- Load optimized defaults in your BIOS and do not modify memory settings
- set your memory settings in the BIOS less aggressively and test
- make sure you have an adequate power supply
- disable or enable AGP fast write and test (this has worked for some people)
It’s a memory timing problem that only happens when the RX55 register is opened. Some motherboard manufacturers have already released new BIOS that have the register closed. In other instances, this patch is needed.
To install it, unzip the file and run the setup.exe Do not run the setup from the compressed folder.
So what does it do? It closes the RX55 memory register in BIOS. The RX55 register's official name and function is Memory Write Queue (MWQ) timer. The MWQ timer is actually a timing device included in the memory host controller to prevent write data being held in the memory queue too long. After the data has been in the queue too long it times out. This timed out data is then given a higher write request priority. Now that might sound nice – a bit of extra performance BUT the procedure fails when overloaded. 3D games and Win XP put too much load on the memory queuing timer procedure. The nVidia new driver exaggerates the problem even more as the driver enables nVidia cards to use even more memory than previous driver versions.
