XXHighEnd

Since I received my new NOS1, I have been switching between W7 and W8. The reason for it is that I "heard" lots of people raving about how W8 sounds and that it was way better than W7. That was the only reason why I got a licence for W8 (and it was cheap to upgrade also).

But yes, the differences I heard between them pushed me back to W7, but I was late compared to many colleagues here, because of the addition of the NOS1, that is, by the way, a wonderful one. XXHighEnd + the NOS1 have pushed things to a direction I would never imagine to turn that deep.

So, since I was discovering this addition, I did not care too much about checking other things.

So I was quite surprised to see that I can't "quiet" the CPU cores, at least for the one(s)  used to play the music.

Among the settings, I first disabled all I could (PA, XTweaks, normalization), to reduce the variables in the equation. I even reinstalled a backup from W7 to eliminate the potential "alterations" I could have done that would induce a negative result (sometimes, too much of something can have an adverse effect).

I use whatever tools that I know (there are surely others) to help me in my quest for a quieter PC: DPC Latenty Checker from Thesycon, LatencyMon from Respledence Software and of course the Task Manager -> Performance tab . I even went in the BIOS to reduce the ram speed (from 2133mhz "XMP" state that overclocks the CPU) back to its standard 1333mhz ram speed.

Before having this pc, I had 2 others: am old laptop with a 1.6ghz dual core CPU + 4GB ram with W7 pro (64 bit), also a Lenovo with a G620 dual core (2.6ghz) - each of them with the same exact OS properties. I was able to get at least one quiet CPU core for the music.

Now I have an Intel 3930k CPU 6 + 6 cores (hyperthreaded) but I can't seem to get at least one to stay "quiet" and it eludes me...

I deactivated all the USB 3 ports from it just to check, even the Sotm USB 3 PCIex with which I had so many problems before (was generating blue screens with my previous Audiophilleo - Bryston configuration), but not anymore with the NOS1. I plugged the NOS1 through the motherboard USB 2 ports (Intel), but it does not change a thing.

There is a pulse each 60 seconds on all cores with the DPC Latency Check and the driver that seems to induce the latency is the Phasure NOS1 driver itself... I got the 1.03 version for W8 that also works for W7. I don't know if this was happening with the previous driver version or not, but I don't have it.

I have tries the most "relaxed" adjustments from XXHighEnd, but I haven't been able to overcome this situation. Maybe it is normal, maybe it is something with my motherboard (ASUS Sabertooth X79 with lga 2011 socket), or something obvious I don't see, but it seems annoying for me to have such a powerful pc without a way to get at least one or two quiet cores.

Not that I don't like what I hear, but...

Is there something I haven't thought of ? The answer seems obvious, but at this point, I have changed the Q1 between 3 and 30, SFS between 2 and 430, clock resolution between 5 and 15ms...

Thanks :)

Alain,

To me it seems that all is a matter of paying better attention. Remember, *seems* ...

For now we can stick to one subject only :
You say you see a spike on all cores once per 60 seconds. In the mean time you say you tried all kind of variations and gave examples of them. Now, no way those spikes once per 60 seconds will tay the same, OR you forget to mention other spikes. When the latter, the former is strange indeed, but I merely think you forget to tell that those 60 second spike intervals can very a lot (on those interval) with you changing those settings.

Or ?

PS: I tried not to miss it, but with which OS is this ?

PPS: It can't harm to post pictures of your CPU graph. But tell with what settings that occurs. Then I can try to explain (or see something wrong ! :) :))

Yes, I thought about that... And I forgot to mention the NOS1 buffers (between 8 and 12ms)...
I will send the different graphs back from work... And better organize my thoughts as I did not read myself enough before sending my post...

I am very conscient that there are so many parameters that could explain this... Normally I am persistent enough to avoid this, but this time it really eludes me...

It is with W7 by the way...

Thanks :)

Alain

Well, finally after reinstalling W7 and without doing any updates (from Windows Update), all is back as it should. Almost all the cores are quiet and the DPC Latency Checker does not show anyhing odd anymore :)

Alain

Did you update to sp1, or are you saying you're staying with plain Win 7 ?

Hi SeVeReD,

Thanks for noticing that my sig is not up to date. In fact, the version I use is W7 Pro x64 SP1 (the installation DVD). I am updating my sig.

Regards,

Alain
