revilo can take a look at this..what do i need to change?

MB Intelligent Tweaker(M.I.T.)
Robust Graphics Booster ...............: Fast

Motherboard Voltage Control
Voltage Type.………... Manual
CPU
CPU Vcore….……….........................:1.30 <<<< depending on your chip. some chip can do with 1.25v. some cant. so its really up to your chip
CPU Termination…..... 1.200V*.......: auto <<<<< either put it to "normal" or 1.2
CPU PLL…………………....1.500V*.......: auto <<<< either put it to "normal" or 1.5
CPU Referen.…………....0.755V*.......: auto <<<< "normal" should be fine if you not going extreme

The settings below need to change too?

Channel A Reference 0.900V............: auto
Channel B Reference 0.900V............: auto

lol.i seldom go 24/7 la.will switch off my comp before going to bed evryday.as long the temps are ok at idle any vcore is ok i think

btw e8400 is safe @ 74.1 c according to intel

err i just bought ud3r.. its a good mobo indeed!

but i wanna try tweaking manually

ham_revillo can u help me with this

i have an e4500

Just asking, how much of a speed bump can I get if I swap my EP35-DS3 with a EP45-UD3P? Right now using a X3350 C1 ad CM Hyper212 for cooling, not in an a/c room.

i would say not much difference. iinm the difference between P35 and P45 is the south bridge and more tweaking option for OCer. if you dont really OC, then i think you should stick with P35

Sorry, should have reworded my post. Actually what I meant was how far can I overclock my CPU on a EP45-UD3P given that I'm not using the computer in an air conditioned room, and without breaking into unsafe voltages for 45nm CPUs, as I'm aware that mobo swapping, like low latency RAM gives very negligible bonuses.

i would say P45 board are much better in OCing. mainly due to extra feature in bios. all those extra tweaking option makes you achieve higher clocks and fsb. so yes you might be able to OC even much higher but still need to depends on your proc batch. if you hit your proc wall, then no matter how good this board is still it wont let you pass that wall

OK, thanks. BTW, regarding proc batches, What's the minimum FSB wall for my proc anyway? If it's minimum is 450FSB I'd consider an upgrade worth it.

Mine's L803. Found a pair each of Q9450 and X3350 procs on HardOCP's Core 2 Database for that L803 at 3.0-3.8 gigs on asus rampage formula, I guess that means it's a decent batch?

Err chip differ from chip to chip
But if i am to make an assumption,i will say 480FSB stable is pretty easy
After that take more and more gtl ref/vtt tweaking
And quad core fsb wall is depend on a lot of factor,like vtt/gtl/vnb and so on
So if you are pro in tweaking,you might even get 510FSB-520FSB stable

510fsb on quad is rare especially on air imo. besides that, to get to above 500fsb, require hours of tweaking plus benching.

just want to ask, the chipset temp is quite hot. i cannot touch it with my bare hand. is it quite normal?? i set it to 1.26v. im thinking of changing it to 3rd party cooling...
