When I run DSTM or EWBF I have one card that starts ok but then goes down very fast to 1/2 hashrate.
NVIDIA Inspector shows very small (about 30-40%) usage of MCU on that card.
If I run ccminer (any algo) - all is fine, all cards are equal. So it seems to me that this is an equihash issue.
Please check card 1. Sometimes it shows shares like .. That card is totally equal with 7.8.9 GPUs, so it must give 750 h/s
Defective card?

@Shodo if that card alone run at max speed with out problem i doubt is Defective card or riser ... single issue what came in my mind is Power or miner have issue suport 10 card. Anyway i see you have 10 card, try to run with lower batch like 3 card, 4 card, 5 card & see if that wierd bug it happen & if it apear at some higher combo. IF bug is about to many card then single solution what i have in my mind to run 2 diferite miner sesion like 5 card to a pool 5 other to other pool ... or in any stable combo you find ... same i not think it need to be full restart your rig just stop miner & restart is inaff for testing special i see bug it strike fast under 2-3 min ...
cheers
