    Hello everyone,

    I'm bringing one of my crunching rigs back to this project after swapping out some hardware. I'm trying to run my GPUs (GTX 680) as cool and energy-efficient as possible, so I'm wondering what effects people have seen when lowering the GPU memory clock and how dependent E@H is on memory clock speed. I apologize if this has been brought up before. I searched but couldn't find anything related.

    Thanks.

      Not seen anything specific on GPU memory speed apart from the general "faster is ... faster". I know that the E@H GPU apps transfer alot of data between main memory and GPU memory, more so than other Boinc apps I believe. That would point to the PCIe speed being important, maybe having a bigger impact than GPU memory speed?
