Let me tell you that I have both boards with the same components installed on both boards including OCZ's pc3000 ram ddr that is supposed to easily hit 166 bus on a 266 board, well my abit kr7a raid with the pc3000 ram (copperclad) was an extra 5 bucks but worth the extra cooling properties) ran at 154 MHz at cas 2 on my abit board and it could only run at 133 bus cas 2.5 and i had to slow down some of the setings on my Iwill xp333 ram settings. The xp333 didnt want here about cas 2 it wouldnt even post with supossdly one of the best ddr ram modules out!
Go with Abit or asus if you want to overclock and still go with the latter if you want a system that will go right together without a hitch. It took me three days and many, many ,many reboots to a no post on xp333 its a sucky board if you ask me. I saw a website I forgot where, but this guy was praising the xp333 by Iwill, he said he had pc2400 ram running at 166 mhz ! I find that very hard to belive , especially when i couldnt get copper clad OCZ pc3000 ram to do 137 fsb on that board. Also his was a revision 2.0 that a lot of people complained about , because Iwill reused some left over kt266 board and just put a sticker over the silkscreened kt266 tag with a a label that said xp333...the kr7a raid hit 154 at cas2 on my abit kt7a raid so you decide. Do you want to mess around for days, where you want to take an ax to the board , or do you want a board that will work first time every time?
Hee is configuration on the iwill:
abit geforce 3 TI200 video card, 21 inch monitor, ocz pc3000 ram 256 megs copper clad, ibm 60 7200 ata 100 hdrive,iwill revision2.1 xp333 no raid, audigy sound card which was takin out becuase of too many conflicts so I opted for the omnboard 5,1 hardware sound which sounded very good with my cambridge 4,1 speaker setup, plextor 16x burner , liteon dvd, rounded ide cables all around, 3 case fans in a OCZ Titanium 900, Aluminum Case/enermax 360 watt wisper cool dual fan PS with speed dial on second fan,xp1600+ cpu, tornado cooler, intel 10/100 nic, windows 98/2k dual boot.
