Intel 925XE Express Chipset -
When choosing a FSB speed for the CPU you choose, be aware that you'll need to purchase memory capable of this faster speed. For example, many people are enticed by the remarkably low priced memory, yet you need to sync your memory to your CPU's FSB. First of all, all mainboard these days use either DDR or DDR2 memory, today's product needs DDR2 memory. In our case we know that the CPU we have uses the 1066 MHz bus so we're gonna need DDR memory rated PC4200, thus 533 MHz DDR2 memory that is capable handling that high FSB. You can also equip this mainboard with a 800 MHz FSB processor, in that case you'll need DDR2 400 MHz. Just devide the CPU FSB by 2 and you are set to go.
Secondly, make sure you buy two bars so that you can have a 'dual-channel' memory configuration, which effectively double's the memory bandwith and the Pentium 4 loves that bandwidth for sure.

Here are some of the architectural highlights for the Intel Pentium 4 Extreme Edition:
Let's take a quick look at the processor and note the bigger differences between this and your 'normal' Pentium 4. The Extreme Edition biggest advantage over the 'normal' 130nm (Northwood) Pentium 4's is the inclusion of 2MB of Level 3 cache, this cache will speed up software/applications big-time, it's also extremely expensive the implement. In addition to the bigger cache, the big difference of course is the new faster FSB speed for the 3.46GHz P4 Extreme Edition.

Intel NetBurst Micro architecture
|Cache||512K L2, 2MB L3|
|Clock Speed||3.46 GHz|
|FSB||1066MHz (266MHz quad pumped)|
Today we are looking at Intel's D925XECV2 mainboard equipped with the seriously breathtaking yet unfortunately rather expensive 3.46GHz Pentium 4 Extreme Edition to try out for a couple of weeks. But let's focus on that mainboard versus chipset. Key primary feature you need to keep in mind is that this mainboard is capable of a lovely 1066 MHz system bus. Your average Pentium 4 mainboard these days run on the quad pumped 800 MHz front side bus, this one can handle a bit more (266 MHzx 4), yes 1066 MHz.
