1600/1866 MHz&CL9/CL10 for Gaming: Is there a performance difference?

cascoh · May 20, 2014

Hey guys, I am buying a new kit of RAM and not sure on which ones to get. Deciding on Corsair Vengeance or G. Skills. Is there a difference between 1600 and 1866? The price difference is nothing for me and I wont mind spending or saving the extra $5 haha. Also what is the difference between CL9 and 10?

The only difference is the MHZ.
With benchmarks the higher MHz will yield a better score.
In real world computing you will not see a difference.
Just get the model that is compatible with your system.
The CL9 will be a little bit faster. (In real world computing you will not see it)
The CL10 will be a bit slower.

Im not going to be going pass 1866, Ive read that the difference is little to nothing. So which kit should I buy then?

Nathan Willis · May 20, 2014

Get the one that is compatible with your MOB.
Read the manual and see. Not all RAM is compatible.

The 1866/9 is the faster of the two, and contrary to the above, it will also OC better, CL10 is a slower CL and tells you it's running on weaker chips, so NO, weaker chips will not OC better...In strictly gaming where DRAM is basically just a conduit for data, will see little to no difference, maybe a FPS or two faster with the 1866/9 sticks, and just additional info since they are both 1866 sticks there is no difference in the MHz

Nathan Willis · May 20, 2014

Agreed ^^^^

Tradesman1 · May 21, 2014

Being slower yes, but why go slow when fast is and can be perfectly stable, if you want slower can always drop to 1600, the idea of faster freq provides wider bandwidth, to allow more to be done at any given time, the reason they are CL10 is because the ICs (memory chips aren't strong enough to run at CL9, which is also why they are a much poorer pick to go with to try and OC....these days 1600/9 is entry level and 1866/10 is only a hair better

Ok, That is what I though. I guess the Moderator on here had no clue!

Not you, but another guy who gave me that info.

Tradesman1 · May 21, 2014

I've sort of specialized in DRAM for a number of years now, started helping out in the GSkill forums about 5+ years ago and became an Admin over there, there's not really a lot of folks that know DRAM or the capabilities, I've even talked with support folks at Corsair, Kingston, Mushkin and others and when you go beyond base timings and into secondary or tertiary, or capabilities of various CPUs, they are lost (not all of them, but most of their staffs)

Nathan Willis · May 21, 2014

That is why I always like to cross check the info I get. (In this case I just assumed I was wrong)

Tradesman1 :

Okay thanks for the info! So to clarify I want to buy this motherboard: http://www.canadacomputers.com/product_info.php?cPath=26_1207_1206_1201&item_id=061009 . So which one should I buy? Sorry for all the questions just trying to confirm so I can plan out the rest of my build

thanks!

It can handle all of those bus speeds. (MHz)

Just pick the RAM that fits your budget.

Tradesman1 · May 21, 2014

Of those the 1600/7 set would be the fastest performing, though at that pricepoint and if you are getting a K model CPU, for the same price might look at

Tradesman1 :

Im not overclocking the RAM, so would CL10 2400 be faster then the ones I provided in the links? Price for me within this range isnt a problem I just want the best RAM possible for gaming, not into much video editing. If anyone can help me narrow down this option thanks.

Tradesman1 · May 21, 2014

A 2400/10 set is made to run at 2400/10, what get's OCed is the MC (memory controller a bit and possibly the CPU to run at 2400... With a K model CPU it's perfectly safe...technically anything over 1600 on Haswell is OCing the MC as it's 'rated' for 1600, much as SB CPUs were rated to 1333, yet think I did over 80 SB builds and think I may have used, maybe 15 to 20 sets of 1600 sets, most of the builds were 1866-2133

Tradesman1 :

Okay sounds good, do you have an e-mail i am able to contact you at? I have some curious questions and I dont wanna ask everything on this thread haha.

Tradesman1 · May 21, 2014

Can drop me a PM through the site here

Well this still doesn't solve my question so I will ask you guys and maybe you can tell me..... I can get kingston 4 x8gb 1833 cl13 value ram the same price as i can kingston hyper fury 4 x 8gb 1600 cl 10. I dont game on pc much. I do run a fewf monitors at once and use my pc as my htpc on my sony kdl 55W900A with sometimes a lot of media running at once. I also store all my media in this pc. So for my 3 wifi tv's 2 of which have M8 quadcore Aandroid 4.4 xbmc streaming boxes connected to, this essentially is my storage for all the media running to them as well as my xbmc htpc, surf the net, and 4-8 monitors running with just text on each. I guess my question is what should my focus be on? The Video Cards more then anything else? Should I Be trying to upgrade my 2 6870's over getting the 16gb of extra ram or worrying about 1600 cl10 over 1833 cl13?I do have more pc's that I can use for whatever reason I need them for in this set up I am aiming for. So for example I could use an older pc as a nas? From there what would exactly that do for me and should I have my media on another pc?

Tradesman1 · Jul 27, 2014

Across multiple monitors (mentioned 4-8), multiple windows, streaming, muti-tasking, etc - yes you would see a difference, and going lite on the amount of DRAM is going to result in the data thrashing back and forth to the page file on the harddrive
