KeyboardDataQueuSize editing

so..here's a quick back story. I had an alienware m15x. I liked it, except that it had a problem with the response of the keyboard. Sometimes it would drop significantly, making typing pretty much impossible. I sent it in for repairs, and it came back still broken, so I returned it. For a little over the past two months, I've had the Sager NP5793 described in my sig. The system is amazing...except that it kind of has the same problem. It does it to a much lesser extent, so rather than making the keyboard unusable, it's just something of an annoyance from time to time. Recently, I heard about this registry edit, to increase the size of the keyboard buffer. HKLM -> SYSTEM -> CurrentControlSet -> Services -> kbdclass -> Parameters -> KeyboardDataQueuSize.

The article where this was described recommended trying to double the value...so I took it from decimal (100) to (200). That seemed to improve the problem...but not get rid of it completely...so now I have it set at (300). Again, I don't think it's completely fixed, but it does seem to be better. Basically what I want to know is why the article would advise only doubling it. What am I risking causing harm to by increasing the value further? Is there any reason this value would ever not be set to its maximum? Thanks for the input.
 
I have the alienware m15x, and fixed it with a bios flash. Maybe sager has updated their bios.
Edit: We spent about the same on our notebooks, and your score is almost double my 3dmark :P

I don't think putting it at 300 or more will damage it, but if you do, it only takes a minute to backup the registry.
