Im still having problem with the freeze issue after doing some changing slot and replacing risers, changing drivers from 15.3 to the latest(cant control the fan), changing CM version from v6 to v10, checked the cables but there is nothing wrong, trying 4 cards from previous 5 cards running still freezes, doing GEN 1 from GEN 2 but all of them seems doesnt fix it. it still freezes. I removed the PSU thing since I have 1800w supply.
One thing I did not do it yet is reinstalling the OS because it would be my last resort and hope would fix it.

Also I noticed, after a couple of minutes when the CM runs, there is a cmd showing then it disappeared, several minutes afterthen the rig would freeze. Im really so confused because everything just started 3days ago, this R9 rig is running without any issue and I dont have any problem with it.

What I do now is Im trying to run it under SMOS and its running for 30minutes now, I will update this one later.
