Title: 7950 Model? Post by: nookiegirl on April 11, 2013, 02:08:53 PM It seems that are lots of different ATI HD 7950 models out there.
Which are the criteria to look out for when buying a 7950 suitable for BTC and LTC mining? Title: Re: 7950 Model? Post by: Shaban on April 11, 2013, 02:20:47 PM http://www.newegg.com/Product/Product.aspx?Item=N82E16814202006

With a target temp of 62 in cgminer, the fan is always at 0% (about 1700 rpm). Make a big differnce if you rig is in your office where you have to work and game too (I work from home).

For the 7950 card, what are good (recommended) values for core and memory clock as there also seems to be quite some difference? I do mean the stock clocks, not the ones you have already customized. Title: Re: 7950 Model? Post by: btcfanx on April 11, 2013, 02:54:06 PM I think there's no difference between different vendors of HD 7950. All of them use standard PCB board. The main difference is in cooling system and (maybe) in BIOS.

Title: Re: 7950 Model? Post by: nightminer on April 11, 2013, 03:32:00 PM I prefer to lock the card in its specs as set by the manufacturer. For the asus card I use these extra options for cgminer
Code: --auto-fan --gpu-engine 800 --gpu-memclock 1250 --temp-target 64C The ASUS is clocked a bit slower (800Mhz) than the saffire, but I get a decent 425Mhp/s at intensity 9 without the card breaking a sweat. That and I can still sell the card on the very active second hand market 6 months down the line without feeling bad. |
