Windows 7 версиий выше чем Home ограничена использованием 2-х процессорных гнезд, вне зависимости от общего числа ядер.
It's a bit difficult to find the information from an official source, but I have read that Win7 Home Premium is limited to a single CPU socket. Pro and Ultimate are limited to 2.

You have to read the End User's License Agreement (EULA) for each product to get the correct answer. If you read the EULA for Win 7 Ultimate the answer is two (2) processors noted under:
2. INSTALLATION AND USE RIGHTS.
b. Licensed Computer.
You may use the software on up to two processors on the licensed computer at one time. Unless otherwise provided in these license terms, you may not use the software on any other computer.
You can download the individual EULA from
