X-bit Labs compares 1800MHz DDR3 memory modules from Corsair, OCZ and Super Talent:
From the technical prospective, DDR3 SDRAM modules intended to work at 1800MHz do not represent anything innovative. They managed to hit a new frequency barrier solely thanks to evolutionary improvement of the technological process used for DDR3 SDRAM chips production. As a result, the new high-speed modules use the same chips as the previously discussed DDR3-1600 SDRAM. In other words, all DDR3-1800 memory we are going to talk about today is built using legendary Micron D9 chips manufactured with 78nm technological process.
So, the memory makers had only to slightly adjust the micro-chips selection procedures to be able to build DDR3-1800 solutions. Printed circuit boards and cooling heat-spreaders remained the same as those of DDR3-1600 solutions. Nevertheless, let’s take a real close look at our today’s testing participants, before we move on to the actual performance analysis.
