are there a lot of motherboards that can take 64gb of ram?
I want to make a ram drive to boot an OS in. I want to play flight sims in it. Would the best thing to do be install a small version of linux on the base drive, then create a RAM drive then put Windows in that space, then boot from it in the VM?
what OS can host a VM with the least computational overhead?

why do you need windblows to be on a ram drive
>pcpartpicker.com
there are some listed with 16 slots for ram that say they can hold 1tb wtf
>can hold 1tb wtf
our test machines can easily run 100x tests that take 4 gig each
Any Ryzen board can take 64GB, as long as it has physically enough slots.
Either two 32GB sticks or four 16GB ones. Those would be the most widely available consumer options.
If you want to use Windows, that's probably the best way.
Otherwise you can deploy a Linux image each boot into RAM and back it up each time you shut down. You might be able to pull it off with Windows too though.
In the end I still recommend a RAID array with NVMe Optane drives. Two drives 32GB each in RAID0 won't set you back even €100 while giving good enough performance and 64GB storage to rival RAM in real world use. You're not going to utilize all the bandwidth and IOPS you gain from a RAM drive in the best case scenario.

100x what

interesting , why do you say that
nice trips
It's a cheap alternative solution for OPs usage. This would cost less than 16GB stick of DDR4.
A dual NVMe to PCIe x8 or x16 adapter and two 32GB NVMe Optane drives in RAID0. I recommend RAID0 because Optains sequential read/write speeds are not that great, but two drivers together deliver much better sequential read/write speeds and massive IOPS. Fast enough to rival RAMDisk for real world usage like running a flightsim off without being indistinguishable for such a usage compared to RAMDisk.
I thought real hardware raid cards were expensive, do you have one you recommend
Which flight sims?
Flight Simulator X (which is huge with huge maps)
and Kerbal Space with a shit ton of concurrent missions running, get's more stutters than you would think
I also just want a bad ass instant access drive because reasons and benchmarks for my own personal jerking off
You don't need hardware RAID for that. Both firmware (if supported) and OS RAID (always supported) will work fine for what you want to use it for, so a passive NVMe PCIe adapter is all you need. Multicore CPUs will only use a fraction of one core to manage the RAID, there isn't any noticeable performance degradation for such use.
Oh I was always told software RAID 0 was not nearly as good as hardware raid for performance
There isn't any substantial difference for your use case. Both would work fine.
I'm running X-Plane 11 with scenery addon (around 57GB) and maximum details on 4 SATA SSDs in software RAID0, it takes me around 28-38 seconds (depending on map) from clicking on the icon to being in the cockpit ready to fly. Once in the game there is no shutter or pop in.

see with a RAM drive this should be 2 seconds
that's what I want

can you boot from software raid 0?
why would people use hardware RAID?
No, even in my use case with 2700X, most of that time is spent on processing, not actual disk access. Making the disk any faster would not make the game load faster anymore.
That's why it was mentioned that in the real world, the difference between a RAM disk and a few Optane drives in RAID would not be noticable, as there is only so fast you can go before other things become the bottleneck.
Depends on your BIOS. Most boards can boot at least off SATA RAID, new ones can boot off NVMe RAID too. Hardware RAID is better in most cases, but more expensive (a lot more to actually be better than software RAID) but for things like loading games off, the difference won't really be noticable, think editing 8k RAW video files or serving hundreds of torrents at once (if we talk about consumer use), those are workloads hardware RAID would be suited better for.
its dumb we have 64 bit cpu's but no apps available for 128gb of memory.
I think there are rack server components that function as multi terabyte RAM disks
i wonder if one of those could be adapted
But we do. Everything from home usage like compiling, content creation, neural network training can eat up as much memory as you throw at it and that's not even why we have such memory options, when we take servers, they need to hold a lot of data in memory all the time.
thats nice for creatives but not important to consumers
I'm talking about consumer use here. That's why there is workstation gear to sell for consumers in the first place.
I've run 2 different motherboards from 2 different manufacturers with double the listed maximum supported memory without issues.
Most memory limitations are artificial and exist because they are reasonable
Like many boards having a limit that's just the biggest single stick on the market times the available slots on the board at the time of release
I really want 32gb DIMMs already.
But we already do.
Where? All I can find for DDR4 is ECC DIMMs, nothing really meant for a consumer desktop unless they finally were made available.
VR Porn.
List of 3D XPoint models:
Optane Memory 16GB *NOT BOOTABLE*
Optane Memory 32GB *NOT BOOTABLE*
Optane Memory M10 64GB *NOT BOOTABLE*
Optane 800P 58GB *BOOTABLE*
Optane 800P 118GB *BOOTABLE*
Optane 900P 280GB *BOOTABLE*
Optane 905P 380GB *BOOTABLE*
Optane 900P 480GB *BOOTABLE*
Optane 905P 1050GB *BOOTABLE*
continuing this, RAIDing 3DXPoint literally does nothing to its 4K speeds and actually somewhat lowers it so its a waste of money unless you intend to increase storage
and continuing this flight sims are huge as fuck so you'd probably need to get more than 64gb which is like 199€/$ for 118gb 800p which sucks
still costs about as much as like 24-32gb of ddr4
