tks for the answer..

Where can i find this driver?

(on AMD site i cannot find)

Simple google search would give you this. But anyway, you are probably downloading it because of claymore and I can say that I always used newest drivers and never had any problems or major performance loss

use this to uninstall any video card drivers AMD or NV , it works better then some of the paid version at it's level and i would uninstall them in safe mode .

direct download link from AMD's site for the Catalyst (Crimson) 15.12

http://support.amd.com/en-us/download/desktop/previous/detail?os=Windows%2010%20-%2064&rev=15.12


Like  eckmar  say use the newest drivers and I 'll take it another step that's bad advice claymore gives on what drivers to use because some cards are not supported by the Catalyst (Crimson) 15.12 and those drivers can be the main problem in some cases and tomorrow if what I read is right there is a new drivers releases coming form AMD that will be awesome . but well see tomorrow .

And drivers do matter in how they run the cards they power and the software those cards run .

yes that is the reason, and i already tryed this link..

Not working for W10 64bits..

if the newest is ok, i will continue to use.. But the hash at my R9 390 (i have 80 GPUS) is not equal to the stock that he mencioned on the ZCASH 9.0

do a clean install of the drivers turn off any thing that may use those driver or card before you uninstall them like antivirus software, any profile software you may be using like after burner , awesome miner etc and you may even need to reset you cards default to default with software like after burner and make sure some stuff is off or on for that  card with afterburner, you can't see other wise that keep turning on or off  or some profiles not Turin off on there own or not deleting, or Windows installs it own profile after a driver uninstall or the driver gets stuck on a profile no mater what you do.

tks!!

is it better to get the old drivers?

Horror, tomorrow will need 16.9.2 and all over again))) upgrade downgrade
The easiest
We take the dll files from 15.12, or other
amd_opencl32 amd_opencl64 amdocl amdocl12cl amdocl12cl64 amdocl64
Put in folder miners
That's the whole downgrade

To remove any amd or nvidia drivers you could check out this program. its called Display Driver Uninstaller.

I try to link direct to the DEV site if i can that way no redirecting and you get it form a trusted site you know you can trust .

If you're running the older cards, R9 3xx and before, or the Fury/FuryX/Nano, the 15.12 drivers seem to work well more consistantly.
If you're running the WX 4xx series cards I'm pretty sure you have to run some of the 16.x series drivers.

Hopefully nobody mad I am resurrecting an old thread.

I am running an MSI RX 470 8GB OC. I switched to Claymore Dual today from Genoil Miner so I could mine two coins at once. My driver is 16.300.2311.0. I have notice a hit in mining Ethereum by about 2 to 3 MH/s but I am now mining Pascal coin also (I tried Decred but every pool rejected all my shares so I switched to Pascal and all shares are being accepted). As mentioned above Claymore recommends downgrading the driver to Catalyst 15.12. Will I see a little more speed in mining Ethereum (I am minin on ethermine.org) or should I leave the latest driver in place. Before switch to Claymore Dual on Genoil I was leveraging 22 to 23 MH/s (varied a lot with some quiet high spikes and some very low lows) now on Claymore Dual I am getting a pretty constant 20.5 MH/s.

 If you are mining on a card that is older than the RX 4xx series, the 15.12 drivers seem to still be the best combination of best hashrate (though some of the 16.x drivers can argue that point), ability to use modded BIOS (lost as of about 16.11 and never came back), and stability.

 For the RX series, you HAVE to go to a newer driver - IME the 16.9.2 WHQL driver is the best for those cards for mining, but any of the 16.9.x and 16.10.x seem to work reasonably well.


 When using the dual miner, you WILL lose a little hashrate on ETH while mining 2 coins - you're SPLITTING the GPU between the coins after all.
 The concept is "small loss of ETH for large gain on the other coin that more than makes up the ETH income loss" not "no loss of ETH income and added income from other coin" due to differences in the parts of the card each coin uses heavily.

If you don't know how to downgrade AMD drivers you really shouldn't be mining in my opinion....

[dmatthewstewart]

Im curious if anyone knows about using the 15.12 with a sytem run by an AMD apu. I have a board running the A6-7400K and it defaults to 17.1 drivers and that seems to be fine for my 480. I can get it to hobble along at 26mh/s. But I also have a 7970 laying around too. Unfortunately on the 17.1 it only gets about 13-14mh/s. Has anyone run the 15.12 drivers with an APU based system?

If you don't know how to downgrade AMD drivers you really shouldn't be mining in my opinion....

Disagree. Its easy to learn and easy to NOT know if you come from a gaming background and let package managers install updates automatically.

[QuintLeo]

I've got machines with the A10-7860 and A10-7890K running on the 15.12 drivers - one of which has a HD 7850 in it (semi-short card to leave airflow to the middle card in the system, a GTX 1070).

 Anything before the A12 series should work, the A12 probably needs something newer as those were released AFTER the 15.12 drivers were released.
