Overclock RAM without a documentation file
Overclock RAM without a documentation file
Hello everyone, I'm a newbie overclocking here. My ASUS 520M motherboard doesn't have the docp enable or overclocking features for the Ryzen 5600G. I adjusted the RAM speed from the default 2666 to 3000 and the system is running fine, showing 3000 in Task Manager. Is this safe and dependable? The RAM kit I'm using is GSKill Aegis 8GB with 2666x2. I haven't changed any BIOS settings. Can I push the frequency beyond 3000?
You can test 3200Mhz and check stability at 3200 CL16-18 for Ryzen. Go beyond if needed, but aim for a setting where it doesn’t bluescreen or become unstable. Adjust voltages if issues arise; the exact values depend on the RAM IC/DIE you use.
CL16 could be quite aggressive, possibly matching CL18 and copying timing settings from a comparable model if needed. Ryzen tends to be more sensitive to timing than Intel, so some lower timing XMP profiles may not work consistently. Still, a stable 3000 on a 5600g looks solid.
CL16 isn't entirely off the mark; a 3200MHz clock speed could range from CL14 to CL18 based on my observations. These APUs tend to be more sensitive to memory speeds and timing for stability, so opting for higher timings might be a safer choice. Running 3200MHz on these chips can be challenging. I've experimented with earlier generations like the FM2+ APUs and ended up choosing Ryzen 7000 models for my projects. It might become my media PC eventually. A great video to watch for @Morty77.
adjusting the memory frequency to 3600mhz is just a suggestion. you mentioned lacking knowledge about the motherboard, and the CPU Z reports a different frequency. I checked the timings and saw values like 26, 25, 25, 58, 83. I think you should halve them for more accurate results. The system feels stable, and games run smoothly enough. I’m not overclocking because it isn’t supported, and I didn’t change any voltage settings. How much more can a 2666 DDR4 kit handle? Also, what matters most for gaming timing is the actual clock speed, not just the numbers you see. I didn’t use the Vega GPU, I used a GTX 1660 Ti.
The Uncore clock could be a fabric clock or f-clock. It runs at the same frequency as the memory clock (m-clock) and synchronizes communication between CCDs, I/O dies, and the PCIe bus. The motherboard likely maintains a 1:1 relationship between f-clock and m-clock.
The motherboard adjusts voltage automatically to around 1.35V from the default 1.20V when memory speed changes. Most settings are fixed or auto, with few adjustable options. Running a 2666 at 1.20V rated for 3600Hz at 1.35V is likely safe, but verify your component specs and consult the manual for confirmation.
That's correct... with those settings you won't notice much improvement. Consult AIDA64 to verify the latency—check if it's stable or overclocked, and compare with your current settings. Timings and sub-timings matter more than you think. In short, measure the real latency for a better idea. For example, if your RAM is already overclocked to 3600 at 16-16-16, a latency of 14 would likely cut the delay by about 10ms. Probably isn't worth adjusting sub-timings unless you're okay with a lower frequency. Just experiment and test, especially for latency.
