4 units of RAM Zen4 chipset
Hi! I own a workstation with these specifications: Ryzen 9 7950x, 64GB DDR5 RAM (two 16GB kits), Aorus 5200 motherboard, ASUS ROG x670e hero BIOS version 0805 from November 15, 2022, a Seagate Firecuda 530 SSD, and Windows 10 Pro. I’m not very experienced with RAM issues, but I’m having constant BSODs when using DOCP or DOCP 2 at 5200MHz. The auto config sets it to 3600MHz, which is more stable. I’ve heard about single-rank and dual-rank configurations, but I’m unsure. With dual-rank the speed cap is around 3600MHz. Should I: A) adjust settings myself, B) stick with 3600MHz despite the limitation, C) replace the 5200MHz sticks with better ones? Let me know your thoughts! Thanks, Sebastian.
The performance with four DIMMs is capped at 3600MT/s unless dual-rank modules are used, after which the Ryzen memory controller usually reaches similar speeds (around 6000–6400MT/s). However, it’s more likely the problem lies not in the number of sticks but in the XMP profile compatibility. Many motherboards misinterpret XMP settings across different brands, so manually adjusting frequency, timings, and voltage might be necessary. If you notice mismatched manufacturers on your sticks, consider swapping them for a uniform configuration.
It seems you believe two sticks work better across most systems, with exceptions on certain servers or high-end hardware.
Absolutely, it's true. DDR5 is a game-changer, especially when it comes to performance. But there are exceptions—like DDR3 and older platforms where the speed limits kept things simple. On DDR4 and particularly DDR5, having more DIMM slots can actually become a limitation rather than an advantage, unless everything is perfectly standardized. Generally, 2x32GB setups tend to work smoother than 4x16GB configurations.
Yes, fewer sticks mean fewer issues. The Ryzen DDR5 setup is still emerging, so it’s no surprise they’re facing some challenges. I recall the first-gen Ryzen had significant memory controller issues, which turned the "QVL list" into a hot topic on tech discussions.
Absolutely! Your Micron chipsets are all set. I believe adjusting the timings manually could help achieve stable performance around 5200 MHz. The AIDA64 stability tests seem suitable for this purpose.
Thanks for your feedback. I realize I might not have handled things correctly or fully understood everything. After reviewing the Thaiphoon reports and digging around, I noticed discrepancies in the XPM settings across both memory modules (it appears AMD translates XPM with DOCP). It seems the RAM might not be installed properly. Most values matched what Thaiphoon mentioned, but the TRW and TRD values varied between banks/channels. I set both channels to the values Thaiphoon provided, and it worked smoothly at 5200Mt/s so far—no issues detected. I ran Memtest86 and AIDA64 for over an hour each, though full tests usually take several hours, so I plan to try them tonight. Appreciate your support!
