i measure all voltages with multimeter (vdimm on the 7th pin in DIMM socket and vcore on the mosfet's leg). so....

@ 260x10 (CoreCenter @ 1.80vcore), BIOS 1.4B1

IDLE ---> 1.77v and 3.88v
LOAD ---> 1.82v and 3.82v

as a matter of fact i'm not using SATA, just PATA. as for SATA it's advised to use 3 and 4 ports when overclcoking and locking AGP at 67 (if you didn't know that already).

i'm using Fortron/Source 530W with one HDD and CDRW, GF4Ti4200.
rails fly little bit higher at 12.20v/5.20v/3.40v LOAD

i don't have any SATA drive so can't check if it might be the problem
