Top 6 4 GB Server RAM Units

Like if this guide is helpful
Of course, with all the data a server must handle, it requires plenty of memory. Adding Random Access Memory (RAM) units to a server can speed it up, help it to run more efficiently, and can save energy and wear on other server components. It makes a measurable difference in how the server performs. When shopping for 4 GB server RAM units, consider these top 6, and do not forget to also pick up any accessories that may go with it.
1 HP DDR2 SDRAM ECC Registered RAM Units

The Mushkin Enhanced Proline DDR3 SDRAM ECC registered RAM units are fast, with a CAS Latency of 9 nanoseconds. They are also ROHS and JEDEC compliant, so they are safer for the outside environment and the one inside the server. These are reliable and affordable RAM units and users report that they perform well.

 
 

4 Wintec DDR2 FB-DIMM ECC Fully Buffered RAM Units
Wintec DDR2 FB-DIMM ECC Fully Buffered RAM Units

The Wintec DDR2 FB-DIMM ECC fully buffered RAM units use FB-DIMM memory technology that allows the RAM to process data more efficiently, relieving some of the drain that typically wears on other server components. That, combined with its Advanced Memory Buffer technology, allows the Wintec unit to operate with a CAS Latency of a mere 5 nanoseconds, making it one of the fastest on the list. While this RAM includes an attached heat spreader to help cool it, many reviewers still report the unit can tend to run hot, so be sure that there is adequate airflow and cooling.

 
 

5 Crucial DDR2 FB-DIMM ECC Fully Buffered

The Crucial DDR2 FB-DIMM ECC fully buffered units are fast, with a CAS Latency of 5 nanoseconds. It uses the same fully buffered memory that makes the Wintec so fast. It is worth noting that these FB-DIMM RAM units do not fit in the same slot as a standard DDR2 unit does, so it is important to check for compatibility before purchasing. Crucial designed this unit specifically for faster processors. This RAM also runs very hot, even though it has a built in heat spreader. Be sure to consider that when shopping for the RAM and determining how and where to place it in the server so that it does not overheat.

 
 

6 Kingston DDR2 400 SDRAM ECC Registered RAM Units

When it comes to speed, with a CAS Latency of 3 nanoseconds, the Kingston DDR2 400 SDRAM ECC registered RAM units clearly outranks the other units in the line-up. These units a JEDEC compliant and are energy efficient, draining less power while operating than other RAM units. These do not have a reputation for heating up the way some of the others do, but the manufacturer does recommend installing a heat spreader with the unit.

 
 

Accessories for Server Memory

An important thing to keep in mind about some RAM units is that they can tend to run a little hot. A heat spreader absorbs the heat from the RAM unit and dissipates it, cooling the unit in the process. Some RAM come with heat spreaders built into them. For those that need it and do not come with it, they are available for purchase. On a server, the RAM is not the only item that needs protection from overheating. There are a variety of different fans which fit into specialised locations on the server, blowing air to cool the components. There are even specially designed fans for the RAM.

How to Buy 4GB Server RAM Units on eBay

Servers need RAM to process information efficiently. Adding RAM to a server can increase its performance and seeds. When shopping for 4GB Server RAM on eBay, the main thing to keep in mind is making sure that the RAM is actually compatible with the server. Most servers only accept certain RAM units. The best thing to do is research the specific server's requirements before shopping. With this information in mind, it is easy to find a large selection of RAM units on eBay by using the search tool found on every page.
