Help with Overclocking

[CGurrell]

Hi guys,

 

So a while back I overclocked my Sapphire r9 280x Dual-X graphics card. The other day, I reinstalled windows onto a new SSD and it seems my clock was sent back to stock (At least that's what GPU Tweak told me). No biggie, I reinstalled GPU Tweak and the GPU Drivers (Did this right after windows install), and re-overclocked the card (Pic below).

 

I then noticed that my GPU Voltage was at 1300mV, but that I could technically increase it to 1400mV. Is this a really bad idea? Or would it be ok?

 

Thanks guys

 

EDIT: I know GPU Tweak says my card is a Matrix 7970, I think it's just a bug, GPU-Z recognises the card correctly

Is it a bad idea to change voltage? no but it's one of the more dangerous things about overclocking. But increasing it by that little amount I think you should be fine.

MSI afterburner and kombuster work really well also.

I remember that I increased it from 1.2v to 1.3v thanks to the recommendation of a friend, but he doesn't know about 1.4v as his 280x only allows 1.3v max voltage. Not sure if that changes anything

Because 1,300mV is the max doesn't mean you should put it straight there and even if you could change it to 1,400mV you'd kill the card.

Yeah I'm still a noob when it comes to overclocking I basically copied my friends OC on his 280x (he has the same one as me, Sapphire Dual-X, but not the OC version I have) and upped the core clock from 1120 to 1170, went up in 10Mhz increments (Same with memory clock), but the voltage I just put to 1300 and power to 120% as that's what his was at. Whoops

Just because you both have the same GPU doesn't mean they will OC the same, why don't you have a look on youtube for GPU OC'ing and take notes, also I think Linus has done a guide or two in regards to GPU OC'ing.

Yeah, a couple of weeks after overclocking, I realised that not all equivalent chips are created equal It's working well anyways and if I go any higher on the base clock I get some small artifacting in Valley so I think 1170 is the max mine can go
