%
so I took a XSPC chipset block and sat on gpuen it helped a little 1110/1245 load temperature was then max 45c, and the water comes right after the CPU.

Although with furmark temps just continuously rise, because of the fixed fan speed. Temps after 10mins or so of furmark reach just over 75c, and no doubt will slowly continue to rise.

New MSI Afterburner 210 Beta 6 with support for voltage control for HD6950 and HD6970

So does that mean we can't even use it on an unlocked 6950 BIOS? :shrug: sucks :(Quote:
Note for those who use modded 6950 cards. Afterburner provides voltage control only on reference design 6950 cards with 100% original 6950 BIOS and 6970 cars with 100% original 6970 BIOS. Afterburner's voltage control WILL NOT function if 6970 BIOS is flashed on 6950, it is supposed to be that way and it won't change in future versions and any "bugreports" on it or demands to "fix" it will be ignored.
But wait, found this:
Quote:
Yes, it is possible to override the database to make Afterburner voltage control working with 6950 flashed with 6970 BIOS. 6970 voltage calbiration info should be added to 6950 configuration file in this case:
VDDC_VT1556_Defaults = 9A 5C 9B 80
I havent had a chance to try it. I dl'ed it last night and installed it. That would really suck. I am tired of flashing and more flashing. I guess it would be better to have a modded bios unlocked than voltage imo....Quote:

I don't mind using RBE to increase voltage anyway. I have 2 BIOSes, a normal one with 1.175v which yields 950 core, and another 'extreme' benching BIOS which has 1.35v and that allows about 1025 core.
Any higher than 1.35v is pointless for me, it doesn't give any considerable stability to higher clocks... due to temps i'm guessing.
