Hi all

I will be upgrading my system soon as my CPU which is currently i5 3570k is bottlenecking my new GPU, and to boot, I have a really slow DDR3 ram.

I will be going with an intel i5 6600k and DDR4, though I havent completely settled on which mobo just yet. I seriously like Gigabyte boards for the dual bios and ruggedness such as https://www.amazon.com/Gigabyte-LGA1151-Intel-Motherboards-GA-Z170X-GAMING/dp/B017KE82IU/ref=sr_1_12?s=pc&ie=UTF8&qid=1472809336&sr=1-12&refinements=p_n_feature_seven_browse-bin%3A10656895011%2Cp_89%3AGigabyte%2Cp_n_condition-type%3A2224371011 , but I am also open to other boards at this time. Haven't decided yet if I would be better off going with 2x 16 or 4x 8 GB sticks.

So I have some questions about DDR4 RAM, specifically, I have some concerns after I have done some research and read reviews etc. and would like to hear some of your guys feedback, experiences and pointers.

I would like to go with the 2666,2800 or 3000 MHz RAM, I understand that I will have to use XMP profile in order to utilize that. But I also have read a lot of comments under reviews, where people had really bad experiences. Most often was that the RAM would not go above the 2400 MHz or even 2133 MHz regardless of XMP. Has this happened to anyone ? If so, which RAM was it ?

Is there any particular high MHz (2666+) RAM that simply works straight out of the box without having to resort to XMP, or just simply has no issues whatsoever doing so ? Not causing any system instabilities etc. ?

I am also looking for "low profile" at the same time because its very difficult to fit too large RAM sticks with my CPU cooler. So far, unfortunately the sticks that fit the other criteria (being high speed) are Corsair, and these are the ones that have the most issues clocking over 2133 MHz even when advertised as 2400 or 2666. My current DDR3 is also in the same boat. Using XMP it either doesn't want to go up or causes system instability. So I would like to avoid the Corsair low profile.

So looking for recommendations for RAM, DDR4 2666, 2800 or 3000 MHz as follows:

Works out of the box at the advertised high speeds without too much hussle with XMP crap or causing system instability.

Low profile preferred, or at least reasonable height, not like those huge, gigantic G Skill ripjaws that I can't fit into my system.

I'm also open to suggestions for better mobo then the one I picked, must be same or lower price range, must have dual bios or some sort of bios safety backup thingy I can easily use for those times when I screw up while updating it. And of course have native support for i5 6600k and DDR4 high speed RAM.

Thanks


 
The Asus Z170 AR has a feature called EZ XMP so all you have to do is switch on EZ XMP on the motherboard, it also has a thing called MemOK! Which I believe test the ram to make sure it will run with the system. Also make sure your ram is compatible with your motherboard, I just learned today that my Crucial Ballistix sport 16G kit isn't compatible with a Asus Z170 AR mobo so make sure you don't just grab any old ram thinking it's just fine. Also you'll be fine with two 8G sticks.
 
I can tell you, I'm using a 210€ board with 16GB DDR4-3000
I was to lazy to really get into things, but if I use auto settings on XMP I get a random blue screen 7/10 times my computer is running
but from what I've heard so far, if you manually set it up using try&error you will get it running at almost any speed you desire

from what I understand it's less about the RAM as about the combination RAM/board (as long as your RAM is listed as compatible)
the least issues I've seen with Corsair Vengeance so far (but they also come with worse timings than Kingston/GSkill. not that 1ms more or less would make any significant difference) and GEiL Evo potenza (but again it's not as popular as the other RAMs so there will naturally be less reports)
also it's a bit of luck if your chipset/board likes the RAM or doesn't it seems....
 
I ended up going with Asus Maximus VIII Ranger, and 32 gigs of Patriot Viper, 3200 MHz in 2 pairs (4x 8GB). Enabled XMP and the auto tweaks, works freagin awesome. I tweaked my case fans to get a bit more cooling on the RAM.

Also should mentioned, Asus released brand spanking new BIOS and Drivers for these boards just a couple days before I bought my stuff. I ended up runnign my CPU at 4.6 GHz (thats using auto tune) and Ram at max, decided to tone it down to around a modest 4.1 GHz and let it place the RAM wherever it wants.

Now there is one slight thingy that irks me a bit. My RAM is 3200 MHz, board supports up to 3400 or 3666 (I forgot which, but I gave it some head room). And everything works great, even under real heavy load in mass PVP MMOs with 100-300 player battles.

I'm getting some great results from HWMonitor as far as temps and voltages go, however, the one thing that bugs me a bit, is that my CPU-Z reports my RAM at 4000 MHz + ..... How and why ? Neither the board nor my RAM itself is capable of 4000 MHz, so this has to be a bug ? Or is it ? If its not a bug then that might not be so good, because I don't want my RAM dying on me prematurely and possibly taking something with it.

I should add that the RAM speed is reported correctly in the BIOS, but not Windows.
 
I'm also leaning towards the BIOS, but since I initially noticed this, I have also tried it out with RAMExpert, Intel XTU, and Memory Viewer, all with pretty much same results, only minor differences. So its whole Windows that sees it like that.

To boot I also spend last 2 hours or so on google searching, but the closest I got is that some of the initial release 170Z chipset boards (rev 1.0) had bad bios and some bad interaction between bios + windows, and I had to dig for that through product reviews on Amazon and Newegg and there are no solutions posted. I have brand new bios, flashed from defaults via USB and my board is also already revised, not an original model. I made sure of it.

I added and repositioned my case fans, so my RAM maxes out at 52 deg C under heavy continuous load, CPU maxes at 62 deg C and GPU at 74. Rig is a little bit louder for having 4 case fans 2 of which running at high speeds, but I figured better safe then sorry.

We'll see how it goes.
