RAM memory card replacement

問題

It was not a fixing - I Bought 2 RAM memory cards of 4GB to put om my MacBook Pro

修理

Unfortunately it didn't work as expected. It didn't work and I had to put back the old one in place. Luckily the seller will accept the return and give my money back. Before that I was advised to test one card at the time to see which one was defective. It end up being both defective.

アドバイス

I guess when we buy this things its a matter of luck whether this things will work or not. Always make sure deal with honest people like I did, otherwise you will pay the price
