I've heard good things about the SiS chipset. What's a good motherboard that uses that one?
I am particularly interested in FUGGER, AMD_Man, Fatburger, and maybe Raystonn's opinions, as they've all been bouncing these subjects back and forth for a good while, now.
I know people have been discussing RAM and motherboards for the P4 for a while now. Back when the P4 was just launched in 2000, your options were extremely limited but now, you probably have a wider array of options than you do with AMD mobo selection. You have a wide number of decent chipsets. However, there is no one best combo that I would recommend to everyone. I myself have tried the Abit TH7II-RAID and the Abit IT7 and both seem to be fabulous motherboards. At the moment PC1066 is the fastest RAM but it carries a heavy premium price that you'll have to pay. DDR333 and PC800 roughly match each other in performance depending on the app. Good quality PC800 still costs a bit more than good quality DDR333. Most motherboards with Intel chipsets have the ability to lock the PCI/AGP bus so you can overclock them higher. The SiS 645DX is a great chipset but it lacks the ability to lock the PCI/AGP bus above 133MHz. However, the SiS 645DX is the fastest DDR chipset because it can be paired with DDR400 without overclocking. DDR400 is slightly faster than PC800 and slightly slower than PC1066. The only board that has the SiS 645DX chipset and allows DDR400 that I know of is the P4S533. A great reasonably priced combo running at stock speed would be an Asus P4S533 with Samsung, KingMax or Corsair PC3200 (DDR400) RAM. As for stability, I wouldn't think too much about it. As long as you avoid VIA on an Intel platform, you're fine.
That takes me to another point:
Some people prefer to have an all Intel system; that is, an Intel processor with an Intel motherboard or at least an Intel based motherboard. If that's the case, and you still can't see yourself spending extra for PC800 or even more for PC1066, get an IT7 (if you don't care about legacy support; the IT7 is all USB and Firewire), or BD7II (if you still need legacy support, such as a parallel port, serial ports, PS/2 ports). However, if you have loads of cash and want the best of the best, I'd wait for the P4T533 and RIMM4200 RAM. RIMM4200 is a new standard of RDRAM. PC1066 is just as fast as RIMM4200 but it has to be installed in pairs. If you just want to go with PC1066 then get the P4T533-C. I wouldn't recommend the Gigabyte GA-8IHXP because the price is simply too inflated at the moment. Sure it has extra features but it's priced $100US higher than the other boards for no good reason, in my opinon. I'm sure they'll drop the price a bit in a while.
Well, I hope this helps.
