Hey guys,
I recently got the opportunity to grab a Mac Pro 2010, dual CPU 3.46Ghz, 128GB ram, with a radeon RX580 8GB graphic card, and I thought, good deal! I had a Mac Pro 2010, dual CPU 3.33Ghz, 64GB ram with a Geforce GTX980 4GB graphic card, not bad either, I figured I could sell mine and use the new one, get a little bit of a boost in the graphics department.
But.
I have a dual boot Mac os Sierra and Windows 7, on different physical SSD, I simply took all my drivers to put them in the new mac, all went well, and yesterday I thought I would play a little Tomb Raider (the latest one) to check the new card, expecting beautiful graphics and good speed. Bleh.
Pixels everywhere, and the computer was lagging like it was an old pentium 1 or something. I thought, this is super weird. The setting hadn't been changed, I was running the latest AMD driver... after maybe 30 minutes, the game simply crashed with a message from windows saying that not enough graphic memory was available. Like, yeah, 8GB is not enough...
So I did a benchmark with 3DMark and got an astonishing 3300... instead of something around 13000. WTF. Was the card fried or something?
I put my GeForce back inside. Benchmark: 3000. Again, instead of 12000. This card was working perfectly last week, when it was inside the old mac pro. I never did any benchmark, though, so I can't compare, but it was running Shadow of the Tomb Raider flawlessly.
I thought, maybe that's a problem with Windows. I decided to try the Radeon card with Sierra and Blender. I got a time around 13 minutes when 2 minutes were expected.
So, bad PCIe slot? I changed the slot. Same thing. Bad RAM? I went the whole way and swapped the daughter board with both CPUs. Same result.
I went all in and swapped everything. I simply exchanged the computers. I put everything back in my old mac, and the new graphic card. Same result.
I'm at a loss here. What the heck is happening? How come two graphic cards, at least one of which I had no reason to suspect was faulty since I was using it until today without any trouble, are both failing in two different computers? Could that be software related?
I can't really test a third graphic card here, and all I have is an old PC where I put the GTX graphic card but my friend with the steam account and therefore the 3DMark access is gone for the weekend for a RPG and I need his phone for the login. So at the moment I can't test the GTX980 in another computer with 3DMark.
What could have gone wrong? Two bad graphic cards? Like that? The seller, who actually seemed really honest and kept in touch, would have sold me a dud, and just today, my own graphic card failed too?
Thanks for any suggestion! I've been trying a bunch of things (like the slot thing, the ram thing, swapping the computers...) with my friend today but I've run out of ideas...
