Missing Processor Cores

Hello Experts

My system consist of 2 units Dual Core Xeon's Running at 3.0Ghz, 2x2Gb Ram, Dual DVI 512Mb PCIe x16, 6x Sata II Drives, Huge 1010 Wat Power Supply.

System boots fine, all 8 Cores (4 physical + 4 Hyper Treading) are running well, even under extreme stress like heavy video rendering for long periods no visible problems.

The system can run for 1 hour or 3 days & nights in a row, after it runs warm / hot, and is rebooted only 4 cores show up in the system (4 are gone)

The bios shows various errors on processor #2 but not consistant same number, it varies but alway processor # 2.
Even after the processor #1 and #2 are physicly swithed the system only shows 4 cores.

When system is used with either one processor is shows no problem, always 4 cores, even after running warm / hot and rebooted.

After the system is shut off and allowed to cool for about 1 hour is runs again on all 8 cores, for hours or days, as long there is NO reboot.

This problem is driving me nuts, I have changed to other Display cards, Ram has been changed, a power conditioner has been bought, a Huge APC smart ups to eliminate power supply problems.

Eventually the Motherboard has been exchanged, still the same problem.
I did run the processors one at the time and also swapped their physical position.

I'm lost for idea's and I need help for the first time building a new system.

Any suggestion's from the experts ?

Best regards Tony Dekkers.

    It's build in a 4U Extended Server casing c/w with 1x 12 Inch fan to cool the 5 Units Video / Data Drives, 1x6 Inch fan to cool the boot drive, this all located at the front.

    Then of course the 2x Xeon have their own intel copper heat sink c/w 2x fan bios controlled (set to high performance)

    The power supply has 3x 6 Inch fans, the back of the casing has 2x 6 Inch fans, more than enough to keep steady airflow through the system.

    My only concern are the 2 chipset heat sinks and the System ram which to run rather hot (no fan yet, planning to) and the display adapter also without fan.

    My system operates in Asia on the island of borneo, therefore the temperature is a bit high, 33 in day, 28 Degrees at night, thats why all fans are running full speed except the processor fans, they are bios controlled and go to almost full speed every now and then while rendering video, otherwise (normal operation - no heavy rendering) they run pretty silent.

If you are runnung Vista HP 32 bit (maybe Ultimate also), the problem lies with Vista. I had the same problem. I installed Vista Ultimate 64 bit and presto! Problem solved.

Indeed I think I have to study all the cooling solutions that are available to solve my problem.
I also send a mail to Intel support, lets see how good their support is for server / work staions, but as a end user I don't even expect a reply, time will tell.

As I live on a Island and the computer shops over here only cary very basic stuff I need to get all my info from the web, and I have burned my wallet more than one before, so I will take my time before ordering anything.

If users with similar Xeon sytem changed their coolers succesfully i would appriciate it if they would post their product recommendation here.

Nice system, what kind of cooling do you have in there? How many fans etc...

Posted on Jan 11, 2008

  • Douglas Green Jan 11, 2008

    from some of the reviews i have read them heatsinks are really cheap, only a chunk of copper with weak fins and the fan is loud. I bet this is the problem here. I would replace them heatsinks with a better aftermarket heatsink make sure that when you replace them you fully remove the adhesive using (90% ispropyl rubbing alcohol) from the processor as best as possible and use a better adhesive. But do this with caution because you can mess up the processor if removed incorrectly.

Laptop doesnt boot when multi core processing is enabled


By multi core I assume you mean when enabling all of the true processor cores. In your laptop's case it's a Dual Core processor which means there are only 2 phyiscal cores and does not contain HyperThreading Technology (HT Technology) which enables "Virtual processor cores"

Could be caused by a couple of things:

1. Your processor doesn't support multi-core processing which is a possibility given there is no HT technology for your CPU. In which case there is nothing to fix. Even though the BIOS may have this option. You can check to see if both cores are enabled when you have multi-core processing disabled; In windows right click on your taskbar and click on "Task Manager" Click on the performance tab. You will want to count the number of processor displays you see. Refer to this to see what I mean:

f6c39969-f900-4d19-bf1f-64040578cc05.jpg

b129bf4a-74da-49fb-868b-3bfda7229b97.png

The reason I have 8 CPU displays is because I'm running an i7-3820 CPU which supports HT Technology; So I have 4 physical processors cores and 4 virtual processors cores (created by HT Technology architecture)

2. You are running Core2Duo CPU with dual physical processors and have disabled 1 of the 2 cores because your laptop won't boot. This sounds more like you need to update the BIOS on the motherboard or maybe a bad CPU might be the cause as well.

Hope this helps.

Can i make a dual core run like a quad core, or add cores with out changing mother board?


You may be able to install a quad core processor on your motherboard, will need the model to check.
You can't make new cores out of nothing though.

Printer stop printing ink


If you can't even get ink to come out for a nozzle check, there are two different things you can try. Update the Epson Firmware, or you'll have to change out the motherboard.
