Constant Memory Problems

[finkangel]

First post here looking for advice for a problem with overclockers prebuild.

I bought a prebuild in 2019 and it ran with little problems until recently when i tried to upgrade the ram. Initially I tried to add 2 more sticks of ram to the existing but that was unstable and wouldn’t post half the time. I tried again by replacing the original with 2 sticks of 16gb, but ran into the same problems. After updating the bios and resetting through CMOS and few times it was still unstable, however now that i’ve put the original ram back in the problems persist.

Could anyone give me some advice on this issue, should I revert the bios back to its original settings? XMP has been enabled and i am testing without but 2400mhz memory is not ideal.

Specs:
Ryzen 7 2700x
zotac rtx2070 amp extreme core edition
gigabyte b450 aorus elite

original ram: nighthawk 16gb(2x8) ddr4 3000mhz PC4-24000C16

1st ram upgrade: crucial 16gb(2x8) ddr4 3200mhz CT2K8G4DFRA32A
2nd: crucial pro 32gb(2x16) 3200mhz CP2K16G4DFRA32A

Is it stable without XMP enabled? Have you tried increasing the voltage slightly to the RAM or tried different slots?

seems to be stable without xmp at 2400 but still testing, using slots 2 and 4 and changing them doesn’t seem to make a difference. I was hoping to use a higher clock speed for my ram than 2400mhz. Without xmp I’ll try increasing to 2800.

Update:

Tried multiple things with BIOS and diffrent sets of ram. In the end its stable running at 2800mhz using the original ram sticks. I appreciate all the suggestions but I have tried all these fixes multiple times (clearing CMOS, running memtest, using earlier bios). In the end I'm still unsatisfied with the overall performance of the pc and decided to get a new prebuild after 5 and 1/2 years of using this one, due to having to run most of my games on fully low settings with DLSS. My original aim was to increase the performance slightly with RAM so it would last me another few months but realising I would likley need to replace the motherboard and cpu, I just decided to go all out.

Thanks for the all help regardless.
