Optimize XP for Dual Core


Recommended Posts

  • 2 months later...

Anyone else tried this on a Intel Pentium D??

This "dual core" fix is not for improving dual core performance, but for preventing crashes caused by dual core CPUs (mostly from AMD) when they change power-saving states. AKA change their CPU operating frequencies to save power. It does nothing to improve performance, XP already schedules tasks across cores without the fix.

You DO need the fix if you are getting crashes in XP because of your dual core CPU.

As for the difference between Vista and XP, Vista is running so many craplets in the background it needs enhanced dual core support just to run as fast as XP. :| Compare Vista performance on single and multi core CPUs if you think this is a joke.

Here's a good article about what this XP dual core issue is really about:

But then why are people getting performance increases??

This guide is not for XP 64-bit btw. The update doesn't apply (and there isn't a 64-bit version, I checked) and the reg entries aren't there in the 64-bit version too. Just wanted to let you all know ;) Thanks for the guide tho, I did hear it's done wonders for my friends.

This is what I read of the MS website, here: http://support.microsoft.com/kb/896256

SYMPTOMS

Computers that are equipped with multiple processors that support processor power management features, such as Advanced Configuration and Power Interface (ACPI) processor performance states, require Microsoft Windows XP Service Pack 2 (SP2). Additional updates are available to optimize performance and behavior on computers that are running Windows XP SP2. Without these updates, computers that are equipped with these power management-capable, mobile, dual-core processors may experience decreased performance or unexpected behavior.

That red word leads me to think that there isn't any performance to be gained by doing these steps.

i dl'ed the ms fix and i got an error. I have a p4 w/HT, created the registry key and modified the boot.ini

i'm actually gonna restart right now to see if there's a difference.

when i built my bro's AM2 Rig, i believe i installed the AMD drivers, the Windows fix, AND the dual core optimizer (one game even required it). so i dont believe its harmful. every game runs fine on it, except he's having issues with steam games (online only). Wish i knew why.

    • JetBrains is working to cut false positives in RustRover 2026.2 by David Uzondu Recently, JetBrains released the fifth EAP build of its dedicated IDE, RustRover 2026.2, bringing improvements like a Run gutter icon for criterion_main! macro benchmarking and a feature that alerts you when there are unused traits in your current scope. Now, the company is out with a blog post addressing one of the "most common" complaints from users: false positives. In RustRover, a false positive occurs when the editor incorrectly highlights something as an error even though the project compiles and runs successfully. This mismatch flags a gap between the IDE's internal intelligence and the actual compiler. When the editor flashes red warnings over perfectly valid code, developers lose trust in the tool, which stalls momentum. Traditionally, RustRover runs cargo check to detect compiler errors and warnings, but it also relies on its own code analysis engine to power real-time features. To provide quick feedback, this engine parses your source code into a syntax tree while inferring types and resolving names as you type. Because this engine must work on broken, half-written code and react instantly, its logic sometimes diverges from the compiler's, producing false positives that do not exist in the compiler's eyes. JetBrains said that it has a "dedicated task force" focused specifically on identifying and fixing false positives by analyzing user reports and examining large-scale open-source projects. To speed up this process, the team built an internal system modeled after Crater, the famous Rust project that compiles and runs tests for every single crate published on crates.io. This automated pipeline compares the diagnostics from RustRover's analysis with actual compiler output to catch discrepancies before they reach users, ensuring smoother workflows. RustRover, for those who're unaware, is a dedicated IDE designed specifically for Rust developers. It's been around for a couple of years now, providing features like built-in debugging via LLDB, seamless cargo integration, advanced macro expansion, and HTML support. JetBrains distributes the app under two licensing models: a paid commercial subscription and a free option for non-commercial use.
    • Last year I bought the 2TB variant for $114 on Amazon. That's crazy that the 1TB is now 67% more expensive for half the storage, even with the newer T9 already on the market. And that's considered a good deal.
    • You can disable all non needed features from Brave. There is also Brave Origin which removes them entirely and it is free for Linux.
    • I wish I could use Brave but the tab suspension feature is horrible. It doesn't suspend them like Edge does. Even after 2h open with 70+ tabs (same as Edge), it has 2GB more consumption than Edge for no reason.
