AMD Ryzen memory optimisation trick

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 Quote

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

No no, I understand dude. I was just pointing it out, not to put it in your face or anything though.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.

MB: ASRock AB350M Pro4, BIOS v2.5 (AGESA 1.0.0.6)
Ram: Corsair LPX 2x8GB 3200MHz C16 (CMK16GX4M2C3200C16S)
Timings: 16-18-18-36-54-1 (tCAS-tRC-tRP-tRAS-tCS-tCR)

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

Well that is certainly a positive thing to hear, one of the main points for this is to raise awareness and get a potential fix in future BIOS' if possible. I do remember the Taichi having the issue at launch, so this is likely a recent development.

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