Before I try customer support… here goes.
Built a new PC and kept my 3 WD caviar black audio drives. Everything else is new. C: drive has fresh install of Win 7 64 bit. w/ all updates and fresh 64 bit and 32 bit cubase 5.5.3 full version.
Problem: ASIO time clipping. In playback and/or recording of one track with no effects, ASIO time usage goes from 1% to clip every few seconds w/ audible tick in both 64 and 32 bit cubase.

As cubase states on their web site it is meant to work with “normal” computers as long as the minimum requirements are met so I only did a few adjustments seeing that this is no slouch of a system. There is no blutooth and all updates have been done aside from bios update. These are some of the tips I found.
- Sys restore off
- firewall off
- internet disable
- power set max performance
- Cubase CPU energy saving off and multi processing on
- hybernate and screen saver off
- loaded legacy firewire driver
- disabled hyperthreading
- virtual mem. 0
- No secure sys running
Other thoughts: I tried to DMA: ON but SATA mode only works in AHCI and does not alow this option. There may have been a few other small tweeks I am forgetting. My system works great except for this one small problem. I set buffer as I would normally (256) do in my old 2 core AMD XP machine and even when I raise it it still clips. Also when I set ASIO to generic it goes away but at a latency of 40.0 ms not low enough for my use. I use to get 7-10ms with my old machine… What could it be?
