speedstep and other bios options and overclocking myth or fact?

post #1 of 14
Thread Starter 
I have heard many times that you need to disable speedstep, virtualization, and anything else in the bios to get any decent overclock. I haven't disabled many of those things and still leave speedstep, virtualization, spread spectrum and whatever else I can enabled and haven't noticed any change in max overclock speed.

so is there any truth to this or no? it almost sounds like an assumption that it would make things worse without any real testing and then that turns into gospel of truth.

and if some of these things are designed to cut down power usage while the computer is idle why not do it? you create less heat for your computer room, you pay less in electricity bills, and make the cpu run less overall heat. why shouldn't we do this?

Speedstep can cause instablity.
ie your chip is stable at said multiplier, but not at a lower multi with the same fsb.
As for virtualization, I am not sure about that one.

One thing my bud pook found was in a newer version of our boards' bios, was an option in CPU settings for "Disable SYNC Mode".
He got a little boost from that as well.
If you don't need it, don't use it. That's the basic rule of thumb I guess.

I can understand the rule but some things people disable while they might not be needed sure are nice at times.

only time I can really see speedstep causing problems is on boards with the fsb straps on them. running at 400mhz on a p5b at x9 then dropping down to x6 chances are would push the mobo over the edge. I didn't think of that one. but you should be able to move the fsb around enough to get around that one. hell just needs one more mhz and your past that strap. I have yet to see that one though as I usually run around the 370-380fsb range or the 405 and 455 range any higher of a fsb I get unstable no matter what I'm doing

EDIT: how many people have seen instability that they have traced down the speedstep? if so what was the senario?


also just curious what is vanderpool tech and EIST?

If you're still stable with all of those enabled. My opinion, leave it on. Save energy!!! Save money!! Prolong CPU/Ram/MB life!!!
post #5 of 14
Yeah, if you use it, or want to use it, go for it.
If you don't need it, disable it

I hate speedstep I want 100% power full time. It's not like my 600w power supply is spiking my electrical bill, that's my two A/C units' jobs! hah.

dpawl there are programs out there that are supposed to be able to adjust how your speedstep works. if your cpu goes above a specific threshold it ups the multiplier to your liking. that way your only supposed to use what you need rather then use everything all the time just to open wordpad .

though wish I could find out what is going on with mine anyway. the voltage drops according to cpuid. speedfan and asus probe say the cpu gets the same voltage my temps don't drop and so yeah I donno.

But, but...
I want wordpad opening as fast as possible.
Really, I MUST type my readme files...


Seriously though, I don't want any delays
Call me wasteful, but I like it running on high
Plus I fold, so it'd run on max anyway.

eh can't say much about cpu usage myself. I fold as well ... wait you fold and your not helping out overclock.net? YOU TRAITOR!!!.. or are you just too lazy to add your name?

when I was just testing it out though with speedstep it didn't seem to give any delays. the speed adjustment seemed fairly quick and adaptive to the load. either way though maybe this can inform and help others out there who don't fold.

Can you verify that it actually changes the strap, in 'idle mode'...I am running 400FSB, 9x multi w/ speedstep enabled...no issues here bud.

I FOLD for OCN lol.
Just finally got it working correctly last week, 2WU's down and I am on the list.
Waiting for my postbit to show up =D
Also waiting on my 2nd flame

I want to fill my whole panel lol. I need an OC'd account now =D
