MarkvsK,

Depending on the processor that is installed in your computer will determine the speed.

Memory

The following table lists the available memory configuration matrix:

Memory

The XPS 8930 has four DIMM slots. Your computer supports 8 GB, 16 GB, 24 GB, 32 GB, and 64 GB UDIMM DDR4 memory (up to 2400 MHz for i3 processor and up to 2666 MHz for i5/i7/i7k processors).

Hi Jesse,

Thanks for your prompt reply.

I have an i7-8700 3.2GHz.

Question though is there any way to check what's on there already. Do I have to open the box to check or is there a way I can check on the system description?

I believe its 1x16gb but not entirely sure. Do the RAM sticks need to be the same or can I buy any on the list I mentioned above?

Thanks again for your help.

Best regards,

Mark

MarkvsK,

The memory has to be the same. You cannot mix different speeds of ram. You can open the system to look. You can look in the system Bios by starting the computer and tapping the F2 key. You can also click the link below to add your service tag, let the site detect your pc and click the configuration tab to see.

MarkvsK,

You can download and install a program like CPU-Z from https://www.cpuid.com/ to determine exactly what is install in each memory slot. Go to the program's SPD tab and select the slot # and the memory size, max. bandwidth, manufacturer, part number, and serial number will be displayed. This information will help you determine what to purchase, but you need this information first.

Hi Jesse,

Thanks for getting back to me and for the link,

From the tag I found;

Available Memory               52.19 %

Page File Size                    24,194.8MB

Available Page File            99.67 %

Virtual Memory                  24,194.8MB

Available Virtual Memory  58.27 %

ChannelA-DIMM1              8,192.0MB

ChannelB-DIMM1              8,192.0MB

Does that mean I have 2x 8Gb?

Unfortunately, it doesn't really say which stick(s) is(are) in there

Best regards,

Mark

Hi Vic,

Thanks for the post:

So I ran it and found;

ON THE MEMORY TAB:

Type: DDR4

Channel #: Dual 

Size: 16GBytes

NB Frequency: 798.0 to 3000  MHz (moves around live)

ON THE SPD TAB:

Just Slot#1 with everything greyed out

BUT ON THE AMAZING TXT REPORT I FOUND;

which unf would corroborate Jesse's tag as well!

OMG, gonna have to buy 4 x 16gb its such a crazy cost!

Any thanks for your precious help, really, to the both of you!

Enjoy the day,

Best regards,

Mark

Well spotted Vic,

Indeedo its slot #2 and slot #4, both indicate;

DDR4

8192 MB

max bandwidth DDR4-2666 (1333 MHz)

Manufacturer: Micron Technology

Part Number 8ATF1G64AZ-2G6H1

Ranks single and serial

So basically I have to buy another 4x 16gb to increase substantially my memory.

The problem I have is Excel sends "Not enough system resources to display completely" on some of my sheets and crashes. I was surprised that 16Gb RAM was not enough, given that the same sheet runs fine on my old Precision T5500 which only has 12Gb...

Not too sure what the issue might be, for all I know could be totally unrelated to RAM. 

Thanks for your help!

Best,

Mark

MarkvsK,

In CPU-Z, slot #1 is grayed out because there is no memory in that slot. If you had click on the drop-down arrow you could select another memory slot. You should see information in slots 2 and 4 and slot 3 should also be grayed out if your memory is install correctly according to Jesse's Table 2. 

Hey Koeven,

Thanks for the post. I think you have to increase RAM with exactly the same sticks as you already have (as per Jesse's post above and XPS 8930 manual), so yes I could give 32Gb a shot, adding the two same 8Gb sticks.

Unfortunately, we are still using Excel 2007, because of the VBA in there as well as an SQL interface which would both require some (heavy) additional programming.

I wasn't at all aware of the 32bit vs 64 issue in old Excels. Odd though that it worked so well on the old machine (64bit Win7 w/12Gb) but not on the XPS 8930. At home, I have an XPS 8920 where the problematic sheet work fine on Win10 (except for copy paste which heats the CPU up and often freezes whatever is going on in the sheets).

Never short of a problem with Excel... Thx for the Microsoft support link!

Best,

Mark

Mark,

Given all the issues with Excel and the cost of RAM today I would try to resolve the problem without adding more memory first. Given that you are able to run your spreadsheet on another machine with less memory I think that it is unlikely that it is a memory issue.

Hi Vic,

Thanks for the post and link.

So frustrating.

1) On my XPS 8920 / Windows 10 Pro / 16GB Ram, which you would think should be the model slightly less powerful than the XPS 8930 (the only diff is i7-7700k CPU @ 4.2 GHz), Excel 2007 doesn't crash (after opening the 8sheet) but does have a problem with copy/paste which makes the sheet hang, heats the CPU (usage up to 30%) and may freeze the sheet from time to time.

2) On my old 2011 Precision T5500 / Windows 7 Pro / 12 GB RAM, there is no problem whatsoever, you can run this massive sheet and many other instances of Excel 2007 with other stuff running simultaneously! No copy/paste issues either.

3) But my shining new XPS 8930 / Windows 10 Home / 16GB Ram - couldn't get it with a Windows 10 Pro from Dell / I would upgrade later (tho TBH, not too sure that would make any tangible diff), won't open even one single instance of Excel without these memory problems!! (at least I don't have the copy/paste issue with that one, yet...)

That link is great, going to study it in detail, try and sort both the memory issue and the copy paste issue which is really frustrating as well.

Why can't all this stuff work like its supposed to from the word go?!

Best,

Mark

I have an i5-8400 8930 that originally came configured with 8 GB of 2333 MHz ram I added two modules of 8 GB 2333 MHz ram, however, the bios will only recognize them as 2133 MHz. Is there anyway to get them to the 2333 MHz? Ripjaws V F4-2666C15D-16GVB DDR4 16GB (8GB x 2)

On this site: https://gskill.com/en/product/f4-2666c15d-16gvb it says that the SPD Speed is 2133 MHz while the Tested Speed is 2666 MHz. The SPD Speed is the information stored in an EEPROM chip on a synchronous dynamic random access memory (SDRAM) memory module that tells the BIOS the module's size, data width, speed, and voltage. In some BIOS the memory speed, voltage, etc. is adjustable but I don't think it is in the XPS 8930.

Thank you! I feel like G.Skill has taken me to the cleaners but I'll know in the future.
