i was just wondering why you need so much
ram in a studio computer?
i upgraded from 500 mega too 1 giga ram
and when i look how much im using its only about +-350 or something in a track with around 35 audio tracks.
so why do you need so much? |

vsts use ram too. not as much as a huge 32 bits audiofile, but surely they'll use ram too..
vsts and other applications have to be in system ram to be executed
to make the reading of audio files faster, parts of them are store in ram to make the sequencer more usable...
usually algorithms are used to optimize the cpu/ram load roll a joint or STFU :) |

I have 1GB 400DDR, since it's dual then it's 2GB and i use only 0.9GB at the end of my work in Cubase. I guess RAM speed/CPU speed/MOBO much more inportant here than additional memory, 1GB should be enough for any kind of job.

so how much audio tracks and vst's do you use for 0.9 gb of ram?
and is their a way to waist less cpu and fill more ram?
because my cpu is loaded but not my ram.

I use 30audio 15vsti and effects on most of them.
You can't! RAM and CPU are different things but Cubase shows their combination so you can't know what RAM or CPU loaded or not.

Hi Tuk 
Powercore or UAD1 card can solve CPU problems since u can use them for reverbs, compression and some effects. That or mixing down to audio and closing some vsti's; every computer has its own limit of how many channels and vst's and plugins, its not just a number since it also depends on which vsti's and plugins you are using.
Also if have processor with hyperthreading, then go into the bios and turn it OFF. This made cubase run much more stable for me, performace meter is not jittering so much... and some friends have same experience.... its because cubase and vsti's etc are not programmed to support hyperthreading.... or so i am told...

Just to mention, UAD1 costs way to much, i would try to use offline effects and bounce to audio all non constant VTSi signals. It can drasticaly reduce CPU overload of anykind.
*non constant i mean signal which modulates or have another wanted internal effect which applies each time in different form.

or instead of using many inserts, made group channels with the plugins you use the most, then send the midi and audio channels to the group channels so you dont need to open new instance of same plugin for each channel.

Well it can work with delays(flange,reverb..) only. I think offline processing is much more efficient in that case.

First thing to be sure of it , is the Frequency of the Ram, and wish type it is , there 3 kind the SDRAM,DDRAM, and RBusRam!
I don't recommand you to use SDRAM as they reach just 133 mhz it their clock speed, go for DDR for up to 800Mhz, and perfectly the RBus are the best but expensive !
Try to adjust them in your Bios of the motherboard, but read carefully its manual, to change it's speed after looking if they are on maximum or not!
Vstis use Memory and CPu, it calculate in the cpu the threads, and charge them in the memory to be sent to the Sound card , all this operation needs a good configuration, it depond of wish Memories you're using, and Don't use different memories, you have to buy them with the same frequency and Brand!
Do you believe that 1x512Mb memories are better than 1xGb memory with low Frequency, I tried it!!! and I understood that the processor need RealTime conversion of data threads with the RAM, if the Ram is slow, it'll wait until it finish its charging-emptying operations !
good luck!
peace. |

thanx everyone for the replys,
actually i use offline processing alot all my eq and comp are offline.
but acctually a weird thing happend, a track i made before i upgraded used no more then 380 ram and now after the upgrade it uses more then 600 ram,
is their any logical explenation for this?
because in both cases the track sounds fine. |

dj tuk, the amount of the ram won't surely affect how your song sounds.
You need ram (and harddisk) to store audio data such as tracks and samples. You need CPU power to process and generate that audio data, to calculate things like effects, eq and mixing.
If you're using a synth that generates the sound (such as Synth1, albino, v-station etc), you won't need much ram as the sound is generated in real-time. If you're using a synth that is based on samples (battery, atmosphere, stylus etc), you need ram more than cpu. Obviously this isn't this black and white in the reality, as some sample based synths also use effects that require cpu (battery with effects etc). Also some effects need memory too, for example delays need buffers to store the delayed signal (you can think it as an realtime sampling and playback).
There are ways to balance between ram and cpu. If you're short on cpu power, you can freeze tracks to make them almost completely ram dependent (audio is precalculated to one big sample). You can also trade ram for cpu by using synths instead of sample based plugins, but I think the cpu is the most precious resource there is, so i don't see reason to do this. How often have you ran out of ram instead of cpu power?
Note that if you freeze a track or have a recorded audio track, it isn't actually using the ram either, because the track would be quite big to fit in the ram and it can be easily streamed from the harddisk. If you freeze a vst that uses a lot of ram (such as huge choir/symphonic orchestra plugins), you actually trade ram for harddisk space so it's benefical too. And to make things even more complicated, some sample based plugins can even stream samples from the harddisk in the same fashion the audio/frozen tracks do making it unnecessary to freeze the vst.
So all in all, have enough ram to hold the samples and other audio data you need and place your bets to the cpu power and maybe a fast harddisk. If you're doing fine with 512MB but your cpu is choking, adding 512MB more won't help you at all - because you need cpu power!
