The controller supports PC66, PC100 and PC133 SDRAM, VCM SDRAM, as well as PC1600 and PC2100 DDR SDRAM. For the unbuffered SDR/DDR modules 6 memory banks with possibility to install up to 3 GBytes are supported (3 double-side memory modules with 16 512Mbit chips allow to reach such a volume), and for the Registered SDR/DDR modules 8 banks with up to 4 GBytes are supported. The ECC support allows to correct single-bit and to reveal multi-bit errors, what is important for highly reliable systems. When SDRAM is used usual modules easily get on with VCM, moreover, the controller allows to set timings for each bank separately.
