Thean, 350, 400, and now 450MHz systems will have a 100MHz system bus. 333MHz and below will have a 66MHz bus. If you go to Dell's "build your own system" area you'll see that explained in the memory options section. On V.90: You don't have to worry about not being able to connect. If you've got X2 and your ISP has Kflex, or vice versa, all the equipment is "smart" enough to negotiate to the previous V.34 standard. You'll only get a max of 33.6K baud, but you'll connect. If you get a V.90 capable modem (and your phone line is good enough), eventually you'll get something closer to 44K, when your ISP upgrades to V.90. It shouldn't take too much longer. You'll just get the higher data rate right away if your modem matches your ISP's standard. So how did this mess come about, you might ask? US Robotics/3COM was first with 56K baud with their X2 technology. Rockwell et.al. didn't like it and came out with Kflex. Both camps pledged to agree on a standard which they eventually did. V.90 is that standard. It's closer to Kflex technology than X2, but 3COM seems to have gotten their upgrades out faster. All 3COM 56K modems are now compatible with both X2 and V.90 standards. I think most of the ISP's that use 3COM equipment have already upgraded to X2/V.90 too. It may be just my area, but none of the Kflex equipped ISP's I've tried seem to have upgraded to V.90 yet, but they promise they will. It's a pretty safe bet that when they do they'll support both Kflex and V.90. But why does a 56K modem only get me 44K, you might ask? To get the full 56K the ISP's modem has to put an illegally high voltage on the phone line. Until the FCC gets it's act together and updates the rules, the ISP's have to "throttle" their modems to about 44K. Regards...Alski
