CREATE TABLE table_name_79 (fsb_ht_frequency__mhz_ VARCHAR, sata VARCHAR, memory VARCHAR)

Which FSB/HT frequency (MHz) has a SATA larger than 6 and DDR 266/333/400 Registered/ECC memory?
SELECT fsb_ht_frequency__mhz_ FROM table_name_79 WHERE sata > 6 AND memory = "ddr 266/333/400 registered/ecc"
SELECT "fsb_ht_frequency__mhz_" FROM "table_name_79" WHERE "ddr 266/333/400 registered/ecc" = "memory" AND "sata" > 6
