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.

You may want to try dropping memclock further. Then again 820 vs 825 = <1% so it might not matter.

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 have my 5970 running at 830/300 w/ stock voltage at 63c and 3800 RPMs

No problems....yet Wink

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.

fair enough... 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

send them to me i would gladly run them at those clocks

ok after a little bit of playing with both afterburner and cg miner i got my 5970 to 920/150 and the voltage in afterburner is 1149 with temps at 67 degree Celsius i haven't taken these apart but i think i am going to do so in the near future at-lest the one bc the vram i think is at like 106 when all the rest are sitting at about 90 so i think it needs new thermal pads and hell while im at it new thermal paste anyone know of any good thermal paste and pads to use?

I'll get some validation soon Jimm. I am running these rigs in a very cold basement right now with no heat on the east coast. I am SURE they won't run at 850 once it gets warmer.

They do have to be reset fairly regularly though at those clocks, about every 12 hours, so not very stable yet. I'm building a rack of fans to blow into the cards and see if that makes it stable longer. For now I clocked them down to 800/300 and they have been running for a couple days without problems mining 24/7.

I didn't want to tinker with anything due to the holiday and also because we caught some long blocks in our pool recently. I mine at Eclipse also. I figured I didn't want to power down my rigs until we chewed through that last long block..lol.

No lies I got two 5970 running at 930/500

you must have overvolted them... pics?

I hear ya, but my purpose in doing this is beyond maximum bitcoin mining potential. I enjoy tweaking hardware and learning. Also, I did get the TIM and pads properly installed last night and it worked great.

I'm running two 5970's at 850/300 at max 58c and that is without the pci extenders and such I will eventually use on the custom case I'm building.

So to me it's worth it just to learn. For those who want maximum bitcoin production you guys are absolutely correct, just set them up, slight OC and go.

I also build custom gaming PC's on occasion so this is all useful for me to learn. Those machines are all about max potential and you never get that with stock cooling, etc.

a 5970 running 850/300.
1. how long?
2. pics or it didn't happen

Quit goofing around and leave the machines up and mining, I guarantee you will make more plopping together a stock system and leaving it alone than you could make up for the downtime trying to tweak overclocking and installing drivers and different software. Just use some big case fans or pull the systems out of the case.

OK, dual power supply adapter cable.

Ok, so I'm a noob with using multiple PSU's, does that matter? I'm here to learn and improve and possibly help others. The title of my post was not " The definitive guide to using four ati 5970's on one mobo"

Thanks for the constructive advice though.

I didn't get into this to make money, I enjoy hardware as a hobby.

My advice: dont tinker with things you dont know or not sure about.

Leave those cards intact, instead focus on custom box to drive cool air to the cards. More efficient that way.

COMPLETELY agree with this... KISS.

open case, risers, little fan blowing air from the back .clock 820/420 -- 1200 watts can get you 2900Mhash at <75C out of the box...

dont over think this stuff, and dont overclock too much, put the cards on cruise control and go have dinner with your girl!
