No, this model isn't commonly found as a B-Die.
Hello, I purchased a RAM module that needed to be returned because of a malfunction. The store provided a replacement, but it contained different chips—specifically, a Samsung B-die instead of the E-die found in the original unit. The model I’m referring to is the G.Skill Trident Z 16GB Kit DDR4 3200MHz (CL16-18-18-38) F4-3200C16D-16GTZB. I’ve learned that B-die modules are favored for stability and over-clocking, though some sources indicate only very tightly timed kits use B-die, like the CL14 series. Others mention that F4-3200C16D-16GTZB doesn’t have a B-die. I checked an online B-die finder tool and confirmed it didn’t list this particular kit. There’s also a discussion thread about Samsung B-die confusion, which doesn’t mention this model either. I wasn’t complaining, just curious if this specific kit typically includes a B-die. Since it’s a fairly affordable option, I was thinking about the higher-end models such as CL15 or CL14, which do guarantee B-die. I’ve attached a photo from a shop called Thaiphoon Burner with the details. Thanks for your attention!
Someone misread the specs, possibly confusing Hynix CJR with Samsung B-die or Hynix AFR with Samsung D-die. You need to remove the heatsink for accuracy. It’s accurate that Samsung B-die isn’t in certain memory ranges, especially those with strong performance claims. There are subpar B-die options that act like decent Hynix AFR, but they often can’t reach high frequencies like 3333MHz with tight timings. Finding quality B-die from cheaper, well-known brands is even harder than from smaller ones like Team Group or Patriot, since those have more resources to produce better binned dies. For instance, many claim 3600MHz is ideal for Zen 2 CPUs, prompting Corsair to create a new 3600MHz range to attract more buyers from the 3200MHz area. Previously, their weakest bins were 18-22-22-42, while the new ones sit at 20-23-23-43—still not great. In the past, these dies might have ended up in 3000MHz 16-18-18-38 kits, alongside those that simply can’t go higher. So they’d push the limits just to make more money.
The builds I'm testing are using B-Die configurations. (G.SKILL Flare X Series 16GB, 2 x 8GB, 288-Pin DDR4 SDRAM, DDR4 3200, PC4 25600) AMD X370 / B350 Memory (Desktop Memory), Model F4-3200C14D-16GFX - available at Newegg.com) These models feature tighter clock speeds but haven't shown strong performance gains. The other kits I own that deliver higher speeds are the G.SKILL TridentZ Series 16GB, 2 x 8GB, 288-Pin DDR4 SDRAM, DDR4 3600 (PC4 28800), Intel Z170 / Z270 / Z370 / X299 Desktop Memory, Model F4-3600C16D-16GTZSW - also from Newegg.com) These are clearly the top B-Die options. The other components I have (G.SKILL Trident Z Royal Series 16GB, 2 x 8GB, 288-Pin RGB DDR4 SDRAM, DDR4 3600, PC4 28800) are also B-Die. Some of the other sticks (G.SKILL Trident Z Royal Series 16GB) are B-Die as well... It seems the better performance came from Trident Z models, while the Royals are a solid alternative if you can't find them elsewhere. The Flares are decent, but expect limited gains beyond what's already stocked.
In the best possible situation, Thaiphoon might have misread something or the hardware was of poor quality. I didn’t adjust settings, but they function properly at the standard speed (2133Mhz) and reach the advertised rate with XMP enabled (3200Mhz). Both tests using memtest86 showed no issues. The product comes with a lifetime warranty, so if problems arise—possibly from defective chips—they’ll be replaced. The link you shared is Beerzerker’s, which is almost identical to the one I’m sending back, but the 3200Mhz model. I built my system over Christmas and noticed this kit was available for a low price—about £70 (GBP) at https://www.ebuyer.com/772381-g-skill-tr...16d-16gtzb. I verified the MSI Tomahawk Max QVL, but the F4-3200C16D model wasn’t listed. I bought the CL14 version (F4-3200C14D-16GTZKW) since it was available on the QVL. It arrived without problems, passed repeated tests, and I sent it back after a BSOD in January. Since it wasn’t officially supported, I ran it through Memtest86 three times—each time errors appeared after about three hours. I repeated the test several times and consistently found faults, leading me to believe the instability was linked to compatibility issues. Eventually, I received a replacement kit, but it was the same model as before. While waiting, I checked MSI’s QVL and found the closest official listing, which matched the CL14 kit you linked. The 3200Mhz version was available on Amazon, but it had the same issues. I’m now considering returning the CL14 kit because it was cheaper, yet still had B-die chips. The price gap is huge—almost £100 more for the CL16. Is there any advantage to using the CL14? I’ve heard Ryzen 2600X benefits from B-die and faster components, but this budget model is still quite fast.
