I cannot see any difference (on my PC) in CPU loading with USB2 or USB3 running they both look as far as I can tell exactly the same. Basically CPU runs at 0% with occasional 1% peaks.

Hi Scroobius,

What I mean is that in your pics the USB2 core #8 has a nice driver pattern. In the USB3 situation this apparently changed to core #3 (I think) and doesn't look as tidy.

Later I will post some pics of my CPU usage (only 4 cores).

SFS loading peaks on my cpu are 100%, strangely this is no different than on my atom (with lower sfs of course)...

regards, Coen

Hi Coen - The pics are a bit misleading I snapped the USB3 pic as it blipped up a little. There are similar blips with USB2 when the processor goes up to 1% for a short time. Generally there is not really any significant difference I would say - maybe I should spend more time looking at it to be sure. On both USB2 and 3 occasionally every few minutes there is a fast short blip on all cores up to 100% which as you say could be SFS related.

For me anyway with USB3 and now with Peak Extend *on* never before have I heard such relaxed presentation of fine detail.

Coen, I think I told it before (in another topic), but the CPU *always* gets to 100% when track(part)s load. One thing : the faster the CPU (or the more power because of more cores) the shorther the peaks will last. En then another thing to take int account : at least on an i7 you will never see it last longer with TaskManager *and* W7, because TaskManager itself stalls (you can just see it stop). But just look, and see that the stall takes maybe one second, and that is how long the peaks actually last.
Lower the SFS and you'll see the stalling getting shorter ...

FYI :

A week back or so, I uninstalled the Phasure driver and reinstalled it USB3 connected. I never heard one "crack" since. So there something matters too.

But notice what I said earlier : after connecting to USB3 the first time, nothing auto-installed on that port, and possibly this is not right.

Regards,
Peter


PS: Still liking it.
In my case I don't see different CPU behaviour.

I did find the same thing on my recent USB3 installation .

Hello ,

I mean that with USB 2 ( and USB3 disabled by bios ) the max SFS my system could play , and after 2 or 3 reboots before going to Minimized OS , -was- 350 sfs SC .

Connected to USB 3 , it play at 400 sfs max . SC.

Actually in Minimized OS it goes to 500 SFS SC , seems a good result to me ...

Having saying that , trying back the USB2 , the sound is stronger , like there is some power added to the bass , it's a bit more "difficult" to listen to , but instead apparently more clear , and it goes to listen at a minor "gain" ( volume ) . Oh and the SFS set is still about 500 ....  innocent
Soon I'll disable the USB 2 from bios and report back some impressions with USB 3 again , which for now produces some clicks now and then to the reproduction .

Well , for me when in USB 3 , the reproduction is just more Gentle . More gentle in the "pianos" , and overall more relaxed . I like it .

No clicks at all after the disable of usb 2 and usb legacy .

Regarding SFS , it feels comfortable at around 400 , SC .

Here are my pics.

PE turned on, reinstalled the XX driver on the USB3 port and killed the usb3mon process.

Stefanobilliani made some sq comments that I second. The sound on USB2 is more compact and less controlled. Tonally there is quite a big difference in favour of USB3. Still something irritates me about it. Maybe it is because on USB2 I hear more of the instruments playing together. Maybe my cr*p recorded tracks sound more like they ought to. Still looking for it.

On the other side: I find it hard to believe that the cpu load of USB3 has a favourable effect on SQ, au contraire!

What you see in the first core is pure the driver (except for the large spikes); Are you sure all further settings are the same in both situations ?
Notice that this graph is influenced by the combination of Q1 + Device Buffer, Clock Resolution and Buffer Size in the Driver Control Panel (and Special Mode vs Adaptive, but you don't use Special, and of course WASAPI vs KS).

They are made with exactly the same settings.
The USB3 driver part of the graph is almost twice as high as the USB2. USB3 peaks at 8%, USB2 at 5% (as you can see). The flat part is 5% on USB3 and 3% on USB2.

I took the best looking USB3 shot to illustrate the difference in load. I have pics where the driverpart is hardly recognisable.

yesterday I updated the mobo Etron USB3 driver to the latest version (21-3-2012), but still I get the "set pauze on pin error". Strangely enabling the USB3 on the mobo did something positive to the sound of the PCIe USB3.
