So i finally got my 8800gt last night and i spent a couple of hours putting my new system together. Thankfully everything worked first time(yay!).

So i ran cpu-z to see how my first c2d was running and below it gave the following readings:



Also my RAM seems to be at 5-5-5-18 according to cpu-z.

this is my first build with DDR ram and also a c2d processor. Im using the ga-p35-ds3r MOBO. I havnt changed any BIOS settings as of yet, just got windows on there and put in the gigabyte CD and the EVGA cd, thats it.

Any ideas?

Errr... It's Speed Step. When your system is at idle (doing nothing), it reduces the multiplier (usually x6). I'm guessing your default is 8. So 333x8=2664mhz or 2.66ghz. If you put your system under a load, it should jump back to stock speeds.

you can turn Speed Step off in the BIOS if you want.

I have a similar issue with my AM2 Black edition 5000+. When i first installed it i was able to set the multiplier real easy in my bios, and CPUZ recognized it and all was happy.
Last week I gotta little greedy and got a new HSF (was only using stock HSF and system was running @45-50 C)
I installed it last night, now everything is perfect except....
BIOS and Windows say that my Chip is running at a 15.5x, but CPUZ (and everest Home edition) report it at 13X.
I don't get it at all...
Specs:
MSI K9A running 1.7 AMI Bios (which is latest)
AM2 5000* Black Edition
3GB Dual Channel Ram all Crucial Ballistix
(1) Diamond HD2900XT512PCIE

The only thing i can think of is that when i went into the BIOS after i installed the new HSF and saw how much the temp dropped (i run at 28C-35C now), i went to play with the multiplier's again, I accdentally hit pgup and it set the mult to Auto, which changed the CPU ID to "5000 MHZ @B_u_ " or something funky like that... so i went back down and changed it to 15x
but the CPU ID stayed the same even though it reflected the right multiplier and Frequency.
Maybe I should take the CPU out and reseat.... or rather clear the BIOS first and see if that fixes it.
I just don't get why CPUZ and everst would report diffrent readings than Windows XP and the System BIOS...

AMD uses Cool-n-quiet. Which basically does the same thing. Although, setting it up is different then speed step, that I'm more familiar with. Not sure what to advice for the 5000+.
November 7, 2007 1:38:51 PM

Turn off Cool-n-quiet in the BIOS for the AMD 5000+

If your system is stable, just leave speedstep enabled. There are instances where turning it off helps overclocking, but if you're stable, keep it on.

It is common for high performance RAM to "default" to slower than advertised timings. If you look, that RAM is rated to run on as much as 2.2 volts. Well, DDR2 stock voltage is 1.8V. It is highly likely that your RAM would be unstable at 4-4-4-12 at 1.8V. As a precaution to make sure that a system can boot, the RAM's SPD (default timings) are set looser to ensure stability.

If you want the faster timings, you'll need to manually set the timings in the BIOS, and you'll probably need to set the voltage higher than stock. Try 2.0V and do some memory tests. If it's stable, you can try lowering the voltage, if unstable, raise it.

No, its the MSI Dual Core Center feature. It overclocks itself at any software needed when the temperature permits it to run faster. Thats the reason why it happened when you replace the HSF.

November 7, 2007 6:25:07 PM

btw, about the RAM, it appears you need to give the RAM 2.2v to run at 4-4-4-12 at 800MHz. make sure you've got the voltage set, and then set the timings manually. most memory defaults to a safe speed that is guaranteed to work on installation.

Ummm...errr...no, You dont remember correct and you cant read correct either apparently. I never asked what speedstep was, I just didnt know thats what caused the 6x.
I simply stated that cpu-z showed the incorrect multiplier for my cpu and someone said speed step caused that. I never said I didnt know what speedstep or cool-n-quiet did, I just wasnt sure if I had speedstep or cool-n-quiet. Please get your information right if your gonna call someone out.
Im wasnt flaming this guy either kids, I simply stated that the question he's asking is right there in his mobo manual if he just bothered to read it.


Hmmm... now if I read your previous quoter correctly... ummm... here is goes:

Now, if I read that correctly you said, "I dont know what speed step is." (And you don't know how to punctuate either, but that's beside the point)

From what you said, I think he got his information right. Either that, or you can't remember what you've said/wrote.

Well, actually if you REALLY want to nitpick, you never actually said that you didn't know what speedstep DID... you just said you didn't even know what speedstep WAS... But I guess being someone of YOUR intellect, you would've already known what speedstep DID before actually knowing what speedstep WAS...

And if you had bothered to read YOUR manual, then you wouldn't have made your original post asking almost the same question that d3f1 asked. So before you "offer" anyone advice, give it to yourself first (and I could mean that in OH so many ways)...

