As I expressed a while ago, I am interested in Ocing old Pentiums. However, I have hit a roadblock. With my all jumpers mobo, I cannot set the bus speed to 84.4 Mhz or higher without my computer restarting. It says "Loading grub stage2", then POSTs, rinses and repeats indefinitely. At lower bus speeds, it boots fine, but I'd like to get the processor to at least 291 Mhz(or higher). The BIOS says that with bus at 74 the processor is at 52C, while at 84.4 it's only 50C (idle, obviously). Is there something wrong with the probe? I just put new thermal paste on (the cheap Vantec kind), because the old stuff was crusty :dead: , but it's posted since. (I also have a cheap CPU cooler).
