About Hardware DDR3 SODIMM 1066MHz [Disk]

DDR3 SODIMM 1066MHz is a third-generation memory module with a speed of 1066MHz that is commonly used in laptops and small devices. With the SODIMM form factor, these modules are often the standard choice for mobile computing systems, serving as the main memory for running operating systems, applications, and light to medium multitasking processes.

However, in this particular experiment, two 1066MHz DDR3 SODIMM modules from Micron and ADATA (2GB capacity each) were uniquely configured as a RAMDisk, a temporary storage space that uses RAM capacity to simulate a storage drive with much higher access speeds than SSDs or HDDs.

The 1066MHz DDR3 SODIMM-based RAMDisk test was conducted on an HP 1000 1b05au laptop device, powered by an AMD E1-1200 processor. The system is equipped with a 2x2GB DDR3 SODIMM 1600MHz RAM configuration, but due to processor architecture limitations, the memory only runs in single channel mode with an effective speed of 1066MHz. The operating system used is Windows 7, and to create and manage the RAMDisk, two popular applications, SoftPerfect RAMDisk and ImDisk Virtual Disk Driver, were used. The configured RAMDisk size was 2GB, utilizing some of the available RAM capacity.

Even though the device specifications are old and have limited memory bandwidth, the RAMDisk configured in this system was still able to show excellent performance in the read and write speed benchmarks. Based on tests using CrystalDiskMark, the read speed reached 746.24 MB/s, while the write speed touched 828.18 MB/s. In a follow-up test using ATTO Disk Benchmark with a 64MB block size, the read speed increased to 1020.00 MB/s, and the write speed reached 1080.00 MB/s. These results prove that even on older systems, RAMDisk configurations are still capable of delivering very high I/O performance, far surpassing conventional storage such as HDDs or even some SSDs.

Analysis

The results show that a 1066MHz DDR3-based RAMDisk is still capable of delivering data transfer speeds on par with entry-level NVMe SSDs, even outperforming many SATA SSDs and leaving conventional HDDs far behind. This makes RAMDisks an ideal solution for temporary use such as:

• Application caching,
• Temporary file storage,
• Fast computing with high I/O,
• Software or script testing without the risk of contaminating the main file system.

Although limited to a small capacity (2GB in this test), RAMDisk is still very useful for specific needs, especially for users with more than enough RAM or older devices that want to maximize their performance.

Test on:

Device: HP 1000 1b05au
Specs: 
CPU: AMD E1-1200
OS: Windows 7
RAM: 2x2GB Single Channel 2 DIMM 1066MHz (Does not support dual channel due to limitations of the CPU, currently running single channel mode and 1066MHz)

About Hardware AMD Radeon HD 7310 IGPU VRAM Disk

The AMD Radeon HD 7310 is an integrated GPU (iGPU) based on the Terascale 2 architecture embedded in some early generation E1 series APUs, such as the AMD E1-1200. With 80 Stream Processors, this GPU is designed for light tasks such as video playback, basic computing, and casual gaming with low graphics settings. Despite being an entry-level GPU and being quite old, the Radeon HD 7310 is still able to operate well for basic needs and certain technical experiments.

In this test using an HP 1000 1b05au device paired with an AMD E1-1200 processor, 4GB DDR3 RAM, and Windows 7 operating system, an interesting experiment was conducted by converting part of the VRAM allocation into a VRAMDisk using specialized GPU RAM Drive software.

VRAMDisk is a method that utilizes VRAM capacity as high-speed temporary storage, just like RAMDisk but with graphics memory. In this configuration, of the total VRAM of 384MB (plus shared memory), about 128MB was set aside to be used as a VRAMDisk. Despite the small capacity, the read and write speeds were quite surprising:

• CrystalDiskMark:
  • Read: 393.23 MB/s
  • Write: 393.66 MB/s

This figure shows that even using an older generation GPU with DDR3 memory and a 128-bit interface, the VRAM still has enough bandwidth for light cache tasks or fast storage experiments. This technology is not intended for daily use, but it can be an interesting alternative for technical purposes, testing, or short-term local access speeds of small files.

Given its limitations-both in terms of VRAM capacity, iGPU performance, and modern driver support-the AMD Radeon HD 7310 is definitely not an option for gaming or heavy workloads right now. However, experiments like this VRAMDisk show that legacy devices can still be creatively utilized in certain contexts, especially in resource-constrained environments.
