I am testing out a bunch of RAM that I have. I have been doing bandwidth tests in Sandra to see how well it's working.

I am including a list of what I have and how many of each I have as well as the bandwidth results for for the tests I have ran.

1x Centon PC3500 512Mb CL2.5 (Runs at PC3200)
1x Simpletech PC3200 256Mb CL2.5
3x Ultra PC3200 512Mb CL3

Tests:
Bios is set to automatically detect all RAM timings, I am including the CL reported by the bios after the bandwidth number.

1x Centon 2595Mb/s CL3
1x Simpletech 2612Mb/s CL3
1x Ultra 2575Mb/s CL3
1x Centon + 1x Simpletech 2454Mb/s CL3
2x Ultra 2561Mb/s CL3
3x Ultra 1194Mb/s CL2.5

I know the Ultra RAM is only CL3 but for some reason the Bios registers it at 2.5 when it boots with all three installed, why would this be. If I manually change the CL to 3 in the Bios, I get 1197Mb/s bandwidth when I retest. so evidently that doesn't seem to change anything ultimately.

Why would it fall so much when 3 of them are installed?
