G5 5000 Memory Config

Hello,

I recently purchased a G5 5000 and it came with 16GB via a 2 x 8 GB, DDR4, 2666 MHz/2933 MHz, UDIMM,
dual-channel config. I'm interested in upgrading to 32GB by adding another 2 x 8 GB, but this doesn't seem to be supported, according to the manual. Is this correct? I'm a little confused as the motherboard only lists using all 4 slots at higher memory configs (64GB and up). Here's what the manual has for options:

● 8 GB, 2 x 4 GB, DDR4, 2666 MHz/2933 MHz, UDIMM,
dual-channel
● 8 GB, 1 x 8 GB, DDR4, 2666 MHz/2933 MHz, UDIMM
● 16 GB, 2 x 8 GB, DDR4, 2666 MHz/2933 MHz, UDIMM,
dual-channel
● 16 GB, 1 x 16 GB, DDR4, 2666 MHz/2933 MHz, UDIMM
● 32 GB, 1 x 32 GB, DDR4, 2666 MHz/2933 MHz, UDIMM
● 32 GB, 2 x 16 GB, DDR4, 2666 MHz/2933 MHz, UDIMM,
dual-channel
● 64 GB, 2 x 32 GB, DDR4, 2666 MHz/2933 MHz, UDIMM,
dual-channel
● 64 GB, 4 x 16 GB, DDR4, 2666 MHz/2933 MHz, UDIMM,
dual-channel
● 128 GB, 4 x 32 GB, DDR4, 2666 MHz/2933 MHz, UDIMM,
dual-channel

Thanks!

    Those are only the RAM configs that Dell validated for this model. Doesn't mean 4x 8GB won't work, but Dell isn't responsible if it doesn't.

    Probably will work... YRMV!

    Ok, thank you! Will it work in Dual Channel mode, do you think? (If you had to guess.)

    If the 2 modules in a pair (same color retention clips) match each other, then RAM should run in dual channel mode if you add another 2x 8 GB.

    Keep in mind that Dell PCs can be very fussy about RAM. And some RAM may not be compatible even though the specs look right...

    @spaceghostinme  You're welcome.

    I'm sure others will have the same question, so post back and let us know how the upgrade to 4x 8 GB goes.

    HI there everyone

    I have a G5 5000 with a 16G memory module and there are 3 slots available.

    Questions:

    1. Is the max upgrade = 64G?

    2. Which ram modules are safe to install?

    3. Can I install another 2 x16G block or another single 16G block?

    G5 5000 supports: 4 GB, 8 GB, 16 GB, 32 GB modules in each slot. So the max is 128 GB, total.

    Always best to install RAM in pairs of matched modules so that it runs in "dual channel" mode which is more efficient and faster than "single channel" mode. Right now, your one module is running in single channel mode.

    What to add depends on your needs and budget. Dell hasn't validated 48 GB (3x 16 GB) in this PC model. Doesn't mean it won't work but...

    You could install one 16 GB module in the slot with matching color retention clips. Assuming the new module is a close match to the existing one, they will run in dual channel mode. And a new matched pair in the other 2 slots if you want 64 GB.

    NOTE: PC  is shipped with 3200 MHz memory. However, the memory speed is limited to 2666 MHz in computers shipped with Intel Core i3/i5 processors and 2933 MHz in computers shipped with Intel Core i7/i9 processors.

    Many users around here buy RAM from Crucial because they guarantee it works if they recommended it for a specific PC model.

    With the link ...

    - Now I know it's upgradeable to 128G
    - My PC was shipped with Intel Core i7/i9 : hence 2933 MHz in computers shipped with Intel Core i7/i9 processors.
    - The computer is shipped with 3200 MHz memory.

    FYI, in case anyone is curious, yes, you can run 4x8GB in dual channel. I ordered the RAM direct from Dell to help ensure compatibility. Arrived and installed today - good to go. Verified dual channel in the BIOS and with CPU-Z. All appears to be running well. Thanks!
