Problem occurs when restarting after adjusting RAM frequency to 3600mhz
Started with 16 GB of RAM and it worked fine at 3600 MHz, but now with 32 GB it only boots at 2133 MHz. Everything else looks identical. I’ve tried different speeds and even reached 3200 MHz without success. I’m having trouble getting it to start. I need to keep updating the BIOS and clearing it to make it reboot. The motherboard uses an Asus AM4 socket.
Check if you're employing XMP/DOCP or adjusting the frequency yourself. Also, confirm whether you're modifying the DRAM voltage.
Not familiar with XMP or DOCP settings. The BIOS manual doesn’t list a voltage adjustment option. The shift from 16GB to 3600MHz didn’t require a voltage change, so the system likely handled it automatically. With 32GB storage, the need for such adjustments might be less critical now.
I noticed you're asking about the specific Corsair RAM used for four DIMMs with speeds around 3600MHz. Running them all at maximum XMP (ASUS calls it DOCP) isn't always straightforward because signal interference between RAM and CPU can affect performance, leading to a default speed of 2133MHz instead of the typical 3200MHz. You might try adjusting the BIOS DOCP settings, but results aren't guaranteed.
The specific RAM you possess isn't known. There isn't any DDR4 type available that is officially labeled for running at 3600 MHz without XMP/DOCP support. It seems your motherboard probably allows flexible memory settings, as 3600 MHz at 1.2V would likely trigger crashes or instability in most systems. I suspect the RAM was designed to work at a minimum of 1.3V, possibly around 1.35V. Using four sticks adds extra demand on both CPU and memory, often requiring slightly higher voltages for each component. Since CPU models vary widely, it's difficult to give a definitive answer. AMD’s official guidelines for Zen 3 and 4 single-channel modules state 2933, so if you manage to exceed that, your processor is performing well.
DCP/XMP also manages voltage; Ryzen 3 usually struggles with more than 3000MHz on four sticks, and the memory controller can't cope. Therefore set the clock manually at that frequency. For a 32GB configuration, consider replacing your setup with a 2x16 configuration (I run it at 3600 without issues).
I kept the same RAM model but changed its color settings, yet the system runs slower than expected.
It's a bit disappointing that overclocking remains limited, especially with DOCP. You're likely to reach around 3000MHz at best, and hitting 3200MHz would be rare. Most recommend sticking with just two DIMMs for better speed and stability. Four DIMMs are often seen as a good choice for PC displays at major events, but they can limit potential performance gains. If you really want 3600MHz, consider swapping your recent 2x8GB RAM for two 16GB units instead. The older 2x8GB option is still useful—keep it or sell it if needed.
