Hi everyone,
Decided to build a system around this board:
There are a lot of unknowns about the final configuration, but I'm aiming for a Riva128 PCI+ possibly dual VooDoo2 (if both my boards work).
The CPU will be a K6-2 at 400MHz (66x6.0).
The problem is related to the CPU voltage, as the board only offers 2.0 and 2.1 volts and then jumps to voltages that are inappropriate to a K6-2 (2.8, 2.9 and 3.2 volts).
I have a tray of 10 NOS K6-2-400AFRs that require 2.2 volts, do you think picking a random one and sticking it to the board will result in a stable system at 2.1 volts?
Tried to replace the voltage selection jumper with a resistor, used 100ohm to 1Kohm and nothing changes. Can't decipher the inner workings of this VRM.
Of course it would be safer (stability-wise) to use a 500MHz K6-2, it should have no problems working at 400MHz with a slightly lower voltage, but I'd really like to use one of the NOS CPUs.
I also tried my only K6-2+ on the board. It works ok, but BIOS detects it as -MMX 66MHz and my OCD can't live with that 😀
(The K6-2 is detected as K6 3D, which I find nice).
