Xeon® Processors

[tinkerstoys]

First the CPU has no pins but flat contacts. The OS system info shows 2 cpus in the right type and speed as well as the ram in the right size. Bios sees the 2 cpus also.

enter task manager, if it also shows 2 CPU's + hyper-threads then i fail to see what the problem is unless again you are not posting critical information, making me take guess that it's only boinc not showing the proper cpu count if so i suspect boinc was installed/setup when there was only one cpu installed and needs to be reconfigured to reflect the new cpu count

[tinkerstoys]

First a personal Thank you for all the help. And what critical information are you needing? I am not trying to hide anything. I when to the Bios (version 03.61) and do see the Boot Block Cate of 11/10/09 so I know it will take the 5600 series CPUs. It also sees the right number of CPUs, type (X5690), and speed along with the ram in speed, size, and location. Task manager shows all CPUs working when the SETI program is running. See pic.

Now after reloading the SETI program it stills only shows the 12 processor even with the task manager saying all 12 are running. Why is SETI not showing up the threads on this machine like it is on the other? I see no setting for the CPU count to be changed.

sorry, but again no visable picture is attached

and once more i must ask since you have not answered the question how many cores do you see in task manager

12 or 24 cores? the comment (Task manager shows all CPUs working  does not actually answer this question)

if task manager only shows 12 cores, then hyperthreading is disabled, check the bios settinges

also, if you reread my previous post on the checking the cpu SOCKET pins comment, nowhere did i tell you that the pins are on the cpu., i'm quite aware that modern cpu's only have  small flat pads for the socket pins to make contact with

last, i'm not acusing or implying that you are hiding anything rather that you are failing to provide nessary information,.... you have to keep in mind that i'm not there when you do something, and i also can;t see the hardware or software in use

as such all i can do is make suguestions based on the information you provide

[tinkerstoys]

To you my learned friend as you can see we got it. The hyperthreading was disabled turned it all on in the BIOS and now it shows 24 processors. Again Thank you. There were 2 places in the Bios setting that needed to turn on to get this to work.

It has 96 gig of ram, 1100 watt power supply, high end HP CPU coolers. Bios is up to date from HP. Bitcoin political

To Tinkerstoys....... what exactly are the two things you needed to change in BIOS to get hyperthreading to work properly.

This has been a bit of a recurring issue, and you can help others by taking a couple of minutes and stating what you actually did to reliably get this going.

Thanks much to you and DGroves for the help.

the only three bios settings that relate to this is:

Hyperthreading  (ON/OFF) Provides processor parallelization such that the operating system treats one processor as two.

Active Cores   (1,2, or All Cores)—Selects a single core, or multiple cores per socket.

(Not available on some configurations.)

Limit CPUID  Maximum Value to 3 (Enable or Disable)—Sets the number of allowable CPU ID

resetting cmos, will reset all bios settings back to defaults, even if a custom bios settings default has been set

note that the default bios settings can be customized and saved as the default, so simply selecting bios defaults may not actually load the factory defaults, but the customized ones if unsure do a cmos reset

I think that  DGroves has said it all. I don't what else to add but reboot a couple of times to get it all picked up.
