Thanks . I went there first . They only refer to standard chip upgrades. Or atleast that is all I can find . The machines I have , according to Dell , top out at P-III 500mhz with the A07 BIOS upgrade . A site called PowerLeap
offers a product simular to theslocket , but it has it's own regulator that supercessed Dell's onboard . I keep looking Thank you for the advise . If I post a HJT scan could I get you to review it ?? If so I 'll tag it with you user name .
