As per Apple notes - more than just meeting JEDEC specifications, modules going into Mac Pros need to have the appropriate heat spreader. Use of JEDEC standard modules without an Apple Qualified Heat-Spreader can result in higher fan speed operation or even a slow down of the installed memory in order to prevent overheating. We also have seen it reported that some who have used non-Apple qualified modules have experienced 'Soft Errors' ECC reported. - do you think this is legit ?
