[SOLVED] Installed more RAM and PC not working properly.

[ForestArmy]

I have just installed an extra 2x8gb of 3200 corsair ram, adding too my identical 2x8gb 3200 corsair ram so i now have 32gb of ram and have been running into a lot of problems. Firstly my PC cannot install windows 11 when it could before as it now doesn't have TPM, i have been getting multiple blue screens with different error messages. One being ndu.sys, another being driver_irql_not_less_or_equal another being ntoskrnl.exe. Sometimes it runs fine and sometimes it crashes so I'm not sure what is wrong, it is detecting that i have 32GB of ram and i have gone into my bios and changed my tpm from discrete to firmware, this says it is now compatible to install windows 11 but on my windows device security i only have security processor and not the others as it says 'standard hardware security not supported' when it didnt say this before and i could install windows 11 before installing the new identical RAM.

Are you sure they are identical?

When running 4 sticks you often can't run them as tight as two. I suggest double checking the values, speed and timings. Manually set them if you need to. You might need to back them off a setting or two, and/or up the voltage a bit to make 4 sticks run right.

been playing on my pc and everything is running fine and i have the 32gb and the 3200 speed. The default TPM on my bios is discrete and it has always been discrete but i have had to change it to firmware TPM. It now has the specs for windows 11 so the only problems i can now notice is that firstly i still don't have the different device securities i use to have and only have security processor due to TPM and i don't actually have the windows 11 download and install option when i use to as it isn't 'ready for me yet' so something within my hardware or drivers must have changed somewhere?

I doubt they are identical. What's the model and version number of each kit?

Yeah found out the old ones are 4.31 and the new ones are 4.32. I guess this could be causing the memory issues?

Maybe, or you could give us the info I asked for. You might need to adjust the timings because you are using 4 sticks.

With different versions you mix different RAM. My experience is that 4.32 don't run very well with Ryzen. Mixing them with other versions and especially with 4 dimms it only makes it worse. If you want 32GB, get a 2x16GB kit.
