Yes, exactly as mine was advertised!
I see they've also included the small-print on the advert, though (I had to search through online manuals) --> "Note: PC3200 Max. to 2 banks only; PC2700 Max. to 4 banks only", where PC3200 = DDR400, and PC2700 = DDR333.
So, 2*512MB DDR400 would be fine for 1GB, but 3*512MB DDR400 for 1.5GB would not be......I've got a 1GB stick and 2*512MB in mine, so it forces it all to run at PC2700/DDR333 speeds.
