The first is an OEM bulk version of Provantage, priced at $179; then ShopBLT, also in bulk, priced at $189.88. At the same time, they also confirmed the product number: FD4100WMW4KGU.
ShopBLT has also received FX-8000/6000 series bookings before, the price is only 10-15 US dollars higher than the official price, according to which the final price of FX-4100 should be calculated in the 175 US dollars up and down.
So why are the four-core FX-4100 and the six-core FX-6100 almost the same in price? In combination, we only saw the bulk version of the FX-4100 without a boxed version. It can be speculated that this quad core should be mainly supplied to OEM PC manufacturers pre-installed on the brand machine, and the six core and eight core are to attract retail consumers. The main force.
In fact, there are already many OEM desktop brand machines that are ready to load the FX-4100, such as the Acer M3450 (product number PT. SHDP2.001), such as Fujitsu's ESPRIMO P705 E85 +, which also optional Socket AM3 interface Phenom II X4 960T/X2 560, Athlon II X2 265/220.
A siren is a loud noise-making device. Civil defense sirens are mounted in fixed locations and used to warn of natural disasters or attacks. Sirens are used on emergency service vehicles such as ambulances, police cars, and fire trucks. There are two general types: pneumatic and electronic.
Many fire sirens (used for calling the volunteer fire fighters) serve double duty as tornado or civil defense sirens, alerting an entire community of impending danger. Most fire
sirens are either mounted on the roof of a fire station or on a pole
next to the fire station. Fire sirens can also be mounted on or near
government buildings, on tall structures such as water towers,
as well as in systems where several sirens are distributed around a
town for better sound coverage. Most fire sirens are single tone and
mechanically driven by electric motors with a rotor attached to the
shaft. Some newer sirens are electronically driven speakers.
Fire sirens are often called "fire whistles", "fire alarms", or
"fire horns". Although there is no standard signaling of fire sirens,
some utilize codes to inform firefighters of the location of the fire.
Civil defense sirens also used as fire sirens often can produce an
alternating "hi-lo" signal (similar to emergency vehicles in many
European countries) as the fire signal, or a slow wail (typically 3x) as
to not confuse the public with the standard civil defense signals of
alert (steady tone) and attack (fast wavering tone). Fire sirens are
often tested once a day at noon and are also called "noon sirens" or
"noon whistles".
The first emergency vehicles relied on a bell. Then in the 70s,
they switched to a duotone airhorn. Then in the 80s, that was overtaken
by an electronic wail.
