has anyone been able to upgrade Very old motherboards with Intel i486 Overdrive CPUs?
i have one of these.
Core Frequency: 100 MHz
Board Frequency: 33 MHz
Clock Multiplier: 3.0
Data bus (ext.): 32 Bit
Address bus: 32 Bit
Voltage: 5 V
Introduced: 10/1994
Manufactured: week 04/1995
L1 Cache: 16 KB
CPU Code: i486 DPR
P4T
Intel S-Spec: SZ959
Package Type: Ceramic
PGA-168
but i have a fic motherboard that does not have that cpu listed because the cpu was released time after
486-GVT-2 Motherboard Settings and Configuration
http://stason.org/TULARC/pc/motherboards/F/FI … -486-GVT-2.html
it has a jumper setting for:
CPU clock 1X JX1 pins 1 & 2 closed
CPU clock 2X JX1 pins 2 & 3 closed
so the cpu has a clock multiplier of 3x and the motherboard as clock multiplier of 1x or 2x.
and the P4T model is not listed as option in the manual, so i wonder how can i use that cpu and set it up correctly to have the full 100Mhz, the cpu is 5v thats good as the motherbiard
