Title: What is a good setting for SAPPHIRE Radeon HD 7970 GPU? Post by: bitcoindude80 on May 17, 2013, 03:57:41 AM I'm currently getting only 650Mh/s with this card (http://www.newegg.com/Product/Product.aspx?Item=N82E16814202008) with cgminer.
Can this card go up to 700-750Mh/s? Title: Re: What is a good setting for SAPPHIRE Radeon HD 7970 GPU?

If you can keep the vrms below 80c, raise the gpu 5-10 mhz untill it crashes.. The only non heatbag Sapphire gpu Ive seen was a reference hd6870. hmm I wonder why ?! The Sapphire 5850, 7870 and both 7870xt's have stinky hot VRMS thx to the stinky cheap heatsinks.. :/ Title: Re: What is a good setting for SAPPHIRE Radeon HD 7970 GPU?

getting the same numbers 1143clock 300memory stock voltage you can push it up to 1153 and get it up to 660, but it will crash after 20 hours or so you can go higher if you can provide it with cooler air i live in the tropics |
