Today I decided to tinker with the memory settings on my P3V4X too see if I could help my Sandra benchmark scores anyway, and I noticed something interesting the scores. I'm using a 128MB stick of Kingston PC100@133. The BIOS on my board is revision 1005.
Speed set in BIOS as "BY SPD" = Sandra score 248/296
Speed set as 3-3-3-6 = 219/242
Hmmm, why the difference? Even on the first setting, the speeds are set 3-3-3-6. I found out why -- when using the "BY SPD" setting, the BIOS enables 4X interleaving. If the speeds are set manually, only 2X interleaving is enabled.
Anybody seen this before? Or do I have a wierd one?
If anyone is curious, using H-Oda's WPCREDIT, I did some more tweaking and found the following:
2-3-3-6 2X interleave = 226/259
2-2-2-5 2X interleave = no post (rats!)
2-2-3-6 2X interleave = no post
2-3-2-6 2x interleave = 241/280
2-3-2-5 2x interleave = 244/279
2-3-2-5 with 4X interleaving enabled = 270/330
This is pretty much as fast as my ram will go. O well, with 4X interleaving this Via chipset doesn't look too bad! (The Athlons/Durons/Tbirds will always beat it, but it's not far from the good ole' BX.)
