to bro ah khoo..
wat is the safe voltage for athlon x2 for daily use? im currently using 1.46V @3.1 Ghz

to bro menchelsea..
wat voltage u use to hit 3.3Ghz?

i'm not so comfy runnin my chip with 1.4v & above for 24/7, most of d time i'll just run my chip on default voltage on daily basis. it could be diff to others as it's all down to personal preferences, but 1.46v is a 'lil high to my liking.

try find out wat the higher speed can run with stock vcore ??
if below +0.050v + stock vcore i think should be no problem.
my rig 4200 edy running more then 6 month with setting 250 x 11 = 2750 vcore stock (1.25V) + 0.037 without any problem

@sharkeer
try to find out wat higher speed ur proc can run with stock vcore or maybe a lil bit vcore + 0.050 below

how bout use divider 667 or 533 ??

I think i used 1.5xV to push till 3.31 .
Now at office , i'll post my screeny tonight.

But be careful with the temp.

sorry forget to reply u ??
ur 5200 proc is F2 or F3 ..if F2 cannot oc very high

His one F3 d.Even if F3 not high d.cos the stock voltage high around 1.3xV?
Get Phenom X2 lah $105 only

memtest shows no error with the ram..
i use divider 667 to 1032mhz.. 533 never tried..
since this board doesnt have native support for 1066, i have to oc it..
right now stable i'm using 127.5ns@1000mhz..

hmm.. im using 9950be ..
its simply can oc to 3.2 by adjusting the multiplier to x16 with voltage of 1.47
it works for me... and give me 3mark vantage cpu score of 10k+..

ive tried to oc to 3.4 (+ a bit more of voltage) but when i run 3dmark vantage its crash..
so i stuck at 3.2

anyone have any idea?

Hmm...tell us your overall settings.

EG

200HTTX17
1.45V
DDR2 400 Divider
1.95VDIMM..

Tell us more..

at stock voltage can get 2.8ghz. at 1.376v can get 3ghz.. is this ok?

my setting
200htt x 16
1.47v
ddr2 1066
1.96v

bro, d board does come with ddr1066 divider, but x2 doesn't support ddr1066 natively. i was able to use ddr1066 when i was on x4 9600...

heat? 9950 b.e w/ 1.47v could generate lotsa heat. load temp of all components (cpu, nb & pwm) pls...

well, i would settle for 2.8GHz w/ stock volt. but if temp diff between 2.8GHz & 3 GHz is small, then i'm fine w/ 3.0GHz... just my humble opinion...


try to use lower divider? eventhou phenoms support ddr1066 natively, but some boards tend to dislike it.

Low the divider..To 667/533 at least.Also make sure ur timing is loosen for more headroom.
sharkeer whats ur stock voltage?

@ah_khoo
this board support 1066 on phenom ? hmm.. need to upgrade la like this..
is there any way to oc proc without ocing ram too ?

btw guys, is there a PWM form ram ?

Unlock multiplier proc Black Edition is the answer

Added on September 10, 2008, 3:42 pmU mean ram mosfets pwm ??
good mobo got 3 or more mosfet for ram power phase

some boards have that if I'm not mistaken.

yup, or adjust htt, cpu multi & use proper divider will do... thou it's a bit troublesome...

What some board hv da ??? for ddr2 /dd3 nowday most of the board hv it just u no see it

Example : gigabyte cut ram voltage setting (afaik many rma mobo) becoz it only use 2 fets chipset , no like biostar got 3 fets ,
so less fets make more heat ...more heat fail oc high

i have read somewhere that if the pwm ram is good, then u can set the tightest timing for stock speed at low vcore..

dont know its true or not.. but if it true, how to check the pwm ram ?

See the design like CPU PWM...most of only use 1 phase power

my bad bro, when it somes to spottin those components, i'm abit lost as i'm pro enuf to determine which is which...

IIRC abit ax78 got 2 phase, saw 2 squarish stuff (is it called choke??) near d memory slots...

d more power phase, d more efficient/cleaner voltage is supplied... correct me if i'm wrong...
