Hi,
I am not the creator of this program, nor do I work with the company releasing it. I've been and I am part of the community from where this software originates.
Been wanting to share this program with a larger crowd for long, but it has been in a semi-closed alpha until now.
Let me present you Ram Test, a simple memory testing utility that is both very effective and accurate (finds errors better then i.e. HCI Memtest) and also very very fast. About 15 times faster then HCI memtest.

The program is made by Karhusoftware, a one man project from Finland. The program was born after the creator, Mustanaamio, got frustrated with how long it took to bench his memory configs with his Ryzen build last summer. He got pissed of enough to actually write his own memory tester, and it has been quite popular in finnish overclocker/computer enthusiast scene since. Mustanaamio sold licenses to Ram Test at io-tech.fi forums when the program was in alpha/beta, and has now released it 'to the wild'.
There is a large community behind this project at https://bbs.io-tech.fi/.
I rate Ram Test as the best memory testing utlity at this time, bar from using linux-mint and google's memorybench. But out of standalone utilities/programs in windows this is by far the most accurate, thorough and FAST. I repeat; about 15 times faster then HCI memtest. And no need to launch multiple instaces of the program! I can push 703% coverage on 12288 megabyte memory-run in 10 minutes, when HCI memtest only does ~45% covera in same time. HUUUUUUGE! Check my video, I show you the two of them against each other
You can skip to 12:00 mark to see how they compare, the beginning of the video is pretty much just showing of the program, and telling some tales about it's origins.
*edit*
A friend aproaced me saying that I should have ran 12 instances of HCI memtest, one per CPU-thread available. So I did a re-test, and the result is the same as the original:

Apologies for bad grammar, I am not a native English speaker but I try to be understandableRAM TEST README
RAM Test is a fast and reliable memory testing software with a graphical user
interface. It can be used to test your system memory for hardware faults or an
unstable overclock.
The software supports up to 8 TB of memory on a 64-bit machine and up to 2 GB
of memory on a 32-bit machine. The testing algorithm scales for up to 64
threads and has optimized code paths for AVX and AVX2 capable processors.
1. SYSTEM REQUIREMENTS
Your system must meet the following requirements to be able to run RAM Test:
* Microsoft Windows 7 or later (supports both 32-bit and 64-bit versions)
* Microsoft .NET Framework 4.5 or later
* A CPU with full SSE2 support
* An internet connection during activation
2. INSTALLATION
RAM Test is a portable software and does not come with an installer. To get
the software up and running, follow the steps below:
1. Unzip the files to any folder in which your user account has full
permissions
2. Run ramtest.exe
3. Activate your license with the product key
4. Start testing
It is possible to "install" the software on a USB flash drive.
3. SETTINGS
Megabytes:
The amount of memory to test in megabytes.
If you have the paging file enabled and you use too large value, the test
may progress very slowly due to the operating system having to cycle pages
through your SSD/HDD.
Threads:
The number of threads to use for testing.
Optimal performance is achieved by specifying a value equal to the
number of processor cores in your system.
Beep on error:
Play a beep sound when a memory error is detected.
Stop on error:
Automatically stop testing when a memory error is detected.
Telemetry:
Allow the collection of the following additional personal and/or
anonymized data each time a test is finished:
* RAM Test version
* RAM Test platform (x64 or x86)
* Value of the megabytes setting
* Value of the threads setting
* Motherboard make and model
* Processor make and model
* Memory make and model
* Test duration
* Test coverage
* Test error count
4. HOW TO USE
Configure the settings to your preference in the graphical user interface and
click the start button to begin testing. To stop testing, just click the same
button again.
It is recommended to run the test for at least 10 minutes before drawing any
conclusions about the stability of your system memory. To detect intermittent
memory errors you should let the test run for at least one hour.
5. CHANGELOG
1.0.0.0 (20.12.2017):
+ Initial release
6. ADDITIONAL INFORMATION
Unstable or faulty memory can cause your computer to crash or worse. DO NOT
RUN THE SOFTWARE IF YOU HAVE ANY UNSAVED WORK OPEN. YOU HAVE BEEN WARNED.
