DZ87KLT-75K Issues



Hi all,

My pc is around 1 week old and has been working fine except for the memory issue discussed elsewhere. However I realized the bios was not reading the clock speed of the CPU correctly so I reloaded to bios defaults, this fixed this. So i then setup the settings to how they were before the bios reset and now my pc has developed a few big problems.

I now cannot use my mechanical keyboard, it just locks up and will not work, i have tried several usb ports with no luck at all. It does work okay in my brothers pc so it is not the keyboard.

2nd issue is now when there is sound playing i get really bad pop and crackling effects and this is made even worse when sli is enabled. Still get excellent gfx performance but this is no good when the sound is unbearable.

I have tried reloading bios, drivers and this has made no difference at all. I do not think reloading windows would fix this either. It's a fresh install and was working fine until I reloaded the bios.

Is this a sign of the board going faulty or is it something that could be fixable in a future bios revision ? Any ideas guys ?

Many Thanks

Try removing your SoundBlaster ZXR then reload BIOS to default, then after try setting the BIOS to whichever values you want all without the SoundBlaster ZXR and see if this helps.


Daniel82, please follow the suggestion given by stephenb.b.r and let us know the results.

In addition to that you can try removing the CMOS battery and leave the system without it for about an hour. Then, put it back on and restart the computer.


Thanks for the help Stephen and Sylvia,

I tried both of your suggestions and also tried the card in different pcix slots and still the issue persisted. I have since swapped to a asus sabertooth board and this has resolved my issues. Also it resolved an issue where on the intel board I had no rpm fan speeds reported (using corsair AF & SP fans) I now have these being reported with the asus board.

Shame as I think the intel board had slightly smoother performance with sli enabled. So yes this does appear to be a faulty board. Thanks again for your help.
