CL40 vs CL38 DDR5 Specs
Memory Speed
The TEAMGROUP Elite kit operates at a base frequency of 4800MHz. This speed is standard for DDR5 and ensures broad compatibility with most motherboards without requiring manual tuning. In contrast, the TEAMGROUP T-Force Delta RGB runs at 6000MHz. This higher frequency allows for faster data transfer rates, which can improve performance in bandwidth-heavy tasks. You get a significant speed advantage with the T-Force model, as it pushes well beyond the baseline DDR5 standards. This makes it better suited for users seeking maximum throughput out of the box.
CAS Latency
Latency measures the delay before data is available to the CPU. The TEAMGROUP Elite kit has a CAS Latency of CL40. This is a typical value for its 4800MHz speed tier. The TEAMGROUP T-Force Delta RGB features a tighter CAS Latency of CL38. Lower numbers indicate faster response times. Even though the T-Force runs at a higher frequency, its lower latency helps maintain efficiency. You get slightly better responsiveness with the CL38 kit, which can help in scenarios where quick data access is critical for system stability and speed.
Overclocking Profile
The TEAMGROUP Elite DDR5 kit is a standard UDIMM module designed to run at its specified JEDEC speeds. It does not list specific overclocking profiles like XMP or EXPO in its key specifications. The TEAMGROUP T-Force Delta RGB, however, explicitly supports Intel XMP 3.0 and AMD EXPO. These profiles allow you to easily enable higher speeds and optimized timings through your motherboard BIOS. If you want one-click performance upgrades without manual configuration, the T-Force kit offers a clear advantage with its dedicated compatibility for both major platforms.
ECC Support
Both memory kits include On-die ECC, a feature that self-corrects DRAM cells to maintain data integrity. The TEAMGROUP Elite kit is labeled as Non-ECC in its attributes but specifies On-die ECC in its features, which is standard for consumer DDR5 modules. The TEAMGROUP T-Force Delta RGB also lists On-die ECC support. This means both kits provide the same level of internal error correction for stability. Neither kit offers traditional registered ECC for servers. You get equal data protection from both options, as they rely on the same underlying DDR5 technology for error handling.
Voltage
The TEAMGROUP Elite kit operates at 1.1V. This is the standard voltage for DDR5 memory, ensuring good energy efficiency and heat management. The voltage specification for the TEAMGROUP T-Force Delta RGB is not explicitly listed in the provided data. However, DDR5 modules typically run at 1.1V for base operation, with potential increases during overclocking via XMP or EXPO profiles. Without explicit data for the T-Force, we cannot confirm if it differs. You should assume standard DDR5 voltage behavior for both, but the Elite kit has the confirmed specification.
