Closer Look at G.Skill RipjawsZ F3-192000CL10Q-16GBZHD
We didn’t have to think for a long time which memory to choose for our LGA 2011 performance tests with different frequencies and timing settings. G.Skill was one of the first companies to release high-frequency quad-channel DDr3 SDRAM kits for Sandy Bridge-E, so when the company representatives offered us to test-drive their new product, we obviously agreed. So, we received a quad-channel DDR3-2400 SDRAM kit with default timings set at 10-11-10-31 and total capacity of 16 GB. As you may have already guessed, this kit consists of four memory modules, each 4 GB big.
The complete official specifications of the kit with F3-192000CL10Q-16GBZHD part number look as follows:
- Quad-channel kit consists of four memory modules, 4 GB each;
- Nominal frequency: 2400 MHz;
- Timings: 10-11-10-31-2T;
- Voltage: 1.65 V.
The modules are covered with unique aluminum Ripjaws heat-spreaders. They are of stylish black color. The kit also includes two DIMM frames with fans that should cool the modules during work. A complex cooling system like that was most likely included for marketing reasons rather than practical necessity. In reality there is no need in such powerful airflow directed towards the memory modules, because they don’t get too warm. However, we would like to give G.Skill special credit for their unique heat-spreader configuration: unlike many other memory makers, G.Skill’s shaped aluminum plates are pretty short, so they don’t interfere with the large processor air-coolers that are pretty popular these days. The total height of the G.Skill memory modules is only 41 mm:
To ensure simple installation procedure, G.Skill RipjawsZ F3-192000CL10Q-16GBZHD modules support XMP 1.3 technology. The only preset XMP profile contains all nominal timings and information about the need to increase the VCCSA voltage to 1.2 V. I have to say that to ensure that these modules can work stably at 2400 MHz, you will also need to increase the VTT voltage, but unfortunately, it is impossible to record this setting into the XMP to be adjusted automatically. Therefore, after installing this memory into your system you will need to additionally adjust the VTT voltage before you can start using it in this mode.
Most overclocker RipjawsZ modules, including the ones we got for review this time, are built with specifically selected Hynix H5TQ2G83BFR-H9C memory chips. At this time it is a pretty exotic solution, but it looks like these chips will become more popular, because as we can see, they are capable of working at very high frequencies, proving just as good as the well-known Powerchip and Elpida Hyper chips.
G.Skill can currently confirm that their memory works as DDR3-2400 on four popular mainboards: ASUS Rampage IV Extreme, ASUS P9X79 DELUXE, ASRock X79 Extreme 4 and MSI X79A-GD45. It turned out that this list is not just a formality, and on other mainboards the problems are more than likely to occur. For example, we couldn’t get these modules to work stably at the desired frequency on our ASUS P9X79 Pro mainboard: they refused to work at anything above DDR3-2133. However, there were absolutely no problems with ASUS Rampage IV Formula, and our G.Skill RipjawsZ F3-192000CL10Q-16GBZHD kit immediately took off as DDR3-2400 without any special effort.
