Now I have fixed a problematic pci-e extender, my 5970 can run 800/300 at stock V under 55c  (open case temp 5c) for 40% fan, but I only push it to 97%-98%

5970s undervolted mostly because of fear of overheating or sudden death

core: 750Mhz
mem: 250Mhz
Vddc: 1.000V
Temp: 66ºC
Hashrate: 690MH/s

i have one that won't mine at 750 core so i leave it at 725, the rest is the same , oh the hashrate drops to 666MH/s

I have been running some of my rigs @ 1.00V.  Nice drop in power consumption.  As FPGA miners start making the price/difficulty ratio to fall (network gets more efficient) I think the 5970s are a great card because you can keep dropping voltage (and clocks) to boost efficiency and expand their longevity.

The bad news is that you make less gross hashes the good news is that you can keep mining even with really old hardware. Smiley

man i never thought about that before, what is the lowest (highest?) undervolt you have achieved? and at what clocks?

between 800/193 and 850/193, stock voltage, in water cooled system, temps always under 50oC, in other one, highest I've seen is 72oC, fan maxes out at 75oC, hasnt gotten that high yet.  avg fan speed probably around 50%

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

My 5970 that has been running since June: 68.5C / 65.0C, 100% Fan, 830 / 280 and 825 / 280 at 1.05 volts.

My 5970 that has been running since this January: 54.5C / 51.0C, 90% Fan, 810 / 280 and 830 / 280 at 1.05 volts.

I want to get cgminer running with autofan and autogpu again, but phoenix was easier with BAMT.

It's more than that.  When I setup cgminer, the rig was really unstable.  Even with stock clocks.  Better to just use phoenix and have no more downtime,

that's odd, my experience is the opposite. Phoenix was utter crap for me giving me like 30% rejects, when i started using cgminer it all became stable

With BAMT that is.

Linuxcoin always worked better for me than BAMT

Now my 5970 stay at 770/150/1.0 stable with 42% fan and 60C at outdoor temp 10C

Daytime (windows open)...

810/180 @ 1.05v = 370 Mh/s

Nightime (windows closed)

755/180 @ .99v = 342 Mh/s

Try to keep temps under 70c and fans below 65%...

Already replaced the fans and reapplied TP on 2 of the 3 cards...
