So I have made progress on the C3 Serum issue. I used various interfaces with the same result, drop outs immediately. I was using a Toshiba Satellite LT with a 4th gen i7 quad core cpu, SSD and 16gb ram. I decided to bring out my older, very heavy 17 inch HP Envy DV7t with a 3rd gen i7 that is hyperthreaded. I had installed an SSD in it, to make it faster. I used it for my masters degree program and Studio One for quick loop development ideas etc. It was fully configured as a back up in case the Toshiba failed at a gig (we rely heavily on Ableton). I never really used it. So, I installed C3 on it and Serum. No CPU overload, not even close! The difference? My theory is that Toshiba MB chipset and manufacturer is crap. I know Dell uses Foxconn which I despise. HP, however, uses ASUS for the MB, which is why historically, I only bought upper end HP laptops. When I see complaints about HP, it is usually the garage sale type people, or the $399 laptop cheapskates. Of course those LT’s won’t do well, the buyer should know that (including me!). I plan to investigate the MB maker of Toshibas. I hate Lenovos. I have repaired laptops since the late '90’s and majored in computer science at UC Irvine before falling in love and moving to UC Santa Barbara which ruined it all. (enough about me). That said, I am migrating all of my stuff back to my HP, and begin looking for a trustworthy, high end HP LT. Only reason I went to the toshiba was because I went in to purchase DVD’s at Officemax and the display LT that went for 800 bucks at the time was sold to me for 400. It was one dollar more than $399, so, technically I am not a cheapskate! (the guy at officemax said, “What price would make you want to take this home today?” I said. “400,” and he said, “done with full warranty. We have new LT’s coming in for the new school year.” Toshiba runs cooler, and is lighter. So I moved everything to it. It’s newer, right?
Moral of the story, just because it is a quad core i7 later gen. does not necessarily mean that it is better. MB, chipset, maybe hyperthread. Better to use an older beast than a newer house pet.
