Hate to ask but has anyone had any experience with their Vega tripping the OCP on their PSU? During certain scenes (mainly Destiny 2 loading screen) my PC will make a loud click and cut off. Power and reset buttons are unresponsive and I have to turn the PSU off for a few seconds before I can boot it back up.

At least I think that's what it is, maybe my PSU is just going bad.
Yes actually I experienced that when testing my Vega 56. I run a 450W PSU and the stock turbo settings were tripping OCP and shutting the system down. After undervolting and power limit tuning to get the core in the ~180W range it never did it again.

I've got a Vega 56 flashed to 64 and registry mod for 100% power limit but it's undervolted to 1050mv. I thought my PSU would be okay (850W FSP Hydro Gold) but maybe it's too much. I'll dial the power limit back to normal levels and see if it happens again.

Wow, you're living on the edge there, hard to believe it even works. I've never seen any OCP problems with my V64 and man, I've had that thing running so hot I could smell it, burnt my finger on the back of the card.

Vega can be decently efficient if you aren't throwing all the limits out the window and expecting to push it right up against the max turbo. My whole system drew just shy of 400W from the wall with the Vega 56 hovering in the 1480MHz range, with spikes to 1535MHz. Good enough for me.

I can easily push mine over 350W if I run 50% power limit so yeah it can easily eat up an underpowered PSU.

Which is what I was doing. Undervolting then maxing it out. I haven't messed with it in a while but I'm pretty sure I was well over 1600

Correct, it can do that. And, as I have experienced, it can also not do that. Strangely enough with most of the tuning options left to the user, multiple people can run the same card and get different experiences with that card.

Sure of course, can easily go the other way and under volt and still get great clocks. He flashed his 56 to 64 for higher power limits so he’s going high not low. I’ve settled on 35% power limit and hit 310-315W and 1700 peak boost, average 1650-1685.

Truth be told I haven't noticed much difference between 50% and 100% (besides my system cutting off lol). My Vega pretty much holds in the mid 1600s all the time with 1100mhz on the HBM.

The idea of using the registry mod for crazy power limits sounds cool but not cool enough for a new PSU

Oh you're still talking in relation to @Partaypooper's issues. I was just responding to the reaction of disbelief that the card could run on a 450W PSU. Yes, when you throw the limits out the window to reach peak performance you will absolutely see that exponential increase in power draw.

I’ve settled on 35% power limit and hit 310-315W and 1700 peak boost, average 1650-1685.
If I had a 550W I would have likely tried to push for that. I think 1500MHz is the sweet spot for Vega 56 at 1.06v - 1.09v. That seems to be a decent balance point where you can push the power limit all the way up and get that 10% performance increase without actually increasing power draw from the wall.

And why undervolting is the best way to overclock Vega. From my experience, I don't see any need at all to up power limits.

Just a small update, I think it is my PSU. Even with 0% power limit and undervolting I still get hard shutdowns during specific scenes in games. I enabled FRTC for 143fps and Radeon Chill and that seems to have fixed my issue. PSU is an FSP 850w Hyrdro G

I already had the frame cap enabled in Destiny 2 but turned it off when using FRTC. Since making these changes I've played a good few hours with no shutdowns, even with 50% power limit.

My Vega56 is through very low voltage diet. I really loved that Vega became very efficient at lower voltage (and lower frequency at ~1500MHz), its quiet, the heat is manageable by stock blower cooler adn don't produce much noise either. This is on stock Vega56 VBIOS with overclocked HBM2 to V64 speeds.

Without googling, is "OverdriveNTool" something new? Never seen it before.

Go to for proper “fine tuning” I’m just lazy and use Wattman but been tempted to use it and copy good profiles like his.

No, its been out for quite a while. Its designed for mining at first if I'm not mistaken. They released a new one to utilize new features from new drivers like Vega memory timing level and the 'ladder-step' fan control. What I like about this software is it can tune all states and not just P6 and P7 so it can truly undervolt the card at lower 3D states by tweaking PowerPlay table and save it to registry. If you heard about power limit registry hack, you can do it here as well. You can see my power target is at 100% because I raised it from stock 50%

Do you want the powerplay registry files? Here's the files, I made two, one with stock 800MHz HBM2 and second is 945MHz. Both have stock 1590MHz max core clock and 100% power limit. From my testing the clockspeed will hover around 147xMHz at most (tested with Shadow of Tomb Raider), good if you wanted low power and low heat. Just double click the registry and either restart or log off and log in back.

Thanks I need to tear down and flush my water loop before I can mess with that but yeah it’s a good way for me to dip my toe into Ntool

I've done some more tinkering. Looks like OverdriveNTool can set minimum and maximum clock like Wattman do. Just double click on the pstates and when its greyed it won't be selected like pictured below. I noticed something interesting, the row of LED on reference Vega cards next to PCIe power plug corresponds on which pstates it was on, when I selected like pictured below 8 LED's were on (if only p0 is selected one LED, p1 only two LED's and so on).

The reason I try to do this is to 'force' the card runs at higher clock but at lower voltage, but alas the card intelligent enough to know what's the clockspeed it stable at. Even if I selected 1630MHz at 935mV, in Shadow of Tomb Raider the clockspeeds hovers slightly above 1500MHz, mostly around 151xMHz and peaks at 1580MHz. It runs stable and didn't crash. interesting find.

Any Vega counts , the title was vague to allow it :)

welcome to the club but more details would be nice like, whats it in ,whats it called and possibly do a 3dMark(free Ver or paid) time spy stock bench as it would be nice to see what a more unusual (to the club) can do.
