|Sorry, I had a lot of things to do yesterday & didn't get back until late. I'm not sure if you're familar with the BIOS so here's a brief description:|
The BIOS (Basic Input/Output System) is sort of a mini-operating system for the motherboard. It's contained on a chip called CMOS (Complementary Metal-Oxide Semiconductor) which is sort of a battery powered memory chip. There's a lithium coin battery on the motherboard that maintains power to the CMOS chip...that is what keeps the BIOS settings stored in memory & prevents them from being lost when power is cut to the computer. The settings contained in the BIOS are the date/time, CPU clock configuration, memory configuration, hard drive configuration, etc, etc.
To enter the BIOS setup program, press the DEL key at startup. There are dozens of other settings but these are the only ones you should change:
Under Advanced > JumperFree Configuration:
CPU Overclocking = manual
CPU/HT Reference Clock = 250
PCIE Overclocking = manual
PCIE Clock = 100
Processor Frequency Multiplier = x10.0
CPU/NB Frequency = x7.0
Memory Clock Mode = manual
MemClock Value = 266
After changing to the above settings, Exit & Save Changes.
Your system will reboot & your CPU will be reclocked to run at 2.5GHz & the RAM should still be at 333MHz. You can verify this by running CPUZ again.
NOTE: if your system refuses to boot, unplug the power cord, open the case, then move the CLRTC jumper cap from it's normal position on pins 1-2 to the clear position on pins 2-3. Wait about 5 seconds, then move it back to the normal position again. Plug in the power, boot the system, press the DEL key & immediately enter the BIOS to correct the date/time, then when you go to Exit, select Load Setup Defaults.
