amazon RAM G.Skill Ripjaws-Z PC3-12800 kit 16GB reviews
The sleeker 2.4 GHz clock speeds up to 16GB, G.Skill Ripjaws-Z F3-19200CL11Q-16GBZHD is the perfect choice to “perfect” a high-performance configuration.
DESIGN
The Ripjaws-Z 16GB (F3-19200CL11Q-16GBZHD) kit is part of G.Skill’s high-end line of RAM, including 4 2400MHz DDR3 memory bus (PC3-19200), well compatible with dual-core motherboards dual channel and quad-channel.
Compared with the popular RAM, G.Skill Ripjaws-Z 16GB kit is a “dash”, two pieces of heat dissipation on the side of the thick, gives a sense of solidity and heat dissipation efficiency.
Unlike the “dual channel” RAM kits that come with only a set of cooling fans, the G.Skill Ripjaws-Z kit comes with two heat sinks (two 50mm fans) corresponding to four quad-band (quad) -channel of the X79 Express motherboard.
Similar to some of the RAM lines designed for regular computers, the Ripjaws-Z 16GB kit does not include ECC (error-correcting code). Ball Grid Array (BGA) memory chips are capable of up to 50% less heat dissipation than previous Thin Small Outline Package (TSOP) packaging. In addition, the RAM kit is equipped with an SPD (serial presence detect) chip that supports XMP (extreme memory profile) technology. Test Lab easily pushes the bus clock up to 2,400MHz with just a few simple settings in the BIOS.
PERFORMANCE
Testing on the Ivy Bridge platform with the Gigabyte GA-Z77X-UD3H BMC, Intel Core i7-3770K processor and integrated graphics HD Graphics 4000 to demonstrate the impact on overall system performance when changing the clock SHADY. The tests include PCMark 05 and AIDA64 Memory Benchmark which measures read, write, copy and PCMark 7 performance. Results are calculated based on averages plus 5 runs.
With the default setting of the BMC, the Test Lab found that the Ripjaws-Z RAM F3-19200CL11Q-16GBZHD RAM kit operated at 1,600MHz, 11-11-11-28 timing, 2T delay; Pretty high compared to some other RAM kit.
However, these values are for reference only because each RAM kit is usually optimized for a specific clock frequency; For example, the G.Skill Ripjaws-Z 16GB kit is clocked at 2.400MHz, with basic timing values of 11-11-11-31-2T (CL, tRCS, tRP, tRAS and CMD) and a voltage of 1.65V. At other clock frequencies, readers can tweak, changing default values so they work better than the default.

Specifically with AIDA64, the read speed reached 17,906MB / s, recording 19,480MB / s and copying 20,975MB / s. Using PCMark 05 checks RAM access speed with 16MB of sample data, read speed of 19.559MB / s, write at 18.209MB / s, copy at 17.949MB / s and random access number (In seconds) is 32.4 MAccesses / s.
With the overall evaluation tool system performance is PCMark 7, Ripjaws-Z kit 16GB reached 5,721 points.
By activating the XMP mode and pushing the clock to 2.400MHz, the basic timing indicators of the RAM kit are 11-11-11-31 and the delay (CMD) is 2T; Lower than the HyperX predator Kingston KHX24C11T2K2 / 8X Test Lab ever tested.
Thus, it can be seen that the RAM kits have the same bus, the basic timing values will significantly affect the data access speed of the RAM kit. Specifically with AIDA64, the read speed reached 21,611 MB / s (up 20.69%), recording at 20,520 MB / s (5.34% increase) and copy at 24,505 MB / s (up 16.83%).
The PCMark 05 score also increased 17,75%, 6,15%, 13,51% and random access to 40,2%. MAccesses / s.
With PCMark 7, which evaluates the impact of the system on RAM changes, Test Lab found that the overall performance of the test configuration increased by 1.22% and that of the component tests were also higher than little bit.
