does FSB matter

[Maccer101]

Hi All,

I have a few Noob Questions regarding my first build and OC

First off my system and settings

E2180 using OCZ Vendetta
GA-P31-DS3L
2x1gb Corsair PC6400 4-4-4-12

Running Ubuntu 8.04 so limited for OC testing software

Currently running E2180 at 333x9 = 3ghz

Manual voltages
RAM +0.3v (as per Corsair reccomendation for 4-4-4-12)
PCIe Normal
FSB +0.1v
GMCH +0.1v
GTLREF Default 0.63xxxx
CPU 1.45v

Question 1 In theory is 333x9 better than 300x10 overall due to having a higher FSB and CPU Clock:RAM? or is 3ghz always 3ghz?

Question 2 What is GTLREF voltage control ratio? Its not shown in the mobo manual as a choice, but its there in my BIOS, it
is set at the default and the other choices are lower values.

Question 3 Are these voltage settings okay, I know the CPU one will vary from chip to chip but do I need to apply over-volting to FSB & GMCH for this level OC?

Thanks

300x10 would most likely mean that your cpu will run cooler than 333x9, but first you have to make sure your cpu has an unlocked multiplier

looks good

I can run it at 6-10 multiplier from the BIOS (and confirmed in POST), 333x9 idles at 31c according to my Gnome Appelet

I did a few tests and found that a lower fsb/higher multi combination was faster by a miniscule degree, mainly owing to the tigher RAM timings I could use.
Also, as said by others, lower fsb=lower stress.
