My 5970's don't really run that hot 65c-70c is about it, Winter or cooler weather here now so I can control the Temps in the Garage where I have the Box's by opening or closing the Door a little, I also blow some of the warmer air into the house to try & save on heating costs for the house during the winter ... Will have to see how hot the 6990 run's, if to hot may have to get something like that ...
That is some serious fanning, I think I could feel my hair moving. 3:-O
I know a guy who bought one of the those fan coolers for his 5970 and he loved it. That is until he added a 2nd high end card to the case and things started getting pretty warm. That cooler doesn't vent out of the back, it dumps all the heat from the 5970 into the case. He went back to stock cooling on the 5970.
Your results may vary :))
I had 4 GTX 460 Sparkle Calibre's with those types of fans, cooled real good until they either quit running or a fan blade broke off ... :| ... But they replaced them with 3 GTX 470's & a GTX 480 so I can't complain ... $-)
Yeah, for that Arctic Cooler you need a case with very good air flow. One with ample exhaust to match the air being pulled into the case. Which has been a real challenge for the majority of cases out there.Quote:

Probably must be something to do with changing the CPU Usage to 3 & then back to 4 again, still ran the Wu's in the 14-15 Min Range running 3 CPU's but now that I've gone back to 4 CPU usage the Wu's are taking 3-4 Min's longer ... :/ ... Will change back to 3 CPU's if the times don't come down soon & see what happens ...
What % GPU utilization is it showing for each GPU in Afterburner? Try with 3 CPU and then with 4 and see if it makes a difference in the loading. If the GPU is still running at the same clock speed, then the difference in completion times should just be a factor of loading percentage. Obviously as cruncher we want the highest % loading possible, which seems to be 99% on the GPUs.:cool:
Hard to say really, it's all over the place, up down 1 GPU Core Idle then both running ... It was okay until I changed to 3 CPU Cores running then back to 4 running again ...
Huh. Something is definitely not right. That's what it looks like on Kat's rig with the crossfired 4870s if I don't reserve 2 cores. Try dropping CPU cores in BOINC until the GPU % utilization is pegged at 99% solid on both of them. Then look at your times. If the times go down like they should, then it is not a GPU problem, but something that is bottlenecking the GPUs.
Seems to run the Collatz Wu's okay, thought I'd run some to see if there's a difference in Cores, running @ 900 Core & 1.25v & running all 4 CPU Cores, not the fastest thing but does okay & it's consistent in the run times too as I up the Core Speed ... Maybe it just doesn't like the MOO Wu's, or at least not like to be overclocked running them anyway. I e-mailed Newegg to see what they say about returning it. I can make a decision after Monday next week when the 6990 is due to be delivered ...

Ah, OK. Yeah, will be interesting to see what they do. I am still waiting for them to decide whether to refund me or see if they can come up with another card from somewhere. I'll let you know what route they do for me, so it may help you decide too.
On a good note - what with your findings while running Collatz, and Philly's problems on moo with (2) 5870s, I am beginning to wonder if the problem isn't Moo! related? Or at least mostly so. I think Collatz is coded very well, and doesn't seem to have a problem, so that is a little telling, isn't it?:confused:
Have the HD 6990 chewing on some MOO Wu's to see what it can do, running @ 880 Core & Stock Voltage ...
Still haven't heard back from Newegg on possibly returning 1 of the HD 5970's, trying to Live Chat with them now ... :rolleyes:
EDIT: Just talked to Newegg, their going to send me a Prepaid Shipping Label & set me up for a Refund, I have 7 Days to ship back if I want too ... :)
Might as well push it and see what you can get out of it at this point.Quote:

Thing is, you got one card out of the bunch that was good - probably one you sold was good too, I'll bet they are like 50/50 on the HD5970 cards after seeing what we've all went through on them now. So...I'd be real tempted to return it for a full refund, unless you think it is worth it to keep it.
I can guarantee that I won't be looking for any used 5970's.Quote:

The 6990 seems to be running okay so far, Times in the 14-15 Min Range with a few sub 14's ... So with the 2 I sold the 1 I'll keep will only cost me $100, can't kick about that ...Quote:

If I do find some, I guess I'll have to build something for them, I don't currently have anything to put them in.
Decided to just keep the extra 5970 & new 6990 for now, put them both up for sale on my Amazon Account & if they sell fine if not I'll use them till they possibly do. I can make money by selling the 5970 rather than return it & the 6990 was going to cost me too much to return with restocking fee & shipping fees so I think I can sell it & possibly break even on it anyway ...
Sold another 5970, so the 5970 I have now was Free :D plus a little money in my pocket for the 3 I did sell, going to try & sell the 4'th one too I think, just not happy with the performance of them. That plus with the new ATI Cards coming out in a month or 2 I'd rather wait & see what their like. If it don't sell no big deal sinc it's Free anyway ... :cool:
Holly Toledo, that is just crazy.... So when you sell the last one its all profit. >:)Quote:
