i tried to flash the BIOS of the Card but the tool provided by Gigabyte didn't work at all. I know there won't be a noticable difference (about 1 % difference i read somwhere) but i paid for 16 lane support so i kinda want to have that

It runs on 8x no matter the configuration. I know there is a problem with the card. what i'm trying to figure out is WHAT the problem is ?

BIOS is updated (yesterday),slot configuration is 100 % correct and as i mentioned the card isn't even runnning on 16 lanes when it's plugged in in single mode (only one card)

i just did, it's set to Gen 3.0. couldn't find any specific setting for the actual lane count

Yes, both under load, tested with 3dMark and GPU-Z. The board support 16x on both slots, the previous board did too (i double and tripple checked the correct configuration) The M.2 is plugged into the dedicated Port on the Motherboard, i noticed no difference what so ever

it doesn't matter because even if it stole 4 lanes you can easily calculate it: 2 GPUs on 16 lanes = 32 lanes + 4 for the maybe wrong M.2 = 36 PCIe Lanes needed. My CPU provides 44 PCIe 3.0 Lanes

I didn't have an M.2 on the previous Motherboard and there is no way it's in the wrong port

Hey folks, i wondered if you could help me with a bit of trouble shooting. First, this is my rig: OS: Windows 10 Pro 64 bit CPU: Intel i9-7900X RAM: 32 GB DDR4 3600 MHz Corsair Dominator Platinum MB: ASUS TUF x299 Mark 1 GPU: Gigabyte GTX Titan X Drives: Samsung SSD 840 EVO 120 GB; Samsung SSD 840 EVO 1 TB; Samsung M.2 SSD 970 EVO 1 TB; WD HDD 2 TB PSU: BeQuiet Dark Power Pro 11 1200 Watts So here's the problem: Even though i switched out my motherboard, memory and CPU my second GTX Titan X is still running only at 8 PCIe 3.0 lanes instead of 16. My previous build was the i7-5930K, an MSI X99s Krait Edition Motherboard and Kingston Hyper X Fury 2133 MHz RAM. Both builds had more than enough PCIe 3.0 Lanes available and i remember when i first assembled the system both GPUs ran on 16x but i don't know when it stopped. So in summary i changed the Motherboard twice (once for testing), i switched the memory and CPU and switched the Slots for the GPUs and even tried the one that's causing problems in single mode in the same slot the other GPU runs on 16 lanes. I never reached 16 lanes on that card again. For some reason the two cards have different BIOSes but i don't think that this causes the problem. Thanks in advance for your help.
