3218C043 did 6,71ghz spi 32M
But we had alot of problems with cb and cbb, and alot of debug code 55 which meant demount and defrost
We benched on Asus V formula
Zozolio and Rosty from octeamdenmark lost more than 200mhz
Chip was 6400 Spi 32M stabel
now ist a struggle to run spi 1M at 6.2Ghz.
no cb or cbb, Higher temp did not help.
We tryèd Titan nano and mx-2 with same result
