Overclocking the E6300 on Asus P5N-E SLI

[siupetpet]

*edit* shoot, sorry, didnt see the cpu/processor overclocking catagory before creating this topic*

hello folks, first of all happy new year!!

just got myself an c2d E6300 1.86ghz cpu and an Asus P5N-E SLI motherboard because the cpu is a good overclocker going beyond 3ghz, and the P5N-E SLI review here at AT sounds quite good.

today with the arrival of the two along with a 550w thermaltake 550w psu, zalman cnps9500 and corsair xms2 ddr2 800 4-4-4-12 2x1gb ram, i put everything together, and overclocking result is far away from what other review sites claimed.

the max fsb the board could post at is 375, giving 375 * 7 = 2.625ghz. in the bios i changed the fsb (qdr) to 1500, and left mem (qdr) at 800, all memory timings @ auto. i also tried upping the vcore to 1.4v, but it didnt help at all. my motherboard bios version is the newer nov 22, 0202 version.

what am i doing wrong? or is it just my bad luck getting a cpu not as capable as ones others got? please point me to the right direction )

thanks a lot everyone

Whoa! The board's max was 375?!!

375 fsb is my oc max. the board's fsb max is 3000 (qdr)/4 = 750. no this is not a typo. and no i am not mistaken

Did you try jumping straight to 401?

 

[siupetpet]

nope. stepping up from 266mhz, 10mhz at a time. just thought my max at 350mhz is a bit premature, comparing to the success stories of many others. i'm still working on it now. already tried different ram and psu. maybe it's a bad mobo.....

so is the bios updated and have you ran memtest?

So it you haven't tried it... how about trying it?

can you drop the multiplier, run the memory asynchronous (at stock) such that the memory and cpu are not the limiting factors, and crank the FSB??

see where the board's limit is, i've read a thread over at xtremesystems where a guy was able to get through a similiar barrier like yours, i forget what he did to fix it.
