As a matter of fact there's no need for a third party app. I've added a DWORD in registry for the cards and hashrates in CastXMR have gone up by over 10%. I am assuming this would solve the problems I was having with Claymore. I'll test it later when I get some time.
Oh yeah, that also should do it.
Posting it here for sharing
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
"KMD_EnableInternalLargePage"=dword:00000002
Keep us posted if it solved your issue bro
