In computing, DDR4 SDRAM, an abbreviation for double data rate fourth generation synchronous dynamic random-access memory, is a type of synchronous dynamic random-access memory (SDRAM) with a high bandwidth ("double data rate") interface. Released to the market in 2014, it is one of the latest variants of dynamic random-access memory (DRAM), some of which have been in use since the early 1970s, and a higher-speed successor to the DDR2 and DDR3 technologies. It is not compatible with any earlier type of random access memory (RAM) due to different signaling voltages, physical interface and other factors.
DDR4 SDRAM was released to the public market in Q2 2014, focusing on ECC memory, while the non-ECC DDR4 modules became available in Q3 2014, accompanying the launch of Haswell-E processors that require DDR4 memory.
The primary advantages of DDR4 over its predecessor, DDR3, include higher module density and lower voltage requirements, coupled with higher data rate transfer speeds. The DDR4 standard theoretically allows for DIMMs of up to 512 GiB in capacity, compared to the DDR3's theoretical maximum of 128 GiB per DIMM.
Don't quit your day job
Corporate-crybaby
A bit wiser and a whole lot older, feelin' bolder
Suckin' up to the last stockholder with a
Golden parachute slung over your shoulder
Jacked-up-B-boy
Another fool got stuck in the whirlpool
Lookin' for a fast break, not enough cake to go 'round
Another brother goes down, and he's out of the gene pool
Media-pimp
Day after day, night after night if the money is right
The campaign goes on to make right seem wrong
With computer animation and a hip-hop song
Land of opportunity, this is the
Stop
Don't quit your day job
Cowboy-politician
Suckin' up to the aristocracy
Not even sure if you like democracy
Tryin' to establish an american royalty, a personal dynasty
Priests-of-the-airwaves
Let the buyer beware, it's a jungle out there
So buy my advice and don't think twice
Then me and your money will go someplace sunny
Celebrity-stud-monkey
Kiss and tell, got a book to sell
'Cause you don't excel or do anything well
Since you slipped past thirty, better keep the sex dirty
Mo' money, mo' money, mo' money
