But in your case go up a small amount and rerun orthos...

My cpu
3420 (9x380) on RD600...1.4625 bios but 3508(9x 390) need 1.51875....kinda lot of vcore for 90mhz

SHould i leave my vFSB and vMCH/ICH as it is now? What's the typical range of vFSB and vMCh for you guys?

Just tried vcore = 1.3750, vfsb = 1.325, vmch = 1.575
Results: Orthos small blend = failed after 54 mins, OCCT = stable, XP = stable, super pi = stable
