Got my new MSI R290 (non-x) card from Newegg today. Ran a few benchmarks in Windows. It's very fast and fans aren't loud unless you overclock/powertune it.
Of course, the big question I had was: How well does it mine?
So here's my setup:
- Intel 3570k CPU on a Z77 mobo
- 16GB of 2133 RAM
- Windows 8.1 x64
- AMD Catalyst 13.11 Beta9.2 driver (came out today)
- cgminer 3.7.2
thread concurrency 32765
The card is in a well ventilated case and fan speed was set at 65%
The hashrate stabilized around 843 kh/s. I suspect there is room for optimization (e.g. shouldn't the 512-bit bus be good for scrypt?). I was hoping for a bit more performance/$, but maybe that will come with time.
I won't have time to try other settings or measure power use until the weekend. If anyone else has a card, post your results here.
