Hi, Kev.

Is completely bullshit?
I would assume so.
But these pages explicitly state that TP240X can take a 256MB DIMM,
I'm curious if which side is wrong.
If I'm proven wrong and TP240X can actually go to 320MB, it should
be a real breaking news for other 240X users.
Post by KevIs there a way to turn OFF the onboard memory through clever BIOS
modifications?
I don't know if BIOS tweaking can disable the onboard memory or not.
Instead, let me give you one more piece of crazy idea. It is possible to
overclock the Celeron of a TP240 (not TP240X) from 300MHz to
450MHz. This guy succeeded in this modification.

This modification involves two processes. One is to change the FSB from
66MHz to 100MHz. The other is to raise the core voltage to the point
where Celeron works at the faster speed. (In this example, he changed
the core voltage from 1.60V to 1.65V but this should depend on
each individual processor.)
Again, I don't recommend this since this is obviously a VERY
DANGEROUS modification. Only if you are reckless enough,
can collect information and understand what you are doing from
the images of this page, you can be successful.
If you are successful, you will get a TP240 having a Celeron running
at 450MHz and memory up to 320MB.
Good day.
