Which chipsets supported 512MB PC133 modules?

I know the i810/i815 only supported 256MB PC133 modules. Ditto for the 440BX (that was only PC100 to make it worse). I don't remember the early VIA cheapsets for the first generation of Athlon (KT133 and KT133A). I'm pretty sure that VIA Apollo Pro 133T also supported 512MB sticks.

I have two 512MB PC133 modules coming in and I want to know what I can use to verify their defectivelessness (ie - run Memtest and Goldmemory).

As I recall the issue with large DIMM support on 168-pin memory was usually called "Double-Sided Memory" support. A lot of the less expensive 256MB modules available in early/mid-2001 were double sided and therefore only worked with some AMD systems. KT133As certainly worked; my first PC with 1GB RAM was an Abit KT133A system.

Both 512MB sticks I'll receive are double-sided. The only thing I have so far to test them is a white-and-violet Compaq box with a VIA chipset that I still haven't identified (given by a customer who upgraded).
