Do you guys use speedstep?

I was wondering if its worth using just to keep the temps down while its not being used?

Is there a noticeable sluggishness going from down clocked to max speed?
 
Always have speedstep & turbo on. Don't notice any difference with it changing, not even when it first came out years ago.
 
I have it on for cool idle temps and to save power. Having a four PCs on usually at once isn't cheap to pay when electric bills are due...
 
Yes indeedie :cool:
No slugishness mate.
The time it takes a modern cpu to go from 0-100 is something like 100th of a nanosecond.

Only reason to disable those things is if your overclock is unstable with them. At 4.4 to 4.6 I wouldn't expect that, as voltages aren't quite as 'on the edge' between life and BSOD for that to be occurring normally.
 
You guys are all legends, dunno why I bothered with googling for forums when where I buy my stuff from has so epic people here :-)

tyvm.. brb reboot! :D
 
For my setup I can get by with just letting the turbos go up to 4.6GHz, leaving main clocks alone, vcore on auto, pll overvolt enabled, and loadline calibration notched up a setting from 'off' to 'llc level 1'.

Seems to vary from board to board how many levels, etc., there are with LLC, mine has 'off', 'small amount' / llc1, and 'moderate amount' / llc2 (and is a gigabyte one so different bios to yours, but still..).

That's it, along with a Noctua air cooler to keep the system in check. I don't mess with any specifically-named offset setting for voltage, or anything else in my config. From what little I know, the combination of auto vcore and LLC is keeping my voltages in check from being either too high or too low, and acting as a kind of 'dynamic offset'.
 
Well with the speedstep on, my idle temps are around 28-32 which is better than 40 24/7 and my room (if you read my other thread) isnt suffering so much ;)

I do have an overvolt option but I think I have it set to auto.
 
Ive tried using it and turbo boost on my I5 and noticed some horrid lag in games,its like the games are not strenuous enough to trigger the higher GHZ or boost :(


it seems to work if i use a stressing app like orthos though
 
I do use it about 90% of the times, though some encoding app's I use don't utilise it properly, occasionally speedstep will jump on/off constantly through an encode, meaning my processing power jumps from 4.4ghz to 1.6ghz every 15 seconds or so slowing things down. Its less hassle just to reboot turn it off, encode, reboot, turn it on.

I must stress this is a program specific problem (that is/has been fixed, not updated in a while) and is not aimed to discourage you from speedstep, its a wonderful feature :-)
 
You can control the speedstep feature in windows 7, in advanced power options you can change the minimum processor state to what you like, set it to 100% or slightly lower if you feel some games/apps are being effected by the changes in speed.
 
There aren't any negative side effects to leaving it on plus you do get to save power and lower temperatures somewhat. It enables and disables itself so fast you won't even notice any fall in performance.
 
I leave mine on on my 2500K, no difference in performance. Speedstep will increase clock speed performance when it needs too, otherwise it will just run at a lower speed.
