Over the course of this article, we’re going to cover the bases of memory timings at DDR2-800 using our favoured Core 2 Duo processors: the E6400 and E6600. Both the E6400 and E6600 look to be right in the sweetspot of Intel’s line up at £182 and £252 respectively. They also represent both the 2MB and 4MB L2 cache versions of Core 2 Duo too, so it should give you an idea of what to expect from tweaking memory timings on all of the current Core 2 Duo processors.
This is a pretty in-depth look at timings on the Conroe specifically. The results are nothing amazing, but timings do indeed seem to make some minor differences in some tests. Will it be worth the extra cash to splurge for memory with tighter timings? Maybe not.
