I figured out the issue with the Perfect Storm sticks. With auto subs, if you set 7-9-7 at 2200, the Asus boards try to set tWCL to 7, which is actually ideal but too tight for most BBSE from what I've read, hence the code 55. If I manually set tWCL to 8 (which is what the Tridents default to) they'll boot just fine.
