If I'm posting in the wrong place I apologize. Move it to where it needs to be or I can.
Anyway, in Michigan but can ship, selling 4x 290x's (sapphire tri-oc's)
660$ each, or 640 if all 4 are purchased together (if you're close and shipping costs are lower, the overall price will be lowered with it). We have sap 290's as well but we're still deciding if we just want to keep them or not ( 2 @ 930k/khash stable, 1 @ 880). We actually have more than these, but we're only parting with a few for now depending on how things progress.
Info:
~3 weeks old
Have receipt, standard warranty (2-year for Sap), there have been absolutely no violations to sapphire warranty *(removal of HS, firmware swaps, etc). They are very strict about any hardware modifications to my knowledge.
Original everything (box, cables... hdmi cable and pci express adapter, static bag, etc).
"Mint" or I guess "Excellent" condition, but they HAVE been opened and used for ~ 3 weeks for burn-in/testing.
History: We build and host gpu miners for people, had an investor pull out last minute after testing his requested hardware. We decided to refund his deposit and keep the hardware. Thought about it later and instead of exchanging we're just going to sell as 290x's require a bit more hardware than we need for our standard builds (just being honest, the cards require a lot of juice, min 1200w psu for 3 on OC's. Our rack mounts don't have the size to fit the size PSU and they are kind of the black sheep of our current gpu builds). I'll probably miss them, but they have been a PITA with my current remote management. I know, I'm not the best seller on earth.
Can confirm the following:
1) Temps under 80c at peak load OC'd @ 70% fan (it's a sap tri-oc, they don't overheat... like at all. 70% fan is just what I set everything at). These temps are without any air flow, just open rig. Under outside fan control you're looking at closer to 60c.
2) All 4 290x's OC just fine, have long term stability screen shots at 1008-1010 k/hash on cgminer on a gigabyte board. On our Asrock's we run them closer to 960 each stable 100% uptime @5 days. In other words, it's not one of the memory sets that crap on themselves the second you push them past stock. I run them lower because I use teamviewer and it tends to make cgminer go b-sh... crazy if I don't keep the clocks down. Obviously can't guarantee your setup will yield perfect results, but just wanted to give you an idea of expectations. Benchmarks have been done on Windows 8.1 (the 1m+) and BAMT (950-960). Admittedly I haven't spent as much time pushing them in BAMT. Once they're up, stable as a rock though, no HW errors.
3) Cool with paypal, BTC (escrow's fine if needed), etc etc etc. This isn't some scam and I can show my personal company information, location, address, yadda yadda for serious buyers. Regardless, we'll meet whatever requirements that are necessary to make you feel at ease on you purchase.
PM for further info/inquiries.
I don't respond to trolls that feel obligated to put their two cents in to every post here to + their post count, look elsewhere <3.
Thanks,
J
