SimHQ’s recent look at AMD’s new AM2 socket saw the introduction of support for DDR2 memory for the company’s Athlon 64 AM2 lineup. Continuing the design of embedded memory controllers, AMD’s new family of dual-core processors work with DIMM speeds up to PC6400 (DDR2/800). Yet DDR2 has lagged considerably behind DDR in memory timings, with Cas4 being the lowest production latency available for DDR2/800. With the announcement of Corsair’s TWIN2x1024-6400C3, the company has introduced the first 800MHz (PC6400) speed grade capable of running with a latency of C3. Today’s article will examine what overall performance impact an AM2 CPU may see with lower latency memory installed in SimHQ’s benchmark suite.
