I could have seen this being usefull a couple of years ago, especially before vista came out, but nowadays I think that if you need more than 4gb of ram, 64 bit windows is the way to go. Otherwise perhaps we could also try to use the Intel HD driver from WinServer2008 or WinServer2012 on Win7 - don't know if anyone has tried this? CraigmontHunter wrote:I would imagine that this patch just enables true PAE, and 36-bit adress length, which is what windows server 2003 uses to access more than 4gb ram. This has been reported and discussed on Intel forums: It is up to Intel to make a change perhaps in a future release of the driver to correctly detect PAE. It is a shame that the Intel HD driver for Win7 doesn't properly check for PAE to correctly decide its MMIO address region. #Windows 7 sp1 4gb ram patch driversAndy says: at 4:32 am I can’t believe it, but I got Win7 to work on a Intel HD 3000 graphics (i3 Sandy Bridge) with this PAE patch.Īlmost all video card drivers seem to be fine and do this PAE detection properly except the Intel HD 2000-4000 driver for Win7 (but the Intel HD driver for WinXP does do this PAE detection correctly). #Windows 7 sp1 4gb ram patch how toThe WinXP driver for Intel HD graphics (2000 to 4000) can be downloaded from: Read the comments at the bottom of the following link, they share many people's experiences with this and instructions are provided in the first quoted post below on how to edit the INF of the Intel HD WinXP driver to trick it into saying it is compatible with Win7. As a fix many people have reported that if they use the WinXP Intel HD driver on Windows7 PAE-patched-kernel then it works (with the downside of not being able to use Aero). This problem affects Intel HD models 2000 to 4000. Manual kernel patch instructions: Automatic Tool: But the problem with the Thinkpads is that the Win7 driver for Intel HD integrated graphics does not have support for a PAE-patched-kernel but the WinXP driver for Intel HD integrated graphics does have support for a PAE-patched kernel. The Win7 PAE kernel patch can be applied via manual instructions or via automatic tool. ![]() Here is the results of my preliminary research. While your comment is correct, there are no motherboards built into which more than 4GB of ram can be installed that don’t support either 64bit or PAE. One such utility can be found at /4gbpatch.php persons using this patch however should be aware that not all programs my behave correctly after applying it, which is one of the reasons the patcher makes a backup of the original.exe file before patching it so that it’s easy to revert to using the unpatched executable just by deleting the patched one and renaming the backup one. On another note there are also a few utilities available that can be used to patch 32 bit programs so that they may be able to take advantage of memory above roughly 2Gb making them hence LMA (Large Memory Aware), I myself have used one such program to patch the program Bryce 7.1 Pro from DAZ so that it can utilize additional memory (after all why have that additional memory accessible only by the OS when some Programs may also benefit from its use too). Additonally there are boot.ini modifications for XP that can be used to enable support for processors using HyperThreading or similar technology which can also help to improve performance for those using XP on a newer motherboard based system. ![]()
