16gb kit or 8gb
Written by: Sc0tty - 23:41 Jun-02-2015

So I have came to a dilemma, as of late. I've kept it in the back of my mind for the longest time to get a full set of 16gb ram.

And before you ask, but you only need 8gb ram for gaming!
I want to concur that with, times are changing my friends. Games are getting more and more demanding, I'm starting to do so much more with my computer. Rendering, multitasking, video games. You name it.

But I now come to you with a question. Being a fairly tech savy guy myself, I know the dangers of mixing ram and that it's JUST better to buy them in a full set. Ha like batteries :D
But anyone who knows me knows that, heh we all have other bills to pay.

So the question is, do I add another 2 sticks of 4gb into my system, or just suck it up and buy a full damn set of 16gb. Ontop of that, does anyone have any horror stories contradicting to mixing ram?

The ram I have in my system is from my build in 2013, so it's roughly 2+ years old now.

[g.skill Sniper Series 8gb](http://www.newegg.com/Product/Product.aspx?Item=N82E16820231519) is that kit I currently have. Thanks guys.

Get a 16gb kit or get a 8gb kit?

Personally, I'm gonna say get the two sticks of four/one stick of eight.
And well, I've never had any issue mixing ram.
Above all, simply make sure the frequencies are the same, alongside the cas latency.
Hope this helps!

requirements that...you guessed it, will go even higher than that. But by all means, if you don't care about max settings, 8GB will be ok. But 8GB is just starting to not be 'of the times' anymore. Not everyone NEEDS to get exactly 16GB, get 10-14GB if that suits your fancy. Get more ram the slower the frequency too.

(1/2) As far as mixing kits, don't do it. You will hear many people say "I've mixed kits for years and I'm still running fine". Well that's well and good but unless you want instability, crashes, freezes, lockups, etc. stick to the same kit. I also think 16GB is what everyone should have now. Games have 8GB (1/2)

If money wouldn't be an issue I'd go for 16GB with a 32-bit OS ;P

Haha, I like your smart answer! Could definitely be a way out in that 32-bit situation :P I recently read about it! Not something for me (yet), but have you tried and tested it?

ofc I tested it, even made tutorial video hundred years ago xD
haven't tried on 32bit OS though - yet I heard it's possible to put pagefile on RAMdisk and so you can actually have much more than about 3.5GB ram on 32bit OS

Sure, why not? You can set up multiple page files :D


I saw your vid and read the comments! It could be interesting to reserve 100 - 200MB, for especially temp files. I recently tested my system without having Superfetch enabled (disk activity vs. in-memory load), but its algorithm works better than I thought. I have it enabled again, but saw some disk activity I prefer not to have (don't bother with SSDs guys ;) It's minor, but RAMdisk could reduce strain here...
I just never tried it because of my 3GBs :P

I've used different size sticks before and they're completely fine. I can guarantee you won't notice the difference because, as with everything to do with memory, you are mainly limited by your storage speed. Nothing but a good SSD RAID 0 system can come close to RAM's speed to begin with (also one of the reasons why USB 3 is also technically an overkill and yet we will have an even faster one).
Just add another two sticks, possibly 2x8GB even.
I have 24GB here - 8+8+4+4 :)

May I first ask you this question: if you start your PC, what's your RAM usage in an idle CPU state? (Doesn't necessary have to be technically 100% idle, but you get the point)


Your CPU has 2 memory channels and your motherboard supports Dual channel, so I'd always go for 2 x ...GB in that case to enjoy that extra bit of dual channel boost. I also recommend to install RAM sticks from the same brand to avoid possible incompatibility...could be the case with Flex Mode (term I know): e.g. in my situation and my 3GB RAM, I've got 2 x Dane-Elec RAM, one's 1GB, the other 2GB: I enjoy dual channel, but only for 2/3GB because size matters here: best is to go with 2 x 2 or 2 x 4 for example.


Also: do you really have DDR3 2133(MT/s) RAM? I read that speed is supported by your mobo, but CPU @ 1600MT/s...


PS Get a 8GB Kit, advised 1600MT/s then.
PPS Would be nice if you could share a pic from your system under stress > Resource Monitor > Memory (tab) > Ram 'in use' + 'modified' :) I'm interested and curious!

