I would buy RAM from one of these three companys:
(just plug in your specs, they'll give you options)CrucialKingstonCorsair
These are reputable companys that stand behind their products. Also, check out the info on
their sites. There's a lot of good info about RAM, definitely worth the read.
Some additional info on RAM:
There are such things as cheap , ninety day , or generic RAM, which is actually sold,
and doesn't meet the minimum standards of the JEDEC
(Joint Electron Device Engineering Council), for use in computers. But it is still sold, and un-informed people, still buy it.
RAM can generally be divided into a few classes:
(Excepting Performance or Overclockers RAM, which is made to the highest tolerances)Premium or Lifetime Warranty
: This RAM is made from Identical chips, all tested
and meeting the assemblers standards, all from the same chip manufacturer and lot.
The capacitors and resistors are of the highest standard, and exceed the JEDEC
standard, and all are installed on a circuit board which is thicker than required . The
final product is tested to confirm that it is stable at the rated speed.One Year Warranty
: Very close, but may include memory chips from different batches,
although still the same manufacturer. The circuit board tends to be at least one ply
thinner, and the resistors and capacitors may have more variance. These still meet the
JEDEC standards, and are tested to make sure they are stable at the specified speed.OEM
: These are intended for sale to a manufacturer, not for resale, although they
often are sold retail. Often if you buy two sticks, you will find that they have memory
chips from different manufacturers. They still meet standards (the chips are certified to
meet the manufacturers specifications), but are often yet another ply thinner, and once
again, may have more variance in the tolerance of resistors and capacitors, and may
use fewer, than on higher quality RAM.Generic or 90 Day RAM
: This is the lowest quality you will generally encounter.
Often these are made of leftover chips; ones salvaged from returned and failed RAM,
RAM designed to run at a higher speed which failed and became unstable. They are
put on really thin boards, which do not meet the JEDEC standard. They rarely have
even the minimum number, and quality of resistors and capacitors, recomended by the
Also, if you touch the RAM anywhere except the edges, you should know that the oils
and salts in your skin are corrosive, and will eventually damage the ram. And if you
touch it without observing anti-static precautions, you can cause damage, which may
show up immediately, or somewhere down the line.
This is why I always recommend that you spend the extra money to buy Quality Name
with a lifetime warranty. I also prefer to buy all RAM at one time when
possible, and at a minimum, make sure it has identical specifications (easiest method,
make sure it is same manufacturer and model).
