Crucial CT2K16G56C46U5 DDR5-5600 2x16GB Review (Page 2 of 10)

Page 2 - A Closer Look, Test System

As we have noted previously, Crucial has been producing only OEM-grade memory, as its previous Ballistix branding ceased to exist. This set of memory is part of their newest launch of their DDR5 lineup with increased transfer rates of DDR5-5600. There is also a DDR5-5200 version. While it is strange to see no heatspreader on top, one primary advantage of this is compatibility, as these are guaranteed to be compatible with CPU coolers of all shapes and sizes. It should not reach any dangerous levels of warmth for you to be concerned about, as this set of memory operates at a low voltage of 1.1V. In reality, the heatspreader adds only a visual appeal, especially for those with windowed cases. Thankfully, the black PCB makes this kit fit into practically any build, especially if you are not going for an RGB LED build.

From the photo above, you can see the two sticks of Crucial CT2K16G56C46U5 DDR5-5600 2x16GB with a black PCB. The power management integrated circuit, also known as a PMIC, is in the middle of each module. Four memory chips can be found to the left and right of the PMIC. A specifications label covers the right side and lists the model number, bandwidth, CAS latency, voltage, and DIMM's memory capacity. Both of these modules are made in Malaysia.

With a closer look at the surface components, we have two primary things to look at. First is the PMIC, which is labeled with P8911Y0. This is a Renesas P8911 power management IC. Next, we have a closer look at one of the eight memory chips. These are Micron-manufactured with a "D8DDZ" FBGA inscription on each IC. Its full part number is MT60B2G8HB-56B:G, and these are 2GB chips for a total of 16GB on each DIMM. As mentioned on the previous page, the RAM modules run at speeds of DDR5-5600 with 46-45-45-90 latencies. They operate at the base DDR5 voltage of 1.1V, which is well under the maximum safe limit of 1.35V defined by both Intel and AMD. Below are the listed features for the ICs from Micron's website:

• VDD = VDDQ = 1.1V (NOM)
• VPP= 1.8V (NOM)
• On-die, internal, adjustable VREF generation for DQ, CA, CS
• 1.1V pseudo open-drain I/O
• TC maximum up to 95°C
– 32ms, 8192-cycle refresh up to 85°C
– 16ms, 8192-cycle refresh at >85°C to 95°C
• 32 internal banks (x4, x8): 8 groups of 4 banks each
• 16 internal banks (x16): 4 groups of 4 banks each
• 16n-bit prefetch architecture
• 1 cycle/2 cycle command structure
• 2N mode
• All bank and same bank refresh
• Multi-purpose command (MPC)
• CS/CA training mode
• On-die ECC (bounded fault)
• ECC transparency and error scrub
• Decision feedback equalization (DFE)
• Loopback mode
• Command-based non-target (NT) nominal, DQ/DQS park, and dynamic WR on-die termination (ODT)
• sPPR and hPPR capability
• Per-DRAM addressability
• JEDEC JESD-79.5 compliant