Me as well. I feel the same way about DragonSprayer as well. I mean, WTF?
November 7, 2007 7:58:35 PM

C'mon guys, what about the OP?
CPU-Z always does that on my rig, it shows the SpeedStepped speed even when it's disabled, ie. many other tools or even a quick right-click Windows System Properties will clearly show the full CPU speed.
I figured other people besides me would be getting this, but haven't heard much.
I asked a couple of times, here & there but nobody seemed to know what I was talking about...
Anyway d3f1 it seems we can call this a 'known issue' now, heheh... so thanks, I was beginning to worry :) 
Re: SpeedStep
I run it in the very hot months because, I kid you not, it's hot! Also the electrical grid is having convulsions and they are begging you to cut power, and it's a hot time for my rig in June/July.
Other than that you don't really need it, but your rig will run cooler/quieter if it throttles down automatically when idle, which only makes sense.
Note that you can quickly enable/disable SpeedStep from within Windows, go to Power Management and select 'Always On' to disable.
So how's the new rig d3f1?

CPU-Z is showing you the correct "real time" multiplier. My guess is that you think you have turned off EIST but have not actually turned it off. What mobo do you have?
November 7, 2007 11:22:28 PM

Good god she got wtfpwned in this thread...

Anywho, is the speed step thing specifically a Core 2 Quad utility or any Core 2 based processor?

All core 2, duo and quad.

Hey, my CPU-Z now always shows proper CPU speed, but the point is it wasn't easy! I'm on ABit AB9 Pro (a superb mobo).
I found it must all be disabled in BIOS - the C1E CPU-power thing and SpeedStep, both.
Otherwise, even with it enabled in BIOS, whether or not it is in effect ie. power settings @ Always On and SpeedStep not in effect: CPU-Z will display incorrectly.
I was clearly running @ 300 x 8 = 2.4GHz but CPU-Z would show 300 x 6 = 1.8GHz (which is the SpeedStepped setting).
The point is, it cannot be trusted blindly - kind of complicated really,

Sooo... CPU-Z still displays it at 1.8ghz even on a load? It should show in real time when it changes the multiplier. CoreTemp and other apps will indicate the orginial speed that its set at, on the other hand. (or in other words you don't see the switch to your default speed)

Yes, and as I said, I have been waiting for others to experience this too... like the OP.
Of course, he may actually be SpeedStepped! But it seems that is not necessarily the case.
Assuming the CPU-Z guys are getting some reports (I have not reported to them) the matter may be addressed in v/ 1.42

You are correct in that you didn't have your mobo settings correct as I suspected. Everyone thinks that when they disable EIST that they disable speed step, as you have seen first hand this is incorrect. You might find that if you disable C1E only, it still disables speed step. This is how the Gigabyte P35-DQ6 responds and I suspect it is the same for the Abit. You are also confused about the fact that there is a problem with CPU-Z, it works correctly. I do not believe that you stressed your CPU and that CPU-Z never showed the multiplier increase. Try running Prime95 and CPU-Z side by side and watch the multiplier go up. As I said earlier, you can't trust Windows or some of these other programs to accurately reflect the current "real time" multiplier because they just pull the chip information that was programmed in at manufacturing and display that. You are correct about using the BIOS to disable speed step though, I don't trust windows to do that kind of stuff.

You might want to turn it back on and run prime 95 and CPU-Z as well, you might find that it is working properly and want the lower temps. This is, of course, unless you plan to do some serious OCing, because at that point it may cause instability, as said earlier. As I said earlier ignore the difference in readings and rely on CPU-Z, it is telling the truth.
November 9, 2007 3:02:02 PM

Yes it's all very interesting Zorg.
So it seems that with C1E and EIST enabled in BIOS, it doesn't matter your Windows Power settings, ie. 'Always On' because SpeedStep will be active.
It's strange though, that many different reports show full CPU speed @ 'Always On' with reduced CPU speed @ 'Minimal Power Management' - when in fact CPU-Z shows reduced speed with the Always On setting.
Clearly with Prime95 running, the moment it starts CPU multiplier and voltage jump to maximum.
Regardless of Windows power settings...
I actually have 3 BIOS entries: 'Thermal Control' (enable/disable); C1E (auto/disable) and EIST (enable/disable).
With it all Enabled, I am getting full speed and voltage under load - which is all I care about! Didn't trust it...
But I believe! :D  So I may as well leave it all enabled (WTF, this poor 15A circuit is already heavily tortured).
Note: Running Prime95 for 1 hour got my O/C'd E6420 all the way up to 51C...!
It's funny because my first core runs ~60% and my second ~40%, with task manager reporting ~50% CPU usage. Is this typical?
Anyway, I s'pose it'll get hotter still with both cores @ 100%...

November 9, 2007 6:06:16 PM

I'm happy to see that you believe in the almighty power of CPU-Z. :bounce:  :lol:  (I'm sure I'm going to hell for that little joke.)

The Thermal Control has nothing to do with EIST as far as I can see from the Abit website. I would definitely leave it enabled.

Quote:
Thermal Control

This option enables or disables the thermal monitoring.

Maybe you are using an old version of Prime95. The older versions would only run single threaded and you needed an instance running per core. Try Prime95 25.5. This version will run an instance/thread for each core automatically. I don't know what you use to monitor temps but I like Core Temp.
