I believe you can limit the max frequency. I may also test that, however I want to test a target temp first. I also need to find my Kill-A-Watt to measure system power. I do wish I had access to SPEC 2017.
Grabbed a used 7950x to go along with my open box x670e taichi 😂 the disabled cores on my 7900X were bothering me this time around.
How are there already used 7950X's for sale? FOMO over Raptor Lake?

Sounds like it. It was a guy on ebay, description said he used it for a week and switched to Intel. I can’t judge because I’ll be selling a three week old 7900X shortly.

| This was working fine for weeks. All of a sudden on boot it will not use the 3090TI (you can tell as the text gets big) Windows works fine useing it, and the video card, but linux is a black screen as it will not use the 3090TI |

I don't care about their support for linux. Why does the bios not use the discrete card, even though it is set to do that . It used to work, now it does not. They ignore that.Seems this type of response from them is pretty normal.

Gigabyte has a new bios revision out, F8b, but it's still AGESA 1.0.0.3a, so I have no idea what they've changed.
Nothing to do with kernals. Current problem is that BIOS only uses IGP , even whenMark did you update kernels?
Try booting with the older kernel that worked before and see if the problem is still around. I've had weird problems like that before...
Or reinstalling the Nvidia Linux drivers. That's fixed problems I've had with Linux not using the GPU before.
I know the labor market is still tight, but I didn't know companies were still willing to hang on to trash employees like this.I have to add this. I have 2 670E Taichi motherboards. All was going fine, until one bios version stopped using the discrete card (a 3090TI) and started using the on-board IGP, you could tell by the huge graphics and text. It also was a black screen in linux, but I figured that out, use the IGP port on the motherboard, install older drivers then switch back to using the 3090TI. Well, windows and linix are fine, but the boot sucks with that big ugly text and graphics. First, here is my ASRock support description. (before I figured out the linux problem)

And I replied that the bios was still using the IGP even when the bios is set to use "PCIE discrete card" as the primary.
And here was their reply:

Which part you did not understand “ASRock does not support any Linux OS”
to me
ASRock Tech Support
Open Monday to Friday from 9:00AM to 6:00PM PT.
What a nasty reply. I might be done with ASRock boards from now on.
No option to disable it? The Asus line of X670E boards recently received unofficial beta BIOSs that now have the option to disable it. Maybe there is a beta BIOS from ASRock with the same option.Nothing to do with kernals. Current problem is that BIOS only uses IGP , even when
bios is set to PCIE.
I know a few on Overclock.net that bought multiple just so they could find one with the best cores. Could be one from them they deemed unworthy.How are there already used 7950X's for sale? FOMO over Raptor Lake? I won't sell mine a second before I get ahold of a 7950X3D
Have you tried any EXPO memory ? For me, it worked like a charm, even though Intel memory I had, it would run way below spec.I'm having as bad luck with 0803 as I had with 0802, they refuse to run anything but JEDEC RAM speeds/timings. Back to 0801 for now
Working on tightening up my timings at least. I'll soon have to read some theory about it, since I think some of them are suppose to have certain relationship to each other, for now I'm only lowering them.
IMO AMD’s biggest weakness continues to be bios/uefi/microcode bugs. they definitely have not learned from previous launches. The platform needs to be rock solid from day one. No random BSODs or bugs. If you sit 2 years on a chip and launch $200-$1,000 boards, you need to deliver that experience. .
Yep, it is even worse for me. My ASUS board thinks the GPU isn’t present. Windows finds it just fine. On occasion it does show the boot/bios screens.Nothing to do with kernals. Current problem is that BIOS only uses IGP , even when
bios is set to PCIE.
I feel like this is largely board and board vendor dependent. I haven't had any notable issues on my Gigabyte board that I didn't cause myself. If I was the type of person who was content simply turning EXPO on and calling it a day, I'd have had a flawless experience.
But nooooooooooo, I have to try to screw with every possible setting and tweak all the things.
It's the cop out card for many companies' customer support: "Use unsupported OS? Can't and won't help no matter what."I don't care about their support for linux. Why does the bios not use the discrete card, even though it is set to do that . It used to work, now it does not. They ignore that.
This box is windows/linux dual boot. The problem is BEFORE is starts to load the OS, its not using the discrete card at that time.It's the cop out card for many companies' customer support: "Use unsupported OS? Can't and won't help no matter what."
Best to pretend to use a supported OS an explain the issue in that context. Though going by the descriptions so far it does sound like AMD may have done some incompatible UEFI changes in AGESA that are not yet supported/expected by the Linux kernel which is very disappointing to hear.
Indeed. And laptops are notoriously affected of this as well. AMD improved a lot since last year, but it seem that still didn't prepare the launch of the iGPU on AM5.This box is windows/linux dual boot. The problem is BEFORE is starts to load the OS, its not using the discrete card at that time.
Nope, I had to order from a limited selection at the time and I can't return by now I think. Though the RAM seems excellent so far as long as the BIOS support continues or is fixed. This is the kit:Have you tried any EXPO memory ? For me, it worked like a charm, even though Intel memory I had, it would run way below spec.
