iirc for gigabyte mobo it is known as Vfsb ...its the same as Vtt... jsut that u might not have GTL ref option....

im nubee here, btw just wanna ask something,
how do we know which stepping for the proc is the best for OC...

its differs for every the proc models...

like e8 series is said to have better OCing ability with E0 stepping compared to C0...

while q6600 is said to be better OC n running cooler on G0 compared to B3....

for those comparison, it doesnt mean that C0 cannot clock better than E0.... most of the time its down to the ability of the proc itself imho.... just that getting the better stepping increases ur chance of getting a more OCable proc...

my 2cents...

let say im using a p4 630 proc with N0 stepping, but from what i heard from my friend the best stepping for OC is G0 stepping because from my understanding the stepping or revision is to show the improvement of the proc? is it? just asking and correct me if im wrong.

not sure bout old models bro.... what i know is only from current models....

u are right new steppings normally comes with improvement.....try google for q6600 G0 vs q6600 B3 and u shud be able to get a picture of what difference it brings already....

Hey guys, so far I only mamaged to overclock my e8400 proc to 3.15GHz..(1400 FSB). Weird thing is, when I try smaller increments (1410, 1450 etc) I won't even get to the POST screen sometimes after restart but if I go straight to 1600 Mhz, then I get to the point where windows finishes booting ( the moving bars thing disappear) but the next screen fail to display. Right now my cpu temperature is around 45C with intel stock cooler (lazy to buy cooler la..)

So the thing is, I dont' think it's the heat right? Could it be not enough voltage? I see most ppl can oc their e8400 to quite high, at least 3.6ghz.

well...try increaase the vcore then... shud do the job for u... donot put the vcore on auto

overclocking my E6320 B2 stepping. only able to push it till 2.3GHz with my Thermaltake Mars 9 even i have increased vCore . i ran orthos and prime95. both of stopped half way and said hardware failure. is it my processor not stable with the clock speed?

Could be your ram holding you back

newbie here... ive been reading the guide in OC since while ago.. basically ive understood the theory about how does it go...
however, thr's still one thg i cant get... i dun understand the ram timing and divider thing.. can someone xplain it? thx in advance...

There's some explanation of these settings in my guide. Take a look here:

wow... those guide and fact rily help me out... thx alot dude...

Added on November 15, 2008, 9:47 pmermmm... im getting confused again...
is the ram and ratio thing works the same way for both amd and intel?

This post has been edited by sheenho: Nov 15 2008, 09:47 PM

used to play amd in the past and currently oni intel..i tink its the same...juz that using different term..

i cant understand at all with these oc

can someone help me?
i just assemble my new rig which is as below
Q9400
DFI LT X48 TR2
DDR2 667

my cpu clock only detected as 2.0Ghz why?

and , did my proc support till x8 mulltiplier?

IM NOOB

yes.... ur q9400 has max multi of 8....

the clock is detected as 2ghz most possibly due to C1E or EIST functions... disable those n it shall be 2.66ghz again....

if not, check ur multiplier settings in ur bios to see if its set to 8.....

to start OCing, read all these basic first

thanks tkh, thats help alot
btw, for my rig.. should i upgrade my current ram to high performance ram? what would you suggest? i mean which one, i need 4GB for my work\
thanks in advance

hmm...normally a 2x2gb 800mhz ram wud suffice since quad core fsb normally will be walled at 450-470 like that....

value ram can OC oso if u want...just that u will have to run at loose timing

if u want performance ram for 4gb kit, iirc it shud be at a price tag of around rm300-400 in garage sales.... generally performance 4gb will OC to 9xx at CL4 and 1xxx at CL5

Personally, I feel that the price of performance ram does not justify it's performance gains. A minimal gain in performance (probably 3-4%??) for a huge gain in price....

Like tkh_1001 said, 2x2gb at 800mhz would be sufficient...... even a 2x2gb at 667mhz won't make much real-world difference....

Of course, that's my opinion

oh no, i just bought OCZ OCZ2RPR10662GK DDR2 1066Mhz PC2-8500 Reaper 2GB Dual Channel (2 X 1GB) 5-5-5-15 two set

... ( money floating around lalala sad

No need to be sad la... if you have money, go for the best!

Just remember that 4 sticks of ram (4 x 1gb) is more difficult to overclock than 2 sticks (2 x 2gb).
