Tuetuopay Posted October 30, 2013 Share Posted October 30, 2013 Hello, In around mid-June I bought this kit of memory on Amazon : CMSA8GX3M2A1333C9, which is a DDR3 soDIMM kit with 2x4GB sticks at 1333MHz. I bought this because it was the cheapest (at the time, was 35€, 70€ now) and it was Corsair (I already own Corsair memory in my main rig). When I received it (6th of July, damn you Amazon, you shipped it from Italy for France :confused: ...), I mounted it on my MacBook Pro, mid 2009 model. But there comes the problem. The laptop didn't booted up at all ! I tried several things : - Only one stick, tried both, still no boot :sigh!: - One 4GB stick plus one of the old (2GB) sticks in every combination, still no boot :[pouts: I didn't heard at all the typical Mac bootup sound (at BIOS time). I'm pretty sure it is not a frequency issue, even if my mac is officially certified for 1066MHz DDR3 since it is currently running with a 1333MHz 4GB kit just fine, and at 1333MHz, as said by the system infos :confused: : http://tuetuopay.legtux.org/upload/Tuetuopay/468791/AboutMyMac.png I'm also sure the problem is not from the capacity, my MacBook Pro is supporting up to 8GB according both to Apple and Crucial's tool (or maybe it was from Corsair, whatever :D:). What makes me think I received a dead or defective kit is that I tested it on two others laptops, both supporting 1333MHz according to the constructors, and the system didn't booted up on them neither. I only managed to boot once on Memtest86+ on a friend's Asus ROG G56 (I think, the generation with GTX 4xx and intel's first i5 generation), and it crashed nearly one second after the test actually appeared (plain blue with memtest's stuff) :mad::mad: So, what's the best option for me ? Make another test to confirm the diagnostic :p: ? Send it bac to Amazon or Corsair ? Im pretty mad at this memory right now, it cost me 35€ but these kinds of kits are getting expensive nowadays :roll: Thanks in advance :) Link to comment Share on other sites More sharing options...
