Latency, pops, and sync loss

I am relatively new to Sonar, I had been using Logic Pro for some time. I am running it on a quad core processor with 6 gigs of ram and a 640 gig hd. I run my audio through a presonus firestudio and use the ASIO drivers. First I was getting pops and crackling when I was recording so I adjusted the latency and pretty much got them to go away but I had the latency bar set at the safest possible. I would then get audio that would drift out of sync half way through or sometimes from the start. So I moved the slider to the left, eventually all the way left and I was left with digital sounding vocals, sped up immensely, and crackling horribly. I am not sure if the pc just isnt fast enough. I am running Vista 64 bit and I took all the services off that I didnt need, set it for best performance, and chose minimal visuals(task bar etc.). The computer was disconnected from the internet, antivirus was stopped. Any idea of what is going on? Thanks.

Did you try THIS ?


Edit: and welcome to the forum :-)

Thanks for all the responses, guys. The firewire card I have is a VIA, I read that they should be ok with presonus equipment, is that correct? I ran the latency checker and it says that the machine should be able to handle realtime streaming of audio/video without drop-outs.

Ok I will do that. Its unfortunate because it ran perfectly in my macbook for so long but the mac is just too old and slow now to process plugins of any size, so I was forced to use my desktop which I thought would be even better. I guess not.

There you have your problem!----> People Running old XP tweaks on VISTA & Windows 7... That will  make your system NOT WORK instead...

You can start with turning ON--->activate AERO ON again--->FULL graphic-mode....
Re-activate virtual memory and let WINDOWS decide virtual memory. Go back and restore the whole system system. Set the processor scheduling to "Program" again ---->not "Background service"


Basicly the only thing you should turn off on VISTA / Windows 7 is UAC nothing else -------->if you don't know what you are doing. I don't know your skill in working with OS systems but with all respect.. unfortunately that don't seem to be case when you have turn off AERO on VISTA? 
Its very important that AERO is turn on on VISTA and Windows 7.


Just so you know 98% of all VISTA & WINDOWS 7 tweaks you can find on the INTERNET  is just wrong system tweaks my friend! If you interesting to learn more about how Windows 7 works learn from the real "pro"'s the guys programing and building it. You can start watching this 45min long Video with Mark Russinovich.

Did you ever check for IRQ conflicts?
Have you tried WDm driver mode?

Im betting its your laptops built in FW card. Most of them are crap. To rule out your FW card, try using your onboard sound chip to see if you stop getting those artifacts, as Presonus sound cards need a TI FW card in your pc

Try --->ASIO for all!

I just got a TI chipset and I am getting the exact same pops and clicks, so I will be returning that card. I was mistaken previously, I had said that I was using ASIO but I actually have been using the WDM mode because the ASIO wouldnt even let me record to a track, a box would pop up and it said that it was incompatible and to go to sonars website for tech problems. I disabled the network in device manager but not in my bios, however, I dont have a wireless card in the pc. Im pretty much stuck
