Ok, sorry for the barrage of G5 related questions, and since no one has one I appreciate anything anyone has to say <br><br>I've read that RAM with lower CAS ratings is faster than those of the same type with higher CAS ratings. Presently you can buy DDR SDRAM for the G5 with 2.0, 2.5, and 3.0 CAS ratings.<br><br>If the price is about the same for all three, then it seems like the best choice would be the one with the CAS rating of 2.0. However, if you have multiple RAM modules on your motherboard it will default to the slowest module. Does anyone know of any information that would tell me what CAS rating the RAM is that Apple ships by default with the G5? Do you think they would tell me if I called them?<br><br>Yes, yes, I know this is probably more work than its even worth, but it helps pass the time waiting for my "baby". <br><br>

Betcha it ships with 3s.<br><br> Alas, poor Yorick. -- Hamlet

Doh!!<br><br>

What's CAS rating?<br><br>

It has to do with the speed of the memory, lower is faster. I don't know what the acronym stands for.<br><br>

I bet Yoyo's right, they probably give you 3. I would call Apple and ask about that. If they do give you slower RAM you could always sell it and buy new faster RAM for cheaper. I don't know the impact 2 has compared to 3 but looking at the G5 i would guess that RAM will be a big part of it' performance, especially if it's taking the place of L3 Cache<br><br>

Yeah, I guess I can run the hardware diagnostic CD to find out?<br><br>I only got 512MB from Apple, so I suppose I could just sell it. I already bought 1GB of CAS 2.0; it wasn't anymore than 2.5 or 3.0. If Apple's RAM really is 3.0 then that is just one more reason not to pay for their RAM. At those prices they should at least be giving you the best RAM possible. Geez!<br><br>

TechTools, at least version 3, has a hardare utility that will tell you what the CAS number is. You can't run it on a G5, though, since it's a Classic app. Version 4 has been about to come out for about a month or so, though.<br><br>edit: That's TechToolsPro, by the way<br><br> Alas, poor Yorick. -- Hamlet<P ID="edit"><FONT SIZE=-1><EM>Edited by yoyo52 on 08/22/03 11:25 PM (server time).</EM></FONT></P>
