What are these programs? And where can I get them?

The programs we are going to look at are called WPCREDIT and WPCRSET. They are great programs written by the amazing H-Oda. Some of you are probably familiar with his work, he wrote WCPUID among other things. Now these aren’t new programs, but they are highly underused. Mainly because they can be rather hard to understand and even harder to find the proper PCR files. It's rather hard to find the documentation needed to properly write these files. AMD and Intel are both great about posting these for public download but guys like VIA, SIS and ALI all require you to know somebody on the inside to get a hold of what you need. With guys like VIA I believe this is most likely due to how small the variances between releases are.

The first of these programs, WCPREDIT, is used to try out new settings in Windows and see what immediate effect they have; this is great because you can try different memory settings without having to keep going to the BIOS or when your BIOS may not allow you to change these settings. Now what you have to realize is that some settings might not work, or may cause your machine to lock up. This is no problem; simply reboot and all will return to normal again.

The other program, WCPRSET, is used to apply the settings that you find to work when Windows starts. You will need to download the following files: wpcre12a.exe, wpcrs120.exe and AMD762.PCR

Before we go any further, you will need to read this article of mine HERE. That will explain alot of DDR timings to you.

Before you begin you'll need a few files:

·        WPCREDIT

·        WPCRSET

·        AMD 762 PCR File

Once downloaded you need to run both of the exe files, These will then extract all the files needed to continue. Now if you run WCPREDIT.EXE you will be presented with a screen that looks something like the following:

What we see in the picture above is a layout of all the registers that we will be dealing with. The registers all have locations that are determined by Hex values starting at 00 and going up to FF. If you look down the left side you will see 00-F0........... now if you wish to find say register 66 for example you would read down to 60 on the left, the go along until your in the column 06 at the top, just add the numbers together to find the location.
