11:19 one quirk of those particular M.2 NGFF SSD adaptors is that you can often fit two of them onto the "underneath screw holes" of a dual 3.5-2.5inch bay adaptor, using some slimline M3 nuts (half nuts if you're a mechanical engineer) and some hex spacers. You need to use some brass hex standoffs and (crucially mount one upside down and the other the right way up. To do this, you'll need 2 different lengths of hex standoffs. You'll also need patience and a bucketfull of desperation, but using this method of mounting I can get 2 x 2.5inch SSDs and 2x M2 SSD under the PSU bay of a HP 8300 Elite SFF for example, handy for Proxmox because when running disk-intensive VMs you can even out the I/O load onto different disks, or RAIDZ1 or Z2 them using ZFS.
Hi. That is handy to know about. The more methods there are for securely mounting drives the better I would say. I haven't seen anyone doing this specifically but the slimline M3 bolt and nut combined with the 2x NGFF SSD adapters should give you ample storage expansion with cooling! Great job on the description, I can visualise what you did. Talking storage - I am zipping together a quick video on 5.25" Bay storage adapters (HDD, SSD, NVMe etc.). There are quite a few solid options - with not many being affordable - but the 4x U.2 NVMe or 4x M.2 NVMe hot swappable 5.25" drive bays are definitely top of my list for cool storage methods (the M.2 NVMe bays are options on the HP Z8 G5 Fury as an example). Pricey however. I usually opt for the cheapest route and that lead me to the cheap adapters like the NGFF to Sata adapter.
Great job! I am glad that was helpful. Which Quad NVMe adapter did you settle on for your Z440? If you haven't seen my overview of 4 different quad adapters, you may enjoy that also: czcams.com/video/xqg0uQ93KTg/video.html . I ran short on PCIe slots in my Z440 to install a quad adapter in the end but I am happy with the Z440's performance.
I have HP z440 machine which I got back in 2018. My setup is pretty simple: Slot1 - WiFi and Bluetooth card, Slot2 - Nvidia Quadro card, Slot5 - Primary(OS) Samsung 1TB NVMe and Slot4 - HP Z TD 256GB. Both SSDs get at least 3000 MB/s of read speed. I haven't used bifurcation as I only have 1 M.2 card on each adapter. I am not an expert, but I believe the setup is pretty balanced/correct.
Nice, your setup sounds fairly efficient - it would get everything done, and the 3000MB/s is ample for modern day tasks. Having your GPU on Slot 2 or 5 is most optimal, and the NVMes on Slot 4 and 5 is perfect. I have my Z440's PCIe utilization on the extreme end right now. Slot 1 USB C adapter, Slot 2 dual 10GbE adapter, Slot 3 Riser cable with GTX 970 vertically mounted, Slot 4 HBA (8 SATA/SAS ports), Slot 5 HP Z Turbo Drive Quad Pro, Slot 6 Wifi Card. Being a NAS build I have optimised for drive performance, not GPU performance (I mostly remote connect to it if needed). It has been working really well as my NAS and I even managed to get my 10GbE connection up to 8-9 GbE, not bad for an old workstation!
@@racerrrz Wow, you put your machine to work! The sad part is that E5-1650 v4 CPU on my machine isn't officially supported as per Win 11 processor compatibility page. I am still running Win 10 Pro, however soon planning to install Win 11 and hope MS won't stop releasing updates for unsupported devices. Good video!
@@Charkatak That is the only downside of older workstations! What you really need is to upgrade to the newer HP Z4 G4. They aren't too expensive, in fact sometimes they sell for less than the Z440 on Ebay! The HP Z4 G4 / Z6 G4 / Z8 G4 are all Windows 11 ready. I think MS did mention dropping support for Windows 10 later next year (Officially, October 14, 2025). So we will need to upgrade hardware by then unfortunately, or endure the unsupported OS like Windows 8 users are.
@@racerrrz I will look at these machine, as it sounds like a good idea! I would feel bad replacing z440 at this stage though, as it is more than enough for daily usage and 32GB of RAM is plenty. I was planning to install "slim blu-ray" drive which is compatible with z440. Was wondering if you have installed any optical drive into slim port/bay and SATA cables were included/attached to the case? I can of course open the case up and take a look...just didn't want to disconnect all the cables and remove the machine from it's spot.
@@Charkatak If you wait another year or so they will be quite affordable machines. I have the same mindset with the Z440 - but then I am using mine with TrueNAS mostly right now so I will not really be effected by Win 10 support dropping. The hardware remains capable, and with 32GB of RAM - what more could you want for daily use. In terms of Slim Blu-Ray drive - that should work just fine. There will be sata power and likely Sata data cables there already - most Z440's have the 5.25" Optical drive (likely a DVD-Writer), so it should be plug and play. I usually remove my optical drives for more storage! You can fit 1x 3.5" HDD and 2x SSDs where the 5.25" Optical drive resides. The slim one does save a bit of space at least.
This video is great for new pc builders and old pc builders alike. I'm excited for Pcie 6.0 but I don't think we will see that one motherboards for another 2 years.
Hi. I am glad you found the video useful. I am testing some new processes in the video (like hand written notes) so it's cool to see that play a role. I would be excited to just have PCIe 4.0 in the Z840 Workstation...lol. It may take a while before the new standards reach us - but then gaming hardware tends to be quick to adopt new tech.
