So AMD pust this link on their Facebook explain some finding of their own test

Finally, as part of AMDs ongoing development of the new AM4 platform, AMD will increase support for overclocked memory configurations with higher memory multipliers. We intend to issue updates to motherboard partners in May that will enable them, on whatever products they choose, to support speeds higher than the current DDR4-3200 limit without refclk adjustments.

Damn it .. now DDR4-3000 is not officially supported , I should have bought
DDR4-3200 when it was on sales :(

The blog also suggested use High Performance Power Profile with Windows 10 for optimal performance

Gonna stick with 2400 for a while.

It doesn't make a practical difference beyond 2666 MHz

My Ryzen tower is nice. But the attempt to dump macOS (?) severely ruined my daily workflow. For god's sake I can't even find a client which supports CalDAV and CardDAV properly while not sucking at UX and UI.


Hope that we will see P-state editing software soon (which auto-applies settings at launch/wake) from the community, though probably it will take some time since AMD hasn't even released a single developer manual for 17h.

Extremely insightful and detailed analysis on Ryzen's gaming performance:

In short, something is very funny with the core utilization;
Disabling 2 cores and all those CPU hungry games lost performance only marginally.

~11:05 is a big "told ya" moment for me. People around the Internet really enjoys the "inter-CCX is flawed" bandwagon while (understandably) not looking into the details. Could I blame clickbait journalism?

Got an exception for you: Guild Wars 2. Setting core affinity to half of the cores yields a considerable FPS drop (up to 50%), despite the game being known for CPU taxing and not scaling well (like any MMO).

Got stuck on 2667 with my 2400 2x 8GB kit + 1700 + ASUS B350M-A + 0509 BIOS even with way looser timings and way higher VDDQ/VTT. Anyway ~95% of stock 1800X (1600-1650) in Cinebench R15 is pretty impressive.


Edit: It seems that locking at full speed doesn't hurt the idle power consumption at all...

From what I know 2666 MHz for ram is the maximum unless you use ASUS's Crosshair;
this is a limitation of clock generation of the CPU or something, where ASUS's board has an independent clock generator for it.
I can be wrong though. Anyway 2666 MHz is very good already, no observable gaming difference can be seen beyond it baiscally, instead you may play with the CL timings.

Just another article justifying your choice:

IIRC External CLKGEN is for >3200 MHz, since AMD doesn't offer multipliers higher than 32x.

其實係咪用唔番am3果d heatsink

Many of the old ones can be used if a new kit is provided (Corsair and Noctua), check with the manufacturers.
