Enhancing PC Performance: Adding 8GB RAM (2x4) to 16GB RAM (2x8) gaming PC bundle


Gaming PC bundle Your RAM slots aren't channels. Most motherboards have 2 RAM slots per channel.

If your motherboard supports 4 memory channels, adding 2x4GB can enhance your PC's performance, unless you have a very old motherboard (e.g., DDR2). In such cases, stick with 2x8GB or upgrade to 4x8GB.

For mainstream motherboards with 4 memory slots and 2 channels, adding 2x4GB can boost your PC, provided the new RAM isn't significantly slower than your current one or your CPU's memory controller can't handle the added RAM speed.

Full Answer:

Upgrading your PC's RAM configuration is a smart move if your motherboard supports quad-channel RAM and flex mode. This enhancement can lead to an overall performance boost gaming PC bundle. With 2x4GB added to your setup, you'd create a 24GB flex-mode configuration, with 16GB operating in quad-channel mode and the remaining 8GB in dual-channel mode once the quad-channel capacity is exhausted.

However, if you're using an older quad-channel DDR2 motherboard, like an Intel S5400SF server motherboard, it might not support flex mode. In such cases, it's generally recommended to stick with 2x8GB. Installing modules of different capacities in these motherboards could lead to compatibility issues, potentially rendering your PC inoperable or forcing it into single-channel mode for the entire RAM capacity.

Typically, only motherboards designed for "HEDT" (High-End DeskTop) workstations and servers offer more than 2 memory channels. These high-end motherboards often come with 8 RAM slots. In cases where you install 4 memory modules into a modern dual-channel motherboard, it will still run in dual-channel mode, but the extra memory capacity can be beneficial.

If you currently have 2x8GB in dual-channel mode, you can install two 4GB modules into the empty RAM slots to reach 12GB in each memory channel, creating "full" dual-channel mode. This setup also offers a latency reduction due to data interleaving between the two modules within each channel, enhancing performance.

To achieve a similar benefit of interleaving, you can opt for dual-rank RAM modules. Dual-rank RAM modules contain two rows of chips (usually one on each side). Each rank/row of chips functions as an independent module gaming PC bundle. In mainstream motherboards, you can have up to 4 ranks of memory in each channel by installing 4 dual-rank modules. While all 8GB DDR3 desktop RAM modules are dual-rank, some older DDR4 modules also fall into this category. However, it's essential to check the rank configuration, which is not always specified for high-end gaming RAM.

Matching the transfer rate (advertised MHz) and CAS Latency (CL) of your RAM is crucial. By default, all your RAM will run at the speed of the slowest module. High-voltage/gaming RAM may initially default to a slow JEDEC speed profile when you install more RAM. In such cases, you'll need to access the BIOS to enable the XMP/DOCP/EXPO speed profile or manually configure the RAM to the correct transfer rate, latency, and voltage. Note that some laptops and prebuilt desktop PCs (e.g., most Dell PCs) may not allow you to adjust RAM speed or voltage settings, limiting you to a slow JEDEC RAM speed.

Additionally, if your CPU has a weaker memory controller and your RAM is relatively fast gaming PC bundle, adding more RAM modules may lead to instability or booting issues. The interleaving of data between modules reduces latency but also increases the load on the memory controller. If your memory controller can't handle it, you might experience errors. In such cases, underclocking the RAM can provide stability but may reduce RAM bandwidth.

CPU memory controller performance can vary, even among the same model of CPUs. For instance, while most Ryzen 5 1600 CPUs can work with 1 module per channel at DDR4–3200, they may struggle with 2 modules per channel at the same speed, especially if the modules are dual-rank. However, some Ryzen 5 1600 CPUs can handle 4 RAM modules at DDR4–3200 without issues.

Building the Ultimate PC for Lag-Free Space Engineers Gameplay"

If you're an avid Space Engineers player and you're tired of lag disrupting your interstellar adventures, it's time to consider building a PC that can handle the game's demanding requirements. Space Engineers offers both minimum and recommended system specifications, but to truly eliminate lag, you'll want to focus on key components, especially the processor.

Minimum Requirements:

DirectX: 11

Hard Drive: 25 GB free HDD space

Sound Card: DirectX® compatible on-board

Recommended Requirements:

Memory: 16 GB RAM

DirectX: 11

Hard Drive: 25 GB free HDD space

Sound Card: DirectX® compatible on-board

Now, let's focus on the key differentiator between these two sets of requirements: the processor.


The Processor Makes the Difference:


In contrast, the recommended setting suggests an Intel Quad Core i7 running at a blistering 4.5 GHz or its AMD counterpart. This processor boasts four cores, each clocked at 4.5 GHz, resulting in a combined processing power of 18 GHz. That's triple the processing power compared to the minimum requirement.

While upgrading your RAM can provide some benefits, especially when dealing with complex structures in the gaming Pc bundle, it's clear that the processor is the primary bottleneck in Space Engineers. Investing in a powerful processor will significantly enhance your gameplay experience.


To ensure a lag-free and enjoyable Space Engineers experience, allocate your budget wisely when building your gaming PC bundle. While meeting the minimum requirements is possible, upgrading to a quad-core processor, as recommended, will provide you with the processing power needed to handle the game's demands seamlessly.


Whether you're constructing vast space colonies with friends or facing off against swarms of kinetic drones, a powerful processor will keep your gameplay smooth and exhilarating, without the frustrating interruptions caused by lag spikes. So, when building your ultimate Space Engineers PC, remember that more processor power means more gaming fun.
