Overclocker usually attempt to purchase video card from lower price categories in order to raise its level speed to higher representative of this family.
Video card geForce 8600 GTS and GeForce 8600 GT in standard version are characterized by design. The printed-circuit board in geForce 8600 GT has simpler design, it is deprived from the additional power connector and completed with slower memory. In other words, the overclock Of geForce 8600 GT to the geForce 8600 GTS level is sufficiently complicated.
Associates modified two video card geForce 8600 GT - from inno 3d and Palit production . They are characterized by cooling system (Palit, equips its memory microcircuits with radiators) - Palit use formally faster memory from qimonda (Infineon) production with access time 1.3 ns. And here if video card inno 3d has core voltage 1.33 v and memory voltage 2.0v , then the palit is characterized by the increased voltage - to 1.4 v on core and 2.1 v on memory. Obviously, all these differences allow Palit video card to overclock to 723/1900 MHz, whereas inno 3d product collects only 692/1850 MHz without modifications. Let us recall that the default frequencies for geForce 8600 GT are equal to 540/1400 MHz.
Let us examine the overclock results , obtained after the volt mod:
- Inno 3d GeForce 8600 GT (1.7 v core, 2.25 v memory) - > 921/1904 MHz;
- Palit geForce 8600 GT (1.5 v core, 2.25 v memory) - > 800/1900 MHz;
- Palit geForce 8600 GT (1.75 v core, 2.25 v memory) - > 1020/1910 MHz (modified cooler ).
To get the core frequency up 1 GHz it was necessary to raise voltage and also to replace the regular cooler zalman by more effective hand-made one :
Almost 90% increase in the core frequency and 36% increase in memory frequency . Related Products :
