      Introducing T|I Marketplace/Classifieds!   11/24/16

      After a long wait, Tech|Inferno now has a Marketplace/Classifieds section where all registered (promoted and above) members can participate in selling, trading and seeking out items. This service is free to all members to use as they wish. Currently all ads last for a period of 14 days before they expire for promoted users. Those users belonging to T|I Elite, Contributor, Developer and Moderator have access to 30 day ad periods that are featured   Some easy rules to remember: Do not post multiple ads of the same product. Do not advertise here if you are a retailer or business. You must contact Tech|Inferno for advertising space. Keep ads civil, do not try to lowball members. You may contact them in private via PM if you feel their price is not to your liking. Harassing members will result in an infraction. It is recommended you have Heatware/eBay feedback to establish trading credibility.    Tech|Inferno assumes no liability for any sales posted in the Classified section. Always use common sense when buying/selling with traders and ask for their heatware/ebay feedback!   Enjoy!

  1. Nah, I rarely use Optimus (am on a 4K 60Hz at work and a 1080p 120Hz monitor at home for gaming) so I haven't tried to overclock the internal display at all.
  2. @Jmlee5 - in macOS I use it with the laptop open, and use https://github.com/Eun/DisableMonitor to blank the laptop LCD and prevent my cursor from going to it. I have a 4K IPS panel at work that I hook directly to the 980 via DisplayPort, and that is my primary monitor. I never tried clamshell, though I used to have the laptop open slightly (around 10-15 degrees) underneath my monitor stand...but after I had to take it into AppleCare for a display failure, and noticing how hot the surface of the display was getting...those two facts may not be related but it scared me enough to always try to keep the laptop open at least 90º when using it with the eGPU. I have no acceleration issues on FCPX or 3D apps (Elite Dangerous on macOS uses the 980), but it's probably because I'm using an external monitor.
  3. https://www.techinferno.com/index.php?/forums/topic/10107-15-mbp-gt750m-gtx98016gbps-tb2-thunder2-ammo-case-w10macos-1012-sierra/ ^ my build thread with that exact laptop (save for a 2.8 GHz i7 instead of a 2.5). Didn't really have any more issues than usual.
  4. @irokez dude lol you're posting a general tech support question directly into my build thread FYI haha. Might wanna post it somewhere where it'll get more hits, like a new topic in the eGPU experiences forum. FWIW I think it's your PSU as well.
  5. Added this to original topic: (NEW) FIX FOR macOS NOT POSTing: Run Goalque's script in "-a mode". This apparently alters something regarding the thunderbolt chipset on every shutdown, so when rebooting back into macOS, the eGPU will initialize properly every time.
  6. A little late, but I'd like to reply that when running macOS (shutting down from macOS, starting back up in macOS), running the goalque script in "-a mode" actually solved this issue 100% for me. That being said, Windows booting is still the same crapshoot, and running the script in -a mode seems to prevent Windows from detecting the eGPU on first startup (gotta reboot into Windows twice for it to work).
  7. I'm running the green LED light bar seen in the main pic off the fan header on the Akitio PCB. Didn't work when I tried it on the LED header (probably not enough power to run the whole row of lights)
  8. Hi@goalque, the thread you linked is mine; are you saying that if I were to run automate-eGPU.sh -a, that my random-non-POST issue should be resolved?
  9. Literally in this same forum, one post below this thread is an Optimus "internal LCD mode" guide.
  10. It's not goalque-script-easy, but I regularly LAN party without an external monitor, using my eGPU for Optimus, on my dGPU-equipped MBP. Details and process are in my build thread: Also, OP: nice setup! I'm jealous of your Ti.
  11. Damn. I'm stumped. I know that the 970 for sure works with Optimus as one of the guides I used for enabling Optimus was running a 970. Wish I could help figure out your problem but I'm at wit's end over here. Sorry man.
  12. ...weird, it shouldn't say inactive. Does the 970 show up in Device Manager okay? No exclamation marks or "device could not start" messages? You're booting up with apple_set_os before you boot into Windows, correct?
  13. Just to check the obvious, the 750m is disabled while you're trying to run Optimus, correct?
  14. Here's what it looks like on my end. Maybe try creating a program-specific NVIDIA settings page for furmark and setting it to use High-Performance, see if that changes anything?
  15. That is the oddest thing. It does look like the apps are running on the wrong card, but what's weird to me is Furmark's benchmark report... It says the renderer is the Intel GPU, but has the PCI ID of the GTX 970 (10DE is NVIDIA's Vendor Code...) I'm really stumped at this point. Does the 970 work when you have a monitor hooked up to it, and boot into Windows "normally" (i.e. non-Optimus mode)?
