LX6 SDRAM settings

[Gwydion]

I just dropped 64MB of Kingston SDRAM (3.3v 10ns) onto my Abit LX6 motherboard; I had 32MB of Micron SDRAM (3.3v 10ns) already on there. When I went into BIOS to check the RAM settings I noticed that the default was 50 or 60ns. I assumed that since SDRAM works with the processor, I did not need to worry about the ram settings. Unfortunatly when I ran Sandra Soft and Dr.Hardware I found that my RAM was running at either 50ns or 60ns, depending on what default I set it at. I thought I knew a bit about RAM, but the custom settings absolutely baffle me, if you know what custom settings are ideal I appreciate any help
