I have a 256Mb ram PC2100 module set at the standard 266MHz.
I want to add another 512Mb, but I'd like to buy a PC2700 module, and set it, of course, at 266MHz.
Are there any problems to put them together?
I have a MSI mobo based on the Sis745 chipset, which supports PC2700, but not the 333MHz FSB.
They cost the same, and in some places, PC2700 is cheaper than PC2100, at least here where I live (Italy).
So, I don't want to but a PC2100 module that, maybe, it will give me problems running at cas2 and all the other fastest timings (the PC2100 module that I have installed works great, but I consider myself lucky on that one)
Your memory is only as fast as your slowest module, this means that if your slowest module runs at a frequency of 266Mhz and times at 3-3-3-6 then even if you buy a high quality module to add to your board it will only run at the speed of the slower module, there is no way currently to indivdualy clock or time independant modules seperately, probably because that would cause instability.
With that in mind, since you plan on using your old module with your new one, make sure that the frequency and timings on your new module are atleast as good or *Better then the one you have, you dont want to get even slower timings and lose performance.
I would suggest buying pc3200 that way when you replace your mobo in the future you wont have to buy new ram for the board unless you just happen to want more memory, or plan to run in dual channel mode.
I hope i have helped.
