Hi Leon: Neal spent some time with me going over a list of services that can be stopped and disabled. Also we turned off most of the Aero "eye candy" (fade in/our, shadows, etc.) but the real culprit, in my case, was the anti-virus software. I was seeing the latency steady in the 140usec to 400usec range until I opened IE or Chrome and surfed the web. Then it would jump to 3000usec - 8000usec.
I don't have my F5KA set up yet - was just putting the PC together. My original plan was to run XP/pro but the PC was too new and I couldn't get XP to install - blue-screen-of-death (BSOD) and no drivers. 73 and good luck Sheldon -----Original Message----- From: Leon [mailto:l...@brunerweb.net] Sent: Monday, November 23, 2009 11:21 PM To: Sheldon Hartling Cc: flexradio@flex-radio.biz Subject: Re: [Flexradio] Power SDR Freezes continued Sheldon- Thanks for the suggestion. I removed the security software (Microsoft Security Essentials) and it had no effect. What I might try tomorrow is installing WinXP onto the system from an extra HD I have and see if I can get the hardware to work with the older OS. At this point I'm not sure what else to try... 73, Leon Sheldon Hartling wrote: > Hi Leon > > I just went through the same thing with a HP Pavilion Elite m9450f running > Win7 (Asus IPIBL-LB motherboard aka HP Benicia-GL8E).
