In my quest to find the best DDR4 JEDEC 3200 SODIMMs for laptops and mini PCs I found this strange memory stick and it seems way too good to be true. According the specs I can find it looks to be perfect, so I am pretty skeptical. The specs are:

JEDEC
DDR4 3200
CL 15
dual rank
X8 chips

Prior to this the best I have ever found were HX432S20IB/16 and HX432S20IBK2/64 which have the same specs with only the CL being different, CL20. CL20 to CL15 seems like way too big a gap to be real. Does anyone have any actual verified info on these?

Curiosity got the best of me, I ordered 2 sticks. They arrive tomorrow unfortunately I am out of the country until the 13th, I will see what we have then.

That is literally the best laptop ram I have ever seen, so it is really hard to believe it is legit. Not only is it the lowest CAS latency (by far) I have ever seen for SO-DIMM DDR4 3200, but it's also doing it at 1.2v on a JEDEC profile.

At this moment the best JEDEC SODIMM I have ever personally verified is DDR4 3200 CL20:

HX432S20IB_16.ai (kingston.com)

HX432S20IBK2_64.ai (kingston.com)

To the best of my knowledge this is as good as it gets. We will know soon, I will absolutely post screenshots of everything including memory benchmarks before and after. These will be going up against the good memory I listed above.

Yep, its fake. I'll get pics in a little bit but CL is not 15 at 3200, its not even 20 (like the best Kingston kits). Its pretty ordinary CL22 DDR4 3200 and there is no XMP so the CL15 is entirely fiction.

Turns out that even CL15 at 2400 is not that great because the Kingston kits listed above do CL15 at 2666 and CL14 at 2400.

These are better than average sticks being marketed as impossibly top tier.
