Just poking my head in to simplify the whole "Which kit has what ICs"...
That old program
Thaiphoon Burner is still around and kicking, which received a couple updates in 2017, latest being a couple days ago. I already knew (well... highly suspected) my TridentZ 3200 15-15-15-35 kit had Sammy B-dies, but this actually confirmed it for me. The program is free for this sort of usage, it's the SPD Programming that are locked out by the license fee.
Here's what my TridentZ's output:
EDIT: Despite what the shot shows of 15-15-15-36, my box and DIMM sticker say -35
EDIT2: Ignore that, it shows the correct timing in the XMP profile at the bottom. I'm just blind.
Oh also worth mentioning I suppose... MSI X370 Titanium with a 1700X (China) and shipping BIOS v1.10 (E7A31AMS.110) runs them at 3200 no problem. Only quirk is it seems to favor JEDEC#7 instead of XMP, even with the A-XMP enabled. Which results in my timings being 16-15-15-35. Further curious is that even when I manually SET tCL to 15 it is 16. And when I set it to 14, it is... 14. *shrug*(
