After testing a kit Brand A-DATA to P55 platform oriented rather upscale, here we test kit of G. Skill 2x2GB DDR3 certified at a frequency of 1600 MHz with latencies of 7-7-7-24 fairly tight 1.6 V. It shall be the F3-12800CL7D-4GBRH DDR3-1600 PC3 12800 4GB (2GB x 2) Cl 7-7-7-24-2N 1.6V.

In this same range Ripjaws platform for P55, there are two kits:

F3-12800CL7D-4GBRM DDR3-1600 PC3 12800 4GB (2GB x 2) Cl 7-8-7-24-2N 1.6V
F3-16000CL9D-4GBRH DDR3-2000 PC3 16000 4GB (2GB x 2) CL 9-9-9-27-2N 1.6V

The chips used to form kits of 16000 CL9 are identical to those of 12,800 CL7. In France, one can find the 4 GB of 12800 CL7 and 4 GB of 16000CL9 around 100 € while the price of 10,666 CL7 is a little less than 90 €.

As its name may probably indicate the aluminum heatsink covering the memory chips like the jaws ... rather original idea from the manufacturer Tawain.

SPD

The kit F3-12800CL7D-4GBRH integrates three SPD (Serial Presence Detect) configured according to the JEDEC standard and certified to operate with a voltage of 1.5 V:

• DDR3 1218Mhz with timings of 8-8-8-22
• DDR3 1370Mhz 9-9-9-25
• DDR3 1522Mhz 10-10-10-28

This relatively low frequency and very relaxed timings to ensure compatibility with all motherboards and processors. G. Skill has also provided are kits Profile XMP (Extreme Memory Profiles), not conforming to JEDEC standards. It allows the motherboard to automatically adjust supporting strips on their official specifications determined by G. Skill. Profile XMP G. Skill F3-12800CL8 is 1600 MHz 7-7-7-24 1.6 V G.SKill has certified its kits to a maximum voltage of 1.6 V the 1.65V too close to the limit by making Intel a few times too afraid to users.
