Notes:
*This table contains preliminary information, which is subject to change.
1. Absolute maximum pin capacitance for an AGP-compliant component input is 8 pF (except for CLK) with an exception granted to
motherboard-only devices, which could be up to 16 pF in order to accommodate PGA packaging. Generally, this means that com-
ponents for expansion boards need to use alternatives to ceramic PGA packaging—that is, PQFP, BGA, etc.
