My rig has one GPU with very high and strange hashrate

As depicted in the screenshot below:



Sometimes (several minutes) that GPU suddenly gets a very high hashrate. Is this behavior problematic? If yes, how to fix it? Reduce memclock?

I'm using Claymores 10.2. Both of the six GPUs of my rig are ASUS DUAL RX580 8GB with Hynix memory.

Thanks in advance.
