the vcore look like abit too high

yeah..thats what i got if leave all setting AUTO in bios..
will try to manually set it after this..
and what other thing/ setting that i should change..

after im read some post here...ppl just using 1.2 or 1.3 only for Vcore..is it possible with mine?

Look at my sig. That's my current vcore

PCI = 33MHz
PCI-E = 100MHz

-pWs-

i believe u can get lower vcore if u test it by slowly increasing ur clock to see how far it can go with lower vcore...

and the temp u can use the one from coretemp as reference with tjmax set to 100c.......

as u OC, if adding vcore by quite an amount already also cant seem to help stabilise the clock, u might wana adust ur vtt/vfsb and Vnb...

if ur mobo have gtl... try mess around with it also...

vcore on auto is kinda

@metsatsu
can u share out your bios setting?
thx alot

so..looks like i can use ur speed as my stable target..
will try to experiment tonight..

just my cooler holding me back..
just using AF 64 PRO only..

thinking to get CCF.. or xigmatex ..

or any recommendation?

and post here..
im still noob in OCing intel Quad..lots of thing to adjust..

me too noob in quad OCing, hope all sifu here can share out their stable OC bios setting, thx alot

actually imho OC settings cant really be shared tho cos each chip has different potential and the hardware pairing is also kinda different....

all that can be done is just share information on how to get stability imho... the rest have to try out and experiment urself liao

my setting in bios is as so:

Vcore = 1.3375v
FSB voltage = 1.3v (if default is 1.2v can't remember )
MCH voltage = 1.6v (if default is 1.5v can't remember also)
PCIE voltage = +0.10v dunno what value and why wanna increase it, but just doing it for the sake of it.
PCIE frequency = 101mhz
FSB:DRAM ratio = 1:1
ram timing = 4-4-4-15
DDR2 voltage = 2.05v
Loadline caliberation control = auto
436 x 8.5 = 3700mhz

the rest i didn't touch

but as tkh bro said, each mobo are different from another. this values which i used on my Gigabyte X38-DS5 can only be used as reference for other ppl. hope it helps in some way.
and for those who think i can improve and correct. please share with me yah.

yea, but just for references as vnb and vtt voltage will be similar i guess

btw, do u think my psu enough juice for my rig?? with q9450

actually different mobo, proc chip potential and ram settings will need different Vnb and Vtt....

regarding ur psu, i think its still ok ok cukup makan ba

I like to play safe. and i seriously believe that a better PSU will enable higher oc for certain components (i can be wrong, but i'm just saying this based on my past experience). 460w should be just enough i guess, but if u plan to oc hard out on your new proc. u better look for around 500w+

yea, i feel the psu need to change also, 12v only 384w
but lack of $$ now..

i think gonna use this as 24/7 first before i get a better psu

Attached thumbnail(s)

My Q9550 E0 stable at 3.4Ghz at stock (1.25v) and at 3.61 (425x8) at 1.2625v..it was a little bit weird i think, coz it is prime stable at 3.61 stock vcore but whenevr i play games, my pc will crash..as for temperature, my core0 is the hottest with 57c during priming at 3.61 (ambient is 25c)..

It cant boot to windows at 3.825 until vcore around 1.32..will try to prime it at that speed when my TRUE arrive with 2 scythe 110cfm fan (push n pull config)..My cpu temp will rise up to 64c juz for few min of priming at 3.8 with my current CCF..

in bios just have 37.3MHz and 66.7MHz or DEFAULT aka (GC killer)

Added on December 3, 2008, 5:32 pmyeap.. just try new setting...
voltage manually set to
VCore = 1.31v
MCH etc all bump 0.1v
pci freq change to 37.3
FSB:DRAM set 1:1
ram timing and voltage leave to auto.

test using OCCT v2.0 stable 1 hour..
@3.77GHz..temp on core 1

my mobo kinda hard to OC coz some time when im just 'kacau' RAM setting.. i end up reset the CMOS.
haish..

finally get 3.5ghz 10 loops pass on IBT after tuning on the gtl ref
dfi x48 lt is really tricky for quad overclocking
anyone using these board pls share me the gtl ref for quad at 450fsb and higher, thx alot

wrong, it is the QUAD CORE which is tricky to overclok.

after done some research for few days, this is the outcome i found.
compared to gigabyte and asus, these board are easily boot up a quad core at 450fsb or more without tweaking in gtl ref,
as for dfi x48 lt and ut version, if dont touch on gtl ref, u cant boot into window at all at 450fsb.
after 400 fsb, gtl ref need to change to make it stable...

or maybe i am wrong, just my psu not enuf juice ?

hhmm... not sure about the gigabyte X48. but my X38 is already struggling when it slowly touches 450. I was able to reach 450 when i was still using my Q9450. but then i have to increase the voltage all the way up to 1.325v and my vcore temp jumped up by 10c!!

As for your psu, it's rather subjective to conclude if it's underpowered. so yah, too bad... can't really tell. i would always spend some extra money to get higher power psu, to make sure that i dun regret later.
