The Best Low-Latency RAM
Five memory kits compared, from the SP Turbine to the Trident Z5 Royal Neo, with the trade-offs of each named.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated
Lower CAS latency at a given speed means faster memory access. Every pick is DDR5 at CL30 or lower, or DDR4 at CL16 or lower, ordered by CAS latency.
This is a research roundup, not a lab test: CAS latency, rated speed and capacity come from each maker's published specs; a missing voltage is flagged, not filled in, and no figure here comes from our own testing.

Our Picks
Lowest Price Here1 of 5
Silicon Power Turbine 32GB (2x16GB) DDR4-3200 CL16
SP Turbine lists DDR4-3200 at CL16 at one of the lowest 32GB prices here.
Best for
- Keeping the cost under $250.
Skip if
- Look at the others if this bothers you: rated speed of 3200MT/s, behind the Trident Z5 Royal Neo (6000MT/s).
Why we like it
On CAS latency it ties with the PNY Low Profile and the Vengeance LPX 32GB at CL16. Like the PNY Low Profile and Vengeance LPX 32GB, it has a DDR4 memory type, while the Trident Z5 Royal Neo uses a DDR5 memory type. It also comes with a plain heatspreader.
Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR4 kit, so it fits AM4 boards and LGA1700 boards sold in DDR4 versions; it does not fit AM5, LGA1851 or any DDR5 board. It was the cheapest of the group when we checked; the PNY Low Profile was the next step up.

PNY 32GB (2x16GB) DDR4-3200 CL16 Low Profile
The PNY Low Profile stands out for a low-profile design.
Best for
- Buyers who want low-profile design.
Skip if
- Skip it if price comes first: the SP Turbine cost less when we checked.
Why we like it
It also offers a CL16 CAS latency and offers a 3200MT/s rated speed. It matches the SP Turbine and the Vengeance LPX 32GB on CAS latency (CL16). It shares a DDR4 memory type with the SP Turbine and Vengeance LPX 32GB; the Trident Z5 Neo CL28 goes with a DDR5 memory type.
Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR4 kit, so it fits AM4 boards and LGA1700 boards sold in DDR4 versions; it does not fit AM5, LGA1851 or any DDR5 board. It was priced above the SP Turbine and below the Vengeance LPX 32GB at the time of writing.

Best for
- Buyers who want timings of 16-20-20-38.
Skip if
- Skip it if rated speed matters most to you; the Trident Z5 Royal Neo offers 6000MT/s.
Why we like it
It matches the SP Turbine and the PNY Low Profile on CAS latency (CL16). You get XMP 2.0 profiles here, which sets it apart from the Trident Z5 Neo CL28 and its EXPO profiles. It shares a DDR4 memory type with the SP Turbine and PNY Low Profile; the Trident Z5 Neo CL28 goes with a DDR5 memory type.
You also get timings of 16-20-20-38. Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR4 kit, so it fits AM4 boards and LGA1700 boards sold in DDR4 versions; it does not fit AM5, LGA1851 or any DDR5 board. When we checked, only the PNY Low Profile and cheaper picks cost less, and the Trident Z5 Neo CL28 cost more.

- Costs more than the SP Turbine at the time of writing
The catch
Rated speed is its weakest area, and the Trident Z5 Royal Neo covers it better at 6000MT/s.
Premium Pick4 of 5
G.SKILL Trident Z5 Royal Neo 32GB (2x16GB) DDR5-6000 CL26
The Trident Z5 Royal Neo runs CL26 at 6000MT/s, the tightest timings here, at 1.45V.
Best for
- Buyers for whom price is not the deciding factor, since the SP Turbine costs less.
Skip if
- Skip it if price comes first: the SP Turbine cost less when we checked.
Why we like it
The gain over CL30 is small on an X3D chip, so it is for enthusiasts. On CAS latency it sits mid-pack at CL26: the SP Turbine offers CL16, and the Trident Z5 Neo CL28 comes in at CL28. On rated speed it ties with the Trident Z5 Neo CL28 at 6000MT/s.
Like the Trident Z5 Neo CL28, it has EXPO profiles, while the Vengeance LPX 32GB uses XMP 2.0 profiles. Like the Trident Z5 Neo CL28, it has a DDR5 memory type, while the PNY Low Profile uses a DDR4 memory type. It also comes with a Royal-series decorative lightbar.
Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR5 kit for AM5, LGA1851 and DDR5 versions of LGA1700 boards; it does not fit DDR4 slots. It was the most expensive pick when we checked, so weigh what it adds over the Trident Z5 Neo CL28.

Worth a Look5 of 5
G.SKILL Trident Z5 Neo RGB 32GB (2x16GB) DDR5-6000 CL28
The Trident Z5 Neo RGB CL28 kit keeps the 9800X3D's preferred 6000MT/s speed with tighter timings than CL30 kits, and an EXPO profile sets it up in one click.
Best for
- Buyers who want timings of 28-36-36-96.
Skip if
- Skip it if CAS latency matters most to you; the SP Turbine offers CL16.
Why we like it
On CAS latency it trails the group at CL28, while the SP Turbine offers CL16. Like the Trident Z5 Royal Neo, it has EXPO profiles, while the Vengeance LPX 32GB uses XMP 2.0 profiles. Like the Trident Z5 Royal Neo, it has a DDR5 memory type, while the Vengeance LPX 32GB uses a DDR4 memory type.
Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR5 kit for AM5, LGA1851 and DDR5 versions of LGA1700 boards; it does not fit DDR4 slots. RGB heatspreaders are taller than plain ones, so check the clearance under a large tower cooler. On price it sat fourth of 5, between the cheaper Vengeance LPX 32GB and the pricier Trident Z5 Royal Neo, at the time of writing.

How We Chose
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- The figures behind the order
- We set side by side five kits on CAS latency, rated speed, capacity and voltage as the makers state them. Nothing was tested in-house; 4 of the 8 fields compared are stated for every pick, while voltage and profiles have gaps.
- The shared baseline
- All 5, from the SP Turbine to the Trident Z5 Neo CL28, state CAS latency, rated speed and capacity.
- Where the specs have gaps
- The PNY Low Profile gives no voltage; the SP Turbine and the PNY Low Profile give no profiles.
- Price range
- At our last check the picks ran from the SP Turbine ($150 to $250) to the Trident Z5 Royal Neo ($500 to $1000).
