64GB + Optane Limit

[watham]

Hi,

 

I have an HP Prodesk 600 G4 SFF with an i7 8700 that supports up to 64 GB of RAM & Intel Optane in it's 4 slots.

 

My question is simple. HP's specs say only 16 per slot of normal memory, but optionally 2x32 + Optane would be great.

 

Does anyone know if this will work?

There is a good chance that 32 GB dimms are not supported, for 64GB I would say go for 4x16 in this system

 

As for Optane, this system does support Optane m.2 storage drives, but because you are talking about memory I have a suspicion that you are thinking about Optane dimms, they are not supported on this platform

Optane in this system and other consumer systems is a NVMe drive, and can't be used as RAM. It will shot up like any other NVMe disk to the system, except for support in the Intel caching software. 

 

It might be possible to get 128GB with 32GB dimms as systems frequently support more than the rated ram as bigger dimms are released and spec sheets not updated.

Officially thr 8700 has a cap of 128gb. As the memory controller is on the cpu there is technically no reason that 32gb sticks are forbidden from use. As well as having 4 of them.

 

As for optane thats only in certain enterprise systems. Consumer systems its storage only basically.

 

Any reason for so much ram btw?

My daily driver is Archlinux (btw), which I typically run without cache. Currently I do have 2 paired 8 GB dimms for 16 total.

 

This is the ProDesk, so it's not a consumer model. Reading the spec sheet does seem to indicate it should support Optane dimms as a cache accelerator.

 

This seems like a nice option to have, and upting to 64Gb would allow for better VM performance overall.

It stil used a comsumer 8700 and Q370 chipset. Optane DIMMs requires a Xeon Scalable processor. The ProDesk supports Optane m.2 modules, it doesn’t support Optane DIMMs

Still a consumer platform. Prodesk is just another name as this just uses a slightly altered h370 chipset.

 

You can use optane as cache your system can support that IF hp allows it. Which is never a given with them.

 

You are better off having ram as optane ISNT ram its a cache. A very fast cache but not a replacement.
