Turning on the CPU's second core.


Recommended Posts

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:

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

You learn something new every day :)

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

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! :)

    • Apple is expanding Private Cloud Compute beyond its own data centers by Pradeep Viswanathan At WWDC 2026, as part of the improved Apple Intelligence capabilities, Apple today announced that it is expanding Private Cloud Compute (PCC), its privacy-focused cloud infrastructure for Apple Intelligence, beyond its own data centers for the first time. Private Cloud Compute was designed to handle Apple Intelligence requests that are too complex to run fully on-device. The PCC system does not store user data and does not allow Apple or anyone else to access user requests. Last year, Apple also expanded its Security Bounty program with rewards of up to $1 million for researchers who could find serious vulnerabilities in PCC. Until now, Apple's PCC data centers were using Apple's own silicon. As part of the expansion, Apple is working with Google and NVIDIA to run new Apple Intelligence workloads on Google Cloud systems powered by NVIDIA GPUs. Apple will be using this new infrastructure to execute more demanding AI tasks while maintaining the same privacy and security guarantees of PCC. The new implementation uses NVIDIA Confidential Computing with NVIDIA GPUs, Intel CPUs with TDX, and Google’s Titan chip. Apple says it has worked with Google to build additional protections beyond a traditional confidential computing deployment. Despite the expansion to third-party data centers, Apple claims that its core PCC requirements remain unchanged, including stateless computation, no privileged runtime access, non-targetability, and verifiable transparency. The company highlighted that it will continue to control the PCC software stack, and Apple devices will only trust PCC software that has been cryptographically approved by Apple. To take security to the next level, Apple mentioned that it is maintaining an append-only ledger of Google Cloud hardware that is part of the PCC fleet. The company claims this will help reduce the risk of supply chain attacks. In addition to AI infrastructure, Apple also worked with Google to use technologies behind the Gemini family of models to build the next generation of Apple Foundation Models to power Apple Intelligence features across on-device and cloud workloads. As expected, for more demanding AI tasks like agentic tool use and complex reasoning, Apple will rely on the expanded PCC infrastructure running on Google Cloud. The expansion of PCC on Google Cloud will gradually ramp toward the full set of protections during the summer preview period. As before, Apple will also publish binaries for public inspection, provide research tooling, and give researchers access to live PCC nodes in research mode through the Apple Security Bounty Program.
    • my problem with outlook (new) is that it connects only to outlook.com. all connections to external providers goes through there. Got your mail server and want to use imap directly? no way... it adds a connector on outlook.com. last bug; if your email on an external provider if the same as principal email of your microsoft account, it doesn't work...
    • It's the only reason I finally have an iPhone (for work) and enjoy using it so much that I'm tempted to move from android next time I need to replace my own device
    • So is Russia, China, Iran, North Korea, just to mention a few. What's your point? Everyone is a threat from their enemies' perspective. I'd say that Israel is only a threat to their immediate enemies like Hamas, Hezbollah and the Iranian regime, not to anyone else.
    • The government is not the good guy either. You propose 99% of people require that the government overreach and govern their freedom of information and privacy, while ignoring the government is made up 100% of people, of which 99% are (as you described) brain dead. You can't have both. The reality is Signal is absolutely right and the government is doing what it has always done. Ignoring that we are their boss and grabbing all the power they possibly can to make sure we aren't. Your (societies) ###### parenting is not reason enough as to why I can't have a safe platform for my data/information. Thinking the government is helping is precisely what they are targeting psychologically to take suckers like you for a ride. "Think of the children" was, has, is, and will always be a mechanism of control. In the rare occasion it's actually essential the mass consensus has always been there and it doesn't become a debate.
