Win7 GMA950 low memory issue

I have VGN-TXN27 i945 2Gb RAM Win7 system. I upgraded it with 64Gb SSD so I turned off system swap (but it looks like the issue is the same even with the swap but it may takes a bit longer time to reproduce it with large virtual memory).

I have problem with the graphics. When the memory usage is about 80% (or higher), the screen may become black and it looks like the system hangs and not responding to any attempts to come back to the operation mode. I could only hold the power button to force the turning off so all changes in the files (documents, photo etc) are lost.

The issue looks common for GMA 950 systems because I see exactly the same problem on VGN-TZ250 Win7 PC (the same i945 with 2GB RAM).

I'm not sure but I think the problem is in sharing the system memory between the Win7 and GMA. Are there any way to "reserve" the fixed amount of RAM for GMA if that is the case. Otherwise are there any other solutions?

 

What about if you turn on swap and make it 300MB or so?

Also, are you already using this driver?

Driver is the same. Set swap to 400Mb.

Result is the same - black screen. Power off/on - gadgets alligned to 1024x768 (1366x768 originally).
