Hey guys! Today, we're diving deep into the SK Hynix 4GB 1Rx16 PC4-3200AA-UC011 RAM module. If you're looking to upgrade your system's memory or just curious about what this little guy can do, you've come to the right place. We'll break down its specifications, performance, and everything else you need to know. So, let's get started!

Understanding the Basics of SK Hynix 4GB RAM

Let's start with the basics. The SK Hynix 4GB 1Rx16 PC4-3200AA-UC011 is a DDR4 (Double Data Rate 4th generation) SDRAM (Synchronous Dynamic Random-Access Memory) module. This means it's designed for modern desktops and laptops that support DDR4 memory. The "4GB" indicates the module's capacity, which is the amount of data it can hold. In today's world, 4GB might seem small, especially with demanding applications and games, but it can still be useful for basic computing tasks or as part of a multi-module setup.

The "1Rx16" refers to the module's rank and organization. "1R" means it's a single-rank module. A rank is a set of memory chips that can be accessed simultaneously, forming a 64-bit wide data channel (72-bit for ECC memory). "x16" indicates that each chip on the module has a 16-bit wide data interface. Single-rank modules are generally easier on the memory controller and can be a good choice for systems where compatibility is a primary concern.

"PC4-3200" specifies the module's speed. Here, PC4 stands for DDR4, and 3200 refers to the data transfer rate in megatransfers per second (MT/s). This means the module can transfer data at a rate of 3200 million times per second. To convert this to bandwidth, you multiply the data transfer rate by 8 (since each transfer involves 8 bits, or 1 byte). So, 3200 MT/s translates to a bandwidth of 25.6 GB/s (3200 x 8 = 25600 MB/s or 25.6 GB/s). This is a crucial factor in determining how quickly your system can access and process data.

Finally, "AA-UC011" is a specific identifier for this particular model, which can indicate the manufacturing batch, specific timings, or other details relevant to the manufacturer. It's useful for identifying the exact specifications and ensuring compatibility when purchasing additional modules.

Key Features and Specifications

• Capacity: 4GB
• Type: DDR4 SDRAM
• Rank: 1Rx16 (Single Rank)
• Speed: PC4-3200 (3200 MT/s)
• Bandwidth: 25.6 GB/s
• Module Type: SODIMM or UDIMM (depending on the application – typically UDIMM for desktops, SODIMM for laptops)
• CAS Latency (CL): This is a crucial timing parameter that indicates the delay between when the memory controller requests data and when the memory module provides it. The lower the CAS latency, the faster the memory. For this module, the typical CAS Latency is around CL22. For example, you might see it specified as 22-22-22. This represents the timings for CAS Latency (CL), Row Address to Column Address Delay (tRCD), and Row Precharge Time (tRP).
• Voltage: 1.2V (DDR4 standard low voltage)
• Error Correction: Non-ECC (Error-Correcting Code). This means the memory does not have error-checking capabilities, which is typical for consumer-grade memory.

Performance Analysis

When we talk about performance, it's not just about the numbers on the specification sheet. Real-world performance depends on how well the memory module integrates with the rest of your system. Let's break down the key factors:

Speed and Bandwidth

The PC4-3200 speed rating means this module is capable of handling a large volume of data quickly. With a bandwidth of 25.6 GB/s, it ensures that your CPU and other components have rapid access to the data stored in the memory. This is particularly important for tasks like video editing, gaming, and running multiple applications simultaneously. The faster the memory, the less likely it is to become a bottleneck in your system's performance.

CAS Latency (CL)

The CAS Latency (CL) is a critical factor in determining memory performance. A lower CL value means the memory can respond more quickly to data requests. The SK Hynix module typically has a CL of around 22. While this isn't the lowest latency available on the market, it's fairly standard for DDR4 memory. Keep in mind that lower latency modules often come at a higher price, so it's a trade-off between performance and cost.

Single vs. Dual Channel

To maximize the performance of your memory, consider running it in a dual-channel configuration. This involves installing two identical memory modules in the appropriate slots on your motherboard. Dual-channel mode effectively doubles the memory bandwidth, which can significantly improve performance, especially in memory-intensive applications. If you're using a single 4GB module, adding another identical module can provide a noticeable boost in performance.

Real-World Benchmarks

In real-world scenarios, the performance of the SK Hynix 4GB module can be evaluated through various benchmarks. For example, in gaming, a faster memory module can lead to higher frame rates and smoother gameplay. In video editing, it can reduce rendering times and improve the responsiveness of editing software. Similarly, in everyday tasks like web browsing and document editing, faster memory can make your system feel more responsive.

Tools like AIDA64 and Memtest86 can be used to measure the memory's bandwidth, latency, and stability. These benchmarks provide valuable insights into how the memory performs under different workloads.

Compatibility

Ensuring compatibility is crucial when upgrading or adding memory to your system. The SK Hynix 4GB 1Rx16 PC4-3200AA-UC011 module is designed to be compatible with a wide range of desktops and laptops that support DDR4 memory. However, there are a few factors to consider:

• Motherboard Support: Check your motherboard's specifications to ensure it supports DDR4 memory and the specific speed (3200 MT/s) of the module. Most modern motherboards that support DDR4 will be compatible, but it's always a good idea to double-check.
• Form Factor: Determine whether you need a UDIMM (Unbuffered DIMM) for desktops or a SODIMM (Small Outline DIMM) for laptops. The SK Hynix module is available in both form factors, so make sure you choose the right one for your system.
• BIOS Settings: In some cases, you may need to adjust the BIOS settings to ensure the memory is running at its rated speed. This involves enabling the XMP (Extreme Memory Profile) or manually setting the memory speed and timings.
• Maximum Memory Capacity: Check the maximum memory capacity supported by your motherboard. While a single 4GB module may be compatible, you need to ensure that your system can support the total amount of memory if you plan to add more modules in the future.

Pros and Cons

Pros:

• Compatibility: DDR4 is widely supported on modern systems.
• Speed: 3200 MT/s provides good performance for everyday tasks and some gaming.
