    Out of curiosity...

    Thinking of putting 2 5850's from ASUS up for sale.

    EAH5850 DirectCU 1 GB GDDR5 flavour.

    Plan to upgrade...

    Thought I'd ask here first.

    Fleet? Huh?

    Not mine but a picture of someones bitcoin operation. That would be considered a medium sized operation too. I couldn't find any at the moment but I have seen pics of entire warehouses full of amd gpu's.

    Are they all Crossfired or something?

    I would not want to be responsible for the noise of 12 reference AMD cards or their power consumption. :eek:

    I see crossfire links but you can see what I see in the picture. I know crossfire often did not help in bitcoin mining.

    So yea I got a 7970 being shipped tomorrow, what points should I expect to see out of it over my 6950's?

    100-130K PPD is the typical Tahiti range.

    That's amazing, congrats. I seem to average right around 100k per card with my 2600k, possibly held back a little by CPU. Can't wait to see you with your new card rocking the ppd!

    Once the 7970 is in place I will most likely put up the 6950's for sale. I have to get my new front suspension for my truck.

    Ahh yes, back when I was representing Finland... :D
    I think you're being a bit optimistic there--I'm getting ~80k from the HD7930 and just over that from the HD7950 (which I realize is CPU-bound). KieX's two HD7970s that I'm running pull down 100k a day, but rarely any more than that.

    True, I guess it is also dependent on how many WUs are queued up and such. I got ~110K from all 3 of my machines today, one of which was offline for 12 hours and the other two saw several hours of downtime as well, as I swapped coolers on two of the cards today.

    Speaking of cooler changes, I took the Windforce cooler off my poorly overclocking Gigabyte 7950 (replaced it with my XFX 7950 cooler which works fine for crunching) and put it on my 7970 along with a ghetto VRM heatsink as I wanted to have my best card at home and running cool. Now all 3 of my GPUs are crunching at normal temps without being too loud, and my 7970 should hopefully play Skyrim overclocked at not 90-95c anymore. :slap:

    Best ppd "max output" estimate to use for the 7xxx Radeon's is 5-5.5k ppd per 100 SP's

    Example:

    GPU--- SP's--- low ppd--- high ppd
    7770--- 640--- 32--- 35
    7850--- 1024--- 51--- 56
    7870--- 1280--- 64--- 70
    7870 XT- 1536--- 77--- 84
    7950--- 1792--- 90--- 99
    7970--- 2048--- 102--- 113

    ppd can vary based on gpu speed, cpu speed, cores/threads so these are soft estimates and can likely vary by 5-10% plus or minus

    ppd seems to run linear with SP count for those gpu's - most of the data I've seen falls into this range

    FYI- did an edit on that post to fix the SP count on the 7870 :eek:

    I'm sure we'll find out where Bonaire ranks in a few weeks, perhaps? Hopefully someone buys one and shares their experiences. ;)

    I can get 130k out of my 7970 overclocked to 1250mhz.

    I found a bigger fleet. I am counting 75 gpu's? I know there is bigger out there still.

    Played Skyrim on my "frankenforce" 7970 at 1150/1500, and the card still gets into the mid 80s, and reached 90c at one point. About 2/3 of the way into my session, I noticed the center fan on the Windforce was making a huge racket and is now dying (or may be possible to save with oil). Quite annoying considering I purchased the 7950 Windforce card brand new maybe 6 weeks ago. :banghead:

    Got the contest Visiontek 7770 card installed after a ton of hassle (my dad's ASUS M4A89GTD PRO/USB3 is quite a weird motherboard) and I noticed that pretty much all the previous GPU WUs failed with the XFX 7770 (13.1 drivers), so I updated the display drivers to 13.3b3 and I sure hope I get WUs again soon so I can test the setup with both cards. :(

    Try the 12.6 driver if you continue to have trouble- that's the most trouble free on my systems.

    Hi! I'm from the Internet
    I agree with Norton here. The 12.6's is all I use nowadays.

    I'm sorry to hear that you're having issues with it--but I would try the other drivers, I think that's what I'm running w/ success :toast:

    Server is back up and WCGing again, had some down time when switched to water and then more when the pump failed now back up to 100%

    Okay, it seems that DistrRTgen GPU WUs take longer to complete than HCC GPU WUs, while also loading the GPU more, judging by the "gaming" temps I get on my card. However, the CPU is being loaded so low by those units, that the CPU does run two normal WUs at once (like when not crunching on the GPU). BTW, I did not configure this in any way, it was "decided" by BOINC automagically.

    I really wish that I knew we could count on more GPU work for WCG--I've sold several hundred dollars more in systems this week and want to buy more crunching power, but for just a month and a half of known GPU work it doesn't seem wise :ohwell:
