I bought some RAM from Corsair a week and a half ago and when I installed it it was clocked at 1333, when it was sold as 1600.

in the system BIOS when I changed it to 1600 from auto it caused issues and required resetting the BIOS. I managed to fix that issue, but my question is why? Is it bad? Did Corsair send us under clocked RAM? Is there something I could do to fix it in the BIOS that will not mess the system up?

It's the same for all RAMs. They advertise the XMP settings, not the default ones (SPD).
Try setting in BIOS the AI Overclock Tuner to XMP.

I tried setting the BIOS setting from auto to 1600. It caused the machine to be unstable. It would not even boot to BIOS. IT would start to power up then power down before even getting into BIOS.

What happens if you enable the XMP?

To 1600? The memory timing should look something like this: 9-9-9-18. It should be printed on the side of the Ram module. You should set the bios timeing to those numbers unless you are overclocking. Then verify that your motherboard and that specific Ram are compatible. Should be in the MB users manual.
