I'm with you, let them burn them up...  not only is the electricity the issue.  this rig as been running without stopping since My9th.  I think I upgraded cgminer that day.. 

I cant remember exactly how many watts at the wall, i have that in another post..  i think 850-900

Tried an over clock to 913MHz core clock and 1100mV, VRM's at 100C and GPU's at 75 with fan@~90% (loud...).

Been stable for half an hour so far, and still running, we'll see...

All of this overclocking on 5970 is a great way to kill your card.

BUT keep going, less difficulty for moi !

Don't mind AMD and them stupidly making undervolt because you know better, right ?

Look at above poster showing how his cards died, hope yours do the same !

What's the best brand for 5970 in terms of overclocking/Mhps?

I got my Gigabyte 5870 to 450Mbps without much sweat, which is quite high for a 5870.

But my Gigabyte 5970s can't seem to go post 700Mhps without freezing the whole system  :/

I'm running them at 180/800MHz/Default voltage

All of mine are XFX Black edition. all will do 900mhz both cores on 1.05v and get ~800mhash. I can run the second "cooler" cores up to 950 on 1.05 but it's simpler this way.

all of my 5970 (8+) after a continuing year of operation at stock 725/300 and nearly 90c are off!
some of them with fun problems (easily fixed) others with BSOD (never fixed!)
all my one core cards 5850/5870 (10+) have no problem at all up to now!
i wonder if dual cards are not designed for continues full operation at high temp conditions!

I doubt your single core GPUs were run at 90c, were they? I'm betting if you had undervolted them a bit, and had better airflow, they'd still be running.

Mbps? You mean MH/s? Wink I kid...

It's really card dependent. I like PowerColor, Sapphire, and Asus. A lot of people have good luck with Gigabyte. I've heard to stay away from XFX and Diamond, but again, YMMV. There is no BEST brand for OCing.


Also, while a 5970 is technically 2x 5870s in one card, the voltages are lower to keep the power/temps down. Stock voltage on a 5870 is 1.174, while stock voltage on a 5970 is 1.050. If you lowered your 5870 down to 1.05, you won't be getting 450MH/s.

If you raised your 5970 to 1.174, you MIGHT be able to get 400+ per core, but it would be a very bad idea. Power draw increases, temps become too much for the shared cooler, and your VRM temps would be through the roof. Not a good idea.


Side note: Here are my 5870 speeds, for undervolting comparison:
460MH/s - 980/300/1.174 - My "all out" setting
425MH/s - 925/300/1.000 - My "max profit" setting
350MH/s - 755/300/0.950 - My "keep the temps down" setting.

I think my card can get higher clocks at each voltages than average, so yours may be a little lower.

The 5870 has more power phases and better VRM cooling than the 5970. Even if the GPUs on the 5970s are cherrypicked on the 5970s, you'll have trouble hitting the same overclocks as a 5870.

It seems that at least ref 5970/5870 and some custom boards as well (sapphire 5850 xtreme, first rev) can change the vcore in much smaller increments than I first thought. If you dump your bios from the card and open it in RBE and you see that "GPU Registers" is available you can use that to set the vcore down to 0,1-0,15 increments at least(didn't bother to check smaller changes, important is to not touch the vcore settings for the profiles but only change it in GPU registers if you want to flash the cards). And yes I have confirmed that the changes do actually take place and affect power usage. If the card (most ref boards) is recognized in MSI AB it seems to be able to change it in these small increments as well while other software seems to be working on another level (no fucking idea how it works, error and trial is my way!)

Cards that do not have "GPU registers" available are the cards that get's stuck in the "steps" no matter what, they vary from different boards from different manufacturers and only testing can really determine what vcore they actually run at. ALSO on these boards and the REF boards you can set vcore with some software (Asus gpu tweak in my case, AB couldn't change it at all on the boards without accessible gpu registers) and for example GPU-Z reports the new vcore you set but it doesn't change/or simply goes to the next "step" while still displaying the wrong vcore, I still don't believe there are 5870s running at 850Mhz with 0,899V, why I started testing wth was going on in the first place! :p

Back on topic! I've tested my only 5970 (ref board, all changes done by bios flash and editing the GPU registers) and it does have "steps" but seems to be around 0,13V (0,899V, 0,912V, 0,925V, reverts to these values when you set 0,9 0,91 0,92 etc) tested all 3 and both power usage and max stable frequency changed by about 3-5W at same speed and 10-15Mhz for how high it could go.

Edit, might add i'm currently running my 5970 at 0,899V and 625/300, can do a bit higher but it's mostly to be sure about 24/7 stability. The card pulls around 145W from the wall on a 80+ bronze psu.

So 680 @ 0.95 & 750 @ 1.0 are good starting points?

Too bad lower voltage isn't possible.

Yes, i basically have 3 heat modes:

800/300/1.05 
760/300/1.0  note: 760 !750
680/300/.95  will run really cool even on warm days


i did the mem at 220, but I was informed that it wasn't worth it. but it did run stable

Yesterday tried 0.95V 710M/150M setting on 5970 and after some hours one of the GPU dead, seems 700Mhz could be run stable, and at 1.0V 750Mhz is stable

agreed.  i go down to 680/300 when v @ .95

afaik, the 5970 does not have that 'step'

only  .95, 1, 1.05

5970 voltage steps tested at 650Mhz:

0.000-0.950 xxxW
0.955-1.000 xxx+8W
1.005-1.035 xxx+16W
1.040-1.050 xxx+19W

I think xxx is around 200w, but no precise figure since this is a test from mixed gpu on board

If you run 4x5970 how do you get the second core of your card that the monitor is connected to overclock? or at least underclock ram.

In my case under windows this is not a problem, because I can just change my monitor to one of the 5870s I got on x1 extender, but under Linux that doesn't work. And no I can't really reorder my cards so that the 5870 is the one that is #1.

Not connecting a monitor probably works for Linux, but I kind of need my monitor! If you know how to change which card shows desktop or know how to make the OC work for the second core please help.

use cgminer!

  If you're running the latest drivers, you should be able to show all the OC sliders in Afterburner for all cores on the card (just go to settings > one of the 4 cards in the dropdown).  You can't change the fan speed for them all but you can still move the clock sliders.

  Update on my end.  Diamond told me they could trade me two 6970s for my cards dying.  I'd have to pay extra to step up to 7970s.  Oh well even if I lose some hashes, having a running system beats none at all.
