Okay, jokes aside, i need your help. I'm planning to get my hands on an r9 390, and i'm wondering about three things. First of all, which of the cards are better for stock config clocking? I know the MSI one dominates in therms of hard overclocking, but i suspect there's a lot of voltage clocking involved there. I've broken one gpu on that, and don't want to risk it. So, which model will be the best?
And secondly, i've noticed that the sapphire version consumes as much as 370w of power in STOCK config? That's a huge difference from the MSI one who according to my sources use 275w.
Thidly, what increase in voltages can i expect to see from a stock configuration overclock?
I'd love to hear some answers. And i am aware they will be general, due to our old pal "silicone lottery", so don't worry about that.
Thanks in advance.
Well, there's no way the Sapphire consumes 370W at stock. I doubt the card can pull that much sustained wattage at all, even when overclocked. You'd need a beefier PCB for that kind of stuff. Now you might see spikes of power usage sometimes that go really high, but those are momentary and you shouldn't pay attention. I'd think all 390 cards will consume roughly the same amount of power, seeing as the core is unchanged. When variations in voltage and clocks are taken into account, of course.
Regarding overclocking at stock volts... Don't even factor that into your decision. It's 100% random. Some say the MSI cards tend to overclock better, but I'd say no. It's random as always, as is overclocking in general. You can expect something in the 1100-1150MHz range at stock volts, most cards do something like that.
Also, what do you mean about seeing an increase in voltages from a stock configuration overclock? The way I understand it is you want to know how far you can push your overvolt/overclock at with stock cooling? If so, the Sapphire cards arguably have the best cooler. Throw +100mV at it (The max Afterburner allows) and it's still ok. The MSI cooler is really good too, but MSI seems to have screwed up with their TIM application, so be aware of that, especially if, like me, you don't like tinkering with your shiny new card. XFX and Powercolor are fine choices too. I would just stay away from Gigabyte for the 300 series. That cooler of theirs seems awful and they're voltage locked, so... Yeah.
