Issues with Corsair CMU32GX4M2C3200C16B on Ryzen 1800x
Hi everyone,
I purchased a new PC a while back and didn't adjust the RAM much because the Ryzen was still new, expecting some compatibility problems. After waiting a few months, I updated the BIOS to the latest version. Now I'm trying to push my RAM to its rated speed, but it's not reaching anything above 2133.
Specs:
Gigabyte Aorus x370 Gaming K5
Ryzen 1800x
Corsair CMU32GX4M2C3200C16B. Checked HWinfo and it's a Samsung chip.
There are numerous Samsung chips available. Which one could truly make a difference? Ryzen generally prefers Samsung B die ICs. The D and other Samsung components are either reliable or unreliable. Compatibility has improved significantly. This includes Vengeance memory, which I've noticed many Ryzen systems don't support well. Those are typically the lower-end enthusiast models from Corsair. Ryzen usually opts for memory brands such as G.Skill Trident Z, Flare-X, or Corsair Dominator, though some of these have also caused issues.
There are ways to address this issue in most cases. Often it comes down to configuration problems since many modules were designed with specific profiles in mind.

Ryzen usually leans toward memory options such as G.Skill Trident Z, Flare-X, or Corsair Dominator modules. Even these have occasionally caused problems.
There are ways to work around these limitations in most cases. Often the issue stems from configuration mismatches, since many of these modules were designed for Intel systems. This situation is gradually changing, but it's still relevant.
You might need to adjust the primary timings and voltage manually using the Ryzen calculator.

You may find that slightly increasing the memory voltage in small steps—starting with .005v increments—is necessary to achieve the desired timing or performance. I'm not certain about specific motherboard requirements, but generally, try .005v changes. Many Gigabyte boards restrict voltage adjustments to smaller increments than .020v, so use only the + and - buttons in the memory voltage settings if you make any modifications.
If you're aiming for reliable performance right out of the box, consider doing some research here:

Additionally, it's common that users have needed to overclock the CPU slightly to let memory operate at its rated speed, especially if the JEDEC SPD value is much higher than what the motherboard supports.
I believe you'll be fortunate if these modules can run smoothly at 2666mhz without requiring a CPU overclock. Running them above 3000mhz might not be feasible even with an overclock, but it's definitely worth attempting if stability and speed are priorities. Make sure to verify stability thoroughly using Memtest86 for at least two full tests, followed by an 8-hour Prime95 run (version 26.6 only). This step is crucial to avoid micro-errors in your file system.
