Core i7 920 not working properly

i was looking at my settings for my computer....
I have an i7 920 2.66 CPU
1 GEFORCE 9800 GT
P6T Deluxe motherboard
3 Gigs of RAM...
I noticed, even with small tasks. ie. Opening Firefox, running StarCraft, or Playing crysis, my computers CPU usage is at 100%.....


So I ran a hardware diagnostics (I work at a computer store)
And on my Day 1 Diagnostics...
It read
Processor 0
Working Correctly
Processor 1
Working correctly
Processor 2
Working Correctly
Proc. 3
Working
Proc 4
Working
Proc 5
working
Proc 6
Working
Proc 7
Working....



I ran a diagnostics today...

Processor 0
Working....

That's it...
Why is this...
Then I ran a benchmark. Now my i7 is running 7thousand points lower than it was originally...
What is going on?

Turn of the EPU on your board and see what happens. It could be that IT isn't working right. And also Crysis isn't a small task. :) 

I have heard several people mention having problems but there have been several more saying they are great. Intel has already said their will be predaccessors to the i7 line (925 or 930, 950, and 975) and they will discontinue the current line. So look for that in the near future. This is one reason why I am usually not an early adopter until I hear what's the deal with the product.

I did this.. It did not work.

Start with using task manager or another utility to see what is using 100 percent of the cpu. Also I dont know diagnostics you ran but start with cpuz and temp monitors. Make sure all the speeds/volts/temps are normal.

Then you can run stabilty checks such as prime95/orthos/memtest...etc.

Getting 100 percent cpu load for no good reason is usually a software problem(windows/malware/hung app).

Maybe you're running some apps. in the background without knowing. You know, FAH or something like that. Go to Task Maager > processes > sort by CPU load and see which one is on top.
April 19, 2009 4:52:25 AM

the one on top is a program called aacenter.exe...
I called ASUS they said I can just remove it, but i've done detailed searches through my computer.... I cannot uninstall it
April 20, 2009 12:29:15 AM

see thats when the computer is idle... when I open anything..
Be it Crysis... or Starcraft...
My computers processing power is maxed out to 100%
April 20, 2009 12:29:35 AM

infact.. my last post made my CPU jump to 48%
April 20, 2009 12:44:07 AM

There's something wrong. See in my shot? The system idle process is at top. Is shows you how much % of CPU is free. I can't find that on yours. It has to be on top. I thought you said it was 50% at idle?
April 20, 2009 1:48:38 AM

Nope, no problems with 50% idle....
When i'm not doing anything my CPU is at like 1-6% on average.. But when I open ANY PROGRAM.. it shoots to 100% and I have to wait for small or large programs to open.
be it firefox, Starcraft, or Crysis/.

i'm about to upload my original settings and what I just scanned.
April 20, 2009 1:56:20 AM







this is my test I did about 3 weeks after I built my computer

this is the one I did today

Why do you run such memory configurations? 2+2+1 , 2+1 etc.? Anyway, flash a newer BIOS and try.

Could this have something to do with SW Single Processor Mode?
April 21, 2009 12:21:25 AM

I have two 2GB sticks in there, but for some reason it only reads 3 or 2.5
April 21, 2009 1:11:16 AM

That's right. And why do you use dual channel with i7?
April 21, 2009 1:39:39 AM

I do? I had no idea I did.. What does that mean?
April 21, 2009 5:25:34 AM

In simple terms, it means you use 2 or 4 sticks of RAM. i7 works better with three. You could try these:
3 x 1
3 x 2 - this would suit you best as you already have 2 sticks. Make sure they match
6 x 1
6 x 2
April 21, 2009 2:59:16 PM

alright one second let me change the configuration with the sticks and I'll be right back.
April 21, 2009 3:15:34 PM

Also check the BIOS. I dunno about i7, but my mobo has the SW Single Processor Mode which uses just one core. Make sure all settings are right. If the problem is still not solve, flash a newer BIOS.

