Downclocking 6970 Memory!

[Ferret]

Could someone please help me out? I just bought this card today, I also have a 5850; they run way too hot.
Right now I'm running at 950Mhz GPU Clock, 1375Mhz Memory Clock. and +5& Power Control Settings. 406Mhash/s @ 71 Celcius with fan @ 88% (Louder than a Jet plane)

So please what utility do I use to downclock the RAM to 331Mhz. As stated here from the Mining Hardware Wiki Chart:

6970    423          995       2.4    PCI-E 2.1 x16    phoenix 1.48/poclbm    ATI Tray Tools, Clocks=995/331.25, WORKSIZE=128 BFI_INT AGGRESSION=11 VECTORS ,68C @ 65% Fan, HAF932 Case

MSI Afterburner

Still won't bring the clock down enough. Also MSI afterburner doesn't have any power options for me so when I use it the Mhash rate goes way down to 311 instead of 406.

In afterburner, lower the memory speed all the way down, click apply.  Then close afterburner and restart. You should then be able to decrease the memory even further.

Did exactly as you said. Brought it down to the lowest. Applied, closed out. Restarted. No cigar though.
Same minimum clock as before.

He means restart after burner, not your pc. If thats what you did.

I did both. :3 Still not going down either way :[

Have you made the appropriate changes to the afterburner config?

Code:

[ATIADLHAL]
UnofficialOverclockingEULA   = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode   = 1
AccessibilityCheckingPeriod   = 0

Only other thing I can think of. Hopefully that gets you going.  And yeah, just restart MSI Afterburner, not your PC!

BEAUTIFUL. Thank you so much!!!

Very welcome!

Have fun and go make some BTC!

Haha yep. Ty. I actually got the 6970 today, regretting it though.
I overclocked my 5850 to 342 Mhashes and it's running at a cool 61c (Fan at 40%) while the 6970 is getting 406 Mhashes @74c with the fan at 70%.
Might try to return it and pickup 2 more 5850's, possibly setup a new rig.

6970 on 406 Mhps at 74C? Nice! Seriously, that's cool and quite for these stupid things. Can't get any 58xx where I live, and my only option is watercooling whic as a mechanical klutz I'm not sure I can do. If you you hate the noise, return 'em. I've got 6990's and I have to go with a 6970 for my next card.

BTW, what settings (OC, UC, miner and flags) are giving you 406 Mhps on your 6970? Also, downclocking mem below 440 drastically increases stales on my 6990, and below 550 increases them from 0.5% to 1.5%. Something to keep in mind when you UC mem.

I used the CCC(Amd OverDrive) to turn up the +20% power after I used the MSI Afterburner, cause it was only getting like 340 or something without it. Too bad MSI afterburner doesn't have that option :/
Using the newest GUIminer with phoenix miner flags are: WORKSIZE=128 BFI_INT AGGRESSION=11 VECTORS (Haven't really messed with the flags that much)
If I get tired of the fans I might get a watercooling unit.

Edit: also might be worth getting Phoenix rising instead of GUI miner; due to the fact that you can set it to cooldown after it hits a certain temperature as a precaution so you don't brick your cards.

Add FASTLOOP=false to your options as well.

Shot it up by 1 Mhash heh.

Every Mhash helps! 1Mhash/sec*60sec==60Mhash more per minute. Work that out to a month.  It adds up!!

[Ferret]

Also I might add that the 6970's are XBOXHUGE compared to my puny 5850.

True that.

Sombody knows how far i can overclock the 9760 savely? At the moment I'm at 960/1100 with 74°C and ~411mhash with 60%Fan (stable).
Did I only need to look at the temperature or are there any other variables to take care of?

I did this with my 6870 cards and set them to 300 in MSI afterburner but as soon as i start mining the graphs on the right (if you scroll down you will see the memory clock graph) it spikes to 1050 (stock clock).  as soon as i shut off the miners it drops to 300

anyone know how i can get the card to run at 300 while at full load?
