Seven different entries are in stock, which is a record, and six are accepting preorders.

This is better than the best times for the RX 470 (which currently only has four entries in stock).

Alas, none are reference cards. I'm never going to get a 2nd one am I? Maybe I should just finish the games I'm playing, join ps now and play some of those games on my integrated video or my old video card while I wait for rma. That would give me time to wire a new 4pin molex, and 6 pin that are shorter out of 16 awg and use a powered pci express extension cable to take some stress off of my motherboard. 8 inch runs on both should give me plenty of head room.

Otherwise if I'm still waiting when Vega comes out and prices are still what they are, maybe I'll sell mine with the block and get vega if it's reasonable to do so. Between the block and the card I have 320 into it. People are selling their used 480s without a block for 275 right now. At today's prices i'd make money off the deal. I'd buy vega, get rma on the 480 and then sell in that order. We'll see in October if I can't find a reference card by then.

On the black screens, one other user was having that and was trying to raise the idle voltage to fix it. I don't think that worked. I know I run higher voltage on my lower p-states than most and haven't had the issue, but I"m on a 480. The user was getting it once every few hours in firefox. I don't know, he might have RMA'd the card to fix it. Multiple people recommended that to the user. I can't find the posts right now it was a while ago. I haven't had the issue. One black screen once at failed oc and one red screen once at failed oc. Both were on launch drivers.

RX 480 has the shortest payback period of all GPUs - 164 days (assuming $199 purchase price). The best nVidia card is the GTX970, with a payback period of 311 days (assuming $259 purchase price).

GTX 1060 only has a hash rate of 20.
I'm quite sure Fury does more since 290s do like 29MH/s no?
Performance/power wise the NV cards are on par now as long as miner is not lazy to use Linux. Obviously buying prices differ but then reference 4xx series is so hiked might just as well buy 1070s for mining really, 32MH/s @ 150W.

Of course the 480/70s are most attractive to the electricity wasters.

My numbers are from here, I don't do any mining - taking six+ months to break even doesn't even take into account additional cooling costs or the impact on comfort (of course, if you have a rig setup with ten RX 480s, and you have them setup in a vented closet or somewhere vented outside, and you have cheap electricity, you can make $2500 in a year... maybe).

My Nano does 26.5 MH/s at 940 MHz core clock. A Fury X easily should hit 30 MH/s.

For ETH mining...

290s/390s/xs seem to be the best still. People are pushing 32~ mh/s on average. By the best, I simply mean the fastest, but they are nowhere near the most efficient. You only want these if your electricity is free or extremely cheap.

FuryX will do 29.5mh/s at stock clocks. I drop the power limit down to -50% and undervolt as far as possible (usually -66mv in Afterburner, but many get -100mv) and it does 28 -28.5 while saving a ton on power. That is my main PC though (gaming rig), so I don't really mine with it. Just test things periodically.

My mining rig is 4x 480s and 2x 380s (and swapping a 380 for 1 more 480 tomorrow). 150mh/s (soon to be 158ish) using 835 watts measured at the wall.

480s do 27mh/s with core underclocked to 1050mhz and undervolted, Vram overclocked to 2200. You can get 28 at stock core and VRAM overclocked to 2200-2250. Also, there are now people testing custom bioses that do 30-31mh/s. Once again though, efficiency is important to me, so I'm sticking with 27mh/s while using less power.

If anyone really gets into this stuff and has questions, feel free to ask or PM me. I've done a lot of reading and testing over the past few months...

Eh... now I'll keep the 480 for sure. If I can keep the memory overclocked... ofc. I only get 25 MH/s at stock. 28 MH/s with 2250 MHz memory, but it's unstable at stock voltage.

There was a reference card available for 266 today on B&H. I couldn't decide in time and it's gone now. The whole not letting Hispanic employees use effectively "white's only" bathrooms and keeping employees in the warehouse to work as it was on fire thing had me questioning my patronage. I've shopped there before. My Grandfather, now deceased, shopped there years ago and purchased a super 8 camera and projector from them. I purchased professional video equipment from them. Just took me too long to decide that I wasn't the arbiter of how they treat their now unionized employees. Card's out of stock now anyway. Anyone pick one up?

I have to recommend the MSI Radeon RX 480 Gaming X 8 GB. It's a great card for Ethereum (ETH) mining.

My favorite bench at the moment is Ethereum (ETH) or Ethereum Classic (ETC) mining.

At stock speeds in OC mode (1316 MHz core/8100 MHz memory), I get 25 MH/s spot on. Temps are at 50C with an adjusted fan profile, a temp target of 70C. Case in point, this GPU is frosty when cooled right.

Yeah except that MSI versions sell for 319+ EUR frown.gif
It seems to be the best cooled one but also the most expensive one to the point one might as well buy a 1070 for 399 EUR.
Locally the MSI Gaming prices are insane and not stock either. Way too popular in recent years which skyrocketed their prices from MSI and from demand.

Trying for maximum hashrate at this point. 1370 MHz at 1150 mV, see if that's stable, and 2250 MHz at 1025 mV, see if that's stable too. Getting 27.8 MH/sec at this speed, 2.9 MH/sec more than at 1316 MHz at 1100 mV and 2000 MHz at 975 mV.
