Help! I've gone over the OC!

[rive46]

Well I have a little problem, I don't have much idea about OC so I ventured without looking at much information.
I have a Sapphire HD 7950 and I did OC only on the memories, I put them at 1150 and 1700, (then I saw that the maximum allowed for this card is 1100, 1575).

After a day of use, the screen turns black. I restart and it seems like everything is fine, I see the letters of the Motherboard, I see the Windows symbol loading and then everything turns black again.

I connected another hard drive on which I have Ubuntu and without problems, I see everything perfect, that is, desktop and everything without any problem, as if nothing had happened. Then I installed the AMD Catalyst drivers for Ubuntu and the same thing happened again. When I restarted I saw the letters of the Motherboard, the Ubuntu loading process and then everything turned black.

What can happen? Does it have any solution? Thank you very much and goodbye

See the motherboard manual to do the ClearCMOS or remove the battery for a few minutes.

Thanks for the reply.

I have tried to do it, and it didn't work. When I turned it on, it asked me to change the BIOS time, so I suppose the time I had to wait for the BIOS to reset was correct, but one graphic reaches the desktop, and the other one stays black once the OS is loaded.

Any other possibility? Thanks in advance.

Edit: post folded, something is happening with my internet too :(.

In Windows, go into safe mode and lower the frequency to the graphics. What should happen is that when you restart the program you use for OC, it sets the values that failed and that's why it's not stable. You have to go into safe mode and lower the values and uncheck the option to apply OC when you restart, so that when it restarts, it sets the factory frequency.

OC is done to the core and memory but compensating it. It's like how you gain performance. Raising the memory a lot doesn't serve any purpose except for some benchmark.

You can also try putting in the last known good configuration.

Oops, sorry. I posted in a hurry that I was leaving and I thought it was OC in micro :ugly:
