Good afternoon, I have a ProArt X670E Creator WiFi motherboard, an AMD Ryzen 9 7950x3d processor and two G-Skill Trident Z5 Neo RGB 16GB DDR5 memory modules at 6000MHz. I have decided to purchase 2 new identical modules for a total of 64GB of RAM. However, although in the BIOS it detects the 4 modules, when Windows starts it produces a blue screen and in that moment the computer restarts and I can't restart it anymore. On the board the orange led stays on and I can not boot if I do not remove the two extra memory modules. I have tried to swap the modules but the result is the same when I use the 4 slots.
Is there any way I can use those 4 modules or should I limit myself to use only 2?
Solved! Go to Solution.

Hello Javi_Montanes
It's not recommended to combine memory kits, doing so will cause instability or system failure.
Always purchase a single memory kit of the speed and capacity you want.

Wow, I didn't know that using the exact same model could influence combining two different kits! After trying different combinations and quite a bit of frustration on the modules I have managed to get all 4 modules working. It seems there were several problems:
- On the one hand I had to disable in the BIOS the AMD Expo, and lower the speed from 6000 to 3600 Mhz, apparently, the AMD processor is not able to work with 4 memory modules at higher speed than that.
- On the other hand, it seems that in some windows cache still identified the computer as if it had 32Gb and it seems that's why windows crashes.
- And finally what you say, when using different kits to the bios it is difficult to recognize the 4 modules as equal until the CMOS is not cleaned.
A mixture of problems that were making each boot was virtually random, but now it seems that everything works stably. I have rebooted the computer several times and it boots up quickly and without any problems.
I hope it continues to do so.
I also found this video very interesting to understand all these problems in AM5: https://youtu.be/P58VqVvDjxo?si=OvN6BIJb0lXpT-hZ
