RTX 3080 Running at 2X instead of 16X

[mx62]

normally its a electrical problem
first to do:
test gpu in another pcie slot
second test the gpu in another pc
third re-seat cpu
fourth test cpu in another board
if none above tell where the issue is
rma board if you can of course

Thank you guys for your replies. I will try to reseat the CPU today. I will let you know of the results. I did try the RTX 3080 in my older, 4 year old PC (Asus RoG Maximus Hero IX motherboard with Core i7 7700K processor) and it works perfectly, immediately shows as x16, only the Gen speed changes on the go depending on the active/inactive render test, which is how it should work. Someone here mentioned that x2 PCI lanes are a power saving feature, I highly doubt that. In my opinion lanes are either open or closed, so x2 in a x16 is a major problem. Thank you again I will get to work.

from my point of view the driver 457.30 does not support the rtx3080 -- just use the newest one

I do not know about the OP but I can say Negative, I am running 466.27. Same issue. Stuck at x2.

Okay, so the CPU re-seating only took me few minutes. removed the cooler, opened the lid, blew the dust (if there was any) off of the CPU and the socket, re-seated the CPU, applied a bit more Thermal Grizzly thermal paste as I thought it was not really enough, reinstalled the liquid cooling. No change. Still running PCIE x2. Out of ideas. It must be the motherboard is garbage. Asus Prime Z490-P. I only own this PC with this motherboard for about 2 months. Behaving beautifully to it, never been dropped or bumped or anything like that, in a clean environment. I am pretty sure Asus Maximus would not have this issue.

i too do not think this will help too much but if you dont know your drivers there is problems ahead.
if the bios says x2 i think the problem is cpu which op´s is delidded or motherboard =old bios or not supported?-manufacturers fault.

best thing to try the gpu in other motherboard or pc from a friend. only then ya know for sure if the gpu is faulty

you on the other hand got much newer parts where everything should work from the getgo.
did ya try pci-e 3.0 in bios?
and i would open your own thread because answers get mixed up

Gotcha. Yes this was the ESL Tournament PC from Currys/PC World UK. It came with the Gigabyte RTX 3070. Bought another PC from Gladiator PC UK with the RTX 3080 and I just swapped the cards. I put the MSI RTX 3080 Suprim X in the ESL Tournament PC (Motherboard: Asus Prime Z490-P) and it happened immediately. Ever since then, both of my cards running at x2. I can't change the lanes in BIOS, it's greyed out I think that is just a reporting tool. It reports the number of PCIE lanes the PCIEX16_1 is using. And yes I did try to change every possible option I found in BIOS to Gen3 (PCIE Speed,etc.) I have never seen this problem ever

 

[basco]

did ya flash for rbar support or changed the option to on or off?

I did Flash the BIOS with the newest version from the Asus Support website. I just restarted the PC, went to BIOS, turned the Resizable Bar Off. No change. Still at x2. Amazing right? Riddle me this!

 

[basco]

you know it already if the gpu works in another pc then motherboard or as last option cpu.
you said you have 2 pc´s = are the cpus or motherboards interchangeable-yeah i could have asked same socket ?

i just say this because i think ya tried everything else already

quote: Ever since then, both of my cards running at x2--are ya telling me even after putting the newer card back you have the prob now on both?

Correct, both GPUs report X2 lanes only. It's almost as if it was restricted somehow by the motherboard. But both GPUs report X16 lanes in the older PC - Asus Maximus Hero IX. They are sadly not interchangeable. Asus Prime Z490-P (NEW PC) has LGA1200 CPU socket and the Asus RoG Maximus Hero IX (OLD PC) has LGA1151 CPU socket. Therefore I can't verify the CPU.

had my 750 ti running at 4x instead of 16x about 4 years ago when i stupidly bent cpu socket pins on my h61 board trying to clean it not realizing it doesn't get dust because it's well covered by cpu and you don't need to ever, though it did look like that and it also caused my 2nd ram slot to fail and would just get 3 beeps with both sticks plugged in

And needs 11th Gen CPU to use PCI-e gen 4.0

Hey, old Thread but never concluded. I have a similar issue and just wondering what was the fix? CPU or motherboard?

The fix is to start your own thread instead of hijacking an existing one.

Well it was never concluded. So, if stumbling upon such a thread with similar query, it is good to know how to resolve

Bunch of inconclusive guesses, which none of them were right.
Not one of them thought of the NVMe ssd being the culprit, as the other motherboard tested didn't have NVMe, so it showed x16.
A motherboard as old as Z170 has NVMe drive taking away CPU pcie lanes from pcie gpu, that is why it's showing x2.
It's perfectly normal, my z370 does the same.
I compared to similar hardware fire strike benchmark, i didn't have much less score.
A more powerful gpu like 2080 ti, i would be more worried.

NVMe takes four lanes..

Had this issue with my 4070, it was not seated in the slott fully.

[Problem Description]
Subject: the proplem in bios z370-a prime in slot pcie give me just 1x
Welcome
I have a problem with my z370-a prime motherboard

The problem is in the bios with the graphics card slot, I have a graphics card 3070 and an i7 8700k processor
Among the experiments is a 1060 gtx card


The important thing is that I have a problem with the number of lanes in the card slot. There are 3 ports on the motherboard, the first one gives 1x
The second gives 8x

How can I make it 16x? I reduce the frequency of the ram to 2133, although my ram supports 3200 and its type is gskill rgb


When I increase the frequency of the ram it returns to 1x

I have reached the problem after a long trouble. It is not easy. Updating the bios is the last and before the last 3003 3004. What is the solution, in your opinion? This is the WhatsApp number if you want 0546124981

Give me a solution

At what speed does motherboard connect the graphics card if you do not use the nvme drive (have you tested it)?

ok

In principle, I separated everything, only me, the processor, the mother, the RAM, and the card without any hard disks. The same problem gives 1x. I reduce the speed of the ram back to 16x, and the board supports numbers ready for the ram.

nobody suggest this yet: reset your bios

I think the problem is the connection between the GPU and the slot.

I tend to agree as it's been the only cause of this in the past for me, including with a riser card.

I'd remove the card, and gently clean the pci-e connector with isopropyl alcohol, and completely remove the motherboard, turn it outside down and use a a toothbrush with isopropyl to clean the slot out. Starting there will at least eliminate some random crud causing the issue.
