Ahh ok bummer, lets hope someone works it out one day! Re the temps in the picture I posted, that was from the system at pretty much idle, just wanted to show what the new sensor displayed.@bjay77 It's never been clear why sleep with an external GPU does not work but it seems to relate to how the internal screen on real macs of this generation wake and sleep, and the differences between different versions of DisplayPort but there also factors that relate to UEFI and the drivers for the HD4600 on OSX. The number of niggling things might be fixed in one clever hack but Im not confident that OC will help.
@StevenT introduced one of these in to one of the 7020 threads and it looks like he's found a fix, sort of.
Just noticed your temperature readings, why so low!
Just realised you may be talking about sleep without a gpu? If you are running Mojave-Catalina and Clover and only internal GPU, then sleep will work - with only the IntelME settings being a pain to fix. (see 3. Password Protect MBEx) but even then fixable
I was using my optiplex without a gpu for a while while I waited for the 24 pin adapter to arrive. Currently have a sapphire pulse rx580 installed in the MT, so I turned of legacy roms and disabled sleep...I just leave machine on all the time at the moment, that why i'm exploring new silent case and slow fan options to try and bring the machine noise at idle down to inaudible levels if possible.
