3770k feels snappier with EIST ON?

post #1 of 4
Thread Starter 
I have experimented with having EIST on and off (so the CPU stays at the set frequency, 4.6 in this case), and for some reason, Windows actually seems snappier with EIST ON (so it clocks dynamically up and down) than off (so it stays at 4.6 all the time).

All other settings are the same, but I find this totally counterintuitive.

I supposed I could be mistaken, but I notice it each time... is it possible the CPU simply functions better with EIST on instead of off, and that is why Windows feels snappier with it on, even though it is clocking dynamically instead of staying at the fastest frequency?

Maybe it only seems snappier because it is clocking up from the lower speed. You could be used to idling at the lower speed, and then suddenly as soon as you use something processor intensive it is much faster. It seems impossible that everything could run faster with a feature that slows it down.

I agree. However, it seems to me that basic windows tasks feel snappier with EIST on ... the system just feels like it is responding faster ... I'm wondering if (aside from my possibly seeing incorrectly) the system and / or Windows just works better with EIST on or something. Like perhaps the CPU is designed to run with EIST on and even though it dynamically clocks the processor speed, it still somehow works better with dynamic clocking than static at the highest speed.

Maybe your overclock is not as stable as you think? Unstability can result in loss of performance rather than crashes, try bumping the voltage a little bit, disable EIST and see if it's improving.




Otherwise, I really dont know!
