GPU o/c method

(or: How is Babby Formed?)

My 7850 arrived today, and like a good wee tweaker I've been benching it at stock (so far using Crysis: Warhead, Batman: AC, "Skyrim HD", 3DMark11, and Unigine Heaven 3.0. What else should I be running? I don't have Metro 2033/BF3...).

I'm itching of course to ramp up the clocks but have yet to find a guide to doing so that I'm comfortable with. (Reluctant also to assume that this discomfort means I already know what I need to.)

I kinda like this but it doesn't seem to mention temp monitoring. Whereas this guide doesn't mention benching after each incremental clock increase.

Any recommended articles out there on how to proceed safely?

U can check this one but this is for ASUS

You'll need the Asus(works on every 7850) tweak tool to overclock the core farther than 1050mhz. The 7850 uses the same PCB as the 7870, so overvolting isn't too dangerous, but you should still stay on 1.2v or lower just to be on the safe side. Start with setting the core to 1050 and running atleast two apps (Crysis and Heaven or Batman should work) for a reasonable time to check if it's stable. Then go up in 25mhz increments stability testing in between them until you start getting artifacts. Bump up voltage slightly and repeat until you've find the highest stable clocks at the highest voltage you're willing to use. After that, find the best combination between memory and core clocks the same way. If you got a properly ventilated case, temps shouldn't be an issue, only fan noise.

How is a 7850 review relevant?

Yeah I've read that thread from top to toe but it doesn't constitute a safe approach to GPU OCing. And failing to monitor temps is the last thing I'll be doing.

There must be something around that's superior to the bit-tech/OCN guides!

What do you mean with "safe approach to ocing"? You'll be seeing some crashes or artifacting regardless, that kind of goes along with pushing your hardware. The main thing is to ensure that the settings you've decided on are stable by testing a wide variety of applications for reasonable amounts of time and to not be overzealous with the voltage

Please go through the page i linked.Its about overclocking the card.
