Multiplier getting bumped down to 6 from 9?

[zoebisch01]

Hello, I have been running my E6600 @ 357x9 for a few months now on 1.18 V, good temps etc. I am not having any upfront issues but have experienced something odd recently and wanted to see if anyone has heard of this problem.

[edit]
Ok after a little more digging....I ran CPU-Z and low and behold my multiplier is getting bumped down to 6 from the 9 in the BIOS when I boot into Windows. Any suggestions on what to do aside from clearing CMOS and a possible reflash?
[/edit]

Does anyone have an idea what can cause this? I am at a loss.

Thanks!

Crucial Ballistix 6400 x2 GB 44412 1:1
E6600 @ 357x9 1.18 V ~35 °C idle ~45 °C load

Windows Vista 32 bit Business

PS, what other good cpu benchmark freeware is out there?


[edit] Ok, yet more digging....Is this related to the Windows Processor Power management and if so how do I get it to work at the correct oc multiplier when it should be? [/edit]

It's called "Intel Speed Step" it's a power saving feature, that can be turned on or off in bios.

Sometimes labeled C1E or EIST or both, or just speed step.

Ok, cool. I just came across this on another site. So I need to ask though, is this also controlled in the OS via the power management settings?

Mods, Please can we have a sticky for this ? There must 10 a week asking the same question.

I was thinking the same thing, this along with "are these temps ok?"

let's just have a CPU FAQ

by the way, most of the time, it's a good thing, saved power

Happy 1,000th post, FireWolf.

In honor of that milestone, I will not ask why my multiplier dropped when I couldn't see all 4AGB of my system RAM when the CPU temp went to 42C.

Ok, it makes sense now that I understand what the issue is. Sorry for hitting the same question that has been answered a lot, but without knowing what the problem was I wasn't sure what to look for XD. So then anyone want to school me on how to set the OS to allow my oc to stay at full speed? I realized I had been digging in the power settings last week some time but I don't recall touching anything with the processor management. *shrug*.

Which is fine with me, as long as I can understand what controls this parameter. And, I personally wouldn't consider it anything like a n00b question about temp. All of my builds prior to this have all been AMD, with the exception of a Cyrix. And the technology was released after my last build so it is news to me.

Close, but no cookie for you.

Those are two different things.......not the same thing relabeled.

EIST is Enhanced SpeedStep Technology

C1E is Extended Halt State......

They are different technologies, and an Intel cpu can support one or the other or both or neither.......

Both technologies are controlled in the BIOS of the motherboard as well as in the OS.....you can turn them on or off in the BIOS.....but C1E is more difficult to get to turn off as some have found out with various motherboards.....Intel has stated that some cpus in their C2D line will continue to execute C1E even with it turned off in the BIOS.

There's a long thread on XtremeSystems.org revolving around the Intel BX2 motherboard, and this issue has been long discussed, even to the point of long back-and-forth emails between members and Intel engineering staff. Fortunately, an enterprising member wrote a very light script called "NoC1E" to completly disable it functioning on boot.
