Samsung Starts Offering First A-Die Based RAM
Samsung's B die has been widely known as a good, high performance variant of DRAM memory, loved by overclockers because of its ability to get to a high frequency with relatively low timings. However, B die has been discontinued and now Samsung started offering its replacement in form of the newly developed A die manufactured in 1z nm (1z class) lithography process. Despite the lack of technical details surrounding the new die type, Hardwareluxx has received a tip from its reader about new RAM offering that incorporates A die memory.
The M378A4G43AB2-CVF, as it is called in the listing, is a 32 GB, single dimm DDR4 RAM with operating speed of 2933 MHz and CL21-21-21 timings. This particular offer isn't something to be excited about as the frequency is good, but the timings are quite high for that speed. Given that we don't know where the A die is targeted at, we can speculate that its current aim is at mid-tier systems, where the mediocre performance is okay and the system isn't suffering (performance wise) because of it. Nonetheless this find is quite interesting as it gives first hints at what can we expect in therms of future A die DRAM offerings. Remember, it took some time for B die as well to get to the level of performance we have today, so it is entirely possible that A die will improve and try to aim for greater performance level than it currently has.

Glad so far i have ordere Memory with Samsung B-die for my up comming Ryzen 3000 build rated for 3600 MHz CL 14-15-15-35 at 1.4 volts. hoping with a bit more voltage i can cram timmings down to CL14-14-14-32.
Sure A-die is in its infancy, but i will not wait a year or longer for A-die to get better. B-die for life and now.
JEDEC spec ram are there to just work on just about every platform without any setting required.
There is no real way to determine how well a new type of IC overclocks except to get some and try.
The JEDEC specs of B-die is "laughably slow" as well.

Not to even mention you're comparing overclocked DDR3 to stock JDEC ddr4 at 32gb per dimm, which is currently clocking poorly as it's still rather new.
and considering my ddr3 kit was literally the lowest ripjaws x bin id say its doing pretty good
unrelated but its a different idea, would SODIMMS clock higher as the pcb is smaller and hence the data has less difference to travel or would it introduce crosstalk due to being more dense
How the same chips perform with 1.35V is still an open question.
Basically, Samsung made a proper RAM for normal people - not to attract overclockers and such. This should keep the price down. Good stuff.
