Title: Club3D 5870 OC Edition - best performance yet? Post by: timmmay on May 25, 2011, 04:02:34 AM Hi guys
I've just picked up 3 x Club3D 5870 Overclocked edition for $260 AUD each. This is the config I have them running at without any tweaking of the miner: OS: Windows 7 Driver: Catalyst 11.5 SDK: 2.4 GPU clock - 1000mhz Mem clock - 900mhz Fan control - 100% These settings have been applied using the Catalyst Control Centre - AMD Overdrive So now for the results! 420MH/sec with poclbm.exe -v -w128 Temp: 56C !!!! (this part just blows me away) I'm about to start playing around with Phoenix and see if that gives me any better results! Title: Re: Club3D 5870 OC Edition - best performance yet? Post by: acamus on May 25, 2011, 04:06:53 AM thats very low temp, come back in 8 hours without touching anything. we'll see about that 56c

The highest I got, using windows(windows tools seems to give me higher overclock) was the following. Tools used: -AMD GPU Clock Tool for HD 5850/5780 -MSI Afterburner HD 5850 at 1150 mhz gpu @ 1.275v / 1250 mhz mem (stock voltage) GPU temp @ 100% furmark testing maxed out at 62c (airconned room, no case) crunching speed: 445mhash/s Title: Re: Club3D 5870 OC Edition - best performance yet? Post by: timmmay on May 25, 2011, 04:14:59 AM Yeah I'm expecting it to get higher but they haven't moved yet. I'm running each in seperate boxes at the moment and am planning getting a few more tomorrow in a single box.
I'll give the AMD GPU Clock Tool for HD 5850/5780 a try and see what I can push out of it! Title: Re: Club3D 5870 OC Edition - best performance yet? Post by: Clipse on May 25, 2011, 04:15:52 AM Ye these ATI cards are a real bang for your buck considering hashing :D
Title: Re: Club3D 5870 OC Edition - best performance yet? Post by: timmmay on May 25, 2011, 04:24:39 AM So I tried the tool and could adjust the clocks fine but it immediately set the fan control back to auto and the temps jumped up. I've set it back with AMD Overdrive and fans at 100%
Do you know of any fan control I could use? The GPU clock tool doesn't appear to be able to handle the fans. Title: Re: Club3D 5870 OC Edition - best performance yet? Post by: Clipse on May 25, 2011, 04:30:11 AM You use both tools together, GPU tool for voltages and afterburner to adjust fan speed.

Post by: Basiley on May 25, 2011, 04:32:49 AM Ye these ATI cards are a real bang for your buck considering hashing :D in fact, they amazingly good for virtually ANY DP-precision computation.Title: Re: Club3D 5870 OC Edition - best performance yet? Post by: timmmay on May 25, 2011, 04:53:09 AM You use both tools together, GPU tool for voltages and afterburner to adjust fan speed. Awesome thanks. It just locked up on me trying to go over 1000 so I think I might just leave it at that :) Definitely a great bang for buck card. I thought this to be important considering the estimate difficulty rise of about 80% in 2 days! Title: Re: Club3D 5870 OC Edition - best performance yet? Post by: timmmay on May 25, 2011, 05:24:58 AM Now I'm using Afterburner for all settings.
1000mhz GPU 610mhz memory default voltage Still pushing 420MH/sec @ 60C now :) Title: Re: Club3D 5870 OC Edition - best performance yet? Post by: Clipse on May 25, 2011, 06:11:05 AM Ye, depending on your budget any of the following is among the best bang for buck on the market:
HD5830 , HD5850 and HD5870 |
