newegg has these back down to $220-20mir, they were $240-20mir yesturday
anyone manage to use MSI Afterburner or TrixX to UNDERClock this card so it consumes less than 185 watts? i read some mining forums that do it with this card in unix, but i had hoped some Win7 utility might as well.
i just bought the card today, so it should be here by Monday. i hope i get a good one... i also read on mining forums (where they put 4 of these in the same rig) that OC stability can vary a bit from card to card.
does anyone know if the HDMI or Displayport is 2160p capable? all the tech faqs i read keep saying this card can only display up to 1600p on a single panel, and that only the more expensive Vapor-X does 2160p.
Card came Friday - using Catalyst 13.4 (May29) - could only get a stable 10% OC of 1018/1375/1.11v. TriXX messed up RAM, so I used MSI-AB instead. Heaven&Valley on High 1200p averages 940 37FPS, while Temp/Kill-A-Watt/Fans remains under 60c/300w/2000rpm(quiet). FYI my CPU/RAM/NB is also OC by 10%, but even with no OC on the mobo, the GPU could not be pushed higher without becoming unstable during Heaven&Valley.
I spent more time OC and found I could get the card stable at a 20% OC above boost using TriXX with gpu/mem/vddc 1110/1500/1200 but I would see graphic artifacts between programs and games and Temp/Kill-A-Watt/Fans at 70c/400w/2500rpm, so I settled on this 15% above boost with 1064/1438/1168 odd number and below what others can get, but at least all my programs seem to behave and my power/heat profile is more appropriate to the rest of my build. I suspect I need a better PSU or perhaps more mobo tweaks - I just hope I didn't get a lame card. I read some of the miners who buy 2-4 cards at a time say some individual cards OC better than others. Heaven/Valley on High at 1200p shows 37/47fps.Edited by spypet - 9/14/13 at 2:13pm
