ROFLMAO one word bro - NOOB. Some people should just stay away from computers
If your buying ASUS or Gigabyte, with Intel chipsets for Intel based systems you should have no issues or no wide spread issues, if you buy rubbish like ECS, Elitegroup, PCChips, MSI etc then expect things like that.
ECS is Elitegroup and PCchip is OWNED by Elitegroup. Also my ECS K7S5A was seriously the BEST board i ever bought.....Worked with any ram i tried it with ran any pci card i placed it in. It was also extremely stable...
Years later i got my Asus K8V SE.... certain PCI cards did not work. and the audio randomly skipped. Turned out that a bios update to fix one problem made several others.... a roll back did fix it...
My P5W DH did not overclock well....early revision.....What i did like was that all fans could be controlled. It was quiet. Dual lan a fair amount of sata ports and driverless raid(a silicon image chip handled this)
Gigabyte P35 DS3r. Has exactly the features i want and was a good price....
So in the end you DO get what you pay for(even if its features you never use)....
The ram issue is not a board problem, but a problem of with the way SPD timings are written on the chip. To avoid problems most manufacturers set lower timings since most new ram needs more voltage to get its spec'd timings. This allows you to manually set it. Tight timings caused many problems in the past where the board would say....ohh 800 @ 4,4,4,12 then not post because it was only giving the 1.8 volts from the JEDIC specs as opposed to the 2.1 the ram wants.
For the IDE thing. Some boards have IDE controllers that only support ATA and not ATAPI(Jmicron ones should see CD/DVD's fine....so it its one of those not working...RMA it). That would stop a CD drive from working. Solution, use SATA
To make raid work you have to set it in the bios, then enter the raid setup on the next boot(CTRL + I). If it does not work like that, RMA
