DDR4 tRFC effects on avg., 1%low and 0.1% low FPS @ 3200Mhz. and Ashes of the Singularity

[80251]

I'm amazed that this ONE timing metric can make this much diff. in 0.1% lows:

Of course this is only in one game.

Here's the article: https://www.gamersnexus.net/guides/3333-memory-timings-defined-cas-latency-trcd-trp-tras

Technically they all are important lol.

288 tRFC here, think I am good.

The old "only primary timings matter" is dated.

I agree... trfc is one of the top timings that really affect performance, sometimes even more than frequency.

I run mine as low I can... 254

I am at 255 for Trfc, I can go lower, my Royals are ok with it, but the Black and Whites are not.

3200 flat 12s felt a little snappier than flat 14s.. but that could be all in my head.

I am not sure how you can set uneven numbers for that, as it has to have trfc/2 and trfc/4. I guess it auto adjusts to some other values in reality.

You can set it to whatever you want, there are a ton of registers that are not available to us.

I've noticed that in Asrock's Timing Configurator there are a dozen values listed (at least in the old version) that can't even be seen in the BIOS settings.

Why do they hide them though?

Depends on the motherboard. Higher tier ones generally has them all.

What is the second and third tRFC value? in your graph.

Here is mine
