High-end DDR2 memory hard to manufacture

The Inquirer heard only 0.5 percent of DDR2 memory chips can achieve high clockspeeds like the recently introduced 1.11GHz modules from Corsair:
The reps told us that the Dominator series is made after an array of testing. Currently, the modules are produced after the company tests all of the received Micron chips at 800MHz and a CAS3 latency, which is only achieved by 10 per cent of all chips.

After that, the chips are tested at 1.111MHz and only five per cent of those validated chips will be able to make it into the highest-clocked modules which Corsair offers. So, we're talking about a little less than 0.5 per cent of overall chips that Corsair puts into production.

Also, the number of tested memory chips does not equate to the number of memory modules produced, as chips have to be paired together and then match the clock and targeted latency.
