Salyginis sitas Crucial'as .. ankstesnis man labiau patiko (daznai ji ir kisdavau):

The timings between the two are also slightly different as the tRAS and several advanced timings are shown as being different. This is the first DDR4 memory kit that doesn’t have 2133MHz speeds for the base JEDEC profile, so it looks like Crucial is confident that no board on the market will have issues posting at 2400MHz. Crucial didn’t program an XMP #2 profile on this memory kit, so those values are blank.

Gaunasi, kad automatiskai jis nepagaus 2133MHz ir geresniu nei CL16 timings'u.
Tuo tarpu Kingston'as turi apsirases mazesnius timings'us prie 2133MHz.

Jei ieskosi kazkokio - bandyk rasti CPU-Z printscreen'u:

2133MHz atitiks 1066MHz ... pagal JEDEC #7 rodo CL 15-15-15

Bent jau kolkas http://www.skytech.lt/search.php?keywords=HX426C15
DDR4-2133 CL12-14-14 @1.2V --- DDR4-2666 CL15-17-17 @1.2V
Sakyciau gan teisingas, taciau kaina palankesne imant 4*8GB 
(jei 32GB per daug, tarsi su kazkuo per puse pasiimti draugiskai 266.69/2=133.35 Eur)
