HELP!!! Question about drivers dll files and nicehash

[BLuE_COiN]

Hello .

I 'm trying 11 hours now to find a solution but i can't.Jesus!
Ok.I have one graphic amd 7950 and i bought a rx 580 and i add it on my pc and now i have 2 GPUs on one PC.
I am mining with the nicehash(NiceHashMiner_v1.7.5.13)
And i have the latest amd drivers but the problem is that the  amd 7950 gpu has only 50000 H/S with the newest amd driver but if i uninstall and install 15.12 amd driver the hash speed goes back to normally(278000 H/S)
And because i can't go back to previous drivers because i run on my system also the GPU rx580 so i read some guy on an other forum said that:

"The easiest downgrade amd driver
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"

And i want to ask you ,do you in which folder exactly sould i paste this 6 dll files if use nicehash(NiceHashMiner_v1.7.5.13)?

Hello ,anyone?

Do DDU in Safe mode and give latest relive beta drivers a test, make sure RX 580 is the primary GPU connected to x16 slot, display cable plugged in and check the results.

I already did the DDU in safe mode ,also RX 580 is the primary GPU connected to x16 slot, display cable plugged and the result are the same.
I need HD 7950 to have her own 15.12 drivers and the rx 580 her own 17.7.1 drivers also.
How can i do that?

I don't know how you can achieve a multi-driver system for the same architecture but I would recommend you to give Linux a try and see if it works.
