Someone with stopped rigs around 04:00 (+2 timezone)? All of my rigs stopped!

Go mine on Dwarfpool!!! No stealing shares  like other pools..... I switched from flypool to dwarfpool, and I have 15% more shares!!!(my real shares)

starnge ...
I chenged driver, changed riser ...
but still my 390x does blow 270, my giga 390 with 1020  clock hashes same exactly while 390x overclocked to 1090,
gpu 0 is 390x also it is not connected to display
any help

Close things like afterburner, gpu-z, trixx, mining, etc. Use atiwinflash (latest version), save bios from card (preferably a card with dual bios switch in case of a bad attempt...).  Open with polarisbioseditor, copy straps, save bios (diff file, so you can revert to original if you need).  Then load modded bios with atiwinflash, and restart. There is a youtube video on how to do it (search for it).  Best to do at the computer (not teamviewer or vnc).  It often freezes after flash (shows success message, then computer is frozen, or ridiculously unresponsive.  If this does happen, it shouldn't be an issue, just annoying.  Then test for stability, I have never had issue using 1500->1750 or 1750->2000.

I copy 1750 to 2000 on 2000Mhz (8gbps) cards, and 1500 to 1750 on 1750 mhz cards (7gbps).  You can see what works.  Newer miner versions the tighter timings have less affect, but helps Ethereum mining immensely (~12% for free, using 1 strap lower).  I have flashed about 20 470/480s (all sapphire nitro, some 4gb, some 8gb).  Only messed up one bios (before I figured out my next tip...)

VERY IMPORTANT, use driver version 16.9.x or later, versions before this checked bios signature, and Win7 will fail to see card properly, even on a successful flash, device manager sees it, but says something went wrong.  It doesn't hurt anything, it just won't work until you get newer driver, or flash to stock.

Asrock 81h BTC pro around 70 euro from Amazon
Asrock 97h Anniversary 80 euro

Both work perfect with x6 GPU's

and its not as simple as just taking 2 furys and doubling the hash rate because you have to double the compute units and double the memory meaning in theory a pro duo is 3 times that of a fury

Pro duo has 8gb hbm memory if a 295x2 can do 560 s/s at 88 compute units then its very easy for a pro duo to hit 1000 s/s as it has 128 compute units and faster memory access if you look at the fury pro thats coming out next year that uses hbm2 memory at 64 compute units which will sit inbetween the 295x2 and the pro duo the pro duo also has advanced power effeciency technology to allow it to only run at 300 watts thats the whole point of hbm memory

You can wait forever...

 Still waiting on a LINUX version, since Windows is an active PAIN to deal with if you don't have 100% reliable power.

 It's accurate - but INCOMPLETE.

 That's the power the GPU chip ITSELF is eating - does not include the memory chips, the interface chips, conversion efficiency loss, etc.

 Doubt it, the memory on those isn't all THAT fast - they should be comparable to a little faster than the Nano/FuryX.

I've read a lot of people have flashed their RX 480s with the 1500 timings to increase Sols/s. I have the 8GB Ref versions. Would this work on my cards, and if so, could someone point me in the direction of a tutorial? Thanks!

it's very impressive information. I like this card

 280x is 384 bit memory bus, RX 470 is 256.

Same way as you, that it is....

Thanx!

16.10.1

For RX 480 what version of the driver is recommended?

yeah it can do 4 cards but no more than that

it ain't..? How would you know?
