my guess is the ram....try different kind.

i presume you checked that C1E and EIST is disabled.
Yep c1e and EIST disabled.

Trying a stick of Gskill now. Experienced same problems with Gskill to start with. FSB limited to 290. Obviously tried various dividers and what not.

Now out of the blue, I'm gradually climbing again. Currently at 320x9. Really don't know what the problem is.

Just wondering if I over did it expecting to be able to kick off with 420x9 immediately. Almost like something tripped out.

Hopefully I'm back en route.
