RAM problem

  Graham. 13:37 03 Jan 2010

I have a dual-boot system with Vista and Windows 7 64-bit.

I have 4 GB RAM. When I check in Computer Properties, in Vista it shows 4 GB, but in 7, it shows 4 GB (3.25 GB usable).

Is there something I should do to correct this anomaly?

click here I looked into this in great detail. If you cant find "Memory Hole for PCI MMIO" I will need your motherboard make and model and i will find it for you.

I had this when using dual boot XP 32 bit /W7 64 bit. With 4 Gig RAM installed. Only cured it when XP went, as the boot ini somehow affected the whole PC. Is The Vista 32 or 64 bit?

First suggestion no good. The Motherboard is Foxconn G31MX/46GMX.

Did you go into your motherboard BIOS and see first?

In your BIOS, Go to advanced Chipset features and enable "Memory Hole at 15M-16M" Save changes and exit BIOS

Thanks, just doing that as you replied. Unfortunately, nothing has changed.

Uncheck the Box in msconfig as per my other thread and restart computer

According to this

It's a chipset limitation.
