Safe overclocked memory and core speeds for the DDR3 6800 go on a 9860?

use coolbits to automatically detect. that should be safe.

Coolbits' auto detection is pretty conservative when it comes to the core speed, my GPU core overclocks stably at a 22% higher clockrate than the auto detection recommends. IMO The best thing to do is take it up a step at a time manually (usually 2-5MHz) using Coolbits2, before you can apply the overclock you have to tell Coolbits to perform a test - the test is a good indicator - if it fails take it back a step.

Do this for the GPU core first then the memory, keeping in mind the core overclock is more important than the memory overclock. After you've done all that run something like 3DMark through it's paces - if you notice any artifacts (graphics glitches) or your computer freezes, your overclock is still too high. Often-times the memory is the cause of this and you just need to back the memory overclock off a bit (5-10MHz), sometimes you'll need to back the GPU core overclock back a step too.

Also, consider the ambient temperature at the time you're performing these tests - try to do it when the ambient temp is the highest you'll ever be likely to operate at, and try running the notebook at load for a while (maybe in a 3D game for an hour or so) before you start testing - this'll bring the temperature up so that once you've settled on an overclock, you'll know the machine can handle it even under strain.

A lot of people have had this problem with 3DMark '03 (even when not overclocking) this was fixed for me when I installed the latest version and ran a batch script to kill unnecessary background processes, see the following post...

i hate to sound like a DOS noob but, how in the hell do i run that thing?

open up wordpad/notepad and paste the text inside, go to file "save as" for file name: (name).bat, for "save as type": "ms-dos format", exit out of word software and click on the batch file.

Why is it that coolbits will not let me overclock at all?
Everytime I run the test, even if it is on the stock settings, the test fails.

Any help?

it still just opens up in word..

i am pretty sure i had read that memory clock was more important for performance than core clock, and therefore the overclock would be more important too. can anyone confirm or deny this?

hi, does overlocking increase the graphics performance in a game, is there any need to oc when just using it for daily use, will it look better for any reason or load thigns faster?

Yeah I used to think the same thing - and it used to be true because memory bandwidth used to be more of a bottleneck with slightly older graphics cards, but now with these high end cards and the latest games which are much more demanding, the memory is no longer the biggest bottleneck - it's now the core speed.
