Did I buy not working DDR4 memory? Unable to use XMP profiles

[KristijonasG]

Hey guys,

I recently decided to upgrade my system, so I bought motherboard, memory, m.2 nvme ssd and used cpu. 

Everything seems to be working well, but I can't enable XMP on my new memory. Everytime I play with the frequencies or timings I get blue screen or memory errors.

My hardware:
CPU: Ryzen 3900XT (Used)
RAM: Corsair Vengeance LPX Black DDR4-RAM 3600 MHz 2x 16 GB 64GB in total (Brand new)
Motherboard: MSI MEG B550 UNIFY Gaming Motherboard ATX-AMD AM4 Ryzen 5000 Ready (Brand new)
SSD: Sabrent 2TB Rocket NVMe PCIe M.2 2280 Internal SSD (Brand new)
GPU: MSI ARMOR GTX 1060 (From old system)
PSU: Corsair RM750 (From old system)
Cooler: AIO Corsair H100i V2 (From old system)

Things I tried to fix this problem:

• Update BIOS. Tried 2 different BIOS versions.
• Tried to use XMP1 and XMP2 profiles. 
• Tried to manualy tune the memory using DRAM calculator. System didn't boot after that, had to use CMOS
• Tried to lower the frequency, I could boot at 3200Mhz but the system wasn't stable. Memtest showed some errors.

Is it normal that XMP profiles doesn't work? Do I need to buy better memory or is it my motherboard causing all those problems? 

Thanks for your help!

could i see the cpuz memory and are they in the right slots?

Here you go: 

I have 4x16gb so all the slots are filled

XMP is not guaranteed to work - it is an overclock. Your particular CPU may need some more voltage tweaking to get things to run stable. I am not as familiar with AMD, but for Intel you would usually adjust the VCCIO and VCCSA (System Agent) voltages to get faster RAM to work.

well if there 2 2X16 they might not be compatible so i might just try 2 sticks and i would try the stock timings you could try switching the slots there in if they end up not compatible just to see

Vengeance LPX and Ryzen have some odd behaviors.

2866mhz, 1.37v, 16-18-18-36 timings. These are the stable realistic max for LPX with Ryzen 3000 and below. 

(spent a whioe day dialing in these settings and reinstalling corrupted windows after failed attempts)

Thanks man! Do you know which memory would work better? I can still return LPX and grab different memory kit

[BiotechBen]

LPX uses Samsung E-dies, Ryzen tends to like Samsung B-dies. Honestly, go with a kit of Crucial Ballistix 3200. The latency is going to be what gets you more noticeable results. Ryzen 3000 is going to hit snags north of 3200, really depends on the memory controller for stability.

Purchased Corsair Vengeance RGB PRO SL 32GB (2x16GB) DDR4 3600MHz C18 and XMP works now! Thanks guys
