u need 1.52v for sp 32M stable @ 2.90Ghz, ofcoz prime w orthos @ 3.0GHz w 1.45v vcore will fail rite away. orthos needs more voltage to be stable if compared to sp 32m. in ya case there was even 100MHz increase of cpu clock, definitely it need more juice...

If that so.Someone had achieved 3.0ghz using 1.47V no error in orthos..= = But when i have increased the voltage up to 1.55V STILL FAIL!

Different proc different oc ability. Mine can achieve 3.2Ghz(orthos 2hours) with only 1.5V back then when i used 4000+. Sold that lovely gem to my fren.

In your case, i think it may caused by the ram. Try set trfc 195 and MAL 10(instead of 8 u set). Set 2T and use CL5. No need to pump vdimm that much la bro. Yoour ram is stil in its underclock rate. Report back here.

steppin bro... steppin...

if like that most of d bros here can do 3.3ghz w/ their f3 @ 1.4x (some even lower) but how come mine need 1.5xV n it's not stable...

Ah khoo.Its same proc with mine 4000 G1 Brisbane = =

nadeng..will try.

again... diff in steppin affect alot when it comes to overclockability.

Err.. it's the same stepping la bro. All 4000+ brisbane use G1 stepping. What our fren amdathlon was trying to do was comparing his 4000+ with others 4000+. It's the same stepping but god knows why certain proc oc higher than the other eventho it's based on the same material and technology.

It's like buying a guitar. You buy the same exact 2 guitars but only one will give you more feeling when playing.

Ermm...I will say different batches make overclockability different.
I think ah_khoo typo there already.

Even the processors in same batch are produced, overclockabilty still can be different.

-pWs-

all chip come w d code like XXXX YYYY where x equals to year & week while y are alphabets.

ofcoz u cant compared steppin refered by cpu-z coz it's in general format only.


for eg:
bro dblooi got f3, mine oso d same. but his is 074x ABCD, but mine is 0715 RPMW, his can clock up to 3.7~3.8GHz, but mine can't, get my point...

or if u like, call it diff in batch instead of steppin.... back in socket a time, they called it steppin instead... i've benn talkin too much so i should stop here...

FYI, different batch of proc vary in oc ability
and my F3 sales experience told me that,
even if you get exactly same batch ( maybe you search online, get those legendary godlike batch numbers),
there're possibilities you will get weak proc as well.
of coz, the chances to get good proc is higher if u pick a good batch
Every proc is unique , there's no two identical proc in world
it's all depend on your luck

Got your point aidy.. hehe..

never expected v6 already at 104 page.anyway do ur heard about incoming X2 4850E mild oc 1.3v can get 3.0ghz?

any f3 can pwn that chip, but maybe when it comes to power consumption, d "E" chip will be better.

Btw,the motherboard also playing aspects in Ocing too right?Maybe my mobo probs?

mobo, ram, proc, psu, will effect ur oc

Everything has to be taken into account. And not all proc has the same oc-ability. Doesnt mean yours can achieve 3.0ghz at 1.45v vcore if someone else could. Should I say luck plays the role too for getting good batch ?

not if d chip came from bro dblooi's hand...

dblooi got a lucky hand..wonder which hand he uses to pick the chip? left or right

both hand

Guys one very2 easy question.....what is the difference between a AMD Athlon 64 X2 5000+ OEM (2.6GHz / 1MB / 65nm / 65W) with
the Black Edition one
