-------------------------------------------
I finished with the 3 BIOS files investigation:
Hardware used:
Corsair PC3200 XL 2x 512MB TCCD @ C3-4-4-8 1T 2.9v
Abit NF7-s (Nr. 5) - Max tested FSB with this TCCD kit: 257MHz @1.6v
Athlon XP-M 2400+ (Barton) / AXMH2400FQQ4C / IQZFA 0347SPMW / Y906156K30092
Watercooled
Roomtemp: max 20.0C
BIOS used: Digitalbath DDED
Interface: Enabled
I added the 8x250MHz FSB tests. It seems FF1 is running best with high voltages.
Edit: and I found this:
Mod Biossammlung für AMD und Intel boards*UPDATE 22.11* Hi ich dachte mal das kann vielleicht nicht schaden mal ein paar gemoddete bios zu sammeln. es ist bestimmt für jeden etwas dabei. wenn ihr auch noch welche habt, könnt ihr sie ja posten. es handelt sich hier um versionen von tictac...

Edit 3: Does anyone still have those D24 Subzero bios files?
