owh ic.too bad i can't read chinese >.< thanks man.better choose UD3L than UD3R then.hehe.

This

try tweaking these voltages:

CPU Termination = 1.25 - 1.35
CPU Reference = 0.64 - 0.67% Of Termination voltage (this is just my settings. might not be accurate )
MCH Core =  1.2 - 1.3

for CPU Reference, there are different theories on tweaking them. from my testing, i use around 0.64 to 0.67% of Vtt. i might be wrong so if u want better answer, try googling more

you might wanna increase clock and mch skew too. that could help a lil if u know how to tweak it

since your is extreme, just use higher multiplier, keep the fsh below 400

yea, theoretically higher fsb giving u more bandwidth, but for a quadcore, to achieve high  and stable fsb, it is more harder than dualcore.
beside of fsb, performance lvl is also important, for a quadcore, to acheive high fsb with low PL is very hard.
when u use high fsb (more than 400) required more vnb and vtt, and u will end up use divider 1:1 which give u PL9 or 10 at high fsb.
if u use fsb 333, u will able to use divider 4:5 which will give u PL6, this required stock vnb and vtt.
imo, the best combination is u can use fsb 400 with divider 4:5, but in this case u will need a ram that capable to do ddr1000 stable, this will give u the best performance of overall.
btw, i am not sure u understand what i am talking about or not

hello guys. new ep45-ud3p user reporting. just got tis board 2 days ago and been clocking all day long. i'm new in oc'ing and tis is my result. i think the temp is very high. hope to get some comments and advices from all the sifu here. my vcore in bios is 1.3 and dram voltage at 2.0, spd is 2.0, ram timing is 5-5-5-15. i'm using 2x1gb kingston hyper x 1066 ddr2 and cooler master n620 hsf. i guess i got the wrong hsf. 

uzer85, thx for fast reply. actually wat i saw from many forums r ppl would recommend temp below 65 is safe temp and i also saw tat other ppl can do better fsb wif lower temp. the temp u see in my attachment is the idle temp. when full load it will reach 66 to 68. i hope to get some advices to lower my temp. thx

down where? i also dont know why. maybe due to unstable clock i think
PL6 is quite difficult to achieve imo. what is your vdimm?

then i think its quite impossible to get PL6 unless you are willing to increase your vdimm. maybe you can try tweaking the RAM termination voltage which im not sure how it actually works.

i know some people that run 2.3v daily

im using 6:5.460fsb

or u cn try pushing it higher like me thn try diff strapings,oc ur ram in the same time  .but seriously i still noob in ram stuffs,timings etc

This is my fresh start & i'm new here 

The bios settings & tweaking i refer from this thread
Risk abit lo see how far can go.

usually we relate ram timing with the ram speed not the FSB.

no la i runing daily on stock la~~~

manage to get 4.6Ghz this morning, but the VCore
