Hi all,

This is a strange one, I have a Gigabyte GA-Z68XP-UD3P motherboard that I bought since new - I decided I wanted to move from 20gb to 32gb so I bought 2 x 8gb Corsair CMZ16GX3M2A1600C10 Vengeance which is the exact same ram as I had previously so all 4 sticks are 4 x CMZ16GX3M2A1600C10 incase of incompatibility issues.

Now when I boot the PC it gets stuck on Windows is starting with the logo but doesn't move at all even after 20 mins.

I checked the BIOS and it does report all 32gb installed without issue.

So I decided to remove a stick and it boots without issue, so I swap around the DIMMS incase its a slot issue but it appears not.

Now this is when it starts to get interesting...I can boot an ubuntu live disk and all 32gb is registered from the get go.

I have upgraded to BIOS revision F7

Does anyone know why I can't boot windows when all 4 slots have the modules?

Thanks in advance
