Thanks to overclockers.com, I started playing with WPCREDIT on my MSI K7T Pro2A motherboard.
Before tweaking, my Sandra memory score was 402/492 for PC133 CAS2.
Here's a list of offsets and what to set them to:
These settings require double-sided DIMMs.
Bank 0/1 corresponds to DIMM slot 1. (Offset 64)
Bank 2/3 corresponds to DIMM slot 2. (Offset 65)
Bank 4/5 corresponds to DIMM slot 3. (Offset 66)
Bank 6/7 corresponds to DIMM slot 4 (if it exists) (Offset 67)
Here are Hex and Bin values for any of these offsets:
CAS 2-2-2-5 with 4-way Interleave (BEST setting).
Hex 12 or Bin 00010010.
CAS 2-2-2-5 w/ 2-way Interleave:
Hex 11 or Bin 00010001.
CAS 3-2-2-5 w/ 4-way:
Hex 22 or Bin 00100010.
CAS 3-2-2-5 w/ 2-way:
Hex 21 or Bin 00100001.
CAS 2-2-2-6 4-way:
Hex 52 or Bin 01010010.
CAS 2-2-2-6 2-way:
Hex 51 or Bin 01010001.
CAS 3-2-2-6 4-way:
Hex 62 or Bin 01100010.
3-2-2-6 2-way:
Hex 61 or Bin 01100001.
To disable interleave, change the last two Bin digits to 00.
By setting my memory to 2-2-2-5 4-way, my RAM scores went from 402/492 to 455/553.
Hope this helps some people.
