The RX Vega 64 Owners Thread

Hey guys, do any of you have this problem? I just worked out when/how this is happening, but am stumped as to what the solution is.

TLDR - When you set Voltage values from Wattman, (1.15-1.2V), it only uses upto 1.15V in-games.
When you set Voltage setting to "Auto" in Wattman, it uses 1.18-1.2V like in Matt's videos.
It is the same behavior even if I set both p6 and p7 to 1712 MHz @ 1.2V, (it would still not go beyond 1.14-15V)

What is going on here, and the latest driver hasn't helped. This kind of makes sense why my card was crashing all this while instantly because it would try to run 1700 MHz on 1.14V. I can upload a video if that helps, but the issue is quite self-explanatory.

Using OverdriveNTool hasn't helped either, it's the same. No-one here has faced this problem with their Vegas?

EDIT - Just tried adding +37mV from MSI Afterburner and it bumped it from 1.150V to 1.186V, so this appears to work, I could still use help with the problem.

EDIT 2 - Can Afterburner appear to be the issue? RX Vega LC has upto 1.25V capacity, I'm locked exactly 100mV below that which I can change w/ Afterburner. I didn't try un-installing AB and checking because.... OSD.

This really needs to be looked at.

It happens, what I did was, the first time I selected my Cache Segment and "Applied", nothing happened, Radeon Settings just closed.

All you have to do is re-open it and set your cache again, this time it should work.

Also restart your PC after doing it because for some reason it will start corrupting your Radeon Settings window if you go and resize it, after the HBCC setting application.

From what I understand, it starts from around 11.5GB , since there's no clear definition of what it's doing, all I can say is it feels like it just adds the amount from your system ram.

i.e set 13GB as Segment, you will add 5GB of System Ram to your 8GB of HBCC to make it 13GB VRAM.
