Ultimate Socket 775 CPU Identification
I can only show you the back sides of 775 CPUs I own personally. Thus, there may contain (much) more minor (or even obvious) variations. E.g. the back of a Pentium 4 Extreme Edition Gallatin looks completely different from a Prescott one. I can't show this, though, since I do not own one. I'll try to document every variation I'll find.
Net-Burst Socket 775 Processors
"90 nm Intel Prescott Socket 775"
CPUs known to look like this:
- Intel Pentium 4 5xx Prescott All Steppings
- Intel Pentium 4 6xx Prescott 2M All Steppings
- Intel Celeron D 3xx Prescott-256 E0, (some G1?) Stepping
Some capacitors may slightly differ in size.
"90 nm Intel Smithfield Socket 775"
CPUs known to look like this:
- Intel Pentium D 8xx Smithfield All Steppings
"65 nm Intel Presler B1 & C1 Socket 775"
CPUs known to look like this:
- Intel Pentium D 9xx Presler B1 & C1 Stepping
D0 has slightly altered capacitor arrangement.
"65 nm Intel Cedar Mill D0 Socket 775"
CPUs known to look like this:
- Intel Pentium 4 6xx Cedar-Mill D0 Stepping
- Intel Celeron D 3xx Cedar-Mill-512 D0 Stepping
Core Socket 775 Processors
"65 nm Intel Conroe B2 Socket 775"
CPUs known to look like this:
- Intel Core 2 Duo E6xxx Conroe B2 Stepping
- Intel Core 2 Duo E4700 Conroe-2M G0 Stepping
- Intel Core 2 Extreme X6800
