OC'in my HIS 6870....right now i have it set at 1.225v 1000/1150

how do i get it to downclock when im in 2d desktop mode? its stuck at the above settings

im using msi afterburner 2.1 beta 4

i have 10.10e hotfix installed

edit:

When ever I oc my cards it stays upclocked.

[tbone8ty]

ok yeah hopefully a msi afterburner beta 5 maybe will take care of this...or ill have to use RBE bios editor


edit: when enablingunofficialOC in the .cfg file ("1") this makes it run at constant OC

so i switched back to "0"....i just cant go past CCC limits, which is fine for now...while i work on the RBE editor

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?
I run 2D crossfire at 1.43v and 765mhz/1101mhz
and 3D 940/1150mhz 1.2v.
switches automatically due to profile set.

tested and now run 385/500mhz 2D.
seems to work fine.

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

If you're interested in other titles, try that.

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.

YW.

A well overclocked 5850 is still a darn good card. Personally, I wouldn't replace one like that with anything less than a 6950. Reportedly, the 6950 is going to be about 299-320usd and may match a stock GTX 580 with overclocking.

We should see in a few weeks.

[Martin.v.r]

you can report here

there will probably came a edit tool later to HD6XXX
So try bios, then there will be looking at what people write

but you can use MSIafterburner,an set the vgpu to 1.4v whit this bios

Tested outside last night, 3*C ambients. This was the max I could get stable using the Trixx program @ 1.299v -

6870 overclocking is very impressive! Can you benchmark FFXIV high at these clocks and post the score?

Hey guys I'm trying to O/C my Sapphire 6870 with the triXX tool. I can't seem to get past 950/1100 (stock volts) and also I'm getting weird jitter in my mouse when I mouse over in the notification area.

Win7 x64
i7 930@3.6Ghz
h50
TriXX ver. 0.4.21

Nothing too serious...

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.

Well that notice the case with the Fermi cards I have tried. Yet they are hotter and more power hungry.

Hello everyone.. here is my first vantage...everything finished without any artifacts or defects...



I think there is more room for decent overclock... This is gigabyte 6870
