Q code changes after enabling fTPM

Hello, I have a Ryzen 7 2700x on a Crosshair VII Hero mobo. All drivers and bios are up to date as of the posting of this question. With all the Windows 11 hype, I was curious as to if my slightly aged PC would be compatible with it so I ran the tpm.msc tool and it said I did not have TPM installed. I knew there was an option in the bios for it so I went ahead an enabled it, saved the bios settings and restarted the PC. Here's where things changed. The Q code normally reads AA and after enabling TPM, it changed to 33. From what I understand AA means "good to go, everything is fine" and 33 means CPU Post Memory Initialization. Now to be honest, I'm not entirely sure what that means, but everything in the system is running normally and I am getting no errors/crashes from any programs. PC boots up fine every time, it's just that I'm curious as to why the Q code changed to 33 and if I could get any clarification on what "CPU Post Memory Initialization" is. Thanks in advance.

clear/reset/create new TPM code

That may help but seriously, wait till 2024 before attempting this, and run 11 in a VM.

 

IMHO make the move to Linux....

Ok, well I cleared the TPM and nothing changed. Still has the 33 Q code when I have the fTPM enabled.

The code can mean many things, CPU fan not connected to the CPU fan header, etc. If the system works, I wouldn't be surprised if it is the fan header since you have an AIO. But that depends on the Mobo and what not. Anyhow, if the system works, no point in worrying about it. And for future reference AMD Ryzen 2000 and newer will work, I think Original Ryzen will as well as windows 11 will only use TPM 1.2 BUT DON'T quote me on that because I could be backwards here.

I have the Fractal Designs S36 AIO. It only has one 4pin plug that controls the pump and fans. It's plugged into the CPU fan header and the pump and fans are working normally. I'm beginning to think that this is an architecture issue with the BIOS. Just like when I start Ryzen Master the Q code goes to "d3". I restart the system and it goes back to AA. I needed to get some dust out of the case so this morning I cleaned everything off and while I had the case opened, I went ahead and reseated the RAM just to see. It didn't change anything but like you said, it's working normally so I'm not gonna worry about it anymore. The code doesn't make sense and the only change that triggers it is enabling the fTPM in the BIOS. I appreciate the help/suggestions. Thanks.

If the system functions as normal why do we care that it says 33? 

Corps aren't your friends. "Bottleneck calculators" are BS. Only suckers buy based on brand. It's your PC, do what makes you happy.  If your build meets your needs, you don't need anyone else to "rate" it for you. And talking about being part of a "master race" is cringe. Watch this space for further truths people need to hear.

Hello, it's not so much that I "care" as than I'm curious as to why it changed. Implying that I care makes it sound like I'm having a negative emotional response to the fact that two letters changed to two numbers while my system continues to run as normal and that's just crazy. I am however, curious as to why they changed.

Yeah, there could be a simple reason it is happening. Normally, pumps plug into AIO headers, so I wouldn't be surprised if that is the reason it is happening. Not saying it is, but something stupidly simple like that could be the reason. No reason to change it though, don't fix what ain't broken. I will likely update to Windows 11 as well, so with that said, we can wish each other a pain free experience....but that's about it. So good luck haha!

I tried what you suggested just for the hell of it, it only took 10 sec to move the 4pin over one header, and got the "no cpu fan" warning on startup, so I had to go into the bios and tell it to ignore the cpu fan header. It still throws up the code 33 after starting so I just put everything back to how it was again. I still feel like this is an architecture issue like with how it changes when I fire up Ryzen Master it changes to "d3". Anyways. Thanks for the suggestion. It was worth a try.