@@EliezYT That idea sounds fair. I wonder how complex the adapter would need to be for such a conversion. If there was a way to achieve this that would remove the bottleneck on my GPU from PCIe 3.0 x16 speed limits! But yes, sadly there is no way to speed up older PCIe connectivity. At least PCIe 4.0 is backward compatible with PCIe 3.0 etc.
Since slot 6 is rarely used, I think it would be better to put the graphics card into Slot 5 (As most are double slotted nowadays). This will ensure slot 3 is not covered.
Great idea. The GPU is a bit problematic, but as you say most of them are 2 slot cards. I have not tested a 2-slot GPU in PCIe Slot 5 in the Z440. After case swapping my Z440 in the Fractal Define 7-XL I have lots of space - allowing me to fit: a USB Type C adapter on Slot 1, a 10GbE card on Slot 2, a GTX 970 connected to PCIe Slot 3 via a riser adapter, a 8 drive SAS HBA on Slot 4 and a HP Z Turbo Drive Quad Pro on Slot 5 (x4x4x4x4 NVMe adapter). I have an old wifi card on Slot 6 - but since it's only a PCI slot there isn't much else to run in there.
Hi, that sounds like a well geared Z440. What was your end use for it? How has the K2200 been treating you? My Z840 initially came supplied with a K2200 and the GPU seemed to handle every day tasks without complaint.
I picked up one of those pcie to M.2 cards. I had to play with the slot settings in BIOS to get it to work, but it works. It's nice having 10 TB of lightning fast storage at your disposal. It does go quick though!! Most top tier games are 100-150GB these days. Nine games and you just filled that 1TB drive. What's your goto racing game btw?
Nice, wait is that a 10TB NVMe or NVMes in RAID 0 to net 10TB? I have to ask haha. That's true, and game archives will just keep getting larger as graphics improves over time. I am quite impressed with the Asus Hyper M.2 adapter with 4x 2TB NVMes in RAID 0. It works really well for a game library as well as a storage drive for video editing (In case you haven't seen it: czcams.com/video/xqg0uQ93KTg/video.html). Racing games wise, anything and everything that allows racing. Right now I am on Forza Motorsport, Assetto Corsa (with content manager + mods) before that, and Forza Horizon 5 in between also. GT7 is great, but I don't own a PS5 - so that is experienced only through mates. But sim racing is the best experience these days (I use a Logitech G923 + 6-speed shifter).
so i can use 2 nvme in z440 ? im a little noob with all these info in your video but i wanna use 1 nvme for boot and second for data and ex.. is it possilbe ? and if possible what pci model i should buy if you can give me a link
Hi Monzer. Yes you will be able to use 2x NVMes in the Z440 on one PCIe slot. All you need is the M.2 NVMe SSD PCIe adapter fitted to a x16 PCIe slot - like slot 2 or 5 (sounds more complex than it really is!). In the Z440's Bios you will need to toggle either: 1) x8x8 (2x NVMes max) or 2) x4x4x4x4 (4x NVMes Max) Bifurcation (or you can select the option in HP Performance Advisor in Windows - as illustrated in the video). I am not 100% sure which adapter is the best but I am testing several PCIe adapters right now to find out! The cheapest adapter that I could recommend is the Asus Hyper M.2 V2 which is a PCIe 3.0 adapter that is well suited to the Z440: www.amazon.com/s?k=asus+hyper+m.2+v2&crid=356NM93EZG0OD&sprefix=asus+hyper+m.2+v%2Caps%2C415&ref=nb_sb_noss_2 (link may break over time).

Hey, first thing. I just wanted to tell you how I appreciate this video and your channel. I subscribed to your channel. I also appreciate the amount of effort that goes into making this video and research. Anyways, I have a few questions and suggestions. First question that I have is do you know of an easy way to identify if a motherboard supports pcie bifurcation on a motherboard and if so is there an easy way to tell if all the slots support it or only a slot. What should I look for cpu, chipset ?? Also, do you have any tips on finding pcie bifurcation motherboards for cheap? I'd really appreciate your help. Also, just a suggestion, but you should make a video regarding how to find compatible pcie bifurcation motherboards for cheap or how to find these motherboards.

The other factors that influence bifurcation include the chipset on the motherboard, and the way the manufacturer allocated the available PCIe lanes. Thus, bifurcation support is not only limited by the CPU but also by the manufacturer's selected components for the motherboard and the resulting PCIe slot configuration. To come up with a solution to quickly see which motherboards support bifurcation isn't simple to my knowledge, and the best way to check is to go to the motherboard manufacturer's website and search for a technical document for the specific motherboard. Generally they will list if it is supported and what format of bifurcation is supported (most support x8x8 but not all support x4x4x4x4). In terms of the HP workstations, the Z440, Z640, Z840 and most of the newer HP workstations do support bifurcation. The quickest way to check support is to check the Intel details for the number of CPU PCIe lanes available. If there is only 16 lanes it will likely not support bifurcation, but if there are more lanes it will be more likely that it does - pending the PCIe lane allocations (e.g. the Xeon E5-2697 V3 CPU that I have in my Z840 has 40 PCIe lanes per CPU, so 80 lanes in total). In terms of a quick list example - check this link from Asus: www.asus.com/us/support/FAQ/1037507/ . Similar resources can be found on different motherboard manufacturer websites - and although a bit complex, you could track down a system in your price range and check these technical resources to see if it suits your intended build plans. Complex! Hopefully you find some value in this. Let us know how you get on.
Hi Mickael. Yes this can work well for storage, but there are some differences compared with the mechanical drives.
