The "Relax OC" option doesn't change the memory timings you configure in the BIOS. Instead, it affects the IMC (Integrated Memory Controller) parameters—such as write recovery time and refresh cycle—that are built into the CPU itself to help manage data flow between the computer's main memory and the system. This adjustment can make the overall process smoother or easier for your specific setup.
Otherwise, doing this is significantly more challenging and usually leads to higher temperatures. However, with advanced cooling methods like liquid nitrogen, some systems can handle it (though it often means lowering the operating frequency, which reduces the effectiveness of the optimization).
These parameters are accessible through CPU-Z, but they aren't very useful for most users unless you're familiar with the technical details. Also, not every motherboard supports manual BIOS adjustments for IMC settings. My Gigabyte GA-Z170XP-SLI does support this, matching the same OC capabilities as more premium boards.
I checked CPU-Z and found it only displays frequency, voltage, CL, tRCD, tRP, and tRAS—without showing the IMC parameters. This is okay because I wouldn't need to change them anyway, and I'm unsure if any improvements would be possible.
I confirmed in CPU-Z that when "Relax OC" is enabled, I maintain the same memory frequency, DRAM voltage, and CL/tRCD/tRP/tRAS settings while achieving a cooler operating temperature.
The "Relax OC" setting doesn't alter the BIOS-defined memory timings you configure, but instead influences the IMC (Integrated Memory Controller) parameters—such as write recovery time and refresh cycle—that reside within the CPU itself. These adjustments help ease data handling between the processor and RAM under your own BIOS settings by modifying latencies, among other factors.
This approach is significantly more challenging, often leading to higher temperatures. However, with advanced cooling methods like liquid nitrogen, some systems can manage it—though this usually means lowering the operating frequency, which can undermine the overall optimization.
Understanding these nuances is crucial since they aren't immediately obvious. You'll need specific knowledge to change them effectively. CPU-Z displays these parameters but doesn't provide much practical value unless you're familiar with the process. Also, not every motherboard supports manual BIOS adjustments for IMC settings. My Gigabyte GA-Z170XP-SLI can do it, matching even high-end models like the Z170X-UD5.
I checked CPU-Z and found only frequency, voltage, CL, tRCD, tRP, and tRAS—no IMC details. That's okay; adjusting them is complex. I also confirmed in CPU-Z that keeping temperatures down by 10 degrees while maintaining the same settings with "Relax OC" works.
