Closer Look

For our test session Infineon was very kind to provide us the fastest solutions from their current product range: DDR2-533 (PC2-4200) SDRAM with the capacity of 512MB and 1024MB. While most companies have already tackled the production of at least DDR2-667 SDRAM, Aeneon family cannot boast high-speed solutions like that yet. Moreover, the latencies of the memory modules we had at our disposal are quite common: the nominal CAS Latency value at 533MHz frequency equals 4. However, we didn’t expect to see the world’s fastest running memory modules when we got our hands on the Aeneon memory. What we were promised was the unprecedented combination of high speed and attractive pricing, so we would expect the price to be Aeneon’s major attraction.

Anyway, right now let’s take a closer look at the specifications of the DDR2 SDRAM Aeneon memory modules from Infineon. First we will take a 512MB module marked as AET660UD00-370A98X:

  • Frequency: 533MHz DDR;
  • Nominal timing settings: 4-4-4-11;
  • Organization: 64M x 8 DDR2;
  • 240-pin unbuffered DDR2 SDRAM module with 512MB storage capacity, without ECC support.

The second module type we will look at is a 1024MB module marked as AET760UD00-370A08X:

  • Frequency: 533MHz DDR;
  • Nominal timing settings: 4-4-4-11;
  • Organization: 128M x 8 DDR2;
  • 240-pin unbuffered DDR2 SDRAM module with 1024MB storage capacity, without ECC support.

The memory modules specifications do not mention anything about the supported voltage, because it equals the standard value of 1.8V.

As we see, at first glance Aeneon memory modules look just like many other memory solutions. So, hopefully the famous German quality will reveal itself during the practical tests.

Here I would like to specifically stress the accuracy and thoroughness of the SPD report. The manufacturer documented not only the time when the given memory modules were made, but also the serial number of each product.
