I can't disable EIST

[peter89]

I'm trying to use the turbo mode to oc this new 920 D0, but the multi keeps dropping to 20. I've disabled EIST and the other energy saving options in bios. and I went into the power management options of windows 7 and set it to high with min cpu set to 100%. As soon as I put any kind of load on the CPU the multi drops to 20. I've tried multiple bios and still no luck. I open turbo I7 and the Eist box is checked even though I disabled it in bios. Could this be a bad processor?

Re: I can't disable EIST

Do you also have C1E disabled. Just a wild guess.

Re: I can't disable EIST

ya, I tried everything including clearing CMOS. I think it's the CPU

How are your temps and cooling?

Dynamic frequency scaling (also known as CPU throttling) is a technique in computer architecture where a processor is run at a less-than-maximum frequency in order to conserve power. Dynamic frequency scaling is commonly used in laptops and other mobile devices, where energy comes from a battery and thus is limited. It is also used in quiet computing settings and to decrease energy and cooling costs for lightly loaded machines. Less heat output, in turn, allows the system cooling fans to be throttled down or turned off, further decreasing power consumption. It is also used for reducing heat in badly cooled systems when the temperature reaches a certain threshold. Most systems affected by this are inadequately cooled overclocked systems.

Give a try at this utility too...

Re: I can't disable EIST

Excuse my ignorance javanese but what is the file in the link you provided and how do I use it? My max core temp is 72 under load. I ended up exchanging the CPU at Microcenter and the new one does the same thing. The good thing about the new CPU is it seems to like the 20 multiplier alot more than the previous chip even though it's from the same batch.
The strang thing about this chip compared to every other 920 i've seen is that in bios the qpi/vtt voltage options go 1.280,1.30,1.320 ect. Every other 920 i've seen the qpi/vtt voltage options go 1.275,1.295,1.315,ect.. I don't know if this is normal or if my mobo is acting up. I don't know if I should reinstall w7 or not either.

what program are u using to see that the multi drops below 21?? in easytune it should stay on 21 even with c1e and other options enabled ect

Re: I can't disable EIST

turbo i7, I'll check out et6 and see what it says.

Re: I can't disable EIST

the utility in the link is i7 Turbo. Just lets you watch the multis ...
It might be the same one you call turbo i7 ... :/

Give us a full template of your overclocking bios settings.

Edit: And btw my qpi/vtt voltage has the same numerical progress as your new one. (1.28 - 1.30 - 1.32)

Re: I can't disable EIST

A few things I have to ask, are you using an ES CPU?

Are you using the latest easytune?

Are you changing any CPU/Memory settings in windows, if so with what program?

With C1E and EIST Disabled the Turbo 21 multi should not drop, unless you are using a ES CPU, or you are using an older Easytune, that is why I asked those things.

What BIOS are you using?

Peter says he got it from Microcenter and its the second one to do this, makes me think the motherboard. the QPI voltage increments are the same as mine, so no worries there.
By the way, is that D0 stepping chip you got the one on sale for $199?

Re: I can't disable EIST

the new version of cpu-z also shows the multi changing only easytune and older cpu-z shows at it stay at 21

Re: I can't disable EIST

Ahh, sorry I guess I missed that.

Well, hopefully it is just one of the other issues/causes I mention then.

Re: I can't disable EIST

I'm overclocking through the bios, I'm currently using firmware Fd4, I've also tried FA,FB and FC5. I'm pretty sure it's not an ES because I bought it at Microcenter. Would CPU-z identify it if it was? These are my BIOS settings.

As you can see here the EIST box in Turbo i7 is checked even though EIST is disabled in BIOS

Re: I can't disable EIST

Ya, it's not an ES. CPU-z would show that, and you wouldn't have got one at microcenter anyway.

You did not list C1E in your BIOS settings, do you also have this disabled?

Re: I can't disable EIST

I think 1.28581v is too much for a D0's vcore mate on a 180bclk.
Try using the "normal" option or start testing from a lower vcore, lets say 1.16v and above.

Put 1.65v on the rams also. They might be underclocked but they are running on a 180bclk.

Try disabling the "CPU thermal monitor" and the "Bi directional prochot".

You could also try leaving both QPI link speed and uncore clock ratio on "auto".

I m not familiar with the "ES CPUs" Lsd mentioned so no remarks on that.

Hope any of this helps.
