MSI Gives Liquid Cooling to its N285GTX Hydrogen OC
The new N285GTX Hydrogen OC from MSI features water-coolingMSI has added another GeForce GTX card to its portfolio – the water-cooled N285GTX Hydrogen OC. The card is equipped with a water-block that MSI claims gives its quieter, cooler and faster performance.
Targeted at the enthusiast crowd, the new card slots in beside MSI’s custom-cooled N285GTX SuperPipe OC and features a lathe-processed sub-millimetre-sized copper water-block. The block gives the card a 40% reduction in temperatures compared to stock air-cooled ones.
MSI has also thrown in some overclocking to make its card more attractive – the N285GTX Hydrogen OC has been pre-overclocked at 702MHz for the GPU, while the 1GB DDR3 memory has been overclocked at 2,600MHz. The single-slot design of the card makes it an ideal companion to three-way SLI setups. Making the card compatible with existing water-cooled systems, MSI has provided a water tank pipe thread that is based on the G1/4 Inch (DIN ISO 228-1) standard.
MSI is expected to price the card around £390, making it a pricey one. While price can be a setback, the company is banking on the belief that enthusiasts would definitely want to own the world’s fastest single GPU that has been pre-overclocked and comes with liquid cooling.

Some thoughts that I couldn't see others have suggested:

Do you have a soundcard as well as an onboard soundchip and are they both enabled?
Nope, crosshair supply a card - no onboard siound

Have you recently updated your BIOS as loaded different settings for an onboard chip?
Nope, I have reset the cmos as well. No difference

Have you tried running dxdiag, in particular the sound tests for the various audio formats and making sure hardware acceleration is fully on?
Good idea, will try it

Does device manager show any resource conflicts for your sound controller?
Nope its all fine there.

I've come across all of these when these with dealing with sound conflicts

Well I had sent my ram off and so was using some memory from my dads pc.
1 2 gig stick of 533mhz - I think thats the speed. - There were no problem playing music then.
Get some new sticks back from RMA.
The stutterings back.

Must be the motherboard.
Had new HDD
audio is external but comes with mobo.

U got cool'n'quiet on in the bios ?

I don't know if you fixed the problem yet, but I think that you need to change the IRQ of the sound card a few times in BIOS. Right now you have it on AUTO, and it shares it with some heavy I/O device that has higher priority in the queue then your sound card would have, you just have to look at post time what IRQ the sound card got, and change that to some other number. You might have to try a few times, until you find an IRQ that's not so crowded with so many I/O requests.

Sihastru, thanks for the piece of information.
How do I do this? I have taken a look in the bios. I have a setting for plun n pray OS or not.

Plus manual and auto for IRQ resources. If I change it to manual I am able to reserve a channel.
But I cant find out how to set it to something, ie the sound card.

Why would this suddenly happen?

13-08-2009, 13:35:42

Well it's not as simple as it sounds.

In order to view the actual IRQ your soundcard is using, you must go into the Device Manager and select in the main top menu View -> Resources by connection.

Now if you're not familiar with how a PC works, the data displayed might be confusing. Just open the Interrupt Request (IRQ) node. There will be A LOT of (ISA) some number entries. Scroll down until you reach (PCI) some number devices.

The some number is the actual IRQ number. The sound card will most probably be listed as High Definition Audio Controller. Make a note of the IRQ number. Also make a note of what devices share the IRQ with the sound device.

It is not yet possible to change the IRQ values. The problem is that your motherboard is ACPI and PnP compliant. This means that the OS or/and the devices (this is what means to have a PnP device) are negotiating with the BIOS to get the IRQ numbers.

Right click on the audio device entry and choose Properties. There will be a Resources tab. In this tab you'll see more then just the IRQ. You might also see a Memory Range and other stuff. What you're interested is the IRQ in that list.

If ACPI and PnP is enabled in BIOS, then the Change Setting... button will be disabled, and Use automatic settings will be checked (and also disabled).

What you need to do now is go into the BIOS and change the PnP value to Disabled or OFF. Not sure how it is in your BIOS. ACPI also has some influence on the settings but don't change the ACPI setting. If you do your operating system might not boot anymore (BSOD at boot)! You've been warned.

Now some motherboards allow you to change the IRQ values in the BIOS, but even if they do, the OS will override the settings (in most cases that's what's going to happen, not sure if your case is one of them).

The IRQ's are in the section with the option Resources Controlled By.... Different BIOSes have this in Power Options, others in the Advanced Configuration, don't know where yours will be exactly but it's not that hard to find. Change this setting to Manual.

Now you should be able to change the IRQ values in the BIOS. We don't know if they will stick once the OS is running. If you can't change the settings in the BIOS, just go in the OS, in Device Manager and follow the steps you did before. See if the Change Setting... button is now active. If it's not, you'll have to change the ACPI setting in the BIOS but this most likely will result in a BSOD.

If it does you're on your own. Sorry. Hopefully PnP and Resources Controlled By... will be enough.

If the Change Setting... button is active, you can go ahead and try different settings for the IRQ. Which one to use, I have no idea, you'll have to experiment. In my system, it is 22 and it is alone on that IRQ, and it doesn't skip one bit, even if I set it to 192KHz, 24bit. in the driver.

Hope this helps.

Disabled pnp but couldnt change the IRQ value.
the HDDs are on the same channle. Tried moving them but that didnt seem to do anything.

Hi :)

Could this be a bandwidth problem if you are streaming the music? you have alot of other downloads running at the same time?

Also if you have task manager running well playing the music when it stutters u would be able to see if a service or process is spiking and eatting all your cpu/memory.

Good Luck :)

Nope done that bit and there is nothing unusual. It happens throughout the day so wont be a bandwidth issue. Plus when I am playing from HDD.

Well, I also said about the "Resources Controlled By" setting that should be changed to "Manual" not only the "PnP" setting. When you change the setting new options are exposed, a new submenu appears, where you should have the IRQ list. On the right side of the BIOS screen there will be explanations about what devices are using a certain IRQ when you browse though them. Also a section with a bunch of INT numbers might appear.

So what exactly can't you actually change? On every BIOS I can enter I have these options. And you do have an Asus board, so if you can't get these options, you haven't followed my instructions correctly.
