interesting how those with 5970 clocks at 850, or 930 seamed to have disappeared... I would love to run mine at that, I have 21 of those cards.. anything over 820 is unstable for me.
w/ memclock down to 190 I can get 835 on 12 5970s. I have 4 watercooled and I can push all of them to 865 w/o problem except one. Temps are <50C but anything higher than 865 requires more voltage. I had them 100% solid at 880 watercooled but overvolting doesn't seem worth it w/ current prices. The GPU driving the physical monitors can't be pushed beyond 830 without lots of instability. So yes higher clocks are possible.

I upped mine to 825/350 so far so good.. i guess when I first started using them, I had trouble with mems less then 420, but it must have been other issues. each core getting a solid 370-372 now txs

I have a rig with three 5970s which just came up and which is now on a 24-hour shakedown cruise at stock engine speed (725), 190 mem speed, before I subject it to overclocking. I'm OK with software but hardware is magic to me. I'd appreciate a brief tutorial (a sentence or three) on how the voltage parameter relates to the other ones.

burning them in at stock is a good to do. I also used them for a while at lower clocks. I probably will not mess with the volting. happy to let them cruise at 745Mh per card

I just have one 5970 that is unbranded (so Dell). I almost bought a second but then they became impossible to find.
I first had it set to 835/300, but it crashed after a few days. It's been really stable at 830/300 since June on stock air cooling in an ACd server room so it never gets above 75C with 85% fans. It's in a spare antec 1200. I would love to build a custom case for the nerdgasm, but I have other projects to work on.

The box I upped from 820 to 825 has died about 15 hours after pressing the accelerator... I will probably back them all down to 820.

I didn't think I could get the mem down to 350, so putting it at 300 will definitely help. I dont think it is the heat of the main GPU that is the problem, I suspect the VRM

My three 5970s ran OK for a day at 800 engine, 190 mem after the previous OK day at 725/190. So I upped the engine speed to 820. After a short while one of the cores hung. Should I...
(a) Try again with the other five at 820 but the one that hung at 800 (810?); or (b) Set them all back to 800 (810?) and be happy; or (c) Something else?

each set of cards is different for me.. I have one rig running stable with them set at 825, but miner9 will only hold the 800. still get about 2850Mh from the rig at 800

I see you have overvolted it (alot) and have the fan at 100%, may I ask what hashrate your getting? and do you know how much power your pulling at the wall? this is an old pic, I use cgminer now, but when I first set these rigs up, I would get 2900Mhash pulling 1190watts at the wall (2 sea sonic 750 gold psu's) https://plus.google.com/u/0/photos/112408294399222065988/albums/5658727447810944545
