me personally ive owned 2 of each[raid/non raid] all of which have given me lots of problems,
i was having lockups galore and so i had the VERY EXPENSIVE task of trying to figure it out. so i started with buying a new AGP,then HDD,power supply,RAM,removing the pci cards,flash the bios,FAQ's only give ideas but i never did fix it.
so i returned it and got a replacement,same thing.
bought a non raid ,same probs.my whole system was replaced piece by piece! i swapped parts from friends pc's no success.
then i was building a system for my friend and i wanted to try the MSI limited ed.... and they were out of stock so i had to try another [thinking it was just me that has bad luck!] and off i went again and the same crap over again ,had to take it back and they gave me 2 others b4 i had to scream at them as they had the msi instock but listed it as "pre order" and were too lazy to update their website! so i eventually got the msi and guess what? no more lock ups and no more stabilty problems.
even though i use IWILL myself ,i still think the MSI is a great motherboard!
