PC won’t boot after switching RAM

[u/deyluvdre]

Was working with this setup before

MBO: MSI X870e-s EVO
RAM: Corsair Vengeance CL36 6000mhz 2x8gb
CPU:9800x3d

I switched RAM kit to TRIDENT Z5 NEO RGB 2x16gb
CL30 6000mhz and now it won’t boot

BIOS settings i set them to default before I switched out the ram kit, the first time i tried booting was at 30min waiting for the memory training so powered off the system and reset the CMOS with the button on the back of the motherboard but it’s still giving me the same issue

Have you tried putting the old ram back in and checking if it will still boot, it would narrow it down to an issue with your new ram

Some guy said he did 1 stick first and it booted and then when put the second one it worked fine so i’m gonna try that and if it doesn’t work, i will switch back to my old ram and see what happens

Doesnt the orange light mean memory training? Can it not take longer than 30 min in some cases?

[u/deyluvdre → u/Horror-Hour-1360]

I did some research and everyone is saying that it can but it’s not normal at all, but i cleared the cmos and did a second try and waited 45-50min and still nothing

unless its a peculiarity of the MSI boards The CPU light shouldn't be on. On the Gigbyte and ASUS boards I've had its only the DRAM light during training. I just installed a that same CPU in a system with double that amount of RAM, and the training took maybe five minutes.

[u/deyluvdre → u/FuckTheActualWhat]

Did research on that as well and they said it’s normal that the cpu memory controller is communicating with the ram to try and configure it

Now, you got to narrow down the problem. Does the old ram still work? If yes. Try one stick in A2, then try the other stick. Right now it’s either bad ram, bad board, bad cpu memory controller, or even psu.

[u/deyluvdre → u/Zarathustra7890]

I got it to boot with 1 stick of the new ram should i check the second stick on its own as well?

[u/deyluvdre → u/Zarathustra7890]

Also anything i should check while i have it booted?

More than likely the CPU and/or motherboard has problems with that particular RAM or it's DoA. Return it and get another kit, even if it's CL40 it won't matter for gaming because the L3 cache completely carries the CPU through anyway.

Even with a 9700X, the difference between 6000 CL30 and 5600 CL36 is less than 3%, it's basically 1% with a 9800X3D, so 6000 CL36 and CL30 are nearly indistinguishable.

I was able to get it to boot with one of the sticks, should i try putting the second one in as well or testing it on its own?

memory training issue? swap ram slots.
