CPU-Z innacurate??

I have a dual core Pentium D 830 running at 3Ghz per core. When I run CPU-Z it always says my CPUs are running at 2808Mhz (2.8Ghz). When I change the view to the 2nd processor the clock speed is identical exact to the last megabyte of the speed of the other CPU, do both cores really run at the exact same speed all the time? And whats with this CPU-Z telling me 2.8Ghz, anyone have any comments or suggestions, thanx.

Any other CPU app says they both run at 3Ghz, but I think CPU-Z is the only one that measures in real time, anyone know of any other apps other than CPU-Z that run in real time?

Maybe it's a Pentium D 820 Dual Core (2.8Ghz). Mine has pretty accurate readings. Yeah, the only way to make sure is to check your main bios.

It defenitely is a D830, even CPU-Z says that. Can I access my bios without booting up?

No, whats so hard about booting up and hitting the DEL, F2, or whatever your bios key is?

Also, both cores will always run the same speed since they run off the same clock.

do intel procs come with a cool n quiet equivalent?


Yha its called Speed Step

I'd check to see wheter its enabled, becuase if so I do believe that 2.8GHz is the lowes it can clock your cpu down to
April 5, 2006 4:39:40 PM

Yeah, its funny everything seems fine, anywhere I check hardware settings whether it be in windows or other apps like system mechanic, they say everythings fine, they are running at 3Ghz. I checked the BIOS settings and everything. in there seems fine aswell.

Someone mentioned here that Intel's speedstep might slow it down to a minimum of 2.8Ghz, but everytime I check CPU-Z whether I'm encoding video (and task manager says I'm running at 50% 60% 70% even tried 100%) or just sitting idle it always says both core are running at 2808Mhz or 2807Mhz.

Well, I found this on the CPU-Z site FAQ:

Quote:
Q: CPU-Z reports my Pentium 4 3GHz or above with a 2800MHz CPU speed.
A: This is the effect of C1E (Enhanced Halt State) and/or EIST (Enhanced Intel SpeedStep Technology). Load your system and you will see the frequency increase to its nominal value.


So I don't know what to think, and I guess thats on a single core... :lol: 

Edit: try a real CPU load... Prime95 on both cores.
April 5, 2006 5:46:27 PM

that and check your temperatures

if you're CPU is running too hot to begin with than it would clock down to 2.8

Hey mpjesse, I'm beginning to get what you were saying!


LOL. At least this guy has a decent question. I'm tired of seeing these type of questions:

"Should I wait for Conroe or get AM2?"

"Should I get a Pentium 965 or a FX-60?"

"What's the best CPU for photoshop, the internet, word, and World of Warcraft?"

STFU! Read the god damned CPU charts!
April 5, 2006 5:56:11 PM

mpjesse.

I've learned to get used to it. hence why i lurk more than post

I've given up posting in the "which one should I..." threads.

it's the same fucking question over and over and over again
April 5, 2006 6:50:13 PM

Hey... where should I go for the best burger.

I was thinking burgerking.. then though mcdonalds.

Or maybe I should think different and go for taco bell.

Which would be faster?

:oops:  Oh... nm.
April 5, 2006 7:30:42 PM

McDonalds usually pwns in pure speed. Taco Bell is also usually fast as well.

From my observations, these chains are the slowest:

Sonic
Carls Jr.
Burger King
Whataburger
Jack in the Box

As far as burger quality, I'd have to say Carls Jr. and Burger King are the best. McDonalds is the worst.
April 5, 2006 7:51:15 PM

is this CPU-Z the latest version?
April 5, 2006 8:04:27 PM

Ya, I agree on burger king, but you know..

I like the french fries better at mc donalds...

I seem to have the urge to just buy the burger at burger king, then the fries and mc donalds.. Just costs me more.. gas :cry: 

Though.. I'd save on gas to taco bell, but actually have bad gas, in running for the other border. :oops: 
April 5, 2006 9:24:35 PM

Yes... McDonalds does have the best fries. Mmm...

I forgot about Wendy's; they have pretty good burgers. Fresh toppings too.

this is why smart people dont buy intel dualcores or intels :) 
April 6, 2006 6:32:49 AM

Yes CPU-Z does say "Q: CPU-Z reports my Pentium 4 3GHz or above with a 2800MHz CPU speed. A: This is the effect of C1E (Enhanced Halt State) and/or EIST (Enhanced Intel SpeedStep Technology). Load your system and you will see the frequency increase to its nominal value."

I checked the CPU temperate it was ok around 45 degrees celsius, apparently it shouldnt go over 69.8 degrees celsius. I switched off C1E (Enhanced Halt State) and EIST (Enhanced Intel SpeedStep Technology) and it still was the same.

I tried Loading my system, is making task manager reach 100% loading it enough or do I need a sort of benchmark software.

I've got a funny feeling that CPU-Z (yes its the latest version 1.33) is just not picking it up.

Does anyone know someone or have a D 830 and can run CPU-Z on it? Why is that the only "real time" CPU measurer. I downloaded the Intel one, it doesnt keep monitoring the clock speed like CPU-Z but it analayses everything and gives you a result and it said both core clocked 3Ghz, it also said my BUS is overclocking at 867Mhz, where it should be 800 I think.
April 6, 2006 7:00:49 AM

if everything is ok..and your cpu is an 830 d..your reading is normal ...
go in bios an disable EIST and C1E...your cpu-z is working perfectly.....with cpu-z your cpu goes down to 2.8...the multiplier is probably 14........EVERYTHING IS FINE...it will work at 3ghz when needed ..in load ...games etc....

Thank you, coz I think you're right. Multiplier is at 14X. Whether I disabled EIST and C1E or not it says the same. I do assume it does work at nominal speed when playing games for example like you said because absolutely everything is fine and this stupid CPU-Z has got me worrying over nothing I think.

