The Phenom model numbering scheme, for-later released Athlon X2 processors, is a four-digit model number whose first digit is a family indicator. The model numbers of the Phenom line of processors were changed from the PR system used in its predecessors, the AMD Athlon 64 processor family. AMD Phenom-based processor familyĬPU features table Model naming methodology The program was said in December 2007 to have received "minimal functional testing." ĪMD launched several models of the Phenom processor in 20 and an upgraded Phenom II in late 2008. This method causes less performance loss than previous workarounds. Īn AMD subsidiary released a patch for the Linux kernel, to overcome this bug by software emulation of accessed- and dirty-bits. "B3" stepping Phenom processors were released Mawithout the TLB bug and with "xx50" model numbers. This penalty was not accounted for in pre-release previews of Phenom, hence the performance of early Phenoms delivered to customers may have been less than the preview benchmarks. BIOS and software workarounds disable the TLB, and typically incur a performance penalty of at least 10%. īefore Phenom's original release a flaw was discovered in the translation lookaside buffer (TLB) that could cause a system lock-up in rare circumstances Phenom processors up to and including stepping "B2" and "BA" are affected by this bug. The processors are on the Socket AM2+ platform. Below you can see the screen shots from CPU-Z of the overclocked processor.AMD considers the quad core Phenoms to be the first "true" quad core design, as these processors are a monolithic multi-core design (all cores on the same silicon die), unlike Intel's Core 2 Quad series which are a multi-chip module (MCM) design. At 3.0GHz, the temperature peaked at 56 degrees Celsius. I was able to get the system to boot at 3.3GHz and it remained stable under the Orthos Stress test, just when i tried to run 3DMark06 it crashed, this seems as if its being under powered, but i didn't want to increase the voltage past 1.37V. This was achieved by simply increasing the multiplier to 15x, leaving the FSB at 200MHz, and slightly increasing the voltage. These figures are important to know so that I wont over heat the processor or give it too much voltage.Īfter a little while trying to find a stable overclock, i settled with 3.0GHz. For instance, with this processor, the nominal voltage is 1.05-1.3V, default multiplier is 13, default core speeds is 200MHz, and the MAX temp is 61 degrees Celsius. Before you overclock you should read all of the specifications about the hardware, just to know what limitations it may have. Overclocking is dangerous for the particular hardware which you are overclocking, whether it be your CPU, GPU, or memory. For those readers who may not know what overclocking is, it is basically tricking your CPU to think that it is faster and then will try and perform at those speeds. Being part of the Black Edition family, the AMD Phenom X4 9950 has an unlocked multiplier and FSB, which will allow the user to achieve an overclock. ![]()
