On the Chaintech website, there is only one CT-7AJA2 - this one is a CT-7AJA2E. If these are indeed 7AJA2 with the KT133A chipset, there is a BIOS upgrade to take a XP2000. For $33.50 (don't forget the 10% too) it would be a great deal!
Also, there are Vcore adjustments and 1Mhz clock speed adjustments.
