Thanks for your reply's guys, Ive been having such a bad time with these new gen cards... Ive only gotten to work like 1 out of 8 miners because of this problem, and I feel like Ive damaged so many cards without trying anything extraordinary.

Ive built several 390 and 470/480 rigs before so I am even more clueless about what might be happening here...


**********UPDATE. Here is what Ive tried so far:


HDD: Ive changed the SSD and reinstalled Windows

Risers: Switched and tested.

MOBO: Updated BIOS, swapped and tested, Biostar TB250. *******I can see a red box, on Biostar's CPU compatibility list, with the warning: "Please update system BIOS before upgrade your processor (CPU) to avoid system failure". Do you guys think it is possible to damaged a motherboard/GPU by using a Kaby Lake processor (i3 7100)? Even if it was only a few minutes before updating BIOS?

PSU: Gone from 1200 watts to 2x650w.

RAM: Tested 2400mhz and 3000mhz 8gb RAM kits.

Drivers ver: Ive tried driver versions: 17.7.2, and mixed drivers for 17.5.2

Virtual memory: 16000 to 32000 mb

Windows 10: PRO 64 bits, even tried installing every update available.

Polaris Bios Editor: I've been using the same Bios editor as Cryptomined and many other youtubers.

MOD: I used the already tested mod created by BuriedOne Blockchain youtuber (https://www.youtube.com/watch?v=uiPCwJV_ryM) and for the rest of the 4gb cards, Ive been using the 1625 and up mod as I think its less aggressive than the 1500 and up one.

BIOS: Ive tried stock settings for the bios and a tweaked version with HD audio disabled, all PCIE ports set to 2g... By the way, I even get the computer frozen while on bios sometimes, I mean, how and what am I doing wrong?

After modding the cards, I usually lose the capability to enter bios, when started, it runs directly to Windows and it gets impossible to work with 6 gpus, its like GPUs start getting progressively deteriorated after the MOD
