Can i use 2133mhz with 8700K or should i buy 2666mhz?

Hi. My rams:

https://www.kingston.com/datasheets/HX421C14FB2K2_16.pdf

Currently are on Asus Z170-P motherb and 6700K. I am buying 8700K and Asus Tuf Z370 Pro Gaming.

https://www.morele.net/plyta-glowna-asus-tuf-z370-pro-gaming-1612190/

I must buy faster new ram and sold actually or not necessary ? I dont have much money and i must safe cash for gpu.


So this mean i will be have bootleneck? So right now me having lower MHz ram than Intel actually recommends slows down the CPU or not really?



They said:

"The minimum memory frequency we would recommend for a high-end Coffee Lake system is 2666 MHz. Everything below that seems to have relatively large performance effects."

In Witcher 3 20 fps difference between 2133mhz and 2666mhz.



I am using 1080p monitor 144hz, GFX Gtx 1080 ti


And why on intel specification is 2666mhz memory,look:

I don't see that massive differences here. If you're short on cash ram is the last thing you should care about.

You do realize in that benchmark that there are different CPUs right?

 

I have very small acount of cash. I must have money to buy 1080 ti aorus. Somebody said that 2133mhz will block 8700k performance is this true?

Of course i can sell my actuall ram and buy 2666mhz but is this worth? But like i said i must get cash for 1080 ti ,and actuall i have small account of cash.

 

You won't experience any noticable bottleneck at all.

 

So i can stay at this time with 8700K and 2133mhz and buy 1080 ti aorus. And after month i will buy faster ram. Is this good choise at this moment?

 

Depends, if you have meh cooling i'd rather save up for proper watercooling or big air cooling like the noctua, ram is one of the last things you should care about. Unless you run very specific programs that need ram, which I'm pretty sure you don't.

 

So 2133mhz using only for 1 month with 8700k and 1080 ti will not bottleneck my cpu to very low performance?


Nah my cpu fan will be Cryorig I9. I must safe cash for 1080 ti : )

Cryorig M9I Intel (CR-M9I)

8700K will not OC. It will be enough?

 

No it won't. You can have 4ghz ram and you won't notice a difference unless you start MSI afterburner and look at the FPS and notice like 2-4FPS less than u had previously.

 

I bought Cryorig M9I Intel (CR-M9I) cpu fan cooler.
It will be enough for 8700k without oc?

 

nah man anything in that pricerange is meh.

Noctua NH-D15 is the best air cooler you can get.
Dark Rock Pro 3 is also good.

Best price per performance would be something like Scythe FUMA

If you like Cryorig you can try and get a Cryorig R1

You should always overclock a 8700K. If you don't want to overclock then go for non K versions. 8700K without overclock is a waste. In 1080p CPU is still somewhat important especially when you run a 1080TI, you will gain a LOT of performance when overclocking the CPU, compared to buying new ram.

You have a 144hz monitor 1080p, which overclocking CPU is almost mandetory.

 

Ok but i must save cash for gpu. So i choose Cryorig M9I Intel (CR-M9I). So my question is. Cpu will be have good temps on load without oc ?

 

Probably. I don't know exacly since I don't really check up on low end CPU cooler.

 

So choosing my rams 2133mhz 2x8GB ( actually ) , and buying this cpu cooler Cryorig M9I Intel (CR-M9I) cooling to safe cash for 1080 ti will be not bad ?

 

nah it's bad. The proper thing you should do is buy 8700K, good cooling, overclock and get a GTX 1070. The 1080ti will be bottlenecked all the time by your CPU because of your 1080p monitor. If you had a 4K monitor the story would be very different, in your case overclocking the CPU as good as u can and getting a 1070 will give you much better frames than stock 8700K and 1080TI.

 

SO there will be not problems to fit Cryorig M9I Intel (CR-M9I) cooling on this fractal design 5?

Dimension L92 mm x W92 mm x H25.4 mm ---> they said 25.4mm in height

http://www.cryorig.com/m9.php

The Define R5 supports:

CPU coolers up to 180mm in height

can you check please ?

 

Why here are so many difference?

Test is on the same 8700K . But different ram speed.

 

I think you rather should get advices from @D2 Ultima who know more abou this topic.

 

Wait what? What's the question? About RAM speed?

 

Read it one more time

 

There's posts by someone I don't feel like scrolling through, but sure.

 

Hi.

I would not bother with that motherboard. Get ASUS Prime Z370-A or ASRock Z370 Extreme4. You rarely need anything more, and you don't want anything less.

You want 3000MHz minimum for intel chips in a high end gaming rig.

You may not "bottleneck", it depends. You WILL however, 100% guaranteed, not utilize your CPU to the maximum potential.

1080Ti is a good pair for that if you want to play with maximum details all the time, for sure.

That's a crappy 1080Ti, I don't know why you'd waste your money on that. EVGA SC Black or SC2 is better, and ASUS Strix is also better. And I think usually cost less too.

Yes, it will hinder the performance of your 8700K. Enough so that an overclock is less effective than buying faster RAM.

You are going to need to plan out your building. I would even say, that directly for the purpose of gaming and nothing else, I'd axe the 8700K and get the 8600K and top notch RAM and a good cooler with the savings, and just overclock it to somewhere around 5GHz give or take.

 

Buy a single stick with 2133MHz ram now and fill in the second later is a terrible bad idea. Even with 6700K.

 

If it's only a month, unless you are getting a great deal on other components, why not just wait the month? No point in buying RAM for a month then buying new RAM.

 

its more then likely so he can get the system up and running, from the benchmkarks I have seen there isn't really any benefit from 2133 to 2666 why don't you do youeself a favor and hit the sweetspot in the middle at 2400 for now, that seems to be the cheapest option atm that's what I use and it shouldn't have any sort of noticeable difference between 2133 or 2666 I have a i5-6600k the one in my sig, I have a 1080ti arous the refrence card style I had in this rig before I took it out for another build and it didn't bottleneck at all, neither does the asus 1080 turbo I have on this rig currently this pic is at stock clock on the 1080 and rarely does any of my cpus go over 65-70% with my oc (+285 cpu +575 mem) so a 8700k even with a very mild OC should be fine and I am able to push this rig far look at the cpuz scores and the heaven scores the heaven score is with my oc on it just fyi

 

There will be *some* bottlenecks, but it would be so negligible to human senses to catch it, although if your ram are OCable, you can overclock them if you mobo bios supports it!

 

Are you serious?? Aorus is the best brand for any gpu, best cooling then evga!
In past i had a 1070 aorus and i compared it to rog strix 1070, msi aero 1070, evga sc 1070 in a local exhibition of pcs, guess what aorus ran cooler then any 1070 and with 1fps more then its second tier rog strix1070!!

 

Every single Aorus 1080Ti I've seen reviewed has sat in the 90c range with low boost clocks. What your 1070 did is irrelevant to a 1080Ti.
