overclocking memory

[comradpoplin!]

ok im used to overclocking my cpu & graphics card but with memory i havnt got a clue so i was woundering if you could give me some pointers my memmory is a 1gb stick of elixir ddr400

system-
amd sempron 1.5ghz 2200+ @ 1.93ghz 2800+ @215mhz fsb x 9 multi
msi-kt4av with corcell
3d prophet 9800pro with arctic cooler @ 460mhz core/370mhz memory
120gb seagate barracuda 7200rpm
1gb elixir ddr400 @stock

ok here is what i see in the dram settings page on my bios=

system performance = fast
current host clock =215mhz
configure sdram timing =auto
sdram freaquancy =400mhz
sdram cas latency =auto (default is 3 when set to 2 pc wont boot)
row precharge time =auto
ras pulse width =auto
ras to cas delay =auto
write recovery cycle =1t (i set this to 1t)
bank interleave =auto
sdram burst length =4qw
sdram 1t command =enabled
fast r2r turnaround disabled

i have no idea how to set timings and bits like that so be gentle
voltages are all default what id like to know is, what i should change to get best results and what can really screw the memory up if i do it wrong.
and of course some oppinions on settings you would personally use thnx in advance

You are already overclocking the memory as it is rated for 200Mhz and currently running at 215Mhz.

These are the settings you can change:
system performance = fast
current host clock =215mhz
configure sdram timing =auto (manual)
sdram freaquancy =400mhz (leave it at that i.e. 1:1)
sdram cas latency =auto (2 or 2.5 would be faster but not all RAM can handle that)
row precharge time =auto (2, 3 or 4, 2 is faster but might not work)
ras pulse width =auto (don't know)
ras to cas delay =auto (2, 3 or 4, 2 is faster but might not work)
write recovery cycle =1t (don't know)
bank interleave =auto (enable is faster but might not be stable)
sdram burst length =4qw (don't know)
sdram 1t command =enabled (is fastest already, other option is 2T)
fast r2r turnaround disabled (don't know)
