DPC Latency spikes
Hi
I have been having problems on my PC with pops and clicks in audio on the following setup
Mobo: Gigabyte EP45-UD3P
Proc: Intel E8400
Ram: 16GB OCZ Gold Ram
GPU: NVidia 9600GT
HD: Corsair Force 3 120GB
Sound: Focusrite Saffire Pro 40
I have stripped back the motherboard to bare minimum, change W7 settings to performance and the DPC latency results for the E8400 are shown as the left pic. For testing I replaced the CPU with a celeron and the celeron results are also shown as the right pic.
I have also tried different RAM with the same results, disabling processor control in BIOS and disabling LAN, Firewire and USB. In addition I have tried the mobo without the GPU and testing via RDP.
Can anyone shed any light on what this might be? Do I have a faulty mobo?
Thanks
