Testing Participants: 4GB Dual-Channel DDR3-1600 SDRAM Kits

Aeneon XTUNE AXH860UD20-16H-K-4G

The memory modules sold under Aeneon brand name are manufactured by Qimonda. It is an excellent recommendation already for those who “know their way” around memory products, because Qimonda Company is one of the leading DRAM chip makers. So, they are selecting the best chips for their brand name enthusiast products, which determines the exclusivity of Aeneon XTUNE solutions.

In our today’s article we decided to line-up all products participating in the test session in alphabetical order, therefore, we had to put the Aeneon XTUNE AXH860UD20-16H-K-4G description in the very beginning. And unfortunately, it may not give you the best opportunity to notice the uniqueness of this solution, best seen against the competitors’ background. These are the only memory modules designed to work at 1.5V voltage – the nominal voltage setting for DDR3. In other words, while most overclocker memory makers increase the voltage in order to improve the chips overclocking potential, Qimonda uses an absolutely “honest” approach: Aeneon XTUNE memory works at 1600MHz at the voltage level defined by JEDEC specification.

However, you shouldn’t be misled by the fact that Aeneon XTUNE memory modules work at high frequencies and low voltage. The peculiar thing about the memory chips used for them is that increasing the voltage doesn’t improve their overclocking potential. Therefore, do not expect this memory to conquer unattainable frequencies once you push its voltage setting up: the maximum frequency we managed to achieve during our overclocking experiments with different voltage and timings settings was even lower than what we could squeeze out of DDR3 memory with 1.8-1.9V nominal voltage.

Aeneon XTUNE AXH860UD20-16H-K-4G kit ships in standard clear plastic packaging. The memory modules look quite common. Their only peculiarity is the blue PCB. The heat-spreaders used to dissipate heat from the chips are common stamped aluminum plates of black color with Aeneon and XTUNE logos on them.

The manufacturer mentions the following specifications for their Aeneon XTUNE AXH860UD20-16H-K-4G kit:

  • 2 DDR3 SDRAM modules, 2GB each;
  • Frequency: 1600MHz;
  • CAS Latency – 9, timings configuration: 9-9-9-28;
  • Voltage: 1.5V.

Note that the manufacturer puts only the frequency and the key CL value on the modules themselves.

I also have to say that compared with what other memory makers have to offer, Aeneon XTUNE modules also feature comparatively high latencies, which must be determined by the low voltage. Therefore, Aeneon XTUNE AXH860UD20-16H-K-4G should be considered an exotic product that may be of interest only in some particular cases. For example, if a mainboard doesn’t allow increasing the DIMM voltage, or if low power consumption and no heat dissipation matter the most. Luckily, Qimonda has no intention to make a profit out of exotics lovers and offers their memory kits at even lower price than any other “mainstream” DDR3-1600 SDRAM.

Memory modules SPD have been pretty sloppily programmed for DDR3-1333, DDR3-1500 and DDR3-1667 frequencies. The nominal mode is only available to you in XMP profile, however the voltage setting there is increased.

So, those users who decided on Aeneon XTUNE AXH860UD20-16H-K-4G memory kit will have to correct the memory subsystem parameters manually in the BIOS Setup.
