Random reboots

[Penfold7]

My son had a relatively old build of an AMD FX CPU and DDR3 memory. His mate thought it was too slow and they both cooked up this plan to use one of his mates motherboard, CPU and memory to speed it up. The replaced it all with an AMD Ryzen 7 5800x, an MSI x470 board and 16gb of DDR4 ram. They decided to do this late on a Thursday evening, but they couldn’t get it to boot. I told them that they couldn’t just use the OS that was already installed for the other hardware but he insisted he had done this before and it worked. Anyhow I researched this and realised they were trying to boot an MBR drive with a UEFI board and this didn’t work. They managed to enable CSM or legacy mode and it booted. It loaded loads of drivers etc, but it runs.
His issue now it that it randomly reboots 2-3 times a day. I’ve looked in event viewer and when it fails the error is A Fatal Hardware error has occurred,reported by component Processor Core logged by WHEA logger. Also he gets a TPM error the device driver encountered a non recoverable error with the TPM hardware.
His previous mobo didn’t have a TPM.
I’m not sure of the provinance of this new hardware he’s got and how long it’s been sat for. My idea would be to remove CPU cooler and redo the thermal compound and then back up the system and do a full reinstall of windows. In my experience changing this much hardware and not reinstall windows is just messy.
Anyone any other ideas??

Oh forgot to mention his PSU is good enough I think. I replaced a while back with a Seasonic GC650 80plus gold on the advice of philpower on these forums.

Clean install every time, Windows first, the chipset drivers second and never let Windows update before the chipset drivers have been installed.

When trying to boot Windows on computer to which it was not originally installed Windows tries loading the drivers for the previous MB and things go awry, in this instance to make matters worse the OS was set up on what is now obsolete hardware so small wonder it is showing TPM and other issues, see my canned info below for how Windows needs to be installed.
Once Windows has been clean installed you must then install first the MBs chipset drivers then the storage/SATA drivers and third the graphics drivers, the drivers can either come from a disk provided by the motherboard manufacturer or downloaded from their site and saved to a flash drive etc, this is a must and Windows should not be allowed to check for updates before it has been done as more often than not Windows installs the wrong drivers or in the incorrect order and this can cause all sorts of problems.

The reason why this procedure is so important, the chipset is what enables the MB to be able to communicate with all the hardware + are the first drivers that Windows looks for on boot.

What speed is the RAM and is it two 8GB sticks or a single 16GB stick.

What is the brand and model name or number of the GPU.

Thanks @philpower2
The RAM is Corsair branded and I think it’s 3600. It’s 2 stocks of 8gb.
His GPU is a Radeon rx6600
Glad you agree. Should I re paste the CPU, or just get the drivers and do a full reinstall of windows

[phillpower2]

The RAM is not appropriate for the CPU, AMD state here up to 3200MHz/MT/s and if you have DOCP/EXPO/XMP enabled the RAM will get auto OCd past what the CPU can handle and the PC will become unstable.

GPU is well covered by the PSU output so all good there.

Unless it was not correctly done in the first place I would not remove the CPU to repeat the thermal compound procedure, avoid unnecessary risk whenever possible.

Follow the installation procedure described in my reply #3 and see how you get on.

You are welcome btw

I’ll do a screenshot of what CPU z said about the memory

[Penfold7]

Does this make more sense.

[phillpower2]

Not sure of the need for the above in all honesty, the info only confirms that the RAM is not appropriate for the CPU and XMP should not therefore be enabled.

I dislike waste so see no sense in people purchasing RAM that is faster than what their CPU can handle.

Something to keep in mind for the future, a CPU must be compatible with a MB whereas the RAM has to be compatible with both the CPU and the MB, this because a MB can be compatible with faster CPUs than the one in your list of parts and MB manufacturers often state RAM speeds that far exceed that which any compatible CPU can handle, this is misleading at the least or dishonest at worst.

[Penfold7]

He can see if his mate has pc3200 or slower ram, if not we can give it back to him and get some money back and purchase matching ram. Will xmp need to be disabled manually or will system recognise it doesn’t need it.
Appreciate all the advice.

Also on the site I use, scan.co.uk, as it’s close to us, should I get single/dual channel or quad channel. I’ve not downloaded the mobo manual yetops:

[phillpower2]

The below so that you can get on with installing Windows and the required drivers;

Restore the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" “most stable” or on newer boards “optimized” please note that if you have both the “most stable” and the “optimized” options in the BIOS you should choose the most stable" option as in this instance the “optimized” settings are a form of overclocking that can cause instability.

Save the new settings, exit the BIOS, restart the computer and XMP will be disabled.

I’ve not downloaded the mobo manual yetops:

Don`t worry about new RAM just yet but golden rule #1 is to always have the MB manual close to hand.

[Penfold7]

Thanks again. Can mark this solved if needed. If problems occur after doing everything then I can come back.

[phillpower2]

No worries, we will leave the thread marked as pending and if we don`t hear back from you by Wednesday we will consider it as case closed.

Just downloaded the MOBO manual last night. Having a read through and it seems there are 2 CPU connectors. An 8 pin and a 4 pin. Ive never seen this before. I know only the 8 pin is plugged in. Does the 4 pin need to be in as well?

[phillpower2]

It should tell you in the manual but the answer is no, the extra one is for those who want to manually overclock
