 Posted: Sun Dec 14, 2008 10:07 am Post subject: only 1 core running out of 2 |
 |
|
Hi guys/girls need help i just brought a Pentium D 805 cpu and only one core is running out of the 2 for some reason according to my PC wizard 2008 it says its not enabled i was wondering how to enable it can you please help.
Its my first multi core cpu I was running a Celeron D 3.06ghz before it and all I've done is switched them over for the dual core 2.66ghz my mobo is a ECS/SiS661GX-M7
533mhz FSB
according to the ECS web page that's the biggest cpu i can put in the board I just spent a year trying to find it.
Its not brand new but its fully refurbished and other than that its working and I did score 3500 PC Wizard benchmark instead of the 3000 I was getting with the other CPU. 
P.S even task manager is only showing one core not two in the Performance window and it set to one graph per cpu. |

Have you upgraded the CPU without reinstalling windows?
In some cases windows fails to identify the new dual core CPU correct if it was installed on a single core PC. In this case it should be reinstalled.
IMHO you should try to boot a system from a live CD first. Many Linux versions and also Bart PE Windows are suited.
If these systems detect both CPU cores - your windows is the culprit. 
In some BIOS versions it's possible to activate/deactivate CPU cores one by one. I have a quad core CPU and I can deactivate every single core I desire. |

found that cpuz program ran it and this is what it says

but that is not what is written on the CPU it self but that still dosen't explain why its only running one core there both D 805 ones just 05A the other is 05B |

@Qwerty
I would reinstall my windows but its not proper copy and requires me to format the drive so it comes up genuine but I have thought about it I'll like to know before it comes to that point.
If you have any other ideas to try first
and I'm runnig the latest drivers for my bios and mobo that I can find though they are pretty old 16/12/2005 but there is no more after that.
My bios doesn't let me change cores just the x rate which is to 133mhz-20x even if I change it to 14x it doesn't change when the machine boots up it still says 133mhz-20x but it dose say that it has to 2cpu's, so you maybe right about windows it still doesn't explain why pc wizard says this

and my tuneup utilities says this

| st lest they all say smithfield and not malay but on the cpu it self it says malay 05A but cpuz and PC wizard say bo which would me it's 05B don't know about tuneup it doesn't say for it which you can see from the pics |

Of course I understand that reinstalling windows is a pain in a$$. 
That's why I said you should try to boot a live system from a CD (see my post above).
In this case you will get another OS up and running without disturbing your windows on the HD. |

Smithfield is code name for Pentium D 800-series CPU-s
Malay is country of manufacture
05A and 05B is "Platform Compatibility Guide"
| Quote: | Platform Compatibility Guide
To reduce confusion in proper motherboard selection, Intel has created a compatibility naming convention called, Platform Compatibility Guide. "05B" and "05A" will be the first Platform Compatibility Guides for the Pentium D processor. (Future specifications will use similar Platform Capability Guides where the first two digits represent the year the Guide is introduced and the 3rd digit stands for the market segment. "A" applies to processors that fall in the Mainstream 2, 1 and Value market segments; where "B" applies to processors that fall in the Performance and Mainstream 3 market segments. Intel product dealers can view the Desktop Processor Roadmap (PDF) which shows which processors fall under the various market segments. Additionally, Platform Compatibility Guide information for a specific processor can be found on the S-Spec Reference Table and the Processor Spec Finder)
All of the Boxed IntelŪ PentiumŪ D processors in the FC-LGA4 package will have markings on the box with either, "Platform Compatibility 05B" or "Platform Compatibility 05A". See figure 4 for an example of how processors will be marked.
Motherboards that support processors with the Platform Compatibility Guide (PCG) 05B specification will support processors with the PCG 05B and 05A. In other words Motherboards designed to PCG 054B are backwards compatible with 05A processors. Motherboards that only support processors with the PCG 05A will not support PCG 05B processors. These motherboards have been designed to provide customers with a lower cost platform.
Platform Compatibility Guides do not promise compatibility. Platform Compatibility Guides specify likely motherboard compatibility with processor electrical requirements. Compatible BIOS, drivers, hardware, and operating system are required.
Additionally, a BIOS upgrade may be required in order to properly recognize and initialize the latest stepping of the Pentium D processor. Motherboards must also meet the electrical and mechanical specifications of the Pentium D processor, as documented in the Datasheet. Intel tests motherboards for basic compatibility and lists passing boards on the Tested Motherboard List for the Boxed Intel Pentium D processor. |

@Elar
there is only one 533mhz FSB and its 05A or other wise my mobo wouldn't run it at all which is good cause the cpu only comes in the 05A range and those ones are BO stepping so it will run on my mobo I think I'll have it tested at a shop first to see if its all good cause I bought of a eBay shop and then I think I'll face the music and do a clean install of my windows if it turns out all good because its all so starting lock up my machine now when its been running for an hour or so which might be because its not running right in windows and it seems to be running hot to though I'm using the same heatsink and fan that was cooling my Cel D 3.06ghz cpu its up at the 70 degrees mark which can't be good for it though it says 64.1 degrees on the spec page of the intel site I don't know if it is it's max temp or average running temp for it though |
