Im having a Kafkaesk issue with my Gigabyte BX2000+
The board dosnt like the combination of high multipliers and 133 MHz FSB, multipliers 6.5X< works just fine with 100 MHz FSB but not with 133 MHz FSB.
The board posts but hangs before the memory test, the board works fine at 133 MHz and even 153 MHz with lower multipliers, 6x153 MHz is Prime95 stable with a PIII 800EB. Its probably a BIOS issue as the release BIOS is from late 1999 when the P3 800 was the fastest (Intel) CPU in existence and consequently the board fails to identify the P3 933 and P3 1000 when running 133 MHz FSB but identifies them as the then existing PIII 700/750 at 100 MHZ FSB.
Its a bit hard to understand why the board needs a BIOS update though as it shouldnt need BIOS support just to run a higher FSB with CPUs that are working correctly at 100 MHz FSB. The board has the PCI/4 divider and as Im not using the AGP-slot nothing runs out of spec, well the chipset does but as I wrote its stable at 153 MHz FSB with lower multipliers...
To update the BIOS in the middle of my benching isnt optimal 😒
