VGABios overclocking

Hey guys, ive got RBE and ATI winflash and im a little new to this

I just want to get advice of what a good ratio is between clocks/voltage is

my current values are 669mhz(core) 829mhz (mem)/ 1.214 V

im wondering how much i should set my V up Per 50mhz increase.

almost reminds me of my algebra 2 class :P (i knew i should of paid attention)

well it depends basically you can go up the first 2 x 50mhz steps without any increase in voltage the best way to figure out the correct settings is to search for similar oc.. there is no method that will allow you to calculate freq/volt ratio so just oc it with the stock volts to the limit then add some more volts make it stable and so on.. also you should edit the fan settings rbe has some cool fan settings editing options try those to to keep ur vga nice and cool

kk, well ive gotten my my clocks/volts ratio pretty good

but i have my fan pumping 100% all the time, idles around 44C and when playing crysis its high points are 67 68 C

a little warm but i like it

67-68 C under heavy load is not too warm at all. That's a good range to have in a gaming experience.

yeah anything under.. 75C is good

yeah, im just used to seeing 40-45C full load when gaming, ill just have to get used to it then.

the stock cooler on my sapphire 4850 was an absolute piece of shit.
temps were idle 45˚C and gaming 75-80˚C.

i replaced this tiny, shitty hunk of thick aluminum with a coolink "gfxchilla" (which btw is much cheaper than it competitors and includes like, 23 ram sinks) and now temps are 10˚ less at idle and an astonishing 25-30˚ less under heavy load.

as you can see i am overclocking substantially without a mod and i have not seen the gpu get over 50˚C since the new cooler but summer may be a slightly different story.

and don't get the idea that it's just fine to run your gfx card at 75˚C!. i don't care if it's within spec, temps like that will shorten the life of the chip for sure...

nice temp difference between the to also u're righy the stock hs... it's pretty worthless on those single slot 4850's

that DOES sound pretty damn good, Ive always wondered about how good it was,
