It's true many Zen 2 chips can push FCLK beyond high limits, yet achieving more than 1800 MHz isn't guaranteed. A value around 3600 offers a solid compromise—fast enough while avoiding complications in BIOS settings, making it ideal for users seeking reliable performance without extra hassle.
We seem to be going in loops. I'm not focused on RAM alone; it handles what RAM does naturally. The IMC can manage those rates smoothly without trouble. What I mean is the combined speed of CPU and RAM. Sure, you can achieve a 2:1 ratio, but that just means cutting communication speed in half. No matter how quick the RAM is, you're only getting half the real performance at that stage.
It relies on how quickly you can execute your script to bridge the gap.
I looked into this before purchasing any RAM. Honestly, the board model might not support the speeds listed for certain PC models. My Z270 Maximus IX Hero is an example—I see it claims compatibility up to 4133, but most boards won’t handle much higher than 3600. It’s a known issue with this model. I recommend verifying the reliable RAM speeds reported for that board before buying. This helps avoid frustration and confusion later when trying to match your RAM to its capabilities. Get the proven performance numbers so you don’t end up with an overpriced set that underperforms. Good luck!
I realized we can stay under 60ns using a 2k fclk. Note: I should have started earlier, but if you push it to around 2100 fclk and run the RAM at that speed you’ll likely hit the 60k+ range for reads and copies. I’m back to four sticks now so I can’t exceed 1900 right now. I need to tweak it a bit to reach that higher dual rank. One last adjustment: 4x8
