The Memory Translator Hub (MTH)
We’ve mentioned before that the i820 chipset does support SDRAM but the support unfortunately does not come without its costs. In order to support SDRAM on an 820 motherboard a fourth hub must be added to the design, the Memory Translator Hub, or MTH for short.
This MTH allows for the presence of SDRAM DIMM slots on 820 boards but the performance won’t be up to par with SDRAM + BX combos, not to mention that this will obviously raise the price of a motherboard just to gain SDRAM support.
It is very clear that the i820 chipset was intended for use with RDRAM only, however, according to Intel, PC133 SDRAM support is coming in "a future chipset." Take that for what it’s worth, but it seems like Intel has something else up their sleeves.
