Issue overclocking memory 680m sli


Recommended Posts

Hey guys

I have an Alienware M18x r2 and I'm having an issue overclocking the memory past 400mhz using Msi Afterburner. I'm using svl7s 1.05ov vbios. My machine spec is:

3940xm cpu - triple pipe neatsink

Dell 680m sli

16gb ram 1600mhz

Evo 840 pro 250gb

Stock 330w power brick

Has anyone else had the same issue overclocking the memory? My understanding is you can overclock past 400mhz on the memory with stock vbios. Is this correct?

Any help would be greatly appreciated.

680M memory chips quality is not flat line unfortunately- mine went up to 600MHz in the afterburner but mine friend's one reaches 450 at the very most. Do check the thermalpads on the chips, that may help to some extent
