Speed Ranking
Top 9%
6400MHz ranks in the top 9% of all DDR5 speeds tracked (1,188 modules).
XMP 3.0 / EXPO Profile Activation Required
This is a high-performance DDR5-6400 memory kit. It will NOT run at advertised speeds out of the box.
JEDEC Fallback Behavior
By default, all motherboards boot using safe **JEDEC standards** (typically **4800MT/s**). If you plug this RAM in and boot immediately, your system will downclock to this baseline, losing up to **10% - 20% CPU bandwidth**.
How to Enable XMP/EXPO
- 1.Reboot PC, tap
DelorF2to enter **BIOS**. - 2.Find memory settings and toggle **XMP / EXPO** to **Enabled**.
- 3.Save & Exit (press
F10). PC will reboot at 6400MHz.

Frequently Asked Questions
Is the 128GB (4x32) 6400MHz DDR5 compatible with my motherboard?
This module is compatible with Intel 12th / 13th / 14th Gen (LGA1700), Intel Core Ultra 200S (LGA1851 / Arrow Lake), AMD Ryzen 7000 / 8000 / 9000 (AM5), AMD Threadripper 7000 (TRX50). Always verify with your motherboard's QVL (Qualified Vendor List) before purchasing, as compatibility can vary by board revision.
Is this DDR5 module a good deal right now?
At $3.09/GB, this module is 70% below the overall DDR5 market average $/GB across all capacities. Check the price history chart above to see how the price has moved recently. Prices are updated daily from Amazon.
What is 6400MHz RAM used for?
This is an ECC (Error-Correcting Code) RAM module designed for servers, workstations, and NAS systems where data integrity is critical. ECC RAM detects and corrects single-bit memory errors automatically. It requires a compatible CPU and motherboard — most consumer platforms do not support ECC. See our ECC RAM guide for platform compatibility details.
How does this brand RAM compare to other brands?
Compare this module against other brands using the RAM comparison tool. Key factors to consider: price per GB, customer ratings, warranty coverage, and compatibility with your specific motherboard.
Is 128GB of RAM enough for gaming in 2026?
128GB is more than enough for gaming in 2026. Most AAA titles use 16–24GB alongside Discord and a browser. 128GB gives you headroom for streaming, recording, and running multiple applications simultaneously.
What is the difference between a single 128GB stick and a 2×64GB kit?
This is already a 4×32GB dual-channel kit — the correct configuration for maximum performance. Dual-channel mode doubles the memory bandwidth by using both memory channels simultaneously, improving performance in games and applications by 10–30% compared to a single stick of the same total capacity.
