Hello i am trying to do GPU passtrough to a windows VM with a seccond GPU RX 570. my main GPU is a gtx 1080TI my idea is to have a windows VM with some games that just dont work on linux like destiny 2 and some others, at least thats the plan. and just use steamlink to stream the games back to the host os how ever wen i start making the VM in virt manager i get to the point of begin instalation and then i get a bunch of errors I followd this tutorial for the GPU passtrough: https://www.youtube.com/watch?v=QlGx0XvWuag&list=PLcO61Z91i1Oj2sqbedSYxLCcB4rqbCfGg Unable to complete install: 'internal error: qemu unexpectedly closed the monitor: 2020-05-20T07:58:13.836483Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(48BH).vmx-apicv-register [bit 8] 2020-05-20T07:58:13.836490Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(48BH).vmx-apicv-vid [bit 9] 2020-05-20T07:58:13.836494Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(48DH).vmx-posted-intr [bit 7] 2020-05-20T07:58:13.836497Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(48FH).vmx-exit-load-perf-global-ctrl [bit 12] 2020-05-20T07:58:13.836500Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(490H).vmx-entry-load-perf-global-ctrl [bit 13] 2020-05-20T07:58:13.868478Z qemu-system-x86_64: -device vfio-pci,host=0000:02:00.0,id=hostdev0,bus=pci.4,addr=0x0: vfio 0000:02:00.0: group 1 is not viable Please ensure all devices within the iommu_group are bound to their vfio bus driver.'

i have never build a Cascade unit before looking it up i find limid info and see that it is the same as phase change? corect me if i am wrong. Also it would be nice to fit in to the case (thinking of going with the thermaltake 900). A small unit next or below it would not be a problem but if i have to make a huge box of some sort it will be a bit mutch

a multi stage phase change might be able to go below -100 but i have not found them commercialy only single stage. and it is not just for overclockign also just for fun and overclocking

i found this https://www.digitalstorm.com/cryo-tec.asp

well there do exist semi closed systems only thing needed would be a compressor for the ln2 but that would get to bulky

a freezer works exactly like phase change not a chiller as far i know? a chiller is not using a compressor and gasses a phase change/freezer does. also the reason you cant put a freezer on its side.

A chiller can not go below 0 it is using water. multiple KW well i am already consuming at least 60KW 24/7 so... but if there are any good options to get to those temps with out geting to bulky like a ln2 compressor or a whole room with a cool instalation. the only other thing i know can get super cold is amonia cooling but i have no idea how it works

as far i know you can stack peltier to get them colder so to get -100 you use 3-4 peltier and the phase change on top. well that was the idea

Looking at this it seems they can https://www.quora.com/How-cold-can-a-Peltier-device-get for overclocking if there is a other cpu with a ton of cores and that socket that can overclock realy well at those temps then i will choose that cpu

are there any other options to get to cryogentic temps without having to keep refiling some thing like ln2 just give it a ton of power and it shut work. about power consumption i dont care if needed i can jst use a few kw if i want to

The reason I am looking at peltier is they can reach cryogenic temps for my understanding and phase change can get around -30 at best and I am looking for some thing to cool 24/7 to around -100 and below. I have seen L&L cooling for ln2 how ever this is not a good choice for 24/7 (l&l cooling makes semi closed loop systems for ln2)

Hello I am going to build a new PC. For the CPU I am going for a AMD Threadripper 1950X. For the cooling I am thinking of using a peltier stack and to cool the hot side of the peltier with a phase change (LittleDevil LD Phase Change) I don't really care about power usage at all. The things I would like to know is. Is this even possible? Will a phase change be able to cool a peltier stack (ranging to get around -100/-150) how bad is it for the CPU when having the PC on for 24/7 even with really good isolation.

Yes it is gigabit

it is killernetwork and i did set it to gigabyte

I have recently reinstalled my own PC with windows 10 just to find out my internet speed has gone from 500mb download and 70 upload to just 100download and 20upload. This is a windows problem not a PC problem on my PC I also run manjaro and there the internet speeds are fine. Now I have also reinstalled the PC of my sister because of some memory leak problems (memory was always at 80-90% in use even when 0 programs are open and task manager says the highest usage is about 2mb from the 16gb) and again the internet speeds are gone from 500/70 to 100/20.
