NOTES

Regular clock speeds for this AMD Phenom II X4 955 (HDZ955FBK4DGI / HDZ955FBGIBOX) are 3.20GHz (16x200MHz) for all 4 cores and 2.00GHz (10x200MHz) for T-cache with HyperTransport and memory controllers. Shanghai (also known as Deneb) core, 45nm manufacturing process, C2 stepping. This is a Black Edition processor, so there are all multipliers unlocked. The clock speeds have been raised to 3.60GHz (18x200MHz) and 2.40GHz (12x200MHz) respectively with no voltages increased. A boxed cooler by AVC has been installed (model AV-Z7UH40Q001 — copper bottom, aluminium fins and 4 copper heat pipes).

There are two 2Gb memory modules by Micron (Crucial) installed. They're labelled as RM25664BA1339.16SF with 9-9-9-24 timings at 1333MHz effective accordingly to their SPD. The actual timings have been reduced successfully in the BIOS. The memory controller has been set up for ganged mode (i.e. one 128-bit memory channel) rather than unganged mode (i.e. two 64-bit concurrent memory channels).

The overclocked hardware has passed reliability testing prior to benchmarking.
