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.


No matter if you want to improve the virtualization of your workstation or upgrade your business center's servers, a memory upgrade is a must! Another way round, the bulky files and ballooning up of the data may cause the servers to slow down the overall transfer rates and performance. Thus, a significant upgrade that makes the impeccable difference in boosting the overall PC's performance and improving the virtualization is the addition of memory. There are plenty of more reasons why you need to opt for the PC2 4200 RAM for your system. Here's why!

No More Slow Calls!

Whenever there is a need for data transfer and direct access from the hard drive, the RAM module plays a vital role. There will be no fighting over hard drive access, especially in virtual networking, as the data banks can be easily reached via the DDR2 RAM. However, in virtualization and large server rooms, you can allocate a separate DDR2 DIMMS to each machine, and the same hard drive will be accessed/shared with a higher pace performance.

DDR2 SDRAMs Ensures The Integrity:

PC2-4200 is a DDR2 SDRAM that ensures signal integrity and overall data encryption. Most of the memory devices featured at ALLHDD, including the 8GB, 16GB, and 32GB, are all ECC certified, equipped with a unique algorithm to check for the data's errors and mistakes. There are multiple other benefits of owning these PC2 4200 RAM, and here's why you need to keep your hands on these!

PC2-4200 DDR2 has the PCB Layout:

There should be no lags and flaws while accessing the data from the hard drive. Thus, to ensure this, the PC2-4200 RAM contains the PCB layout and the 240 pin slots that would be a winning combination for the signal integrity.

Uni-Directional Signals are the key!

DDR2 SDRAMs have the PCB layout and the transmission lines on the circuits designed for the higher frequencies. Thus, the command signals running through the circuits are all uni-directional and terminate on the circuit board, enabling the simple terminating techniques.

Supports the On-Die Termination:

PC-4200 RAM modules are equipped with support for the on-die termination. The memory controller hub controls the ODT, which smoothens the line termination process. This way, the memory modules DDR2 533 Mhz can better handle the signal integrity, voltage performance, and slew rate. Overall, the performance is carried out at a higher pace, reducing the data loss.

Improved Memory Data Throughput:

It has a direct connection with the latency! The PC-4200 DDR2 SDRAMs are equipped with the additive latency option to improve the sending, reading, and writing data speed.
