Topic: Windows 7 DPC latency problem
I have very high latency as you can see here :
Windos XP :
Windows 7 :
My system is:
Model : Intel(R) Core(TM)2 Extreme CPU X9650 @ 3.00GHz
Mainboard : Gigabyte Technology EP45T-EXTREME
Memory Module : Golden Empire CL7-7-7 1GB DIMM DDR3 PC3-10700U DDR3-1334 (7-7-7-24 4-33-10-5)
Adapter :ATI Radeon HD 4870 X2 (1GB, PCIe 2.00 x16, PS3.0, VS3.0)
WDC WD740ADFD-00NLR1 74GB (SATA150, NCQ, 16MB Cache) : 69GB (C:)
WDC WD5000ABPS-01ZZB0 500GB (SATA300, 3.5", 5400rpm, NCQ, 16MB Cache) : 466GB (D:)
WDC WD3200YS-01PGB0 320GB (SATA300, 3.5", 7200rpm, NCQ, 16MB Cache) : 298GB (E:)
PIONEER DVD-RW DVR-216D (SATA150, DVD+-RW, CD-RW, 64kB Cache) : N/A (G:)
FireWire/1394 Controller 1 : VIA VT6306 VIA Fire II IEEE-1394 OHCI Link Layer Controller
FireWire/1394 Controller 2 : Giga-Byte TSB43AB23 1394a-2000 OHCI PHY/link-layer Controller
I have installed fut_win_fire400 1.67, 1.69, 1.70
And w2fire_2993, 2998, 29991,29992
I did tests between the drivers and firmware but i still have the same problems on Windows 7 x86 & x64 and Vista x86 & x64.
I've tried the following already:
- updated Win7 til the latest patches
- setting windows for performance (no aero or anything)
- changing to the FW legacy driver (went back and forth with the different drivers a few times)
- different buffers (from 256 to 1024 samples)
- different rates (44, 48, 96)
- enabling/disable "Allow applications to take exclusive control..." on the playback settings of windows sound properties.
- installing/reinstalling latest and previous NVidia Geforce drivers for the 9800GT
- disabling write cache on the hard drives
- setting all power options to performance (never turn off anything)
- disabling Realtek HD audio (on board sound)
- Go to the run box and type regedit Go to the hive: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Audiosrv
In the DependOnService remove all entries except RpcSs and then restart your computer.
So is there enybody with the same problem solved?
Anyone from RME?
What is the secret of Windows Xp and it works so smooth without crackles and pauses?
