Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_36528 ( "HyperTransport version" real, "Year" real, "Max. HT frequency" text, "Max. link width" text, "Max. aggregate bandwidth (bi-directional)" text, "Max. bandwidth at 16-bit unidirectional" text, "Max. bandwidth at 32-bit unidirectional*" text )

### Question ###
What Hyper Transport version has 22.4 gb/s of Max. Aggregate bandwidth?

### Accurate SQL ###

SELECT "HyperTransport version" FROM table_36528 WHERE "Max. aggregate bandwidth (bi-directional)" = '22.4 gb/s'
