Samsung Ceases B-Die

https://wccftech.com/samsung-b-die-memory-production-ceased-replaced-by-samsung-a-die/

Samsung stopped B-Die production, replacing with A-Die. I don't know anything about A-Die or how good it will be. But I'm thinking I might buy some B-Die ram while stock still exists.

I know for example GSkill makes AMD optimized TridentZ 3600 and nearly guaranteed to be B-Die.
- I've seen plenty that claim this ram can run at 3866 @ CL16, for those on Ryzen.

I currently use Corsair w/ junky Hynix 3200 @ CL 14 15 15 17 28. So just a heads up if you wanted B-Die ram.

 

Seriously get your B-Die while you still can. B-Die runs at 3600 CL14 w/ wicked tight timings on Zen+

I expect to be running 4200 CL19 with Zen2.

 

what if the new a-die is better than b-die in every possible way

 

Possibly. But that's not the reason Samsung killed off B-Die. A-Die will be denser, need less of it, it's a cost thing.

I think Samsung is trying to release 16GB/32GB stick ram at a reasonable cost with A-Die. And considering for the average user like me, there is no difference in performance between 16 and 32, both on W10 and Ubuntu.

Hynix has been making A-Die for a while now and it's not impressive.

But you may be right, but also wrong. Just saying, for those who have been eyeing the B-Die and putting it off until their next upgrade, buy it now while stock is still available. I already see prices creeping up.

Also I know ram speed above 3200 seems to make no difference. I'm just hoping with Zen2 it might.

 

I think, but I do not recall that my hyperx impact dies are B-die, or some variant of it called K4A8G085WB-BCPB. Any info on that? As for next upgrade, I would just wait till DDR5.

 

Still hard to find, here's some info on A die memory, but it's likely not ready for prime time performance yet with such bad timings - at least in this one example:

First Samsung A-Die Memory Sighting Points to Low-Priced DDR4

"Samsung B-die memory chips are pretty much considered the holy grail for hardware enthusiasts and overclockers. You can imagine the hardware community's disappointment when word got out that Samsung was retiring its B-die offerings in favor of the company's more recent A-die memory chips.

Samsung used to produce the famed B-die memory chips on the 20nm manufacturing process. With A-die, the memory manufacturer is moving to a more recent 10nm node. Sadly, memory products with A-die are still pretty scarce at the moment. There isn't sufficient data to see whether A-die is better or worse than its predecessor.

The Samsung A-die DDR4 module, which was spotted by a Hardwareluxxx reader, is identified by the M378A4G43AB2-CVF part number. It's a dual-rank stick with a capacity of 32GB.

If you recall, one of A-die's promises is to offer higher density per module. The Samsung module is rated to run at 2,933 MHz with CL21-21-21 timings and a 1.2V operating voltage. The memory speed is pretty decent, but the timings certainly leave a lot to be desired. However, keep in mind that the A-die is still wet behind the ears; the timings will most likely improve in time.

MemoryCow, a United Kingdom memory and storage retailer, has listed the Samsung M378A4G43AB2-CVF module for £128.33, excluding VAT (Value Added Tax). So, we can expect to see the module costing around $157.77, which would be the cheapest DDR4-2933 32GB module on the market. The only other stick that has identical specifications comes from Crucial, and it commands a $171.99 price tag."

It is out of stock right now...
