Overclocking E4300 with Abit IP35

[[TW]Fox]

Hi guys,

I was previously running my Gigabyte DS3 and my E4300 at 330Mhz FSB, giving me 3Ghz. This was fine. I've got OCZ Platinum XTC whatever memory that's rated 800Mhz. Becuase of this, I used the 2.66 option in the memory section of the DS3 so that my memory didn't run at FSB speed (As that would give me 1320Mhz, far too much), instead it ran at something like 878Mhz.

I now understand that this may not be possible with the IP35. Is this true?

Does this mean I'm now pretty much screwed with regards to running this IP35 and E4300 @ 3Ghz?

Right. Done some reading. Please rip my understanding to shreds.

Lets say, with an IP35, a 4300 and my OCZ memory. I decide to run 330Mhz FSB to give me a CPU speed of 2970Mhz.

If I select 1:1 ratio, my memory will run at 660Mhz DDR. Ie, underclocked.
If I select 1.25 ratio, my memory will run at 825Mhz DDR. IE, marginally overclocked.

Am I right?

sound about right.

usualy you divide by first number, then second is the multiplier.

so @ 333mhz FSB
5:4 would give you 264mhz or DDR2-528
1:1 would give 333mhz or DDR2-666
4:5 would give 416mhz or DDR2-833
1:2 would give 666mhz or DDR2-1332

In the case of abit, they have given memory options in between to try and keep std memory speed options available for the 1333 CPU's when released.
