Dynamic clocks or not, it happens as soon as I set manual voltage control and only in games (Witcher 3 and ROTTR tested).

Will do tomorrow. Why does the HBM drop using dynamic though, it's not directly linked to the core frequency adjustments. My HBM was all over the place also.
Does seem less like a PSU problem.
Heh - you could test the whole system on the 650W to see if that makes any difference. If you're only seeing problems with that one game though, it seems less likely to be a problem with your hardware.

Ok so watched some of your vid Matt, as someone who has never played BF1 before or even looked at benchmarks for it, how does your 123fps average at those settings stack up against other cards? also other CPU's?
No matter what I some (not all) games drop to state 3, 4 or 5 (max) as soon as I enable manual voltage in Wattman.
As soon as I select manual for voltage control and hit apply (even if I don't actually change the voltages) the 3D clocks will alternate between state 3 (1138), state 4 (1200) and state 5 (1401).
- Custom game profile with state 6 set as minimum state - doesn't matter
- Dynamic or manual clocks - doesn't matter
- +50% power limit - doesn't matter
- Max fans - doesn't matter
- Combinations of all of the above.
So far it happens in
- Witcher 3
- Hitman
- ROTTR
- Deus ex Mankind Divided
Works OK for Dishonored.
My Ryzen 1600 @ 3.9 has around the same performance which surprised me. I think that the game could either be better optimized for Ryzen or we have to wait for future revisions with higher ipc.It's around 1080 performance i believe.
As for CPUs I've no idea, i was GPU limited in that video.
Don't touch HBM voltage, as that can trigger a bug which we are working on. Core voltage should work okay though in 17.8.1 WHQL.
Try this. Select Power Save, click Apply. Now select Custom and try the settings below (but whatever your max boost clock is in state 7) and click Apply. Then test some games.
Just leave HBM voltage alone, don't increase nor decrease, just use Core voltage.The voltages in those settings are actually higher than a stock air cooled vega. So are you saying I should increase voltage and set power limit to 50% and also lower VRAM voltage to 950?
Another VEGA 64 LC owner here, came home hoping to play around with undervolting. After playing around with it a bit combined with furmark, people recommended me to use unigine heaven/valley instead.
Sadly enough my system seems to crash on unigine heaven when my card is at stock voltages and frequencies.
650W Corsair PSU, VEGA 64 LC, i7-3770k
I'm running the unigine valley benchmark as we speak, and it hasn't crashed yet. Does anyone else have issues with their systems crashing when running unigine heaven?
Edit:
This is with the newest drivers of course, 17.8.1.

I don't have anything more to add from what i said earlier, so there is no point getting into a debate about it.Thank you, I'll be looking out for a VEGA deal .
There is link to a thread in this post, any chance of giving your time , thanks .

Not sure if you guys have seen this. 0.1mm is quite a difference so careful tightening up those EK water blocks....

You are avoiding the subject , post what you did here over there, let me show you what I do and how the driver is blocking gains from HBM clock increase .
There is plenty of other info I can share how AMD can manipulate driver as they want .
Give me a fair crack of the whip instead of upsetting members here by posting in this thread.
