Dimension Scores
The 4000MT/s speed with CL18 timings is among the faster options available for DDR4 memory, offering a performance boost for demanding tasks.
It's optimized for modern Intel Z490+ and AMD Ryzen X570/B550 platforms, but older Ryzen CPUs or non-QVL motherboards might struggle to reach advertised XMP speeds.
XMP 2.0 provides easy overclocking to 4000MT/s CL18, but manual overclocking beyond that might be limited as it's not guaranteed to be Samsung B-die.
While G.SKILL is generally a reputable brand, some anecdotal user reports mention stability issues or stick failures, though overall ratings are high.
Best For
- High-performance gaming rigs seeking fast DDR4 memory
- Workstations handling video editing or other demanding applications that benefit from 32GB RAM
- PC builders prioritizing customizable RGB aesthetics in their system
- Users with compatible Intel Z490+ or AMD Ryzen X570/B550 motherboards
Not Recommended For
- Budget-conscious builds where 4000MT/s CL18 is overkill
- Users unwilling to enable XMP in BIOS for advertised performance
- Systems with motherboards not listed on G.SKILL's QVL for this specific kit
- Enthusiasts who require guaranteed Samsung B-die for advanced manual memory tuning
Watch Out For
- Achieving the advertised 4000MT/s CL18 speeds requires enabling the XMP profile in your motherboard's BIOS.
- This kit is not guaranteed to use Samsung B-die chips, which can limit its potential for extreme manual overclocking beyond XMP settings.
- Mixing this memory kit with other kits, even identical ones purchased separately, can lead to system instability or failure.
- Some users on Reddit have reported anecdotal issues with G.SKILL RAM, including sticks failing after 1.5 years, though experiences vary.
- Older or specific AMD Ryzen CPUs might struggle to run this RAM at its full 4000MT/s XMP profile, potentially requiring manual tuning to lower speeds like 3800MHz for stability.

What Buyers Say
Users frequently highlight the visual appeal of the customizable RGB lighting and the performance gains this RAM provides for gaming and demanding applications. A common point of discussion is the necessity of enabling XMP in the BIOS to achieve the advertised 4000MT/s speeds, with some users needing to tweak settings for stability, especially on certain AMD platforms. While many report seamless operation, a few anecdotal complaints surface regarding compatibility or long-term reliability.
“Got these for my new build, RGB looks sick and they're fast, but I had to mess with my BIOS for a bit to get them to actually hit 4000MHz, almost thought they were broken.”
Common Praise
- The 4000MT/s speed significantly enhances system performance for gaming and multitasking
- Customizable RGB lighting looks phenomenal and can be synchronized with motherboard software
- Provides a noticeable performance boost for demanding applications like video editing
- Easy to install and fits well into PC builds
- Supports dual-channel architecture, boosting memory bandwidth
Common Complaints
- Requires manual enabling of XMP in BIOS to reach advertised 4000MHz, not plug-and-play at full speed
- Some users with Ryzen CPUs found it challenging to run at full XMP speeds, sometimes needing to downclock to 3800MHz
- Not guaranteed to be Samsung B-die, which can disappoint enthusiasts looking for maximum manual overclocking
- Anecdotal reports of individual sticks failing after a year or two of use
Ownership Tips
- You absolutely have to go into your motherboard's BIOS and enable the XMP profile to get the 4000MT/s speed; it won't run that fast by default.
- The RGB lighting is controllable through your motherboard's software (like ASUS Aura Sync or MSI Mystic Light), allowing for synchronization with other components.
- Checking your motherboard's Qualified Vendor List (QVL) on G.SKILL's website before buying can save you headaches with compatibility and stability.
- Even if your CPU and motherboard support 4000MT/s, sometimes minor voltage tweaks or timings adjustments are needed for rock-solid stability, especially on AMD platforms.
Frequently Asked Questions

Buying Guide
When you're looking at RAM, you need to understand that speed (MT/s) and latency (CL) work together. Higher speeds are generally better, but lower latency is also crucial for how quickly your CPU can access data. Don't just look at one number; consider both. Also, XMP isn't magic; it's a pre-configured overclocking profile you need to activate in your BIOS.
Speed (4000MT/s)
This number tells you how many data transfers the RAM can perform per second. Think of it like the speed limit on a highway; a higher number means data can move faster, which is especially beneficial for gaming and CPU-intensive tasks.
Latency (CL18)
CAS Latency (CL) is the delay, measured in clock cycles, between when the CPU requests data and when the RAM starts sending it. Imagine it as the reaction time of the RAM; a lower CL number means less delay and quicker responses.
Voltage (1.40V)
This is the electrical power required for the RAM to operate at its advertised speed and latency. Your motherboard needs to be able to supply this voltage, and you'll typically set it automatically by enabling XMP.
Alternatives
If this kit is too expensive or your system struggles with 4000MT/s, consider DDR4 kits around 3600MT/s with CL16 or CL18 timings for a balance of performance and cost. For maximum raw speed in competitive scenarios, look for kits with even lower CL timings at high speeds, often indicating premium memory chips.
