Looks like 3.7 GHz is the sweet spot for 1700, at least for this batch.
With almost the same performance for $200 USD cheaper than 1800X, it kind of renders 1700X/1800X meaningless to get given how l ...

Yep, kinda glad I didn't get 1700X, esp. after verifying that the power saving states still being functional (7 cores idling at 1.x Ghz) when I am just redditing.

If you gonna build soon and OC, be aware of the fact that not all BIOS currently offers options to edit P-states. For example, ASUS C6H offers it, but the ASUS B350 board offer just a constant FID, DID and Vcore. IOW the core would not drop to lower clocks when idling.

OC done in Ryzen Master does not suffer from the issue, but it doesn't seem to persist after sleep or reboot.

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

Gonna stick with 2400 for a while.

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:

~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?

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

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 generat ...

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