En VideoCardz hablan de que RyZEN podria arrancar en frio sin errores incluso a -29°C. Estro mientras se muestran pruebas de RyZEN y enfriado con nitrogeno liquido. La prueba de OC fue realizada con una tarjeta mdre Biostar con chipseth X370 y enfirado por nitrogeno liquido.

AMD Ryzen – no cold bug?Speaking of Ryzen, we also have a very interesting piece of information from HardwareBattle. The following photographs allegedly show Ryzen CPU being tested with liquid nitrogen on X370 Racing GT7 motherboard. If you look closely at the photograph below, you will notice a yellow multimeter, which shows temperature reading of -29C. Since the monitor is displaying Windows logo, we can assume that the system is working, and therefore, the cold bug is not present on this platform.
In case you don’t know what this bug is. Cold bug is when CPU is unable to warm up fast enough to boot properly, which basically makes the whole platform unresponsive or operate at low performance. The cold bug occurs only at extremely low temperatures. It is also believed that this issue is more common on AMD CPUs. That’s why it was so important to get the first proof that Ryzen boots successfully at such a low temperature. Hopefully, this will result in more people trying to achieve higher frequencies with liquid nitrogen and breaking new records.
De igual manera sugieren que RyZEN podria venir con su propia herramienta para el OC, asi como era el AMD Overdrive [cpu y gpu] o el WattMan actual [gpu].

Since Lisa Su took over AMD, the company has invested a lot of time and resources into the development of its new software. The utility called Radeon Settings completely changed our perspective of Radeon drivers. Meanwhile, on the CPU front, manufacturers have total freedom by supplying their software, which usually unlocks custom features of each board, plus it enables overclocking. So it is really necessary to bring an official software for CPUs?
AMD Ryzen Master?AMD may be working on its own software for Ryzen, as revealed by the following screenshot from NAMEGT. Obviously, everything is blurred out, so we can’t read it, but the software looks awfully similar to Radeon Settings. The sliders appear to be responsible for per core overclocking (Core 1, Core 2 etc).
There are quite a few other settings below, which could be related to XFR (Extended Frequency Range) technology. This technology will automatically adjust frequency based on how efficient is the cooling solution, which sounds similar to how Boost works on Radeon cards.
There’s also the first screenshot of the CPU-Z with Ryzen CPU and Biostar X370 Racing GT7, but unfortunately, this part is blurred as well, with the only visible part being AMD logo and core/thread count displayed as 8 and 16.
It appears that the sample used by NAMEGT is not directly from AMD. As it turns out AMD will supply Ryzen CPUs and motherboards at a special event called Ryzen Day, which will take place “in few days”, but this event is only for certain reviewers
