ga-x58a-ud3r REV 2.0 SLI/Sound issues

[Guradem]

Hi all,

I am having a sound issue with my new ga-x58a-ud3r REV 2.0 mobo. I keep getting a constant clicking noise and slowing down of sound whenever I use a audio application like spotify or watch a move on you tube but only when i have SLI enabled. It happens with both the on-bored sound card and a spare PCI SB card i have in fact it is much worse with the PCI sound card. Dose anyone have any ideas what might me causing this as I have already tried the following:

Tried a different set of Headphones
Updated Sound card, chipset, SATA, Raid and ATAPI drivers
Tried various BIOS versions (FA11,16,18 Fc1)
Added sound playing applications to MS Security essentials exception list
Changed MS Security essentials to a completely different VS
Turned off power saver options in BIOS (CE1)
Turn off W7 indexing & Areo
Tried the GFX cards in different PCI/E slots.
New PSU and Electrical ring (with a UPS as well)

My system spec is as follows.

Try downloading and then running DPC Latency Checker from: http://www.thesycon.de/deu/latency_check.shtml
and then continue to do your normal things, then check the graph and see if you have any red bars. If you do it is down to a latency problem.

That is the first thing I did and am showing steady green feed,  it is not caused by any form of software latency. TBH I am beginning to regret buying the damn thing as half the post on the board seem to be about it

The only other thing that springs to mind is that it is to do with bandwidth on the PCIE bus as it only happens when SLI is enabled.

That is kind of what I thought but surly it cant be a hardware limitation ? I've had vastly crappier boards than this without any issues.

Did you run the "vastly crappier boards" with your two SLI graphics cards though?
What PSU are you running? It will need to be at least 1000W for your hardware and a decent one at that.

Yes and I have a 1000w psu.

As long as it is fairly new it should be fine. Bang goes another theory.

Do you have any warning signs in Device Manager?

Nope I am obsessive about  upto date drivers/firmware/BIOS and there seem to be no resource conflicts, hell I have even tried different codec packs.

Well I really can't think of anything else so I would advise you to contact "runn3R" the Gigabyte Admin of the site and arrange a RMA of the board. It must be faulty.
