Hi all. I'm thinking of upgrading my RAM from 16GB to 32GB, but in the process I would also like to gain some additional speed if that is possible ? Currently I'm using 4x4GB G.Skill Ares 1866MHz CL9-10-9-28 2N 1.5v kit. I have been looking at this memory kit since it's one of the cheapest with these specs I can find: G.Skill Ares 4x8GB 2400MHz CL11-13-13-31 2N 1.65v. The system is a MSI X79A-GD45 Plus with Intel Core i7 4930K@4GHz. Will there be any gain going from 1866Mhz to 2400MHz ? I have scrolled through tons of reivews but I haven't gotten a real answer as if it's noticable within daily work ?. I see differences in synthetic benchmarks. Also with gaming I have seen in some youtube video's from Digital Foundry that more MHz ram speed does increase FPS ? I've also seen Linus' old video, where it's shown 1866mhz cl9 actually edging out 2400mzh cl11 ? It's really confusing ?. Maybe i should jeg get another 2x kits of 2x4gb 1866mhz ?
To be honest man, i upgraded not long ago from 1600mhz cl8 to 2133mhz cl10. There is no game i noticed any performance difference besides some synthetic benchmarks like Aida64 memory bandwidth test (24mb's vs 33mb's). It would probably help in some insane cpu bottlenecking situations where higher memory bandwidth can help.
Thanks for the answers Well it is probably also just the "upgrade itch" itching to try something else, but then again if it's just a waste, then I could probably find better use of the money other where in the pc.
You have a Z68 based board and no doubt a Sandy Bridge CPU? The Z77 + Ivy platform has some improvements (not sure whether it is chipset related or memory controller related) that meant you got a much better peformance difference between 1600 and faster, such as 2133, than on a Sandy CPU and Z68 chipset. It's why many of the RAM speed comparisons are inaccurate, because they were done at the time with Sandy and not Ivy. Anyways, it all depends on whether the X79 platform and that CPU got the improvements with the change or whether they skipped this and applied it to Haswell-E. In either case, if the cost is much the same or only slightly more, makes more sense going 2133 regardless. At least you will be able to sell it easier later!
YA no diff really, real world, maybe gain some in min. FPS that's about it, and that's only 1-3 fps maybe if lucky.
If you play Fallout 4, then it will be worth it. Look up some benchmarks on what RAM speed can do to that game. I went from low 40's average FPS with 1600MHz to mid 50's average FPS with my current RAM. This was back when I had an R9 290 OC'd to 290X speeds and the game was on a mix of High/Ultra settings @ 1080p.
Well I got a kit of 4x 8GB EVGA SuperSC 2400MHz DDR3 CL11 memory and a kit of 4x 8GB G.Skill Ares 2400MHz DDR3 CL11memory incoming, so I'll try out which one works better.
faster ram only helps cpu performance in software that needs data that hasnt been preloaded to the cpu cache in anticipation of its use by the time the cpu needs it you already have heaps of bandwidth with quad channel ram so extra probably wont make much difference you may see some gains in cpu efficiency if you can get a lower latency but nothing noticeable on its own 1866c9 to 2133c9 or 2400c10 would be a small to moderate step 1866c9 to 2400c11 is a tiny step barely measurable i have put together a collection of tests here a few posts down http://forums.anandtech.com/showthread.php?t=2474056 best way to find out if higher speeds will have a impact on your software is to lower your ram to a slower speed and see if it has an effect
the upgrade will be worth it if you plan on keeping open a lot of programs. you can also turn some of the ram into storage memory for a specific game your trying to get max bench for then bench it vs your ssd. also you can try more aggressive timings.
While not an entirely accurate performance metric, you can calculate a comparison number by dividing the frequency by the latency. Obviously higher number is better when comparing modules with different speed and latency. 1866 / 9 = 207.33 2400 / 11 = 218.18 Gives you an idea but like said doesn't account for everything. Faster memory has always more bandwidth than slower memory.
Since the OP was talking about upgrading to 32 GB and replacing their existing modules in the process, it makes sense to go 2400.
Been wondering about this very thing myself, for the last few months ive been running 4x4gig of Corsair vengeance pro 1866(silver) but wanted to colour match my ram to my system and i noticed a popular choice of the i7 4790k owners is 2400mhz ddr3, the 4790k according to intel uses dual channel 1333/1600, now if there is suggestion that faster ram has little effect on gaming why do companies try to push for faster ram, do the newer breed of cpu beyond z97 chipset benefit or is it the same for the likes of the 5820k and the 6700k. I have opted for 2x8 Corsair vengeance pro 2400 in red.
Well, ive got my new 2400 Corsair ram in and although there is no change in fps as far as gaming goes..... my system does appear to operate a bit snappier
