Resource Conflicts!

[techmanc]

Well I always think of these as a IRQ conflicts/resource conflict. I believe they are caused by using too many peripherals and running out of system resources. I a lot of system I have built the problem is obtained as the maximum amount of hard drive/optical drive controller/ controller card with a high end audio card like Soundblaster series are used.You know you have these conflicts when drives and drive performance will be slow when coping file HD to HD or using burning software. Sound cards and graphic that stutter. Its a lot better with SATA motherboards as it doesn't need to deal with master/slave type of problems unless you using ide devices.

Anyway for these types of problems anyone found software solution that can show which devices are conflicting to be able to goto the device and try to resolve there conflict? Also How do you troubleshoot/classify these problems?

I know in BIOS shut of all non needed peripherials like com and parrell ports, sound card and midi, firewire, ide, network will reduce resources used. Sometimes switching a card position in the motherboard will help if you have another open spot.

I am hoping in this thread I can some help to making these type of problems more easily resolved.

Heres a link to an old but good thread on ide controller issues I post on CDFreaks awhile ago if and need help in that area..............

For what it is worth, if the drivers you are using were written well, then nobody should have any IRQ conflicts. The resource conflicts are also the result of crappy drivers 95% of the time.

For checking IRQs & conflicts/sharing, just run Msinfo32.exe, and under the hardware resources, there are entries for that. Don't freak out if they are sharing IRQs either, that is normal, and does *NOT* mean you are going to have issues. The only time you will have issues is with bad drivers.

I been using msinfo to check for problems but its not reliable.
As a matter of fact I was testing the information found there now to see how useful it is. Now its tell me i have a lot of conflicts but my main concern was the conflict between my video card and SATA controller which show them using the same IRQ16. After installing controller in a different slot on motherboard the results are the same. Heres some msinfo information to show what I mean.

Having the same virtual IRQ is OK.
Unless you have a non-ACPI system, then don't worry about what it shows, and it is perfectly fine.

Like I said, the only time it isn't fine is if the driver for one of those things isn't playing by the rules, and is hogging all resources.
For the most part, WHQL drivers mean that the drivers are following the rules. (Though, not being WHQL doesn't mean they aren't following the rules either).

You can move the card to whatever slot, and most of the time, it will still show the same virtual IRQ, but what is really going on 'behind the scenes' is a different story, and isn't really worth it to get into.

I dont worry about it my point is not a good method of finding out a if there a problem because it only useful if/when it actually a problem with my system. The pont of this thread is I know a lot of people are suffering with resource and IRQ problems more on the former IMO and there no good and accurate way to see/find them.

Oh, I understand that, but, IRQ/resource issues on any ACPI system is *very* rare. I just think people will freak out when they see a bunch of (virtual) IRQs being used for many different devices, and they will try changing IRQs manually, which they should *not* do, since it is *not* a issue for the vast majority of the people.

If you have ancient hardware (with those craptastic drivers), then, that is about the only time you should manually assign IRQs, but it would be FAR better to throw that crap away.

Take a look at my sig and I and you can see the hardware I use currently. I gave up trying to use my Audigy Extreme Gamer as it wouldn't' play well will my system always having intermittent with hard drive crashes - stuttering sound - and my burning software would fail. I know most people start out with no problems and stay that was if there not adding peripherals. But as soon as the start adding more devices there getting a better chance to get a conflict without really noticing any problems. But if they use a combo of devices eg gaming taking full use of sound and video card the get different conflict issues and lie me stating playing with different setups with there hardware and software/drivers. How do we find out device are now actually causing the conflict?

The people using a few devices once there setup will most likely never have a problem as plug and pray covers them.

Ah well I was hoping there would have been more discussion on this. I guess no one having any conflicts with there system.
