Unbuffered Memory Module
Data Sheet

This data sheet describes the features and specification of the AENEON™ XTUNE™ 512MB DDR2 1066 MHz
overclocking memory module family.
XTUNE™ series is the AENEON™ solution for Enthusiastic Gamers striving for highest system performance while
experiencing a fast, stable and reliable system operation.
AENEON™, with the XTUNE™ series, is the first company that supplies High Performance Memory Modules
without overstressing the DRAM components with higher supply voltage. This will be paid back in higher lifetime
and reliability.
AENEON™ XTUNE™ series supports the EPP (Enhanced Performance Profile) standard. EPP provides a
Plug&Play solution and eases the use of overclocking modules significantly since the overclocking features can
be read out by all motherboards1) also supporting EPP. As a result the system parameters are automatically
adjusted to the overclocking parameters supported by the memory module. The most popular motherboards in the
market supporting EPP are NVIDIA SLI 680i platforms.

The 512MB single module can be organized as

64M x 64-bit DDR2-1066 based on 8 components 64M x 8-bit DDR2 FBGA components.

The single module is tested to run at 1066 MHz at a latency timing of 5-5-5-15 at the standard DDR2 voltage value
of 1.8 V.
The Dual Channel Kit is coming with two identical modules tested together in DUAL CHANNEL MODE at
1066MHz at a latency timing of 5-5-5-15 on several platforms based on the NVIDIA 680i and Intel 965 chip set.

Package Variants
The AXT660UD00-19D comes in the following configurations:
Product Type




2x512MB (1GB) Dual Channel Kit, n = regional versions



512MB Memory Modules
Overclocking Speed Grade DDR2-1066MHz CL5 at 1.8 V
240-Pin Dual Inline Memory Module (DIMM) with Gold Contact
Highest Quality Heat Spreader for preventing critical operating temperatures
Supports Industry Standard 800 MHz 5-5-5-15 (for non Overclocking operation)

Motherboard and BIOS have to support the EPP feature.In some Motherboard Model, EPP feature, has to be enabled in the BIOS settings.
Refer to the Motherboard documentation for further details. All the other overclocking capable motherboards have to be manually
configured using the parameters shown in the table.
