Did we know that we can control the L2 Cache Size in Windows

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

SecondLevelDataCache = 0 on standard

256KB: 100 hex
512KB: 200 hex
1024KB: 400 hex
2048KB: 800 hex
etc

You can speed up the PC giving it a value, well I think, didnt try it yet.

Roy

PS: probably it will be set automaticly already by the HAL.

To Mani,

Didn't you told here a while ago that you not using all CPU cores ?

Could this be a part of the problem ?


Roy

PS: Nice DPC value (should be around 10-15 range when xx plays)

PPS: Maybe do a BIOS update.
PPPS: Did you properly flashed the SSD's

What mobo do you have, because it probably does have a FW port,
only its on the mobo itself and you need to add a FW bracket.

Better use eSata btw, there are brackets for that too.

But get an internal hdd, would be better. (at least one)
You can also open-up the external drive you have and take the hdd out and put it directly in your PC.

Just some options

Brian,

What does the DPC latency checker shows ?

This could be related to the power scheme of W7 (Start--->control panel--->>power options)
Dont know for sure but try the: High Performance scheme.

Roy

First Gerard and Leon, nice post you guys.

Peter,

Little bit strange casing, but the more you think about it, its a good design.
Shielding the various sections, proper room for interlinks (kinda like that).

Made in Holland

Thank you Boleary (and Mani) for pointing that out a while ago, about the SFS.

I got very good results at high CPU speed (3,2 a 3,4Ghz) and lowest SFS (12MB).
This is at special-mode 48samples 1,30,30,0,0.
This is mostly for my ambient section.

I still have to try adaptive mode on other genres.
Also very difficult to find common sense in this.

Roy

Pedal,

Maybe a little offtopic here, but anyway
Don't underestimate the need for a "clean" speaker XO, trimpots to adjust the volume of seperate speaker-drivers in XO isnt the way, use for eg. high-end resistors. (L-Pad)
Maybe do some tweaking there, dont know about your soldering skills.

Just out of interest, maybe you can post/PM your x-over schematics or speaker type.
X-over looks kind of "dirty" to me, very simple to clean this up.

Trimpots in the low-end is not the biggest problem, but behind a tweeter is undone,
When I build speakers I always set the tweeter-volume by ear,
so get a handfull of resistors and 2 wires out of your speaker and just make several combinations to lower the output of your tweeter.
When this is found, then solder the resistor directly to your tweeter.

NO knobs/trimpots in the signal path, anywhere!

Roy

Hey Alan,

You can also use http://www.filemail.com/default.aspx

I think changing the default SFS from 100mb to 60mb would be a good thing,
especially for gapless playback.

What if high cpu speed IS important together with a low SFS.
XX is designed to run on 1 core, thats good if you have a dual core, one for #3Engine, one for windows.
but if you have a quad core can xx run on 2 cores instead of one.

Peter, is it possible to let xx run on 2 cores ?!

I think again, its all about speed,

Did anyone proved that underclocking is better vs more RFI ?!
The faster a pc can handle things, the more time there is to handle the music.

Speed, speed, speed.

Roy

Ofcourse a new knob is not desired not even 1 knob is disered, BUT, whe can learn from those settings and when we do,
I know for sure Peter will find a way to make "schemes" or "settings" depending on the genre or album.
We can not expect from him to test all options, there literary thousends!

I really DONT like knobs at all, not even check-boxes.
Peter needs to update the functionalty of the GUI together with the implementation of .ini files per album
when this is done you can put those commands under a remote button for eg, (or post them )
Also you can stay in your listening position and switch between settings or schemes you want to test.

I also dont like to "switch" everytime between adaptive and special mode when going from jazz to ambient for eg.

Roy

PS: hope this makes 4 cents
PPS: Dont forget Girder can learn all those functions and checkboxes when the xx form is fully "functional", it can do a string of command too.

Thanks for this nice post Peter, much appreciated !!

Perception of music is also a brainfunction, the most primal one.
Never forget that.

Its an .ipa file, thats an Iphone app.

I dont use apple or iphone so................

OK , found it
 

Will install and try!

Just terminate Dragon during playback of xx, nothing comes between me and SQ.
you dont need it, use IR remote to do for eg. an occasionally skip track.
You can open Dragon with your IR remote too, so..................

But think more like selecting next album by voice, this is were it can do its job best.

When I play music its mostly pretty loud, so.........have to try it with a proper headset.
