polling rate on keyboard

[[UK] HeadShotKing]

I have a switch at back of my new mechanical corsair k65 keyboard and it has the numbers 1-2-4-8 and bios ,I found out it's to adjust the polling rate but I don't know which number is fastest 1-8,anyone know?

is only a gimmick due no one can press a key many times in 1 millisecond is useless, im have the same keyboard(k70) and is better save proceses on your processor and keep in 8 i I bet a game you do not notice any difference

I notice the difference because I have very fast reflexes so I keep mine on 1 now.

I wish I ordered the USA version now the uk ones have a tiny shift key

Polling rate is normally only adjustable for gaming mice... however it's what can make a huge difference. I wouldn't call this a gimmick for mouse, but not sure about keyboards.

1000Hz is great for gaming purposes.

For simply sake: Lets say you have a 120Hz monitor running at 120 fps. Updating the mice location 1000 times (1000Hz) means it gets updated 8 times per frame. 1 out of 8 is used, and 7 times are just waste. However, it gets pretty accurate that way since the mouse location is always fresh. As long as your computer does not slow down, and if 1,000 is the default, there is not much reason to lower the rate. It's basically just telling it how many times to check, so long it's not crazy low vs what you can see on screen and react to or the other way around and too high for older slower systems to handle, then it's not a problem.

This is how it would work for a gaming mouse, keyboard would probably be the same type of idea...

If 1 stands for 1000Hz, then that should be more than enough.

Although this can make some huge difference in mice (and should always be maxed out unless an issue), it is largely irrelevant for keyboards unless you can type faster than a few milliseconds? 1000Hz is most likely the highest to go, as more is just wasted anyways (unless you have 1000Hz+ monitors and micro-millisecond reaction time).

Logically guessing, it would be for your keyboard:
Divide 1000/#

Therefore...
8 = 125Hz
4 = 250Hz
2 = 500Hz
1 = 1000Hz

Setting it as '1' would be your best option, if 1000Hz. It's highly unlikely and not even required to go higher than this. You would only care about reducing it if the system can't keep up with it (which should be fine for a high-end system anyways).

There's a switch behind the K65, where the function is as below:
- 1, set the USB polling rate to 1 millisecond
- 2, set the USB polling rate to 2 millisecond
- 3, set the USB polling rate to 4 millisecond
- 4, set the USB polling rate to 8 millisecond
- BIOS, allow you to turn of certain advanced features in trade of compatibility with certain Motherboards

Switching to different mode will disable the keyboard for few seconds before it can be used again, while your operating system detects its driver.

Nice find - but to confirm (it's not 1/2/3/4 on that list, it's 1/2/4/8). The polling rate calculations, however match.

8 = 125Hz (that would be a polling rate of 8 millisecond - marked as 4 on that list)
4 = 250Hz (that would be a polling rate of 4 millisecond - marked as 3 on that list)
2 = 500Hz (that would be a polling rate of 2 millisecond)

You would want it on '1' (1000Hz - 1 millisecond), unless compatibility issues.
