Where's my other core gone?

Guys,

After sorting everything out on my rig I noticed that the task manager is only showing a single CPU performance graph, as it is a E8400 and it used to have two graphs...I would expect two graphs.

The Task Manager view options are set correctly, one graph per cpu, the Device Manager recognises the two CPU's and all my drivers are up to date.

Any ideas on how to get the Task Manager to recognise the other core? :confused:

I think it could be a bug with Windows if you swapped from single to dual core without a repair/reinstall?

Worth updating motherboard BIOS to latest as well.
 
If in the course of "sorting" out your PC you dabbled with BIOS settings, you may want to take a second look at some of them.

I did something similar a month or two ago when I went through my BIOS "tuning" up some settings.
 
The Windows system is a clean install, SP3 + latest updates.

BIOS has factory defaults apart from RAM & NB Voltages and SATA-2 settings.

I will update the bios and see if that helps.

With regards...
ACPI Multiprocessor HAL

How can I check this and get it?

Oooookkkkkkaaaaayyyyy.....

That didn't go as smoothly as I had hoped.

I forced the update so that it uses ACPI Multiprocessor HAL, rebooted and everything was fine.

After a while I decided to play a game, it wouldn't start - complained that it had ran out of memory....but I had over 2.5GB available...

So did a reset, everything came up, started the game, browsed the web, synced my iPod, everything was fine.

Then when I tried to open another program Windows stopped it opening with a DEP message, though I'm glad to see Windows security can stop these dangerous programs, explorer.exe in this instance, I was getting somewhat frustrated.

Did another reset, checked the BIOS was OK, and now Windows won't boot again....it gets as far as the Windows loading screen and resets.

Any thoughts on a fix for this....do I need to up the voltage to the CPU, more voltage to the RAM?

Looks like a BIOS update sorted it, Flashed to the latest BIOS and everythin is good.

Fingers crossed, that's the last of it.
