Intel Speedstep Technology

[xu^]

Should i enable it or not ?

atm i have it disabled but was wondering is there actually anything to be gained by having it disabled ?

quite like the idea of having it enabled so when not doing much on the pc itll run slower and be cooler thereby extending its life?

thoughts please

You can try it, I believe it works in conjunction with C1E on some chips to not only lower clock speeds, but also CPU voltage, there could possibly be some instability issues if your chip cannot handle the lower clocks at the lower voltages or if the voltages are lowered before the clocks are and such. I personally leave that stuff off, but if I wanted to have a cooler idle temp and left my PC running with no load (I usually leave it folding at night), I would try out those enhancements.

Does that chip also feature the TM feature? That is also another deal I've read about, that my 6300 has that is similar to SpeedStep, or maybe it's replacement...dunno, Intel has too many options to save power that all seem to do the same thing lol.

I would say try it out, see if you maintain stability with your OC, it can't hurt to try, and will definately not hurt by saving on power.

I do use SpeedStep on my G/F's OC'd P4 Prescott build, it's a 3.0 oc'd to 3.5 and it works like a charm. Granted it will only drop the chip to 3.2 and I'm using the lowest voltage allowable by the board for that particular chip (1.38v iirc). So no voltage lowering, but it does help with idle temps for browsing and basic stuff.

Hope that helps!

I really don't see a point in it... Yeah, it helps keep your CPU's life up by a few months or so, but I don't really see a use in it... If you ocing it, then you've all ready killed the life of it.. I do see the point in power saving... If your on a budget and want that oc, then I'd say go with it..
I just don't see he point if you've all ready oc'ed it...

i odnt use it because if im running more than 1.35v thru mt cpu it will crash my system when it enters the speedstep/c1e state.

makes sense tho if you dont oc or its a htpc or the like which is on alot doing very little.

hourses for courses.

Laptop=yes, Desktop=no

I was just now searching how to disable it on this abit board I'm playing with. Anyone know how to disable speedstep on an Abit AA8 Duramax? It's either not in the bios or I'm blind.

enable it for all systems you have and you will suddenly have $50++ less on your yearly power bill. your system will not go slower, the switch is done in a few milliseconds - you wont notice it. also less power used = cooler cpu = less heat = slower fan = quiet. i dont believe in higher voltage = lifespan reduction that you can actually experience, but if you want to, add longer lifespan to the list.

if you have a highly overclocked system though it may become unstable because the voltage reduction isnt enough to sustain the clock frequency of the chip. just see if that happens and disable eist then.

Enable it, and if it's still stable, horray, you're saving power and your chip will live a little longer.

And overclocking does not kill, nor does a modest bump in voltage. Voltage levels like 1.5 and up can be slightly harmful. temps is the main killer.

If you overclock,no.If its stock,yes.Cant do no harm.

Has anyone here, other then amd users, actually had a cpu fail on them that they could trace back to a thermal issue other then a failed fan or poor heatsink mounting? Maybe I'm just lucky. I've been abusing cpus since the 286 days. =)

What is the 'trip point' for speedstep? >10%? >50%?

What's also interesting in my bios on this AA8 is that C1E has to be disabled to disable speedstep. Disabling EIST (enhansed intel speed step) didn't do a thing. Go figure.
