Buying RAM - I Have No Idea

Thanks in advance.

PC HP Z240T 8gb DDR4 2133MHz

I went on CEX and bought 1x 8GB PC17000 DDR4 2133MHz 288pin (the receipt states 240 pin on one line, and then 288 pin on the other.)

However, it doesn't fit… the notch is out by 1cm.

If I could post a photo I would.

Any ideas or direct links to what I need please? I'm only after 4 or 8GB.

    either you tried it the wrong way (flip it). Or your motherboard is not DDR4.. (what's your motherboard?)

      • e: Looks like there's multiple models with a similar-ish name so if you have the one with a Skylake-era CPU then that's DDR4. Do you have a serial number you can punch into the HP website?

      According to HP the Z240 tower uses DDR4-2133 non-ECC RAM.

      So the OP was right about what he asked for. What he needs to check is whether CEX made the mistake. Given the confusion on the receipt as to whether its 240 pin or 288 pin it is clear they were confused. He needs to look at the label on the RAM and look up and see what they gave him.

      OP, tell us what's on it, and we can translate if necessary.

      • I'm pretty sure i tried flipping it, but hilarious if that's all it is..

        What I received - Corsair Dominator Platinum CMD16GX3M2A2133C9
        16GB (2x8gb) 2133mhz 9-11-11-31 1.65v ver4.29 428246 141800389

        So already it seems they have sent me 16gb in error..

          That is DDR3-2133.

          You needed DDR4-2133.

          They made the mistake, not you.

          Images of the Z240 tower motherboard show it as having 4 RAM slots. The spec says it came with 1x 4GB DDR4-2133. To go to 8GB you only need to buy another 1x 4GB DDR4-2133 RAM stick, and plug it into the other same colour RAM slot. That would also give you the additional speed of having dual-channel RAM.

          If you wanted to you could go bigger than 8GB, by either buying more RAM to go in the other slots, or buying a matching pair of bigger RAM sticks.

          • @GordonD: Gordon to the rescue. Cheers.

            These are my specs

            HP Z240T ZH3.4 8GB/1TB PC Intel i7-6700, 1TB 7200 RPM SATA, DVD RW SM, 8GB DDR4, NVD Qdro P600

            • @rayallenfanau:

              8GB DDR4

              Open it up. Look to see if that is 1x 8GB RAM stick, or 2x 4GB RAM sticks. See if there are more empty RAM slots. Purchase additional RAM accordingly to either fill up the matching same colour empty slot, or occupy the empty slots.

              • @GordonD: Inside is 8gb with 3 slots remaining.

                I’m keen to double it.

                • @rayallenfanau: So get another 8GB DDR4-2133 RAM stick, and put it in the other same colour slot. By that I mean if the one you have is in slot 1, put the additional one in slot 3. If its in slot 2 put the new one in slot 4. That'll get you the faster speed of dual channel RAM as well as twice as much RAM.

                  • @GordonD: Thanks for confirming the plan I had 😊

                      @rayallenfanau: Just did a search on ebay for 8GB DDR4-2133 RAM. What do you know, but CEX has got them for $10. At that price I'd buy a pair so I knew they matched and I absolutely would get dual channel working.

                      At that price I'd probably buy 4, and go to 32GB of RAM.

      • According to HP the Z240 tower uses DDR4-2133 non-ECC RAM.

        I've now found multiple different versions of the damn thing, but this manual definitely says DDR3 on page 53.

        @rayallenfanau do you have a serial number you can punch in on https://support.hp.com/lt-en/product/details/hp-z240-tower-w… and confirm your exact specs?

          The part number on the RAM he's been sold says its DDR3. It doesn't physically fit. The key is in the wrong place. So HIS MOTHERBOARD requires DDR4.

          It doesn't help when a manufacturer uses the same model number for quite different spec products.

          • @GordonD: Yea fair. From their other response they've got an i7-6700 which is hopefully DDR4 (or DDR3L… are those even available in DIMM format?) anyway. …now to see if there's any way to delete my wrong comments

    Sounds like this is the least of your problems.

    OP,
    while you are at it, get yourself an SSD. e.g. $15 here https://www.ebay.com.au/itm/204723664177

    You can still keep the old drive for large data (movies etc) but install Windows (I'm going to assume you run that) and your apps on the SSD,
    and along with the RAM upgrade it will feel like a new computer.

    This looks like what OP bought:

    It is cheap enough for new RAM on Amazon, if you have Prime or can make up a $59 order:

    • Thanks

      I have these plans when the PC is not required for my partner’s work - because knowing me, something won’t work and I’ll end up calling MrIT.

      Thanks for the RAM on Amazon. Can I use that despite my system using 2133mhz?

        It is just a max speed.

    • while you are at it, get yourself an SSD

      Great idea. But the problem with THAT SSD is how to connect it to the OP's system. The OP's motherboard has no M.2 sockets. It could be fitted into a PCIe to M.2 adapter plugged into one of the expansion slots, but its unlikely that PC's BIOS will support booting off it, so he won't be able to replace his HDD with it.

      The OP is right to be concerned that "it won't work".

      What would be a good idea would be replacing the SATA HDD with a 2.5" SATA SSD. A SATA SSD is a 5x faster than a SATA HDD, and can be swapped for it. But its going to cost more than $15. OP's choice as to whether its worth it. Prices would start at about $70 for one to replace the OP's 1TB HDD, and he'd be very pleasantly surprised about how much quicker the PC would be. It'd be a lot bigger improvement than more RAM. All he'd need to do is image his current HDD onto the SSD, then swap the new one for the old. Lots of SATA SSDs come with the imaging software required.

      • Google said it takes MVMe. What makes you think not? 6th (or 7th) gen Intel, it should. And DDR4.
        Of course OP would check first.

        Given the budget, adding a smaller m.2 SSD makes more sense than replacing the whole 1TB.

        • As another poster found, there's lots of different variations of motherboard that go into PCs that HP puts the Z240 label on. So the specs vary wildly according to which one you're looking at. I believe the one the OP has doesn't have an M.2 socket. As you say, the OP could check that. With further thought I'll agree though that the BIOS might support booting off one … if there's a way to plug it in.

          Migrating across from a SATA HDD to an NVMe SSD might be something you or I could do. But the OP admits they aren't a PC expert.

  • Look for the wooly ones with the curly horns that all the sheep are flirting with.
