Improve your PC performance with ASUS RAMCache III and DDR4 RAM – TweakTown



When I first came to TweakTown almost two decades ago, I came for OS tweaks that I used for overclocking and then applied what I figured out to my work. Over the years, I came to know the staff at TweakTown at events around the world. I am an overclocker, and I work in the additive manufacturing industry. I specialize in industrial 3D scanning and printing. This industry demands high-performance computing to be competitive, let alone to be able to handle the high paying jobs.

I use RAMCache on both my gaming machine and my workstation, it works in most scenarios, and I am yet to find an application that conflict. It’s a simple way to gain SSD or HDD performance by using your computer memory to store repetitively accessed data. Caching software has been around many years, and the technology is solid. I mainly work with Autodesk, where I regularly repair and slice 3D files on demand. I require a high-end desktop to work on jobs that require memory tweaks, and these tricks work well with 8GB or more.

Applications that have libraries or processing dense point cloud data tend to be the most improved along with files pulled from a single archive; this performance improvement comes from after the initial program loads and data has been accessed at least once. If its accessed multiple times, performance will improve but be negligible.


My ASUS X299 Rampage VI Extreme Omega motherboard comes with RAMCache III software that needs to be installed. It helps with reducing disk access, and system performance is improved when it fetches data from memory.



RAMCache III is very simple to install and setup. It comes with ASUS motherboards or can be downloaded at ASUS.com if you own an ASUS motherboard.

By default, memory caching software will install with the caching turned off, so you will need to start the caching software manually. You can use “smart mode” with auto settings, or you can go into advanced mode. Advanced mode lets you change drives and change cache size. Caching must be stopped to go into advanced mode.


The DRAM information tab gives you basic SPD information, and the memory check tab has a quick memory test.


Hard drive and SSD benchmarks are the best way to show the cache software is working, and there are a few popular ones used in reviews today to compare against.

Here’s Crystal Disk Mark 7.0 before and after.


My SSD is an AIC Intel 750; it is no slouch, and clearly, you can see the caching working as expected in this test. The drive benchmark was running from cached memory.

How does this help in games? I play Battlefield 3 and 4, getting to the vehicle first made the game fun for me, yea I am that guy. The vehicles are first come first served, and chances are I am in the vehicle before your computer loads. Yes, a good connection is also key to winning, and so is having a faster SSD in some games. For those with PunkBuster or other anti-cheat detection, this has never been a problem. A quick Google search will show there are no issues.

RAMCache III is transparent to all applications. So far, nothing I use conflicts with it, and I run with cache enabled all the time. Meteorology, scanning, dense cloud processing, spooling, ripping, and slicing are all improved with RAMCache.

Weighing in just over 1TB of data, handling this axle easily was critical when time is money. Being able to handle this file quickly was critical to completing this job on time and under budget. You can use third-party software like PrimoCache to achieve similar results, or I would suggest Samsung’s Rapid Magician if you have and Samsung drive. A quick search on Google should reveal many other options.

If your machine is unstable, I would avoid caching software, as there is the potential of data being lost if something is being transferred and the machine loses power – the data in cache will be lost. I am 100% stable with XMP settings. I rely on high stability. I usually have many applications open at once, and there seems to be no issues caching from the application in focus as well as stuff processing in the background.
