Need an advice

[elhayekmichel]

Hey,
i have 1 stick 16 GB hyperx fury 2400mhz.
should i get another 16 GB stick or should i get a 3000mhz 2x8 GB ?
im confused between the predator RGB 2933mhz and the tridentz rgb 3000mhz
i need some help please
i have a 8700k, 1080ti asus and i just use my pc for gaming and sometimes video editing

mixing different speed ram for new gen platform is not recommended, it may work but has complications. I would suggest find a retailer with good return policy and try the same fury stick first. Otherwise, just sell fury on ebay and buy 2x16 gb kit.

i dont have any problem with it, i just want to get 2 sticks to run it in dual channel thats it.
and im not mixing different speed of ram, i have 3 choices:
- get another one like the one i have right now
- sell mine and get 2x8 gskill tridentz rgb 3000mhz
- sell mine and get 2x8 hyperx predator rgb 2933mhz

What FPS are you getting? Is it under par? If not, you don't have to change.

soemtimes i get some fps drop for a long period of time , but no my fps is good

I assume you have an SSD? How does the video editing go?

 

[photonboy]

1) 2x2400MHz (CL?) in most situations should not cause a CPU bottleneck but I can find some that will (mostly CPU-intensive applications not games)

2) what can you SELL it for?

3) will you ever use more than 16GB?


If not, probably best to go with 2x8GB 3200MHz DDR4 CL15 (or close) to maximize your bandwidth if you're going to the effort of changing.

Then run MEMTEST86 for a full pass www.memtest86.com

yea i got an ssd 850 evo and M.2 ssd 960 evo
its great, i was just wondering if ill get a better performance if i get a +3000mhz ram

i have 1 stick 16 GB hyperx fury 2400mhz CL15
i was thinking about the predator rgb 2933mhz,
i dont think ill use more than 16gb, and if i will ill add not a big problem.

I won't bother if I were you. Yes, there will be improvements but may not be much.

First off, for the sake of simplicity we will say the following: 1x2400 = 2x1200

So I'll just look at some worst-cases but unfortunately the used DDR4 bandwidth for the above testing only goes down to 2x2133 (essentially 1x4266) so your results would be lower.

In areas where it shows MINIMAL BOTTLENECK at 2x2133 there may or may not be a bottleneck at 1x2400. I have no way to tell unless I can find a better article.

*anyway, I'll go back to Hitman at 1280x720 which I realize is not practical (you'd game at higher resolution but even at 1920x1080 there are still drops) but it's still indicative of some other scenarios as you can see with WINRAR, more CPU-intensive games etc.

So... 78%
In Hitman the FPS drops to 78% at 2x2133 of what it could be with no DDR4 bottleneck. Thus YOU would get lower in the same setup with 1x2400 instead.

If I extrapolate the data into an algorithm of bandwidth vs performance I get an answer that suggests you'll drop to roughly 60% of max performance in some situations (which could include higher 0.1 and 1% lows average in demanding games thus having more stutter in demanding situations despite the average FPS appearing higher).

To be fair, you may see minimal benefit to upgrading to say 2x3200 CL16 memory depending on the applications and games you play. But... as per the data that's not necessarily guaranteed.

so the minimum in that test is 4266 and mine is only 2400.
i guess my only choice is to have 2 sticks of ram right ?
plus i play at 2560x1440
