My inspiron 1150 has pentium 4 at 2.66 but only runs at 1.6. How can I make it ran at full speed? -2.66 mhz
You need to get the right CPU for the system. The 1150 supports only desktop P4 CPUs on the 400 MHz bus. Sounds like you installed a mobile CPU, which will lock at 1.6 GHz.
Thanks. The p4 2.66 I had runs is fsb533 intalled celeron 2.4ghz at 400fsb. Now runs full speed.
Welcome to the Community,
Just wanted to confirm which tool or application did you use to test the CPU speed ?
I suggest you to refer to the link below to find out the processor speed:
