Exceptional GPU repair work
Exceptional GPU repair work – they achieved what others said couldn’t be done
I genuinely cannot praise Blackstone highly enough.
My RTX 5090 suffered a serious failure involving fire damage. Given the value of the card, I initially sent it to a specialist repair company in the UK. They dismantled and assessed it but ultimately told me that it could not be repaired.
I wasn’t prepared to give up on such an expensive GPU, so I started looking further afield and eventually found Blackstone.
What they have achieved is remarkable.
Rather than simply attempting a conventional board repair, they carried out an extremely complex transplant using a donor card. The GPU has now been successfully brought back to life and is being correctly recognised as an RTX 5090, with the full 32GB of GDDR7 memory, 512-bit memory interface, PCIe 5.0 x16 connection and the correct shader configuration all showing properly.
For context, this was a card that another professional repair company had already written off.
What impressed me most was their willingness to take on a genuinely difficult repair rather than simply saying it was uneconomical or impossible. The level of technical skill required to diagnose the failure, source or use a suitable donor board and successfully carry out this type of transplant is far beyond normal electronics repair.
If you have a high-value graphics card that has suffered serious damage, especially one that other repair companies have rejected, I would strongly recommend speaking to Blackstone before giving up on it.
Businesses with this level of specialist knowledge deserve to succeed. I suspect they are going to become very well known in the GPU repair community if they continue producing results like this.
An outstanding piece of work and a huge thank you to the Blackstone team.
Five stars without hesitation.
