Hi, I am using MK700/710 keyboard and mouse combo. I use them for gaming most time. i have issue about keyboard buffer limit. when I try to press more than 2 keys on my keyboard, the 3rd key would not response. I have installed driver for it, but still the same. Is anything i can do to increase this cap?

Otherwise this would be the same answer as in another post, but you added a nice twist so:
What you are talking about isn't buffer size, but keyboard's ability to process multiple simultaneous keys pressed down. This depends on the matrix used in the keyboard and ranges from 1 to about 6, 7. Most commonly, 2 keys work but more can lead to problems.
Buffer size on the other hand determines how many separate keystrokes a keyboard can remember in case it lost connection to the PC. Usually these buffers are large enough so that you don't notice any keypress loss. I'm sure your keyboard works just fine in this respect.
This is cc of the answer in another thread (Media K200 keyboard...):
Seems like your keyboard uses one of those super cheap matrices Logitech seems to be using en masse lately.
Unless I'm mistaken, there's nothing you can do but buy a keyboard with a better matrix. If you ask Logitech, the only keyboards that are certified to work with 3+ key combos are the G-series (gaming). Otherwise it's hit'n'miss - some models work fine for frequent key combos, some don't.
