We got our first look at Shuttle's "flexible fuel" mobo back last November at Comdex, where the board was ensconsed behind glass in the Shuttle booth. The display made it clear the board would take both PC133 SDRAM and DDR SDRAM, which, Shuttle reps assured us, would be great for upgraders.

Of course, all I could think was: comparison review.

What better way to test the merits of DDR SDRAM versus PC133 than to test a board that could run both types of memory? Now, many months have passed, and DDR products are finally becoming widely available. And we have here a review of Shuttle's AV32, a hybrid DDR/PC133 board for the Pentium III and its ilk. As you might expect, we'll be reviewing the AV32, but we'll also let it serve as a kind of test mule for Via's Apollo Pro 266 chipset. I think that's appropriate, really. Keep reading, and I'll show you why.
