Okay so, couple things. I recently bought some 128gb ram and new CPU and put it into my b550 pro4 ASrock motherboard. My bios is not completely up to date, but updated enough to play with the cpu just fine. It's like bios p3.40 or something very close to that. Now here's my issues.

DIMMB1-2 doesn't work ater replacing my old ram and old cpu (WAS A Ryzen 3 cpu). Half my ram is in, but the other half won't work. It's not faulty ram, cause I tested all the sticks in the 2 ram spots that do work, and they all work.
So i went and looked it up and got no solid answer. I got glimpses of changing timings and overclocking and that my ram wasn't good enough, etc. When I use a SET XMP profile, I get sent to windows, which is great, except randomly ill blue screen? And my programs randomly close?
Then because of my drive being not partitioned right (For whatever reason, set to MBR and i need GPT) i can't turn on secure boot, because it asked for something else to be turned off, but because WIN 11 REQUIRES secure boot, I can't upgrade all because of my 1tb drive, that I know have to format into a GPT drive. I'm just so lost and mentally drained from this and it's getting to me. If you have tips/ help please lemme know, cause I really REALLY don't wanna have to replace my whole pc. Also trying to go to win 11.

Apparently, non-overclocked ram that my motherboard supports is 3200mhz and I have 3600mhz.

Here are some specs to help anyone out:
ASRock b550 pro4
Amd ryzen 7 5700x
4 sticks DDR4-3600 trident z royal crystal
RTX 3070TI FTW
1TB solid state
2x 8tb hard drives

Please lemme know if you need anything else!
 
PSU: make, model, wattage, age, condition (original to build, new, used, refurbished)?

Start simpler: no over-clocking, etc.

Just the boot drive without any immediate partition changes to Windows or added drives.

Objective being to first establish a stable system. Then work on performance tweaks that are known to make a difference.

Small steps changing only one thing at a time.

Watch the system logs: Reliability History/Monitor and Event Viewer for error codes, warnings, and informational events related to system problems.

= = = ==

Check the motherboards's User Guide/Manual.

Some motherboards require that the first physically installed RAM be placed in a specific slot. Typically DIMM_A2.

There are variations.

Sometimes the installation requirement is clearly presented, in other cases it may be in the fine print or barely noticeable in some diagram.

Plus there are often other notes, warnings, etc. in the fine print and/or BIOS settings.

= = = =

Take a break and then read/reread your way throught the Motherboard's User Guide and Manual to double check everything.

Do the same for all installed components.

Ensure that devices are indeed supported, that all drivers (direct from manufacturers) are up to date, that configurations are correct. Check everything.

Hopefully just some error of omission or commission.
 
Here is the ram support QVL list for your motherboard/cpu combo.
AMD ram support depends not only on the motherboard, but also on the cpu.
https://www.asrock.com/mb/AMD/B550 Pro4/#MemoryVM
This represents ram that has been tested, Others may work.
It seems that for 128gb, 3200 speed is the best that can be supported.

Is all 4 sticks from the same matched kit sold in the same package?
If not, you can expect issues that may or may not be resolvable.

When you think the setup is working,
Run memtest86+
It boots from a usb stick and does not use windows.
You can download it here:

Some motherboards will run memtest from the tools menu in the bios.

If you can run a full pass with NO errors, your ram should be ok.

Running several more passes will sometimes uncover an issue, but it takes more time.
Probably not worth it unless you really suspect a ram issue.

Hopefully so! I'll do what I can and see what else I can find.

Psu: EVGA 1000 GT supernova (used i believe, i bought it off a friend who custom built this PC. (I changed the ram and cpu after purchase from them)

Lemme double check the manuals and all that, cause I did see that 3600mhz ram is on the list, it just says 3600 (OC) so. Just wanna make sure it's getting the most of my purchases.

All ram is from the same place, and same package, yes. So I shouldn't be trying to up the DDR4 ram to 3600 in bios, got it. Keep at 32, but will it run 4 sticks?

Ill double check that program, thank you.

That's a nice lookin' motherboard you have there !
Yeah, UEFI has been a thing since the 2010's.
It was the reason why my GTX 780 wouldn't boot with my 1st DIY board, an ASRock A785GM-LE/128M (AM3 Socket).
Formatting for GPT isn't a big deal. Just make sure you select GPT - UEFI (non CSM) when creating your Windows 11 installation USB. If you're using rufus, you can't miss it.
