I can confirm this error, not only will the Intel HD Video driver on my MSI PC Mate disk not install at 1024 but their website's Z97 - Intel VGA Driver. - 2014-05-23 - 10.18.10.3540 - Win8.1 32, Win8.1 64, Win8 64, Win8 32, Win7 32, Win7 64 - intel_vga_8_mb.zip will not install or boot on win 8.1 Pro x64 at 1024. Every time I get the (Winkey) WBSOD. But it runs fine at 512 or below, and this quite obviously is not acceptable as HD4600 is a significant improvement over my other system's 4000, so I have no plans to buy another GPU. Fix us please Intel. More are on the way...

In most cases, your computer manufacturer has already configured your computer to use the maximum amount of graphics memory that is possible for your particular model. I recommend checking with the motherboard manufacturer for the actual maximum graphics memory supported by your BIOS and whether it is possible to increase that amount.
