Just bought 2 4GB sticks of DDR2 RAM, and they don't fit in my motherboard. The new sticks are Komputerbay 240 Pin 800MHz PC2-6400F DDR2 ECC Fully Buffered FB-DIMM Memory Modules (on the bottom in the picture), and my old sticks are Geil PC2-8500 DDR2-1066 Memory Modules (on the top in the picture). My motherboard is an ASRock N68C-GS4FX. My guess was that the new motherboard required non-ECC momory, but I really don't know.

    Yes, your motherboard only supports non-ECC, un-buffered memory. Here are the specifications for your motherboard. – MC10 Aug 9 '15 at 19:04
  • if they dont fit, they are wrong, always. take that as life law. – Francisco Tapia Sep 11 '15 at 14:33
  • The lower label is funny. Unbufffered 240 pin unbuffered dual in-line memory module. They are making very sure it is not registered memory. :) – Hennes Sep 11 '15 at 16:03

It looks like you bought Fully Buffered DDR2, which is not compatible with DDR2 slots.

If you need further information, you can start with this Wikipedia article

240-pin DDR2 FB-DIMMs are notched differently from conventional 240-pin DDR2 DIMMs. As a result, those two DIMM types are neither mechanically nor electrically compatible.

If you somehow ended up with a boatload of the Fully Buffered DDR2 RAM (different architecture than standard DDR2) you might want to consider purchasing a used HP XW6400 Workstation Computer - around $100-$150 refurbished on eBay. They take the Fully Buffered ECC Memory and Max out at 16gb. Makes for a superfast desktop replacement PC, faster than anything I've seen new if you get one with a Quadcore.

  • Your answer is good, i personally avoid to speak about money or prices because they go out to date pretty soon. fix it and i'll upvote. – Francisco Tapia Sep 11 '15 at 14:54
