Re: I am more curious as to how AMD is doing with it's 1GHz vw. Al process... The Athlon is not shown at its best when pushed by increasing the FSB only, (it's better to increase the multiplier). A (typical?) 850 runs 950 without a problem with an overclocked FSB. gamersdepot.com From an overclockers standpoint, the Athlon 850 represents a speed freaks dream come true. Using the ASUS K7M mainboard, we cranked the bus speed from the standard 100Mhz up to 112Mhz which gave us a speed of 952Mhz using traditional cooling methods (Fan&Heatsink). This is largely due to the .18 micron process that the 850 is made upon. Smaller size means less heat, in fact even at this speed the chip ran cooler than our 700Mhz Athlon which is built on a .25 micron. The overall stability of this CPU, running on the Viper 750 Chipset, cannot be overlooked, and we're confident that we'll see the same on the newer KX 133 mobo's. In fact, the KX133 might well have gotten the chip beyond 1GHZ... (using a supposedly 500MHZ Athlon) ...I used a GFD to put the CPU at 600MHz and used the 105, 110, and 115MHz memory bus speeds without a hitch. I tested thoroughly with some multiplayer Quake Arena to make sure it could handle a stressful load. Then I continued at 1MHz increments and was fine until I got to 120MHz. It would not post after that, yet stability was fine all the way to 119MHz. I knew the problem was not the CPU because I have been running it at 750MHz with no problems. I decided to swap out the PC100 CAS 2 ram and try the PC 133 CAS 3 ram instead. It still would not boot after 119MHz. I was very impressed by as high as it would go with stability. The Asus K7M would only work stably up to a 112MHz bus speed, and both boards had a stepping 6 Northbridge. It may be that the Shiner reference design is the cause of the increase. slota.com Interpret this information as you will. I'm not 100% certain what to think myself, but it does look as though 1GHZ Athlon on aluminum is quite likely available now. Dan
