Aurora R12, PCIe training error

you are beta testing Windows 11

That looks like an RTX3090. Did you install an aftermarket video card, or is that the original OEM video card?

Check your power settings. Link speed goes down to X4 pending on the power settings. It should bump up to X16 once you put load on the video card.

If you want it always at X16 you have to disable PCI express link speed power management under the advanced tab of the windows power plan settings.

Yours does not stay linked at X16 with Link State Power Management set to off?

That is still not working for me. Did you ever come across your alternate solution?

I don't know how to tell if it is X16, but I am going by my low idle MHZ

GPU-Z will show you the link speed. I think the GPU frequency being low is a separate power savings feature.

Bus Interface?

Yes sir. You have something going on because you are linked at X16 but at PCIE standard 1.1 instead of 4.0.

I have seen this before: 1.1 PCIE speeds 

I don't know if there is a BIOS setting that affects this on the R13. On my R10 there's no settings and it is all regulated by the Windows Power plan.

I do know that AWCC tends to override the power settings, so that is another area to look at.

Also, you have REBAR disabled. If I am not mistaken the R13 supports REBAR.

If that is a Dell RTX 3080 than we have the same card. Mine does not change link or PCIE speeds when disabling Link State Power Management.

PC is Area-51 R5 and RTX 3080 is Founders Edition. If I start the render test the 1.1 changes to 3.0. I'm not sure what resizable bar is/does?

With what software?

Is the ePSA (outside of Windows) or instead ... something you found inside Windows?

I thought we were talking about an R13. On an R5 you will not have REBAR support. REBAR = Resizable bar 

Resizable bar support 

The 3080 can use PCIE version 4.0, but on that motherboard it will be restricted to PCIE 3.0.

Could be an issue with that. It's for sure a power savings feature that is enabled somewhere. Not sure what that BIOS has for power savings options.

I'm sure we can do better, the link state power management tab has nothing to do with lane/link speed. Although I've turned that off since win98 and it will effect gpu when idle-his gpu needs to be under load for full pcie link-its automatic-he is having link training issue because support assist believes those are x16 pcie slots-they are not-its well known dell uses x8  lanes since the R7, R8, R9 greedfest that eluded major media exposure-same mobo same everything for R9 new look-m.2 drives not pcie 4.0 on R10-3rd slot at x2-I installed a pcie 4 ssd in the gpu slot and achieved 7,000 only to yank it for oem dell 6800xt facebook has been paying them thru the nose-using gpu-z, downloading the directx3d driver should get things going-there are also command profiles pre-made for OC and CPU-the folks who provide us with.

I bricked a R7 modding the bios-I brought it back to life with a hacked bios on purpose to prompt bios guard to reinstall the backup-thats how I came up with idea of letting  dells own program insert the cpuid code and power update into the nvram-Ive been sporting a 9th gen in an R7 for 2 years-its a crazy amalgamation of a bios file from china, dells inhouse xps 8930 that I merged into R7 bios that booted and ended 3 hours later with my win10 pro wiped and installed under some tag from china lol-

it ran for a few months and like a dummy I didnt disable UEFI updates in bios and windows slid in firmware and no more post-I vowed to get back later and using an R8 chip,hardware programmer and some nvram hotsauce back in business.

so 1 pcie 4.0 cpu slot R10, if more than 3 m.2 ssd installed the pch slot runs at 8gts and intel fake raid a no go but software raid not bad but fast as weakest m.2 slot so switch cards good but no dual 4.0 cards work either which I believe the misrepresentation of actual pcie link speeds-even hwinfo gets it wrong.
