Also make sure you connected all Motherboard Power connectors including to the CPU AUX power connectors.ĮDIT: Best way to check to see if your Vega64 is defective is by installing it on another computer. Make sure you have all GPU Power connectors connected directly from the PSU to your Vega64. PSU REQUIREMENTS - RealHardTechXīut even with a slightly underpowered PSU, the Vega64 should have started up and worked. Īccording to this Website that post various PSU minimum requirements for most AMD & nVidia GPU cards mentions for Air-cooled Vega64 you need a minimum of PSU of 700 Watts (total system use) and for Liquid-Cooled Vega64 you need a minimum PSU of 900 Watts. If you are able to run MEMTEST86 I would do that just to eliminate bad RAM Module.Īccording to AMD Specs you need a minimum PSU of 750 watts : Radeon™ RX Vega⁶⁴ Graphics | AMD. It's going to either be a very simplistic issue, or the GPU SoC itself has been damaged and thus well dead card but good luck getting the Postal Service to take responsibility for that.Īfter checking the RAM since that was also changed, it still may be a PSU issue. And again it's a similar issue to 'Bad RAM' as the Card will simply not POST., but this is more difficult to diagnose and work with for Graphics Cards.īeyond that., you can either RMA it (assuming it's still within Warranty., it should be) or take it into an Electronics Repair Store., like iFix or such. It's possible the V-BIOS has become corrupted and will need to be Re-Flashed., unlikely but possible.

it's possible that one or more of the new RAM Modules is faulty., and yes even if it's just one of them, it will prevent the ENTIRE System from Completing POST, normally with a 1 Short, and 2 Long Bleeps via the PC Speaker., but people tend not to have them connected anymore.įailing this, borrow or acquire a cheap'n'cheerful GPU that you can use as Primary and put the Vega in the Secondary Slot., just to see if the System even recognises it's there. Try running with the Original 8GB System RAM, then the New 8GB System RAM. Make sure that you've Seated it properly (take it out, and put it back in firmly) … Make sure you've connected both PCI-E Power Connectors., if you have Multiple PCI-E Power Connectors, try different combinations of the available connectors. It sounds like it's been damaged in transit., but that's not exactly something that can be diagnosed easily over-the-internet.
