Title: [WTS] 6990s Post by: Tril on May 15, 2013, 04:38:08 AM Selling qty (2) Radeon 6990 cards for BTC. They've been mining since fall 2011 but I kept them around 70 degrees C almost all of the time, regularly cleaned dust out, and never overclocked them.

Title: Re: [WTS] 6990s Post by: dethdeks on May 15, 2013, 04:58:35 AM will these still game and how much you asking for them? also do you ship to canada
Title: Re: [WTS] 6990s Post by: flyingmonkeycrap on May 15, 2013, 10:49:18 PM I'd like to know your asking price as well as get some pictures of the cards. Definitely interested. Thanks

I'm sure I can ship to Canada. Start bidding at 3.5 BTC each. Will take highest offers a week from now. Thanks for reading this thread. Title: Re: [WTS] 6990s Post by: notaek on May 17, 2013, 11:50:38 PM Two 6990s running at 350kh/s? That's worse than awful. Yeah... Considering he has two different cards that has to be some sort of GPU config error. They are at really low temps too so they could probably get a good ways beyond 400khps per core with a proper conf and some overclocking. Title: Re: [WTS] 6990s Post by: flyingmonkeycrap on May 18, 2013, 01:02:35 AM well I'll start you off with 3.5 BTC each
Title: Re: [WTS] 6990s Post by: notaek on May 18, 2013, 01:04:09 AM well I'll start you off with 3.5 BTC each For which one?

Title: Re: [WTS] 6990s Post by: computerparts on May 18, 2013, 01:12:12 AM Two 6990s running at 350kh/s? That's worse than awful. You do realize that 6990's are dual gpu cards right? Each gpu is running 350kh/s. So each card is running 700kh/s which seems reasonable to me considering the low temps and no overclock. That price is terribad though considering 7970's can do the same and be had for less. Title: Re: [WTS] 6990s Post by: ssateneth on May 18, 2013, 06:13:50 AM IIRC, 6990s are clocked in a 880MHz per core stock. His miner is not configured well. He should be getting ~394 mhash per core at stock speeds. No idea for ltiecoins, probably he same # in khash. I don't mine scrypt.

These comfortably overclock to 900MHz and give you ~404MHs per core using CGMiner with Catalyst 13.1. ~350MHs seems about right for 880MHz... I think... Title: Re: [WTS] 6990s Post by: ssateneth on May 18, 2013, 11:27:13 PM 20 mhz gives 54 mhash? I think your math is off...
Title: Re: [WTS] 6990s Post by: Xian01 on May 18, 2013, 11:50:18 PM 20 mhz gives 54 mhash? I think your math is off... Try it on either a 6970 or 6990 and see your yourself. I have a couple 6990s in my farm running at those speeds. Title: Re: [WTS] 6990s Post by: notaek on May 19, 2013, 12:28:12 AM 20 mhz gives 54 mhash? I think your math is off... Try it on either a 6970 or 6990 and see your yourself. I have a couple 6990s in my farm running at those speeds. In my experience with 6950's, More than a 20 MHz boost is required to add a 54mhps speed increase Title: Re: [WTS] 6990s Post by: Xian01 on May 19, 2013, 01:19:05 AM https://i.imgur.com/b5F8Y1k.png
Not sure what to say, homies. GPU 0 and 1 is each core of one of my 6990's, and GPU 2 and 3 are each core of the 5970 in that one rig. 20 mhz gives 54 mhash? I think your math is off...

Anyways, those mhash are more or less what you can expect at those core speeds.

I was referring to OP's poor performance with his due to a bad miner conf. Regardless of what your conf is though, a 20 MHz boost isn't going to improve hash rates by 54 mhps :-\ Title: Re: [WTS] 6990s Post by: Beaflag VonRathburg on May 19, 2013, 04:49:57 AM ^ The intensity was just turned down to 6. Makes a huge difference even at the same clocks.

If so - where did you get it? Pretty cool.
