Nvidia Geforce 7900 cards are very overclockable

90 nanometre baby rocks up to 710MHz

WE learned that many manufacturers will overclock the stock 650MHz Geforce 7900 GTX cards. The cards are at the various labs and Nvidia partners are working on their final clocks.


Everyone wants to clock those cards to 700MHz and some of the partners might actually be able to do it, ship it and to support the warranty at such a high clock speed.

The magical overclocking number is 710MHz and the guys who tested it could not go more than that. The cards are throttling at 720MHz and that's as high as you will reach with air.

This is roughly as much as you can overclock ATI X1900 XTX cards with an air cooler, but as you know those cards can reach a gigahertz if you cool them with dry ice or some other crazy technique. 700MHz or just a little bit higher could be a limitation of the 90 nanometre cards. We reckon that 700MHz Geforce 7900 GTX can give X1900 XTX a run for its money, but it is only a week before Nvidia officially announces it.
