I see Command Rate is set to 1T. Are these systems capable
of handling 1T, and at what clock frequency does 2T
become necessary ? I don't know the answer to that, and
I'd have to read a few thousand posts to get some idea
about it. "Command Rate" controls the issue of addresses
or commands over the memory address bus, and a 2T setting
means the address is presented for two cycles.

Command Rate 2T - Address is sampled on the second cycle.
First cycle provides additional setup time.

X Address X Address X

I see you're also running your RAM at 1.5 + 0.4 = 1.9V.
Did you need all of that to get the RAM stable ?
Have you experimented at all with the memory, to see how
sensitive it is to the individual settings, with the
conditions you're currently using ?

An alternate test you can try, is to cold boot a
Linux LiveCD like Knoppix or Ubuntu. If Linux also
freezes in five minutes, then you can be pretty sure
it is a hardware problem.

In terms of test sequences, have you tried

1) Cold boot the OS causing the problem.
2) When the desktop appears, and before there is a freeze,
do a restart. Does the system freeze five minutes after
the second boot cycle ?

or this one.

1) Turn on the power to the computer.
2) Before the computer starts the booting sequence, press the
reset button just once.
3) Allow the system to "cold boot" and see if it freezes.

I'm trying to tell here, whether the stable system condition,
is due to the reboot of the OS, or due to the pressing of
the reset button. It could be that pressing the reset
button, causes the BIOS to do something different.
