PCI BUS Busy....

[Julian]

Hi everybody.

I am fustraded...

I just bought a new system to be able to edit HD and to get rid of the PCI BUS BUSY problem that we were facing here.

The problem:
Playing a 1hr video, Edius HQ codec or DV codec, 1 simple AV track only we always get that msg, and under other conditions too. But that is so basic...

We had a P4 2.8HT on a Asus P4C DLX, 2 gigs of Kingston KHX hi performance memory, 750g sata2 HD for video, ati9800pro video card.

And now to be able to edit HD and get rid of the problem we just put together a system with a PCI-X bus, an Asus P5NT-WS with a Core 2 Quad Q6600, 2 gigs of Ballistix PC2-8000, nVidia 8500GT pci-x16 video card and the PCI-X 64 bit bus for our Edius NX card. a 1.2TB raid 0 for video with 4 300G sata drives that gives 250MB/S on HD tach. Win XP Pro SP2. NO Overclocking!

What is my surprise... we are still getting the same msg... PCI BUS Busy. :(

Anybody have the same problem? any help for me?

Some things to look at:

1. Are you able to change the PCI lateny timer in the Bios? Usually it is set to 32, try 64 instead.

2. Does the video card have an exlusive IRQ?

3. Does the raid controller have an exclusive IRQ?

4. How many frames do you preload? Usually it's five frames, try 10 or 15.

5. Keep the bios up to date.

6. Set every value in the Bios related to speed and/or power management to standard or default values.

Thank you for your prompt answer :)

1. Are you able to change the PCI lateny timer in the Bios? Usually it is set to 32, try 64 instead.

I tried all latencies in Bios up to over 200

2. Does the video card have an exlusive IRQ?

No, in the new sytem the PCI-X and the old PCI share int 16 with more devices and I can't touch that it is a shared winXP IRQ, the funny thing is that there are INTs that are free in the system but WINXP pro doesn't allow me to change it.

3. Does the raid controller have an exclusive IRQ?

No they are all on int16


4. How many frames do you preload? Usually it's five frames, try 10 or 15.
you mean the buffers in Edius, they are at 96 edius maximum

5. Keep the bios up to date.
it is

6. Set every value in the Bios related to speed and/or power management to standard or default values.
they are.

he meant another setting, the buffer frames before playback starts, there are 3 choices, 5, 10, 15

also, is System Restore turned off on all drives? recommended

how many slots have cards inserted and what kind of cards?

[TonyB]

In the case of drive controllers, some controllers are known to be
greedy about bus usage, FastTrak in particular. Setting the PCI
Utilization to Low helps.
Try to DISABLE in BIOS.

In the case of network cards, disabling broadcasting protocols such
as NetBEUI and IPX/SPX can help. Disabling any network monitoring
utilities helps as well.

And finally, the preview overlay uses the PCI bus to transfer the
overlay image to the VGA card, so reducing the size of the overlay
or disabling it entirely will free up some bus time.

I meet the similar problem some days before.Then i reinstall the OS and solve the problem.

IRQ => it could be that your BIOS allows you to attribute an IRQ to a specific card

[Julian]

Thanks to everyboby for the help :)

I changed the buffers frames before playback to 15, we will test it today

[Julian]

About Re-installing the OS it is a clean install, fist week of the new computer, I just installed Win XP pro SP1 and applied SP2, disabled the automatic updates, firewall etc. this is an editing workstation only.

[Julian]

About changing the IRQ

The BIOS on the P5NT-WS does not allow me to do any IRQ changes it is all automatic. But I also was reading about shared IRQs and it seams that XP was designed to share IRQs that it handles that without suffering.

[antonsvideo]

once I know the answer to my original question, I can advise more

how many slots have cards inserted and what kind of cards?

[Julian]

There are only 2 cards

1) PCI-Ex16 nVidia 8500GT vga card

2) PCI-X Edius NX

Thank you

[T-Bone]

not likely to help, but turn off indexing on your raid drives

2) PCI-X Edius NX

Thank you

I searched the ASUS website for P5NT-WS and no results were found

could you provide a link to your mobo on ASUS website so I can see the slots, then I need to know which slots are free

did you but Edius NX without extension board????

[Mr Bill]

could you provide a link to your mobo on ASUS website


Hi Anton,

Found it for you.

Link 1 (http://au.asus.com/products.aspx?l1=3&l2=11&l3=485&l4=0&model=1529&modelmenu=1)

Link 2 (http://au.asus.com/products.aspx?l1=3&l2=11&l3=485&l4=0&model=1529&modelmenu=2)

[antonsvideo]

aha, the Australian Asus site has it

I went to the USA Asus site http://usa.asus.com/ and typing the model number in the product search produced 0 results

I am currently looking at the Bios config of this mobo and noticed that it is preset for PCI graphics card, be sure you change this to PCI-E if you are using a PCIe card

also, make sure hyper threading is on

what hard didks are you using for video capture and what speed do you get with diskspeed.exe (free at www.roadkil.net)

[Julian]

I am using 4 Maxtor 300gb sata drives as a Raid 0 drive that in HD Tach gives 250 mb/s I will try diskspeed later as the computer is editing now. I also have a 750Gb Sata II as a separate drive and 2x 250GB PATA drives as system C: and D: for data.

In bios it is set for PCI-E graphics cards as the primary card.

The CPU is a Core 2 Quad Q6600 and there is no Hyper Treading option that I know. I will check.

Thanks to everybody for the help :)

[Julian]

Attaching the results.

[antonsvideo]

the disk speed is sufficent, but low considering 4 drives in Raid0, are you sure the drive indexing service is off?

[Julian]

Well last night I left edius running over 12hrs playing in loop a 2hrs video that for sure was giving the PCI BUS Busy error and it played well no problems. I think that changing the preload to 15 did it.

As this is the 1st week of the new system if something happens in the future I will post it here.

Thank you very much to everyone that helped me :)
