Must have - AMD 64 Dual Core X2 Driver and Optimizer

Not many people are aware that there is a Driver and an Optimizer for the AMD 64 Dual Core X2 processor. I certainly was not

Here are the links direct to the downloads.

AMD Athlon™ 64 X2 Dual Core Processor Driver for Windows XP and Windows Server 2003 Version (x86 and x64 exe) 1.3.2.16 - Allows the system to automatically adjust the CPU speed, voltage and power combination that match the instantaneous user performance need.

This driver supports AMD Athlon™ 64 X2 Dual Core processors on Windows XP SP2, Windows 2003 SP1 x84 and x64 Editions.

AMD Dual-Core Optimizer - The AMD Dual-Core Optimizer can help improve some PC gaming video performance by compensating for those applications that bypass the Windows API for timing by directly using the RDTSC (Read Time Stamp Counter) instruction. Applications that rely on RDTSC do not benefit from the logic in the operating system to properly account for the affect of power management mechanisms on the rate at which a processor core's Time Stamp Counter (TSC) is incremented. The AMD Dual-Core Optimizer helps to correct the resulting video performance effects or other incorrect timing effects that these applications may experience on dual-core processor systems, by periodically adjusting the core time-stamp-counters, so that they are synchronized.


These were found in the Drivers & Ultilities section http://www.amd.com/uk/Pages/AMDHomePage.aspx just in case the download location is moved in the future.

Does it help with FSX? I doubt it but we have more than FSX on our machines

Thanks for the links. I have a dual-core and I'll try it when I get home.

I think the Optizer makes a tremendous difference with the video.
