but need help with the specific model and amount (at least 8 GB due to
VirtualBox/VM usage).


Check the customer reviews on Newegg, for each product you are
interested in.

Some RAM has a high enough failure rate, you should stay away
from it.

The customer reviews, tells you what to avoid.

Well I wouldn't go solely by some customer reviews. RAM by all the major
suppliers (Crucial, Corsair, etc) is all good. Better to use RAM from the
approved list suggested by the board maker Asus.

Thanks, the customer reviews led me to the following ...

G.SKILL Ripjaws Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3
12800) Desktop Memory Model
F3-12800CL9Q-16GBRL [$95]
http://www.newegg.com/Product/Produc...82E16820231315

G.SKILL Ripjaws X Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3
12800) Desktop Memory Model F3-12800CL9Q-16GBXL [$95]
http://www.newegg.com/Product/Produc...82E16820231429

But, they are not listed in the approved list suggested by the board maker
Asus.
Are these models okay or not?

What is the difference between the two models above?
And, how is G.SKILL vs Crucial vs Corsair?

F3-12800CL9Q-16GBXL "XMP for Intel capable"

F3-12800CL9Q-16GBRL (looks to be the same, only the tested motherboard list,
as tested by them, looks older...)

http://www.gskill.com/products.php?index=335

Note that the modules are pretty tall, and you should check there
is sufficient clearance underneath the CPU cooler. When modules get
tall, sometimes the modules can't be pulled out of the motherboard,
while a third party CPU cooler is installed. (This might not matter
if installing just two sticks, but with four sticks, all slots
are likely to be occupied, and then clearance might be a
"convenience issue".)

The Newegg marketing material mentions AMD compatibility, whereas
the Gskill web page is pushing the XMP tables in the SPD on the DIMM
as the desirable feature.

You tell by the Newegg reviews, whether they know how to make
modules or not. The "79% with 5 stars" reviews, tells you
something.

These Crucial modules, got "83% with 5 starts", but not nearly
as many people bought them. And these have "flashing LEDS" :-)

http://www.newegg.com/Product/Produc...82E16820148519

These Corsair modules, got "83% with 5 stars" on a fairly large
sample size.

http://www.newegg.com/Product/Produc...82E16820145345

"Cons: Failed 2 weeks after putting into a new build."

"Faulty Ram in under a year"

"After 1 week, one of the sticks died"

I'd probably scroll down, and see how common that was.

*******

They call this an "arbitrary judgment system" for a reason :-)

The trick is to detect "signal from noise".

Thanks (Guru Paul), I will likely go with the first one on your list ...

F3-12800CL9Q-16GBXL "XMP for Intel capable"

after checking for height/space clearance at Fry's (or Microcenter).

Corsair, G.Skill, Geil, Patriot, Mushkin, OCZ, Kingston are nothing
special. Most of those companies (actually probably all but one of
them) don't even test their products extensively but simply use PC-
based testers, rather than the million-dollar machines that chip
manufacturers use. One of those module companies even said it was OK
for a module to show 2 errors during testing (except for their 2133
MHz/PC17000 modules, which had to show 0 errors).

Crucial is always good as long as you avoid anything with heatsinks on
it. Another brand that's always good is Samsung, and their 1.35V DDR3
modules will work in 1.5V motherboards.

In general you should avoid any memory with heatsinks on it because
they don't help at all and are actually a sign of low quality -- the
manufacturer can hide no-name or overclocked chips under the
heatsinks, and it's cheaper to slap on highly decorated heatsinks than
to use better quality or faster chips. Also before buying modules
with tall heatsinks, check the clearance between the DIMMs and the CPU
heatsink.

That's not to say everything without heatsinks is high quality. It's
necessary to check the individual chips, and you want chips where the
chip maker or their part number is clearly visible. Chip makers
include Samsung/SEC, Elpida/RexChip, ProMOS, Hynix, Micron, Nanya/
Inotera, and PowerChip.

As for RipJaws specifically, APHnetworks reviewed a PC17000 model
(2133 MHz) and found it was made with Hynix H5TQ2G83BFR-H9C chips.
"H9C" means 1333 MHz:

http://aphnetworks.com/reviews/g_ski...8gbxld_2x4gb/2

I don't think G.Skill is worse in this respect than the vast majority
of its competitors, but the use of overclocked chips could explain why
plain-looking, no-heatsink Samsung PC12800 modules (1600 MHz) are so
well known for being able to run faster than many heatsinked modules
that are "rated" for 2133 MHz.
