It is pretty hard to make any definite conclusions based on the obtained results. Nevertheless, we can undoubtedly say that choosing RAM for an LGA1366 system is a very versatile task. On the one hand, memory speed and timings do not have any serious effect on the LGA1366 systems performance. Things have barely changed here compared with the previous generation systems. Namely, DDR3-1600 SDRAM working in an overclocked system provides just a slight performance increase over the slower memory working at 1200MHz. Memory timings have the same insignificant effect on performance. Moreover, additional tests showed that Core i7 processors may do just fine even with dual-channel memory subsystem: the performance will drop just a tiny bit in this case.
At the same time, I am sure there will be some enthusiasts who will disagree with the conclusions made in the previous paragraph. This particular group will be the main users of high-speed triple-channel memory. So, if the performance difference between the today’s testing participants is crucial for your needs, then triple-channel DDR3-1600 kits will be a perfect choice for you. Memory modules working at this frequency give you a lot of flexibility during overclocking and do not require any significant voltage increase of the CPU Uncore. Moreover, overclocker DDR3-1600 may prove very effective with aggressive timings at lower operational frequencies.
One of the solutions that can become enthusiasts’ choice is the 6GB Corsair Dominator TR3X6G1600C8D kit we have tested today, which is available in retail freely. At the same time, we are not ultimately impressed with this particular solution, because other memory makers can currently offer somewhat better timings combinations at the same price. Besides, the massive cooling system topping these memory modules may cause some problems during system assembly if there is a large CPU cooler involved.
In conclusion I would only like to add that the need to install 6GB of DDR3-1600 memory into systems from the high-end price segment rests on pretty shaky ground. Practical experience and common sense suggest that this amount of memory is way too big. Triple-channel 3GB kits, like Corsair Dominator TR3X3G1600C8D, or even dual-channel kits of two 2GB modules requiring not very high voltage settings may be a smarter and more justified choice in this case.
