u know.. i'm getting sick with so called True Power PSU for OC..
i'd also got same experiences as yours..

using True Power PSU cannot oc high..
using chapalang brand can..

if others component compromise with the True Power PSU.. why cheapo PSU i using almost 1 year not fail me once? that's totally mean not other hardware problem.. the True Power PSU is the culprit..
(it's not a reason when we paying RM500 for the PSU should have incompatiblity issue - it's just sound stupid and will baffle us forever)

if others keep telling using normal PSU will lead to damage the hardware... well i'm not going to use my rig forever... afterall it's needs to be replaced..

for ur info i've tried using CM.. yes CM...
to be precise.. CM ACLX 450W.. cannot powerup my system.. weird eh?
even using 400W chap keretapi berapi is no sweat..
is it becoz of the dual rail?
haih.. these days buying PSU also base on luck..

RIGmaster

it's better for u stop OC la.. 3.8 to 4 or 4.5ghz not a big different i think..
unless u can achieve 5ghz..
if u manage to get good upgrade (psu, mobo, etc) is it worth to pay? better get higher clock cpu then.. and oc more...

but psu thingy.. still baffle me.. haih...

lol oc sampai pokai..
