Hi,
I have a pc running on a AMD 3500 64 bits socket 939, which is a very fast processor.My pc has 1 Gb ram memory dual channel 400 Hz. As I ve been using some heavy vstis such as stylus rmx and trilogy plus some other synths, my cpu began overloading.
My doubt is:
if I upgrade my ram memory to 3 Gb will it avoid CPU overload or is it a matter of processor upgrade??

hey,
i had the same problem,
i couldnt even load 2 synths...
it was the temperature of the cpu..check it
i dont belive thats the cpu and ram...with
ur setup u should be able to run alot of vsts..
but maybe i am wrong...good luck |

Too much feedbacks..i think
try to close some delay,reverb....
i think it will get better.. |

Kasmakaja and Zaki,
of course i m using a large amount of vsti and plug ins and tht s why I have ben in trouble. But I garantee that if I had a mac g5 dual core Intel with 2 Gb ram it wouldn t be a problem at all. I wonder if the processor or the ram amount would be the main solution in this case... But My question has not been answered:
I want to know if I enhance my ram memory will my CPU meter in cubase show a lower cpu load compared to my ovreload problem that i get sometimes.
About temperature I don t bother, I have a big Zalman cooler that makes my cpu freeze no matter how much I use it... |

as soon as you use alot of different vst/vstfx you're opening the door wide open for performance problems. especially if you use lots of old and free plugins (nothing against free !!!) it's often dangerous because of unpolished, buggy software. denormalisation is one of those problems. A good test of your performance would be a vst you know works rocksteady. open up some instances of it and use some quality reverbs.
see if you can max out your cpu and how many instances it takes. I bet you get different results.
if you can isolate the plugin that takes up much of your ressources, just use it as an offline process. another solution is to choose alternative plugins that tend to work flawless, or simply update old plugins.
to your question: does your car drive faster when you install a cd changer? nope, it's just more pleasant to drive with!  hehe nah jokes aside, your cpu load won't reduce magically because of more ram. it will help in sample heavy enviroments like stylus rmx, samplers etc. realtime stuff like low latency asio won't benefit largely from upgrading ram.

Ok sidefx,
so your opinion is that for an overloaded cpu on a certain track it would make no performance diference if I doubled my ram memory..right?
I know all the solutions to lower cpu loads such as freezing tracks and working offline.
I just needed to know if the ram upgrade would bring me any benefit to be able to go further using plugins as i wish....cause as I said in a G5 dual core I could do more than I ve been doing for sure. So I was concerned if trhe diference between my pc and a G5 would be only on the processor itself or also in the ram memory amount.. |

socket 939 with which chipset? do you have (and use) a pci express gfx card (or other devices on this bus)? |

can anyone list this solutions to save cpu while working with vsts on cubase ??
of course heat pisses off, and i sometimes have to switch off, so i guess this is not such a good solution, do you know any other cpu saving trick??

if you have problems with trilogy probably it's because of your ram and not your cpu. trilogy eats a lot of ram but doesn't eat much cpu. |

ess765: I definately think you should be able to open lots of vst's. something like in the 10-20 ish. I recommend you to check irq settings (keep graficcard and soundcard on a seperate irq) and the dma settings of your chipset/harddrive. reassure that you've optimized windows for background tasks (asio is a background device if I'm not wrong)
further on download the tool enditall2 (free). with this tool end all unused processes that you won't need for audio. be sure to use this tool with caution.
check your pc for spyware, trojans, viruses.
if nforce4 chipset, try a different pci express graficcard, something really cheap (ati x1000 or even lower spec).
disable power saving in your bios if available (let windows handle it)
you could have problems with your acpi setting. attention: different oppinions exist. lots of soundcard companies tell you to disable acpi, involved with a reinstallation of xp.
keep me posted, I've got some more ideas.

zafer: okay here some ideas to reduce cpu load.
for designing melodies, take a good vst with low cpu usage. build your midi tracks with this synth. This gets useful if you're really out of juice with your cpu. when done, use your fullblown preset with your favourite synth.
disable unison, number of voices etc. While lots of synths and presetbased setups always dial in alot of polyphon voices, reduce them to 1. basically as if you want to use a monosynth. also check the quality setting in your vst. Lots of them have oversampling against aliasing. You won't need that in the beginning and later on, simply activate those things again.
disable fx units on your vst. Delay and Reverbs built in your instruments often use a fair amount of your ressources. You can always add delay and reverb at a later stage, and you won't be able to get rid of such effects after bouncing. Rather use fx channels or however they're called in your host. Sometimes you can share such effects like reverb, delay, filters etc for several synths/tracks.
bouncing/freezing
I tend to never freeze parts. In my host they're unmovable after that process. So either use the bounce function of your host (you guessed already) or simply use a recorder tool
voxengo recorder
silverspike 1 & 2 (my favourite)
these tools let you bounce things quick. Also think of bouncing as a fresh start for new processes. Some of them are very easy to achieve in audio. Like reversing single notes, pitchshifting, clean crossfades and and and. you also can load these parts in your favourite sampler and use its magic with your bounced parts.
other solutions for two computers:
vst system link (steinberg)
Plex wormhole
fx-teleport (my favourite)
midi over lan
buy a soundcard with a dedicated dsp on it. I havent got one but I hear they're awesome. And they use almost no cpu. If you happen to have an old creative audigy1/2 soundcard, you could always use kxproject drivers. These drivers allow to use the onboard dsp for reverb and other fx. you can set them up in your host as send channels. They won't use any cpu. The quality of these dsp effects isn't top notch, but you always have the possibility to exchange them with quality ones later on.
Also check out projects that plan to use your graficcards gpu as an audio dsp. (http://www.bionicfx.com/info.html). I've seen news that a similar project is planned for ati hardware. so much for the future.

Increase the latency (ASIO buffer). Unless you are playing along with a MIDI keyboard, there is absolutely no need to have low latency. This can have a major impact on how many VSTs you can run.

Yes Undertow..that might be a option but I use a midi keyboard to record riffs..although I ve been having a different latency problem that maybe be you could explain me better:
when I record I listen to what I play in real time and feel no latency at all. But the recorded midi clip always delays a little..so I have to go to the key editor and quantize my recorded notes....do you have any idea of what could be made to solve this?? |

ess765:
most likely I know the solution to your problem.
check out your cubase folder. there should be a directory called midi port enabler. Read the pdf, on page 2 is what you search.
Basically create a file called ignoreportfilter.* and erase the data extension.
Back in cubase you'll have now the option to choose not emulated midi ports.
Hope that helps.
