[solved] freezes on Razer Core X Chroma with Lenovo T590
I bought my eGPU (Core X Chroma) after a lot of research, most of it based on this forum. It took me quite a while to stabilize it so I thought I'd share what I found. Disclaimer: I am not a hardcore gamer so I am learning this from scratch.
- Lenovo T590 (2020), i7, 16 GB with Win10 2004, x64.
- Razer Core X Chroma
- Asus GeForce GTX 1660 Super, 6GB.
- Thunderbolt cable: Belkin, 2m, 40 Gbit, Active
The initial setup greeted me with random blue screens and no performance at all, as measured by 3DMark. This was easily solved:
- Update Nvidia drivers
- update Thunderbolt driver (Lenovo)
- Update Thunderbolt firmware (Lenovo)
No more blue screens after this. Than began a frustrating period with hard freezes, sometimes on boot, sometimes after an hour. The laptop is completely unresponsive, keyboard lights static, no network, just dead. A low-level freeze. Also, graphics performance was up-and-down except when gaming when it was OK.
Research showed that this was probably related to power management issues, and after lots of fiddling this turned out to be true. What I had to do to resolve it:
- Create high-perf power scheme. This includes the famous PCIE Link State Power Management that is listed everywhere as "the" solution. For me, this setting by itself was not sufficient. I needed the rest of the the high-perf settings as well.
- Set the Nvidia power management settings to Maximum, in the Nvidia Control Panel.
Anything less than the combination of these two leads to freezes, and believed me, I tried almost all. Unfortunately, while stable, the systems runs hot. Even on idle the Nvidia card sits at 55 degrees (C) with the blowers active and noisy. Performance is good, though.
I did not have any of the other problems reported. The network through the eGPU is rock stable, as is the USB. No problems here.
So while I have a working system now, I am not quite satisfied with the end result...
thank you for sharing your experiences... I have also the Lenovo T590 and I'm thinking a lot to buy a Razer Core X... just to play some video games sometime. How is your system doing now? Do you steel experience freezing or blue screens? Please let me know as I couldn't get anywhere if the T590 is really supporting external graphic via Thunderbolt 3.
Kind regards, Matija
It's about the same. I did have a bluescreen once or twice. To be honest, if I had known all of this in advance I would not have bought the T590 + Core X, but a gaming laptop instead. But the enclosure works, and I can play the games I wanted. Even FS 2020 works with my GTX 1660, but it's right on the edge of what is possible.
still I don't understand why do you wanna change it with a gaming laptop if everything is just fine now... When playing do you use external monitor or do you play on default laptop display?
For the same money I could have bought a mid-range gaming laptop, that's why. Probably one that I could use in the office such as an MSI or Lenovo. But other than that, I'm fine now.
I use an external display on displayport.
