16 gb ram usage on sonar x1 64 bit

Ditch the Soundblaster and get a proper audio interface, designed specifically for DAW use

First culprit I'd look at is your soundblaster, they are not really made for music production so you won't get low latency and no pops and cracks, they don't have good optimized ASIO drivers (If at all) and are made to play games and simple audio.

Second is your system is a gaming machine, they come with beefed up gfx cards  that are not always good to have in a DAW build.

Check if you have any problems using this:

Large sample libraries like Omnisphere or Kontakt, orchestral libraries with many articulations etc.. are the plugs that will benefit from lots of ram, soft synths will use CPU and hardly any ram.

That system should not have any trouble playing back lots of soft synths and a ton of audio tracks, somethings wrong somewhere, I have a good hunch like Jonesey mentioned that it's the soundblaster card.

you are also running sonar 64 and not 32 bit version ;-)

omg u guys are so awesome - so i set it up to notify me when i got a response and since i got no notify i assumed noone liked me lol ok so maybe it's me being a noob... like i said i know systems and i know mine is bad ass although not in a gamer sense cause graphics arent important in my studio except for the ability to run 3 to 4 monitors in which case i had to ditch my long loved nvidia for ati cause the least expensive nvidia i could find that supported more than 2 monitors was around 400 bux and the ati 5750 was like 130ish i think... anywho. random tangent of nerd brain... sorry that happens sometimes. so like i started, maybe im being a noob cause in my projects i have like 8 to 10 synths with huge libraries and all running live at the same time with very rare dropouts. the latency setting is set for 2 buffers at 10 ms i think and i record 64 bit at 96000khz broadcast waves when i export. but playback is usually fine, i do have the occasional dropout like i just did which reminded me to check this lol and really my problem is i forget to save and forget to set autosave... im doing that now. but i just had read somewhere awhile back there was a largeaddressaware command or code or hack or something to tell ur computer that this particular program get a devoted x amount of ram. with 16 gigs i can spare alot it rarely goes about 5 unless im dloading alot, i just thought there was a mod, that would rule. i would like to get an m box or that cakewalk box i saw a while back, that would rule too, just havent had the cash to upgrade yet. and though i rarely have problems, i thought id check. i also run the mic from the booth in through an maudio firewire solo preamp, but i use the soundblaster elite for everything else. u guys some cool responses. so i tried the latency thing and it just went on for like half hour but never got abover the 500 mark although it said it was testing to 1000. yet, i have no idea how to read that thing. it said the machine should be able to stream audio and video with no problems if thats what we're looking for there. I also dont use the ASIO on my soundcard, i use WDDM i believe its called? I sometimes have crashes when i delete a synth or effect thats not being used like guitar rig 4 or battery, and sometimes the sound just stops and i have to reopen sonar and it works again. I've been trying to pinpoint the source of these annoyances but other than a querky guitar rig and battery im lost... i typically use 2 or 3 kontakt synths for differnt banks i have and then a string or garritan orchestra, and most my projects have zeta and dimension as well, then i used various different piano synths depending on the song. so it's like hip hoppish orchestra with technoish synths mixed in... usually. so... theres no mod? like i was thinking in the settings part where it says u can edit the sonar config file maybe it could be done there... i want it to have like the full potential of my system when it's running and theres so much extra ram with 16 gigs... im repeating myself... thank you for all your help so far by the way u guys are awesome. i love sonar. i even have it tattooed on my arm lol
