Yeah I know, was just being my sometimes sarcastic self ...
My best option is to run the Piss outta both of them & if & when they go bad hope to get 6990's back, Sparkle did that on some 460's I sent into them for bad fans. They replaced all 4 460 Cards with 3 470's & a 480 ...... I can't really complain since the Cards ended up only costing me $200 apiece ...
Lol, reading this thread has educated me a bit on ati/amd cards. I've always gone with nvidia for no objective reason (I love my gtx 590!). Well, there was that old ati x300 that died because the fan melted...
I'm also still happy with my 6970, which is currently giving me about 350k at Moo!
Hmmmm ... that may have something to do with why I went through 6 of them in about 19 monthsOriginally Posted by STE\/E
BTW, for those that don't know, the 5850 is a "brain dead" 5870. It isn't as some assume a binned low performance 5870 chip. It IS a 5870 chip that has had 1 bank of the processors disabled.
If you use something like MSI AB and raise the voltage to 1.16V (the same as a stock 5870) then you can clock it up to 950 MHz just like a 5870. Did that on 2 of them for a couple of years until the fans finally crapped out.
Am I pushing the 5870 too much here?

imo, no. I ran my 5870 at 984MHz during the first BOINC Pentathlon. 100% stable and didn't require a voltage tweak, though i know not everyone will get the same results.
After the Pentathlon (which lasts 2 weeks) i backed it down to 950MHz where it ran for over a year. The card still works to this day, though it's at 900MHz because i have yet to vacuum the dust bunnies out of it lol
No that isn't pushing at all. Definitely good to 950 day in and day out.
I would strongly suggest dropping your memory clock down to 425 MHz and it will probably drop your temperature 5C or better. Collatz is the only project that high memory speed helps and since it uses single precision math the temperature doesn't rise with the increased memory clocks.
Hmmmm, tried to move the slider on the memory clocks, and the lowest it would go was 1000. Another way to do it?
It should go much lower. Try the following....
Reboot into safe made (by tapping F8 key towards the end of POST test, before the Windows Logo appears) and log in. This will reset all Windows boot cache settings.
Reboot and log in. Shut down BOINC Manager. If you are using 3rd party OC utility like Afterburner shut it down also. Now try adjusting Mem clock.
Well I sold 2 of the 5970's a few days ago & a 470 yesterday & a 570 today for a total of $1400 v the $1200 for the 4 5970's I ordered so I've more than made up for the 2 5970's I've kept with about $150 spare change to boot after Shipping charges ...
I think the CCC only allows you to go so low, not near as low as the MSI Afterburner lets you go ...
