Transforme um Sempron em um Athlon II X2

helldanger1 · Jan 19, 2010

Nossos colegas do site VModTech descobriram que é possível transformar o processador Sempron 140 (que tem apenas um núcleo de processamento) em um processador Athlon II X2 de dois núcleos. É claro que o Sempron 140 é um Athlon II X2 com um núcleo desabilitado, uma prática comum entre os processadores da AMD (lembrando que os processadores Phenom de dois e três núcleos são na verdade variações dos modelos de quatro núcleos com um ou dois núcleos desativados). Para fazer a “transformação” deve-se usar uma placa-mãe equipada com o chip ponte sul AMD SB710 ou SB750 e que tenha a opção Advanced Clock Calibration (ACC) no setup. Ao habilitar esta opção a computador passa a reconhecer e acessar todos os núcleos do processador.

Sempron 140 Unlocks to Athlon II X2
It has been done over and over again, and each time new AMD processors successfully unlock disabled cores (dubbed "defective"), it only makes us wonder if it is a deliberate attempt by the company to make buying its cheaper processors potentially rewarding. It has been discovered that AMD's recently announced Sempron 140 single-core processor can be transformed into a dual-core Athlon II X2 series processor with a simple, well-known trick. This comes as no surprise, as the "Sargas" core the processor is based on, is made by disabling one core on the Regor dual-core die.

The trick requires a motherboard with AMD SB710 or SB750 southbridge that supports the Advanced Clock Calibration feature. Not all motherboards, however, support this mod. By simply enabling the feature in the BIOS setup program, the system will be able to address both processor cores, with the complete feature-set of Athlon II X2. The staff behind the feat over at Thai techsite VModTech tested for the unlocked core's stability with much success. At 3.71 GHz (13.5 x 275 MHz @ 1.536 V), the processor stood SuperPi, WPrime, and WinRAR bandwidth tests. Validation can be found here At around $40, here's the cheapest ticket to a dual-core processor that looks $80 Intel processors in the eye.
