G.Skill F2-6400PHU2-2GBHZ

G.Skill Company, the Taiwanese manufacturer of overclocker’s memory modules, cannot boast being as popular as the grands of the market like OCZ and Corsair. However, they are working really hard on winning the users’ hearts, and one of the things they are doing – participating in numerous test sessions and comparisons.

Today we would like to introduce to you G.Skill F2-6400PHU2-2GBHZ DDR2-800 SDRAM kit that includes two memory DIMMs, 1GB each. According to the official specification, this memory should work with 4-4-4-12 timings and 2.0V-2.1V Vdimm.

The exterior design of G.Skill memory modules is pretty common. They are covered with standard black-anodized aluminum heat-spreaders with a company logo and identification sticker on top of them. This sticker reports the product part number, memory capacity of the DIMM, default latency settings and recommended voltage.

The SPD of G.Skill F2-6400PHU2-2GBHZ memory modules contains pretty standard set of data:

As we see, the manufacturer declared two work modes to ensure maximum compatibility of their solution. These modes are: DDR20533 with 4-4-4-13 timings, and DDR2-800 with 5-5-5-18 timings.

The chips used in G.Skill F2-6400PHU2-2GBHZ are made by Elpida. This certainly has its influence on the test results we obtained. First of all, you should keep in mind that you have to push the Write Recovery Time and Row Refresh Cycle Time timings to the limit if you want to get the memory modules built on these chips to work at their maximum frequencies. Luckily, these particular timings do not affect the performance that much.

I have to say that I was slightly disappointed with the maximum working frequencies, when G.Skill F2-6400PHU2-2GBHZ memory modules remained stable. Against the background of the results obtained from Micron based DIMM modules, they are somewhat low (all the tests were run at 2.1V Vdimm).

G.Skill F2-6400PHU2-2GBHZ modules run slower than the competitors based on Micron chips with 3-3-3-10 timings as well as with 4-4-4-12 timings. It makes no sense to set the timings to even less aggressive values, because in this case the frequency potential of the modules will get worse. And even raising the voltage significantly will not help in this case.
