Need help translating the StuffPCR settings to WPCREDIT

I need this to enable the hack in w2k

This is borrowed from "bmg" of Australia. I thank him for supplying me with the info and .bin files.

I've got both the memory fix and agp 4x working now using stuffpcr. As has
been noted, changing agp to 4x doesn't work with wcredit or wcrset. Since
stuffpcr is executed from autoexec.bat before windows starts up, it works
ok for setting agp.
Get stuffpcr at:

If you want to make your own .bin file:

Get the Hex Workshop hex editer at: http://www.bpsoft.com
Using the hex editor create a binary file (I called it 815.bin) and input
the following:
50 08 44 73 38 A0 B0 01 80 A8 07 14 A4 07 07
(Note: In Hex Workshop select Options/Preferences and set "Group by" to 8
bit.)
The first 6 bytes do the memory config tweak and the last 9 take care of
agp 4x.

Now, looking at the binary file data I recognize:

Mem hack:
50-44 (what the '08' in between mean I don't know)

AGP4X Hack:
B0-80

I just don't get it....what's all the other numbers doing? I see several promising settings here (after inspecting the numbers in WPCREDIT) but I have a hard time figuring out the grouping of the numbers...i

Found som info myself, from the readme.txt (StuffPCR):

What happens if you want to make a change in the BIOS setup? How about loading
a new BIOS? In both cases, you need to temporarily turn off WPCRSET and resave
any changes you want made in WPCREDIT (remember what you did)? The reason for
this is that WPCRSET overwrites the entire byte offset rather than the subset
you may be interested in modifying.

I wanted something more flexible. Instead of an offset/value pair, I use a
3-byte offset/mask/value. The mask is used to identify which bits in the
register you want to modify.

Where the most interesting part is: 3-byte offset/mask/value

so three number groups is needed for each setting...ie:

Mem hack:
-------
StuffPCR: 50 08 44 73 38 A0
translates to
WPCREDIT: 50-44 and 73-A0
-------

AGP4X hack:
-------
StuffPCR: B0 01 80 A8 07 14 A4 07 07
translates to:
WPCREDIT: B0-80 and A8-14 and A4-07
-------

This is a bit more comprehensive than the standard WPCREDIT settings I see people using here (most use 50-44 and b0-80 it seems)...now the question is, will these additional settings work better and improve performance?

trying it now....

Tried it now, and seems to work fine, except one of the AGP4X fixes which try to turn on Fastwrites, this couse system hang when running games, so I used this instead:

Mem hack:
-------
50-44 ->Works fine for me (Dram bank close policy)
73-A0 ->Works fine for me (Mem write throttle settings)
-------

AGP4X hack:
-------
B0-80 ->Works fine for me (Turns of 4X AGP override)
A8-04 -> changed it from A8-14 to A8-04 to remove the buggy Fastwrites feature, and enable 4X
A4-07 ->Works fine for me (Enables AGP4X)
-------

got somewhat better performance =) and nommore degraded performance when exceeding 140MHz FSB
