There is a Gold Pin related to RAM slot missing at the back side of the board. The soldering is clearly visible on the board where the Gold Pin is suppose to be there also I checked with the seller posted photos of his motherboard. Gold PIN is there in the pictures clearly. Seller says it wont effect much if the PIN is not there, where as similar kind of Gold PINs are there on the Motherboard. I did check with my original not working board it is there. I will return back the product and please refund the amount to my original mode of payment. Thank you
