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

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! :)

    • Incredible deal gets you free NVMe 512GB SSD with AMD AM5 B850 motherboard for only $150

      Incredible deal gets you free NVMe 512GB SSD with AMD AM5 B850 motherboard for only $150 by Sayan Sen Earlier this week we covered the story of an interesting PC case wherein you can build two full-size computers inside it as in it can house and run an AMD and an Intel system simultaneously. Speaking of building PCs, these are hard times to make one for sure as prices are often very high except during flash sales or discounts. If you are in the market for a 1080p gaming PC then Nvidia's 8GB RTX 5060 Ti is currently on sale for just $330 and you get the latest James Bond game too, for free. Speaking of which, right now there is another incredible sale going on as we can get a free 512 GB NVMe SSD from TeamGroup in the form of the G50 alongside the purchase of an AMD B850 socket AM5 motherboard for only $150 (purchase link under the specs table down below). Getting an AM5 motherboard now in 2026 will be a wise investment for sure, especially since AMD confirmed its commitment to support the socket till at least 2029. The MSI PRO B850M-P WIFI is a micro-ATX motherboard that is compatible with AMD Ryzen 9000 series processors. Since it is AM5, the motherboard works with DDR5 memory and includes MSI’s Memory Boost technology, along with EXPO and XMP support. Connectivity features include built-in Wi-Fi 7 paired with a 5G LAN solution. The board offers a PCIe 5.0 M.2 slot with MSI’s EZ M.2 Shield Frozr II thermal solution, that is said to help maintain SSD performance by providing ample cooling against overheating. The technical specifications of the MSI PRO B850M-P WIFI motherboard are given in the table below: The free TeamGroup T-FORCE G50 NVMe SSD is a PCIe Gen4 and as such it promises to deliver sequential read speeds of up to 5,000 MB/s, helping accelerate game loading, file transfers, and everyday computing tasks. The SSD features an InnoGrit controller and SLC caching technology to support consistent performance. An ultra-thin, patented graphene heatsink is included to aid in heat dissipation. The NAND flash is based on TLC which means it has plenty of endurance up its sleeve. The random performance may not be as amazing as other drives with DRAM though. Still it should be very good since it can access system memory via HMB to use it as its DRAM cache. The technical specifications of the TeamGroup 512GB G50 NVMe SSD are given in the table below: Get it at the link below: MSI PRO B850M-P WIFI AM5 AMD motherboard + Team Group T-FORCE G50 512GB SSD (free gift): $149.99 (Sold and Shipped by Newegg US) This Newegg deal is US-specific and not available in other regions unless specified.

    • RapidRAW 1.5.7

      By Copernic · Posted

      RapidRAW 1.5.7 by Razvan Serea RapidRAW is a beautiful, non-destructive, GPU‑accelerated RAW image editor designed for speed and simplicity. It uses a lightweight (~30 MB), efficient code base built with Rust, React and Tauri. Ideal for Lightroom workflows, it offers rich editing tools—exposure, contrast, highlights, shadows, whites/blacks, tone curves, HSL mixer, dehaze, vignetting, film grain, sharpening, clarity and noise reduction—processed in real-time on the GPU. Features include intuitive masking (brush, linear, radial, AI-powered subject and foreground detection), generative edit layers (via ComfyUI), 32‑bit precision, and full RAW format support through rawler. RapidRAW also provides library management (folder navigation, ratings, metadata, EXIF viewer), batch operations, export presets (JPEG/PNG/TIFF), sidecar editing (.rrdata), undo/redo history, customizable UI themes, smooth animations, resizable panels, and preset copy/paste. A modern high-performance Lightroom alternative with polished UX and creative tools, RapidRAW brings powerful photo editing to photographers seeking speed, responsive GPU feedback, and streamlined workflows. RapidRAW v1.5.7 release notes: This update serves as a direct follow-up to the core architectural migration introduced in v1.5.6. While the transition to a more modular state management system marked a significant step forward for RapidRAW's stability and long-term maintainability, it also introduced several edge cases and regressions within the library and editing workflows. This release focuses on addressing those issues, with a particular emphasis on a complete overhaul of library performance to ensure smooth and responsive browsing following the refactoring. It also resolves inconsistencies in the copy-and-paste workflow and expands RapidRAW's accessibility by adding support for eight additional languages.
