cas question k8v

I've just put together my first home built. I have 1 GB of Corsair Twin XMS
pc3200 DDR400 in two matching 512 modules. In BIOS the cas latency is set
to Auto, with options of 2.0, 2.5, and 3.0. What should I be running this
ram at? I think the cas numbers from newegg were
2-3-2-6.

Thx...

btw rest of box is:

120GB SATA
Radeon 9800XT 256MB
Athlon 64 3400
XP Pro

If that matters.

THANKS

Thx, Paul. I did check out that .pdf, and it said "tested at advanced
latency settings."

Still not sure what I should run it at...2, 2.5, or Auto. It says the
latency is 2-3-2-6 for my modules.

Thanks for your help.

I presume the first digit on the string is CAS Latency, so setting
CAS to 2 or using the Auto function should work. (I tried looking on
the Corsair site, but all their "tech docs" are a load of hot air.)
Have you checked the forums of Abxzone, to see if there are any
gotchas, in terms of setting up the BIOS, or using certain
settings ? Sometimes, a brand new board will have BIOS bugs (in
extreme cases, the BIOS even ignores the SPD EEPROM or doesn't
actually use the memory timing settings entered by the user).
I wouldn't want to steer you wrong, without checking first what
other users are experiencing.

For example, here is a thread where a memory problem was solved
by increasing the voltage to the DIMM:

This thread has some sample timings being used.

Normally, the worst that should happen, is maybe you might need
to clear the CMOS to recover from a bad RAM setting. A good BIOS
should detect that the computer crashed since the last POST, and
reset the settings to a safe default. If you do need to clear
the CMOS at some point, read the procedure carefully in the manual,
as, for example, you can damage some motherboards unless the power
plug is pulled from the wall, before clearing the CMOS.

Have fun,
Paul
