Title: [WTS] dual-GPU 6990s - only 10 left!
Post by: mrb on May 09, 2012, 06:13:45 PM
I said last month I would have tons of 6990s for sale in May... Well here they are!

  • Cards in excellent condition, used for mining in datacenter-like environment (no dust, cool air)
  • Come with full retail box + manual + video adapters + sales receipt for warranty
  • Each 6990 mines at 691 Mh/s stock clock
  • I have excellent reputation (check bitcoin-otc rating in my sig)
  • I accept payments in USD or BTC
  • I can ship anywhere in the world, from Los Angeles; buyer pays for shipping

I also have a single 5870 I would like to get rid off, never been used for mining. Sold!

Email me at m.bevand at gmail.com, or reply to this post (no PMs please -- too inconvenient), and make me an offer: quantity you want, price, etc.

As you saw in my previous post ... I will have about 1000 dollars to spend on BTC.  How many 6990 can I get with that?  Would it be more smart to buy 6990 a couple of them or a whole bunch of 5830?  I may be possibly having 1500 range.

Thank you.

iSellBitcoins: for guidance, a fair price is roughly $400-$500 per 6990.

yochdog: offer noted, thanks, I'll think about it...

check_status: the 5870 has been sold already, sorry!

If I have not replied to someone's email/message, it is because the offer was not interesting enough.

I still have 6990s available for sale. Contact me, people, and make offers!

How many do you have left and how much for the entire bundle?

Thanks.

I am dead serious.  I will just have to ask my loan shark.

Come on guys, I ask you to make offers, but you never do and always ask me to quote a price... that's no fun! :)

Alright David_Benz... let's say I can sell you 15 cards for 1190 BTC. I will save you negotiation time, this is my rock bottom price.

Okay and that would be about 12 Ghash, right?  

How big of PSU do I need to run 2 of those on one machine?

Thanks.

Thanks.

At stock clocks, 10.5 Gh/s.
Overclocked, sure, many people do 770 Mh/s per card, so 11.6 Gh/s.

2 non-overclocked GPUs (but mem downclocked), on a super-lean config draws only 670W (730W at the wall), so a 700W PSU would be sufficient.
If you overclock, prefer at least a 900W PSU.

Personally I run 3 cards with downclocked memory on a 1200W PSU (1110W at the wall).

Windows or Linux?

I am not sure 3 dual GPU cards can run on Windows.  My problem is the mobos I have do not like BAMT.

I have 950w PC Power and Cooling PSUs.  Should handle those good.

I have put in an order with my other loan shark.  He usually does not get back to me for 24 hours.  I will let you know if he says yes!!!

I am NOT asking you to hold anything for me, so sell away if anyone wants to buy. :)

Thanks.

I am not sure 3 dual GPU cards can run on Windows. 

you can run up to 8 GPU cores, so 4 dual cards.

Really??  I always had trouble with more than 5 GPUs.  Could never get three 5970s working together.

Try harder ;D

I'll admit more than 2 5970s is a pain in the ass in win7 but it is possible, 3 5970s in Linux is much easier, 4 5970s in either and you'll pull you hair out for a week but it's very satisfying when accomplished.

The 8 gpu cores is a driver limit put in place by AMD.  Some people have had limited success in linux using virtualization to bypass, but yes, it is possible.

I am really interested in these still!!!  I have wanted some 6990s SO bad lol

Would you be interested in trading for 7970s?  Is there some deal we can work out where I get three 6990 and you get two 7970 of mine and something else?  Maybe some BTC or Dwolla?

I got mine brand new about 2 weeks ago.  Asus 7970.

Sorry, no trading. I don't have time to resell the 7970s. I could sell you a smaller batch maybe? 5 6990s for 365 BTC.

12.x drivers will not work in Windows with more than 4 cards/GPU Cores.

I use 11.12 for my 5-card and 6-card rigs in Win7 x64 with no problems.

I really do want some 6990s ... I have made good progress with my loan shark.  Maybe he will do a smaller loan to get 5.

I will ask him.
