ok gyus some good news:
crimson-relive-17.10.2-oct23 driver is
1) more stable than the blockchain drv (has the DAG fix that can be enabled with "compute" workload)
2) has proper API (no issues for setting up the volts with overdriven tool)
3) supports more then 8 AMD gpus on the same platform
all good news indeed.

Well, i strongly disagree. My personal experience (and plenty of others) is completely opposite to yours
1) how can you even say that out loud? that driver is not even 7 days old

2) OverdriveNTool has been working just fine with blockchain drv (23aug)
3) yes, it let you post it in device manager and yes, it let you mine with it.. but do try enable compute workload and see that mess if you are running 12 cards! And loosing 4mh's per card with NO-dag-driver * 12 cards.. hell no !
Please stay away from such a comments, you are fooling others!
Actually what Ursul0 cited is pretty factual, as I've experienced it myself.
This driver, together with the Win10 FCU fixed my OpenCL issues - and i've tried everything under the sun to fix it. I used to use aug 23 blockchain driver and a recently-installed win10 pro without any updates.
I only run 8 cards but here's some proof that's it's stable.

Previously with the setup above, miner doesn't get past 3 hours without openCL issues.
It has the dag fix just like the blockchain drivers - and this version is fully-supported by AMD and not in Beta status.
Note that you have to enable *compute* settings in each card in the Radeon Settings for this to work.
