Aeneon XTune AHX860UD20-16H-K-4G
Aeneon may be the retail brand for famed manufacturer Qimonda, but old timers will instead remember the company from which Qimonda was spun, Infineon. Today’s first set of modules are also the only parts to run full rated speed and timings at JEDEC standard 1.50 volts
The use of standard voltage means these parts don’t require any extravagant cooling solution, but the standard voltage also implies run-of-the-mill timings. Thus, rated latencies of 9-9-9-28 are not surprising for XTune PC3-12800 modules.
What is surprising is that Aeneon didn’t go by the book with its SPD timing values, tossing in both XMP and EPP 2.0 modes in addition to odd speeds such as DDR3-1500 and DDR3-1866. In fact, even though the package explicitly states that no more than 1.50 volts are needed, the rated speed and timings are only programmed with an elevated XMP voltage.
We found XTune DDR3-1600 modules ran quite easily at rated speed and timings using only 1.50 volts, just as the package stated.
Using two AHX860UD20-16H modules, Aeneon’s XTune AHX860UD20-16H-K-4G dual-channel kit is the only product in this roundup to achieve its full ratings at stock voltage. All of its competitors use higher-voltage “factory-overclocked” settings. But this key advantage comes with a disappointing lack of automatic configuration data, forcing neophytes to jump into unfamiliar territory of manual BIOS configuration, just as with competing products.
Memory that doesn’t require over-voltage to run at its rated speed probably uses higher grade chips, adding to the product’s expense. That added expense shows up as a slightly elevated Web price starting at around $360 for Aeneon’s AHX860UD20-16H-K-4G set.
