The first of our OC guides is now live. This one is aimed primarily at extreme overclocking, but has some good info for normal usage, too. Expectations for overclocking frequencies and voltage requirements are all defined, as well as handy hints for troubleshooting via motherboard POST codes. A worthy read:

A normal overclocking guide may follow at a later date - assuming there is something of merit to write about. CPU overclocking is limited by the architecture itself. Unless yields improve, 4GHz is the expected frequency for most samples. Memory overclocking is limited by AMD's firmware.

Be sensible when purchasing a memory kit for the platform. Stick with kits rated below DDR4-3000, and bear in mind that kits binned on Intel platforms may not achieve their rated timings and frequency on the AMD platform.

Interesting. Yeah, there's some useful stuff in there for normal OCs.

Also, found a typo for the next update. The "ambient max" for "1.8V PLL Voltage" is listed as "Up to 1.4V", while the recommended is 1.8V.

Thank you , Raja!

May we have clarification on this:
"Max CPU temperature before throttling is 95 °C. This means the Tctl temperature which reports the highest recorded value from sensors on the die."

Gamers Nexus said the chip auto-throttles at 75°C ("This first chart shows two things, primarily: We’re looking at CPU junction temperature in blue and averaged core frequency in red during a Prime workload. Ideally, the red line is perfectly flat when under heavy load, indicating a more stable core clock. The blue line should never exceed 75C, as that is AMD’s maximum junction temperature for the 1800X – or TjMax." - http://www.gamersnexus.net/hwreviews/2822-amd-ryzen-r7-1800x-review-premiere-blender-fps-benchmarks/page-4 )

Also is 1.40V-1.45V recommended max voltage from AMD?

Has anyone gotten past 4GHZ on manual with a higher vcore?

They seem to be looking at the motherboard temperature sensor which is not the reference for CPU throttling. Use for example HWInfo64 and check the Tctl temperature reading, it's equivalent to CPU Package temperature on Intel.
