I hate to sidetrack the thread some more - but is that a windows desktop gadget (in the picture) that acts as a watt-meter? If so - where did you get it?  Pretty cool.

Desktop widget for the Cyberpower UPS I have the rig plugged into.

Thanks - I like it.  Grin

^ The intensity was just turned down to 6. Makes a huge difference even at the same clocks.

I can't believe I missed that...

Missed that. Would perfectly explain it.

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...

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

Yeah, your pic is an example of what is achievable with a 6990.  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  Undecided

So I was right Tongue

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

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...

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.

well I'll start you off with 3.5 BTC each

For which one?
The gigabyte one I guess....Doesnt really matter to me though

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.

Pics of the cards?  CGminer screenshots?

Quote from: dethdeks
will these still game and how much you asking for them? also do you ship to canada

Yes, they can run games; there are no problems with them.  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.
