HP neglected to set the XMP profile or provide instructions to make the memory run at the rated speed. Fortunately I found out how to get into the bios and pick a XMP profile via a Google search that found a forum with this topic. I also feel that the system should have come with 32GB of memory (not 16) based on the price and the need for more memory when using Windows 11. The system itself runs great and is very fast and appears to be well built. USB disk transfer are still very slow (sometimes under 20 M/Sec) which I believe is the fault of Microsoft rather than HP but you never know. The drivers just may not be that great at this point. I also wish that the USB ports were better labeled to understand best use case for each port. I found that using all of the rear ports resulted in my USB drives disappearing so I moved two of the 5 to the ports on the top and that behavior stopped. Also, at this point not 100% sure how to get the system overclocked to the point of hitting the advertised throughput but I did kick it up a couple of points and it appeared to help.
While I'm rating 5 stars, most of what I say will be the negatives (because everything else is that good). The DRAM is very under-clocked and even if you get the exact same brand and model, HP won't support it in their managing software. You can use non-HP-sourced memory, but they treat you different. The sound, while generally low, is noticeable when the machine is placed right next to you (at the same level). Some is fan sound and some is water pumps. Not really bad, and it runs cool enough that this is not a true complaint. The graphics card is so huge that finding a 10G network card that fit in the one remaining slot was difficult. This card fit: Marvell AQtion AQC113C Controller, NICGIGA 10Gb Ethernet Adapter. This card did not fit: TRENDnet 10 Gigabit PCIe Network Adapter (chip on back stuck out 2 mm) I just used the other card in my old machine so now they all cruise at 10Gbit.
Can't say enough good about the quality of this 45L desktop. Powerful, reliable, outstanding graphics (with the 3080), and super-quiet thanks to the liquid cooling. HP service/support has also been excellent. I'm loving my decision!
So far, everything's been great. Delivery was quick and on time and the packaging was secure and quite frankly impressive. The case itself is a quality build and the internals are the cleanest looking I've seen. Very good job HP
