E4300 & E6300

[smsmasters]

E4300 1.8ghz 9x multiplier
E6300 1.86ghz 7x multiplier

So let's say I overclocked each cpu to 3.6ghz
E4300 1.8ghz (200mhz fsb stock)
400x9 = 3600mhz (400mhz x 4 = 1600mhz fsb)

E6300 1.86ghz (266mhz fsb stock)
514x7 = 3600mhz (514mhz x 4 = ~2056mhz fsb) This seems a bit unlikely to achieve due to the already high FSB


Will the E4300 be the better option for overclocking?

A lower multipler means the fsb can be set less and achieve higher overclocks, like I have calculated above? Am I correct?

It certainly looks that way. Your calculations are correct, you can get better clock with the same FSB on the E4300 (if the cpu itself allows it)

Another thing to bare in mind is that E4300 isnt a large cache chip to begin, with half the cache disabled. It should therefore be cooler, which means it should clock even better again.

Not true.

E4300's run hotter than 6 series chips and require more vcore for the same clocks

In my testing

Not really - only if:


A) You have an FSB limited motherboard (one that can't hit say the 500MHz that it would take to reach the practical limit of most E6300 CPUs).

OR

B) You have 'more basic' RAM and you don't want to run a divider.

OR

C) You can find the E4300 for a good deal cheaper than the E6300, as it should eventually end up being.



In any case bear in mind that most E6300s aren't going to be hitting 3.6GHz on air with any voltage you'll want to run 24/7 (some will though but 3.4-3.5GHz is a more realistic top-end, everyday stable target with decent air-cooling).
Even fewer E4300s are going to hit 3.6GHz with 3.2-3.4GHz being more likely (again at everyday voltage/stability etc).

Also it appears that clock-for-clock the E4300 is slightly slower than the other 2MB cache Conroes.
