GeForce 6600 GT: Noise, Overclocking, 2D Quality
The cooling system of the GeForce 6600 GT was rather quiet – the fan was noisy, but not irritating, without any disturbing shrieks. The sound of the cooler soon merged with the other system noises – from the CPU cooler, the two fans of the 550W PSU, and the HDD’s spindle – never rising above them.
The two samples of the GeForce 6600 GT we happened to have in our labs overclocked differently. One was stable at 580MHz GPU frequency, which was no record for a 0.11-micron chip. The other card, however, made an impressive climb to 625MHz. The memory overclocked to 550 (1100DDR) MHz on both samples – that’s good for 2.0ns chips, originally working at their nominal frequency.
The graphics card outputted a sharp picture on the screen in all the resolutions our monitor could support, i.e. up to and including 1800x1440@75Hz. Well, we’ve got used to that already. Only cheap no-name products, whose manufacturers save on the PCB design and output LC filters, produce a bad onscreen image. The reference GeForce 6600 GT has nothing to do with such “products”, of course.
