Your ram, if its good, will support 2 easily...
Reduce to 2.5 or 3 if the ram is really naff...

(i guess a speed increase of 6 - 10% might be possible)

But your motherboard/Bios might not support Cas rating (it will be preset on `Auto`)

Have a read of `BIOS for Beginners` here.
(no mention of CAS there though)

Might check my BIOS in a little while.


Don't bother messing around with your CAS settings, unless you paid top dollar for your RAM... the SPD of the DIMM will automagically set the right setting. if you get it wrong you'll have to clear the CMOS which is never a fun thing to do.

Hum,
are you sure?
You can just enter the bios again and set it to a a slower speed (at worst you may have to reset it back to `default` or `super-duper-turbo-mode`)

On some systems, yes.  I had to do it on mine.

Sure.  You can reset it from the BIOS.  But, if the RAM CAS is too far past where the system is stable, it may not stay up long enough to change back.  (The system needs to be running to get to BIOS.  ;-) )

Also noteworthy:  A small change on bus speed, plus a small change on CAS speed can equal a HUGE change on the effective speed of your RAM, causing you to OC it to a point the system won't boot.  Not that I did that and had to clear my CMOS...  Nope.... (whistles innocently)

Jup... made the mistake many years ago of setting some CAS 3.0 RAM to 2.0... system couldn't even get to the BIOS :-(

What nightmare of windows?

Got the ram this morning and just installed it now.  No problems, but it took windows slightly longer to start up...

--edit--
Ok, after shutting down to put the cover back on and put the pc back on the desk I restarted and it went just as quick as it used to.
