when replacing the resistor get the same type (different value of course) by desoldering the correct value from another PCB.

there's another unknown bug,but don't have the time at the moment to identifty it as it affects Blizzard PPC cards at very high speed.

i have a modifyed A1200 motherboard which will help me find this bug along with Blizzard PPC card with a fixed Frequency speed to help find what the problem is.
