CPU-Z is a freeware detection program base on the Panopsys hardware detection engine.

It allows to get some information on your system, including :

· Processor name and vendor
· Core stepping and process
· Processor package
· Processor current core voltage
· Internal and external clocks, clock multiplier
· Partial overclock detection
· Processor features, including supported instructions sets.
· L1 to L3 cache information : location, size, speed, technology.
· Motherboard information : name, vendor, BIOS, chipset, memory, AGP.
· Memory information : size, type, timings, specifications.

CPU-Z also provides several tools :

· A complete report, that includes CPUID, MSR, PCI device list, SPD, DMI.
· A cache latency calculation tool

This tool computes the real latency of each cache memory level. Notice that the reported sizes may not be the correct ones on CPUs that use an exclusive L2 (for example a Duron will report a 128Kb L2 cache size instead of 64Kb, because the L1 size in included).

Moreover, notice that using this tool if the CPUs is heavy loaded can provide bad results. Please use the "Refresh" button to restart the calculation.
