Only Requiem Crashes?

[ACraigL]

Hi,

I purchased the collection on DVD and both Overture and Balck Plague worked nearly flawlessly on my system. For some reason Requiem won't stay up for more than 10 seconds without an ATIKMDAG crash.

Not sure why this one is different. Can anyone offer any advice to make this run? I paid for it -- I'd like to finish the series

Vista Ultimate 64-bit
4GB RAM, ATI 3870, Intel E8400 3Ghz

I was able to solve the issue...

I thought it may be a heat issue, so I used RivaTuner to keep the videocard fan at 100%, but that did not help -- just made my PC louder.

The secret sauce is to *underclock* the video card. Seems counter-intuitive, but there you are. My ATi 3870 is currently set to the lowest settings for GPU and Memory clocks (700MHz and 1015MHz respectively). The fan is back to auto and continues to run well.

Here's the thing... I have very high graphics settings (1440x900, everything on and maxed) and now Requiem runs fine, great even. All on an underclocked card. Go figure.

RivaTuner will help with the underclock, or if you have CCC installed, you can use the overdrive utility. Catalyst version 9.1, BTW.

Hope that helps!

On Amazon. It's called the Penumbra Collection -- all 3 on one DVD.
