EVGA’s P55 SLI achieved the highest memory speeds of any board we’ve tested to date, making it the best choice for pushing today’s RAM to its limit.
Intel’s Core i7-870 and Core i7-860 are the only LGA 1156 processors to support DDR3-1600 at stock base clock, giving these the flexibility to reach beyond DDR3-2400, without pushing past the base clock stability limit. Our sample came straight from the manufacturer.
Because some CPU clock change is required to exceed DDR3-1600, the only fair way to analyze memory performance is with a memory-only test. Sandra 2010 provides the bandwidth results.
