For 24/7 I can't go more than 1080 at 1174mV, and that was when it was -10'C here, now it is +10'C so I doubt that I can do it stably.
I am curious too, I might try 1.2V but I'm a bit scared, and I doubt I'll get more than 1100MHz, and my PSU GX750 is fucked up it gives 11.8V with just 1 card.
I should try it on the AX1200 but i run 5870s on it.

btw all of this is useless now, because of efficiency - I run my 5850 at 1V and around 900/300MHz depending on the card

Nope dude I'm from Bulgaria, and next week here there will be temperatures of -7'C to -10'C so expect some more printscreens from me Smiley
No nitrogen just cold air. There are vids of my rigs on YouTube:

I'm using SDK 2.4 maybe SDK 2.1 may give me 1-2 more MH/s and I have a week CPU, so 1-2 MH/s lost there too.

For the record.  My rate of 461.1 MH/s was also set with air cooling.  I went as far as replacing the standard fans with some decent custom ones but no liquid was involved.

king_pin:  Hash rate aside, 1080 MHz at only 1.174V is impressive! (damned impressive if I'm correctly gathering that this card is simultaneously driving the desktop).  How stable is that?  The big advantage I had over many other miners was having no GUI (my screenshots are just ssh sessions in terminals on another machine) and I bet my good card would have struggled to do that if at all.

Honestly, I was uncomfortable taking my card beyond 1.15 V but decided to try it briefly for the purposes of setting records and learning more about my cards.  I eventually set my card to 0.9875V, 890 MHz core, 300 MHz RAM, which was giving me 373.1 MH/s, and got more involved with pools (about a month before Namecoin merged mining came out).  I preferred this as it was much kinder to my cards and was more profitable (with my second card set a little slower my rig drew 300W at the wall, so 2.43 MH/J).  I never had a crash with these settings.

No no she isn't the desktop one Smiley
But I have one 5850 which is the desktop card and is running happily at 985/300/1049mV so I think she is my most impressive card. Smiley

Ah good.  I was prepared to grill you for details on the 1080 MHz setup, but with no desktop generating noise and distraction like a 3-year-old on holiday, it's a plausible rate for a good card given the overvolt.

As for the desktop card: running two differently demanding tasks stably, 24/7, with a serious overclock is already a considerable achievement.  Doing this with a mild undervolt?... Cheesy.  She's a gem; long may she live.

hmm, i've never owned a 5850..

i messed around with that 5870 some more since it actually got cold again here for a bit...  i started running into problems not w/ stability but with "hardware errors",   maybe 2 or 3%?   this around 1120 clock

Rumor has it all started when he resurrected a thread that dates back to the big bang, that then sucked him in ripped his entropy into pieces, spreading clones of him all over time and space. All of them doing the same exact thing, resurrecting old threads, and all without him knowing why or even where he even came from nor who he is.
