Is All DDR4 SDRAM?

[CmdrJeffSinclair]

Hi,

All I see on Newegg is RAM that s SDRAM. I don't want that. Where the heck is plain old

G.Skill/Kingston/Corsair DDR4 3000MHz that is not labeled as SDRAM? Newegg's all have the SDRAM label on them

All ram is classified as SD ram be it DDR3 or DDR4. http://whatis.techtarget.com/definition/SDRAM-synchronous-DRAM

This is not true.

SDRAM stands for Synchronous Dynamic Random Access Memory and refers to a particular family of DRAM designs established by JEDEC in the early 1990s. Furthermore, DRAM refers to a particular type of RAM.

Not all SDRAM is DDR4 SDRAM, not all DRAM is SDRAM, and not all RAM is DRAM.

DDR4 SDRAM is the 4th generation of JEDEC DDR SDRAM and the 5th generation of SDRAM which includes the original 3.3 volt SDRAM (now commonly referred to SDR SDRAM).

There is also DDR SSRAM and QDR SSRAM, which are themselves variants of SRAM and not DRAM. Ergo, although DDR is often used to refer to JEDEC DDR SDRAM, it can also refer to several other designs.

Ah, so should I avoid SDRAM? It was my understanding that for common users and gamers SDRAM wasn't better, but that DDR was the best. From what I read at least for the DDR3 generations of RAM, SDRAM clocks were timed to the CPU which was better for things like servers but not as good for common computers and usually had a focus on ECC memory, which is not the case for the modules I look at. I always buy non-ECC Unbuffered RAM, and SDRAM usually is ECC.

Everything DDR4 on Newegg says DDR4 SDRAM. I don't want it if it is not as good as regular DRAM. I do understand a lot but there is surprisingly little information on DDR4 at the moment.

DDR SDRAM is a variation of SDRAM, as is DDR2 SDRAM, DDR3 SDRAM, and DDR4 SDRAM. They're all evolutions of the basic SDRAM design which was introduced in the early 1990s. Even their graphical variants (GDDR SGRAM) trace their lineage back to the original SDRAM.

DIMMs that feature ECC simply have an addition SDRAM chip which extends the data bus to either 40 bits (32 bits of data + 8 bits of ECC) or 72 bits (64 bits of data + 8 bits of ECC).

SDRAM (and its descendants) are the dominant form of DRAM, but there are others available on the market for use in special applications.

Asynchronous DRAM (DRAM that does not rely on an externally driven clock signal) fell out of use in the early 1990s.

thank you!

But still the ram modules we use in consumer platforms is SDram since it is synchronized with the clock speed of the CPU's that we use in our common computers.
