Quick Question Regarding Coolbits

[Mobius 1]

My system spec is in my signature. Here is a screenshot of the overclocking panel (i installed the coolbits reg key). My question is, do you guys overclock your card manually or do you put it on auto? Will i damage my card if i put it on auto? Or will i be ok? Thanks

Thanks guys, i didn't wanna break my card as atm i cant afford another one. But this advice is good and i will take it Gonna try it now

Sorry for the double post guys. But i had done what you said, put it on manual overclocking, then i clicked detect optimal frequencies. So i said apply changes on restart, I restarted. Everything went fine, it booted into windows. I then proceed to play oblivion. No problems there. I then have a go with day of defeat source. This is where i had problems, i got artifacting on a map, loads of colours etc. What should i do about it? Just set it back to default? I hope i havent broke it!

Set it back to default, see if that plays fine and just leave it at that.

It's not worth messing with if you really cannot afford to break the card, it is plenty fast at stock.

Yeh i think i'll leave it at default. Funny how it worked for one game but not the other, just wanted to have a play about as i havent overclocked anything yet, and that seemed the easiest part of the pc to overclock. Do you think i have damaged the card?

It detected mine at (i think) 490mhz and 130ghz :/

I don't think so, reset it to default and play the game and map where it last failed.

I also had to lower my overclock, auto overclock suggested 490Mhz on my 7800GT but that gave me corruption in F.E.A.R. so I had to lower it to 480Mhz but that gave me a lockup in TW2006 so now it's at 470Mhz

Thanks for the advice.. to be honest, even if i did lower the clock settings say, 10mhz or something (from optimum frequencies). Would that even give a noticeable boost to how fast the games play? :-/

Edit: Retried the same map on DoD:S and it seems to be fine.

Have a look at these clockspeed scaling articles:

There are several clockspeed increases that are important and the increase in speed isn't linear.

Those charts are pointing towards positive effects? Will it also reduce the life of the card?

Its a port of Blue curve. But looks nicer.

Yes, overclocking makes the card faster, what I meant by it is that the increase isn't linear, there is no increase in speed between ~450Mhz and ~472Mhz or between 475Mhz and nearly 500Mhz.

So your aim should be 450Mhz or 475Mhz

Ah thankyou, you've cleared that up for me, I was a bit stumped tbh. Lol.

Will the life of my card be reduced a lot if i turn the core clock up to 450mhz? Also, what about the memory clock? leave that the same i assume

Ihave never had a videocard fail on me and I had a 6800NU card overclocked and unlocked for well well over a year, main thing is as soon as you see graphical distorsions and sparklies you reduce the overclock.

I can't possibly tell you what is best for your card as all cards are diffferent.

What are the stock clockspeeds of your card?

I see.. so my card could differ from another card with the same speeds etc? I am at 430mhz and 1.20ghz.
