Product Details

HMT31GR7BFR4C-H9 is a memory module made by Hynix, a South Korean semiconductor company. It is an 8GB DDR3 SDRAM memory module designed specifically for use in servers. In this article, we will discuss the features and specifications of the HMT31GR7BFR4C-H9 memory module in detail.


DDR3 SDRAM stands for Double Data Rate 3 Synchronous Dynamic Random-Access Memory. DDR3 SDRAM is a type of volatile memory that stores data temporarily and requires a constant power supply to retain the stored information. DDR3 SDRAM operates at higher frequencies and lower voltages than its predecessor, DDR2 SDRAM. It is currently the most common type of memory used in personal computers and servers.

ECC Registered Dual Rank X4

The HMT31GR7BFR4C-H9 memory module is an ECC Registered Dual Rank X4 module. ECC stands for Error-Correcting Code. ECC memory modules use an algorithm to detect and correct errors that occur during data transmission. This is particularly important in servers, where data integrity is crucial. Registered memory, also known as buffered memory, uses a buffer to improve signal integrity and reduce electrical loading. Dual rank memory modules have two sets of memory chips on each side of the module. X4 refers to the fact that each chip has 4 bits of data lines. All of these features contribute to the module's stability and reliability.

PC3-10600 1333MHz

PC3-10600 is the technical name for DDR3 memory that operates at 1333MHz. The number 10600 refers to the module's bandwidth in megabytes per second (MB/s), which is calculated by multiplying the frequency (1333MHz) by the number of bits transferred per clock cycle (64). Therefore, the module's bandwidth is 10666MB/s, which is also referred to as PC3-10600. The higher the bandwidth, the faster the memory can transfer data.


CL9 stands for CAS Latency 9. CAS Latency is the delay between the time the memory controller requests data from the memory module and the time the data is available. The lower the CAS Latency, the faster the memory can respond to requests. CL9 is a relatively low CAS Latency, which contributes to the module's speed.


The HMT31GR7BFR4C-H9 memory module operates at 1.5 volts. This is the standard voltage for DDR3 memory modules. Operating at a lower voltage reduces the module's power consumption and heat generation, which is particularly important in servers, where energy efficiency and cooling are critical.

240-Pin DIMM

The HMT31GR7BFR4C-H9 memory module has 240 pins and uses a Dual In-line Memory Module (DIMM) form factor. DIMMs are the most common type of memory module used in servers and personal computers. The number of pins on a DIMM determines the module's bandwidth and capacity. 240-pin DIMMs are typically used in servers and high-end workstations.

In summary, the HMT31GR7BFR4C-H9 memory module is an 8GB DDR3 SDRAM memory module designed for use in servers. It operates at 1333MHz, has a CAS Latency of 9, and uses ECC Registered Dual Rank X4 technology. The module operates at 1.5 volts and uses a 240-pin DIMM form factor.

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.


Please choose your location for calculate shipping cost.


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.
