G.Skill Ripjaws Z DDR3 2133 8GB Quad Kit

G.Skill Ripjaws Z DDR3 2133 KitAnd with the addition of the CPU Strap allows us to take the memory bus higher in smaller increments. And this is great with you have some pretty solid memory modules. And today on tap we feel that we do have a set of memory we consider solid. The kit is from G.Skill and is called the Ripjaws Z and is rated at 2133 MHz but it would be silly to not try and take them farther.

Introduction to the G.Skill Ripjaws Z DDR3 2133 8GB Quad Kit

The X79 chipset may not be the newest chipset from Intel but it is the highest performing one as of right now. And if you have had the opportunity to play around with it in an overclocking manner you will know that the whole process is easier than some of the much older chipsets but not as easy as the P67/Z68 chipsets. This is due mostly to the addition of the CPU Strap which I am a fan of. It finally, well to a point to play more with the clock of the CPU.

And with the addition of the CPU Strap allows us to take the memory bus higher in smaller increments. And this is great with you have some pretty solid memory modules. And today on tap we feel that we do have a set of memory we consider solid. The kit is from G.Skill and is called the Ripjaws Z and is rated at 2133 MHz but it would be silly to not try and take them farther.

Closer look

G.Skill offers several different kits rated at 2133 MHz under the Ripjaws Z marker. The differences would be kit size, timings and voltages. One set has a set of red heat spreaders instead of the black we will be reviewing today. The difference is the timings which are lower at 11-11-11-30 while the rest of the series boast timings of atleast 9-11-x-x.

The official name of the set we are reviewing today is F3-17000CL9Q-8GBZH. This is an 8GB kits consisting of four 2 GB modules. The stock timings are pretty impressive at 9-11-10-28. The memory is Intel XMP certified meaning that it will adjust to these timings with the executing of the feature in the BIOS. And it will only do this properly on the Intel Z77 and X79 chipsets. Voltage-wise the kit is set at 1.65 which is at the higher level of voltage for these chipsets.

Buying an 8GB kit from a system may seems like it’s not enough. But if you really look into the situation of many people 8 GB is plenty. Not everyone is a gamer or digital artist. Then why purchase a kit that is rated at 2133MHz? Why not just settle for a 133MHz or 1600MHz kit? First of all, why settle? But some will like the slight increase in responsiveness. And plus the cost increase may not be that much.

The heat spreaders of the Ripjaws Z are not short but they are not extremely tall either. The height is just a bit taller than that of the Kingston HyperX we reviewed here.  So you run into issues with some coolers but if it just a matter of the fan sitting on top of the memory modules than a slight adjustment of the fan may solve the problem.

The modules are completely black with blue and white stickers placed in the middle. The spreaders are really fancy at all but do contain little ridges to give them a non-traditional look.

The opposite side of the modules looks pretty much the same except it does have a P/N sticker that gives details of the modules.

We spent our fair share of time trying to overclock this G.Skill. We learn a lot since our last kit and learned oven more this go around. First, we started with trying to get the most out of the CAS 9 timings of the kit. Never upping the voltage we tried different CPU Strap setting to come to this conclusion. 2198 MHZ was that conclusion. Could it get lower? Possible. But we didn’t take the kit over the rated specs.


So, what will happen if we loosen the timing just a little? At the end of the day we ended as a very respectable 2240 MHz it’s not anywhere near the magically 2400 MHz we were hoping for but we didn’t have to sacrifice timing.


AIDA64 Extreme Edition
“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.”

Super PI Modded 1.5
“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 in collaboration with Dr. Y.Kanada at the computer center. 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 a Pentium 90 MHz, 40 MB main memory and 340 MB available storage.”

Flying Wild Hogs Hard Reset
“Thee world as we know it ceased to exist. Humanity is at the verge of extinction, living in the last closed city of Bezoar. Mankind wages war against the machines controlling vast areas of what became the 'Barrens'. Machines want to control and assimilate 'The Sanctuary' a network that holds billions of digitalized human minds. Our hero, Maj. Fletcher, is a soldier of CLN - a corporation combat unit, established to protect the city. Machines are constantly assaulting the walls of Bezoar. Fletcher moves in when Bezoar's protective barrier is breached.”

Futuremark PCMark Vantage
“PCMark Vantage is a PC benchmark suite designed for Windows Vista offering one-click simplicity for casual users and detailed, professional grade testing for industry, press and enthusiasts.
A PCMark score is a measure of your computer's performance across a variety of common tasks such as viewing and editing photos, video, music and other media, gaming, communications, productivity and security.
From desktops and laptops to workstations and gaming rigs, by comparing your PCMark Vantage score with other similar systems you can find the hardware and software bottlenecks that stop you getting more from your PC.”

MaxxMEM 2
“Is the *little brother of MaxxPI², it contains the same Memorybenchmark routine as MaxxPI² does.
So your reaced results will be comparable to Memory / Latency benchmarks done by MaxxPI².”


G.Skill constantly keeps me amazed with the incredible products they put out. Visiting any large forum you will see some very impressive numbers featuring G.Skill product. This kit here may not hit 2400 MHz at CAS 10, but it did achieve 2240 MHz without having to resort to go below CAS 10. So, there is definitely value in this kit.

One thing many will nice about the kit is you don’t have to worry as much with cooler selection as you would with some other kits. With the Thermaltake Frio Extreme cooler the fans did sit on top of the heat spreaders of the kit but did not interfere with performance of the cooler at all.

The XMP function is one the easiest features to like about this kit or any other kit for that matter. It is a no-brainer when it comes to running the kit at its rated speeds. a quick trip to the BIOS and selecting the XMP option is all it takes.  There is no reason to run at a slower speed when you don’t have to.

Google shopping reveals the kit selling for as low as $73 but from a store we have never hear of. $89 from the Egg who is well known and a pretty trust online shop.
