AMD Austin Tech Day – Phenom II Dry Ice / LN2 leaked info

AMD Phenom II processor leaked information and images have been making their rounds on the internet despite an NDA being in place.  Phenom II processor will be AMD’s 2nd 45nm part and it seems overclocking head room and scaling under the cold has dramatically been improved.

Our very own member, Josh Collins (moloko) and co-founder of abided by the NDA, but did provide some info as what went down on AMD’s Austin Tech Day in our forums.

The new platform from AMD will be called ‘Dragon‘ and will be focused around the new ‘Phenom II’ processors, 4800-series Radeon graphics cards and 7-series chipset based motherboards.

Phenom II and the Dragon platform can overclock to 4GHz on air – we were demonstrated a system @ 3.9GHz using stock bus frequency and HT link frequency and a multiplier set at 19.5x. This was done with 1.55v BIOS set. This system was looping endlessly through a Crysis time demo without issue; by the end of the day it was past 100 loops.

The platform core specifications demonstrated were as follows:

  • Phenom II processor
  • GIGABYTE GA-MA790GP-DS4H motherboard
  • Radeon HD4870X2 graphics
  • OCZ Reaper memory

While the unit demonstrated was @ 3.9GHz, we later had a hands on benching period with the new platform and I was able to quite easily reach this stated 4GHz frequency.

This same platform also exceeded 5GHz on liquid nitrogen cooling. But what was perhaps the coolest (no pun intended) specific of this demonstration was the processor operating and even cold booting at -196 degrees Celsius – that’s right, AMD has no cold bugs of any kind, at all for Phenom II!

During this LN2 session the system was demonstrated operating in excess of 5GHz and running 1.95v BIOS set (1.936v CPU-Z read in Windows) and as stated, at the maximum lowest temps available with liquid nitrogen – time to find a liquid helium supplier peeps!

Nevertheless, more Phenom II information was leaked as both PC Perspective and had more information to share.  AMD Phenom II launch plans list the following processors to be released including a AMD Phenom II X4 940 Black Edition.
