MSI RTX 4070 Super Gaming X Slim White installed and working in a Dell 5820 (950w power supply)

Following the demise of my Quadro RTX4000, I am pleased with the performance of the replacement: an MSI RTX 4070 Super Gaming X Slim White.  So many recent cards in the RTX 4000 Super series are too large for the 5820.  It took some time to research the graphics cards that would fit - thank you to TechPowerUp.com for their excellent database. 

The most important piece of research was the space inside my Dell 5820.  I had to remove the top stabiliser bar and the rear GPU holder first.  I then arrived at the following maximum available space using Slot 4 for the graphics card: 330mm length x 130mm height x 50mm card width.  The other consideration can be the position of the 12 pin socket on the top of the RTX 4070 cards.

The MSI RTX 4070 Super Gaming X Slim is given as: 307 x 125 x 46 so I was confident it would fit.  The height of the card was good, but there was still a squeeze with the vertical MSI white power connector needing gentle persuasion to bend to meet my two 8 pin connectors on the 5820.


I have been very pleased with the performance of the card, especially with video editing, upscaling, etc.  I was surprised that the brush score in Corel Painter didn’t improve - which highlights my Xeon w-2145 is the weak link (brought to my attention by Chino de Oro in my first post regarding driver support for the new RTX 4070 cards).  The card is extremely quiet and the temperature remains cool.

I am looking forward to running the UserBenchmark test on my system with the new card - unfortunately, their server was full when I tried.  Hopefully, I can update this post in due course.

So my questions are:

  • Which compatible Xeon processor is the best choice for applications utilising the cpu rather than gpu?
  • I can source a W-2155 and W-2175 in the UK.  The W-2195 gets the highest scores on benchmarks, so is it the best choice for CorelDRAW, Corel Painter, etc?
  • What difference would I notice if I filled all the memory slots with 8Gb modules, taking me from 32Gb RAM to 64Gb?

    Thanks.

The CPU upgrade in your 5820 is limited to Xeon W-21XX.  Among those, taking accessibility and availability into consideration, it would narrowed down to W-2175 or W-2195.  They will increase from 25% to 50% in passmark scores respectively.  The top CPU W-2195 can be sourced for as low as £250 online.  

Intel processors W family, compatible with your 5820:

The amount of RAM you have in your PC will make a significant difference in your ability to edit videos seamlessly and efficiently.  The optimal capacity of RAM a computer needs for video editing is 32GB.  That should be sufficient to work with editing videos and having multiple programs running at the same time, without slowing down your workflow.

Your 5820 has four channel memory bus architecture.  As long as you have all four memory channels be populated with DIMMS, it will achieve the maximum memory performance.  In most cases, you might not notice the differences when upgrading to 64 GB.

Glad to hear that the selected card is working well for you.  Also, assuming you did not have to turn off any security features of the system such as Secure Boot.  For comparison, run benchmark before and after of changing PCIe slot bus numbers.  Then later, run benchmark with the W-2195 if you decide to get one.

Great progress anyhow.

Congratulations. I believe the RTX 4070 uses PCI 4.0. Does your Dell 5820 offer PCI 4.0 or PCI 3.0? 

I'm interested in getting a workstation in which to plug one of these up-to-date GPUs and I want to avoid bottlenecks.

Thank you.  I did not have secure boot selected.  I’m not sure what other security features I needed to turn off?  I have another related post regarding the lack on documentation in the 5820 manual for users with the Dell Ultraspeed NVME M2 Quad drive.  I have one of these as my boot drive.  I think it contributed to the issues I faced when changing this drive from Slot 4 to slot 2.  Thanks.

The 5820 is PCIE 3.0, but when I researched the use of PCIE 4.0 cards in PCIE 3.0 slots, the general consensus was - expect roughly a 5-10% dip in performance.  I was happy for that performance dip as it meant I didn’t need to change my computer.

If I was changing my computer I would definitely be looking at machines offering PCIE 5.0 for next level performance.

Thank you.  I do have the four 8Gb DIMMs factory installed in all four memory channels, so I will stick with 32Gb.  It makes sense to move to a W-2195 for a good boost in performance.  There is also a good resale value in my W-2145.

Hello, please tell us if you get to change your processor and if you find any improvement.

I use a similar configuration and in the future I was thinking about which processor should be the best to replace it. So the bad thing in this is that the clock speed is lower on processors with more cores, but who knows what happens in the real world.

PS: More ram is always good, I say this using 64Gb.

Hi

I won’t be changing the processor for a while, but I will update the post when I do:  a recent experience of using the onboard NVENC encoder for upscaling video to 4K saw almost all my cores reaching 80° plus, despite a lot of processing being done on the GPU. Not sure if extra RAM would have made a difference?

More RAM would help if by chance you were having performance issues or PC crashes.

At the same time, if you want to take it to 64GB, it certainly doesn't hurt.

Decide if the cost is for you.  Not that it's the only choice, but A-Tech RAM (on Amazon) has a lifetime warranty and is a great way to save $ on somewhat older machines.  I've used it for years.

Thanks for your suggestions.  My PC does not crash, but it seemed that my processor was working very hard.  I appreciate people gaming are used to seeing all their cores in the red, but this was new to me.  I have to add that my system has only been capable of upscaling since I added the RTX 4070 Super.
