Configuration for a 4x16 DDR4 RAM at 3600MHz
Configuration for a 4x16 DDR4 RAM at 3600MHz
Here’s a simplified version of your notes:
You’re using a Ryzen 5 5600G with an ASUS Prime B550 Plus BIOS updated to version 4x16 DDR4 Trident Z Neo F4-3600C-64 GTX. After adjusting the BIOS and using AI Tweaker, you enabled DOCP at 3600MHz. The system only runs at 3200MHz, showing a higher voltage than expected. You’re wondering if your motherboard supports this speed, or if the memory controller is limiting it. Your friend with similar RAM managed to run at 3600MHz using an XMP-enabled card. If you’re not comfortable changing things, accepting 3200MHz might be the safest option. Let me know if you need more clarity!
Experiencing 4 dimm at the top end of the frequency range isn't a straightforward setup. In my R5 3600 home server I had 4x32G DDR4 dimms running at 3800mhz, but they wouldn't function beyond 2400mhz if I attempted XMP profiles or auto-timing adjustments. The best approach to begin manually tuning is using the Ryzen Dram Calculator.
The CPU is officially limited to 3200 MT/s. Exceeding that is considered an overclock. XMP/DOCP/EXPO functions as a profile enabling the BIOS to boost RAM speeds using settings verified by the manufacturer on their hardware. Still, an overclock isn't always reliable. With more RAM modules, the memory controller must handle increased load, which can lower the likelihood of success right out of the box. It's likely XMP will perform adequately with two sticks, but four may need further adjustments.
I'll take a closer look and see if I can help it function properly on my own.
