What's the maximum RAM on an Acer Aspire One 522 netbook with windows 7?

Hi! Acer Aspire One 522 is the hottest netbook of Taiwanese manufacturer, Acer and is a competitor to netbook D255 with an Atom N550. It is the Acer's first netbook with the new AMD Fusion C-50 dual core APU (Accelerated Processing Unit).

This model includes AMD C-50 APU - a high speed processor unit with clock rate 1 GHz. It also contains the graphic unit - AMD Radeon HD 6250.

It contains HDMI out and a multi-in-1 card reader, which can accommodate additional memory formats in addition to the regular SD and MMC.

The authenticated Acer supports:

1. DDR3 1066 MHz (up to 1 GB) system memory - for Windows 7 Starter
2. DDR3 1066 MHz (Up to 2 GB ) system memory - other OS
3. Dual-channel DDR3 SDRAM with a module support of one SODIMM

But, it was tested with 4 GB RAM and you can upgrade the DDR3 10600S RAM (1066 MHz) to a maximum of 4 GB by one single bank by shifting to the Windows 7 professional. Kingston (KVR1066D3S7/4G) - 4 GB bar was tested with this model and found perfectly suitable.

System requirements of Windows 7 professional:

· A 1 GHz or more faster 32-bit - x86 or 64 – bit – x64 processor

· A 1 GB RAM/2 GB RAM for OS 32-bit/64-bit respectively

· Required hard disk space - 16 GB/20 GB for 32-bit/64-bit

· A graphics device (DirectX 9) with WDDM 1.0 or higher driver

Hence, I recommend that you can go ahead by upgrading with 4GB Kingston (KVR1066D3S7/4G) RAM.
