Are there noticable differences from these? PC100/133 and CAS2/3

[LoStZ]

Yes though most say CAS2 is faster than CAS3. I've also read most of the posts through the search. But my question is that is it noticeable? Or would running 512mb of ram at 100 be much of a decrease from 133 for instance? Now benchmark results, etc is not considered. Just when we talk about usage. So would I notice any difference if I were to run my 512mb at PC100 as compared to PC133? Or what about running it at cas3 instead of cas2? Any input is appreciated.

The difference between PC100 and PC133 RAM in pretty significant.....33% increase in speed to be exact. The difference between CAS2 and CAS3 RAM isn't noticeable except when you benchmark. Most people say CAS2 is only about 3-5% faster than CAS3.

Thanks for the reply. Also, which would you prefer, running CPU at 750mhz and memory at 133 or running CPU at 810mhz and memory at 100? Would the 133 over 100 memory speed outweigh the few mhz decrease? Please let me know, thanks.

yes i think its obvious 100 to 133 is a 33% increase...he is wondering if its noticeable in general usage of the computer. I would say that if you paid real close attention, and maybe were using memory bandwidth hungry apps, you would notice. it depends on how picky you are.

go for 730/133.

750 to 810 you will barely notice if at all. (i doubt you will notice)

100 to 133 you quite possibly might notice.

Thanks shooters and mackstann for the input. I have 2 256mb PC133 Mushkin Basics. Do you think these would run cas2 stable? Or should I not bother, since the increase isn't even notable? Again, thank you.

Try to shoot for the highest CPU Mhz you can wring out of the CPU at the same time the highest FSB. If it's not feasible, compromise on the CPU Mhz before the FSB. For example,my Athlon900 will oc either to 9X120FSB=1080 or 8X133FSB=1064. These are the highest stable Mhz I can wring out of this CPU. So the better choice of course is the 133FSB. Because it speeds memory! Although the 120FSB may just be a little off 133 and at the same time is higher in CPU Mhz, it also overclock the rest of the components, i.e. AGP,& PCI. But in the long run the lower CPU mhz/133 FSB combo will do better overall system performance.
