Tried installing the blockchain driver on a FRESH Win7 install yesterday.
Per it's release notes, it SPECIFICALLY states it supports the R9 290 (I had 2 of those in the machine) and it looked like it was supposed to support the "R7 graphics" in the A10-7860k in that machine.
Actual results - it installed, but flat out did not recognise the A10 iGPU at all (came up as "standard VGA adapter" in device manager) and would not install on that no matter what I did.
It SUPPOSEDLY installed on the R9 cards, but NO OPENCL SUPPORT both per GPU-Z and from trying to run openCL software like the DNet client, Claymore ZEC miner, and both Genoil and QTMiner for ETH - no matter what I tried, it flat out WOULD NOT INSTALL OpenCL.
Without OpenCL support, there is ZERO POINT TO THIS BROKEN DRIVER VERSION.
Makes me wonder, YET AGAIN, if AMD bothers TESTING their crap RElive bloatware on all of the cards and OS they CLAIM the stuff is supposed to work on.
Machine is now happily working Moowrapper/BOINC/Dnet via LINUX (took me about an hour to "clone" a pre-built USB key installation over to that machine's HD - most of that waiting on DD to copy the installation over - thank goodness for 15.12 drivers!).
AMD drivers have been such a total load of bloatware garbage often BROKEN nightmare since 15.12 (though some of the 16.x versions were tolerable) that I'm about to the point of just saying "forget AMD, I'm going all NVidia" for GPUs and I've been looking seriously into alternatives for my current "go-to" AM3+ based platform.
I've ALREADY decided to completely ignore Vega (the pricing BS coupled with the low performance and INefficiency had me thinking "don't bother" already) and the RX 5xx series (after ONE MORE TIME around the "Relive is bloatware garbage" block, I refuse to even bother LOOKING at another Relive driver version ever again).
Don't even get me STARTED on AMDGPU-PRO on the LINUX side - they're STILL trying to play catchup on support of even the R9 series, the available tools are an even bigger joke than ATICONFIG, no support AT ALL for Tahiti after 2 bloody YEARS but they can support low-end junk like the R7 250?
NVidia LINUX support was a tossup for AMD even back in the fglrx days - since the move to AMDGPU it's been no competition at all.
They don't seem to realise how much their "penny wise, pound foolish" short-sighted "don't care about LINUX, don't worry about putting competant work into drivers" attitude is poisoning the well among us long-time AMD fans.
If AMD doesn't get their act together on GPUs, they might just find themselves in the position of being PERMANENTLY locked into trying to compete only in the "value" segment - and if it wasn't for cryptocoin mining, they'd be losing out even THERE at this point.
