100mhz 128MB SDRAM or 133Mhz 64mb SDRAM?

[RickyOyola]

Im not sure which one to use 100mhz 128MB SDRAM or 133Mhz 64mb SDRAM?
Thanks

Well if you can't use both then use the 128 of 100 mhz. If things are that desperate then the extra ram will be worth a lot more than the 33 mhz.

It depends completely on the system. You cannot just compare RAM speeds and draw a conclusion. If your system bus runs at 133 MHz, then any amount of 100-MHz RAM will slow things down. And if your system bus runs at 100 MHz, it won't run on certain high density 133-MHz RAM.

yeah my system bus runs at 133

If you had 64mb of 133 it would be slower than 128 of 100. With 64mbs, the computer would spend so much time going back to the hard drive it wouldn't mater it is 33 mhz faster.

I'd use both also ,if you can.

you should be able to use both, the 133Mhz ram will just throttle back to 100Mhz and you'll have 192Mb 100Mhz ram in total.

yeah but i also have a 256mb 133mhz ram in and i only have 2 slots

That might be less of a clear choice. If your system is using more than 320mbs@133 running a program, I would think 384mbs @100 would be faster IF your system is not using more than 384mbs. If your system has to go to the hard drive things slow down more than a 33 mhz loss in the FSB
