Product Information
Full details
The G.Skill Ripjaws V 64GB (2 x 32GB) DDR4 4000MHz memory kit is an ideal choice for power users, video editors, and gamers who need massive capacity and high-speed data throughput. By providing a stable, dual-channel high-performance solution, it helps significantly reduce rendering and loading times in intensive applications, though users should ensure their motherboard and CPU architecture natively support the 4000MHz frequency before purchasing.

Extended Product Information
FAQs
Is this memory compatible with AMD Ryzen systems?
While optimized for Intel, it can work with AMD; however, 4000MHz might require manual tuning of the Infinity Fabric clock for stability on AMD platforms.
What is the module height?
The modules are 42mm tall, which is compatible with most aftermarket air coolers.
Do I need to enable anything to get 4000MHz speeds?
Yes, you must enable XMP 2.0 in your BIOS; otherwise, the RAM will run at the default JEDEC speed.
Are these ECC memory modules?
No, these are non-ECC, unbuffered memory modules intended for PC/Server usage.
Can I mix this kit with my existing RAM?
Mixing memory kits is not recommended as it can lead to instability and difficulty reaching the rated XMP speeds.
Troubleshooting
System fails to boot after enabling XMP
Clear CMOS to reset BIOS settings, then update your motherboard BIOS to the latest version before re-enabling XMP.
Memory is running at a lower speed (e.g., 2133MHz or 2666MHz)
Enter the BIOS and ensure the XMP 2.0 profile is manually selected; the system defaults to slower speeds automatically for safety.
System instability or blue screens under load
Run a memory diagnostic tool like MemTest86 to check for faulty sectors and ensure the memory is seated firmly in the dual-channel slots.
Pros and Cons
Pros
- Large 64GB capacity for heavy rendering and multitasking
- High 4000MHz frequency for low-latency system performance
- Easy overclocking via XMP 2.0 profiles
- Universal 42mm height avoids clearance issues with most coolers
Cons
- Requires high-end motherboard support for 4000MHz speeds
- Higher voltage requirements compared to standard 3200MHz kits
- Not intended for basic office workstations
Setup, Compatibility & Care
Installation requires standard DDR4 motherboard slots. Once physically installed, the system will likely default to a lower JEDEC speed for stability. To achieve the advertised 4000MHz speed, you must enter your system BIOS (usually by pressing Del or F2 during boot) and locate the XMP settings. Enable 'Profile 1' to apply the optimized speed and latency settings automatically. Ensure that your CPU's integrated memory controller is capable of handling the 4000MHz frequency, as performance can vary by processor generation. When handling the modules, hold them by the edges to avoid touching the gold contact pins, and keep the area free of dust to maintain optimal conductivity.
