I know it may be useless, but still, cant loose anything with trying.

I get bluescreens, one after another, after approx 20 min of use. Have the latest kyma version, and firmware on the Pacarana.

Everything works fine and dandy up to the actual block. I ran screens, dsp meter never reaches past 10%, ram roughly 30% and proc around 45%, all "full on" on the patches where bluescreens most frequently occur.

I have an i7 970 @3.2 ghz, 12 gb ddr3 ram, 250 GB SSD, konnekt24d for pacarana interface, and saffire pro 10 i/o for pc soundcard. Now most of the hardware besides soundcards is new. On my previous DAW, same soundcards, same setup and all, worked like a charm, no problems, with substantially lower specs. All drivers and firmware are up to date.

One of the weirder things I have noticed, the I/O delay options in Status window are unresposnive, I cannot change anything, it looks it is set on 10ms. Also the Saffire sometimes goes beserk, loosing and getting sync, restarting itself on its own, spooky stuff like that.

any tips to try, before I go for the full disk format and try from scratch ??

EDIT : I have windows 7, 64 bit, my kyma folder is in Program files x86

thanks for any input !

Whats bothering me is, that completely the same setup worked without flaws on my previous workstation. Thats whats making me hesitant to buy a new soundcard, because I fear it will only do the same problem.

After some searching, the ohci1394.sys file has apparently something to do with the firewire controller. And since this bluescreen is only recreatable via Kyma setup, that works on firewire, that is a hint.

Maybe the pacarana drivers ? 64 bit os ? fact that pacarana has fw 800 out and the rest of the components are fw 400, but then again if this were the case, previous workstation would have had issues too...gahhhh

It turned out that the asus mainboard "shared" the IRQ of the PCI-X firewire card somehow with my PCI-X NVIDIA GTX graphiccards through the whole PCI-X bus...
The standard PCI bus was not effected by this "sharing" and so i tried a cheap Exsys 1394 card with TI chipset and ... it fixed my problems.

For this "pc" workstation i recently bought a new board which handles the assignemnt of IRQs much better. With the gigabyte board i can use both together ... a PCI-X 1394B card in FW 800 mode exclusivly for pacarana-> Konnekt 24D and a 3 port PCI 1394b (FW800+400) card for 3 MOTU FW audiointerfaces on windows 7 or mac os x.

I do not think that you have a problem with your audio cards or your paca(rana). I think it is more a probem of you system configuration/setup.

Some questions i would ask myself:

What kind of firewire(1394) card do you use in your new setup?

onboard , PCI or PCI-X ?

(Onboard is most of the time a "no go".)

But if you have an onboard firewire port but use a PCI card...then disable the onboard FW port in the Bios.

Did the card/board came with a driver or a installer or is it supported directly by windows 7?
Did you use the latest drivers/bios?

Did you try to change the PCI (X) slot of your FW-Card and tried again?
On some boards it helps to pull out a card and boot once without it and then put it back in.
It then gets hopefully assigned a new adress... better is to change the slot...

Also some cards/mainboards come with a "installer cd" which may install old version of the ohci1394.sys.

For XP SP3 i remember there was a special topic at microsoft.com about this issue and a downloadable hotfix which was not included in the online updates.

I would like to clear up something, as I am a bit confused.

When you speak of onboard FW card, what do you mean with this ? The saffire 10 i/o that I use, is the main "soundcard" of my setup, and is plugged via FW400 to my firewire port on the pc. Konnekt 24D acts as a pacarana interface, and is connected to it via FW400-fw800 cable and on the other side connected to the saffire.

Could you be a bit more specific as to what should I disable in bios ??

thanks very much, and sorry for asking so much

I am talking about the firewire port of your computer.

Is it "onboard"? If it is near your USB and network port(s)
it is probably on the mainboard.

do you know the name of your mainboard?
(it is shown at boot time ... something like "Gigabyte GA-EP45-UD3LR" for example ...)

yes the firewire is next to the usb ports and it is embedded in the motherboard. Getting the name of it might be tricky, as I have a modified chipset in a laptop, that allows me to have desktop cpus and ram.

I have installed the latest service pack for win 7 64 bit, hope that will sort it out.

Besides that, do you have any advice, or workarounds about the motherboard fw port ? Can I buy something else (within sane price limits of course) to improve the situation ?

If you do not get the internal FW port to work correct with your audio cards you can buy an ExpressCard Firewire adapter (if it has a Expresscard slot of course).

My friends ThinkPad with crappy internal FW do not work "stable" with his FW Audio interfaces (Fireface 800, Traveller, 828, 003 Rack) but works great now with this one here: http://www.lacie.com/de/products/product.htm?id=10537

But I did not check the Lacie with the pacarana! Maybe someone from symbolic sound knows about a better Expresscard - FW adapter for PC.

I was wondering how to squeeze desktop RAMs or a CPU into a laptop and even despite from the fact that it is a power and heat nightmare like on most of the gaming laptops ...what would be the benefit? ;-)

Could be a driver, or memory issue or might be that overclocked processor.

posted 25 May 2011 08:20            

as for the laptop....its not hacked in the usual sense of the word. Its a set of desktop replacement models from Clevo laptop manufacturer. Nothing is overclocked, everything at default speeds. Its just, bigger

Im on the move a lot, so I decided ill try to go with something as much akin to a desktop powerhouse on the go, and until this little bsod hickup, I have had only great experiences.

well, bad news. bluescreen is back. Im really out of options I think, besides buying the firewire adapter that you linked Christian.

posted 27 May 2011 16:12            

Well ... i would try to install everything from scratch... after a backup of course ... and check that you do not install any unnecessary or outdated drivers...

Did you check the driver and FW chipset of your laptop? It should be possible to identify the FW-Chipset by the manufacturer ..

If it is not a TI-Chipset then it is probably a good idea to buy the Express card ...

all the best

Yes Christian, I have confirmed with the manufacturer, it is a Ti chipset.

Id like to try this. It sounds similar to the last setup in this list, although I will need to buy an additional FW 800-800 cable :
http://www.symbolicsound.com/cgi-bin/bin/view/Learn/ExamplePacaranaSetups

Until then, I am connected : laptop -FW400- konnekt24d -FW400-800- Pacarana

no crashes or bluescreens as of yet, but I cannot select anything in the DSP window, only silent device. No sound output, but sound is generated, I can see meters flashing in the dsp window.
