RX 580 Possible broken temprature censor

[Guest]

GPU: XFX 580 8GB + Drivers: Radeon Software Crimson ReLive Edition Beta for Blockchain Compute

Core Clock: 1250 MHz

Memory Clock: 2190 MHz

 

 

I have a problem with my graphics card, (XFX RX 580 8GB) When I launch Claymore (dual mining ETH + Keccak) it will startup normally and after about 30 seconds the core clock will get unstable.

Resulting in a popup from AMD Wattman which states: Maximum GPU temperature exceeded and the whole system freezes.

ETH hashrate is at max: 26.7MH/s and Keccak at max: 220MH/s

These hashrates should be 31MH/s for ETH and 257 for Keccak (claymore is configured correctly)

 

In these picutures you can see that when the miner starts the temprature stays below 50C like it should because this GPU is watercooled.

And after about 30 seconds you can see that the core clock gets unstable along with FB usage.

 

Options I've already tried and didn't help.

• Flashing a newer bios onto the motherboard
• Disabling power saving settings
• Clean install of windows 10 64bit HOME
• Using risers.
• Swapping the card into different PCI-E slots.
• reinstalling drivers
• increasing voltage

 

What I think that possibly could be wrong.

• broken / damaged temperature censor
• incorrect / bad software control of the temperature censor

 

At this point I'm running at a dead end so that is why I'am asking for help here.

Hopefully someone is able to help me.

VRM overheating?

I don't really think the VRM is overheating, but I'am also not really sure.

I have little heatsinks on the vrm's and when i touch them they don't feel that hot. Same said for the backplate. 

 

Might be handy adding that this setup has worked for over a month and just now is running into issues.

 

Thank you for your reply I will look deeper into this.

VRM isn't overheating what I did notice is that the RAM on the left side of the card gets really hot. I can't hold my finger on the heatsink for not longer than a second. Tried to adjust the fan to blow a bit more on those chips. But didn't seem to solve the issue.

 

Someone else got any idea what is going on?

Found the issue and managed to solve it.

 

Voltage problem of some sort.

Greatly undervolting the card managed to solve the problem.

currently using SMOS and my hashrates are now: 30.2MH/s for ETH and 241MH/s for keccak.
