Overclock question

[Henleyz]

Should I leave Intel SpeedStep and the C-States enabled or disabled? They are currently enabled and have no problems at 4.4ghz at 1.168v on a 4770k...

Enabled. SpeedStep is throttling which protects your processor if the temp were to get too high.

Okay thanks!

Okay thanks!

It doesn't seem to let me using Tapatalk?

Ah well...you don't have to.

once you know your overclock is stable feel free to go on adaptative voltage and use the powersaving features that way your cpu will throttle down and undervolt when not under load (browsing web, office work etc,)

what are the best ones to turn on?

Haswell Low Power Modes:

 

 

•Cpu ratio mode- Dynamic

•Enhanced Turbo- Enabled

•CPU core voltage mode- Adaptive

•CPU ring voltage mode- Adaptive

•Intel C-state – Enabled

•C1E Support- Enabled

•Package C-state limit - Auto

 

SOURCE prokon's haswell oc guide:

sometimes the cpu wont throttle down right away but after a couple minutes doing stuf in windows it will..

So when I'm using the system it will stay at 4.4ghz is it? Then when I'm idle it could drop to 3.0ghz or am I wrong? Just trying to understand how these power saving modes work

even better, when the cpu goes into some kind of load it will pop to 4.4ghz instantly (no performance hit cant stress this enough) and when idling or browsing light stuff it will fluctuate to as low as 1ghz at times with vcore going as low as 0.6v...but the volts and frequencies bounce a lot its normal for haswell, listen to prokon it explains this very well, in fact the whole guide is awesome you should follow it and validate your overclock...intel extreme tunning utility is a must have as well...

Nice I'll give that a shot, I just hope it doesn't effect performance or anything like while playing games either

nope it wont dont worry...just change the ones ive mentionned and you will be fine!

i did it myself and it works flawlessly!

[i_build_nanosuits]

Look at that, i was wrong it can go as low as 800MHZ and it also disable cores...so i'm currently running as you can see a single core at 800mhz (0.8GHZ) @ 0.72v!

That is nice, but just one question, would your system not be slower now because your at 800mhz instead of been at like 4ghz? I doubt as soon as you open up like a browser it will shoot back up to 4ghz, and even at that would it not be very like glitchy and jumpy? I'll still try it all the same i think...

[vm'N]

Certain task doesn't require the power of a haswell processor clocked @ 4GHz.

Scenarios like webbrowsing is totally possible on a 1GHz haswell processor (to an extent).

It is about not wasting cycles (4GHz is 4.000.000.000 hertz (cycles)).

it does jump up as soon as you hit somthing, if you launch a web browser for example it instantly bump to 4.3ghz in my case, no delay, not loose of performance no nothing...try it you'll see for yourself!

No actually. SpeedStep turns the CPU clock down when it isn't in use.

 

Throttling is a different thing entirely. C1E is part of thermal control but Intel has a separate thing for it in the BIOS(which you can disable... but don't).

Okay sweet, so all in all it saves electricity and expands the life of the CPU with no performance increase or decrease?

SpeedStep throttles as well.

That's changing p-state to reduce thermals and power consumption not needed- not to protect the CPU from overheating.

http://en.wikipedia.org/wiki/Dynamic_frequency_scaling

 

"Dynamic frequency scaling (also known as CPU throttling) is a technique in computer architecture whereby the frequency of a microprocessor can be automatically adjusted "on the fly," either to conserve power or to reduce the amount of heat generated by the chip."

 

Implementations

 

"Intel's CPU throttling technology, SpeedStep, is used in its mobile CPU line."

 

I think we're done here.

Hmm, maybe I am mistaken.

 

But I do believe there is still thermal throttling in place without speedstep. (Advanced thermal monitoring in my BIOS).

exactly.
