Houdini sends some extra information about the usage of Large Pages to your chess GUI, you should be able to find it in the UCI log files.
When the Large_Pages option is enabled, and your Windows account has the privilege to "Lock pages in memory", Houdini will send one of the following two texts:
- info string XXXX MB Large Page Hash used
- info string XXXX MB Large Page unavailable (OS Error #), using standard pages

It's important to note that very often the Large Page allocation will fail when you're requesting a large block of memory. Windows memory gets fragmented quite rapidly and Windows will very often not be able to allocate a sufficiently large block of unfragmented memory.
When the Large page allocation fails, Houdini will fall back to using normal memory.

You can quickly test this outside your chess GUI. Simply double-click the Houdini exe and enter the following texts in the console:
- setoption name Large_Pages value true
- setoption name Hash value 512

I don't expect any situation in which enabling the "Large_Pages" option would generate a performance loss.

Hello Robert,
I put in the following texts in the console and uci shows unavaible Large_Pages. It is only using standard. How do i work around this? I have 6 Gb ram and only assign 128 MB to hash inside polyglot. Pls help, thank you. Oh wait... it shows exactly like you mention above. So it's working right???
