RAM kit DDR4-3000 G.Skill Ripjaws 4 F4-3000C15Q-16GRR (16 GB): review and testing

At the present time we cannot say that the new format DDR4 memory has become fairly widespread. But the true fact that it is worthy of close attention due to the considerable potential. First of all, the capabilities of DDR4 are appropriate in conjunction with high-end processors Intel Xeon E5-2600 v3. It is expected that such devices with 16 or 18 cores and twice the number of threads require need the additional bandwidth, which is offered by memory DDR4. For the ordinary user the format DDR3-1866 with bandwidth of 40 GB/s can be enough. Thus, if you do not aspire to turn your system into a computational monster, the purchase of DDR4 memory will be premature. In addition, at the moment there are some shortcomings in the functioning of the BIOS in some motherboards, which leads to periodic failures and irregularities in the system. It will take a little more time, and the various elements of the new platform Socket LGA2011-v3 (processor, system logic and RAM) will have a much greater harmony.

However, in sales you can find available processors Intel Haswell-E and motherboard with logic Intel X99, which are suitable only for the memory DDR4.

A significant role in expanding the range of memory modules DDR4 memory plays company G.Skill. At the time of announcement of Intel's platform Socket LGA2011-v3 and processors Intel Haswell-E the warehouses of G.Skill was a considerable number of RAM kits of standard DDR4.

The reasonableness of the business plan of the company says relatively recent advances in its lineup G.Skill Ripjaws 4. It has provided a new record of the frequency of the memory module, having overclocking it to 4004,4 MHz.

The tested model G.Skill Ripjaws 4 F4-3000C15Q-16GRR refers to the same range, and therefore, we have a quality product from a good producer.

Packaging and design of the modules

G.Skill Ripjaws 4 F4-3000C15Q-16GRR

Kit G.Skill Ripjaws 4 F4-3000C15Q-16GRR comes in a compact plastic blister of a strict design that protects the module against damage during transportation and breakdown of static charge. Inside the container is a cardboard mat with the logo of the series G.Skill Ripjaws 4 and a sticker with the logo of the company.

On the reverse side of the mat you can read small advertising copy, that expalins that memory is specifically designed and tested for maximum stability and performance on the latest platforms that support standard DDR4. This undoubtedly will be pleased by demanding gamers and people who have to deal with other voracious software. Also here is an information about a lifetime warranty for the model G.Skill Ripjaws 4 F4-3000C15Q-16GRR, however, for all the other products of the company G.Skill. Also, the small print at the bottom specifies phone numbers and e-mails where you can get technical support.

Modules G.Skill Ripjaws 4 F4-3000C15Q-16GRR have attractive and aggressive appearance, typical of most lines of RAM G.Skill. They are made on a black PCB and fully closed with beautiful black-and-red radiator. Theheight of the entire product reaches forty millimeters, so you won’t have problems with the installation even on systems with sufficient overall CPU cooler.

G.Skill Ripjaws 4 F4-3000C15Q-16GRR

The sticker on the back of the radiator carries the following information: serial number (F4-3000C15Q-16GRR), the operating frequency of the memory (DDR4-3000), the recommended timings (CL15-15-15-35), operating voltage (1.35 V) and the number and volume of each module (4 pieces 4 GB) and the production date (November 2014). Also here is the information about the support of Intel XMP 2.0.

Radiator consists of two parts fastened at the top by the stoppers firmly to memory chips, providing high quality of heat dissipation. The same function is pursued by toothed comb and slots on the back modules.

Thanks to stops it is not difficult to remove radiator from PCB will have no difficulty, however, we do not recommend to do that because in this case you will lose the guarantee. But in order to satisfy your curiosity we did it for you.

G.Skill Ripjaws 4 F4-3000C15Q-16GRR

As you can see, the layout of the modules is one-sided, i.e. all eight memory chips are soldered on one side of the PCB.

The markings on the memory chips G.Skill Ripjaws 4 F4-3000C15Q-16GRR indicates that they are produced by G.Skill. Also we’ve noticed capacity of each chip (512MB) and their serial numbers.

Technical features and operation modes

Instead of popular programs AIDA64 and CPU-Z, for the analysis of module parameters Thaiphoon Burner was used. This choice is due to the fact that the first two use the old algorithm for the interpretation of data from the SPD, which does not always work correctly, and the latter is specially designed for testing RAM. Actually, the above is a brief and detailed report Thaiphoon Burner about the technical characteristics of memory modules G.Skill Ripjaws 4 F4-3000C15Q-16GRR. Program has identified a well-known company Sk Hynix as the direct manufacturer of memory chips.

The SPD of tested modules has several working profiles, in order to avoid any problems with the launch of memory. Four of them that are compliant to standard JEDEC (DDR4-2133), memory is clocked at 1066 MHz and with delays 15-15-15-35, 16-15-15-35, 18-15-15-35 and 19-15 -15-35.

XMP-profile DDR4-3000

In addition, there is one XMP-profile DDR4-3000 MHz with timings 15-15-15-35, designed to operate under voltage 1.35 V. In our case, the motherboard automatically raised the FSB up to 125 MHz, and the multiplier of all eight CPU cores reduced to a value of "x28". Thus, CPU operated at a frequency of 3.5 GHz in the continuous mode. According to the specification Intel, Turbo Boost mode should increase the CPU frequency to a level at boot time only 1-2 cores, but it is doubtful that this is a problem for modern processors. The rest of modes, including overclocking worked with the nominal FSB frequency in mode Turbo Boost.

Testing
For testing we used the following configuration of the stand:

Motherboard

ASUS RAMPAGE V EXTREME (Intel X99, Socket LGA2011-v3, DDR4, E-ATX)

CPU

Intel Core i7-5960X (Socket LGA2011-v3, 3,0 GHz, L3 20 МB)

Frequencies DDR4-2133 MHz and DDR4-3000 MHz correspond to the preset profiles, and for speed DDR4-2666 MHz timings and voltage were chosen experimentally. Best timings were achieved at a voltage of 1.35 V.

G.Skill Ripjaws 4 F4-3000C15Q-16GRR

Let's move on to the analysis of the results. The graph shows that the transition from one mode to another one impacts is quite weak on system performance. It is at the level of a few percent. That is, it is quite difficult to notice the changes in everyday applications such as games and archivers. If we talk about the speed of memory in isolation from its daily application, the increase in the effective frequency from 2133 to 2666 MHz leads to 10 percent increase in reading speed of memory and a 19-percent increase in the speed of copying. Jump to DDR4-3000 MHz gives some increase in performance, but at the level of 1-2 percent for read and 8.7 percent for copy.

As for the comparison of G.Skill Ripjaws 4 F4-3000C15Q-16GRR with its opponent, their results are almost identical, but the model of G.Skill has a small advantage over the rivals due to lower latency.
