Please Follow this Guide to make sure your E Slim is RGH Able.
You can remove the top vent and look in through the side at the XCGPU to see if it has the Metal IHS on top of the XCGPU. If it does not have the IHS then it is a Winchester therefor not rghable. if it DOES have the IHS, It's a corona and you are welcome to send it in to get RGHed!
If it is RGH Able then you Can Continue, If not i would recommend to buy one that is RGH Able or buy one from us HERE
