RAM for dual gaming VM

Ben28282

I am planning on doing a dual user gaming thing (like what ltt did but not using unraid). I currently have 16GB of RAM and a 2700x. It will be used for esports (Fortnite/ Overwatch/ Rocket League ). One machine will have a GTX 980 and will be driving a 1080p 144hz monitor, the other a GTX 950 or similar driving a 1080p 60hz monitor. I would probably split ram 8/6 with 2 left for the hypervisor. Will this be enough or should I go up to 32 GB.

FYI I will only use this setup sometimes, so I can do a mini lan. Most of the time I will be bare metal booting.

Thanks in advance

Curious about what hypervisor you had in mind for this?


16GB might be tight at times.

Not just capacity wise, performance wise... The memory access performance uplift from rank interleave might be useful for this sort of build.

Probably kvm Edit: Will it change performance as I will still be in dual channel

Little bit...

8GB DIMM's are single rank.

16GB DIMM's are dual rank.

Rank interleave really cuts down on average access latency to memory. For a system being used to host 2 "gaming" VM's this might actually be a pretty useful performance uplift.

Might help cut down on stuttering and such. In some comparisons I've seen 10% performance uplift in some games.
