Re: 32gb ram (2 x16) possible on XPS 8930

Guys, this isn't so difficult.  Open your machine.  If you have 16GB, you should see 2 x 8GB sticks.

Just note the part numbers on the ram you have and buy two more of the same 8GB sticks to fill the other two slots to get you to 32GB total.  That's the easiest and least expensive way to get to 32GB.

I bought 2 used Micron 8GB 1RX8 PC4-2666V-UA2-11 MTA8ATF1G64AZ-2G6H1 as a pair for $80 on Ebay and they work great. 

Then later if you ever want to upgrade to 64GB, which will probably be a stretch, RAM will be much cheaper then.  Never try to future proof yourself on Ram as it's always dropping in price per unit.

I would like to know if anyone has been successful running this configuration. My reason for asking is I would prefer to use on 2 of the 4 slots to give me space for future expansion should I need it.


If you read the OP already stated that they have 8Gb installed and would like to occupy 2 slots with 16GB each for a total of 32GB with the ability to upgrade later.

Why waste money purchasing 3 or 4 8GB sticks then in the future remove them to install 4 16GB sticks???

That's why the OP's question is about if they can use 2 16GB sticks in 2 slots now.

Re: XPS 8930, 32GB ram (2x16) possible?

@U2CAMEB4ME 

Please re-read my reply.  I never said to buy 3 or 4  8GB sticks - I said to buy 2.

Firstly 32GB is ALOT of ram, and unless someone is doing some extremely extraordinary work, 64GB is is not needed for 99.9% of the applications of today. Frankly, if someone has a need for 64GB of Ram, the 8930 is not the base rig to be starting with anyway.  I do 1080HD and 4K video editing and have never ran into an issue with headroom on my SSD equipped machine. Frankly, if he doesn't have a SSD that would be a far better performance investment anyway.

That said, RAM is always getting cheaper over time. If his needs today and for the foreseeable future is 32GB, he is much better off filling the two empty slots and saving the money now for the eventual upgrade down the road to 64GB, which no doubt will be sitting in a completely different machine when that time comes.

The strategy to dump now and go with 2 x 16GB in an effort to "future-proof" doesn't make financial sense. In the near term, that angle will end up costing $200 to $300 vs 1/3 to 1/4 of that to get to 32GB now that should cover just about any use for the perceived useful life of the 8930.  If he does end up keeping the machine for 4 or 5 years, and decides then to upgrade it, the Ram then will cost less than half what it is today.  But frankly, I'd guess then, the similar build will come standard with 32GB and we will be talking about looking at 64GB and contemplating 128GB down the road all for the same inflation adjusted cost he paid for his current machine.

Again, the key point is, with the cost of RAM always falling, it never makes sense to buy larger sticks to leave slots open to "Future Proof", unless the ultimate need is now.

That's my opinion after contemplating the same line of thinking, and what worked for me. You are entitled to your opinion.

I did not buy the memory yet. My computer came with 8gb of 2666 MHz memory. I think the one in the photo is 3000 MHz. I also don’t expect it to run faster than 2666 MHz. When I do purchase and install it I will post my results. 


If it is one 8GB stick he would need to purchase 3 more 8GB sticks.

If it is two 4GB sticks he would need to purchase 4 8GB sticks.

The key point is the OP's question???

Can two slots occupy 16gb sticks for each slot???

Because the specs do not have that configuration listed.

Re: 32gb ram (2 x16) possible on XPS 8930

I stand corrected - I thought he said he currently had two sticks of 8GB.

To answer the question, the XPS 8930 Setup & Spec's Guide says the machine is 64GB capable, as I indirectly alluded to earlier - As I contemplated that upgrade myself and settled on 32GB, once I got the sticker shock.

Page 20 states 4 x 16GB

Configuration
Slot  DIMM1 DIMM2 DIMM3 DIMM4
  8 GB =  4 GB / 4 GB
16 GB =  8 GB / 8 GB
24 GB =  4 GB / 4 GB / 8 GB / 8 GB
32 GB =  8 GB / 8 GB / 8 GB / 8 GB
64 GB =16 GB / 16 GB / 16 GB / 16 GB

What is happening with ram prices? Why did they get so expensive and why would they go back down, if they ever do ? 

Dell XPS 8920 silver edition
7th gen i7 Intel CPU
Samsung 850 evo SSD for boot
Added front fan
16gb of memory
AMD video/graphic card

Re: 32gb ram (2 x16) possible on XPS 8930

Here is a link to a discussion from last year that actually speaks more to your question.

RAM & RAM Slots

According to a knowledgeable poster in that thread, the Dell Service Manual RAM Matrix is [profanity].

Perhaps there is some useful information for you in that link. This poster was doing 16  8  16  8 for 48 GB total. Unfortunately, they never reported back.

Re: 32gb ram (2 x16) possible on XPS 8930

16 / 8 / 16 / 8  for 48GB is not a configuration that is recommended in the Setup Manual, so there is a good likelihood it will not work.

I'm not sure how the poster you referenced could possibly blame Dell if configuration NOT recommended ends up not working?

Configuration
Slot  DIMM1 DIMM2 DIMM3 DIMM4
  8 GB =  4 GB / 4 GB
16 GB =  8 GB / 8 GB
24 GB =  4 GB / 4 GB / 8 GB / 8 GB
32 GB =  8 GB / 8 GB / 8 GB / 8 GB
64 GB =16 GB / 16 GB / 16 GB / 16 GB

I don't think the poster I referenced was blaming Dell for anything. They were asking the Community if configurations other than those depicted in the Dell recommended Memory Configuration Matrix would work. The answer they got was "yes, as long as you have matched pairs" (paraphrasing).

Re: 32gb ram (2 x16) possible on XPS 8930

@mr_archer The configuration in your post (although correct for memory configuration) does not match the configuration on page 20 of the XPS 8930 Setup and Specification. Look at the 8GB and 16GB configurations, the Dell document states the DIMMs should be in slots DIMM1 and DIMM3. The Dell document is incorrect. The configuration information and the note in the XPS 8930 Service Manual is also incorrect. For both the 8GB and 18GB configurations the DIMMs should be in slots DIMM1 and DIMM2. Dell630i is correct, the Dell RAM matrix has been incorrect in the XPS 8910. XPS 8920, and now the XPS 8930.

Dell does not list all working configurations. Dell even builds systems with a single DIMM which is not in Dell's own documentation. No one can blame Dell if a configuration Dell has not listed does not work, but folks here have gotten other configurations to work (32GB using two 16GB DIMMs).
