This is the completed form of Radeon-V which standed Radeon-Virtualized.
This build is called Radeon-eXtended Virtualization. Made for Virtualization and other heavy core usage workloads
Let me start with the specs.
4x Opteron 6276 @ 3GHz OC
256GB of DDR3-1066MHz RAM.
4x Dynatron A13/R27 Cooler
2x R9 Fury X Crossfire
480GB Sandisk Ultra II
Modified Rosewill RISE Case
Previous Radeon-V build could only hit 2.8GHz maximum (2.7GHz maximum with Virtualization on) with that airflow configuration, and frankly it was way too loud for normal usage.
So I got bigger 3U coolers intended for workstations and upped memory from measly 64GB to 256GB of DDR3. and rearranged Fury X radiators so that hot air would escape the system at much faster rate.
This allowed me to break through 3GHz barrier with Virtualization on, which was not possible.
It is fully stable after 10 hour torture loop and CPU-Z validation - https://valid.x86.fr/i811gx
I broke World record for the highest non-ES Quad Opteron 6276 with all of its memory channels loaded with High density Quad Rank 16GB modules, clocking from base of 2.3GHz to 3GHz on all 64 cores. Basically 30% Frequency increase across all cores.
I still feel that these Opterons have headroom left, so I will try and hit 3.1-3.2GHz in following weeks
