Testbed and Methods

Well, the specifications of Aeneon memory modules suggest that this is a pretty ordinary solutions, however, it is not X-bit labs’ strategy to take specifications for granted blindly :) You all know that very often some evidently budget solutions can acquire a new image after skillful overclocking experiments. And very often the results of these overclocking experiments can turn out quite unexpected. To be honest, we expected something like that from our today’s heroes – the Aeneon memory modules. Why? Well, they are directly related to Infineon, and the Infineon memory chips are often used in DDR2 SDRAM DIMMs designed to run at 900MHz frequency.

First, we decided to test the 512MB AET660UD00-370A98X memory modules. However, before we pass over to discussing the actual benchmark results, please take a look at our test platform configuration:

  • Intel Pentium 4 520J CPU (2.8GHz, 1 MB L2, Prescott D0);
  • ASUS P5WD2 Premium mainboard (LGA775, Intel 955X);
  • Aeneon AET660UD00-370A98X and AET760UD00-370A08X memory modules;
  • NVIDIA GeForce 7800 GT graphics card (PCI-E x16);
  • Maxtor MaXLine III 250GB HDD (SATA150);
  • Microsoft Windows XP Professional SP2.

The mainboard BIOS settings were as follows:

  • Performance Mode: Auto;
  • HyperPath3: Enabled.

We ran the tests at higher memory voltage set to 2.0V. We didn’t go any further than that because it is not safe to increase the Vdimm beyond 2.0V for the memory modules without heat-spreaders. So, we could only play around the 10% voltage increase. At the same time, I would like to point out that overclocker memory modules built with Infineon chips work just fine at this particular voltage, so we had every right to expect Aeneon modules to fully reveal their overclocking potential at the Vdimm set to 2.0V.

The memory stability tests were carried out in two consecutive steps. At first we resorted to the Memtest86+ utility version 1.65 to make sure there were no errors during operation. Then we reconfirmed this result by running S&M 1.7.6 and Prime95 24.13 utilities in Windows XP. This two-step approach ensures that we get trustworthy results.

Now that we have explained the testing procedures in detail, let’s get down to the actual benchmarking results.
