It's cheap but very good quality.
Yes. Heard these RAMs have Micron DRAM chips, which you normally find on premium RAMs such as Vengeance and Ripjaw etc!
It's kinda funny because used 4 gig 1066MHz sticks from unknown brands are going for 2.5k at Hafeez Center whereas I ordered this 1600MHz brand new stick for just 2.3k shipped!
P.S Can you tell me about your PC? I heard Kllisre RAMs don't like Ryzens in general and B450 chipsets in particular. Checked the comments section as well and almost all 1 star reviews are from people running Ryzen machines.
