GM965 Memory Data Corruption on Dell Vostro 1500 Windows7 x64

GM965 Memory Data Corruption on Dell Vostro 1500 Windows7 x64

Some time ago, Intel detected a bug related to a wrong dynamic video ram assignment (DVMT) on its GM965 chipset. This affect several Dell Notebook using the GM965 chipset and VBIOS version 1466.

To solve the issue, Intel emitted a new VBIOS version1588, which can be found at least in this driver

The VBIOS must be combined with the system BIOS by the system or motherboard manufacturer before it can be flashed.

Based on that, Dell emitted the following BIOS updates:Dell Inspiron 1420 A09, Dell Inspiron 1520 A09, Dell Inspiron 1525 A09, Dell Inspiron 1720 A09, Dell Latitude D530 A07, Dell Latitude D630 A12, Dell Latitude D830 A13, Dell XPS M1330 A12, Dell Vostro 1400 A09, Dell OptiPlex 330 A15.

That left the Vostro 1500 behind.

See this thread for more details

The symptoms:

This bug causes memory corruption with a lots of blue screens (BSOD). Also, copying or compressing very large files (500mb to 1gb) can end on a corrupted file or unrecoverable ZIP file.

Looking for:
Any way to solve this issue. I need a driver, custom driver, modded driver, custom application, whatever that help me avoid from suffering any more BSOD with my vostro 1500 with GM965 chipset and VBIOS version 1466.I have tried many Vista x64 and Windows7 x64 drivers, and even they seem very stable, somehow still have the bug.Please, I have lost all faith in DELL.
