Possible bottleneck?

[KarathKasun]

2133mhz memory is not ideal for a gaming build focused on minimum FPS.  I would say that 2933 would be the minimum.

 

There is a good chance that you can overclock your memory to ~2933.  Bump memory voltage to 1.35v, increase timing values by ~20% (or leave them on auto, some boards will automatically calculate optimal timings based on the stock speed/timings), and set the memory speed to 2400.  if that works, try the next fastest memory speed.  Rinse and repeat until the machine refuses to boot or things start crashing, then take it one step back.

Should i buy two of this? G.SKill Trident Z RGB DDR4 RAM 8 GB, 

• 2x 8 GB DIMM, 3866 MHz
• Do they fit my motherboard? z270x ultra gaming couldent find it on the list but its pretty new so the maybe didnt upgrade list.
• Should i buy 4 times 4 gb or is it as good buying two with 8gb?

Will i get a better fps just if i buy 2*3600ghz ram sticks 8 gb, or should i overclock my cpu and then get the fps or will i even get a higher fps just from buying new memory with higher frequency? Right now i have 2100 ghz.

This will very from game to game, but you may certainly see performance increasing by getting faster ram. I've included a video below featuring some benchmarks from certain games. Not mentioned in this video is Watch Dogs 2. This game significantly improved by increasing the ram speed in my own previous system. I had gone from DDR3 1600Mhz ram to DDR3 2400Mhz and got a 15-20fps increase in that game. In LTT's video about the difference in ram, 2133MHz vs 3600MHz mean the difference in 22FPS in Rise of the Tomb Raider. But they're the same speed in games like Deus Ex: Mankind Divided. 

 

At this moment I would be more worried about RAM compatibly. It's important that we find the source of your stuttering. Ram not made to work with a certain mobo mean your system either not booting at all to desktop, or poor/inconsistent performance. Ram is pretty expensive right now, so I don't want to necessarily personally recommend to go out and buy the fastest ram available. But yes, you may certainly see the difference.

Your mobo has support for DDR4 3866(O.C.) / 3800(O.C.) / 3733(O.C.) / 3666(O.C.) / 3600(O.C.) / 3466(O.C.) / 3400(O.C.) / 3333(O.C.) / 3300(O.C.) / 3200(O.C.) / 3000(O.C.) / 2800(O.C.) / 2666(O.C.) / 2400 / 2133 MHz memory modules. BUT that doesn't mean that every ram stick will be compatible with your board, even if it does fit snuggly inside. 

As I mentioned before you'll want to refer to this document to see if ram you have or want to purchase is compatible with your board: http://download.gigabyte.us/FileList/Memory/mb_memory_ga-z270x-ultra-gaming.pdf

 

Unfortunately the 8GB's of G.SKill Trident Z DDR4 RAM 8 (F4-3200C16D-16GTZR) you mention is not listed on the document of supported RAM for your motherboard, so it difficult for me to recommend. It simply could be newer ram and they might not of tested it yet and updated the list. Just be aware of the return policy if you happen to pull the trigger and buy it.

Buying 2 sticks of ram is usually always best, as you'll have the ability to easy add another stick of 8GB ram later on if you ever wanted a total of 24GB's or 32GB's of ram. Right now you need 32GB's of ram to play Star Citizen 3.0 if you hope to get over 30FPS.  Yeah, that game is really poorly optimized right now. But for 99% of other games 16GB is more then fine. Performance wise in gaming the difference between 1x16, 2x8, or 4x4 is negligible.

I know some might be critical of telling people not to buy ram that isn't found on a compatibility list, but I've been in that situation before. Late last year I purchased 8GB's of ram DDR3 ram from Best Buy, who I should mention does not accept opened ram for returns, and the RAM did not work in a PC I was building for my wife. Low and behold it wasn't listed as compatible for my mobo. I ended up selling to a friend whose computer was listed as compatible and they are still using it to today.

 

I'm aware this rarely happens and that with DDR4 is this still less likely happen, but it's still worth checking and consulting before making any final decisions. At the very least be aware of the return policy of the place your buying from before taking risks.

Please check out my journey which was quite similar to yours, here:

 

 

Hope it helps.

 

Also for best low latency, good frame rate and no tear effect, please see https://www.blurbusters.com/

They have a super comprehensive guide on this topic.

 

This also helped me:

 

In my case since i have a gsync 100MHz monitor, i now use RIVA tuner to cap the framerate 3 fps below monitor refresh so 97; gsync on; vsync on in nvidia settings; vsync off in games; and run timeresolution to drop dpc latency to 0.5, mouse pulling at 1000. But the smooth as butter experience, no tearing nor any microshutter really take gaming to a whole new level. Thr limits required for gsync and reduced temperatures, by a significant margin.
