New RAM causing crashes, errors and boot loop

[Raichu]

 

I got a new RAM kit to add to my build. I currently have 2x8gb Trident Z DDR4 3200Mhz. The ones I bought are Klevv Cras X 2x8gb DDR4 same speed, same CAS Latency, timings, voltage etc. My mobo is ROG Strix B450 F Gaming. In theory it shouldn't be an issue adding this to my build, but after doing so I started getting file corruption errors, GPU errors causing crashes (Uninstalled and reinstalled drivers which seemed to fix this) Windows memory diagnostic tool shows there's hardware issues but does not specify more than that. Then my PC was crashing due to windows errors stemming from my M.2 drive, scan came up with issues, attempted a repair and this put me in a boot loop. Took out the new RAM, rescanned everything and redid diagnostics and everything's normal now, storage is healthy, memory diagnostic is normal, so pretty sure source of the problems was the new RAM.

 

 

What do I have to do in order to fix this weird issue when using this new RAM? Do I need to update BIOS? Or is it for some reason not compatible with my MOBO?

What's your CPU? 4 sticks of RAM are harder to run for the CPU's memory controller, so you might need to reduce speed below 3200 MT/s

 

Even when all listed specs are the same, there can be differences between RAM stick ICs that make them incompatible. That's why its usually best to buy a matched set. Or sell what you have and buy 2x16 instead.

CPU is Ryzen 7 3700x. With how RAM prices are at the moment I really wanted to save a few $$ where I can. If I can't solve this problem I'll return these and see if I can find 2x16gb that won't hurt the wallet too much.

If you haven't already, try the new sticks on their own. If everything works, try all four, with XMP disabled. If that also works that would be a good indicator the CP'Us IMC doesn't like this combination at (full) overclocked speeds.

 

If you're not on the latest BIOS, updating it would also be a good idea. Newer versions often improve memory compatibility. But if the issue is caused by incompatibilities between the sticks it might not help much.

New RAM on its own shows no errors. I'm going to try all 4 and placing them A1/A2, B1/B2 with XMP off. Thank you for your help

Put the matching sticks in the same channel as you said and try first without docp just 2133 stock. It'll be slow but that way we can see if they want to work together. 

 

Same timings and speeds can still be different brand of chips on the RAM and the sub timings might become a problem or the CPU just doesn't wanna run 4 sticks at 3200 without manual tuning of voltages / timings. That is a thing with Ryzen 3000.

I placed same RAM brand together, disabled DOCP and updated BIOS. Everything was working smoothly so I went back and enabled DOCP. Not sure what fixed the issue, but I'm not having any problems anymore. Thank you!!
