Hi there!
i have an issue about OC memory clock of my rig. I have 6 P106-100 mining edition and 5 gpu i can OC memory clock to 750 or more but only last one gpu i just can increase memory clock to 250 is highest.
When i try to increase more memory clock than 250 claymore 9.7 or any version will show me red error.

After increase memory clock of last one gpu to 250 my MSI Afterburner have laggy but if i set last one gpu memory clock to 0-200 Msi afterburner back to normal. And all my 5 good working gpus set memory clock to 700 there's nothing laggy with Msi afterburner. Just laggy or hang after i increase the last one bad gpu only

What i tried:
Quote
- change riser but no luck.
- unplug 5 good gpus and just let last one run but no luck.
- unplug 5 good gpus and plug last one gpu to motherboard PCI directly but no luck.
- try to plug in to my other gaming PC and no luck.
