BF4 and High Speed Ram

Tested at 1600mhz and 2000mhz. Even with a lower cpu speed. the game runs much better when the ram is maxed. In my rig memory, not cpu speed, is a bottleneck it seems.
 
i tried it with ddr 2400 ram and i didnt really notice a difference. switched back to crucial sport because the patriot runs at 1.65v i guess its bad for intel ram controllers at that voltage.

Nice! I'm awaiting and curious how other titles react. The adage that mem frequency doesn't matter with DDR3 seems invalid, eh?

Highly dependent on the title.

BF4 is an excellent example of a title that utilizes RAM bandwidth/latency efficiently.
 
I went from 16 GB of 8-8-8-24 1600MHz RAM to 32GB of 9-9-9-24 1600MHz and all I do is game. :( Oops.

I can run the 32GB at 10-10-10-27 1866MHz, but I'm not sure the gain is worth any potential instability.

32GB!!!

I'm running 16GB and in BF4 I never exceed ~3GB usage.

I could have kept 8GB and been just fine!

Yeah... memory prices were rising and it was only $78 bucks for a 16GB kit of 1.35V very low profile stuff so I just maxed it out. Apparently that was a bad decision!
 
So I don't have a baseline for using slower ram, but I usually get the little bird first with 2400mhz RAM.

I am first to load 100% of the time in BF4 which is pretty awesome as I always get the vehicle I want.

I'm sure it's mostly the SSD but the 2400 MHz RAM probably doesn't hurt.
 
My brother is putting together a budget build and I'm giving him my Corsair Vengeance LP 1600 (2x4GB) as part of his birthday present.

I need to replace my ram and since I mainly play BF4 I figured I would get some faster sticks this time. I have a massive heatsink so low profile is a must, and out of those available to me over here in Holland I have narrowed it down to these 2:

G.Skill Ripjaws X 2133 CAS9

or for 5 euros more

G.Skill Ripjaws Z 2400 CAS10.

Which of these two would you guys pick - faster speed but higher latency, or slightly slower speed and lower latency? Rest of my rig is in my sig.

Well for only $5 more of the same quantity the 2400 MHz is the obvious choice. The different in latency between CL 9/10 will be outweighed by the increased bandwidth 2400 MHz offers.

Latency in nanoseconds = CAS / (RAM SPEED / 1,000)

[Lower is better]

9 / (2133 / 1000) = 4.219ns
10 / (2400 / 1000) = 4.167ns

Sold! Thanks man, I'll order tomorrow.....
 
When I started playing BF4 I had 6GB with 333FSB. I moved to 8GB and 410FSB, which overclocked my CPU and RAM by 25%. My minimums in multiplayer increased by about 30%.

Can't wait to see how Mantle adds to the mix.
