I bought a 3rd graphics card from Sapphire, RX 5600XT Pulse. I alredy have 2 same model. This one was cheap and I made a windows only gaming rig.
Even this 3rd card instead of PCIe 3x16, it show 8x. Not a problem, they output the same results with usual statistical variations (all in line with general results).

I'm starting to think that something is wrong with the 2 mobos I tried them on, X370 + 3600X and B450 + 2600.
Both cpus are capable of PCIe 3 16x.

I tried multiple OSs and programs, all showing the same 8x.

Other cards show PCIe 3 16x. I am truly puzzled. Makes no difference, but on an old i5-6xxx they are reported 16x.
Old i7-3820, 16x.

Is intel beating Amd on its turf? 🤣

Is the slot on your motherboard actually an x16 slot? A lot of times you can have a full length slot and it only have pins for 8x, 4x , or even 1x. Check the slot and see how many pins are in it.

Yep, the PCIe lanes are the ones of the slots connected to the cpu.
I'm not concerned, it isn't affecting the results one bit.
IIRC a RTX 2080 isn't maxing out the bandwidth of a PCIe 2.0 16x. Thus 3.0 8x is totally fine for this card (like a 2060 performance). It's 6GB GDDR6 192 bit.

I understand that it's not a performance issue I'm just more curious if that 16x slot is actually wired for the full 16 lanes. More just morbid curiosity

I'll have to check the cpu socket.
If it's not an error of some sort on the BIOS-Cpu-program, probably a broken lane. And that can be, absolutely.
Tomorrow I'll pester my dad to test it 😀 What are dads for??? 🤣

I'll also check the second motherboard.
It makes non sense. Also it could be a dead demux.

Not the CPU socket you need to check the pci Express slot itself. Not all full size slots have all the pins populated. Asus has some mid range Intel b850 boards with full size 16x slots but only wired for 1x and the rest of the slot has no pins.
Would you mind posting a picture on the 16x slot?

Ordered a pack of 600 colored jumpers ... set for life! 🤣

Sorted some of my parts shelves. Much better than before.

Ordered a 16GB eMMC module for my Le Potato. Not 100% sure what I'm going to use it for now.... Portable SDR station? Dedicated DOSBox machine? OctoPie server for one of my printers? Either way, eMMC is faster than an SD card. I do like the Le Potato, similar to Pi 3B+, but less power draw and 2GB DDR3 RAM vs the Pi 3B+ 1GB DDR2, same basic footprint.

Released ByteAether Ulid v1.3.0.

Did quite an overhaul on the generation/creation part of the ULID. Better than ever before! 😀

I tested one GPU with Z75 (3rd gen i-5) and Z87 (4th gen i5), both PCIe 3.0 x16 lanes.

GPUz detects PCIe 4.0 @ x16 running PCIe 3.0 @ x16 ---> values that never change, not at idle or 100% under stress. With 2n x16 slots it is detected running @ max speed allowed (both PCIe 2.0 @ x4) and results are lower than expected. But consistent between them.
I tested the GPU with 3DMark 11 and results are consistent with other cards' results. This is probably just a glitch and I should probably stop wondering.

HW monitor is the same.
IDK how GPUz and HWMonitor work but probably they use the same system to check lanes? If I'm wrong correct me, I'm clueless on this subject.

My guess spans from m/b bios to gpu bios.
There have been many updates and who knows if by flashing the latest version I just introduced a bug.
