Razer Core X - Power Color Radeon Vega 56 Red Dragon HBM2 8GB
The card states that it needs a 650watt PSU at the minimum - this could be my problem.
When playing on both my Windows and OSX machines, after having played for about 20-30 min., suddently the card shuts down.
External monitor shuts of and the card is missing in my device manager.
I've seen multiple people running this setup (though not the OC edition of the card) - even the bigger Vega 64 edition.
The card has an option to run two different BIOS/flashes and I've tried switching to the "cool" mode, which is supposed to clock the card down.
I even tried going into AMD Wattman to set the card to power saving mode - but no luck.
Thank you so much in advance =)
@ph4nt0m, Sorry I misread. The Razer Core X PSU should be able to handle it without issue. Was this RX Vega 56 a new card? If not I would recommend flashing the original vBIOS to make sure the card doesn't have any hardware issues.
Hi @ph4nt0m, I recently performed an eGPU build with the same PowerColor Red Dragon Vega 56 for both macOS and Windows 10. Tho my eGPU was an AKiTiO Node and provides much less power (400W) than your Razer Core X (650W), it was able to handle my stock Red Dragon Vega 56 without any issues.
I agree with @itsage to start with the Vega 56 BIOS and make sure it is at stock settings. My Red Dragon Vega 56 is stock tho I suspect even my 400W Node would be able to handle overclocked it since techpowerup lists this card at only 210W. So your 650W Core X should have plenty of power to spare for this card. (remember, recommended PS is for the entire PC, not just the GFX card).
I've tried the quiet / cool mode BIOS switch on my Red Dragon V56 and it causes stutter in games. Tho it does help to keep the fans at minimum, I'd recommend avoiding it since the Red Dragon fans aren't too loud and will often stop for total silence when not running intensive tasks. Next I would make sure the TB3 cable is not damaged before considering the Razer Core X. Do you have an extra graphics card to test in your Razer Core X to help troubleshoot the issue?
If you're interested in what kind of performance you can expect, here's link to my build: https://egpu.io/forums/builds/2019-13-macbook-pro-8th4cu-vega-56-32gbps-tb3-akitio-node-macos-10-14-6/
@cnon297, I suspected that the PSU was for the entire system.
Yesterday I took apart the whole thing, switched around the power cables, cleaned the case and sockets and voila! So far I've been able to game with out any issues! 🙌🏻
I have no idea what could have caused this, but as long as it worked 👍🏻
Thank you for your inputs and for clarifying about the PSU.
GOOD DAY TO YOU SIRS 😃
