I'd like to buy 2x1GB. I don't want Crucial Ballistix

My config:
MSI K8N SLI Platinum (5.06 bios) -> vmem max 3,1 v
A64 3000+ @ max 9x319@max vcore (usually 9x311@1,45vcore)

This 5.06 modded bios (best so far) offers 100, 120, 133, 140, 150, 166, 180, 200 (and 216, 233, 250) memory dividers

According to my A64@OC, mobo and its memory dividers what sholud I choose? GSkill: ZX? HZ? HX? Something else? And why?
