Loosing ASIO stability in SX3 after a while (XTC Mode)

Rinse · Post by **Rinse** » Fri Aug 11, 2006 3:49 pm

Hi everybody,

After beeing more of a reader on this forum for 9 years now, I have to make my first post now.

I am working with a P1 and P2 card and prefer to use XTC mode in Cubase SX3. after some tweaking and many helpful topics in this forum i got it working flawless.

But now.. i don't know what significant changes i made to my system but afetr a while using a large project in SX3 i have trouble with click and dropouts.. and the more i work in the project, more worse it gets until i cannot work with it anymore.

The only solution is reboot Cubase, then it works fine but comes back after a while..

I found it has many relation with my mouse movements and movement of windows/scrolling.

I tried fiddling with my virtual memory(which is turned off now 'cause of best performance). Hardware acceleration and the expert section of the Cubase settings but none helped..

has anyone any suggestions please?

i use

ASUS P4c800 Deluxe
P4 3.2 Gig HT
2 Gig RAM
Radeon Saphire AGP (Dualhead)
Pulsar 1
Windows XP (ACPI Turned OFF)

Any help would be appeciated,

Cheers,

Rinse

I just tried it with HT off, but there is no significant difference.

Some fiddling with my PCI Latency helped a bit, I tried low (64) normal (around 128)
and higher. best results are around 128

But no perfect solution.. Still dropout and cracks. Altough this PCILatency settings keeps the ASIO Driver longer from loosing stabillity..

Also still heavy dropouts when I scroll trough my arrangement and mixertracks.. this hints to a videodriver prob.. i think.

Thanks anyway

Have you tested the buffer size and is it set to 5292

ATI cards are known to have such issues, but make sure you have no irq sharing as well.

Also, just in case you're not, make sure you're using the Scope ASIO driver (you probably are but just making sure).

Also check & see if the problems when moving windows occur on the primary display window or only the secondary display (which usually suffers from higher cpu usage).

When's the last time you did a disk defrag? How old is the drive? Is this a new system or one that has been working fine for a long time (years).
