Claymore miner crash with dummy plug

[Fr0st975]

Hello All,

Something strange happen with my mining rig, it very stable as long as there is a monitor plugged into the first GPU (uptime 1 month+) but if I unplug the monitor the first GPU stop to mine shortly after.
So to solve this issue, I bought a dummy plug on amazon and plugged it on first GPU. But now the rig isn't stable anymore, It randomly crash .

GPU HANG on Claymore miner and as I configured the restart script (reboot.bat), Claymore try to restart the rig but it remains stuck on the windows restart blue screen and the miner is no more reachable. I have to physically reboot the rig.

Is the dummy plug can be defective ? is there a way to run the rig without a screen or dummy plug ? Has anyone ever encountered this kind of problem ?

Thanks for your help.

Here is my rig specs:

Crucial DDR4 4 Go 2133 MHz CAS 15
MSI Z270-A PRO
Intel Celeron G3930
3x Sapphire Radeon RX 580 Nitro+ 4 Go
Kingston A400 120 Go
Corsair HX1200i - 1200W

Claymore miner 11.0
Windows 10 Pro 64bits
AMD Beta Blockchain Drivers
MSI Afterburner (core 1200 mem 2100 fan 70% undervolt -96v)
Cards not modded

your clocks are too strong.

core           1175
mem         2075
fan            70%
undervolt   -85v

see if this helps

Thank you for the update but how do you explain that the rig never crash when a monitor is plugged in and become unstable when I use a dummy HDMI plug ?.

Do you really think it's because of the overclocking ?

Bad dummy plug maybe?

[Fr0st975]

Yes maybe. I'll buy another one and try it but I would like to know if someone already had this problem before cause I suspect that it comes from elsewhere.

Thanks
