G.SKILL Ripjaws X 8GB DDR3 1600MHz memory kit
The memory kit comes in traditional plastic package with transparent top. The front features large letters indicate that the product belongs to “Ripjaws X” series while small ones say the kit is intended to be used on Z68 and P67 platforms with 2nd generation of Intel Core processors.
The package also allows you to examine the modules and its part numbers. In our case it’s F3-12800Cl9F-8GBXL. The back of the package contains some marketing info. Overall the delivery box is quite simple which makes the final cost of the product lower.
Inside you find two memory modules each of 4 Gb. Both are enclosed into red heatsinks of “Ripjaws X” series. These aluminum made rads are to reduce chip temperature while overclocking and to give modules a nice finished look at the same time. The heatsink have small stickers revealing the specs of the supplied RAM modules:
- Part number: F3-12800Cl9F-8GBXL
- Clock: DDR3-1600 (PC3 12800)
- Timings: 9-9-9-24
- Capacity: 8GB (4GB x 2)
- Voltage: 1.5 Volts
- Support of XMP profiles
- Lifetime warranty
As you see, the heatsink is not tall (just 40mm) and should not interfere with massive CPU cooling solutions.
Under the radiator we notice black 6-layered PCB and 8 memory chips on each side of the module. For this kit G.SKILL uses Hynix chips with the following marking H5TQ2G83BFR-H9C. The chips are made using 44nm process technology.
The datasheet says the chips can run at voltage up to 1.575 V. On the other hand H9 chips are specified at 1333 Mhz with 9-9-9 timings. Considering G.SKILL guarantees these memory modules to run at 1600 Mhz, there could be some chip binning to ensure memory stability at higher clock. Will it effect overclocking we will find out later.
Meantime let’s see what SPD information is provided by CPU-Z tool:
More details of memory SPD profiles is provided by AIDA64 (former Everest) software:
You can notice that SPD profiles for both tools don’t quite match. For example, AIDA64 does not show JEDEC profile with 833 Mhz clock presented in CPU-Z. The XMP contains only specs which are default for this kit — 800 MHz, CL9-9-9-24, CR2, 1.5V.
