GPU hashrate drops (Small reward of 0.0005 BTC)

[StartMiner]

Hey guys, I'm recently optimizing my rig and I noticed that my first GPU is a bit unstable. The usual rate should be 28,7 but all couple of seconds it drops to 23 and therefor gives me an average of only around 26. I already changed the PCIE riser but it didn't work. My PSU is also not overloaded (750W and I'm taking 310 out of the wall). I noticed that the GPU wattage is also unstable. This phenomenon also occurs while not overclocked. Has anyone an idea? The person who solves this problem / gives me the right hint for solving the problem will get a small reward of 0.0005 BTC.

Could be caused by overheating induced throtteling. Did you check the GPU and CPU temps?

Yes, already checked. I always keep my GPUs at around 55-60°. The CPU is at around 35°

the first gpu is normally used rendering the display. even in teamviewer or any remote desktop program. you will see the rate go back to normal if using the api to monitor your hashrates.

Ok, if you tell me how to use the API to monitor it and if it is really stable after that then you will get the reward

I had a similar issue, swopped out the riser and it fixed my problem. Give it a try

Already tried this (as written in my post)

the first gpu is normally used rendering the display. even in teamviewer or any remote desktop program. you will see the rate go back to normal if using the api to monitor your hashrates.

So I checked the hashrate for the time the hdmi cable was not connected but still no constant the rate. The drops are not that hard while not using the monitor but still go down to 26.
