Crucial CT2K16G48C40U5 DDR5-4800 2x16GB Review (Page 2 of 10)

Page 2 - A Closer Look, Test System

After Crucial discontinued their Ballistix brand, the company reverted to selling OEM-grade memory only. The Crucial CT2K16G48C40U5 DDR5-4800 2x16GB, being a part of the latest consumer DDR5 line from the company, has no heatspreaders at all. Therefore, it is guaranteed to be compatible with CPU coolers of all shapes and sizes. If you are concerned about heat issues due to the lack of heatspreaders, there simply is nothing to worry about. For pretty much all memory modules, unless run at a voltage significantly over designed voltages -- which you will not, special thanks to integrated memory controller voltage limits on Intel and AMD CPUs -- heatspreaders are not a requirement. All you are missing out on are purely cosmetic when placed in a windowed chassis.

As you can see in my photo above, the Crucial CT2K16G48C40U5 DDR5-4800 2x16GB has a very nice black PCB. We can also spot the power management integrated circuit, commonly abbreviated as PMIC, near the center. A specification label is found on one side of both DDR5 memory modules. It lists the CT2K16G48C40U5 model number, bandwidth, CAS latency, voltage, and the DIMM's memory capacity. The Crucial CT2K16G48C40U5 DDR5-4800 2x16GB is made in Malaysia, hence why it was shipped to us from there directly.

A closer look at the memory chips on the Crucial CT2K16G48C40U5 DDR5-4800 2x16GB dual channel memory kit. The photo above should be quite clear -- it says "D8BNJ" on each IC. These are Micron-manufactured chips identified as MT60B2G8HB-48B:A decoded from the FBGA inscription, with four 2GB chips on each side for a total of 16GB on each DIMM. As mentioned on the previous page, these RAM modules run at a frequency of DDR5-4800 with 40-39-39-77 latencies. They operate at the base DDR5 voltage of 1.1V and under the maximum safe limit of 1.35V defined by both Intel and AMD. Here are the listed features for the ICs, as obtained from Micron's website:

• VDD = VDDQ = 1.1V (nom)
• VPP= 1.8V (nom)
• On-die, internal, adjustable V REF 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
• 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
• JEDEC JESD-79.5 compliant
