Mark memory page as invalid

[Kerlingen]

Does anybody know a way to mark a physical page of memory as invalid or bad somehow on Windows x64?

One of my RAM modules sometimes has a single-bit error at the same fixed address (found by memtest86+). The memory page is located in higher RAM, so it will be unused right after a reboot, but eventually Windows will use it for programs (unexpected crashes) or caching (corrupted files). I want to make sure Windows never tries to store anything on that memory page.

I can't get a single RAM replacement module, I would need to buy 6 new modules. I would like to prevent that if there was an easier fix.
