Well, i was planning to overclock my CPU but i dont know what voltage is suitable for the original AMD Heatsink. since i dont have enough budget to purchase a good cooler, what 's the maximum voltage that i can set to maintain the temperature with my current heatsink?
i'm using AMD Opteron 146 2.0Ghz and i've overclocked it with Overclock AI 30% to 2.6Ghz with default Voltage 1.44V
and i also wanted to overclock my memory. i'm currently using Corsair XMS PC3200 C2PT 512X2.
my board max voltage for processor is 1.450 and the max frequency is 400. i'm currently at 2.60. i've tried to set up to 300 but it crash. then i set to 290, the temp raised to 57.
is there any way that i can raised it to 300X10?
try with stock voltage ( maybe +0.05 ) push until unstable .
my original heatsink ( after lapped ) can keep around 55C load temperature close casing using 1.5V .
default Vcore should be around 1.35-1.4V for most s939 processors .
try to use manual BIOS setting not Overclock AI as you'll learn more especially the memory controller part .
ok , set everything to default and go download a small program called A64TWEAKER
write down these following value (

MEMCLOCK MODE limit
MEMCLOCK VALUE 166 or 133 if unstable
CL 2.5
TRAS 7 or 8 if unstable
TRP 3
TRCD 3
TRRD refer tweaker usually 2
TRC refer tweaker usually 10 or 11
TRFC refer tweaker usually higher than TRC by 2 , 3 or 4
TRWT refer tweaker

hmm...vdimm is voltage?

sorry la..quite noob la...but all my CPU-Z screen shot are there. tell me if anything wrong k..
vdimm is voltage for RAM

what can i do with my old man rig and how? spec :-
AMD64 2800+ socket 754
1.5GB DDR400 ram
Asus K8N4-E mobo
Gigabyte 512mb DDR2 8500GT
400Watt true power enlight power supply.
cause i upgrade my gc last few months back and still only manage to put low setting for Fifa 08. sien . waste of my money.Old man is old man cant help. hehe
to be honest , i don't expect high detail from a 8500GT , try lower the graphic detail .

Guys, i have a problem here.
my system:
Processor - AMD Opteron 146
M/Board - ASUS A8R-MVP ATI Express 200 Crossfire
RAM - Corsair XMS PC3200 C2PT 512X2
at 1st, i overclocked it straight to 3.0Ghz with 1.400V but it crashed. then i try step by step from 2.0>2,6>2,7>2,8 and lastly to 2.9 Ghz with the highest Voltage which available with my board that is 1.450 but the temperature raised to 57 degree. well, is it enough for 1.450 V to boost up to 4.0Ghz???
according to google , your mobo support up to 1.55 for Vcore and 3.2 for Vdimm

.
haha , K8 will never do 4.0GHz easily . some even struggle to reach over 3.0GHz .
