OK well my friend appears to have switched the I/O voltage with his cpu voltage and hes not sure how the jumpers should go to do it right. He has a k6 jumper setting and a k5 jumper setting. Right now he has I/O at 2.3 and CPU at 3.3 and hes pretty sure thats backwards. His motherboard is a BCM VP1541 (i dont know either). His cpu is a k6 550. Any help would be appreciated.
