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:

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.

Motherboard: GA-AX370-Gaming K7 (rev. 1.0)
https://www.gigabyte.com/Motherboard/GA-AX370-Gaming-K7-rev-10#support-doc
DIMM's: CRUCIAL 16GB 2Rx8 CT16G4WFD824A.18FB1 DS Micron CL17 1.2v 2400MHz
These were selected from the Supported Memory Test List for their ECC support capability on this non-server motherboard.
For details on how ECC works with Ryzen refer to this very good article

Install or Reinstall TeamViewer 11/12/13 Personal (Non-Commercial) License on Windows Server (2012/2012 R2/2016 etc) [Updated Dec 2017]

After running out of the TeamViewer commercial trial period I sought to find a solution to the problem of having to buy an expensive licence for my home server (which is only used for non-commercial personal use).[Update Dec 2017]: I can confirm that these procedures still apply and work with Teamviewer version 12 and 13 also (as tested on Windows Server 2016).
Procedure A: If TeamViewer is NOT Already Installed (Note: If it is already installed, then first follow procedure B. below)Download and Run the installer downloaded from http://www.teamviewer.com/. On the Welcome to TeamViewer page be sure to check the "Show advanced settings" check box (outlined in red at bottom left in picture), then click "Accept - next". Leave the "Advanced settings" installation window open (as shown above) and start Windows Explorer (i.e. the file manager, not Internet Explorer). Now go to your temp directory by typing "%tmp%" into the location bar and hitting enter.…

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 from eit…

Removing the WLAN / WiFi pcie card whitelist on Lenovo IdeaPad u410 Touch with BIOS update

WARNING! PLEASE READ THE ENTIRE POSTBEFORE USING / DOING ANYTHING!

BACKGROUND
I recently (early 2016) acquired a 2013 Lenovo IdeaPad u410 Touch.

It was not my first choice but still useful but I wanted to upgrade it to more recent tech and make it more usable as it is not the fastest CPU around, i.e. an i5-3337U dual core (quad thread) at 1.8GHz.
http://ark.intel.com/products/72055/Intel-Core-i5-3337U-Processor-3M-Cache-up-to-2_70-GHz


First thing I did was upgrade the BIOS to latest (as anyone would/should do really) version 65CN99WW (8/28/2014) available here:
http://support.lenovo.com/au/en/products/laptops-and-netbooks/ideapad-u-series-laptops/ideapad-u410?beta=false

I then added 2 x Kingston SO-DIMM KVR16LS11/8 1.35V (Low Voltage) 8G DDR3 1600 Notebook Ram SODIMM's despite the specs I could find all saying it would only take 8GB and it works fine with the 16GB as the Intel i5-3337U CPU (says 32GB) & Mobile Intel HM77 Express Chipset specifications suggest.
