Need RTX 40 series (Ada Lovelace) to work in Windows 10 1507 LTSB

[lexluthermiester]

Our old GPUs are Nvidia Geforce 210. The only reason we upgraded to RTX 40 is because, in the future, we are planning to add more CNC machines (meaning that we use newer software for demanding 3D tasks) in some of our departments.

Wait, someone in your company thought it would a good idea to upgrade from GT210's to RTX 4000's?!? Your company needs to hire someone who knows what they are doing.

No, we use AutoCAD LT 98 as our primary software.

Are you kidding with that?

 

[R-T-B]

This program can run Windows 98 - 10 1511.

Are you by chance running in 32-bit windows?

If so yeah there is no way this is ever going to happen.

 

[freeagent]

They are running old equipment for certain. If I were to guess maybe from the 80s-90s.

The CNC machines, very likely.

VMs won't work because the CNC machine is communicated through a driver.

I've installed drivers on a VM, and I guess I'm not the only one here, not sure why that wouldn't work.
Here's an idea: Put the Geforce 210 next to the RTX 4, and only use the 210 with correct driver in a 1507 VM, and The RTX 4 together with unborn, future machines on host.

 

[lexluthermiester]

not sure why that wouldn't work.

CNC machining software is VERY particular about direct hardware access. VM software frequently does not play well with that kind of access.

Sort of but here's the reason. Soon we are going to upgrade our computers. We bought RTX 40s because some of our GT 210s had aged and they don't work properly. Right now most of the workstations are using i5-2500k CPU and some workstations i5-8600k with GTX 1030s. When we upgrade our computers we save money on the GPU because If we buy old GPUs It won't be good for modern hardware and modern software as we are planning to use with our future CNC machines. For now, this is a temporary configuration until when we upgrade later in this year.

This is a 64-bit version of the OS.

Most of our equipment is from 1995 to the very early 2000s

Your job's upgrade path logic is so backwards I'm amazed they're able to keep a functioning company.

Yup. Again, not working with CNC, but I have several pieces of equipment at work (a mass spectrometer and an orbitrap, among other things) that interface with their workstations via old, proprietary SCSI PCI cards with on-board controllers. They straight up do not work if the driver for that is inside a VM. Oh, the software itself runs, but the equipment starts screeching that it cannot establish a link. It is annoying, but it is what it is.

 

[R-T-B]

I'd advise RDP or some other remote desktop solution to a designated "legacy" workstation whose sole purpose is to interface with the CNC.

Beyond that, I'm out.

You're right, but have all the possible configurations and settings been completely tested?

I mean, I want to believe that they know what they're doing, but then again, if that was true we wouldn't have this thread to begin with.

This issue can't be unique. There must be others who have tried this before, people who possibly doesn't read TPU forums. Maybe some CAM forum out there?

Are you even sure if 40xx series are even supported by the software? I bet they havent even been validated so we are chasing out tails for nothing!

the LTSC version of Win 10 you are using has about 12 months of life left before being out of complete support so your buying months before you hit this headache all over again.

You sir ask the right questions, and unfortunately they seem left unanswered.

Like you say, what's the point of chasing a fix, or hack, when 1507 won't be supported next year? Or will the company just keep on running it as is, ignoring that fact? I'm not talking about running offline.

I still say the right course would have been to stock up in replacement parts for machines/PCs that were critical in their workflow. Alas, that boat has sailed.

 

[dabvflov_243]

There is but unfortunately, this method does not work properly with newer Windows 10 or 11

Re: Autocad LT98 incompatible with Windows 10

Another excellent choice :)

In general Windows 10 22H2 will go out of support as well LTSB 2015 in October 2025. When it's out of support, we have no choice other than to keep using this OS until we upgrade our CNC machines.

