I can only overclock my E2140 till 1.85 Ghz ( 230mhz x 8).
When i try overclock something higher ( 2 ghz etc), it cant even boot and says overclocking / overvoltage failture during the 2nd boot-up ( after switching off the main power)

Any help is appreciated...

CPU:Pentiun E2140 @ 1.6ghz
M/B:Asus P5KPL-AM
Ram:Kingston 1GB x 2 DDR2 @ 667 Mhz
G/C:Winfast Geforce 9400 GT @ 512 MB

what exactly are the settings you are using? it is quite difficult to fail so epicly at oc-ing. Also this should be in the existing E2XXX OC thread

What's the stepping of your E2140? You probably need to increase your Vcore a bit and set your RAM to run 1:1

where to set the ram to run 1 : 1? btw my vcore setting is auto but if manual, there's only 3 options (50, 100, 150) to let me choose.

change a better mobo

not really worth considering how low end the setup is. Might has well change to higher speed proc.

@TS, post pics of your BIOS settings inside the BIOS. I'm guessing you're quite new to OC-ing huh?

will post asap. i got exp on overclocking a pentium 3 only so im reallly new to oc LOL

becos its a cheap ass not for OC mobo. But you dont have to adjust voltages at such low OC speeds. Voltages need only be tweaked over 2.6ghz, unless your proc is totally hopeless. Ram divider is important though, it should be set to 1:1 1st, then later can be adjusted to suit your OC.

urm since im really new to o/c, can i know where to set the ram divider? tq

if u "cant" see the ram divider thingies in ur bios, can u see something can change the ram speed?

Did you google before coming here? I just googled your mobo and from the looks of it, it should be able to do some moderate OC-ing. Heres just a brief sample of what i found:-

What i gather from there is that the mobo itself should be able to do FSB400(QuadPump 1600), which is sufficient for moderate oc-ing. I also notice that it has a G31 chip, so you should definitely disable that before oc-ing. Go read up your mobo manual on how to do that

thx 4 the info.

hm e2140 rox

lama tax jumpe bang

Do a bsel pad mod, then bump it up from there.

before that, run cpuz as well as coretemp

it will identify your original vid as well as stepping.

actually no need .. i manage to OC my e2140 to 2.1 Ghz without Optical GPU(onboard la) , with optical GPU i manage to set up max till 2.9.. and increase oni 0.5 Vcore ^-^ .. isnt it ram timing increase if we increase the core speed aite.. a bit hard to get 1:1 .. try it once but unsuccessfull..
