Yes, best to use auto. The bios should read the ram chip specs
from the spd on the dimm and set the ram timing appropriately.

The main use of the manual settings is to deliberately overclock the ram,
run it at faster timing specs than the manufacturer's specs guarantee.

They are basically ram timing parameters. There is no easy
way to explain them in a sentence or two, that area is very
complex and an explanation wont help you any anyway.

Thanks Rod.  I have another quesiton, now, though: none of my other chips
gave me that message when booting up, only this new one.  The BIOS was
configured to run at 3T, not the 2T of this new 128mb chip.  Could this
indicate something about the new ram in the areas of quality or speed?  I
bought a 64mb card of LD ram a few weeks ago, and it did not give me this
message, only this 128mb new LD card, so I'm wondering if I got the same
quality (A-Grade) or if perhaps the card I got was from the wrong box?

TIA,

Ari

How dare you ?  Whatever gave you the idea you can ask those here ?  |-)

OK. Basically the bios has read the spd on the new 128MB dimm,
noticed that the specs for the ram chips specified in the spd allows
the CAS to be 2T and its just telling you that the new dimm can be
run at 2T, not the 3T that you have the CAS setting set to.

If you had had it set to AUTO, it likely would have just used 2T
without bothering to say anything when you changed dimms.

Yes, that the new dimm can do a CAS of 2T. It works that out from the
spd on the dimm that contains the specs of the ram chips on the dimm.

Because the spd on the 64MB dimm said it needs a CAS of 3T.
You had it set to 3T, so the bios made no comment at boot time.

Dimms are available which can do CAS 2T and 3T.
The 2T capable dimms have better/faster ram chips on them.

Nar, both speeds are available.
