Turning on the CPU's second core.

[RAID 0]

OK, so I have the same problem. I have DEFINITELY got a dual-core PC (an AMD Athlon 64 x2 5200+), and yet I get the same problem. PC wizard says "Number of Core = 2; Number of Core Enabled = 1". CPU-Z just says that I have one core and one thread.

Here are some other things you might want to know:

- I'm running XP with SP2

- PC Wizard says that hyperthreading is enabled

- PC wizard has measured the speed of Core #1 as 2600 MHz, but the second as 0, or occasionally -2.11Mhz, and always measures the Core 2 activity as 0%

- My BIOS has no feature to switch on the other core, but says of my CPUs Logical - 2; Physical = 1 (I'm not sure if that's how it's supposed to be though)

- I'm running 2 x 1GB DDR2 SDRAM

The thing is, I recently bought this PC, so I sent it back to the manufacturer when I realised that all was not well, and they said that they can't find anything wrong with the PC. They sent it back, and yet I can clearly see the problems. Grrr...

I thought I would get thoughts from everyone to check that I'm not going insane. There really is a problem, right?

You're new here.. so I'll cut you a break.. it's OK to start a new thread. Try not to thread jack. Umm K?

OK, I'll start a new thread, but steady on old boy! The original problem from this thread was resolved, and my problem is a related one! It's not as if I threw the whole shebang off-topic.

Uniprocessor as opposed to dual-socket... :)

err huh???? uniprocessor or multiprocessor ACPI definitions is for a SINGLE SLOT or DUAL SLOT its irrelevant its talking about CPU CORES not sockets.....doh

as far as never buying celeron cpus....heh whatever chaps more fool you ;) when all a machine is gonna do is surf the web open office docs and play solitaire a dual core or p4d is overkill plain and simple. Id prefer to offer my customer a more cost effective machine for the dullest of uses. Its a cpu not an addon to your E-manhood ffs.

What FSB is the OPs P4D running at? 800fsb? or 533? if 533 then its a poor-yielded P4D crippled to run single core CPU (one way to find out is remove the heatsink and see what the stamp says on the CPU shim)

Hi

Just going from memory but the celeron D series of CPU from Intel are actually Pentium 4's based on the prescot core.

So it would have had hyperthreading 800Mhz FSB and 2MB of cache if it was still a Pentium but its not. But because its a budget CPU they dissabled hyperthreading and nearly all of the cache on the CPU.

Long story short you have a single core CPU with Hyperthreading disabled! (Which is not neciserally a bad thing ;-)

Sorry

I'm amazed at some of the comments here :laugh:

Celerons do NOT have two cores.

Oh really? Intel would beg to differ:

Newegg would too:

Yes the OP has a single core but there are dual core celerons!

FYI - dont ever buy Celeron's. i dont care who the PC is for.

Not with the new ones. The Core based Celerons are uber clock stripped Core 2 CPUs, 50 bucks for a dual core that I can overclock to 3GHz, I won't pass it. :p

That didn't start shipping until 20th Jan 2008, whereas all the posts made here were 22nd Dec 2007 or prior

Yeah there's really no way the OP's CPU can have a second core enabled. It's umpossible. It ould be a bad Pentium D made into a celeron, but if you could somehow turn the other core on it would lead to bad things.

True, didn't see this thread was over a month old, but!

Post date of December 7, 2007, so they were still known before the Jan 2008 ship date! :)
