Hi all,

I started mining with Claymore a few days ago and I am seeing an upsetting thing.
My GPU is an EVGA GTX 1080 FTW, watercooled, MSI Afterburner reports a RAM frequency of 5000 MHz, which is fine... but when mining with Claymore, the RAM frequency automatically drops to 4500 MHz. If I stop mining and start a game, the frequency goes back to 5000 - the 4500 MHz behavior only appears when mining using Claymore.

I suspect the driver somehow knows I am using Claymore and taxes me for that.
If I boost RAM frequency by +1000, it goes up from 4500 to 5500 MHz and the hash speed goes from 20.5 MH to over 25 MH - 25% boost - but this solution is clumsy, because whenever I stop mining I have to dial back the frequency boost, otherwise as soon as the GPU encounters any regular load, it tries to boost from 5000 to 6000 MHz and the memory can't handle it.

What should I do to keep mining with Claymore, but at correct RAM frequencies?

Anyone?
Is the driver detecting Claymore and forcefully reducing memory speed?
Is there a workaround?

I Got a similar problem with 1 of my RX470 rigs.
Try this and it might work:
Default the GPU via afterburner.
and then restart. Default it again. Remover after burner and any trace of it from your system. Restart. remove the driver via display driver remover in safe mode( run it, and it will recommend and offer reboot to safe mode itself). Install the latest driver. Install Afterburner. And see if the problem goes away.
I did something along these lines and my problem was fixed. I had 6 GPU locking on some ridiculous settings while the 7th being Okay, resulting in system crash minutes in under the Claymore.

The settings go in drivers and even registry some times...
