Windows Server 2012 Standard/Datacenter Additional License Install (4 cpu) Activate

God knows what you're trying to do and why, but if you really must fry the processors...

 

160 VM's running in parrallel. Run something really CPU intesive in each one like Prime95. I'm sure there's cheaper/easier/more responsible ways to fry eggs, but if needs must...

while rendering 3D images and videos, the more cpu usage I can get will make rendering quicker.. that is why i'm trying to get 100% cpu usage. the softwares i'm using have no limit and does recommend very high end processing power. its windows server thats limiting my processing power.

Ahh, now makes sense what you're trying to achieve!

 

Forget Hyper-V, Windows 2008R2 supports 256 logical processors and Windows 2012 supports 640 logical processors (Windows Server - Sockets, Logical Processors, Symmetric Multi Threading - Matthijs's blog - Site Home - TechNet Blogs) with up to 2Tb or 4Tb of RAM respectfully on Standard/Enterprise/Datacenter x64 editions.

 

You don't need to enter multiple license keys - just the one. So that just leaves the software you are running. Trouble is I don't know the software or what it is trying to do - how it is designed to work. Could be that whatever you've been doing so far just hasn't stretched is enough to require spawning more threads? The software might support using your setup to the max, but if it doesn't need to...

 

I'd suggest asking the developers of the software.

using hyper-v allows me to use 100% cpu with the 64 logical when using the apps though..

Ok, let's take this right back to the beginning - have the software manufacturers stated that they support 2012?

 

2012 included a complete rewrite of the underlying kernel and related gubbins. Many things that work perfectly in 2008 R2 have issues on 2012.

 

Just like some software that works on Windows 7 doesn't work properly on Windows 8.

I suspect it's more a case of the task can't be broken down in to any smaller chunks. Everything has it's limits. An example might be encoding a video on 1 CPU taking 80% load or a 10% load on 8 CPU's. But still only 10% on 8 CPU's when 10 CPU's are available because the task can't be broken down into enough threads to use all 10 CPU's.

 

@dbmix has 80 CPU's and he want them to all run at 100%!?!? Assuming 3DMax supports all 80 CPU's there's no reason to think it's going to max them all out when rendering. Sure it might max out 8 CPU's but when the same job is split over 64 CPU's and doesn't even touch 18 CPU's let alone top 50% on the ones it is using, he is panicking.

 

@dbmix, do you have a lot of 3D tasks to render? (I assume it's your main business given the beast of a server). Maybe running 3-4 copies of the program in parallel and getting them to run separate tasks would be the best use of the available resources?
