Philipp 6 Posted July 31, 2001 Anandtech has posted a i815 B-Step Tualatin motherboard roundup One of the biggest rumors that surrounded the Tualatin was that although it wouldn’t work on current Socket-370 motherboards, it would work on older BX motherboards. This rumor, like many others that are prevalent today, is indeed false. Looking back at our Tualatin review we mentioned that the Tualatin uses a lower voltage AGTL bus signaling than the AGTL+ FSB supported by all previous Socket-370 chipsets (1.25V vs. 1.50V). The combination of this and the fact that earlier motherboards did not have the two new pins (VID25mv & VTTPWRGD) that the Tualatin requires for proper operation results in no possibility that the Tualatin will work on older motherboards that don’t properly support the CPU.
