Introduction to AH253A 8GB DDR2 SDRAM Memory Kit

The AH253A 8GB DDR2 SDRAM memory kit is a product developed by Hewlett-Packard (HP) for server use. It is specifically designed for use in high-performance computing and data center environments where reliability, speed, and data integrity are paramount. This memory kit is made up of four 2GB DIMMs (dual in-line memory modules), each operating at a speed of 533 MHz.

The kit is also equipped with advanced features such as ECC (error-correcting code) and registered memory, which help to ensure data integrity and prevent memory errors. In this article, we will dive into the details of these features and explain why they are important for server memory.

Single Rank vs. Dual Rank Memory

The AH253A 8GB DDR2 SDRAM memory kit features single rank memory. This means that each memory module has a single set of memory chips on each side, allowing for faster access times and improved data transfer rates. In contrast, dual rank memory has two sets of chips on each side, which can lead to slower performance due to increased wait times for accessing data.

ECC Memory & Registered Memory

ECC (error-correcting code) memory is a type of memory that can detect and correct single-bit errors in data. This is accomplished through the use of additional memory chips that store parity information, which is used to compare against the data stored in the main memory chips. If a single-bit error is detected, the ECC memory can correct it on the fly, without any impact on the performance of the system.

ECC memory is particularly important for server memory, as it can prevent data corruption that can occur due to cosmic rays, thermal events, or other environmental factors. In addition, ECC memory can help prevent system crashes and data loss, which can be especially damaging in mission-critical environments.

Registered memory, also known as buffered memory, is a type of memory that uses an additional buffer chip to isolate the memory controller from the memory chips. This helps to reduce electrical loading on the memory controller, which can lead to improved stability and performance.

In addition, registered memory can also support higher memory densities than unbuffered memory. This is because the buffer chip allows for more memory chips to be connected to the memory controller without overloading it. However, registered memory may also introduce additional latency due to the extra layer of communication between the memory controller and the memory chips.

240-Pin DIMM Form Factor

The AH253A 8GB DDR2 SDRAM memory kit uses a 240-pin DIMM (dual in-line memory module) form factor. This is a standard form factor used in desktop and server memory, and it allows for easy installation and replacement of memory modules.

The 240-pin DIMM form factor is also compatible with DDR2 memory, which was a common memory standard for desktop and server systems during the mid-2000s. DDR2 memory operates at a lower voltage than its predecessor, DDR memory, and it also features higher clock speeds and improved power efficiency.

In summary, the AH253A 8GB DDR2 SDRAM memory kit is a high-performance memory solution designed for use in server environments. It features advanced features such as ECC memory and registered memory, which help to ensure data integrity and prevent memory errors. In addition, the 240-pin DIMM form factor makes installation and replacement easy, while the use of single rank memory allows for improved performance and data transfer rates. If you're looking for a reliable, high-performance memory solution for your server, the AH253A 8GB DDR2 SDRAM memory kit is definitely worth considering.

What does ALLHDD.Com warranty cover?

30-days to 3 years warranty:

Replacement or refund. In the case of material defects, we will try to replace the product first. The product will be replaced before the expiration of the original warranty. For any failure of hardware, if we cannot process the replacement of the product(s)/model(s), we will refund the original selling/invoiced price. The shipping costs and sales tax, if any, are non-refundable. ALLHDD retains the right to decide whether the item(s) will process for replacement or refund.

What is not covered by our warranty?

The reason why our warranty does not cover any problem caused by the following conditions:

(a) misuse of hardware; accidental damage; carelessness product(s) damage; shock; temperature beyond the specification of any product; faulty installation; operation; modification of goods;

(b) any misuse outside the instructions in the user manual for any specific product;

(c) damaged caused by other hardware or equipment. The warranty will void if the item is returned with physical damage, damage to the retail box, removed from the box, counterfeit labels/labelled by them, or any modifications of internal and external covers. Data loss or damages to any other equipment we do not cover by our offered warranty.

What is the Manufacturer/Brand Warranty?

In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).

For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
