Title: Best mining GPU? Post by: SirJMD on January 03, 2012, 11:49:59 AM So.. which GPU gives the most bang for the buck? I currently have a HD5970 which puts out roughly 600 Mhash/s.
Is there a comparison somewhere? Title: Re: Best mining GPU? Post by: legolouman on January 03, 2012, 11:51:49 AM https://en.bitcoin.it/wiki/Mining_hardware_comparison
the 5970 is a pretty awesome deal if you paid like $300-$500 for it. The 7970 is destined to be the best card for mining. Title: Re: Best mining GPU? Post by: stevegee58 on January 03, 2012, 12:11:02 PM If you check the "Single Card Setups" section in https://en.bitcoin.it/wiki/Mining_hardware_comparison#Single_Card_Setups (https://en.bitcoin.it/wiki/Mining_hardware_comparison#Single_Card_Setups) you'll see a column for Mhash/s/$. The 6750 or 6770 are the cheapest, yet give fair performance of around 200 mhash/sec.
I'm getting a 6770-based card first. Title: Re: Best mining GPU?

The 7970 is destined to be the best card for mining. Cool, i paid around 350 USD - so it seems like an OK deal. Thanks for the link! Title: Re: Best mining GPU?

At below $400 this is pretty much nothing that beats the 5970 in MH/W or MH/$. For used cards the 5870 is slightly cheaper (~$150) than 5970 (~$300) but the higher density of the 5970 makes up for that IMHO. Title: Re: Best mining GPU?

Cool, maby i should get a 2nd one then :) Im currently using BitMinter Client - is there a better miner out there? Title: Re: Best mining GPU? Post by: DeathAndTaxes on January 03, 2012, 06:52:14 PM Bitminter is pretty good. I have found slightly better results (and more customization) w/ cgminer
Title: Re: Best mining GPU? Post by: SirJMD on January 06, 2012, 12:02:47 PM Bought another 5970 :) Lets see what this can do.. any advices on the settings for the BitMinter?

Bitminter doesn't really have a lot of customization. It is a very good miner made by the pool author for "casual" miners. If you want max control you should look at cgminer. Try adjusting core clock and memclock. I find 800/300 a good place to start. I run most of my cards at 820/190 some slightly higher, some slightly lower. Each card is unique in what it can handle. Once you get a miner stable for say a couple hours they may still go dead after days. Bring the clock down slightly. You will find the final clock which is stable 24/7 for weeks (sometimes months). I have one rig going on 48 days of uptime (I haven't even upgraded cgminer because I want to see how long it can go). Barring no power outages I think it could run until summer w/ no downtime. :) Title: Re: Best mining GPU?
