Well I booted up after my first time building. 16gb of ram? I ordered 8. Okay.... well that was a lucky mistake :-) 2133mhz ramn ... 16 gb instead of 8. Either way I love the build more so now. Amazing. Have yet to run anything on it but all the drivers are up to date. Buyer so far = happy. Always wanted a powerful machine in a nondescript case. Yee haw.
