I purchased a used RX 480 8gb reference card from Ebay. I needed a blower card for a small form factor build.
I checked with gpu-z and the core clock is 1266mhz. I checked in wattman also.
I ran heaven benchmark and used the relive overlay. It says 100% gpu usage but the clock stays under 900mhz. I would normally assume that wattman is getting incorrect readings, but the benchmark scores are really poor. Around 1900. I have benchmarked a reference rx 480 4gb before and got a score of 2700. I usually get around 2500 on rx 470s.
I tried to overclock using wattman but that didn't make a difference.
Temperatures are under 70c the whole time and the fan stays around 1500rpm.
With the power slider all the way up to +50% the card can hit 1200mhz. Drawing around 165w According to wattman. Still not the 1266 it's supposed to hit.
When I got the card and it saw the poor performance I checked the Vbios. It was a bios for an rx 480, but a non reference model. I forced flashed it to the reference bios but that didn't help.
Can the wrong bios have damaged the card considering it was meant for an 8 pin connector and not a 6 pin?
The card is still under the 30 days buyer protection from ebay
