Johnny Bravo,

Now that SetFSB supports the 4coredual RTM866-890 PLL, a 350 FSB is maybe possible??

Yes it is possible jimmor. Here's the proof :

345



350



355





Here's the cpu-z validation so that everyone can see that's not a photoshop job

Used pencil mod. Vtt - 0,68KOhm and Vagp - 1.4KOhm, i prefere to measure right in the resistors.

I thank you all for this because without you guys i couldn't do it
