Wouldn't really recommend trying. Any gains will be fairly minimal and there is some risk in overclocking older parts, particularly since they weren't very high end to begin with.
So what's stopping you?
I already tried to overclock this system
1st i unlock all cores
Advanced clock calibration - All cores
Unleashing mode - Enable
Active cpu cores - Manual
Value all core (-2%)
Cpu overclocking - Manual
Cpu/HT Reference Clock (MHz) - 220
PCIE Overclocking - Manual
PCIE clock - 100
Cpu Ratio - x17.5 3500Mhz
Cpu/NB Frequency - 2200 Mhz
Cpu Over Voltage - 1.42500
VDDNB Over Voltage - 1.30000
Load Line Calibration - Auto
HT Link Speed - 2200MHz
All other settings are default/No change
I tried this settings but i got blue screen error , auto restart error so i increase cpu nd vddnb voltage but still same blue screen error . Please help i want more performance as much as possible from this my old system.
I tried overclocking profile 5% 8% nd 10% with all core unlocked which work fine but when i try above manual settings i got so much problems . Hope some one help me. thank you
