Windows 7 Ultimate 64-bit

Ok, I think I should report that I have solved my issue. To be honest, I feel kind of stupid about it. It basically came down to flashing the BIOS. I know, totally noob mistake right? But there it is: make sure you have the right BIOS for your processor/mobo combo. Live and learn.

Windows 7 64bit RTM

I'm not sure if it's relevant to this problem , but I have an ASUS board (M2N-E SLI) and it apparently gets unhappy if you try and use ram rated at the wrong voltage .. perhaps it's worth checking that out too?

Windows XP/Windows 7

Hello Everyone,

My system was also slows down when I boot Windows 7 64bit with 4GB RAM. I was using Windows XP 32bit with 4GB RAM from past 1 year with no issues. I played heavy games, installed heavy software on my system, and my system had no problems with 4GB RAM.

My system's specification are given below:

Processor: Intel Core2 Due 2.4GHz (6600 Model)
Motherboard: nVidia P6N Platinum Edition (nVidia 650i SLI Chipset)
RAM: Kingston 4 x 1GB, 800Mhz (All RAM have same speed and brand)

VGA: eVGA (nVidia) Geforce 8800 GTS 320MB version

I also tested Windows 7 RC (32-bit), and also found no issues with 4GB RAM. But Windows 7 (64-bit) had this issue with the above hardware.

I was able to solve my issue. I just updated the BIOS on my MSI nVidia P6N Platinum Edition (nVidia 650i SLI Chipset).

Now Issue is resolved. Now Windows 7 start with normal speed with 4GB RAM. So other users should update their BIOS, and try again!

Looking Forward,

Best Regards,
Azeem Bhatti
