While we are sharing tips for best performance when using the S3 I thought I would share my recent discovery in the hopes that it will save someone else a lot of frustration. I use my S3 with a Lenovo W540 laptop (8 year old i7 workhorse with swappable batteries and swappable internal SSD caddy), most often in a very warm vehicle or on a mountaintop in the sun. Often I found that after recording at 24MHz for over an hour the live audio would stutter and recording would become impossible. I tried adjusting Windows Power settings and cooling the laptop without any improvement. This week I opened the laptop, cleaned out dust and applied new thermal paste to the CPU and graphics chips. To my surprise the laptop ran about 10’C cooler but again, after about 2 hours the skipping returned. It was obvious to see what was happening. Task Manager under normal conditions would show the i7-4800MQ CPU@2.7GHz running at 3.38GHz (overclocking???) but when the stuttering started Task Manager reported that the CPU had dropped to 700MHz! What I finally discovered was that the gaming industry has been dealing with this problem for years. Intel SpeedStep seems to be causing the problem. In the laptop BIOS (picture below) I disabled Speed Step and now Task Manager reports a steady 2.69GHz. I’ll give the laptop a field test next week but so far it has worked flawlessly at home.
S3 needs an exclusive USB3 port for continuous operation, no other power consumers connected. For problems with unattended automatic start remote I recommend this:
