AMD Ryzen memory optimisation - The effect of tRC timings
Cinebench R15

Cinebench R15
Moving onto our first true benchmark utility, Cinebench R15, we were able to see no real improvements to our CPU's multi-threaded and single-threaded scores, performance changes that are easily within a margin of error.
The noteworthy performance change in the OpenGL test, which had has a notable boost in rendered frames per second when our enhanced tRC timings were used. Even so, these boosts are relatively minor.

I like it how the test rig specs in the box say "1080 Founders Edition", although the picture of the PC under it shows and ASUS Strix card

That is the thing with test beds, hardware changes all the time. I can't take pics with every hardware configuration.

A new update was just released today for AGESA 1.0.0.6a, so I'll need to see how that impacts things, but in this one case at least, things appear to not wonky.Quote
For whatever it's worth, my memory/motherboard does not seem to exhibit this issue. My XMP 2.0 values populated and booted without any fussing, and the tCR value is accurate.

Hopefully other manufacturers will soon follow suit. It is memory performance that is simply sitting on the table.Quote
