At last, Morgan 1.2 relocked to 1.3

[papounet]

It took me many many attempts to unlock a Morgan 1.2.
to be used on a Asus A7V 1.02

To get access to multiplier above 12.5x, I cut the L10 left bridge and connected all of L1 + L10 right bridge with defogger repair paint , then with pencil
didn't boot with bios 1009 or 1011 if multiplier switch on 12.5x (with/without jumperfree mode),


I cut/pencil L10, L3 and L4 to hard-mod 13x and remove L1 pencil , didnt boot either until....

I upgraded the bios to 1012 beta 1,
I choose dipswich setting 12.5 and jumpermode
or jumperfree mode (as long as multiswithch NOT 5x or 5.5x, )
YES, YES, YES, I got myself a 1.3 !!!

I mod L3/L4 to 14x and then the Mb would beep at power-up (1 long , several short). changing the voltage (either by painting or by dipswitch), and/or changing the multiplier) did not allow to boot.

So back at 13x / FSB = 100 MHZ / RAM 133 (SPD: 3T/3T/3T)
as MBM reports higher voltage than what is set, I have jumpered voltage to 1.65V , so MBM reports 1.75, idle temp =43C
If set voltage 1.85V, MBM reports 1.95, idle temp =46-48C.

Sandra CPU 3653 / FPU 1785

I will now focus on FSB / ram tweaking, and watercooling

At some time, there were Roadmap of AMD showing a Morgan 1.4,
did anyone see one ? and could post a picture ???

The best picture I got of a Morgan 1.3 was
at

It confirmed the info at

and of course the Info from John C.

the saga continues
(all voltage below are voltage set on MB, voltage reported by MBM are .1V higher)

As I had settled for 1.3 (because of no boot +beeps at 14x @ 1.85v ),
I lowered the voltage to 1.60V =>OK

then I upped the FSB to 107MHZ and bingo the same symptoms, which disappeared when voltage back at 1,8V
the PC is now setying the benchWU at 13x 109FSB PC133/2T/2T/2T

As neither the board nor the Morgan allow to set voltage higher than 1.85V, I may have to do the voltage mod to my trusty A7V to get this 14X which has become an obsession.

Heat output has also much increased :-(
