My question is why would you underclock it if you plan to use it as a server? You need the CPU power to be constantly running at it's best.
Nononono, the 630 is the server; it's running full speed.
The 620 is literally just for school now at this point.
Also laptops shouldn't be used as a server. They overheat really quickly. A normal cheap desktop could do that job.
This has been going fine at about 120F for 17 days straight as of now, ~150 under heavy load.
Plus I used that normally for about 2 years with really heavy tasks anyways, it's fine.
And no, I was using an older computer with a 700MHz CPU and the load it was taking was just something it couldn't keep up with. That and it sucked up power ridiculously bad.
