RX Vega 56 crashes at stock speeds (Furmark) and runs worse in games when OC'd

[av28]

I got my vega 56 just yesterday second hand, and I was curious about OC-ing it, I ran my OC while playing Battlefield V, and the frames were noticebly lower than what they were when the graphics card was running at stock speeds. I decide to run furmark and it black screened with furmark crashing so I set it back to stock. I try furmark again and the same black screen fur mark crash had occurred. Did i buy a faulty vega 56? Throughout the years of owning many GPUs I have never seen one crash at stock speeds.

 

I have not done any undervolting, and of course I have set it back to stock. However, it can play games just fine; no freezes or crashes.

It's probably just unstable with your overclock or the temp/power was simply too high.

for sure don't try to furmark a Vega 56 card lol reference PCB is fine, some others may not handle it well.

So it's normal for it to crash on stock speeds?

In furmark maybe, it runs games fine with stock speeds right?

Yeah, it works 100% in games, no problems what so ever

Never mind my previous reply, it black screened while I was playing Forza Horizon 4. Im going to claim to the seller that it is indeed faulty.

I think I fixed the problem, I set the Power Limit to +50% which seems to have fixed my problem

According to the internet that's usually the way to fix it, however actually reducing power by 10% seems to have worked for me, i wonder if i could just clock it more similarly to an RX580 in order to make it completely stable.

Ah ok, I was afraid it was faulty haha. The vega 56 had me unexpected as to how unstable it is
