Overclocker of Korea managed to make the fourth core of AMD's core triads work, turning the processor into a core quadrant.
For years, it has been known that in order to meet consumer demand for cheap processors, both processors and video card manufacturers are fogging in terms of clock speed, and the cache sizes the processors and then sells the processors as a cheaper product. This is done for two reasons: the first is because the same core did not come down perfectly from the production line, so instead of throwing it away, chip manufacturers prefer to sell it as a cheaper product to a wider market segment. The second reason is that the market share of cheap products is significantly higher than that of the Extreme processors (which are made up of the most perfect cores that come down from the production line), and there are not always enough processors during production, so the chip manufacturers lock the product (or turn off several processing tubes) Cheap and then sell the chip as a cheaper processor. This is also one of the reasons that processors from a given manufacturing week differ from processors from another manufacturing week in their speeding results.
A good example would be AMD Core Triangles, No matter if it is In the first Phenom processors Or the Phenom II processors. Originally, it was in the core, but apparently the production of one core was damaged, so AMD turned it off in the factory and marketed the processor as a core triangle. The novelty is that users can probably run this kernel without making any physical changes to the processor, through the BIOS of the motherboard. In new motherboards based on AMD chipsets, Preferably 790FGX, There is a feature called ACC, which is an acronym for Advanced Clock Calibration (or in English "Advanced Clock Speed Adjustment"), which improves the system's ability to quickly move Using the AMD OverDrive software. Given that the motherboards that brought the Phenom II processors to over 6 GHz are based on the 790GX chipset, it seems that the very existence of a built-in video card in the system does not interfere with the acceleration attempts.
Before the change
: After the change
By passing the ACC function in the BIOS on the Biostar TA790GX 128M panel from Disabled to Auto, Overclocker from Korea was able to make the fourth core work. After checking the stability of the system, tested its performance using 3DMark06 and received additional 1000 points in the processor score. As you can see in the pictures, the BIOS of the motherboard did not detect the perfectly generated processor, since AMD never launched a Phenom II 3X processor that has 4 active cores. The method is not expected to work in 100 percentage of the cases, since sometimes the fourth core is really screwed up, but if activated, you earned a core square at the price of a triangle.
Another case in which it was possible to turn a cheap product into an expensive product by changing its content was to open the pipes on both the GeForce 6800 and Radeon X800GTO cards. In both cases, it was possible to open the pipes operated by the graphics core manufacturer and to make the lowest market card from the company's home to its flagship. In case of NVIDIA, Many found that 6800NU or 6800GS could be opened to 6800 ULTRA, and in ATI's case, many discovered that the X800GTO and X800GTO2 after opening pipes became X850XT.
