This CPU is identical to the Intel E8400 in every way including overclockabilty. The only difference is the name. This CPU has been tested by us at PC Maniacs on Gigabyte X38-DS5 and EVGA 780i motherboards and show as Xeon E3110 3Ghz, the same is replicated by CPU-Z in Windows. This CPU is a great altenative to the E8400 if we are ever out of stock
