Support of 32 GB UDIMM modules on Core i9-9980XE, to achive 256 GB of the total memory

Jump to solution

Dear Sir or Madam,

I am writing with regard to recently announced Core i9-9980XE and the related question about its memory support.

On its ARK page its clearly stated that the maximal overall memory size is limited to 128 GB (eight modules, 16 GB each).

However, some information begins to appear, suggesting that a few memory vendors are about to release JEDEC-compliant dual-rank 32 GB Unbuffered DIMM modules, e.g. Samsung M378A4G43MB1-CTD.

Moreover, some more-or-less credible press sources suggest that even lower tire LGA1151 9th-gen CPUs would be capable of running 32 GB modules, extending the maximal memory size from 64GB to 128GB:

https://www.techpowerup.com/248582/intel-9th-gen-lga1151-processors-support-up-to-128gb-of-memory Intel 9th Gen LGA1151 Processors Support Up to 128GB of Memory | TechPowerUp

https://www.anandtech.com/show/13473/intel-to-support-128gb-of-ddr4-on-core-9th-gen-desktop-processo... Intel to Support 128GB of DDR4 on Core 9th Gen Desktop Processors

And here the main question arises: Would Core i9-9980XE be capable of handling eight 32 GB modules to provide the total memory size of 256 GB?

If so, will such support be present only on selected motherboards (with strong enough VRM sections), in particular, would Asus Prime X299-Deluxe II be capable of that? (trailing dyad in the model name is crucial)

Yours faithfully

Hello Aquagen,

 

 

Thank you for joining this Intel Community.

 

 

The information listed at https://ark.intel.com/ is the maximum memory capacity validated for this processor design. Using the system memory tested for this Intel® Processor allows you to keep optimal operation and long-term reliability of the processor. The memory controller that is integrated in the processor die controls how much memory is supported. For this reason, trying to use more memory than the recommended can produce system instability.

 

 

Using more memory may or may not work. Please contact the motherboard manufacturer to get accurate information about memory specifications.
