Set Memory Timings in BIOS

[bloodandsoil]

I have Crucial Ballistix PC2-6400 memory with timings of 4-4-4-12 and I have no idea where to put them in my BIOS.

In my BIOS (Asus P5B-Deluxe motherboard), when I switch SPD from Auto to Manual, here are the values presented:

DRAM CAS# Latency = 5
DRAM RAS# to CAS# Delay = 6 DRAM Clocks
DRAM RAS# Precharge = 6 DRAM Clocks
DRAM RAS# Activate to Precharge = 15 DRAM Clocks
DRAM Write Recovery Time = 6 DRAM Clocks
DRAM TRFC = 42 DRAM Clocks
DRAM TRRD = 10
Rank Write to Read Delay = 10
Read to Precharge Delay = 11
Write to Precharge Delay = 10

Thanks.

Change the first four items in the list (those marked with a #) from 5-6-6-15 to 4-4-4-12 :?

Thanks for the reply 31.
I've been attempting to puzzle this out too.

What do I do with the remaining 6 options?

I've seen people recommending multiple different settings for these 6 options. I have no idea what to do.

Neither have I :? Leave them alone if you don't know what you are doing. (see my message below!)

true & in general I agree- if it aint broke don't fix it
but...
there is a point to trying & optimizing ones system. I mean, that's why we build instead of buy from dell right?
