We found that the Corsair Vengeance LPX 3200 MHz DDR4 RAM has a clock speed of 3200 MHz and a latency of 10 ns (16-20-20-38 timings), allowing it to provide quick and efficient performance. We determined that this DDR4 RAM balances speed and latency, making it ideal for users who want excellent performance at a reasonable price compared to newer DDR5 RAM. We saw that it is suitable for demanding tasks that require speedy data processing.
We feel that the Corsair Vengeance LPX 3200 MHz DDR4 RAM is an excellent addition to any value gaming rig or workstation, especially when paired with the AMD Ryzen 3 3100 CPU. Its voltage of 1.35 volts is around average for most DDR4 RAM. We saw that the high-quality aluminum heatsinks provide superior thermal management while giving the modules a sleek and premium appearance, and they do not interfere with the CPU cooler. Moreover, the RAM is optimized for AMD DDR4 motherboards, ensuring a smooth and dependable experience for users who want the best performance from their AMD processors.
We determined that the only drawback of this RAM is that it is DDR4 instead of the newer and faster DDR5 RAM, but it is significantly less expensive than DDR5. However, the Ryzen 3 3100 only supports DDR4, so this 'drawback' is irrelevant for those who want or already have this CPU.

Memory Generation Supported by the 3100
The Ryzen 3 3100 CPU only supports DDR4 memory. Other generations of memory are incompatible.
The generation of memory (e.g., DDR3, DDR4, or DDR5) must match what is supported by your motherboard. Motherboards only support a single generation of memory.
To learn more about the difference between DDR5 and DDR4, check out our article: DDR4 vs. DDR5? Which You Should Buy.
Maximum Memory Speeds Supported by the 3100
The maximum speed at which you can run PC memory depends on your CPU, motherboard, and the memory itself.
When using DDR4 memory, the Ryzen 3 3100 CPU officially supports effective memory speeds up to 3200 MHz (3200 MT/s). This maximum speed means that stock DDR4 performance will be maximized using DDR4-3200 memory.
When overclocking memory, you can exceed these stock speeds officially supported by CPUs. We've found that motherboard specifications will indicate their supported overclocked-memory speeds.
RAM can also be underclocked to achieve compatibility, which we found is a great option to try in some cases. Underclocking can be used when you purchase memory that is faster than the maximum speed supported by the CPU or motherboard. However, precise underclocking also requires a motherboard that supports memory overclocking. Without this support, we've seen that memory may fall back to a slower speed than the maximum supported memory speed. To achieve the maximum memory speed without overclocking support, use the maximum speed supported by the motherboard and CPU.
By looking up a motherboard's specifications, you can verify whether it supports a particular speed. Additionally, we've found that the motherboard manufacturer's website will typically indicate which memory kits have been confirmed to be compatible.
Compare DDR4 speeds to the previous generation DDR3 speeds in the following table:
|Max UDIMM (Unbuffered) Capacity||16 GB||32 GB|
|Bandwidth||6400–17067 MB/s||12800–25600 MB/s|
|Transfer Rate||800–2133 MT/s||1600–3200 MT/s|
|Base Frequency||400–1067 MHz||800–1600 MHz|
|Effective Frequency||800–2133 MHz||1600–3200 MHz|
|Voltage||1.5 V||1.2 V|
3100 ECC Memory Support
We have seen that most gaming and general-purpose desktop setups do not use ECC memory.
Error correction code (ECC) memory is a more expensive form of memory typically used for critical server and workstation use cases. The purpose of ECC memory is to detect and correct when a single bit in memory gets flipped unintentionally.
ECC memory will not work unless the motherboard and CPU support ECC.
AMD unofficially supports ECC memory in most Ryzen CPUs. Unofficial support basically means it is not validated to work but should work in most cases.
One Ryzen processor category which doesn't work with ECC memory is the non-"Pro" APU. The 3100 does not have "Pro" in the name but is not an APU (it doesn't have integrated graphics), so it does not fall into this category.
The primary requirement for using unbuffered ECC memory with Ryzen CPUs that support ECC memory is that it must be used with a motherboard that supports such memory in ECC operation mode.
When desktop motherboards support ECC memory, it's typically limited to "unbuffered ECC" memory. Server motherboards may support "registered ECC" memory, which allows for additional memory modules.
Before Buying RAM
Before purchasing memory, we suggest that you review your motherboard specification to verify which speeds are supported. For example, if a DDR4 motherboard stated that it supports "DDR4 3400(O.C.) / 3333(O.C.) / 3300(O.C.) / 3200 / 3000," that would mean that it could support DDR4-3400, DDR4-3333, and DDR4-3300 with memory overclocking, and DDR4-3200 and DDR4-3000 at stock speeds. We have seen that motherboard specifications also indicate the maximum capacity per stick of RAM (DIMM) and across all slots.
