Five memory kits compared, from the SP Turbine to the Trident Z5 Royal Neo, with the trade-offs of each named.
By The PC Journal editorial team
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.

Best for
- Keeping the budget tight.
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 64GB at CL16. It matches the PNY Low Profile, the Trident Z5 Royal Neo and the Trident Z5 Neo CL28 on capacity (32GB (2 sticks)). Like the PNY Low Profile and Vengeance LPX 64GB, 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 was the cheapest of the group when we checked; the PNY Low Profile was the next step up. The main gap: rated speed of 3200MT/s, behind the Trident Z5 Royal Neo (6000MT/s). If that matters, the Trident Z5 Royal Neo offers 6000MT/s.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Fit
- We noted RGB and low-profile heatspreaders where listed.
- Capacity
- We focused on two-stick 32GB and 64GB kits.
- Speed and timings
- We compared listed speed and CAS latency.
- Profiles
- We checked for AMD EXPO and Intel XMP support.
What to Look for in a Low-Latency RAM
Key buying criteria so you get the right fit the first time.
How much rated speed you need
Among these picks, rated speed runs from 3200MT/s on the Vengeance LPX 64GB to 6000MT/s on the Trident Z5 Royal Neo. Match this to what you will actually do with it, then let price decide between the picks that qualify.
DDR5-6000 is the AM5 sweet spot
AMD's Ryzen 7000 and 9000 chips run memory in sync up to about 6000MT/s. Faster kits often fall out of that sync and gain little.
Intel Core Ultra chips handle higher speeds more comfortably.
32GB is the gaming default
32GB covers games with browsers and chat running. 64GB suits video editing, large projects and heavy multitasking.
Check for EXPO or XMP
EXPO profiles set speed and timings in one click on AMD boards; XMP does the same on Intel. Many kits carry both.
16GB is the floor, not the target
A 16GB two-stick kit runs most games but leaves little room for a browser and chat in the background. Plan to move to 32GB when budget allows.

Frequently Asked Questions
How do these memory kits compare on CAS latency?
The SP Turbine leads at CL16, ahead of the PNY Low Profile at CL16; the Trident Z5 Neo CL28 sits at the other end with CL28.
Which is the cheapest pick in this guide?
Start with the SP Turbine, the lowest-priced pick when we checked. The Trident Z5 Royal Neo is the premium end, so the spread between them shows what extra money buys here.
Is DDR5-8000 worth it?
On AM5, rarely; it often runs out of sync with the memory controller. It suits Intel builds tuned for high speeds.
What happens if I don't enable EXPO or XMP?
The kit runs at a slower default speed. Enable the profile in the BIOS to get the rated speed.
Can I mix two kits?
It often fails to run at rated speed. Buy one kit with all the capacity you need.
Bottom Line
Our first pick is the SP Turbine, chosen for the lowest price of the group at our last check. Look at the PNY Low Profile for a low-profile design, the Vengeance LPX 64GB for the largest capacity here (64GB (2 sticks)) and the Trident Z5 Royal Neo for timings of 26-36-36-96 at the highest price in the group if those matter more to you.
Enable EXPO or XMP in the BIOS, or the kit runs at base speed.
