The AMD Phenom II 42 TWKR Black Edition was a desktop processor with 4 cores, launched in June 2009. It is part of the Phenom II X4 lineup, using the Deneb architecture with Socket AM3. Phenom II 42 TWKR Black Edition has 6 MB of L3 cache and operates at 2000 MHz. AMD is building the Phenom II 42 TWKR Black Edition on a 45 nm production process using 758 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. You may freely adjust the unlocked multiplier on Phenom II 42 TWKR Black Edition, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 125 W, the Phenom II 42 TWKR Black Edition consumes a lot of power, so good cooling is definitely needed. AMD's processor supports DDR2 and DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1333 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the machine, Phenom II 42 TWKR Black Edition uses a PCI-Express Gen 2 connection. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability.
Hardware virtualization is available on the Phenom II 42 TWKR Black Edition, which greatly improves virtual machine performance.
