In case you want to buy the remanufactured products, you should keep some things in mind. Here are a few tips that can be of help when you want to buy the HP Renew Products;

Buy directly from a certain manufacturer- be sure that the manufacturer is the original manufacturer as brokers may be looking to recoup losses as they may refurbish the products at a low price and they may resell it to unsuspecting customers without them being tested for Stringent HP standards.

Check warranty- make sure that the seller does guarantee you of the product that they are selling to you and they are covered by the original HP warranty. Also, check the software, support as well as the service option in order to make sure that the equipment can be added to your service contract.

Why Choose HP Ram Over Other Manufacturers?

Choosing the right memory configuration for your server or computer goes a long way in ensuring that the server or computer will have a significant impact on application performance. A while back, all you had to do was to specify the memory based on the GB per core however, 

with the introduction of virtualization, the quality as well as the reliability of the RAM is more important than ever. 

Virtualization has a lot of benefits but it increases the amount of memory servers that are required for optimal performance of a virtual machine. The reason why HP Ram is preferable over other manufacturers is the qualification and testing level that the memory undergoes. This is what gives the memory the HP difference. Other manufacturers usually fore-go this crucial process that is required for improving the value of the DRAM modules.

Though you may find some third party modules in the market that are quite cheaper, their performance is most likely to be poor and inconsistent, and they also have higher failure rates when it comes to operating at higher speeds. So buying memory based on price can be very risky. You may end up suffering the true costs of using lower quality memory in the long run which include data loss, system downtime as well as reduced productivity. You should rather pay a little more for HP qualified memory and avoid facing these issues.

HP ram is usually taken through extensive qualification and testing using proprietary diagnostic tools as well as specialized memory diagnostic server tests that are of highest standards to make sure that highest level of performance is achieved. HP also chooses the highest quality DRAM from manufacturers. During this process, the HP Memory Core Team assesses the product design, track record, program plans, past failure rates, technologies as well as manufacturing capabilities of the suppliers. The supplier that is selected is the one that has the highest memory quality product. After that the memory proceeds to the development validation phase.

During the development validation phase, HP verifies that the memory meets quality as well as reliability specifications. This phase requires a solid collaboration between HP and its memory suppliers with the use of HP-developed specifications, procedures as well as test software. The compatibility of the ram is tested with HP memory development engineers using several HP systems that have new and legacy applications. The initial quality and reliability of the memory products is measured to make sure that they conform to HP specifications.

Before the HP ram is released into the market, it undergoes stress tests in every supported HP server. 

The memory is stressed by changing workloads as well as system temperature in order to stimulate the operating environments that are most demanding. The stress tests are done to reduce cases of memory failures. Other manufactures fore-go this level of extensive testing, and as a result they end supplying low quality or defective rams to customers. 

All of these processes that HP ram goes through should give you the confidence that you are buying high quality and reliable memory that will have the least number of interruptions when you are using your computer.

Sata Hard Drive - Some Problems You May Experience

Serial ATA, popularly known as SATA (Advance Technology Attachment), is a computer bus interface linking host bus adapters to devices that are responsible for the storage of large amounts of data like optical drives and hard disk drives. It offers several advantages over the older version interface, for example:

- Reduced cost due to smaller cable sizes
- Using only 7 conductors instead of 40
- Faster transfer of data via higher signal rates
- Native hot swapping
- Increased efficiency in transfer via an I/O queuing protocol (optional)

 However, below are some of the problems you may experience with a SATA hard drive.

At times when you install Windows OS on your computer that has multiple SATA or RAID disks, the disk drive numbers may not correctly correspond to the SATA channel numbers as they should. Some ATA hard drives perform very regular head overloads in Linux which greatly reduces their lifespan. This is because the inactivity timer for head unload is specially configured in an overly aggressive way through ATA APM (Advanced Power Management), a feature that is unfavorable just like other non-standard ways. 

Such aggressive configurations are very sensitive to changes in IO pattern and several drives like these unload their heads and re-load them in a short while under Linux. In Windows, certain vaccine programs that are known to run in the background and can change the IO pattern may also trigger this relentless unloading and re-loading cycle. 

When libata is used with specific TSS Tcorp TS-L623D drives, some obvious hardware issues that may arise include the user experiencing some random system freezes periodically and lasting only a few minutes. After being continuously polled by hald-addon-storage, TS-L623D firmware stops responding. Acer and Asus laptop computers are the major victims.

However, Samsung SC02 seems to remain unaffected by this problem. Some of the suggested solutions to help tackle this problem include keeping a Compact Disk in the TS-L632D drive, killing the hald-addon-storage process, or cross-flashing the TS-L632D drive firmware to the SC03 version.

There are various ways to cross-flash, however, it is a risky process which could be harmful or damaging to the hard disk and as may also void the warranty. Therefore, the user is exclusively warned to use these methods at their own risk. 

First, you may consider downloading the Samsung firmware update utility or the Samsung firmware. Running �sfdnwin -nocheck� is also another option that may be used to cross-flash. (Take note that some Seagate hard drives sold during the late 2008 may time out the FLUSH CACHE when combined with NCQ commands, a problem commonly caused by firmware bug). 

The list of some of the devices affected includes ST31500341AS, ST3640623AS, ST3320813AS, ST31000333AS, ST3640323AS and ST3320613AS models. However, when any of the above mentioned devices are detected to emit a warning message, libata, in that case, will automatically disable NCQ. Some SATA hard drives e.g. hdparm t, may also display poor performance with sequential reads with measurements reaching only between 20-90% of the total expected speed. During software RAID checks and rebuilds, similar performance issues have been noticed.

These varieties of SATA hard disk problems may affect various device models differently depending on particular hard disk model and size. The various solutions available also depend on the type of hard disk problem experienced.
