Benchmarking the DDR3-1333 Kit

Benchmarking - Everest:

Because there is a lot of system tweaking that goes along with clocking up memory to non-standard speeds, we haven't included any "real-world" benchmarks.  In order to get the memory to run at speeds other than 1066MHz, 1333MHz, 1600MHz or 1866MHz the motherboard bus and CPU must be clocked up in order to achieve these speeds.  As we've shown before the CPU plays a huge roll in benchmark performance and so it's not fair to compare WinRAR compression when the CPU is clocked up 400MHz faster.  Of course the "RAM" will look faster, but in reality the CPU is the one doing the work.  For this reason we use two simply synthetic benchmarks to show memory performance.  How it affects performance in the real-world will depend largely on CPU, motherboard and other hardware bottlenecks so we have to be content with synthetic benchmarks to gain our number metric.  First up is Everest.


While it's no surprise that the Crucial DDR3-1600 crosses the finish line first in some of the tests (stock, fastest low latency, fastest stock timings), the Corsair pulls off a very impressive showing and we rechecked our numbers several times.  ll in all, at the fastest speeds both kits are capable off, the Crucial wins, but it's pretty darn close in other areas.  This shows that when we are running at DDR3-1496 at CL8 on the Corsair kit vs. DDR3-1600 CL8 on the Crucial kit, the CPU plays a role as the Corsair system is overclocked.

Benchmarking - SiSoft Sandra:

If you want to compare your triple-channel DDR3 performance, you can head on over and grab SiSoft Sandra here and compare away.  Please keep in mind that if you are using a dual-channel kit, your performance numbers will look dismal.

SiSoft shows a greater benefit to faster memory than Everest did.  The fastest numbers that Corsair managed to pull off was at 1734MHz at CL9.  This kit pulled off a theoretical 24.64GB/sec transfer - compared to the best the Crucial DDR3-1600 kit did at DDR3-1808 at CL8 - 30.2GB/sec.  The difference won't likely be noticeable in most situations, but the impact on your wallet certainly will be noticed.  The Corsair kit will save you well over $200.


Final Thoughts:

Running This is our second official Triple-Channel kit of DDR3 to hit the bench here at BCCHardware and we have limited data on other kits.  In fact, the Corsair DDR3-1333 kit is pretty much the opposite end of the spectrum, but that's what makes this review so interesting.  Although the Corsair kit is $230 cheaper than the 6GB Crucial DDR3-1600 kit, the performance difference isn't that significant.  The performance of this kit seems to be very solid and we actually managed to run well over stock speeds at tighter timings making this a great value.  This is probably one of the cheaper triple channel 3GB kits of DDR3 and it manages to hold it's own against more expensive PC3-12800 CL8 kits.  This gives the kit a perfect score in terms of "value".  Overall, this is a great kit and if you are building a system and have spent all of your money on motherboard and processor.  You still can have very good performance without spending a crap-ton of money on RAM.
