Should i buy this or corsair vengeance pro rgb bus 3200? this ram is currently cheaper in my country but i never use thermaltake ram before. I plan to upgrade my rig to R5 3600 and B450 mainboard, thanks!

You want the best RAM die for your RAM sticks. So, GSkill has in some Samsung B-Die, Crucial has Micron E-die and Kingston has Hynix and for some Samsung's and Micron's. It is interesting to learn what Thermaltake has chosen to use for those sticks. For that MSRP price, I guess Micron's E-die at best, Hynix at worst.

So i just checked this one, it has Hynix C-die.
