Overclocking noob

[JupiteL]

I have a question that is need to know for I'm still new at this kind of stuff.

So 3 month ago my father bought me this new PC with gtx660 in it, and i only use everything at stock speed, but after I'm seeing everyone do an overclocking and the result is amazing, I'm planning to do it now

so my question is, how much clock speed does my gtx660 card, OR how do i know the maximum clock speed for a GPU until it reach the limit (i don't want to broke it)

Rrrun furmark after every little mhz increase when you start seeing wierd stuff on your screen like random lines its unstable back it up and run it couple of hours to make sure it's stable.

so, can i just raise the memory clock to +1000 with MSI after burner in a safe condition?

Not the memory clock the gpu clock but you could link the memory clock to it :)

The stock speed is speed is 980 so start at a 1000 or 990 and increase it with litlle steps from there until it's unstable.

And make sure your temps are not to high.

you might want to watch Linus' overclocking guide

it's as good of an explanation that you'll need (:

thank you very much, that's explain everything i need :)

just make sure that you don't up the voltage until it really needs it IE around 1200MHz

Okay! But I think I don't really need to change anything from the voltage yet

Don't use furmark.

Add a core offset of +20mhz as a starting point. Increase by 10mhz if it passes a run of heaven 3.0. etcetc. pretty sure linus explained it in the vid posted.

Don't forget to do the memory afterwards. You can start with a mem offset of +300 I'd say and go up in 50mhz steps.

You can't change the voltage so ignore that.

So i have my 7870 hawk on a stable overclock @ 1250MHz GPU clock and 1450MHz Mem clock. I say its stable because ive run Furmark Burn-in with no problems on air, with a max temp of 82 degrees C, for several hours. However, when gaming / browsing. Occasionally my screen flicker goes off the walls, and i have to relog into windows with script macros to regain functionality. No driver failure. None of this artifacting occurred during Furmark burn-in. So my question, WHAT THE FUCK IS HAPPENING.

Thanks in advance for any replies,

Christian

PS. also getting a pretty consistent horizontal flicker on my 2nd monitor almost at all times. one display is HDMI other is DVI (if that matters)

It means it isn't stable use another program to chek if it is stablle.
