^yep, its real folks.:banana:
Question: What's a recommended number from 1175 mV? I know everyone's card handles things different but I'm looking for "in the ballpark" number to work around in.
And quick tidbit: does anyone have an issue with GPUTool not recognizing the clocks? It shows up as -1 =(
EDIT: I unlocked my 6950 to a 6970, btw
depends on what you want, if its a solid 950/1450 you want try for aroung 1.230-1.250 ballpark, then around .025mv for every 10 mhz after
Pity it's not possible to edit the fan profile with RBE (well, you can edit it but it doesn't do anything since it's apparently a driver thing now instead of a BIOS setup).
yeah its a shame but on the other hand setting my fan at 43% is barely audible but provides decent cooling for the vrm's. setting it higher doesnt do that much better and sounds like a jet engine lol. Im keeping that fan setting 24/7, Im testing my final clocks and best bios tonight, Im settleing with 990 core though so I must find the right voltage+0.25mv for good mesure and then go for max stable memory, Im testing crysis for memory since it seems to throw artifacts more noticeably with high mem oc's. Does anyone know of any better games I could use for stability testing? 3dmark 11 test 4 is brutal when you loop it, I might stick to that.
Other then Furmark, Kombuster or one of the 3DMark programs I find the AMD's whiteout demo is very good for showing artifacts.
You have to edit sushi.ini to set your screen resolution and turn off vsynch.
thanks man Ive found stability now and Im happy with 975/1475 @ 1.325mv, Im keeping it this way now, the cards is cool so all is well.
This sounds kinda cool, I'd like to give it a try on my Powercolor 6950 @ 6970 atm with standard 6970 clocks running thru AB with its own fan automatic mode (atm 40-45% in idle, but it doesn't bother me, cos under load with FurMark card's barely reaching 74 celsius)
Dave, if all goes right, could I ask you honestly to provide your 975/1475 BIOS with further instructions for them fan settings like you use?
I second this, your overclock looks real nice =)
How are you keeping the card so cool? Liquid cooling? I had to set my fan speed to 65% to keep temperatures below 90 C and I'm at 1200 mV.
Also, ever since I set the max voltage higher, Furmark hasn't been stressing my GPU much since the graphics clock is constantly around 500-700. It's downclocking for some odd reason, so I've been using OCCT to stress the GPU.
aoir cooling, Ive got an antec 900 all fans on mediun so I think that helps a lot.
Any one got a sapphire 6970 bios with voltage mod , i cant get my head around this rbe
i tried winflash with a modded asus bios but got a mismatch or summit like that.
i might have one on saturday if you havnt got one by then, sorry, ment to do it last night but not getting much sleep of late with a little nipper, i doubt i will get a chance tonight or tomorrow night
No probs saturday will be fine thanks
Been doing some tweaking and following Hilberts review on my GPU's and his overclocking results I decided to give it a go.
Here you go then,
The aftermarket cooler on these performs really well and I have loads of air flowing through my rig. Off to test some games
Umm, not good! Hard lock as CoD MW multiplayer started a new game! I noticed many people saying they didn't need a voltage nudge at these clocks. I wonder.
More hardlocks. Maybe the OC is to aggressive? Everything appears fine at 2D settings. It's the jump to 3D clocks that is definitely causing the problems.
Perhaps a voltage nudge?
for a 58x0 series card(s) why use RBE? you should use Afterburner, get something stable then for hassles sake flash with those core/mem values, but only when youre 100% sure after testing.
I cant remember 100% my 5850 clocks, i think core would do 900 without extra volts, not sure on mem tbh, i think i could only do 1000 without overvolting, cant be 100% sure though and overclocking mem on the 5850 doesnt provide much of a performance boost, in fact it negatively affects performance beyond a certain point as you end up skipping corrupt frames and having them regenerated etc.
Cheers, going to flash back. I recall that there was an issue using Afterburner with these cards. Setting unofficial overclocking caused problems.
Im poking around in this neat program and im a bit confused at the moment. Could somebody clarify this for me:
VID1: 1000 VID2 900 VID3 1100 VID4 1065
Thats what im seeing in the GPU register window. What does these different VIDs represent and do i change all of them or just the VID4? I read the FAQ and online guide but i guess im just to green in this area to really get it..
Dave....I had flashed my card to be a 6970 but have since flashed it back to 6950. I would like to use this program to up my stock clocks. What would be a good way to do so. I know I can run 900 on my core but i cannot figure out how to do it with the stock bios. any help would be appreciated.
you cant, you have to change vendor id to allow it to work with asus smartdoctor to enable high oc range.