Too all the Intel haters, I think AMD is prob better too, but the question is by how much? By looking at Tom's hardware charts I see the difference is really pathetic for all this hype about AMD. My next chip will prob be AMD unless Conroe is better.
April 7, 2006 9:30:16 AM

:lol:  there are many cpu-s which only in load run at their maximum capability......also dependes of operating sistem and software installed ..usualy EIST doesn`t need special software..like Cool and Quiet...it work by default in windows xp........these are speed step technologies meant to reduce the total power required to run that cpu...
.....no matter the speed step technology that cpu will run in full speed when needed....
my intel 630 shows 2,8 ghz...in idle ..that is 14x200 and jumps to 3ghz 15x200 when needed.......if i disable the EIST from bios it will show 15 multiplier and it will also require more power
April 7, 2006 10:07:53 AM

it's funny coz I load my sytem with for example divx encoding and a virus scan, the task manager says 60% 70% 80% 90% even 100% and CPU-Z still says 2808.7Mhz. Intel got back to me and said they're not concerned with 3rd party applications, they advised me to use their Intel Processor Identification Utility and if that reads correctly then I have nothing to worry about and it did read correctly.

What do others use to load (benchmark) their system?
April 7, 2006 10:44:09 AM

.hmmm...i`ll try that for myself.......Intel Processor Identification Utility ....
cpu-z never did any mistake also..strange......i`m a sistem builder and i use cpu-z and always worked.........i`ll try that software...Intel Processor Identification Utility ...and i`ll repply as soon as posible.......
the beauty of cpu-z is that it works with any cpu......

for benchmark i usualy use aquamark.....3dmark too but not always....
i`ll be back ...with the results
April 7, 2006 4:25:41 PM

thanks for your input fainis.
April 8, 2006 3:50:13 AM

I got Pentium D 920 2.8 GHz stock @ 2.8 GHz and CPU-Z say right... And mpjesse, You dont say anymore: -mpjesse at the end of ur posts lol

EIST enabled.

CPUZ is corect, and your CPU is 3ghz. EIST lowers the multiplyer to 14 at idle.

I get a Wopper, than McD's fries.

McDonalds gets their potatoes dehydrated. They fry them and add potato flavoring. You gotta eat fried potatoes that don't taste like potatoes unless you add flavoring. Kinda gross, huh?


wtf? u guys r off topic..
April 8, 2006 7:10:42 AM

..i`m back..i`ve checked that intel processor identification utility....and shows much as cpu-z....it also shows you the main features of the cpu....the thing i didn`t notice is the multiplier and the fsb ......

my personal preference is cpu-z
April 8, 2006 7:44:09 AM

I loaded my system to 100%, when I check CPU-Z at 100% it still says 2808.7 Mhz, Multiplier X 14. The Intel Processor Identification Utility says I'm ok at 3Ghz. I noticed that the clock speed it shows was exact same speed as it showed the L2 Cache speed, are they meant to be the same (I assume).

Everything is fine with my system, except I noticed one thing in the BIOS, when I enter PC Health Status section I noticed it says "FAIL" next to DDRV, I don't know what that means, anyone know?

Yeah, really gross!

McDonalds in Europe have really bad fries, you pick one up and it bends around to your wrist. They're not crispy at all.

Burger King and KFC however, have great fries. :D 

I would go to Burger King any day over McD's. Luckily where I live, they are both next to each other lol.
April 8, 2006 9:33:12 AM

ok...is ddr2 for sure....check the bios again ..make sure it`s ok...if fail occurs there is a problem
April 8, 2006 9:35:37 AM

...it could be a fualty psu......maybe that will explain the reading you get from cpu-z......
ot maybe the connector.....just keep an eye on it make sure....the power is ok.....
April 8, 2006 9:38:37 AM

if posible ...put the memory in other slot...i`m sure it`s ok...but you must consider everything

Gawd... that is exactly the opposite here in the USA.

Usually I get soft mooshy fries at Burger King. :lol: 
April 8, 2006 9:58:21 AM

KFC are the best in Australia.

They cook the fries seperate from the chicken, nice seasoning though.
April 8, 2006 10:46:17 AM

I have 2 X 512 Geil RAM in slots 1 and 3. You think I should swap em using 1 and 2 or something because I always get a FAIL rading in DDRV in the bios, is that slowing me down?

Hehe... Ya I'll admit I remember eating KFC fries. They even have those wedges type fries too.

But I dunno... I like McDonalds fries. :oops:

Macca's fries are oily here and small thin things.

Don't have the wedges at KFC anymore (not that I liked them), Chicken popcorn now. :D 
April 8, 2006 11:18:45 AM

all due respect, talk about this shit elsewhere coz I'm trying resolve stuff on here and I get email notification everytime there is a post then I see Maccas and KFC...
April 8, 2006 11:19:26 AM

I haven't had Carls Jr. burgers for 10 years, man I sure miss them.
As far as fries goes, I'm not really a big fan of fries. I find McD's are quite good when the are fresh, but they get soft really fast. BurgerKing has some kind of method of cooking them so they stay crisp forever, but unfortunately it also makes them taste like sh*t, I wouldn't eat them even if I got them for free. Burger King actually had decent fries before they started making these new 'King Fries'.
April 8, 2006 3:04:00 PM

With some mobos in the BIOS you can select the 14x multiplyer with EIST supporting chips. Yours must be one of them.
April 8, 2006 3:31:08 PM

I have the same problem with my T2500, it is a 2ghz dual core but cpu z reports it at 1ghz even with 2 instances of prime95 running, one on each core.

I never said that; I was unaware rolling your eyes at someone was a sign of agreeing with them. You tell me to grow up while you attack me; let's not act immature here.
