Hi there,
I have a very detailed problem and I have already tried a lot of approaches but with no result. I am with my nerves down so I would extremely apreciate any help. I'll try to be as brief as possible.
System Specs:
ASUS P5QL-E Motherboard (Latest BIOS)
Intel Dual Core E8400 3.0Ghz 1333 FSB
2 * 2GB Corsair XMS2 CAS 5 (Dual Channel Kit)
ASUS EN7300GT SILENT 512M
WD 250GB 7200rpm 16MB Cache
Hercules Dj Console 24bit/48000 Soundcard
ABLETON 7.03
Windows XP Pro 32 bits/64 bits, Vista x64
Problem behaviour:
According to my test the problem apears only under ASIO mode. If during playback of a track (in ableton), I move, resize or even select sequences or clips, I experience pops, clicks and drop-outs and somtimes even sudden bit rate drops (its like sticking a Bit Rate reduction plugin and drop the level to 1 bitrate). It happens when I switch from the Session View to the Arrangement View also and even when I resize views in Ableton. The things thin out if I increase the buffer size but still occur even around 1000 samples which is unacceptable.
What I noticed:
Firstly, I noticed that almost every time I move sequences, parameters, etc. the CPU meter jumps up about 15%. None of these happen when in MME mode (set at about 35ms latency using the test tone).
What I have done:
I am having this issue since I have build my new system which had a Gigabyte EP35C-DS3R before. After searching around I found that the most P35 Gigabyte boards had a problem with the DPC Latencies and I've done everything from flashing bios to emailing support to fix the problems. Enthusiastic I changed my motherboard to the ASUS on the above specs. I installed a fresh, clean XP x64 and found that the problem was still the same. Exactly the same. Furthermore, I installed XP 32 and it seemed to work better. The "things" occured more sparsely, but still annoying. I then tried Vista x64 and the promblems were at their peak.
Ambitious, later on I talked with a friend who came over with his Graphic Card (8 Series,nVidia, 1 GB Memory) and a stick of 1 GB ADATA RAM. I tried them one by one hoping I'l find what was causing the problem but I was brought down seeing the problem exactly like at the beginning.
Everything it's ruled out except for the CPU which I somehow believe is not the problem, but I am really baffled anyway.
Is there any1 who has an idea of what might cause my problems? I think it's a compatibility issue as I installed my Hercues Console and Ableton on my brother's computer (which is an old P4 with 512 DDR400 RAM) and the was no sign of the problem.
Thank you for reading my story

and I would really appreciate any help or directions from anybody.
