Hello,

Im trying to optimize power usage.

12700 non-K, in default 65W mode.

Right now HT disabled, so i have 8+4 cores and 12 threads.

I want to know how many P-Cores can be disabled without affecting unraid performance, mainly parity [x10 14tb HDDs + two 16tb parity HDDs, plus some SSDs for cache]

Im not using any VM [service disabled], so far the only docker i used is Krusader.

System is just for NAS + DLNA streaming + something [no idea yet what it is] to backup everything to GDrive,

no encoding, no working on it, no virtual machines [unless there is a way to take an NVMe that has windows 11 installed and move it to unraid VM, otherwise if i ever need a backup PC i can dual boot into windows 11, but ill lose the hard drive access than]

 

 

Anyone?

I'll give you my two pennies after building with a 13900K. Ultimately when the cores are at idle, they are sipping power so I feel like disabling them to squeeze out maybe 0.25watts is a bit of a stretch, even disabling HT seems like a bit of an extreme measure.

 

You'd be better off limiting the turbo boost which looks puts a power draw ceiling at 180watts. unRAID will run time at the stock 1.6/2.1 of your E and P cores.

 

unRAID will have no issues running at those frequencies with the 8 P cores and 4 E cores.

 

For reference other unRAID box which ran Dockers for Plex, *arr services, Transmission, nGinx, MariaDB, and PiHole did so on an Intel i5-9400F (https://www.intel.com/content/www/us/en/products/sku/190883/intel-core-i59400f-processor-9m-cache-up-to-4-10-ghz/specifications.html) which had six cores and no hyper thread. Base clock of 2.9ghz, turbo boost to 4.1ghz; ultimately this box never broke a sweat, even if running an additional Windows 11 VM.

 

TL;DR - just let it run, I had a server with far less and you're not going to gain enough in such minor tinkering only to realize you may want it back; just limit turbo boosts and you'll be fine.

So parity calculation doesn't need a lot of CPU power?

If i run a VM and set all the P cores to Windows VM, leave the E just for unraid will that be OK too?

 

What about RAM? Im thinking if i should use 64GB kit or sell it [I have used 5950x + 64Gb kit and mobo]

Right now my unraid has 32gb.

 

I want to use dircache without the option to free the used RAM, and i want to have windows 11 VM [already installed on nvme, so i heard i need to pass the NVMe to empty VM]

and i want to eventually create a hackintosh VM [just for lols to see what it is about, to learn, maybe a linux VM also to learn and android VM if possible, ill never run more than one at a time], i installed extra 512GB SATA SSD to use for virtual disks for VM and windows 11 has its own NVMe so in theory should be enough.

 

Also i want to remove the last HDD from my main build, for that i installed two 12Tb Segate NAS pro hard drive on unraid that i had in a bin, i plan to set them as BRTFS raid 0 and use as remote share for old games and emulators, my main PC has just about 20TB of SSD space so i cant afford to waste it on emulators and random crap

 

 

And everything i want to do i want to somehow make the system power efficient, because im the only one that use it, so when i use ONE function all the rest go to "sleep".

 

 

I see you know about VMs, i have no idea about that, do i need to lock CPU cores for VM or there is a way to have all cores available for everything, like unraid, dockers, and one VM [ill never use more than one VM at time]

 

Or i have to lock/allocate cores for each separately?

 

Thanks

Probably even Pentium/modern Atom will be enough. 12700 is an overkill already.
I use 5900X, but I host game servers etc. For pure NAS, nothing fancy is needed.
