Hands down the best technical article on Ryzen I've read so far. Check it out here: https://forums.anandtech.com/threads/ryzen-strictly-technical.2500572/ Some quotes: - "Zeppelin features a highly advanced power management, as stated many times before. Just like Carrizo / Bristol Ridge, which feature a very similar PM, Zeppelin can infact support cTDP as well. cTDP is not officially supported (or available) on any consumer Zeppelin based SKU (AFAIK). The lack of official support is merely a distraction. 850 points in Cinebench 15 at 30W is quite telling. Or not telling, but absolutely massive. Zeppelin can reach absolutely monstrous and unseen levels of efficiency, as long as it operates within its ideal frequency range." - "Overclocking Ryzen, at least the higher-end models is kind of a double-edged sword. Due to how the Turbo / XFR operates in Zeppelin and the rather slim overclocking margins, the user might end up actually losing single core performance when the CPU is overclocked. Since the Turbo / XFR will always be disabled when the CPU is overclocked (upon entering the “OC-Modeâ€), the single core performance might actually be lower than at stock, if the user is unable to reach the same speed on all cores as the CPU operated at single core stress at default (e.g. 4.1GHz on 1800X SKU)." - "As indicated by the Vmin-Fmax curve, Zeppelin's voltage scaling is perfectly linear until 3.3GHz (25mV per 100MHz). The first deviation ("Critical 1") from this linear behavior can be seen at 3.3GHz. The second and the final deviation ("Critical 2") can be seen at 3.5GHz. Beyond this point the voltage scaling is neither linear or recovers even temporarily, and the CPU is requiring higher voltage in increasingly larger steps to scale further. The ideal frequency range for the process or the design (as a whole) appears to be 2.1 - 3.3GHz (25mV per 100MHz). Above this region (>= 3.3GHz) the voltage scaling gradually deteriorates to 40 - 100mV+ per 100MHz."

Was told this issue will be fixed in a new AGESA code. In other words: it was an AMD issue, not C6H issue. Thanks for finding this bug @Mysticial!

Quickly tested here too, failed on both systems (changed memory). Also failed with higher SOC voltage.

Hmm, what BIOS/AGESA?

Stickied

Sneaky submissions, good to see you're still alive Sami!

Nice!

Not really. I only spent a couple of hours with the platform under LN2, so I was mainly focused on getting an idea of how to get the clocks up. More testing soon ...

Currently not working (and I don't think there will be any support for it)

Here's an even sadder fail (but with better memory)

Couldn't finish before my session was over

Just an ES from the stack I think. AFAIK, ES is a bit stronger than retail at the moment, but as always this will improve over the next weeks/months. IMO 1700 non-X is the way to go ... 8c16t at 320usd is hard to beat

Excellent guide!

Will do with retail part some time next month

Sweet! What's next cooling?

Nice! Day Zero purchase?

Need to check if that one is still active actually

"Real world" is a difficult topic. Would you say X265 transcoding is real world?

Fixed

Price-wise it would probably be very similar to the existing OBT as the main restriction is on volume. Any costs we could save on material because of the size would be offset by lower production volume.

Hi everyone! We had some requests regarding a mini version of the Open Benchtable. The designers got to work and came up with a design that is significantly smaller than the original benchtable. It uses the same pushpins, thumbscrews and brackets so it's backwards compatible. It only supports SFX power supplies and mini ITX motherboards to make it as compact as possible. Currently this is just a proof of concept. Depending on the interest, we can consider doing a small production run. Let us know what you think! --------- Update June 2017 The prototype V1.0 is officially announced : A new Mini member of the family : OBT Mini --------- Update July 2017 As of now the prototype is 802Grams -------- Update July 2017 The 3 colors of the OBT

@Mysticial send me an email with instructions what you need to get Y-cruncher ready for Zen

Just to add/highlight some context. This is previous best Cinebench R15 for AMD consumer CPU: Niuulh`s Cinebench - R15 score: 1218 cb with a FX-9590 1229 with FX-9590 at 7679 MHz 2449 with Ryzen 7 1800X at 5200-ish MHz :celebration:
