Been trying to get my 5x 280x's to work for hours. Need some help.  My bat file is as follows:
@echo off
setx GPU_MAX_ALLOC_PERCENT 100

NsGpuCNMiner.exe -u

-p x
The pools are in pools.txt
When starting I get:  Error  Frontend phase failed compilation.  Error:  Compliation from LLVMIR binary to IL text failed!
I then hit the ok button then I get a bunch of these.  Any ideas?

Updated drivers to 13.12
I have also set the custom size on the pagefile to Minimum: 19000 (~19gb) and Maximum 20000 (~20gb)
