I noticed on GPU-Z and in BIOS that my GPU was set at x16 4.0 but running only at x8 4.0. I tried to stress test the GPU with kombuster and GPU-Z but no change. I removed all other expansion cards and only have my M.2 boot drive in. I have all high performance modes on and have checked the PCIE power state in windows which is off. Lastly, I reset all BIOs setting and still its only running at x8 4.0. Nothing on the mobo manual or 3070 ti manual explains why this would be happening.
I get the card will work fine with just x8 lanes but I want to understand why it's not using all x16 lanes.
System specs
- Strix 3070 ti
-Dark Hero mobo - https://dlcdnets.asus.com/pub/ASUS/...53_ROG_CROSSHAIR_VIII_DARK_HERO_UM_V2_WEB.pdf
-1tb M.2 SSD (in slot 2) have also tried it just in slot 1
-Ryzen 7 3700x
-TX-750M Gold PSU
Any insight would be appreciated. - Maybe I am missing a setting in BIOs?
UPDATE: if I add another expansion card in the second slot instead of delivering x8/x8 it delivers x4/x4… I’m pulling my hair out here
SOLUTION: NO WAY was this the solve.... I literally just took out my GPU for the THIRD TIME but this time I blew out the PCIe on the mother board and lightly cleaned the gold connectors with Isopropyl. BAM running at x16 gen 4.
Thanks.
