serious problem with cpu overload

ARCADIOS · Post by **ARCADIOS** » Thu Jan 05, 2006 2:41 pm

i work on a project in nuendo sending 24 asio2 channels to stm2448 mixer in scope.
i control the channels from scopes mixer.
cpu load goes up to 60, 70, 80%.
i tryied to disable some effects in nuendo and put some other in scope to use some dsp power.
but there is a strange cut of the hard disc that occurs when the music is playing.
the hard disc makes a small sound like very small beep, and cpu on task manager shows 100% and and then the small pause happens. it pauses the sound and the mouse pointer as well, and the music is heard like a trembling. the pause lasts for half a second(not always the same... sometimes one second) and the distance among pauses differs.
i see that when the project is a little more loaded these pauses happen more easily.
I CANNOT WORK
HELPPPPPPPPPPPPPPPPLEASE

I bet your system tries to tell you that you overdemand it...

a little more specific?
at the moment i try not to use page file cause i have 2gigs.

may be you have some heavy delaying and reverbs going on? These use PCI busses.
if your Nuendo project also is heavy loaded (80%) it could be too much.

What is the power of your machine, Scope cards, and how many audio channels and plugins are you using? It is difficult to picture anything without this basic information first. Tell us please.

scope pro+pulsar2 20dsps
abit ic7g, prescott 3.0
xp sp1a. standard pc.
2gigs of ram
1. seagate 120g for tests.
2. raptor 10000rpm for audio only.
3.virtual memory on a 2nd raptor.
4.300gigs maxtor for storage of projects.
raptors are on ichr5 controller
the other two drives are on 2112sillicon.
bios irqs manually and no irq sharring i think.

i use asio2fit64 source and give to asio2 dest through bus 1,2.

if there is nothing that i can do except than buying another pc, please tell me how do you work and which is the smartest way to optimize the system and to work like?

i use 24 channels and it is difficult to use less than 17, 18.
all given through asio2 on scopes mixer.

sounds like that drive is quickly dying. look in the device manager, is ide in pio mode? if you disconnect that drive, does your system work properly? 24 channels of asio should be no problem with a healthy system.

Also I time ago problem overhead cpu bat only with pci bus band large usage (big scope proget)and many VSTi plugins open,I have optimize Win XP to the max using for DAW and kill other fature of OS using,XPLITE,xsetup v6 and optimizing w xp drivers and hardware and service (90%) unnecessary,pherars your problem is it one driver (soft or harware) or appz that make your cpu in OVERHEADS,after optmizazion for me one big proget that pre optimizaziona have 70 % of cpu time now have 40-50 % of cpu time,Try to remove uneccessary drivers(cpu fan monitoring and your relative driver SMBUS)and other unnecessary app and driver,make sure tou have the last bios and chip set drivers installed,make sure that your BIOS setting are correctly,try to assign different line of IRq to your scope cards.set cpu usage for backgroung drivers and no to application,try to set in your bios PCI latency time to up superior values

sorry for my bad english

Could be this?

holy moly arcadios, that's a lot of drives. Does it sound like a 747 passenger jet ?

Sorry to say it, but as much as I agree with the suggestions given to you here already, the first thing I'd do is drop back to 2 hard disks. I don't see any need whatsoever to run 4 HDs when you could just partition 2 drives into 8 or 10. Use a secondary partition on your system drive for tests (presumably you mean testing software installs) and obvioulsy use the biggest, fastest of the 2 drives for HD recording. A third drive if you really need it at some point perhaps, but a 4 HD Daw is just OTT & asking for trouble. (not to mention noisy I bet)

Also worth asking what you're doing network wise. I'd rather keep a Daw 'UNPLUGGED' from any network. CDs, DVDs, Portable USB HDs & pendrives are all good for trnsferring files to and from your Daw the stable & safe way.

Nestor · Post by **Nestor** » Fri Jan 06, 2006 5:49 am

If a system is properly configured, there are no problems in having 4 drives. I habe been working for a long time with 4 drives.

Shroomz~> · Post by **Shroomz~>** » Fri Jan 06, 2006 6:01 am

Nestor, I'm not saying four drives won't work, but in a Daw? Mostly I'd say it'd be too noisy unless you've got super silent everything & an expensive case & even then, drive arrays are meant for server applications. There shouldn't be any need to have more than 2 drives in a Daw. Just an opinion though

dbmac · Post by **dbmac** » Fri Jan 06, 2006 7:08 am

Anyone running BFD or a similar disk streaming library probably has a designated drive for it. So a 3 drive system (OS - Audio - Drum samples) is pretty common. If you also have a (non drum) sample library, this will have its own drive. I've been running four HDs for years.
The new Seagates are very quiet.

In my system, today with 3 drives, two IDE and one SATA, the noise is more than acceptable, specially now with the WD Caviar SATA 160, which is so quiet that I need to stik my head onto the case to hear it.

As said here, three drives are today very common. Of course, the best would be to get a comple 500GB instead.

Herr Voigt · Post by **Herr Voigt** » Fri Jan 06, 2006 2:39 pm

I've heard, the very biggest HDs are noisy, hot and have a shorter life. For my DAW I would not take HDs bigger than 250 GB.

astroman · Post by **astroman** » Fri Jan 06, 2006 5:33 pm

aside from rotation speed (obvious), it's the number of platters that are responsible for heat.
A 'regular' 250 GB gets damn hot already.

cheers, Tom

Nestor · Post by **Nestor** » Fri Jan 06, 2006 9:14 pm

I think you are a bit updated, as HDD are changing all the time. I have a Western Digital SATA Caviar 160GBs, and is THE COLDEST hard drive I ever had. I am not exageratin. If you touch any of the three drives, the other two, after working for a while, get quite hot, while the WD is unviliebable cold.

The SATA drives from WD have a special technology for this, and it works, hot and big drives are slowly going to history

astroman · Post by **astroman** » Sat Jan 07, 2006 3:23 am

... but are still sold

the Caviar you mention is certainly a 'new' one, as WDs have not been particulary quiet in my experience - it's good to read that things improve.
As mentioned, the number of surfaces of the disk is responsible for heat emission.
Less platters with higher density also improve transfer rate - it requires a more sophisticated read/write electronics, tho.

cheers, tom

Your right Astro, the drive has two months of existence.
