I thought I'd have a bit of fun & flog a Celeron D347 on a GA-EP35-DS3 mobo under DICE but with dissappointing results. I've hit an FSB wall at 201.
It'll run SPi1M at 201*23 (4623MHz) with Vcore=1.35v.


No amount of increase in volts will allow a boot to windows at FSB=202 or greater.
I've booted to windows with extreme settings of Vcore=1.800v, MCHv=+0.3v, FSBv=+0.3v & FSB=201 & can run SPi4M with a max CPU temp= -49deg.
As soon as I set FSB=202; no boot.
I thought maybe a NB strapping issue, so I tried booting at FSB's of 210,220,......300 still with no success.
I can boot at 201 then increase FSB up to ~260 in windows using Gigabyte's Easytune.


This is the same mobo', RAM, PSU & cooling combo' that went 596FSB with an E8400 so I'm a little stumped.
Surely if the CPU will do 201FSB with a very small Vcore bump it should be capable of booting at much higher with more volts.
What piece of simplicity am I missing here
Help pls,

IIRC, older stepping ones had very low FSB ???? try another motherboard ?

I'll have a DS3P on Sunday (no more Dice till Monday) to play with; may help.
If not, maybe a 965 chipset? When I see people hitting ~8gig with these CPU's @ 'hwbot' I thought 7gig shouldn't be toooooo hard.
I should know better by now.
I've got a litle Dice left so I might punch the Vcore to 2.0v & see if I can get any higher OC with ET; or a dead mobo'

I'll shoot for some more points for the 'i4memory' team (& personal satisfaction of course)

Cheers,
Ruffy.
