Hi there

I have the following which I have overclocked:

Asus P5KC
OCZ PC2 6400 2GB
Intel E2160 1.8GHz

I've managed to get it to 3GHz on the stock voltage (9x333FSB). I cannot seem to get past 3GHz, I've tried lowering the VCORE and increasing it but no matter what I do it just will not boot.

Does anyone have any suggestions please?

P.S. Does anyone know how I can unlink the memory from the CPU to make it 1:1?

Try upping the VTT / NB voltage a notch or two.

Tbh, you'll be lucky to get that much higher on an e2160 - My g/f's won't boot past 2.9Ghz.
 
I've got a load mate. C12P, U12P, Coolink Silentator, and Sunbeam Core-Contact Freezer. They are all quite similar performance, I dont think its the cooler holding me back though, the temps are v low.
 
tried a lower multi and more fsb?

post up a pic of your bios overclocking screen dude

i dont think you will get much more than 3.2 out of it tbh
 
hhmm

well if the volts are set to auto then you may run into issues

dont forget to mention the VID and temps too
 
ah - the The VID is the "stock" vCore for each chip - it varies from chip to chip [depends on batch]

the higher the VID the more volts you need to get the computer stable at stock
this is read automatically and set in the bios without you needing to alter volts yourself
overclock needs more volts, therefore - the higher the VId the higher the voltage needed for a bigger clock

you can find your VID [and temps] by posting a screenshot of coretemp

for instance
my q6600 has a VID of 1.325V

so to get stable at 3.4 i need to have it at 1.3500V

its just how it 'scales' for want of a better word
 
no probs - i might not read it until later tonight - but if you are online i will do my best to help
 
Ok Core Temp reported the following:

ok - well with a vid of 1.3250V you should be able to get to around 3.2 at a push

i would think that would be the max tbh

first eliminate your ram
so set it as close to stock settings as you can
eg- for 800mhz - use a divider that puts it at that speed
use the rated voltage for your ram etc

the ram you are using [if a 2X1GB kit] shouldnt need an adjustment to the NB
just probably set it to stock - rather than auto

then...
try upping the Vcore to 1.3500V

then put it at 400X8 see if it boots

if it does [and its prime stable] for a 30mins

try lowering your vcore by a notch - then test

repeat until it becomes unstable [this way you use the least possible volts to run the chip at that clock]

out of interest - what cooler ae you using?
and what are your 100% load temps like?

if that fails...

whack up some pics of your bios so we can see what bits you have that might aid the clock increase
 
Thanks for the help mate.

I'm going away for the weekend right after work so won't get chance to do this until Sunday evening but I'll be sure to post up. My P5KC board doesn't allow me to alter the divider - well from what I could see - it allows me to set my RAM at certain MHz though.

Installed at the moment I have a Noctua NH-U12P but I have a range of coolers I could install, to be honest though the U12P is the best out of the lot of them. (Silentator, C12P, U12P, Tuniq Core-Contact).

100% load at 3GHz with the U12P gives me around 35-38 temp.
 
Probably FSB limited.

The E2xxx chips very often struggle to get past ~340 fsb.

If you've a low multi, you're stuck.

Even my 10x multi 2180 runs out of FSB before the chip runs out of overclock.

ah right - assumed they worked similarly to the E6XXX chips

sorry - may be best to try a higher multi with a lower fsb then
