Product Overview of IBM 49Y1449 8GB DDR3 Memory
The IBM 49Y1449 is an 8GB DDR3 memory module designed for use in server systems. It is a registered ECC memory module that operates at a frequency of 1333MHz with a CL9 latency. This module is also designed as a dual-rank memory module with a voltage rating of 1.5v. The module has a 240-pin RDIMM form factor, which makes it compatible with a wide range of server systems that support DDR3 memory. In this article, we will take a closer look at the features and specifications of the IBM 49Y1449 memory module.
DDR3 Memory Technology
DDR3 (Double Data Rate 3) is a type of synchronous dynamic random-access memory (SDRAM) that is widely used in modern computer systems. It is the successor to DDR2 memory and offers several performance improvements, including higher data transfer rates, lower power consumption, and increased memory capacity. DDR3 memory modules use a clock speed of 800MHz to 2133MHz, with data rates of up to 17GB/s.
ECC Memory
Error-correcting code (ECC) memory is a type of memory that can detect and correct certain types of memory errors. This type of memory is commonly used in server systems, where data integrity is critical. ECC memory works by adding additional parity bits to each memory module, which are used to check for and correct errors in data transmission. The use of ECC memory can help to prevent data corruption and improve system stability.
Registered Memory
Registered memory, also known as buffered memory, is a type of memory that includes an additional buffer chip on the module. This buffer chip acts as an intermediary between the memory controller and the memory chips, helping to reduce the electrical load on the memory controller. Registered memory is commonly used in server systems, where large amounts of memory are required, and system stability is critical.
Dual-Rank Memory
A memory rank is a set of memory chips that are accessed together as a single group. Dual-rank memory modules have two sets of memory chips that are accessed independently, allowing for improved performance in certain applications. Dual-rank memory modules also offer better memory density, allowing for higher memory capacity per module.
CL9 Latency
Latency is the amount of time it takes for data to be transferred between the memory module and the processor. CAS latency (CL) is a measure of memory latency, representing the number of clock cycles between the processor sending a request for data and the data being available to the processor. A lower CL latency indicates faster memory access times. The IBM 49Y1449 memory module has a CL9 latency, which is a relatively low latency compared to other DDR3 memory modules.
240-pin RDIMM Form Factor
The IBM 49Y1449 memory module has a 240-pin RDIMM (Registered Dual Inline Memory Module) form factor. This type of memory module is commonly used in server systems and provides improved memory density compared to other form factors. RDIMMs also include an additional buffer chip, which helps to reduce the electrical load on the memory controller.
Summary, the IBM 49Y1449 8GB DDR3 memory module is a high-performance memory module designed for use in server systems. It features a range of advanced technologies, including ECC memory, registered memory, and dual-rank memory, which make it suitable for use in high-performance server applications. The module has a CL9 latency, which is relatively low for a DDR3 memory module, and a 240-pin RDIMM form factor, which makes it compatible with a wide range of server systems. Overall, the IBM 49Y1449 is a high-quality memory module that provides

About New Bulk Pack Products
Warranty
ALLHDD guarantees that the products will not have defects in material that will affect the product's functionality during the Standard Warranty Period. The warranty period starts when the merchandise/items from our warehouse.
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.
