TUF 5090: How do these HWiNFO voltages look? Also what is "GPU Unknown Rail (10) Voltage"?

Have been power limited to 85%-90% and decided to check HWiNFO. To me, the 16-pin HVPWR Voltage looks ok...but I don't know what GPU Unknown Rail (10) Voltage is. Should I be worried about that?

Have a Corsair RM1000e and am using the 12VHPWR cable that came with the PSU (never used it before).

I'm assuming you have the latest drivers and aren't experiencing the voltage bug. Not sure what that rail reading is but I have the same card here are my numbers idle and under load.

Idle.

What’s the voltage bug? Also it seems you have the OC model but really it isn’t much different.

From what I understand, the 16-pin HVPWR voltage should be as close to 12 as possible. Hope both of ours is ok. I’m tempted to check the cable but I don’t really want to unplug it.

Good to know the unknown rail isn’t just me!

Only difference is like 100 MHz otherwise identical and that shouldn't change anything on the HVPWR cable. Voltage bug can happen if you've played around with undervolting or overclocking your card with any of the older drivers. It can get stuck at a lower clock frequency. When I had the bug I noticed it would draw less power and run at lower mhz but still show full gpu load hence I mad a wild guess maybe that had something to do with your slightly low voltage on that rail. Reset and shutdown would not fix it, usually a full system shutdown and power off at the power supply would solve the issue for me. The new drivers resolve this issue... well they did for me.

What's your HVPWR like under full load? As long as its within a few % margin I'm assuming it should be fine. I just invested in a Wireview Pro connector just to have a little more info on what's going on with my cable.

Ahhh. Thank you for the context. Under load it's about the same!
