Question GPU running at x8 instead of x16

[ron2456]

My new gpu is running at x8 1.1 instead of x16 3.0 on my motherboard Gigabyte AX370 Gaming Rev 1.x even though if its connected to the x16 slot. See the screenshot

How to solve this issue?

Specs:

1. R5 2400g
2. 1050ti Asus
3. AX370-Gaming
4. 2x8gb Crucial 2400 oc'd to 2666
5. 1xWd Blue and 1xEvo 250Gb
6. 5x CM Case Fans Red Led plus 1x CPU Cooler
7. Corsair CX450 80+Bronze

EDIT: Just saw that its hopping between 1.1 and 3.0 but stay at x8

Hey do you have any other cards in any other PCIe slots? Capture card?

Found out the reason, ryzen 2400G has only x8 pcie lanes as a result gpu is running at x8. Btw will this cause any issues like low fps or something?

I see! Interesting... Regardless, running at 8x shouldn't show any real performance difference, maybe 1% in some games.

Oh then it's okay. Looks like I need a new CPU now, will the r5 1600 be okay?

Why do you need a new CPU? I doubt your CPU is the limiting factor in gaming performance.

It will, but you should just get the r5 2600 which is the newer version.

Also, I believe that CPU will require a bios update to work so keep that in mind!

Wait a few weeks, see if your board gets a bios update, drop in an R5 3600 if it does.

Yes it seems Gigabyte dropped a bios update on the x370 lineup for 3xxx support. Release notes state:

1. Update AGESA 1.0.0.2 for 3rd Gen AMD Ryzen™ CPU full support.

You can get a new CPU if you wish but it won't have an impact on your gaming experience with that graphics card.

The difference between the bandwidth of x16 3.0 and x8 3.0 is not a meaningful number even for a GTX 1080. The GTX 1080 has a 320GB/s bandwidth and the number for your card, as shown in the GPU-Z shot, it is 112 GB/s. PCIE 3.0 bandwidth at x8 is 7880MB/s.

did yyou check if you use the rendering option in gp-z if it goes the 3.0 x 16 .

It goes to x8 3.0 because cpu has x8 for gpu, x4 for sata and m.2

you might have to look for another cpu and in the same time a gpu .
