aw8=max fsb @340?

[son_of_liberty]

hi forumers, hi abit support,

i got a big problem with my aw8. my mb dont boot over fsb 340, also in uguru is a gab between setting fsb 340 and than fsb 342 (otherwise this setting is a 'one-step' (e.g. 335,336,337,338 and so on). so i cant go higher than 340 fsb, even with mch @ 1.7. i thinks its a bios prob, so i post it here.
i use bios 16 with my 631.

can somebody help?
