Hi all - Can I ask for some help in here ?

I mentioned it in between the lines elsewhere, but my new system turned out to be a fiasco;

Motherboard : Asus P7P55D-E Evo (s1156 socket)
Processor : Intel Core i7-870, 2.93GHz.
All SATA drives configured as IDE (no AHCI).
OS on a OCZ Vertex-2 90GB.

This small set brings nothing but distortion. The best what may happen is that I have4-5 minutes of normal sound (which still sounds wrong to me), and then slowly the distortion starts. It's small ticks in the beginning, but it is a matter of waiting until completely no music is audible anymore.
Whatever Q settings do not matter a thing, as does the sound engine;
The strange thing is : this happens the same with KS Adaptive mode which checks the buffers, and no error comes from that. So, somewhere deep down things seem to get out of sync, while the OS doesn't know about it (buffer checking).
Oh, Split File Size influences largely, but never brings a solution.

Disk light flickers each 1 second, and as far as I can see it doesn't come from some OS settings. Notice that the exact same OS (disk) put in my old system, doesn't exhibit this, nor is there distortion.
W7 or Vista no difference (clean installs). With and without Tweaked to Dead.

I am not going to ask you what this can be, nor am I able to try suggestions (the PC is out of order now, and all is in the old system again), BUT, someone may have experienced the exact same. Also, I recall a post/topic somewhere told about a similar thing, but don't know where to look for or how to find it.

So, the most characteristic is the vinyl-like ticks it starts with, which grow more and more and more, eventually ending up in distortion only.
Once the distortion is there, it is clearly noticeable that e.g. a moving graph from TaskManager incurs for the distortion (gggk gggk gggk).

I tried and switched etc. all I could think of, but it all doesn't matter a single bit. The only thing I did not try (I didn't see how to do it) is changing the FSB/Clock ratio which is set to 22, and which seems high to me (more normal would be 9 ? -> I just don't know).

It feels like PCI bus related.

If anyone even had the slightest problem which looks like this, please let me now !
Thanks for your possible help !
Peter


PS: Actually for me it is a bummer only, and not much of a problem; I will trade the lot for something completely different, and 99% sure the problem will have gone. The importance is though, it may happen to you the same. So I rather "know" what causes this, and how to solve it.

Hi Johan,

I have worked for about a year with this fine card. On Vista. With the early Beta driver .978.
But after switching to W7 64bits ult. and the latest HD2driver 1.08 the fun is over. After the first restart I get beautiful BSOD's. Problem is only gone after un-installing of the driver and installing my second card, Asus Essence ST, with its drivers and I am back in business.
But NO Quad Arc Prediction, just two times works(with ticks)! Using SPDIF out. This is because of the restriction of the missing sample freq. as 88.2 and  176.4.on the Asus card.
When using the built-in dac of the card with the anal. outs I can do all the tricks because the card itselves resamples in that case.
But that is not what I always want. I want to use my seperate dacs as well! That means dig. out!
So, problems should be gone when using the HD2-dig out, because this cards does everything between 44.1 and 192-16/24bits!
Can you tell me how you get your card working on w7 ult. 64bits(or is it 32bits?). What driver do you use?
Hope you can help ,

Ed

Hi Ivo,

I'm using filtered battery power with all electronic components (Except the pc -- at the moment ) and all I can say: There is a big difference between this system and conventional power supplies, it's worth the effort to optimize.
