No problems to report yet, working well, I wish I had multiple x4 or x16 slots and use those instead of x1 cards (the mobo would need to support the I/O as well).. > > Doesn't that HighPoint 23xx card also use the Marvell 88SX7042 chip?

That's a good question, I suppose if it was easy it would have already been done?
