The mining frame arrived and I assembled it The hard drives have also arrived. Here is a picture of the assembled frame with a GPU that I used to adjust the height of the metal bar used to support the PCIe slot bracket side of the GPU. The frame is new but at a very low cost. GPU mining equipment is on sale with significant price cuts.
Here is a close up shot of the GPU. The camera autoflash worked this time.
I ordered a PowerColor Red Dragon Vega 56.
It comes with AMD Anniversary Game Code Deal which has Tom Clancy's the Division 2 Gold and World War Z which is a bonus.
Main reason is it is a 2 slot high Vega based GPU, and Performance/Price.
I cannot purchase any RX Vega 64 Liquid GPU's new.
I have no time or desire to buy RX Vega 64 reference GPU's and spend extra time and effort to watercool them, and risk voiding a warranty.
It was time for me to move on from purchasing any more used R9 Fury X/Fury/Nano GPU's.
I am hoping it will have Samsung HBM2, but that is a lottery with these GPU's. Some have Samsung and some have Hynix Memory.
I will be testing the GPU as soon as it arrives and if I like it I will be looking for some more.
I will be using the Sapphire R9 280X on this builld for basic display output.
I decided to get a custom backplate made for the R9 280x GPU.
I had the backplate design made to match the backplate on my Sapphire HD7970 OC 6GB Vapor-X GPU.
Here is a picture of the backplate design, the 6 cututs at the top are to allow viewing the GGPU activity LED's:
Here is the R9280x with backplate fitted running a compute job:
Testing one of these for Medusa today:
AMD Radeon™ R9 390X Double Dissipation Black Edition - R9-390X-8DB6
Next GPU purchased for Medusa - an XFX R9 Fury Triple Dissipation.
I normally would not purchase a > 2 slot GPU but this one is interesting.
