How to: Disabling SpeedStep with Conroe ES Steppings 4 and 5

[Rovtar]

what about yonah?

[stummerwinter]

At Yonah you don´t need it with BIOS 1.03c and 1.04, just disable speedstep in BIOS...

I wonder if this is needed for retail...Could this be made into a sticky?

[freecableguy]

I am working on a driver that will allow disabling/enabling EIST, C1E and the setting multiplier on boot or any time via the device manager. Should see it very soon. I just need to finish with my move right now, no time to do anything else.

With the P5B Deluxe when i disable speedstep and C1 in bios it works, no more speedstep.

thanks for the heads up

Just a quick post to say this works with a step 4 E6700 ES, where the first 32-bits are read as 0x62972089. I change to 0x61972089 and it works.

That driver would rock, FCG!

err why do we need to disable this thing? isnt it a useful thing where we can save some heat and electricity as well? or it does effect our overclocking? sorry for asking such a silly question (if it is..)

Thanks to Franck@X86 for his help, he had help me to find how to manage the multiplier :



approximately translated :

-use an MSR Editor same as CrystalCPUID
-Edit the MSR : 0x000001a0
-Set the bit 16 to 1 -> 0x61850089

into the power management of windows set always on

then have fun !!!

can you go to 10x multi and above

we really need that bad with these crappy intel mobos..........well mobos are actually ok it's the damn multi that's just too damn low and they OC too good

[Raja@ASUS]

wishful thinking, I tried it and the highest it will go is the max multi of your cpu, even if you select higher...

anyone know how to do this on a step 6 rev b2?

How is the progress FCG?

Is there already a known way to automate the disabling of EIST
so i doesn't have to be done manually every boot?
I thought i read about a way but do not find it any more at the moment.

Thanks.

OOps, too fast on the trigger, lost it upon reboot.

I was wanting to know if any one knows how to help me turn off speed step on a Pentium mobile four as it keeps throttling down and never comes back up when I use the CPU at 100% it just sitting at 1.2 GHz which is just crap. I have tired all the normal ways and a few programs however I think if I don’t hack the registry then its not going to work.

I downloaded crystal CPU however I don’t know the values to put into the program so if any one can tell where to either read up and figure it out on my own or just tell what I can do to help fix this crappie laptop feel free to make a post or tell me.

GREAT JOB!

Got ist also running for my MEROM...

MRS: 0x000001a0

from

EAX: 0x62970089

to

EAX: 0x60970089

Hi, I know that post was from about two years ago, but I was hoping you still remember about it. I'm quite interested in pinmodding my merom from 133 to 200. It'd bring my speed to 2.6ghz from 1.73. But as with all meroms/yonahs on intel chipsets, I would imagine that the multiplier will get stuck on 6x. I was wondering if you had ever attempted any bsel manipulation before on your merom, and could attest to whether this would successfully unlock the multiplier from 6x again.

Thanks
