[SOLVED] Mix&Match Vengeance LPX & Pro RGB

[Razerhe11]

So I built a PC yesterday and had two different modules of 16GB Vengenace sticks laying around, the CL timings, frequency@watt is the same at 18-22-22-42 and 3600@1.35 I was wondering if I could use them both at the same time. Also the rams are running at 2666 by default and when I changed the frequency to 3600 the PC wouldn’t post, I’m on Aorus Pro Wi-Fi X570. Would like some help with both the cases.

Ram should be in 2nd and 4th slot from cpu for Xmp to work, these are the primary slots.

Ram are in sets to minimise compatibility issues but since they're running together looks to be fine for now and probably reason for Xmp defaulting to 2666 is because they're in 1st and 3rd slots.

The memory is already installed in 2nd and 4th slots respectively, i think it did not post because i did not enable XMP and tried to tinker with them manually. I will try enabling XMP and tell you the findings in a bit.
Thank you

Enabling XMP worked like a charm, both sticks are now running at 3600@1.35v and 18-22-22-42 CL. Have to see if it would have long time impact on performance. THANK YOU for the help.
Edit: can you recommend a good memory stress test to verify stability?

Intel burn test and custom test 20gb of ram for a few passes, take a few minutes. That'll guarantee stability.
