my MB supports up to 1333FSB CPU's, do you think that getting 3.3-3.4Ghz will be hard on my current MB? i don't want to upgrade to a EP43 or EP45 if that is possible

Bump the multiple down on your E5300 and see if your board can run 400FSB stable. If so, you might have a chance.

my FSB can't go higher than 343FSB but maybe its a CPU wall and not a chipset wall, what do you think?

You say it can't go above 343mhz FSB, but is that with the multiplier up? If you did for example, 400x6=2.4ghz that would be below stock so the vcore needed would be stock or even a little less. You would more than likely need to increase the NB voltage and maybe the VTT a little.

Change it to a lower number, like 7 or 8.

its 343 @ 6x multiplier but i never tried to raise the VTT or NB voltage

You'll have to raise the NB.

I don't know if your power supply would be able to handle an overclocked q9550. I would just save your money. Your motherboard/psu is going to limit the OC of any processor.

No NB control in my MB, only VTT control

 

[ChickenInferno]

you should. It might be called MCH voltage.

yes i found it and raised both the MCH and VTT to 1.4 but no luck getting past 343FSB...maybe its a CPU FSB wall and not a MB FSB wall?

 

[ChickenInferno]

That's very likely. Most motherboards can do 1600mhz fsb either standard or as a pretty easily obtainable. Speed.

I have a P35 chipset & can go up to 480FSB.

You should be able to reach 4GHz easy.

 

[omari79]

thanks guys...i will give a quad core (6600 or 9550) a try then

 

[2thAche]

I know the G41 chipsets have a wall at around 340FSB. Maybe true for your P41?

 

[omari79]

will i will buy a quad core anyway, if my current MB can go 400FSB+ then i will leave it, it not i will just buy a GA-EP45-UD3L/R and be done with it
