That would sell like hotcakes regardless of the price.

SHOCK
NOTE: Tailoring is essential. Select methods, procedures, and parameter levels based on the tailoring process
described in Part One, paragraph 4, and Appendix C. Apply the general guidelines for laboratory test methods
described in Part One, paragraph 5 of this standard.
1. SCOPE.
1.1 Purpose.
Shock tests are performed to:
a. provide a degree of confidence that materiel can physically and functionally withstand the relatively
infrequent, non-repetitive shocks encountered in handling, transportation, and service environments.
This may include an assessment of the overall materiel system integrity for safety purposes in any one or
all of the handling, transportation, and service environments;
b. determine the materiel's fragility level, in order that packaging may be designed to protect the materiel's
physical and functional integrity; and
c. test the strength of devices that attach materiel to platforms that can crash.
1.2 Application.
Use this method to evaluate the physical and functional performance of materiel likely to be exposed to mechanically
induced shocks in its lifetime. Such mechanical shock environments are generally limited to a frequency range not to
exceed 10,000 Hz and a time duration of not more than 1.0 second. (In most cases of mechanical shock the
significant materiel response frequencies will not exceed 2,000 Hz and the duration of materiel response will not
exceed 0.1 second.) The materiel response to the mechanical shock environment will, in general, be highly
oscillatory, of short duration, and have a substantial initial rise time with large positive and negative peak amplitudes
of about the same order of magnitude.1 The peak responses of materiel to mechanical shock will, in general, be
enveloped by a decreasing form of exponential function in time. In general, mechanical shock applied to a complex
multi-modal materiel system will cause the materiel to respond to (1) forced frequencies imposed on the materiel
from the external excitation environment, and (2) the materiel's resonant natural frequencies either during or after
application of the excitation. Such response may cause:
a. materiel failure as a result of increased or decreased friction between parts, or general interference
between parts;
b. changes in materiel dielectric strength, loss of insulation resistance, variations in magnetic and
electrostatic field strength;
c. materiel electronic circuit card malfunction, electronic circuit card damage, and electronic connector
failure. (On occasion, circuit card contaminants having the potential to cause short circuit may be
dislodged under materiel response to shock.);
d. permanent mechanical deformation of the materiel as a result of overstress of materiel structural and non-
structural members;
e. collapse of mechanical elements of the materiel as a result of the ultimate strength of the component
being exceeded;
1
For high impact velocity shock, e.g., penetration shocks, there may be significantly less or no oscillatory behavior
with substantial area under the acceleration response curve.
f. accelerated fatiguing of materials (low cycle fatigue);
g. potential piezoelectric activity of materials, and
h. materiel failure as a result of cracks in fracturing crystals, ceramics, epoxies, or glass envelopes.

a) All sets of RAM come with stickers.
b) Overclocked RAM runs hot and the extra cooling would HELP keep the RAM stable.
Also ricer typically refers to people putting huge wings or ugly body kits that don't make the car faster. In most cases these huge wings might even make rearward visibility worst. I don't see how this is rice? So WTF? Where's the professionalism?

@heero884: Because it looks like this? Also, motorcycles only qualify as a "race" if you are a transformer or a go-bot. And you, sir, are no go-bot...
...a-are you?

Did the author not do his research? If you were to take a look at the high end DDR3 memory available on Newegg a lot of them include a fan.. and I believe a lot of us would rather take a bulkier heatsink than to add another fan to our computers.

@heero884: I found that picture by typing in "Rice Rocket" into google. So maybe WE were talking about bikes, but you weren't?
Also, THIS is a Rice Rocket-Bike with a ridiculous design that matches the RAM in the picture.

Second, your analogy is off because black people do not have nations that produces predominantly watermelons as its supporting agriculture and exporting product.
Honestly though, I think that the term "rice" has changed. "Rice" has become a verb that means to extremely modify a car for performance and looks. Black people do it, white people do it and asian people have a whole culture revolving around modifying cars away from the stock look. Therefore, the term "rice rockets" are not meant to be derogatory but just an adjective.

yep, it's vernacular, not hate speech. What about beanermobile? Sounds more racist, but follows the same formula: cultural food + word for conveyance = arguably racist slang term for a type of vehicle.
is a French car a cheese-wheel? Is a british car a banger-wagon? Is an Ethiopian ride an anjara-car?

If Mexico created their own brand of cars that were popular and imported the United States, beanermobile might not be derogatory and racist anymore. On the other hand, cheese-wheel and banger-wagon sound like pretty decent nicknames for Peugeot and Renault, or Aston Martin/Mini*kind of*/Jaguar. Kinda funny that British people actually call their sedans "4-bangers"

is it racist to point out that it's always affluent white people who always make a point of making anything with any reference to race 'racist'?

I've got a Core2Duo E6400, both cores are clocked at 2.13Ghz. So in fact, they already have.
08/04/09
The thing that gets tricky about this is that there are some single or dual cores clocked in the 3.5 - 4.0ghz range... but those aren't the highest end processors.

-Octopus Sex-
When octopuses reproduce, males use a specialized arm called a hectocotylus to insert spermatophores (packets of sperm) into the female's mantle cavity. The hectocotylus in benthic octopuses is usually the third right arm.
