CAS2 or 3
« on: March 07, 2001, 10:15:00 AM »
OK, I have 256MB of Micron's 133PC ECC CAS3 memory. There was no CAS2 PC133 when I'd bought mine that's why it's ECC, cuz I thought it would be somewhat better (it was marginally more expensive).

Would I see any difference with CAS2 type?

Check here for good information.

edit: only 10 billionths of a second between the two types.

CAS 2 memory is of better quality.  On a good MB you can set timings more aggressively and get a quite large performance gain.  The CAS difference itself isn't really the main performance difference.  Mainly you want to look at the memory speed.  (7.5 ns is pc 133 etc.)  The lower this number is, the better.

I currently have my memory overclocked from the 133 Mhz fsb to about 138.  This gives a significant gain and cheap memory wouldn't be able to do this.  (Side effect of my Tbird running at 927 Mhz.)

(BTW:  ECC memory is slower than regular memory with ECC turned on.  It is actually used mainly for servers where reliability is critical.)
