I have been trying to get some coil whine under control. I have a Vega 64 Nitro+ (non LE) and whenever I scroll or even hover over tabs in a web browser for example, I hear a buzzing sound. It's been slowly driving me crazy over the last few months. I've spent 5+ hours trying to figure out the issue over the past couple days but haven't gotten anywhere.
I first tried just using the kext file generated by VGTab but as this guide explains, that was likely not working due to also using WhateverGreen. I've since followed this guide for patching my config.plist file several times, but again to no avail.
I only really care to underclock or undervolt to try to prevent the coil whine I'm experiencing. The fans are pretty much silent and keep the temp around 30C or lower.
No matter what settings I use in VGTab, iStat menus always reports low core clock speeds, generally less than 200 MHz, and the memory clock seems to always be set at 500 MHz.
Here's what I have in terms of config:
I have updated WhateverGreen and the other kexts from pastrychef's golden build guide's most recent EFI directory.
Any help on this would be greatly appreciated!
