But Intel, faced with design flaws and production delays, pushed back the releaseof the much anticipated 820 chipset to November from September, junking thousands ofmotherboards along the way. At that time, Intel also faced a shortage of Rambus memory,which still remains in tight supply. So the company had no choice but to tweak the chipsetdesign to allow systems to use SDRAM instead of Rambus memory, and the MTH was designed toallow the 820 chipset to work with an SDRAM. isHyperActive's affliated US site.
