DELL PRECISION 7920 Freezing (Windows 10)
Guys,
We have a few of these models with 144GB of RAM. One with 160GB. Windows 10. From time to time (one machine experience this almost every day). There is an odd freezing where the user can move the mouse do some clicks, but nothing works correctly.
By default these builds came with less memory, we upgraded them and also removed the default GPU (small quadro) and replaced that with a RTX 2080 (with the latest drivers)
Now, I installed w10 clean (2 days ago) with the latest drivers from DELL's support page from here: https://www.dell.com/support/home/us/en/04/product-support/product/precision-7920-workstation/drivers
Everything works until when the user comeback the next day or the same afternoon the machine is in this state where nothing can be done (is not completely lock per se).
I've changed the power management settings, the NVIDIA power settings to not avail. I believe that this is a hardware issue presenting itself and affects the OS, or viceversa an OS issue (with the latest updates) malfunctionong due to some bug in this specific hardware, etc.
Any help is appreciated.

@luke357 I suspect the issue is being caused by an incorrect memory configuration. Even though the system will support up to 1.5TB of RAM it has to be populated in certain configurations. 144GB and 160GB are not supported configurations. 128GB and 192 GB are your closest memory configurations
I would recommend following this memory config guide for accurately populating the system - https://dell.to/3aWgFOP

Right now was testing with 128GB before I saw your reply, I will post my results in the next few days, Thanks for the quick response, I've read that document, however. I have a question for you:
- Then using a non-supported ram configuration can lead to (weird) side effects? That's totally crazy but if the system is designed that way, it's what it is. The memory are the same type, speed, etc.
Also, I have 4x32GB {128GB} (besides the 4x8GB {32GB} from DELL), and I see that is not supported on any row of the memory table.
First: with 4x8GB I can use S32R on D2,D4,D3,D1 but with my currentr 128GB (4x32) I cannot since a 128GB config is only supported twice (S128R and D128R) which both use 16GB modules (mine are 32GB)
So my option is to go for 256GB (with S256R) if I want to use these sticks since I have only one socket therefore D256R is out of the question, I'm correct right?
So I suppose that to use them

That is correct, memory needs to be matched exactly for optimum performance. This is even more important in these workstation towers which can support vast amounts of memory. As you say, they are designed that way.
I have seen 3rd party RAM causing massive headaches on systems, they either throw up weird issues like you have encountered or simply don't even complete post.
I would also ensure that the BIOS and chipset are up to date.

Yes, that's correct. DxxR and DxxxR configurations can only be used with two socket set ups.
As suggested by yourself, the S192R should be fine.
Thanks ^AR

I've removed the RTX 2080 and all the RAM but the original ram that comes with the system. I replaced the gpu with a basic one and I'm running the Windows Memory diagnostics tools, let's see what happens.
