dasa 20 Posted October 8, 2013 (edited) The performance gains are much bigger than i expected but i triple checked the results and there is well under 1fps difference between most runs at the same settings so if somebody else would like to give this a go to confirm or disprove my results it would be interesting Arma 3 stratis 1600-2133 15.369 % increase Arma 3 altis 1600-2133 11.477 % increase Test System 2600k ASUS Z77 MAXIMUS V GENE 2X4G SAMSUNG 2133 (10-10-10-24-1T used for all tests) Two 7970@1050\5600MHz crossfire is enabled not that it makes any difference at 1080p 2TB 7200RPM with OCZ Synapse 128G Cache Seasonic 1000W Platinum win7 64 cat 13.10 beta2 Tests were run at high detail 1920x1080 unlike last time on the alpha http://forums.bistudio.com/showthread.php?153524-CPU-VS-RAM-Performance-amp-CPU-Threading-Benchmarked with 16g 2400 c10 ram being within $20-50 of 1600 c10 ram i think this is useful information for those considering replacing there pc and goes against the results of other ram performance tests in games due to most other games being gpu bottlnecked --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Late edit with some new tests i have run some new tests on ram timings but there is obviously some inconsistency with the tests since i only bothered to run them all once with 1600 8-8-8 performing the same as 9-9-9 in one test and 9-9-9 performing the same as 10-10-10 in another this is just a hickup one 7970 is now dead so im back to a single gpu for these tests minimum fps in altis was to inconsistent to bother including current ram prices in au 2x4g 1333 9-9-9 $93 1600 11-11-11 $89 1600 9-9-9 $103 1600 8-8-8 $109 1866 9-10-9 $105 2133 11-11-11 $102 2133 9-11-10 $115 2400 10-12-12 $125 2x8g 1333 9-9-9 $152 1600 11-11-11 $175 1600 9-9-9 $203 1866 10-11-10 $199 1866 9-10-9 $205 2133 11-11-11 $205 2133 9-11-11 $225 2400 10-12-12 $229 Edited March 11, 2014 by dasa Share this post Link to post Share on other sites
tremanarch 6 Posted October 8, 2013 thats interesting - time to overclock the ram ^^ Share this post Link to post Share on other sites
MavericK96 0 Posted October 8, 2013 Likely due to the massive amount of I/O streaming textures and whatnot the game does. Share this post Link to post Share on other sites
verstand3n 13 Posted October 9, 2013 yes interesting! thank you! 2400Mhz Cl10 is not that more expensive either... Share this post Link to post Share on other sites

fabio_chavez 103 Posted October 10, 2013 there was another benchmark with that result some month ago, thank you for confirming this! very intressting. (remind me to get rid of my 1066mhz ddr2 :/) Share this post Link to post Share on other sites
St. Jimmy 272 Posted October 24, 2013 I got G.Skill RipjawsX DDR3-1600 DIMM CL9. Is there a chance to go for 2133 or should I give up before even trying? Share this post Link to post Share on other sites
roni 11 Posted October 24, 2013 This show how arma is very different from most other games, where ram frequency almost doesn't matter. Also would be nice to see differences with for example 9CL and 11CL rams. Share this post Link to post Share on other sites
Fushko 59 Posted October 24, 2013 That's quite a big FPS boost. See ya, gonna destroy my RAM trying to overclock it. Share this post Link to post Share on other sites

big_t 1 Posted October 25, 2013 Interesting test, thanks for the discovery. I'm also wondering about cas latency, I'm thinking it might effect fps as well as it is related to overall ram speed in a way. Share this post Link to post Share on other sites
jumpinghubert 49 Posted October 25, 2013 Altis-Bench old ram: 2000mhz (11.11.11.30.1T): 47fps new: 2666mhz (11.14.13.36.1T): 49fps not so much I hoped. system in signature. Share this post Link to post Share on other sites
roni 11 Posted October 27, 2013 What if my MB supports 1600mhz ram max, and I use faster? And if I buy 1600mhz rams, can I overclock it more than 1600mhz with this MB ? Share this post Link to post Share on other sites

roni 11 Posted October 27, 2013 H87 performance aka fatal1ty, and would like to overclock rams more than 1600mhz, because as we can see it help give nice fps boost. Share this post Link to post Share on other sites
dasa 20 Posted November 12, 2013 (edited) here is some tests on haswell that show the importance of getting a balance with timings\frequency http://www.anandtech.com/show/7364/memory-scaling-on-haswell/10 its just console ports unfortunately but still useful and here is something else to look out for with newer high performance ram that can make higher speed sticks slower http://hwbot.org/newsflash/2125_the_truth_about_hynix_mfr_based_memory_kits___overclockers.coms_g.skill_tridentx_8gb_ddr3_2933_memory_kit_review Roni does your mb have settings in the bios for taking the ram higher than 1600mhz? JumpingHubert it might be worth overclocking the ram try leaving at 2666 but tightening timings to 10-12-12 or as low as you can get and do you have any pics of your rig? i used a toyota camry heatercore in my rig several years ago :) the old heatercore before upgrading to the thermochil 4x120 rad Edited November 12, 2013 by dasa Share this post Link to post Share on other sites
mordeaniischaos 3 Posted November 14, 2013 Altis-Benchold ram: 2000mhz (11.11.11.30.1T): 47fps new: 2666mhz (11.14.13.36.1T): 49fps not so much I hoped. system in signature. This sort of thing would certainly have diminishing effects at higher clocks. If you were starting a 1600 and moved up to 2666 you'd find a bigger boost than say 2666 to 3600, most likely. Eventually the game overcomes the bottleneck and it doesn't matter nearly as much any more. Share this post Link to post Share on other sites
grillob3 11 Posted November 24, 2013 Arma 2/3 is a cpu/ram overclock whore game! GPU oc does not effect that much. Share this post Link to post Share on other sites
galzohar 31 Posted November 26, 2013 GPU is the main factor in which graphic settings you can run smoothly (all else put aside, aka mission that doesn't bring your game to a crawl due to heavy CPU load, and "heavy" doesn't mean 100%, just that the FPS drops due to CPU-based operations). CPU is the main factor in running non-graphical-related things like having a lot of units/AI active on the mission. Both are important, and which one should be more important to you depends on which one is your weak link (bottleneck). Share this post Link to post Share on other sites

izaiak 1 Posted February 6, 2014 Does switching from 8 GB PC 16000 CAS 7 to 16 GB PC 16000 will also increase performance ? Because i read on Arma 3 feedbacktracker, arma can go over 3,4, or 5 GB of RAM due to some tweak already into the game. I'm not a master of that so i can't explain how it works. But i never see anything testing the game with 8 GB or 16 GB of RAM. thank you. Share this post Link to post Share on other sites

I had 8 gig of RAM 1600 and I went for 32 gig 1600 (for After Effect, not Arma) and I saw no differenceI guess performance gains are more about the 1600mhz => 2333 mhz Share this post Link to post Share on other sites