1600MTs/800MHz is official limit, but these CPUs easilly take 2400MTs/1200MHz atleast

Always had my question MARKs at some of Intel's specs and values ;)
If the reported maximum memory bandwidth would be 25.6GB/s, not taking a dual or triple channel setup into account, 25600/8 = a 3200MT/s data rate = DDR3 3200 should be supported in my opinion....but there you have your mobo limit @ 2400MT/s in this case ;)

Just want to emphasize the importance of getting the same kit of ram for all sticks that Mark noted in his comment. Incompatibility is the main issue here.

erm, I don't clearly see why not get 2x8GB kit so you can try to run 24GB ram in total? :D

I'd go for 4x8GB = 32GB quad channel :D
8gb modules used are getting cheaper...you can just sell the ones you currently have.
RAM is always useful, you can run multiple VMs, make huge ramdisks, etc.


In my case I need at least 16GB for work.

1150 mobos don't support "quad channel", you can put 2 sticks in one channel and 2 into other channel :D

My only issue with RAM is making sure I get the right kind. My Inspiron 15 took 8 chip sticks, while my Alienware takes 4 chip sticks.

since youre starting to do more demanding tasks ('Rendering, multitasking, video games. You name it.'), I would upgrade to 16 gigs. If you want to spend the money, you could just buy a new 2x8gb kit, but personally i would just add another 2x4gb kit

I agree... If you have two free slots already... Just get 2 4 GB ones...

Just buy another kit of the G.Skill's you already have, you can't really have too much ram.
In general, if two different kit's of ram have the same ranks (Eg. Single or Double sided), timings,
voltage & frequency they should work just fine together.

Agreed, I think that's the route I'm going to take. It just makes more sense really, I might run a memtest on this ram just to assure that there's no faulty sticks.
Everything runs great. But it'd completely make sense to rule out faulty sticks with a whole new kit.

I probably have the one weirdest Ram setups in my rig and don't have a single problem with it(z87/97 is much more stable with mixed up ram then the old s775 motherboard for example)


If you just want 16GB i would reccomend a 2x4 as close as possible to your currrent one(voltage, frequency, timing).


The only real reason to take 2x8GB in your situation is if you want to get even more ram in the future(like 24-32gb).

Eaxctly, I plan to buy the EXACT same kit as I have now. I love it and it runs at a decent speed... The cas could be better but at 2133 you can't expect much!

you could also sell the ram you have and put it towards credit for the 16gb kit

All my friends are deals savs, they'd be like. Cheaaaa right. I'll give you 20$ max for your 2 year old ram haha. I do have 4gb of tactical tracers from crucial lying around. I used to put them in my system, they have purdy lights.
But they downclock my ram to 1600mhz. In which is absolutely fine. But being the arse I am the higher the speeds, the cooler I feel. Y'know. Lol

erm... I am not sure how to answer the poll xD. the questions is 8 16 GB and the answers are yes or no :P. But anyway when I bought this rig 2 years ago it had 8GB of RAM on it. A couple of months ago I added a third 4GB stick. So now I have a total of 12GB of ram. All is fine. No problems or anything. All 3 sticks are Kingston 4GB DDR3 1600mhz but the third one isnt the exact same as the others. Or at least it looks different. So I say just get another 8GB. or 4 like me :P.

if you consider upgrading to Zen and/or Skylake get the 8gb kit, save your money and buy ddr4 RAM, otherwise go for the 16GB kit 8GB is good for gaming, but this is not a console, you should expect to have a lot of background apps running at the same time, plus if you render it RAM helps much more than a strong CPU.

I don't plan on going Zen or skylake, I just came from the FX line. The 4790k is top notch for gaming right now. If skylake has some megalodon suprior rendering CPU thats = to or better in gaming around 350$ usd. Then I'd be like, hey maybe its time to upgrade. But haha I don't see it happening.

Then go for the 16GB
And Skylake will be 2-8% better(4-5% average) than haswell from some leaked benchmarks, I expected it to be at least 20% better per clock/ 20% higher IPC, still it's not official. Zen will be at least on the same level as Sandy-Bridge -10% lower IPC than than Haswell if what AMD says is true.
Both Skylake and Zen will have 512 bit AVX 3.0, which will most likely be useless for 99% of the people and give no benefits outside synthetic benchmarks, even AVX 256 bit just starting to get adopted and is quite useless as well.


So yeah, the bottom like is get the 16GB Kit.
