PCI-424 not compatible with Multicore CPU's?

[DJ Synchro]

Hi guys,

On the tech support site HERE I found the following sentence: PC motherboards that utilize dual-processors, hyperthreading, or 64-bit processing will also not likely work with the original 424 card.
I have a PCIX card which came with my MOTU 24I/O. My PC is equipped with a AMD Athlon X2 dualcore CPU and 4GB of RAM. Do I need to switch to the PCI-e card? I have major performance issues especially with Vista 32bit. Could this be the reason?
Any help is appreciated!

that was exactly my case too. my 2002 PCI 424 (not the X model) could not by no means be found by my 64x2 dual core Athlon. I work on XP 32bit Sp2. My motherboard has got 3 old PCI slots, the 424 fitted perfectly but not recognized by windows. I used all kinds of different drivers with no result at all.

Well, my Pc recognizes the card, and I can install it, however when I use Windows Vista, I cannot work with it, I get cracks and pops all over the place, and the CPU bounces back and forth between 80 and 100% even with small projects (I use Cubase sx for producing music) With XP it all works pretty good though... But sometimes the system loses the connection between the card and the 24I/O, then I have to start the MOTU PCI Audio console and refresh the settings...
I hope MOTU will write new drivers soon, because I really want it to work flawlessly on Vista.

ive just got a 424 card and a pair of 2408 mk2's and found a very similar problem mate i put a post a dsy or two ago. I'm running xp pro on a q6600 core 2 quad and a new asus p5kr motherboard. It works okay for a while, if a little cpu hungry, and then suddenly it will emit a high pitch sine and freeze up. I tried ndewest drivers, i tried differnt pci slot, i tried setting my DAW to only using one cpu core in the task manager section. Which actually helped free up say 10% of cpu, knocking it down from 70 to 60, (which is still way too high considering the small amount of channels and vst fx). I tried it this morning again, and alas, it froze up with the high pitch squeeel. KNocking the cpu reading to 99% constantly. Which means ihave to switch the whole pc off and turn the 2408's off and on too. Then its okay......... until it isn't again. Im jjust going to buy a pcie card. I think maybe you should too? You'd certainly benefit from the express' far greater bandwidth. (up to 32x the amount of the original 424 card apprently)

this is such a dissapointment though. Considering the fact that both motu systems i got (24i/o and 2408 mk3) work perfectly with my 6 year old Pentium 4 with the old PCI 424 of course. No drain of CPU,no drops, no problem at all. I wonder if motu did that on purpose, so that every body with a new Pc has to upgrade to PCI 424-e.

i know its a bi •••• that they dont just release a driver that suits a multi-core. I've been pondering for months and months over what soundcard to get and the motu's made the most sense for me as they are highly expandable and i have a fair bit of external hardware. Mostly synths, so needed lots of inputs. Well dissapointed that i cant get working on my tunes right away. 've got to get a better card. Got to laugh really.... i spent months deciding, then finally when i did, i overlooked the actual compatibiliy issues. I was too busy thinking about how many ins and outs id get for my money! Still. i cant wait go get the express card and really get going. Coming from a m-audio audiophile 192 with only one stereo input when i have so many hardware synths, i cant wait to utilize all the routing posibilties of having two 2408's! I can stop using the crappy behringer euromix 1 ive ben plugging everything into for years

Registered users of any MOTU PCI-324 or PCI-424 (x) core system can upgrade to the PCIe-424 card by visiting the MOTU Online Store.

Upgrade... right... You just have to pay for it, full price, no discount whatsoever. At my local shop it's cheaper...

[michaeldow]

yeah i noticed that there seems to be no incentive to actually getit from their store? And what's the deal with products that may already be registered? I bought mine off someone on ebay, he may have boughtit off someone else. Can i still reister or would i had to have bought it new?

If i buy a pcie card can i actually use it. Will i be able to get the drivers for it if im not registered?

[reeper]

try! Imean, its possible that he didnt reg´d it before you. Use the serialnumber on the unit. .

[michaeldow]

indeed you're right. Just didnt wanna have to take all the cables out if it wasnt going to work. Ill give it a shot

I'm pretty sure that it's only the original PCI-424 that may not be compatible with new motherboards and operating systems. If you have the PCIX-424, you should be fine. If the edge connector on your card has two slots cut into it, you have the PCIX version.

Pops and clicks can be caused by a few things. Misbehaving PCI cards are often to blame and some people find adjusting PCI latency can help. What other PCI cards do you have in your machine?

[michaeldow]

it is the original 424 yeah not the pci-x. The only other one in there is a graphics card. I've the 424 on all other pci slots and no luck. But it does say the orignal 424 may not work on newer pc#s so im guessing it's that. No biggie really, just a shame that with all the research i did, i overlooked that!

I think I have the PCIX version... But I'm not sure.
There is only a Graphics card situated in the PCI-e slot, nothing else. The thing is, that with Windows XP the performance is brilliant, so I guess it's a Vista + MOTU drivers thingy of some sort...
Which PCI latency settings do you recommend?

[michaeldow]

for latency, jst go as low as you can without it popping or clicking and using up to much CPU. If you dont use any hardware synths fx or dont record any guitars or vocals etc, you may aswell have the latency somewhere in the mids to highs as it will use up less cpu this way and wont really be affecting anything.
