Which DDR4 option would be the best?

lastchaosplay11 · Nov 16, 2017

Hey guys, so it's black friday in our country, and thought about upgrading my CPU/MOBO and ofc Rams. Well here are a few options but I can't decide how much Mhz I need, or if I need dual or single, I am really not aware of which one is better and worse.

It was easier to just take a picture:

800 LEI is around 200 USD.

My opinion is the 2x8gb 3000hz one

Do you have the website for those lei pricing?

Hi lastchaosplay11

Please list the MB and CPU you are using for better advice.

Hey there! Actually I do not have the new motherboard and cpu yet, but it would be a z270 and i7700k

On a website there's an i7 7700k for like 320$ (with AC Origins and Warhammer II too)

The i7-7700k officially supports DDR4-2133/2400MHz.

It is best to choose your RAM kit from the MB QVL for whatever z270 MB you choose. Wait till the MB is chosen as you are taking a risk re: Compatibility. Make sure you can return them if you can't get them to their rated speed.

Which CPU supports 3000?

Also what can happen if the ram is 3000 and cpu supports only 2400mhz?

MB: http://www.marketonline.ro/placi-de-baza/placa-de-baza-gigabyte-z370_hd3-socket-1151-pNSc0Nj0v-l/

Weird that a Coffee lake can do almost the same performance as a 7700K, but I guess because it's not overclocked.

Are you sure that an i5 would be a good choice if I want to buy the parts for the next 3-4 years at least?

Also I am really really thinking to buy this: https://www.pcgarage.ro/procesoare/intel/kaby-lake-core-i7-7700k-420ghz-box/ (selling the games from it, would be a 70$ cut)

vapour · Nov 16, 2017

7700k is done for Z270 MB, no upgrade path. Z370 is new and will support 1-2 more gens of Intel xx-lake CPUs. To me, it is no brainer to buy new.

vapour · Nov 16, 2017

Get 8600k if you can: https://www.youtube.com/watch?v=cz4wrJdk6LI
8600k can OC to 5.3 GHz with good cooler

8600k does not show up on that website yet

It depends on the strength of the chips IMC (Integrated Memory Controller) if OC RAM will work.
Unless you have considerable Bios experience in managing Primary Timings and Voltage, It's best to stick with a kit of RAM at the official frequency of your CPU and tested by the MB manufacturer.

3000MHz is considered as OC (Overclock). As this is not the JDEC standard, any XMP profile may not be recognized. They may or may not work and this is the risk you take. There is very little difference between 2400MHz and 3000MHz when gaming.
My advice is to select your RAM kit from the MB QVL that have been tested and known to work together.

Yea but why i5?

8700k is best if you can afford.

lastchaosplay11 · Nov 17, 2017

vapour :

I will just prolly wait until summer and buy something then. I really wanted this 7700k setup, so I remove this freakin bottleneck of my gtx 1080, but if u say that it's not really worth buying that, then okay.

This way 7700K would be like 250$, and 8700k is like 420$, so yea almost double cause u get no gift for that.

Also I really don't know how to OC processors.

lastchaosplay11 · Nov 17, 2017

vapour :

Btw I just checked and it says 8700K only supports DDR4 2666

vapour · Nov 17, 2017

Nope, http://www.tomshardware.com/news/gskill-coffee-lake-new-ddr4-specs,35616.html

MB will guarantee 2666 for ddr4, but can do 3000+ or even 4000+ if ram is compatible with MB. Check MB QVL list and buy tested ram models will guarantee 3000+ or 4000+.

Thank you very much for the advice!
