Yeah, I got mine on Thursday I believe. I just have it tucked in a system now for some basic testing, but the thing hashes remarkably well at low clocks. I'm probably going to try the 4GB BIOS since it allows lower memory clocks, but I'm getting 23.2MH/s at 900MHz (850mV) and 2GHz mem clock. No power measurements until tomorrow probably, but it must be sipping power; it's running at 1450RPM and 68C in a case with that load.
Strange, when I tried to download the claymore miner from nanopool chrome blocked it as malicious.
Is claymore really that much better than ethminer?
Test a bit more, decided to just stick an old monitor on the ref 480.
Question: when running Claymore on the 480, are you using any files from older driver revisions, or are you using the new 16.7.1 straight-up?

I don't get this. Driver versions never made any difference for me. 15.12/15.7, 16.5.2, 16.6.2, Windows 7 64-bit.
That applies for both my 280X and 290X. Are you guys going by ethminer/claymore reported hashrates, or actual hash rates based on pool or revenue from solo mining?

So now that the 480's have been out a week or so what's everyone's mining impression of it so far?

I took one look at decred's difficulty curve and value, matched that up against the extra heat caused from mining it via Claymore, and said "blech".
I've decided to lay off the DCR for now, but for reference my temps were:
Eth-only (GPU/VRM1/VRM2): 58/65/64 -100mv and 0 Aux voltage
Eth+DCR: 62/79/66
Rock solid. I should have purchased more.
Solid little cards. Better reference cards for mining than the 290s. When they are easy to get they will completely screw up the difficulty curve.
I still am not able to lower core/memory clocks below stock frequencies.
Undervolted to 900mv and underclocked to 1ghz. memory @ 2000mhz. Core pulling 80w and fan speed only 36% and quiet to keep the card at 79C. Can't even hear it over my test bench fan. Much easier to deal with then the 290 reference cards. Getting 25MH out of it at those settings. I was able to snag a 4Gb on launch day so Im pretty happy with the results.
Agreed - where I had to fuss with my 390s these just chug along. Undervolted they perform well and stay nice and cool.
The 80w you cite, is that with GPU-Z?
I'm still trying get get an accurate picture of total power consumption (including board) for a 480 mining at 25Mh.
My 4GB 480 flashed to 8GB gets about 24.7 in Claymore. I need to find a guide on Wattman or something. Everything I do in there hurts my hashrate.
