It should be fine. If you've got more than 2 sockets, check you're using the correct 2 for dual channel.

Personally I would go into the BIOS after installing them and check the timings, speed and volts are correct, but that shouldn't be necessary. Maybe check them in CPU-Z once installed; see how the 'memory' tab compares with the 'SPD' tab.

The packet will tell you the timings if you want to check against the BIOS. It'll be something like 5/5/5/15 or 8/8/8/24.

Based on a lot of results so far (myself included), you may have to manually set the RAM.
I have 1066 RAM but they defaulted to 800 on post.
