will i ever use more than 64gb of ram ?

[OCD-FREAK]

hello everyone,

 

will i ever be using more than 64gb of ECC ram in a dual socket motherboard running xeons ? my work involve hardcore workstation tasks : like 20 virtual machines, massive rendering, 3D modelling, intensive nuclear simulations and alot of crazy stuff like Matlab Simulations and SIMScript.

 

any and all opinions are more than welcome.

 

thank you all

If you're doing 20 VMs then you're going to average 3.2GB of RAM per VM (if you distribute evenly of course). From what you've described doing I would say you could definitely use 64GB of RAM pretty fast.

Quite possibly with a lot of VM's like your suggesting.

For 20 virtual machines doing these things, you'll probably need a minimum of 64GB of ram.

Wow! Really! By the way i was Thinking of buying 128gb of ram instead of 64gb but thought it would be too much expensive and just outside this planet, lol

What motherboard and Xeons?

If it uses DDR3 ECC memory then it shouldn't be that expensive, you can pick up 128GB of RAM on eBay for pretty cheap.

If it's DDR4 RAM though then that's going to be very expensive for 128GB worth of ECC memory.

Motherboard is the HP proliant G7, ddr3 memory and two xeon x5690. How much would 128gb of ram cost of ebay? Can you send me some links pls?

Depends on the speed you need but it looks like ~$500 is average for 8x16GB sticks

jesus christ ! that so much, if you where me would you invest that much for a socket 1366 dual socket motherboards with x5690 and 8gb x 2 graphics cards ?

What GPUs and what model of the Proliant?

proliant G7, two GPUs : ASUS RX580 - 8gb = 16gb GPU VRAM

Like the DL360 or DL380? Because if that's so I'm not sure how you're going to fit both GPUs in there with only one 2-slot PCIe space =/

i will be using PCIe extensions, i am not using a regular Computer case but a custom made one similar to those exposed cases used for mining rigs. model is DL380 G7

Ah, gotcha, so the server parts are just going into the new case then. Well then nevermind about the model worry

 

But yah, if your workload can make use of the extra RAM, I would make the investment. Just for comparison the same amount of DDR4 ECC RAM is about 3.5x as much

that sounds like you need a fully kitted serverroom, not a singular workstation.

 

at work we tend to average about 3-4 VMs per physical machine, although the latest HP DL360 G10 is posing new options to that limit

Dealing with a customer now who's got up to 25 to 30 VMs per server in some of their more densely populated areas of the data center.

In some cases it makes sense with low power/resource intensive stuff but they talk about it like they're going to start packing all of their servers like that =/

at least they're not relying on a G5 for their data storage

It's not intended to be a server. It's a productivity workstation, iam using two powerful gaming graphics cards in it (2 x Asus RX580 - 8gb)

it can be anything you want it to be, but 20VMs is the point where most sane beings outsource that stuff to extra machines somewhere on the network.
