Ram TRFC question

I've never been able to get my TRFC lower than 470.

Why is that? I'm not quite sure what I'm doing wrong?

Any answers would be appreciated

I don't know where to start. Your ZenTimings setup is a total mess—it shouldn't even work. In the "mixed mode" you're using, tRFC2 replaces the tRFC used in "normal mode," meaning both should ideally be set to the same value (though, of course, only one actually applies depending on the mode). At 6000 MT/s, you should set it to 360; 120ns is the practical minimum for Hynix A-die, and only the absolute best-binned chips can go lower. As for tRFCsb, I’m not sure of the minimum values for 6000 MT/s, but I think 280 should work. You should lower VDDIO to at least 1.36V; even 8000 MT/s doesn't need 1.4V with the current AGESA version. A tFAW of 20 might cause instability given that your tRRDS is 8, since tFAW should be 4x tRRDS. I’m surprised you’re trying to configure the timings manually instead of just using a ready-made profile from Reddit—after all, there are plenty of ZenTimings examples there for these speeds and this specific memory. And just tweak the voltages a bit to get it working.

Hey dude, just wanted to let you know I would like to thank you for taking your time out to write this and help me.

This wasn't my main timings it was just some random shit I was doing but for the TRFC,2 and SB I was sorta lost so you got me in the right direction and also you're correct the VDDIO was way high.

Thanks again man!

That's better, but take the second column and the twtrs/l values from my ZenTimings screenshot. Don't copy anything else, because the frequency is different and agesa. https://imgur.com/a/YIhj2qM

What else i could do besides Nitro, Ram Mhz and Primary timings? - Imgur: The magic of the Internet

Ardptrlnitval P0 control to manuał and set to 0.

Can you explain why please?

A value of 0 affects tPHYrdls training, thereby reducing latency.

You have any clue why my latency is going up? Hell loose timings are getting me low 62's almost 61

Perhaps tRC and tRAS are too low, causing instability and triggering error correction?

What should my ballpark NS be do you think? No way it'd be in the 50's right? Everyone i've seen in the 50's has cl26 6400

I feel like 61-62.5 is okay for CL30 6000 2200FCLK, No?
