Benchmarking - AIDA64:

Because there is a lot of system tweaking that goes along with clocking up memory to non-standard speeds, we haven't included a lot of "real world" benchmarks.  Often, in order to get the memory to run at speeds other than 1066MHz, 1333MHz, or 1600MHz, 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.

With that being said, the new Sandy Bridge Core i5/i7 platform has a native 1333MHz memory controller and many motherboards have options that allow you to change the memory multiplier to achieve fast memory speeds (up to 2133MHz on the P67A-UD3 from Gigabyte) without overclocking the CPU or bus.  This will allow us to show how simple memory speed improvements affect total system performance...or how little the affect performance.  The results are below.  First up is AIDA64 (formerly known as Everest).

When it comes to memory performance in AIDA64 - the higher number the better in terms of read/write/copy and lower latency numbers are better.  You can see that the stock clock speeds at CL9 lag behind other memory settings with tighter timings, but in the end, the Viper Extreme Division 2 kit certainly edges on the G2 kit in most of the tests - except for the AIDA copy test.  The G2 memory seems to edge out the Viper Extreme - probably because the G2 timings of 9-9-9-24 trump the 9-11-9-27 of the Viper Extreme in this situation.  Ultimately, the OCZ kit clocked in at 2133 CL10 takes the cake in almost everything.

 

The other two tests are Cinebench and SuperPi.  We used SuperPi to calculate Pi to 1 Million decimal places using different memory speeds to see if memory speed affects programs that are largely CPU dependent.  The results pretty much speak for themselves.   Cinebench 11.5 was used in both CPU rendering as well as GPU / OpenGL modes to see how memory speed affects workstation performance.  I was surprised to see CPU scores stagnate while OpenGL score improved as the memory became faster.

SuperPi scores stayed pretty consistent regardless of the speed.  It is interesting that the Patriot memory at overclocked speeds showed better performance than the OCZ kit we reviewed recently.  Still, the times ranged from 10.597 seconds to 11.138 seconds at the other end of the spectrum.  There was just over half a second to be gained across these tests with equates to about 5% performance difference from the best to the worst.  Combined with margin of error around 3-5% - there is nothing much to be gained.

Cinebench told a slightly different story.  In this test, the Viper Extreme Division 2 kit end up winning in both CPU and OpenGL tests.  Even with other kits clocked faster, the timings and settings of the kit running at 1953MHz won out over the OCZ kit as well as everything else.

 

Final Thoughts:

While the Patriot P67 Optimized kits don't appear on the shelves with stellar specifications, the truth is - they are pretty solid kits.  The CL9 timings on a DDR3-1600 kit will probably make a few enthusiasts choose something else, but from what we've seen, it performs like a trooper in our test suite of both synthetic and real-world performance.  The DDR3-1866 Viper Extreme Division 2 kit also has some pretty relaxed timings, but it manages to out-perform other faster memory in the same tests.  It seems that the timings chosen by Patriot work well on the Sandy Bridge platform.  My only complaint was the poor overclocking performance of these kits.  Tighter timings on the Viper Extreme kit were not possible at all, while we only managed a 266Mhz increase in clock speed on the DDR3-1600 kit.  Traditionally, DDR3-1600 kits offer a lot of overclocking headroom; the Patriot kit was mediocre at best.

Pros:

  • Competitive pricing on both of these kits
  • XMP profiles that run at 1.65v
  • Run rock stable - even with mild overclocks

 

Cons:

  • Mediocre overclocking potential
  • DDR3-1866 kit could not run at CL8

I'd like to thank Patriot for sending us a couple sets of "Sandy Bridge" optimized memory for us to check out.  It performed better than I thought, but there is always room for improvement.  Still, it's a pretty solid bunch of memory.  If you have any questions or comments, please post them at the "Comments" link below.
