Just picked up an MSI R9 270x Gaming 2G, looking for some OC advice

As I mentioned in the title, I just picked this card up, and I'm looking for some advice on overclocking it.

I found a review of this card where they managed to get the GPU up to 1200MHz from the default 1120MHz at the stock voltage, and the memory up to 1590, from 1400. I was just wondering what your opinions are of this OC. This is all new to me, but I'm a quick learner ;)

Is this about the best I can expect for a safe OC? or do you think I could safely get a little more out of this card? The reviewer only managed to get an extra 3fps out of BF3 with this OC, but only raised the GPU temp to 67*C under load, from 64*C with the default clock setting.

From what I've read, a temperature anywhere between 70-80*C is generally considered safe when overclocking, so I guess my question is; what do you folks suggest would be the max I can squeeze out of this card? Anyone here have experience OC'ing this particular GPU?

Thanks,

Patrick

you should not expect to get that good of an over clock (but can hope to) because every card is different and some cards overclock great and others cant oc at all.


to oc your gpu you will need msi after burner or another gpu ocing software and a gpu benchmark such as msi kombustor

1. open msi after burner and increase the gpu clock with a large jump (30 to 50 mhz)

2. run msi kombustor if there are no artifacts repeat step one if there are artifacts move on to step 3

3. if you get artifacts you increase the core voltage by a few milvolts and slowly increase the core clock speed
4. run msi kombustor if there are artifacts increase the voltage by a small amount(increasing the voltage is option-able) and increase the clock speed by...

Aside from the current lack of interest in this topic, it seems (from the information I've been able to find), that the settings in that review are considered to be the maximum you can overclock this gpu and have it stable. I just thought I'd mention this in case someone in a similar situation to me finds this thread in the future. I don't think I can choose my own post as a solution though.

4. run msi kombustor if there are artifacts increase the voltage by a small amount(increasing the voltage is option-able) and increase the clock speed by a small amount(10 to 15 mhz) if you cant seem to get any higher clock speeds move on to step five

5. decrease the core clock by very small amounts until stable

Thanks, is increasing the voltage normally necessary? Are there any downsides to increasing the voltage? I would think my case should be fairly cool between the 2 large fans on the gpu, and the 6 fans I listed earlier inside my rig. (I also plan to get 1 or 2 fans in the bottom of the case)

I know this card is already a fairly powerful card, I'd just like to get the most out of it. I'm not an OC enthusiast (obviously ;)), I'd just like something stable.
