Does mouse lag indicate instability?

[opio]

I just oc'd my haswell core i7 and when I move the mouse it occasionally lags, does this indicate instability?

Well the reasons for mouse lag could be

1)bad mouse
2)dirty mouse-pad
3)a virus
4)if its due to overclock (the CPU will shut itself down to prevent damage).but it can be reason for mouse lag

try again with a different mouse

Is the mouse lag accompanied by a crackling sound in your PC? Is there black smoke billowing out of the case? Joking aside, I would say you pushed the machine a little past its limit. Sounds more like an overvolting issue though. Have you cranked up the voltage too? Unless of course you actually do have a bad mouse.

What type of mouse do you have; wired, wireless, optical, laser?

k first of all it is not my mouse, to answer bicycle guy's question it is a wired laser mouse.

I have been turning up the clock but leaving the voltage on adaptive

My ram is running at 2400mhz with the correct voltage that it's rated (1.65v)
Right now my CPU is running at 4.0ghz and stable with adaptive voltage, should I be changing the voltage manually like I had to on my RAM?

I just went ahead and reformatted my computer. Mouse lagging stopped, but still, I'd really appreciate if somebody could give me some info on voltages when it comes to CPU's

you can change the voltage manually

ensure :

1-the cooling is effective(proper airflow,if liquid dont worry)
2-do it step by step

increase the voltage to next level one by one and after each step stress test you cpu to ensure that it does not crash

your CPU will protect itself if it overheats but best avoided

here is a good guide if you have the patience to read it http://

Before you start to adjust CPU voltage you should download Prime95 and HWMonitor. As a starting point, launch HWmonitor with the overclock in place and check what the current voltage is (I'd estimate somewhere around 1.2V).

Now that you know approximately how much voltage is being used, access the BIOS and find VCORE, which will be set to auto. To adjust the voltage, you simply enter a value. Start with something slightly lower than the voltage you saw in HWMonitor and restart the computer.

Run a Prime95 Small FFTs Torture Test, which will force all the CPU cores to 100% load. This test will ensure that the CPU is being supplied with adequate power in a worst case scenario situation. Keep the test going for half an hour and if none of the Prime95 threads fail or the computer doesn't crash, go back into the BIOS and lower the voltage again. Keep repeating this process until you encounter instability.

Once you've established what the lowest voltage is, run another Prime95 test for a few hours. If any of the threads fail or if the computer crashes, you need to increase the voltage. It's all about trial and error.

Essentially, you want to achieve the lowest possible voltage so the processor outputs the least amount of heat.

I presume you already have an aftermarket CPU cooler? Don't overclock without one!
