Own a Clarkdale? Choose your RAM carefully.

X-bit Labs wanted to see what the integrated memory controller on Clarkdale chips is capable of and so tested it with RAM at speeds of 1333MHz, 1600MHz and 2000MHz with two different timings at each speed. As it turns out, the difference in performance between the three speeds was rather small, while the price of RAM kits rises noticeably. When they tried overclocking the Core i5-655K the results became more interesting and rather damning for the 1600MHz kit. Their findings should be of interest
for anyone looking at buying, or who already owns a Clarkdale based processor.
"The memory controller of the dual-core Clarkdale processors is seriously inferior to the integrated memory
controllers of other Intel processors in terms of pure performance. We decided to check if there is a way to fix this
situation by using overclocker DDR3 SDRAM."
