G.Skill RipjawsxG.Skill, the makers of some of the most sought after memory on the planet, was kind enough to send over a version of their low voltage memory kits aimed at the Cougar Point chipsets. The sample kit they sent over heralds from their famous RipjawsX line and is rated at 1.5 volts operating at 1866MHz. Specifically, ours is model F3-14900CL9D-8GBXL, consisting of two 4GB modules for a usable total of 8GB. Read on and find out how these perform.

Introduction to the G.Skill DDR3 RipjawsX 1866MHz Memory

With the introduction of the Cougar Point P67 and Z68 chipsets brought on a new era in system memory. The need for low voltage made life easier on the integrated memory controller of the Sandy Bridge processor. Was the need for low voltage memory a much needed one? Not at all. Usually, the standard 1.65 voltage we saw with the P55 and X58 would work just fine in these new systems. Lower voltage RAM just made compatibility much easier to deal with.

Closer look

Before we get into the details of the visual aspect of the RipjawsX, we will go over the operating aspects of the kit. It begins with the low voltage requirement of 1.5 volts. In order to obtains this is a very low operating voltages, the timings of 9-9-9-24 were necessary for the 1866MHz operating speed. We stated in the beginning the use of low voltage memory is due to the Sandy Bridge processor and we have not changed our thinking on that fact. But AMD fans will get a performance boost out of the high operating frequency when using either the Llano or upcoming Zambezi platforms, as both support 1866MHz natively.

The RipjawsX family consist of twenty-five different variations ranging from 2GB kits all the way up to 24GB Triple Channel ones. The timings can get freakishly low at CAS 7 to a much looser CAS 9. Even more impressive would be  the max frequency they are available in, with the king of the hill F3-20000CL9D-4GBTDS kit coming in at an amazing 2500MHz.

The modules are wrapped in an all aluminum heat spreader that looks much different from any of the other company’s spreaders we have reviewed. The spreaders measures slightly over 1.5 inches tall, make life a little easier for mounting larger CPU heat sinks by giving a little bit more clearance.

One side of the modules has the G.Skill trademark along with the RipjawsX logo. The reverse side has the product information sticker on it. The sticker indicates the frequency, timings, voltage and other miscellaneous information about the modules.

Overclocking

Like much of the G.Skill kits I have had the pleasure of using over the past few years, all have had some extra room left in them for overclocking; this kit is no different. It is known that the P67 chipset is safe for continual usage with DIMM voltages up to 1.65, so this is where we set our voltage at in the BIOS of the system. Timings were left alone to see if the system would post with the frequency increased to 2133MHz. We had partial success with this as the system did boot, but was not stable using each of the benchmarks. We then played with the timings and loosened them a hair to 9-11-10-28. With this change we had complete success.


Testing Results

AIDA64 Extreme Edition 1.50
FinalWire Ltd. today announced the immediate availability of AIDA64 Extreme Edition 1.50 software, a streamlined diagnostic and benchmarking tool for home users; and the immediate availability of AIDA64 Business Edition 1.50 software, an essential network management solution for small and medium scale enterprises. The new AIDA64 update implements AVX-optimized benchmarks for the upcoming Intel Sandy Bridge processors, adds a brand new video encoding benchmark, and supports the latest AMD and nVIDIA graphics processors.

SiSoftware Sandra
We are pleased to announce the launch of SiSoftware Sandra 2011, the latest version of our award-winning utility, which includes remote analysis, benchmarking and diagnostic features for PCs, servers, mobile devices and networks. A year ago, SiSoftware released Sandra 2010 with full support for Windows 7; in the 18 months since the launch of Windows 7, more than ever before we have seen the line blur between PC and entertainment hubs. Two months ago we released a Blu-Ray benchmark, now we have added a brand-new Media Transcoding benchmark using the new Media Foundation of Windows 7. We have also added yet another benchmark (GP Cryptography) which allows direct comparison of CPU performance (using crypto instruction sets) and GPGPU/GPCPU/GPAPU performance.

Super Pi Mod1.5 XS
In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo. The program was written by D.Takahashi and he collaborated with Dr. Y.Kanada at the computer center, the University of Tokyo. This record should be the current world record. (Details are shown in the windows help.) This record-breaking program was ported to personal computer environment such as Windows NT and Windows 95. In order to calculate 33.55 million digits, it takes within 3 days with Pentium 90MHz, 40MB main memory and 340MB available storage.

PassMark Performance Test
PassMark Software has delved into the thousands of benchmark results that PerformanceTest users have posted to its web site and produced five Intel vs AMD CPU charts to help compare the relative speeds of the different processors. Included in this list are CPUs designed for servers and workstations (Intel Xeon and AMD Opteron processors), desktop CPUs (Intel Core2 Quad, Intel Core i7, Intel Core2 Extreme and AMD Phenom II processors), in addition to mobile CPUs.


Conclusion

The G.Skill RipjawsX 8GB DDR3 kit is a great performer no matter which class you fall into: novice, gamer or enthusiast. But please, do not just take our word for it; check out the benchmarks we ran. The need for 8 gigs of memory is rapidly growing and G.Skill recognizes this, providing the end user with awesome performing kits and at respectable prices.

Intel made the Sandy Bridge processor very easy to overclock, which in order to do so you only have real access to the CPU multiplier, and little in the way of BCLK. So we have to get all the performance we can with what we have. This leaves overclocking the RAM we were sent, and upgrading to a solid state drives (which G.Skill also manufacturer).

This particular kit was able to achieve 2133MHz with very little effort. A bump in voltage to 1.65v from the default 1.5v and loosening timings slightly to 9-11-10-28 was all that it took. Some may frown on looser timings, but if you look at the performance numbers you'll notice there is not much being sacrificed.

Another thing that we love about this kit is the heat spreaders which are cool (pun intended), and good looking. These kit would look great say on the ASUS Maximus IV Extreme. Better yet is their short height which offers up some nice clearance, and that leads to not having as many issues when mounting those large CPU coolers.

This kit goes for $64.99 at Newegg at the time of writing. Not a bad price with the way prices are downing on DDR3 kits.
