• Abit TH7II is a great mother board which supports with  socket 478 processor and Rambus memory.
• Two problems with this. 1. Rambus memory is out dated to be replaced by DDR memory and 2. Front bus access is 400 mhz and does not include 533 mhz. So Basically this board is out of reconning because of these two reasons.
• Price for ABit TH7II is $167 at square

• The difference between a 2.4 pentium 4 for 400 mhz and 2.4 ghz Pentium 4 for 533 mhz front end bus. The 2.4 pentium 4 for 400 mhz front end bus is called A and the 2.4 pentium 4 for 533 mhz is called B.
• ABIT---IT7—This MOBO does not support any legacy systems ps2 connectors for key boards etc not serial or parallel ports for printers.
• It has USB2.0 and FIREWIRE 1394a respectively
• It has the First mobo with intel I845E chipset . This officially support for 533 FSB(133 FSB QDR) for upcoming northwood B P4s.
• The south bridge I/O controller hub is ICH4 which provides connection for 6 USB2.0 Other features are ATA100 support integrated LAN interface, AC97 audio and modem capabilities. Most feature laden MOBO to date.
• THE SPECS :  P4  supports upto 2400 MHZ and more, Memory –2GB RAM DDR200 RAM.

AGP slot and 4X32 Bit PCI 33 mhz slots.The socket has an etching to take the largest coolers. Alpha PAL 8942 T. RAID 0,1 and 0+1 gives great ide management and flexibility. Has full duplex AC’97

• Great Stability on test benches.

MOBOs with 845 chipset for DDR

• The 850 chipset can from Intel requires RDRAM which is expensive and also on the way out.
• The 845 E and  845 G are the only chipsets that support DDR and also 400 mhz and 533 Fsb’s
• At the least a mobo should support PC2100 DDR Memory.
