What motherboard socket does the Q9505 require?
The Q9505 uses the LGA775 socket. It requires a compatible motherboard with BIOS support for 45nm quad-core processors.
How does this processor differ from the Q9500?
The Q9505 is essentially the same as the Q9500 in clock speed and core count but uses a different stepping revision (SLGYY), which may offer minor improvements in power efficiency or thermal behavior.
Can this CPU be used as a drop-in upgrade for older LGA775 systems?
Yes, it can replace older dual-core or single-core LGA775 processors, provided the motherboard BIOS supports the 45nm quad-core family and the board's power delivery is adequate.
Does the Q9505 support 64-bit operating systems?
Yes, it supports Intel 64 (EM64T), so it can run 64-bit versions of Windows and Linux.
