Corsair Dominator TWIN3X2048-1800C7DFIN G DDR3 Memory Kit

Overclocked Performance


For our next set of numbers, we focused on the maximum stable overclock of the TWIN3X2048-1800C7DFIN G memory kit while set to its rated timings.  Using the same Core 2 Duo E6750 CPU, we raised the Front Side Bus speed while concurrently lowering our processor's multiplier.  We tried to keep the CPU's clock speed as close to the same speed as possible for each kit tested.  For these tests, we also locked the PCI Express clock to 100MHz, raised the CPU voltage to 1.4v, lowered the CPU multiplier to 7x or 8x, and kept the memory voltage to 2.2v for all of the kits.

Ultimately, we ended up with different settings for each kit, which was unavoidable.  Here is the exact breakdown of how each kit fared in the overclocking tests:


As you can see, we have an approximate 540MHz swing in CPU frequency between the kits.  As for the memory frequency, the Corsair TWIN3X2048-1800C7DFIN G kit topped out at over 2.0GHz, which is impressive indeed.  Please keep in mind, these speeds were attained at each kits default timings.  Had we raised (or lowered) the CAS latency for each kit here, their peak overclocked speeds would likely have been different.

Raw Bandwidth

At its overclocked speed, nothing could touch the Corsair TWIN3X2048-1800C7DFIN G kit.  SANDRA reported peak bandwidth of almost 9.4GB/s and the latency benchmark came in at 60ns, which was the lowest of the bunch.
