As the advice from Macci,(run 3d mark 2001se, game 3 high details only);please see here
Mobo: MSI k8n neo2 Bios: 1.3b6
RAM: 1.Mushkin PC 3500 Level II BH-5, 2x 256mb DC kit
2.GSkill TCCD DDR550 2.5-3-3-7, 2x256mb DC kit
OS: Windows 2000 SP4
CPU AMD s939 3500+ 90nm
Power: OCZ power stream 520W
HD: Maxtor 6E040L0 IDE

Let's see those two set of RAM:



1. BH-5 273x11 2-2-2-5:



2.TCCD 300x10; 2.5-3-3-6:



It shows that results are really close to each other.
Therefore, I think there is no need to do BH-5 at 12x250, 2-2-2-5 right?

Thank you everyone.
