Pros: I achieved better timings @ 3600 than similar 3600 specced memory, at a similar price and using less voltage. Looks great, and I really only care about performance

Cons: None yet, only ran a few benchmarks to test stability, but so far so good. After installing Asus Armour Crate only one of the sticks lit up. Not the fault of the memory but the board/software. Removed the armour crate software (actually reinstalled windows) and never reinstalled it. lloks nice to me and I have now desire to play with lighting effects, this is a work machine.

Overall Review: I bought this knowing that it was unlikely I would be able to run 128gb @ 4000 on my asus dark hero motherboard with Ryzen 5900x. However for the extra $20 over the 3600 16-22-22-42 @1.45V equivalent neo I thought it would be a better option to try and change settings to 3600. With just a little experimenting I settled on 3600 at 16-19-19-38 (settings of the 64gb 3600 kit) @ 1.42V, which I am very happy with. Reducing timings further even with a slight increase in voltage failed to post, but I am more than satisfied with this to try more lengthy experimentation
