Frustrating working with my 1080 FE. Runs great at 2126 @ 1.04v. But going to 2138mhz tanks the core voltage to 1.02v and the driver crashes. I was thinking of flashing that Palit bios with the 99w pci-e and 175w 8 pin.
And unfortunately I didn't know about the shunt resister mod when I got my card and I don't really want to take apart my water loop and disassemble the block to do it.
Here's my opinion, which doesn't match "max published spec" for an 8-pin but it's been my experience that 200W for an 8-Pin is considerably higher than ANY STOCK value for an 8-pin. Although the wire spec may handle more power (looking strictly at wire gauge and number of grounds) I'm not sure if the power is reliable at that point due to the PCB traces on the GPU. Why would GPU vendors ALWAYS limit an 8-pin max power spec to under 200W and add a 2nd power connector on some models.. Maybe you could push it to 220W but I really wouldn't go NEAR 250W as I don't know if the cards could handle that much SUSTAINED power (not just a quick power spike).
Note the power section that states 75W(6pin) 150W(8pin)
But I have successfully pulled 108W from a 6-pin and 200W from an 8-pin without issue... 250W+ on a single 8-pin, I just wouldn't even "go there" it sounds risky.
Note the 12V yellow connectors on a 6-pin are IDENTICAL to an 8-pin...
