XPS 8960, installed memory cards

We can't tell you how many RAM modules are installed.  If you're looking at Dell's sales page, it should tell you how much RAM is installed. In this example, the XPS 8960 has 32 GB of DDR5 RAM, on one single 32 GB module (1x32GB):

XPS 8960 has two slots for DDR5 RAM, with max of 64 GB, eg, a 32 GB module in each slot. You can see the supported RAM configs here.  (NOTE: "supported" means Dell tested/validated those configs, but some other (unlisted) configs may also work, but haven't been tested by Dell, but not exceeding 64 GB total.)

Keep in mind that it's preferable to have two matched modules installed, eg 2x 16 GB, rather than 1x 32 GB.  A matched pair will run in dual-channel mode which is faster and more efficient than one module, which will only run in single-channel mode.

@RoHe​ Thanks so much for your reply. At present I link an old XPS 8500 i7 16 gig and XPS 8930 i7 64 gig together (SPDIF) but my demands are more than these two can cope together. Each XPS runs a DAW, (8500 Cubase 12 Pro) (8930 Cubase 13 Pro) for Orchestral composing basically dividing the orchestra into two sections. My idea is to have one solid tower ideally 128 gig? Thinking about the 8960-7605 which has a $400 discount or the 8960-7244 with the max memory installed. 

The free CPU-Z utility under tab SPD will show the number of memory sticks. See in this example it is showing a drop down with Slot #4 memory stick. Click the arrow to see other slots.

@DELL-Chris M - Sounds like OP hasn't bought the PC yet.

So, while CPU-Z is a useful tool, it's hard to run it on a PC the OP doesn't already own...

@RoHe​ Thank you for giving me some excellent advice on many options to consider. The precision (discounted)7865 looks attractive with a Threadripper Pro 5945/5955, especially if I transfered three DDR4 16 gig cards from my old XPS 8930 ? The DDR 5 ram is so expensive to mess with but would be the way to go. And yes, 14th generation i7 would be the minimum. Thank You. 

Moving DDR4 RAM from your XPS 8930 depends on it's speed.  And you'd want to transfer RAM in matched pairs, so "3" is not good, use either 2 (1 pair) or 4  (2 pairs). But...

Precision 7865 can use 3200 MHz RAM. RAM in XPS 8930 is likely 2666 or 2933 MHz. So mixing slower RAM with 3200 MHz RAM will slow all of it down to the speed of the slowest, reducing performance.

You'd be better off buying additional DDR4 3200 MHz RAM for Precision 7865 from Crucial.com. If you select RAM they recommend for a specific PC model, they take it back if it doesn't work, at no cost to you.  Crucial prices are usually better than most places, too.

Just be sure to pay attention to short expiration dates on points, as explained in the Rewards FAQs. (FWIW: I got nice/better keyboard for my XPS 8930 for only a few extra dollars on top of my Rewards points...)

Hmmm, the one thing that I did not consider, the 8930 slower ram speeds. I am now having the same problem with buying a new tower with buying a good bottle of whiskey and that is having the taste buds of a connoisseur with an income of a pauper.

Such is life..

The XPS 8960 is likely less expensive than the Precision, but it will have an Intel CPU and be limited to 64 GB of RAM.

Only you can decide which model is best for your needs and budget...

@DELL-Chris M​ Appreciated, many thanks.
