Problem with 64GB of RAM showing up as only 32GB RAM on GA-AX370-Gaming K7 motherboard

Problem with 64GB of RAM in the form of 4 x 16GB modules showing up as only 32GB (31.xGB useable) was finally resolved when I followed this seemingly strange procedure on youtube: https://www.youtube.com/watch?v=oFK2eB51_Ss It basically changed a single setting in the registry; then check that someone has not told "msconfig.exe" to use a limited amount of the available RAM (a legitimate process used by software and hardware testers and developers); then swapped the DIMM order. I had the same problem with running all these 3 OS's: Windows 7, Windows Server 2016 and Windows 10 Pro, so I think this is mainly associated with the DIMM order or imperfect seating causing some issue.  Perhaps it is to do with two slightly different batches of DIMM's.  I initially ordered 2 x 16GB (32GB) installed them and then added another 2 a few weeks later from another source, without considering the pairing in appropriate corresponding slots.

Setting up the HOOK mechanism in libvirt for KVM/QEMU to manage customized networking requirements

This post is a belated follow-up to a post I did 3 years ago about configuring Linux KVM networking to use IP forwarding when IP spoofing is disallowed by your dedicated Linux server provider.  Such as 1and1 in my case.

Migrating/cloning an Apple MAC OSX with Windows 7 / 8 / 10 Bootcamp partition to another hard or solid state (HDD / SSD) disk drive (Updated March 2018)

I got a Mac Book Pro 13" in 2012 that in 2016 I upgraded to a 240GB SSD from a similar sized 250GB HDD.  Since then I have followed this procedure a number of time for friends and customers. This week I again had to upgrade that same Mac Book Pro from the 240GB SSD to a new 480GB SSD and again came across a number of problems.  For this reason, I have decided to invest my time in documenting this troublesome process for the benefit of others and so next time I have to do it I won't have to remember and re-discover everything again. TL;DR - The Crux of this article is that unfortunately, there is no easy way to just copy the whole old drive, with the different Mac and Windows Bootcamp partitions to a new drive. However, with this guide, the complex process is fully explained and broken up into five manageable and easy to understand processes along with their individual steps to do so. NOTE : I use the word ' drive ' loosely here but these processes could work to/or
