Yet to update my sig. My new setup:
AMD Phenom II X4 940 3.70GHz (18.5x200) @ 1.45V
NB speed 2400MHz, HT speed 2200MHz
RAM speed DDR2 800 2x2GB (5-5-5-15)
WinXP 32bit SP 2
WCG-BOINC Manager 6.2.28

3777 floating point MIPS (Whetstone) per CPU
8399 integer MIPS (Dhrystone) per CPU

This is just temporary. I will change to Linux FC9 soon. Not sure if the o/c setting is stable in Linux. Should I go 64bit?
