Got new 4850 :)

[GinG]

Well...blown away by the performance, and how games can look and run!

Changed from a x1800xt and its great.

What is the max overclock for a card like this?

 

[gareth170]

depends what 4850 u got.

a standard 4850 should do about 685-700mhz on core / 1050-1100 on memory, 9 out of 10 it'll do 685mhz with stock bios. with a mod it'll do anything between 700-750mhz on core..

my sapphire 4850 can do 750/1150 with my mod bios.

i would say start upping the core first to find the max mhz then up the memory to find the max.

Mine won't overclock at all

Probably won't go over 700mhz without modding the bios. My sapphire 4850 did 680mhz without any mods.

I have a Powercolor 4850 and i've got mine at 675/1050. I never did find out where it starts to artifact but i expect it has some more room left. I am happy with my current clocks anyway and i like to play it safe so i'm going to keep it where it is (yes, boring i know).

The performance boost is probably minimal over a stock clocked 4850 anyway i reckon.

Mine does 720/1130 with no volt-modding. I'm trying to pluck up the courage to pencil mod the GPU and aim for 800.

do it. 800 is weak sauce, you can easily get 850mhz

But I don't have a voltmeter, so I'd be doing it blind. I think there's one resistor you can draw on as much as you like with a pencil without it going over 1.4v, so I might try that.

Yeah I pencil modded mine to around 1.28V. Measured using a voltmeter and I think I short circuited somewhere while measuring. Saw sparks and a cloud of smoke. Done that a few times. Still works tho
