Download wpcrset. Use Sandra to measure whether each modification you make to chipset settings increases memory performance. Finally, have a piece of paper and a pencil ready to record exactly what you have done. This step is actually the most important one, so don't neglect it!
After downloading the two applications and installing them on your system, you are ready to begin. First, reboot your machine, and without running any other programs, open Sandra Run each test in the same order. Now reboot your system and run the benchmarks again, and then do so a third time.
Compare your results. They should be very close, indicating you have a reliable measurement. If you have moved your mouse or bumped the system while a test is running, it can falsify the results of that test. Open wpcrset. Click the "ADD" button. Do not make any entries in the left hand three boxes. Their values should be "0", "0", and "0" for Bus, Device, and function. We are modifying the Host to PCI bridge, which is represented by these values.
In the right hand two boxes, enter 52 in the register box and E0 in the data box. Record the information on your notes. Click the "OK" button and click the main application "OK" button to exit wpcrset. When you do this, the application will ask if you want to reboot your system now, and you should choose to reboot.
When your system has rebooted, go directly to Sandra without opening any other programs, and run the Memory Benchmark to see if your change has made a difference in your measurements. If no difference has been made or memory performance is less, restart your system and measure your memory performance again.
If there still is no change or a lesser figure than your baseline, open wpcrset and remove the 52 register entry from the application menu. If you have effected a performance increase, do not delete the entry. At this point, enter the memory benchmark figure you obtained in your notes, and proceed to add another entry in wpcrset. Click the "ADD" button and enter 54 in the register field and 03 in the data field.
Run Sandra again and note your results. At this point, those of you who couldn't wait to try this either have obtained a performance increase, or you haven't, and the more careful of you want to know exactly what this modification does before you are willing to consider doing it. This document contains register descriptions and setting values, which is what the tweaking process modifies. I'd like to digress here for a minute and urge you to download this datasheet.
It is now a Wordpad. The link is no longer posted and downloading large files from Taiwan sites is challenging. This datasheet used to be available in Adobe Acrobat. These documents are getting harder to find as the products become obsolete, so download them now, while they are still available! By reading this document, you will know what Hex address e. The application wpcredit is a good way to see how registers are currently set in M chipsets. Download this application and install it on your system.

This program is available strictly "as-is". This patch will disable the "turbo mode" feature of newer Creative drivers, which will solve "crackling" or distortion problems for some users. Current Version 0. This is a Windows driver that will patch motherboards that have VIA chipsets.
It is intended to solve many problems, including these:. The beta versions have been dangerous to use on some motherboards, especially on older Athlon motherboards with a Creative Labs sound card installed. It only shows those results when I change it in the current Windows enviroment. I made it permanent but when I reboot, I do not get those amazing results.
But I did do some more tweaking and finally do get a consistant result each time I boot, so it looks like these results I am attaching are the most accurate. Wil Bloodworth. Memory interleaving is a way to get your machine to access your memory banks simultaneously, rather than sequentially. This works on all Via-based machines as well as many other chipsets, though the Via chipset shows the most benefit. Until now, Via boards have always lagged behind the BX boards in memory performance.
This tweak goes a long way towards redressing the balance. BX owners should also check to see if their interleaving is maximized.
To check whether your system has interleaving, or enable it, you will need to download a small app. H-Oda, the person who has written a number of great utilities, including SoftFSB, has compiled a couple of neat apps which allow you to make changes to the PCI register Note: This is not the Windows Registry so you can make and test all sorts of memory tweaks.
If you are familiar with hex editors, this will not look strange to you. If you make a mistake, all settings will be returned to normal on the next boot. As you can see from the picture, you will see the main window is a grid of numbers. These show you where the particular bits of code are; they are called offsets. To find an offset, you look at the first digit in the left column to find the first digit, and you look at the last digit in the top column to find the last digit.
Where those two meet is offset If you wanted to edit offset 51, you would move your cursor to that location. You will see information show up at the bottom of the screen. The box in the bottom left corner shows which offset is selected for editing and what the current value is. The information in the center bottom breaks down the current value by hex and bin number.
You will see a yellow star appear next to the options in the right hand window.