Could be worse. Instead of nursing along an old version of Windows 10, you could be this German railway firm that is looking for an admin for their Windows 3.11 systems running on 166 MHz PCs with a whole 8 MB of RAM that maintain "railway display boards for almost all of Germany." https://www.tomshardware.com/softwa...ed-admin-job-for-30-year-old-operating-system

The big german banks that still utilized OS/2 on their ATM network in the late 2010's were pretty bad too. I think they finally updated though.

Maan this thread sucked me in an unexpected way....binged-read almost everything. What I am really curious about is what you do with a GT210? and Autocad 98"....I mean at any point in the last few years Freecad + Blender for sculpting would wipe the floor for CNC work. Let alone Autocad 98" wouldn't even process a customer with a file made on a fairly recent version. I know this is confidential info and I don't want OP to have any harm on his workplace, so I post this purely as a rhetorical question. Also, I find it hard to believe there is no alternative for your G-code slicer, but I am no expert, so...might be totally wrong on that one.

If it ain't broke, don't fix it.

I don't want to post it on their forum because we already hired 3 different paid expert technicians and they all say that you can't use a newer Windows 10. The highest build that the software can run properly is 10 1511. One person was able to run it in 10 1903 but you can't open any files. I tried that as well and the same issue with LTSB/C 2016, 2019, and 2021.

Re: Autocad LT98 incompatible with Windows 10

I have AutoCAD LT98 running on Window 10 Pro 64 bit (version 1903) in Windows 98 compatibility mode. I used a 32 bit installer I found on the internet. I had to copy some files from an old windows XP computer with AutoCAD LT98 running on it. It seems to run flawlessly with an occasional crash...

What you really need to do is build a specific system to interface with the CNC machine. One for each. You need to order parts that are known compatible with 1507. This is not avoidable.

They create the CNC program on PC, once done they probably save it on a thumbdrive and load it into the CNC machine.

The OP's mentioning they need some drivers to talk directly to the CNC machine, makes me think that's not the case. If the drivers were needing only to upload the software to the machine, there wouldn't be a need for drivers inside a VM.

I also wonder if theyt are in the situation where all these machines can connect to the machine vs having a dedicated machine as a controller on this setup and the rest of the machines on newer windows/setups etc.

I would be under the impression of decomissioning all these old machines and keep them as short/mid term spares for the older CNC machines while replacing them with newer machines for the newer CNC/Development purposes.

It's been almost a year since I posted, but more than months ago, my employer agreed to return all of the 40-series cards. Now, we are skeptical that if we acquire a 20-series card, it will work in 1507 even though the minimum is 1709?

This is not possible. There is a way to extend Windows 8.x and possibly (completely untested as of now, you'd be the first to do it) very early 10 support to the RTX 30 series as drivers are available to some capacity, this would limit you to the RTX 3090 Ti as the newest card you could have working under this OS. The 3090 Ti is still an exceptionally capable graphics card so, I think you'll do okay - although you'll still be stuck to the now ancient r470 driver branch. Check this thread out if you feel like trying:

Nvidia's rtx drivers support windows 7, but blacklist 8.1 install.

That would be similar to the scenario discussed here: https://www.techpowerup.com/forums/threads/how-to-install-nvidia-driver-for-rtx3080-on-windows-1709.293311/page-2#post-4790827 Yeah, from what I understand, it seems really similar. Quite a lot of work, though... for something that isn't...

Just, again, be reminded that no drivers for Ada Lovelace were ever written for earlier versions of Windows, so you cannot use this method with any RTX 40 series GPU.

We have purchased one RTX 3060 and tried that driver and modded the Windows 10 driver (466.47), unfortunately, both drivers errored out code 43 on device manager and ended up returning it.


We have also purchased some AMDs RX 6000 series however 1507 has stability issues but 1511 worked perfectly.

I just read through the thread again to refresh my memory, but I thought it was already established that pretty much any solution, running Turing on 1507 included, is just kicking the can sown the road. And yeah, I don’t think that Turing supports 1507 officially. I don’t remember off the top of my head if the hack linked earlier in the thread works there. It also should be stressed again that 1507 LTSB will officially be out of support next year.
