AMD Ryzen memory optimisation - The effect of tRC timings

Geekbench

AMD Ryzen memory optimisation trick

Geekbench

In Geekbench we see a more noteworthy performance improvement than Cinebench, with boosts in single-core, multi-threaded and multi-core memory scores.  

These performance increases are not exactly transformative, especially when compared to the move from 2666Mhz to 3200MHz, but it is certainly a worthwhile boost when considering how easy it is to achieve.

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
