FSB 1066 to 1333

Hi,


I've got this problem with my E2180 on this motherboard (http://www.mercury-pc.com/product-spec.php?productid=766)


The problem i have is the PC overclocks from FSB 800 to 1066 without a problem and touching 50*C only at full load but when i increase the FSB from 1066 to 1333 in the BIOS , the computer just shutsdown.


My MOBO Bios has got some extra Function the "Frequency/Voltage Control" tab



Auto Detec DIMM/PCI Clk - Enabled
CPU BSEL Select - FSB-1066 (Other options 533,800,1333)
PCIE Spread Spectrum - Disabled (Other Options "Triangular Down" )
DIMM Voltage Control - 1.90v (Other Options 1.85,1.95,2.00)
NB Voltage Control - 1.375v (Other Options 1.350,1.400,1.425)

I didnt try it with other Voltages cause I'm not a experienced Overclocker. So i thought i would take some advice before i try something stupid or if it succeeds "amazing".

Its not what I said . Its what i wrote exactly from my BIOS "FSB 1066"

Is there a way i can upload my whole CPU txt here?

Alot of 2180s I've had only like to go to 320 or 330FSB back it down a tad.

The problem with my mobo is the features for overclocking is limited.

And the CPU BSEL has only 4 Options - 533,800(Default),1066,1333 . I cannot increase it like after 1066 I can't try 1100 I have to go all the way to 1333 and can't increase my Multiplier either.

Another thing about my MOBO is it supports Core 2 Quads too and the reason why the option FSB 1333 is even available. http://www.mercury-pc.com/product- [...] ductid=766

And the Voltage available.Same here i cant go from 1.85 to 1.86, I can only go from 1.85 to 1.95

DIMM Voltage Control - 1.90v (Other Options 1.85,1.95,2.00)
NB Voltage Control - 1.375v (Other Options 1.350,1.400,1.425)

I have complete control over changing my RAM timings though.

Here's the CPU-Z of my Memory and my CPU

If you think its the 512 MB memory I can get a another 2 GB with exact specifications. Temperatures are absolutely are not a issue here. 1066 on MAX LOAD goes to 54 * C. Very Stable at 1066 but wont even attemplt 1666.

BTW my PSU is Mercury AP 2400 - 385w
