How To: Overclock Your AMD / ATi GPU - Page 14

post #131 of 644
Hi,

First of all I'd like to say what an awesome guide, massive thumbs up for all the time and effort you have put in.

Now to my question, I'm building up a new gaming rig, and with everything added I'll be spending in the region of £1500, now i've never done any OCing before so I'm scared to death of screwing up and ruining the whole rig, is this guide totally safe as long as I follow the steps carefully and only change settings in tiny (10mhz) amounts?

The guide is safe provided you do not increase the voltage and keep the temperatures below 90*C or so.
Increasing voltage will likely decrease the overall lifespan of the component...Not that that's really an issue for most of us who don't need our PCs to last >10 yrs but its a matter of balancing the risk vs reward. If you are happy to take the small risk, increase the voltage by all means (provided you keep below a safe figure of 1.25-1.3v you shouldn't kill anything). Don;t let that put you off, but it's the standard warning. If overclocking at stock volts does kill a component its likely it was faulty/weak in some way anyway, the only thing is that saying you have overclocked when RMAing will likely void your warranty, so its up to you whether you mention it.

Thanks for the guide m8, I however have a few questions.

Just a little bit history first.
I got my computer a year ago, at idle the GPU was at 75C, which was according to the company I bought it from totally normal, as it was a dual GPU, but only recently did I change the fan speed via CCC from 27% default to 40%, the result was amazing, dropping from 70-75C to around 43C.
I however discovered at the very beginning another increase in fan speed should be required in games, therefore I have it on 60% while gaming, which keeps the temp at less then 80 under 100% GPU usage, which is around 20 less then before.

My first attempt to OC my GPU was via Ati Overdrive, I pushed it to max (after using similliar techniques by adding 10 mhz and check temp).
And the result was very good while playing Crysis warhead, the temp just about never reached 82C at 100% usage, after that I got quite happy about the result, however, as GPU heavy as Crysis is, I couldn't really tell if there was any noticably difference.
Though a less heavy game might be easier to spot.

As how big of an improvement can one expect after increasing both with 100Mhz?

anyways, after trying your method, I had arteficts after just increasing 50Mhz, which was weird as while playing I received none, both at 50Mhz and 100Mhz.

What does this mean?
Any tips?
(yes I have done everything correctly regarding multi gpu issues.)

also, i noticed from rivatuner hardware monitor that increasing Mhz in Afterburner would increase the GPU usage before the stability test, is this normal?

Because when I increased in ati overdrive, it would only go as high, if required, and not on idle as afterburner did.

thanks for the guide, I hope you will respond!

i cant go higher than 921mhz on my 5870...

and iam new to Ati OCing dose anyone have a guide with voltages...? how much voltage i increase every 10mhz...?

thanks for the guide!

I curious about a lot of this as well. Nice guide by the way! I have downloaded the GPU tool and used it to stress test my GPU. I have also downloaded Furmark 1.8.0 and had some mixed results.

I have a XFX 5870 and have a nice stable overclock (it seems so far) at 1.187v 975/1275. It gets stable results in the GPU tool and Furmark and my games don't seem to crash. Is this a decent overclock for this card? I see others that have them clocked quite a bit higher but I can't seem to get it stable. I am afraid to up the voltage any higher than 1.200 as I am not sure what is really safe.

At which point might you want to start increasing the voltage relative to increasing the core and memory clocks? I know every card is different but a general guide must be lurking... possibly?

Another thing I wanted to mention is about the testing with GPU tool and Furmark. Furmark seems to really test your GPU more than the GPU tool does. I can significantly raise my clocks and pass a stress test in GPU tool but fail within the first few seconds of using Furmark. Is Furmark really that good of a tool to use for stress testing or does it possibly over stress? Or, the same goes for GPU tool... is it possible GPU tool doesn't stress enough?

I don't see how you could increase the voltage because i have a xfx hd 5870 and i can't adjust the voltage with afterburner. I have already unlocked voltage control.

I can adjust the voltage in MSI Afterburner... that's what I'm using as well. Great little program btw. Did you set the "EnableUnofficialOverclocking" to 1 from 0 in the MSIAfterburner.cfg file? In order to open and edit the file you will have to right click on it and open it in notepad, which is what I did. Lemme know...

Apparently the 5970 was built for 850 by 1200 mhz like the 5870 but they scaled it back for those with lesser power supplies.

http://www.tomshardware.com/reviews/...70,2474-3.html

I can get my card to 850 by 1200 stable but I have to up the voltage and am getting furmark temps of 90c.

Anyone else have a 5970 overclocked to 850x1200, if so, what voltage do you have?

I don't seem to be able to unlock the unofficial overclocking(MSI AFTERBURNER). I opened the file as stated but I dont see it in there, help.
