I'm going to be maxing out my RAM pretty soon. I noticed when browsing online that some RAM has lower latency than others (eg CL2 vs CL3) and I have read that this can give the user 'noticeable benefits'.
I have left a ticket at plugorama but no-one has replied - been 6 days now. Is CAS latency anything I should be particularly concerned about, or should I just go ahead and buy from dabs/crucial. lower latency RAM is more expensive it seems so I'd prefer to buy CL3 if it's not going to make any difference.
Thanks

Don't know weather you're still interested, but CL3 seems to be good enough: http://en.wikipedia.org/wiki/CAS_latency

Sorry we didn't reply to your help desk ticket. Faster RAM costs more but can't hurt anything. All Receptors now come with 2GB of RAM, the standard blue front Receptors use CL3 RAM, the Receptor PRO uses performance matched CL2.5 RAM. We do not see any discernible difference between CL2 and CL2.5 RAM, but you can use CL2 RAM if you don't mind spending the extra expense...
Even more important is the RAM speed. Since I'm pretty sure we've never shipped any Rev C units without the full capacity of RAM, that would mean that you have a Rev A or Rev B Receptor. You should use at least PC2700 (DDR333) RAM clock speed, or better yet, purchase PC3200 (DDR400) speed RAM if you want to upgrade to a Rev C at some point in the future.
As always, PLEASE (please please please please please!) only use HIGH QUALITY, lifetime warranted RAM. The main reason we started shipping Receptors with the full 2Gb complement of RAM is that people were blowing up their Receptors (at worse), or making them unstable (at best), by using low quality "OEM" RAM that had shorts, or non-jedec specifications so they didn't fit properly, or were improperly inserted.
In RAM, the more expensive RAM is (usually) the better RAM, and try to get RAM with a heat spreader on it from a reputable supplier. RAM is like oil to your car's engine... you don't want to use crummy off-brand recycled oil in your high-compression turbo-charged engine, right? At least not if you care about getting around without breaking down!

My (new) Rev C came with only 256MB RAM. I settled for Kingston RAM with latency of CL3.groovology wrote:Since I'm pretty sure we've never shipped any Rev C units without the full capacity of RAM, that would mean that you have a Rev A or Rev B Receptor.
