DDR4 RAM Specs Compared
Compatible device
You need to match the memory to your system type. The TEAMGROUP Elite is designed for desktop PCs. It uses a UDIMM form factor, which is standard for tower and desktop cases. The OLOy module is built for laptops. It uses a SODIMM form factor, which is smaller and fits into portable computers. You cannot swap these modules. A desktop UDIMM will not fit in a laptop slot, and a laptop SODIMM will not fit in a desktop motherboard. Choose based on your hardware. If you have a laptop, you must pick the OLOy. If you have a desktop, you must pick the TEAMGROUP.
Memory speed
Speed affects how fast data moves between the RAM and the CPU. The TEAMGROUP Elite runs at 2666MHz. This is a common speed for modern desktop systems. The OLOy module runs at 2400MHz. This is a standard speed for many laptops. Higher numbers generally mean better performance in bandwidth-heavy tasks. The TEAMGROUP has a 266MHz advantage here. This difference may be noticeable in gaming or large file transfers on a desktop. The OLOy speed is sufficient for typical laptop workloads, but it is slower than the desktop option. If speed is your priority and you are building a desktop, the TEAMGROUP is the faster choice.
Form factor
The physical shape of the memory stick determines compatibility. The TEAMGROUP Elite is a 288-pin UDIMM. This is the standard unbuffered DIMM for desktop computers. It is longer and has more pins. The OLOy is a 260-pin SODIMM. This is the Small Outline DIMM used in laptops and small form factor PCs. It is shorter and thinner. The pin count and size are different. You cannot install either stick in the wrong type of computer. The TEAMGROUP is built for the larger desktop environment. The OLOy is built for the compact laptop environment. Your choice depends entirely on whether you are upgrading a desktop or a laptop.
CAS latency
CAS Latency (CL) measures the delay before data is accessed. Lower numbers are better. The TEAMGROUP Elite has a CL19 latency. The OLOy module has a CL17 latency. The OLOy has a lower number, meaning it responds slightly faster once a request is made. However, the TEAMGROUP has a higher clock speed. The combination of speed and latency affects real-world performance. The OLOy wins on pure latency specs. The TEAMGROUP wins on frequency. For a desktop user, the higher speed of the TEAMGROUP often outweighs the slightly higher latency. For a laptop user, the OLOy latency is competitive for its class. The OLOy has the edge on this specific metric.
Voltage
Voltage indicates the power required to run the memory. Both the TEAMGROUP Elite and the OLOy module operate at 1.2V. This is the standard voltage for DDR4 memory. It is lower than older DDR3 standards, which helps with energy efficiency and heat generation. Since both products use the same voltage, there is no difference in power consumption or compatibility regarding voltage requirements. You do not need to worry about this spec when choosing between them. Both are safe for standard DDR4 slots. This aspect is a complete tie. Neither product offers a advantage or disadvantage in terms of power usage.
Which DDR4 RAM kit fits your needs
Desktop PC users seeking standard compatibility
Choose this TEAMGROUP module for your desktop tower. It uses the standard UDIMM form factor, ensuring it fits standard motherboard slots. The 2666MHz speed and CL19 latency provide reliable performance for everyday computing tasks. It operates at 1.2V, which helps manage heat in a desktop case.
Laptop owners needing upgrade memory
Select this OLOy stick if you are upgrading a laptop. It is a SODIMM, the specific form factor required for portable computers. The 2400MHz speed with CL17 latency offers efficient operation within the tight thermal constraints of a laptop chassis. It is built to fit the smaller internal slots.
Users wanting motherboard QVL approval
This TEAMGROUP RAM is approved by mainstream motherboard manufacturers for its QVL status. This means it has been tested for compatibility with many desktop boards. If you want assurance that the 8GB UDIMM will work with your existing desktop system without instability, this specification provides a clear advantage.

Frequently asked questions
Can I use the TEAMGROUP Elite in my laptop?
No, you cannot. The TEAMGROUP Elite uses a UDIMM form factor, which is designed for desktop PCs and towers. Laptops require SODIMM modules, like the OLOy option. Using the wrong form factor will prevent the memory from fitting into your system's slots. You must match the physical shape to your device type.
Does either RAM stick support ECC?
No, neither module supports ECC. Both the TEAMGROUP Elite and the OLOy stick are listed as Non-ECC. This means they do not include error-correcting code features found in server-grade memory. For standard desktop and laptop upgrades, Non-ECC is the typical and sufficient choice for most users.
What is the voltage requirement for these kits?
Both kits operate at 1.2V. This is the standard voltage for DDR4 memory, ensuring efficient power usage and heat management. You do not need to worry about higher voltage requirements that might stress older components. Both the TEAMGROUP and OLOy modules adhere to this standard specification.
Is the TEAMGROUP RAM single or dual channel?
The TEAMGROUP Elite is a single-channel module. It is sold as an 8GB kit containing one 8GB stick. To achieve dual-channel performance, you would need to purchase a second identical module. The product data specifies single-channel capacity, meaning it runs on one memory channel by default.
How fast is the OLOy laptop RAM?
The OLOy RAM runs at 2400MHz. This speed is suitable for basic laptop upgrades and older systems that do not support higher frequencies. While slower than desktop options, it provides reliable performance for general computing tasks. It matches the requirements for many standard notebook motherboards.
What is the CAS latency for the TEAMGROUP stick?
The TEAMGROUP Elite has a CAS latency of CL19. This timing value indicates how long the memory takes to respond to a command. Combined with its 2666MHz speed, it offers standard performance for desktop upgrades. Lower latency generally improves responsiveness, but CL19 is typical for this speed tier.
Which RAM is better for gaming?
The TEAMGROUP Elite is the better choice for gaming. It offers 2666MHz speed, which is faster than the OLOy's 2400MHz. Additionally, it is designed for desktop PCs, which typically have more robust cooling and power delivery for gaming rigs. The OLOy is limited to laptop form factors.
Does the OLOy RAM come in a kit?
The data lists the OLOy item as an 8GB module, not explicitly as a multi-stick kit. It is described as a single unit for laptop upgrades. If you need dual-channel performance, you may need to buy two of these modules separately. The listing focuses on the individual 8GB capacity.
