Z790 itx issues

[Shadowarez]

Like the 12900KS issues thread I'm finding this platform just down right problematic I can't get Gen 5 because of Intel's First slot PCIe hardware fault. Now I'm finding if I have my nvme in top m.2 slot it runs the drive at gen 3 I drop it to bottom slot it runs gen 4. But the GPU runs at Gen 3. Is it just a platform of disappointment line GNs disappointment builds?

Considering switching out for AMD at this point since Intel seems to have hardware faults and PCIe faults bakes into the platform.

Does AMD have these issues with there itx boards PCIe dropping 1-2 generations?

Don't think I ever have that issue. RMA is out of the question?

 

[Shadowarez]

Yeah it's older then few months I reread the manuel there is a dip switch that turns the lanes from auto to gen 4/3 I can test the coupon my z690 board see if it still behaves the same.

 

[Shadowarez]

Well that fixed that issue far as I can see.moved it from auto to position 1

Hopefully that is the permanent fix for you.

So far it survived the stress tests. Wonder if AMD gets Gen 5 nvme right out the gate without the PCIe fault this platform has.

So what's the point of this switch? I thought it could be control via BIOS?

 

[Shadowarez]

Asus engineering at its finest, there is no option in bios other then the m.2_1 which you can set, there is no Dimm / Gpu post like i had on my x570 Dark Hero, from what i can tell auto this gen is horrible, i set the switch to position 1 and that forced the gpu to run full speed auto couldn't do that at one point upon boot up i seen a screen text say gpu in 8x mode i checked gpuz and sure enough it was pcie 8x but it was worse pcie 8x gen 3 then upon testing it dropped to Pcie Gen 3 x1 >< im going to have to redo the oc as well after the change iv seen hwinfo showing cpu pulling 1.65v to hit 6ghz on 2 cores

goodness this system does not want to be stable temps are in check not using AI Oc features, xmp, maybe i just need to set this system to stock and try tweak voltages swear the second i read the articles on the14900k having stability issues mine decided hey i can do that too i wanna belong ><

cant get more then 5 mins in Destiny 2 without crashes, Diabo 4 dont seem to care itll run regardless. im thinking it has to be the cpu having issues, the gpu has been copper modded temps are insanely good especially for the case its in (hot spot 64c core 56c) everthing is stock to rule out a bad gpu ill pull it out and put it through another stress test to double verify it can handle full screen 3d games.

Stock as in BIOS set to the Intel defined baseline and not the mobo's baseline voltage?
