Hi guys

i am thinking of oc'ing my sapphire 5850, but have some questions as to whether ..
a) would i see much improvement fps wise??

and

b) would i mess the sound card i have installed underneath it??

Reason i ask is because the only pci slot i have spare on my mobo is directly underneath the graph card, and with oc'ing the gpu would it produce more heat which would then radiate onto the soundcard???

would that effect the sound card at all??

Also if i up the fan speed on the card to 35% it gets quite noisy, which is daft really as i have it at 25% now and its as quiet as a quiet thing in the land of quiet!!

Thanks guys

Worth ocing imo. Will probably get 10-20% increased frame rates. It will only really produce more heat if you up the voltage, I think you would have to flash to an asus bios to do that. It definatley wouldnt be hot enough to do any damage to your sound card.

On the other hand, if it runs all your games at a desireable speed there isn't really any need.

I just got my asus 5850 and I'm ocing right away.
 
Do it, free performance increase, minimal risk. Your soundcard will be fine :) Just crank it up in ai overdrive til it's not stable and back it off a notch. Run vantage before and after and see the difference yourself. I got my 5770 up to 960/1300 from 850/1200 just by sliding the bars up lol.
 
Ok, ran vantage, score is==

my clocks in ati catalyst are=gpu 775 mem 1125 temp is 37 deg

there is a box with current values reading gpu 157 mem 300 ??? is that what they are running at currently or is it something completely different?

i also have msi afterburner, but the amd tool isn't working for some reason!!

thanks for the help
 
The 157 / 300 are the 2d clocks that Catalyst reverts do when its idle/doing nothing power hungry. I would think you could get 850(875?)/1150 out of your card at stock volts, msi afterburner would be able to increase volts but you would need to unlock voltage moding in afterburner.

Allso take note that msi afterburner, once set to an overclock profile(saving your clocks at 850/1150 for instance) will constantly run at that speed, temps might drop whilst idle but will be much higher than if running at 2d clocks whilst idle like Catalyst control center.

If you have sufficient cooling though, that shouldnt be too bad running an overclock profile 24/7, allthough i would recomend making a 2d clock profile in Afterburner (say 775/1100 = standard clocks for your card) so it can idle at a lower heat (and go to 2d clocks in catalyst iirc).

And dont trust vange that much, nothing will make you GPU get as hot as when running vantage. Just increase the core clock at easy 10-20hz increases and load a quick game to see how stable it is and where the temps are.

Hope that helps :]
 
Yeah thats great, thanks,

i have noticed that ati cat will only allow me to go upto== gpu 775 and mem 1125,

so i would need afterburner or either riva/amd clock to go further??

I have a CM 690 dominator case so air flow isn't a problem, i did have 2 fans on the side panel facing the mobo but have taken them out as my cpu cooler hits the top fan.

also i have tried downloading riva tuner from guru3d, downloads fine but won't install, any help on tht one would be of great help

cheers
 
If you want to get higher clocks Use MSI, but save two profiles, 1st saved with the cards default clocks the 2nd with your OC settings, then open MSI Settings and goto the Profiles tab, you will see a box for 2D and 3D, set the 2D to your default clocks from profile1 and the 3D to the OC clocks from profile2. Now MSI will take care of powerplay for you, so when not gaming the card will run at lower cooler settings, but will speed up when you launch a 3D app/game :)
 
Hmm getting frustrated with the msi afterburner, i have saved the stock settings to 2d profile, when try to save the oc'd settings for 3d apps it reverts back to the 2d settings, also even though i never upped the voltage, that for some reason jumped from 1000 to 1080?

Help!!!!!! lol
 
Ah, see you need to save two profiles, and set both the 2d and 3d clocks for each. So your stock profile is 2d:157/300 3d:725/1200, and your new profile is 2d: 157/300 3d: whatever you can get it to. Then activate the new profile. It will automatically drop down to 2d clocks as soon as you stop running games so try runing a game in windowed mode with CCC open to check what clocks it's actually running at in-game.
 
but everytime i up the clocks and save them, the clocks revert back to what they are running at when i save to a profile, so now i have 4 profiles with the same clock speeds at stock, instead of my required oc.

that make sense??
 
For the 2D clocks, dont set the low speed, you set the DEFAULT speed, for Example, a default 5850 is 725/1000, then save as number 1 and apply the profile, and Powerplay will drop your clocks for you...

I have saved profile 1= 2D, 765/1125 (TOXIC)
profile 2 = 3D, 850/1200

On the Profiles tab under Settings, i set 2D to use the 765/1125 and the 3D to use 850/1200.
When im just browsing the net, my card runs at 400/1125 (Dual Displays) and as soon as I run a game or 3D app it ramps upto 850/1200, when I close the app it fails back down to 400/1125... simples :)
 
Dude, it may seem daunting but if you research it well and follow the steps, flashing the bios isn't hard and it makes overclocking whilst keeping uber low power and and temps at idle very very easy.

Aware that this CAN be done in afterburner but it is extra baggage for your pc and doesnt seem to work with all setups.
 
Ok, i'm running afterburner, i have saved default settings into profile 1~(2d settings), when i try to save oc settings into profile 2 (3d settings) the default settings seem to be saving automatically each time i try and save, i don't know what i'm doing wrong.

Any help would be appreciated
