whats better when ocing?
 
bumping up the multiplier and keeping fsb low?
or bumping up the fsb and keeping multiplier low?

I seem to get better memory intensive benchmark results from the highest FSB my hardware will support so my vote is "lower multi + higher FSB".

The only benefit of running at a high FSB with a lower multiplier is in synthetic benchmarks but running your Ram strapped at 400 with tighter timing, seems to echo in relevance.

Give it a try and let us know:)

okay so theoretically...3800\6 =633.33 * 4 = 2536 "fsb"
so i did 634 *6 = 3.8ghz around.

wt lol i tried that, bumped up vcore to 1.3v just to be safe and will lower later, and somehow it jumped itself to 4.09ghz?
and cpu multiplier was 9 which doesn't make sense? cause 634* 9 = like...5ghz
wtf???

is cpuz messing with me? -_- keeps giving me diff things....could this be because of intel's speedstepp?

Yes, speedstep needs to be disabled for accurate overclocking. (C1 + EIST? ).

What board/cpu are you using? 600+ FSB is pretty far out there..... :)

asus striker II formula. E8400 C2D c0 stepping. and just in case, using ocz reaper hpc 8500 1066mhz 4gb ram

okay changed fsb to 507.x7.5 @1.2vcore
successful boot, turned off intel speedstep, opened realtemps, my temps are great.
but in cpu-z, core voltage reads 1.104V-1.088V (changes), and core speed changes from 3041.2@ x 6 to 3801.6@ x7.5 ....so it switches..good?bad?

btw, my ram sets is supposed to be pc2-8500 but cpu-z reading 6400...??? how do i change that?
