There is a number of Intel Pentium Dual Core 1.8 Ghz
We need to know the exact model number. Could you please provide? For Example: E4300...E2160... and if you could provide the sSpec number even better.
sSpec Number: Also known as specification number. A five character string (SL7AA, SL8VN, etc.) that is printed on the processor, and used to identify the processor. By knowing the processor's sSpec Number, you can find out the processor's core speed, cache size and speed, core voltage, maximum operating temperature and so on.
