Thank you for contacting us in regards to your question.

4200MHz is an overclocked memory frequency.  While not officially supported by Intel directly, certain motherboards are rated to help in reaching these frequencies.  For more information, we would suggest consulting your motherboard manual.

Question 3

Windows 7 Compatible?

Accepted Answer

Yes, I am currently running Windows 7 Ultimate since purchasing this, with no issues.

Question 4

how much better is this for gaming than a i7 7820x?

Accepted Answer

Gaming will likely run faster on a 4 to 8 core CPU as most games rarely use more than a couple of threads and benefit greatly from Turbo Boost rather than a lot of threads hanging out there. This CPU is made for a production environment more than gaming. It works well for either, but is not your best option from a performance standpoint, nor a price to performance ratio angle. I have this processor for After Effects and post video production and unless you are a Twitch streamer, you can see significant improvements for gaming on an X99 platform rather than an X299 chipset and put your money into the video card rather than a huge amount of multi threading. I hope that helps. :D