IS your OS 64 bit? otherwise it won't show all 4GB.

FLASH your BIOS. I have an ASUS P6T and I've flashed it 2 times in a week because of updates. The x58 chipset is new and has... a few issues.
April 23, 2009 12:56:15 AM

Go to the ASUS site. There will be BIOS updates for your board as well as instructions on how to flash the BIOS.
April 23, 2009 3:06:04 AM

Alrighty, I did this. Its sitll only showing one processor.
I called ASUS and got an RMA, they said it could possibly be the board...
Hopefully it is.
If its not the board, is there any other hardware that could be the issue.
I've only been having this problem since we had a power surge randomly one day during a nice day.
Ever since the computer has been running less than full standards.
April 23, 2009 3:06:40 AM

btw rags, you've been a great help.
Hopefully this board will be the fix of all the problems.
April 23, 2009 5:02:01 AM

What PSU do you have? A poor one could be the reason. In that case, other components might have suffered as well. Anyway, see if all 8 are recognized after RMA. Or maybe your PSU doesn't have enough wattage.
April 23, 2009 4:24:05 PM

well, I solved the problem.
I ran that program again, and I accidently exited out mid scan.
Anyways I went to turn on my computer this morning, and it said my boot up drives couldnt be found.
So I put in my vista disc. Ran a repair on the OS
All of my CPU's 0-7 are working and functional.

YESSSSSS!!!
April 23, 2009 4:58:31 PM

That's strange. How could a Vista repair solve your CPU being recognized?
April 23, 2009 11:32:59 PM

I have no idea. I just ran crysis. my cpu doesnt exceed 14 percent usage... EVER now.

I can play starcraft and it doesnt exceed 2%
Firefox no longer slows down the computer.

Heh :) 

Yeah, the i7 is amazing. I love mine, although I definitely go WAY over 14% usage fairly often. I don't often load it fully, but I am at 80% or so with some regularity.
April 25, 2009 2:08:07 AM

I just wanted to say thanks to every one to helped out especially rags, you guys have been great. Thanks for all the suggestions.
April 25, 2009 1:53:49 PM

Yeah, well, I find it hard to believe that Crysis uses just 14% of the i7. That's a little low. Shouldn't it be over 50%, especially a 920?

Resetting HAL configuration maybe.

No. To use 50% of an i7, you need 4 threads fully loaded. 14% is a single thread, fully loaded. Therefore, Crysis is loading a single thread to full load. Something else that is optimized for multi core CPUs such as FSX would probably load it quite a bit higher.

Well i'm not lying to you rags.. I have nothing to gain from telling you fake CPU usages.
April 26, 2009 2:41:12 AM

Its not that. My Q6600 uses more than 50% across all cores and I believe Crysis is multi-threaded?

@endo Are those reading CPU usage readings or core usage readings? Could you tell what your core usages are using CoreTemp?

April 26, 2009 3:03:38 AM

Crysis does load balancing but is not really multi-threaded. If it was you'd see greater improvements from going from 2 to 4 cores, whereas you only see a major improvement going from 1 to 2. Compare that to video encoding software where core scaling (or rather thread scaling) can be quite close to linear from 2 to 4 cores.

I suppose something could have screwed the processor driver in the OS. If it was just one core that was functioning, then it follows that Vista was running in compatibility mode. The re-install/fix OS detected the hardware properly, including the i7 and installed/repaired the driver, therefore bringing all the cores up again.
May 1, 2009 3:52:44 AM

CPU usage readings...


0-8 combined do not use more than 14-15 percent total.
May 1, 2009 2:28:19 PM

I said individual cores, possible the highest ones.
May 13, 2009 6:32:11 PM

I checked it while running crysis...
Only one thread out of the 8 is at like 75 to 90 percent while running, and ht eother don't really exceed 1-5 percent.
