need some little help here guys
my specs are ASUSP5KR, E6750 --1.4v, 2GB Kingston Ram 800Mhz
anyone experience OC-ing this board before?? cause when i put the fsb to 450 with 8 multiplier, the system failed to boot windows
and as seen in the snap shot my idle temperature is only 29c using gigabyte G power-pro
why is it so?? i have checked from the bios, same temp
thx in advance

has your friend tried to to increase the chipset voltage??
what ram is he using btw??
i just tried fsb 335 x8 @ 1.45v and kingston 800mhz ram latency 5 5 5 20 @ 1.9v, after 1hour50mins the prime95 error ady
what should i do yeah??

i have another question here..
i checked from cpu-z for my e750 1 of the core the multiplier is x6 and the other one is x8 even though i have disabled the speed step in the bios, y is it so??
can anyone help me pls

yeah, found it ady
thx for the help

Added on October 26, 2007, 5:29 pmbro, mind telling me whats the voltage do u put for ur kingston value ram run stable at 5,5,5,20 @ 880mhz??
i cant tends to do so, even running at 860 @ 1.9v ady shown error after 30 mins prime95

u should tell us more about ur system i guess
processor and ram u r using?? and the OC-ing

wanna ask u guys who are familiar with oc-ing
is it necessary to upgrade northbridge heatsink as well??
cause my asus P5K-R board sometimes can go up to a very high temperature (100c) when running stress testing around 8 hours...then it will auto restart it self..idle is around 40+c..
checked using the PC probe is 100+c, and checked from bios it shows "minus" -92c..really weird

i dont really push to max though
if im not mistake northbridge control cpu, ram, and gpu rite??
mine is E6750 @ 3.5Ghz 1.4v using G-power pro, KVR 4-4-4-12 @ 2.1v @ 840mhz
the problem is the cpu doesnt give me a problem with temperature
only the mobo temp is higher than cpu temp
and my northbridge heatsink already has the heat pipe, so wouldnt it be a waste??
or should i just get a fan sticked on the heatsink??

thats the pic, and i dont think the airflow is bad though
yeah maybe i should just try wiring up a small fan on the NB
btw, the mobo temp showing in the PC probe is it NB temp or SB?? or it is combined??

mine is 42c idle which i found it very high, cause it is even higher than the temp of my processor

u better do bro, 60c++ is consider quite high rite???

im running E6750 on asus P5KR and corsair XMS2 DHX 2GB 800Mhz
i need help with OC-ing it
cause i still cant go higher than FSB 420 where others can go up to 450+ pretty easily
i need help with all those setting in my bios..im still new in OC-ing

now im putting Vnb @ 1.25..how much higher should i put?? the next level is 1.4v, isn't that a little too high??
for now, i dont think i have a problem with temp, idle around 26-30c running @ 3.36Ghz
i will try increasing the Vcore again then

no, its just me
i could only go till 3.36Ghz, thats why im not satisfied and ask for help here
go above that i cant reboot to windows ady

may i know what are the possible caused that my mobo temp go up to 150c when i only increase my Vcore to 1.425??

its not only a reading from the PC probe
i have tried to check from the bios, it shows -150c instead, why minus??

after i changed back to 1.4v and 420fsb and restart, it is back to normal temp
will be trying more OC next week, and update here for more help
going back hometown tomorow morning, busy with packing and stuff
Happy Chinese New Year for all
