Hi Dudes
I have been in battle with this problem for 3 weeks. It really got frustrating. But finaly i found the Solution . Try´d and tested.
Everyone using a AMD X-2 should run this routine.
The system will perform smooth as silk.
My system performs as a rocket now. (AMD X-2 4400+ and a ATI EAX1900XTX ) Even the anoying GTR problems are gone now.
Follow these instructions.
PLEASE BACKUP YOUR REGISTRY FIRST!!
1 - Install the amd drivers, download it from here...
http://www.amd.com/us-en/Processors/..._13118,00.html
2 - read this website and download the X-2 hotfix
http://support.microsoft.com/?id=896256 http://www.amdzone.com/files/WinXPdualcorehotfix.exe
3 - Edit your registry to enable the HOTFIX, follow these steps.
1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Right-click HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager, point to New, and then click Key.
3. Type Throttle for the new key name.
4. Right-click Throttle, point to New, and then click DWORD Value.
5. Type PerfEnablePackageIdle for the value name.
6. Right-click PerfEnablePackageIdle, and then click Modify.
7. In the Edit DWORD Value box, type 1. In the Value data box, make sure that Hexadecimal is selected, and then click OK.
8. Quit Registry Editor.
4 - Make sure your BOOT.ini has this command in it,
/usepmtimer to check, right click on My Computer go to properties, click on the ADVANCE tab, then under startup and recovery click on settings, then click on EDIT....make sure your boot.ini looks like this
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer
Finally your done, if anyone has any questions feel free to PM me, hopefully this will be a help to alot of people.
OK, since some people switch to single core after having issues with dual core, here is a simple way to remove the Hotfix and drivers.
1 - Uninstall the Hotfix, go into ad/remove programs, click on show updates and remove update numbered KB896256
2 - Reverse the registry entry.
3 - Uninstall the AMD drivers.
4 - Done.
