ATI X800 PRO IRQ Issue's

creationite · Aug 15, 2005, 02:14 PM

Hello, I am fairly okay with technical aspects of my PC, however I need to admitt defeat and ask someone else in this issue as I have no idea.

I have two devices that appear to be sharing the same IRQ - 16

IRQ 16 - Radeon X800 Pro
IRQ 16 - VIA OHCI Compliant IEEE 1394 Host Controller

Both of the above have a status of "OK" within "System Information".

However I am having issue where during Battlefield 2 keeps randomly crashing and the only way to fix it is to press reset or a hard reboot, can anyone please tell me does this look like a IRQ shareing issue? or can these devices safely share the same IRQ? if I am best to change the IRQ of one of these devices, how do I do this? I have yet to assign a IRQ to a device.

thanks for looking.

The video card always shares an IRQ with something.

My 1st thoughts would be overheating?, bad system memory? bad or under powered PSU?.
Tell us your full system specs.... includeing PSU wattage / maker / model #

Have you loaded the latest video and chipset drivers? latest motherboard bios?
are you useing and 1394 devices? Are you haveinmg any troubles elsewere?

The video card doesn't necessarily always share and IRQ, it really depends on your motherboard.

Your BF2 issues could be just BF2, if you have this problem in other games I'd say it was hardware, but if its only BF2 then try checking around this forum for BF2 threads and see if you find anything there that helps

Other than that, I don't think its a major problem. If it was an IRQ resource issue then your system would be a LOT more unstable, period, so you might not need to worry.

Thanks to both of you for the speedy reply's. The PC specs are as follows :-

-------------------------------
System Information
-------------------------------
Operating System: Windows XP Professional (5.1, Build 2600) Service Pack 2 (2600.xpsp_sp2_gdr.050301-1519)

System Manufacturer: Part Packard Bell Part Custom
System Model: No idea
BIOS: BIOS Date: 02/09/04 17:35:10 Ver: 08.00.09
Processor: AMD Athlon(tm) 64 Processor 3000+, MMX, 3DNow, ~2.0GHz
Memory: 1022MB RAM
Page File: 263MB used, 3160MB available
DirectX Version: DirectX 9.0c (4.09.0000.0904)
DX Setup Parameters: Not found
Graphics Card: ATI X800 Pro

The Graphics Card has the latest catalyst drivers at the moment, however I have tried the omega drivers just to be sure it wasnt driver specific.

I dont really play other games but this crash however happenns in Eve Online. . . Hmmmmmmm I think there maybe a BIOS setting I am missing as there are 1 or 2 I dont know enough about in the BIOS to toggle on or off. I have tried to trouble shoot this for a bit now, I'm not sure what else it can be. I will get the couple of BIOS settings I am unsure about and if you could advised I would be much obliged.

I'd be happy to help

Do you have an IM client?

I'm one of those who has posted concerns about my video card sharing an IRQ with the USB 2.0. My system also assigns IRQ 16 to both. And, it's the first system that has caused me some grief in games.

One thing I did do that seems to help is to Disable the ASSIGN IRQ to USB feature in the BIOS. Without the IRQ assigned, I can still use the USB devices as needed. BUT, Morrowind seems to run MUCH better and for a lot longer with this setting.

The only other thing that I've posted about is the lost video sync that's happened both in 3D games and in Graphics apps. That, however, has happened only about 3 times over the past two weeks. Still, it's something I've posted about and would like to find a solution to it.

Yeah, my mobo's lan port doesn't work, I'm told because it shares the irq with the graphics card. It was suggested to me that I could manually assign the irq in some way that would sort the problem out, but I had a spare pci slot so I didn't look into it any further.

H3X4D3C1M4L · Aug 16, 2005, 06:05 PM

It shouldn't matter if its sharing an IRQ, the PCI spec is designed to share IRQ's.... only the ISA bus needs to have a single device per IRQ...
