Quick 4850 clocking question

[Jimbo Mahoney]

Do these have the clock 'lock' that the 3850 and 3870s had?

I see some reports of not being able to get above certain speeds.

If someone could let me know what is required to get around them, I'd be grateful.

I'm guessing RBE from TechPowerUp and / or ATITool?

Do these have software volt changes like the X1900 did? I'm fine with hardware mod, reading XS now...

(or you can use the AMD clocking util, but you'll loose manual fan control)

Sounds fine, since I'll be watercooling.

So don't need anything then, just AMD clocking util or third party like ATITool or RivaTuner?

Thanks guys!
