Have a 5900x and a Dark Hero on the way and am looking for the best RAM that isn't super crazy priced. It also would Ideally fit under a NHD14. Currently looking at 2 sets of this CORSAIR Vengeance LPX. Is there something else that's better that I should be looking at?

Anything higher than 3600 MHz might not work and if does work wont be a whole ton faster
Anything slower than 3600 MHz and you start to lose performance and it does not matter a whole ton what CAS you get 3600 MHz in so CL16 is fine

And last buy a kit with four in it dont buy two kits with two they might now work together so you are better off with either a bigger kit of two or a kit of four

This isn't true. As long as you get exactly the same model two kits of two sticks is just as likely to work as one kit of four sticks. There isn't anything that makes the four sticks work better together. At the same timings there is no difference between 2x dual kits and 1x quad kits.

The one exception to this is that they usually don't make four sticks with timings quite as low, so those timings are more likely to work than the two stick kits with the lowest timings. If you are not pushing the timings for what the memory controller can run two sticks per channel at, there is no difference between dual and quad kits at all. The manufactures don't test for matching DIMMs or bin sticks for two DIMMs per channel or anything like that.

Those are great in my experience. I can run these timings on either of the two kits I have:
2514471


VDIMM is at 1.40V

True, that is basically what the settings above are too. My timings are slightly better then this motherboard's B-die @3600-1.45V preset, but that difference makes almost no improvement in performance.

14-14-14-30 is enough better than the 16-16-16-36 DOCP/XMP settings that it is worth setting something faster than DOCP. That memory is almost guaranteed to do 14-14-14-30 at 1.45V. :)

You should invest in a 3600mhz CL14 RAM. G.skill tridentZ neo has one, you can find them on amazon or newegg.

Reason for that it because 59xx performs way better with lower CAS(CL) and 3600 is the bare minimum you need for 59xx anything lower than 3600 you are just wasting your money on the cpu.


Dont get CL16-18 RAMS no matter how high the clock speed u are loosing out 20-30% extra performance (about 30-40 fps in game)

Simply enable XMP profile and you are good to go.

If you have extra time, you can also manually tweak your RAM timing to get significantly better performance (free performance)


It may sound and look confusing but actually it is very easy.

U can check out this tutorial

While I agree that some good 3600-14-14-14-34 memory is highly recommended, and those G.Skill Trident Z Neos are great, 20-30% is an outlier. The difference is not very close to 20% compared to 3600-16-16-16-36 DOCP v.s. 3600-14-14-14-34 DOCP.

You are presenting Shadow of the Tomb Raider as expected results when in reality it is unusually memory sensitive and we still only get 20-30% change comparing 3600-16-19-19-37 XMP to 3600-14-14-14-30 manually tuned. A huge amount of the performance comes from the manual tuning as well.

On Intel, so not directly comparable. Any one have a better dataset? :oops:

Greetings, I made the purchase of these RAMS apparently because they are compatible with my BOARD which is an ASUS DARK HERO and I use RYZEN 9 5900x, I have had problems with the HyperX Predator ‎"HX436C18PB3/32" RAMs, especially when I increase the MHZ of 2400 to 3600 MHZ, my question is if I will not have future problems with this RAM since on the DARK HERO official site page they recommend x4 G.Skill of C18 like the ones I just bought.
