Yeah I believe A0 is standard normal boot. 30/40 are some type of awaken from sleep mode. 

Instead of seeing A0 if you let the computer fall asleep it will not wake back up to A0 it will be a different code. Nothing wrong just that it was awoken and it likely won't go back to A0 until restarted. 

Thanks, I appreciate the answer but you don’t really sound sure. I called customer support and even they didn’t know about the Tvb settings and post codes.

And this z590 ftw splash screen is a bit of an eye sore

Sorry, I was trying to help from mobile. My unsure-ness was about the TVB, so that's fair and I'd recommend listening to some other folks who seem to know more about that.
 
I can help, however with the beeps. There are many beeps, different beeps for different things. Without specifically hearing YOUR beeps, I cannot say with 100% certainty which ones you're referring to. For me, I was thrown off by about 5-6 short beeps before the final longer/louder beep (that one indicates POST is complete). The shorter ones sounded like it was trying to tell me something in Morse code. According to the manual, "A POST beep may indicate a successful POST or various tones for USB initialization, while other beeps may indicate an issue during the POST process. Please see Page 153 for more details." Those short beeps I was talking about were the USB initializations. I was able to confirm this by plugging and unplugging things and counting the beeps. I've never had a board that beeps at me like this before (a feature which can be turned off I think, but I've grown to think it is sort of adorable).
 
Last night, I heard a different set of beeps, the kind described on page 153 of the manual. These are longer, angrier beeps that happen after the USB initialization beeps. I had 5 of them and the code the indicator gave agrees with page 153: "No Console Output Device Detected". This was because I put in my brand-spankin-new 3080 ti in last night and tried to turn on resizable BAR (and CSM off). I skipped the step where I have to convert my legacy windows install to UEFI...and there's also an issue with these new GPUs where they don't output video during BIOS/post...there's a new vBIOS beta to try, but Precision X1 says I have to disable CSM to install vBIOS...so...I'm not sure how that's going to go, but I'm going to start with the Legacy-boot to UEFI conversion tonight and see how far we get after that.

hmm... still looking for that darn disable button for the z590 ftw splash screen at start up
 

confirmed that there is no way to disable the splash screen in bios

double confirmed that there is no way to disable the splash screen in bios

Something else I've noticed, no matter what I do it seems my cpu runs at 5.1 all cores but I cant get the two best cores to run at 5.3 or even a single core to run at 5.3.  I've got a 360 rad cooling the cpu and great airflow im well under 70C for single or dual core applications.  Any ideas at to what could be causing this or is it normal.

 
I had this issue too! Turn off Intel ABT (advanced boost tech) in the BIOS Advanced CPU settings section. It is "boosting" to 5.1 all-core. If you set up a ratio OC and your temps are good, you can have it run 5.3 on a couple, 5.2 on a 3-4-threads, 5.1 on 5-8, or something like that, depending on temps. With adaptive voltage setting, it drops cores down to 800Hz at low usage, and cranks them up over 5GHz (5.3 sometimes, etc.) when needed. 

Nike,
Thanks Nike, Ill play with the ABT,  (how many F'ing version of turbos can one chip have?) 
 
rblaes,
Yeah I dont know why they didnt give the option to disable the splash screen, or at least just make it black.
