Motherboard temp is 44c even with the heatpipe? Is this normal. Seems hot to me as I amd not adding any voltage to the proc, motherboard or ram.
*
i guess the 44c is the temp inside the pcb, because when load it will be much more hotter, like 70-80c.

That hot? i have good ventilation as Im using CM690 with all 90CFm fan.
I thought the heatpipe would really help in cooling the heat down.
How hot is your mobo?
*
the heatpipe is only cool the chipset, and we dont know where the mobo sensor is placed.
but it do getting hot or almost same hot as processor temp.
mine idle at 34c for mobo, but my vcore is only 0.976v

there are only 4 of them

Cpu clock drive
PCI Express Clock drive
Cpu clock skew
MCH clock skew

i am also not quite sure but it said to be used for increase the stability at high fsb, i guess we do not need to change it for dualcore until >500fsb.

lol, not sure about that, but i guess no harm..
but if u able to stable at stock, no need change it lor smile.gif

One question here.

can my Corsair XMS2 DHX PC-6400 2x2GB CL4 compatible and gud enuf for OCing with this EP45-UD3R? just wanna make sure.i intend to buy the mobo very soon.
*
for sure it competible with this mobo, but u wont get a high clock due to the chip used in the ram itself.
and there is no d9gmh etc in 4gb kits so any rev is just almost the same.. smile.gif

My CPU over clock at 4ghz. CPU multiplier set at 9. FSB at 450mhz. SPD 2.00B. Memory at 400Mhz. CPU volt 1.25V. Memory 1.8V.
Prime stable with 2 running. SPI running. Hope this helps.
*
u should use dual thread orthos for more accurate result and runing it for few hours. with 3 and 5 minute, it does not show that it is a stable setting smile.gif

wanna ask somethin. anyone use QX6800 with UD3R? what the highest these two can go?

try at 430x8. but prima give hardware error.

if anyone use these two component. can give me ur bios setting? really preciate it. notworthy.gif
*
since your is extreme, just use higher multiplier, keep the fsh below 400 smile.gif

QUOTE(uzer85 @ Mar 1 2009, 04:07 AM)
thx. just do 450x8 on 1.331Vcore. biggrin.gif
any explanation why u suggest me to keep it under 400?. higher fsb is better i heard.
*
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 notworthy.gif

Errr heng,400 with 4:5 divider is DDR 2 1000mhz,2:3 is DDR 2 1200mhz and best pl possible is 5-6
*
yaya, should be ddr1000.. gigabyte default PL for it will be 7 for quadcore, but can tweak to 5 or 6..
if DFI will be 6 or 5 drool.gif

increase Vdimm? 2.2V is quite high oredi. sweat.gif  sweat.gif
*
for your information, increase vdimm will not allow u to get better PL.
u need to deal with fsb strap to get better PL.
u will get the best PL by using divider 4:5
some screenshot from my q9450 last time biggrin.gif

Tried everything and Bios revision is F5.
I can install XP but not Vista.

i also got no problem to install it using a pendrive, for vista and window7, so i guess mostly is your hdd problem?
