Hey everyone... happy Black Friday!
Was wondering if someone could provide some insight that is currently (or recently) mining ETH with RX 400 series GPUs. I had my 4 6x 470 rigs mostly on cryptonote for the last few months but am now looking to switch back to ETH+DCR. However, I am still on the 16.10 drivers and know that with those I will only get about 75% of max capacity, so need to update my drivers and possibly other apps.
As far as drivers go, I know AMD published Blockchain drivers that apparently fixed the reduced hashrates but caused other issues with power management etc. I think these are here:
http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-Blockchain-Compute-Release-Notes.aspxbut this says beta version not to be updated. so, is the best driver to use for 470s currently? or is there a better one out there?
Also, I believe that I am at least 1 version behind on Afterburner. I've read that the newer drivers also require newer AB, so if someone could also elaborate on that it would be appreciated.
Finally, is there anything else that I need to be aware of when updating to a more current driver? For instance, will watt-tool still work? I use that for my master under-volting settings and manage over-clocking in AB. Can this still be achieved with the newer drivers?
The "hashrate reduction" is overstated, though real - more like 10-12% in the testing on real mining I've done in the last week for the RX470 (still almost NO change to my R9 290s though) not 25%.
It would appear that the "future DAG testing" method has some serious flaw to it that badly overstated the issue.
The 17.30 blockchain drivers for Windows ONLY work with 10, I've tried to get them to work with 7 on 3 separate occasions now and they just flat out don't work at all even though AMD claims they support 7.
They are buggy as heck as well even under 10.
I think I remember seeing somewhere that the latest "standard" drivers also incorporate the "blockchain" fixes, but some mining software looks specifically for the blockchain version (XMR-Stak and Cast for XMR definitely do).
The LINUX 17.40 blockchain drivers STILL doesn't work with Vega, haven't messed with it for my 470 cards as those are not mining ETH.
To be fair, it seems that NO Linux driver is working correctly to date with the RX Vega - as usual, AMD cares very about getting their LINUX drivers working, and that got a TON worse when they decided to go to the "AMD-GPU PRO" garbage.
Afterburner 4.4 is the most recent version, and DOES work with the blockchain drivers and recent non-blockchain driver versions.
When you do a driver upgrade, always to a clean uninstall/clean install - and you WILL have to "fix" your settings if you use that wattman junk (iffy in Afterburner, if it's not running when you fix the drivers it MIGHT save your setttings, or it might not).
