Traía las de serie del OC, 1000Mhz para GPU y 1300Mhz memos
Rubikek99 a mi no me pasa nada de esto, lo he solucionado con el GPU, de todas formas tengo 14 días para devolverla, seguiré probando.
Prueba con esto:

That idle voltage is too low to handle the IMC, which is controlling the memory running at that speed (this is NOT due to defective memory modules btw), and thus the card black screens.
Another test you can do, to see (usually a few MHz beyond tho) where you will black screen, is to either run the refresh rate at 144 hz (only possible on 144 hz monitors) or find a way to LOCK the memory (and ONLY the memory) at the full 3D speeds, WITHOUT having the core running at 1000 or 947 MHz or whatever the default 3D speeds are) with the idle voltage at 0.9xx. If you can manage that, you should see massively flickering lines on the desktop, without black screening, since you will already be at a high power memory clock, instead of transitioning from 150 MHz to it.
The fix, as you found out, is to increase the GPU voltage, which ALSO increases the idle voltage to the IMC as well. (previous generation cards used separate voltages for idle clocks and 3D). This Is purely a bios/design problem. The IMC should NEVER be running at 0.9xx when the memory jumps to full speed, or, alternatively, there should be 'lesser' memory speed jumps, for when a light load is put on the GPU, so the memory doesn't jump from 150 MHz to 1250, but instead it could be 500 MHz for a very light load (like when the core goes from 300 to 450 MHz), etc.
I'd like to say THANK YOU!
You nailed my Black Screen problems on the money!
Symptoms
1: Black screen on cold boot.
2: Random Black Screen while at desktop / browsing web / youtube
3: No Black Screen Issues while gaming.
Solution
1: Upped my core voltage +25mV using MSI AB.
This upped my VDDC to 1.008V at idle and stabilized the Memory controller for those jumps from 300/150 to 450/1250 at the desktop and now no more Black Screens.
I still occasionally see one on cold boot if it happens before Windows and AB loads to set the new voltage.
So a better solution would be to be able to edit the bios and set the new voltage manually, that would fix my problem permanently.
But for now, this works 100% for me.
EDITO: Hoy llevo ya 4 BSOD, la gráfica vuelve a PCC, no se puede permitir esto con una gráfica.
donde publicastes tus resultados)... y esta mañana he vuelto a tener otro pantallazo azul al intentar ver un video de YouTube.
