Ram Question Corsair Value Select 2x 512mb DDR 400

Im a little confused on timings. My ASUS P4c-800 timings have settings for 5
settings. I am trying to use settings of 2.5-3-3-8, but there is another
setting after the 8, that I am not sure what to do with. Help!

The setting is the DBL or DRAM Burst Length. This option basically
controls the amount of data that can be "burst" in one read/write. A
"burst" has the advantages of only needing to invoke the CAS latency
one time, allowing for less delay than a "non-burst" transaction.
However, "burst" transactions can only be used for contiguous blocks
of data (as only one column address is sent in the burst). Bursting
feature is a technique that DRAM itself predicts the address
of the next memory location to be accessed after the first address is
accessed. To use the feature, you need to define the burst length,
which is the actual length of burst plus the starting address and
allows internal address counter to properly generate the next memory
location. The bigger the size, the faster the DRAM performance.
Available settings: 4, 8.There is no advantage to changing this value
according to all reviews I have read though theoretically your ram
should work some small percentage faster using the 8 setting.

Thanks for this excellent and well documented response. I had the same
question since a lot of time, but never got a good explanation.
