Is overclocking GTX570 memory dangerous?

[iNoXiouZ]

I read on another forum (overclock.net) that overclocking the memory on a GTX570 could be dangerous, apperantly a person bricked their GTX570 by pushing the memory past 2300Mhz

Any Logic to this? I thought you'd simply get artifacts or a crash if your VRAM was psuhed to hard?

I overclocked it very easily and safe when i had 570 :P

Hey, what happened to your GTX570? and what mem speed were you running?

It's no different than overclocking any other component, really, the risk is there.

I have always felt that overclocking graphics memory is slightly more risky than CPU or GPU core.

The reason being that you cant always tell that you have pushed the memory too far as you might not notice artifacts in games.
Where as a CPU thats pushed too far will cause crashes and you will notice it.

GPU memory also seems more fragile than a CPU.

I have killed more graphics cards than CPUs personally.

Thats not to say that you shouldn't overclock the GMEM, but a little caution is no bad thing.

Ok thanks for your replys guys, Do you think 2200Mhz is ok?, card will be under water, and the card was factory overclocked to 841/1682/1980. I've never noticed any artifacts at 2200Mhz mem speed

Test in Furmark burning mode,ati tool and of course Vantage
And make sure that everything is ok

Don't remember but higher than 2 k

You need to use performance tests to overclock GDDR5. You can push it beyond its stable limit and it will still look fine due to built-in error correction. The performance will rise as you overclock, but at a certain point it will fall off. You must make sure to do your testing with the heatsink/GPU warmed up to near maximum temperature as well since running the tests at a lower temperature could mean you get lower performance as the card heats up to full temperature.

I think max safe is 2300???

[afireinside]

That was me. No idea why the card took a dump. After some digging I found other people running high ram clocks without problems.

Cooling?

Running 2200 (4400) here on a PNY 570 with auto fan speed. I tried 2225 (4450) but it produced crashes in Unigine Heaven, which is my new favorite testing tool. I've run Vantage and Furmark in the past but I've found that OCs that work in those titles may not work in Heaven.

[iNoXiouZ]

Ok well I'll just keep testing and pushing until it crashes/artifacts, and then back it off abit. I also find heaven to be the most stressful program for a GPU, I can play games at 940 Core @ 1.1V but heaven is only stable upto 920 Core.

[sin0822]

i have a gigabyte 570 gtx reference card non SC. And i can do 950 core and 2111 mem and yes Unigen is what caused me problems at 1920/1080, that is why i backed down from 960 and 2120.

[bekuna]

Ive got strong desire to get back my 570

[Ccaution]

I got a slight performance drop above 1080MHz (@mem) - so you really should finetune, in order to find the actual best value. But I really don't thing you can heart the card this way. A vmem_mod might actual cut it though

hope not - my MSI is 4200 out of the box
