//No. ram_check() is a useless metric.

OK, I get it. Thanks.
Memtest86 reports errors at memory address
1MB, 5MB, 9MB, 13MB, 17MB, ... not sure what's wrong.

yes, I used corey's cn700 patch, and after changed some values I can run
ram_check successfully,
but as you have said, it's not quite useful...
corey's original patch couldn't pass ram_check, and I have no idea why.
