G.Skill Trident Z5 Royal S 32GB (2x16GB) DDR5-6400 CL32 Desktop RAM Kit
The G.Skill Trident Z5 Royal S (F5-6400J3239G16GX2-TR5S) is a 32GB (2 x 16GB) DDR5-6400 dual-channel desktop memory kit built and tested for Intel platforms, running at CL32-39-39-102 timings and 1.40V with Intel XMP 3.0 support. It suits anyone building or upgrading an Intel desktop PC who wants a matched, pre-tested kit rather than mixing individual sticks.
Compatibility — what this kit works with
This kit is tuned specifically for Intel desktop platforms. G.Skill lists an Intel XMP 3.0 profile only for this SKU, with no AMD EXPO profile — so if you're building on an AMD Ryzen board, look for a G.Skill kit that specifically lists EXPO support instead of this one.
- Standard desktop DDR5 UDIMM — not a SO-DIMM, so it won't fit laptops
- Non-ECC, Unbuffered — built for consumer desktop builds, not ECC workstation or server boards
- Runs at 4800 MT/s (JEDEC default, 1.10V) on any DDR5 board out of the box; reaches the rated 6400 MT/s once the XMP 3.0 profile is enabled in BIOS

What's in the box
Two 16GB DDR5 modules, sold and validated together as one matched kit. No cooling fan is included, which is normal for a kit at this height.
Why this is the right pick
You get a pair of modules G.Skill has already tested together at the rated speed and timings, rather than two sticks that might not play well together. The mirrored aluminum heatspreader and RGB light bar are built for visible builds, but the specs — 32GB, DDR5-6400, CL32-39-39-102, Intel XMP 3.0 — are what actually determine whether it fits your system and performs as advertised.
Is this RAM compatible with AMD Ryzen systems?
No — G.Skill lists an Intel XMP 3.0 profile only for this kit, with no AMD EXPO profile. It's built and tested for Intel desktop platforms; AMD builders should look for a G.Skill kit that specifically lists EXPO support.
Why is my RAM running slower than 6400 MT/s?
By default this kit runs at its JEDEC standard speed of 4800 MT/s at 1.10V — the rated 6400 MT/s at CL32-39-39-102 only applies once you enable the XMP 3.0 profile in your motherboard's BIOS. If speeds are still low after enabling XMP, confirm your motherboard and CPU officially support DDR5-6400.
What do the timings "CL32-39-39-102" actually mean?
These are the module's tested latency timings at the rated 6400 MT/s speed, with CL32 (CAS Latency 32) as the headline figure — the lower this number, the less delay between a memory request and the data being ready. G.Skill tests these exact timings at 1.40V for this specific kit.
Is this one stick or a matched pair?
It's a matched Dual Channel Kit of two 16GB modules (32GB total), tested together by G.Skill to run at the rated speed and timings. Installing both in the correct dual-channel slots on your motherboard gives you the full rated bandwidth.
Does this support ECC memory?
No, it's Non-ECC and Unbuffered, which is standard for desktop gaming and productivity builds. If your board or workstation requires ECC or Registered memory, this kit isn't the right fit.
Can I use this in a laptop?
No — this is a standard desktop DIMM kit, not a SO-DIMM, so it won't physically fit laptop memory slots. It's designed for desktop motherboards with standard DDR5 DIMM slots.
What warranty does this RAM kit come with?
It's covered by G.Skill's Limited Lifetime Warranty. Keep your proof of purchase from Ink and Rolls in case you ever need to make a claim.
Does it come with a cooling fan?
No — per G.Skill's spec sheet, this model doesn't ship with a memory fan, which is normal for most desktop DDR5 kits at this height.
