Hello all

i got some question here about overclocking my Phenom II X3 720 batch number 0906EPWM

my proc is stable when unlock to quad core and oc to 3.6GHz 200*18 (idle 38°c and full load OCCT test 1hour 47°c)
my question is, why i cant push over 3.6GHz like other people's proc ?

check this out - Success OC
my system setting as below :

Mobo - Asrock 870 Extreme3
Proc Cooler - Hyper N520
Ram - 2x2GB Team Elite 1333
HDD - 320GB Barracuda
GC - XFX 5770

if got forumer who are OTAI in AMD oc pls help me with

diff people diff system diff hardware same skills...... + diff "LUCK" !

i know that..but, i tried to increase my vcore to 1.5v also cant get it
my system cant boot to windows..i review got people got proc+mobo like me and he can reach it

dude try loosen you memory timing to 9-9-9-27-36 with 1.65v

check your ht link ... make sure its the same as NB frequency and around 2000+-

get xtra cooler for your mobo chipset and cpu.


last hahaha pray you're lucky enuff to get 4g lol

my ram timing is loose enough 9-9-9-24-33 at 1.65v
HT link i didn't adjust..default is 2000..i just push up my multiplier to 20*200..and result is..i cant loading windows

i know, not at all oc'ed can be done success bro..anyway, thx for advise

or maybe you can try this:
200x19=3800mhz
201x19=3819mhz
202x19=3838mhz
... ...
210x19=3990mhz
211x19=4009mhz

see how far this chips can reach?
and since this is deal with base clock, so have watch out other clock like HT link clock, CPU NB clock, DRAM clock.

thx so much for that information/advise, bro Saturn..will try it later

now i tested my system 250*14 - 3.5GHz without touch multiplier.
at this setting my temp is 42°c on idle and 55°c (side panel casing closed - not so good air flow i think) when i put a stress using OCCT for 10minutes
i reduce my ram speed to 1066 and become 1333 when i push up my bus speed
HT link and NB i adjust by myself to 2GHz

dont jump straight away dude..
and 3.6ghz is good edi what..
accoding to here, http://forum.lowyat.net/topic/1003744
they max out lesser then u.. and ofkos they have diff batches..most of em using 0904..

try posing out at AMD OC thread.. cloudwan, the very experienced user of 720 will lend u a hand..kekeke

ok2...nt aku try put more stress on ram aku
lau ram aku pecah, nangis x blagu ar aku

aku plg brani usik multiplier n vcore jer..NB/HT/RAM aku jarang2 usik apa2

tp aku review batch 0906 cam aku ni antara 10 yg plg success

Play around with the settings
And also record down what you did for reference

all setting that i made was recorded
btw thx for gimme some lesson about it

Hi all...

i also use this proc.my question now if i want to unlock to x4 i must increase the vcore or no?coz now i use mobo not have acc function.and now my proc with oc setting 200 x 17.5 with 1.344v.

i think go back to stock setting first, then only try to unlock.
because after unlock, the overclock ability of the chips is different already.
but what motherboard you are using?

Still use old mobo no have acc function DFI DK790Fx SB 600.Juz need to know after oc the setting still same with with unlock setting.Its it different bro?

maybe not the same.

"With ACC turned off, the X3 720 ran Prime95 for an hour at 3.3 GHz before we shut it down (3.4 GHz would crash almost immediately). Using the same voltage and 16.5x multiplier, we tried the same thing with ACC enabled and all four cores cranking. It didn’t take long at all for that fourth core to spit up an error, forcing us to scale back to 3.2 GHz for a stable run."

Thx for ur info dude.
Next time try to get mobo got ACC function.
Now budget still not enough.

haha, get SB710 or SB750 motherboard.
the new SB850 motherboard, don't know still got ACC function in it or not.

mine Asrock 870 Extreme 3 SB850 got UCC/ACC function
i think can go with it because very2 cheap unlock mobo

worth around RM320 new brand and other people said it better than 785G and 790GX old series even used AMD870 and SB750

i see, thats great. because last time don't know read from where, say amd already take out the ACC function from the SB850.

maybe SB850 stable compare to SB710/SB750
