accelerating computational speed

Hi,

I'm trying to solve a big modell with a 64bit windows laptop, 2* i7 cpu and 8gb ram in radioss bulkdata. I have 20 loadcases but 10 of them are buckling analysis and therefore the calculation is running for approx. 4 days now. In the task manager, I've seen that ony 2% of the cpu is in use but 5GB of RAM because before starting the calculation, I've entered 5000 for the memory options-upper limit.

My question is know, if it is possible to accelerate the calculation by using more cpu or ram or both?

Btw. sind a few days, always the same .rs~ files are created and delated (something_s53.rs~ and something_s57.rs~ )
