RX 580 almost no overclock

[Cris.py]

I recently got a Saphire pulse RX 580 4gb and decided to see how much overhead I have. It should be a decent card - not necessarily great, but decent. I got power limit to +30%, but I couldn't get a stable OC over 20 Mhz. When I went from 1366 to 1400 it crashed almost immediately, with temps going no higher than 72 C. Is this expected or am I just very unlucky with silicone lottery?

Yes, RX580 is already push to the max by AMD from it's original RX480 design.

This and the card is factory overclocked already. Chips that clock up to 1400+ MHz probably got sold as Nitro+ cards.

I've seen people go as far as 1500 MHz on some samples and "normal" OC was around 1450 ish so I assumed 1400 MHz should not be a problem. Seems I was wrong.

Tried my one at 1450/2125 I think, with max power limit = crash. Anything below these values makes no bigger difference on fps (maybe 5fps more)  so I went back for stock 1413/2000. I think its not worth to do any OC on that card.

Your GPU may already be overclocked from the factory, leaving little overhead. I know my old Gigabyte RX 570 was and it became unstable with only like a 50 mhz overclock...Sometimes you get lucky, other times you don't. I've had CPU's and GPU's that I was able to overclock and others that throw a fit. My OC'd Ryzen 5 1600 af doesn't seem to play nice with the memory running at stock speeds. I had to underclock my ram from 3200mhz to 2800.

 

Have you tried overclocking only the vram? Sometimes it will yield very good results.
