Relatioship of CPU clock to GPU

Postby vgbaron » Mon Nov 24, 2008 12:26 pm

Currently my GPU, 8800 GTS 640 is not overclocked. I have started to notice white flashes in certain situations. For example, starting up at a country airport in Alaska and use the hat switch to look around it spot view - get some quick white flashes. This did not happen before. Happens with the 174.74 and the 180.4x driver also.

99% of the time all is well and this is more of a "what's happening" rather than an "OMIGOD".

The flashes can be from the buss and the amount of bufferpool reserve, and, there are known issues with FSX and the airport/aircraft lights showing quick black boxes after SP2

I have sometimes exceeded the BP reserve and seen AG show spikes as I pan around the aircraft until all scenery loads... also saw that with some drivers and BP set lower

what you are seeing has nothing to do with overclocking.

Try backing down bufferpools


SP2 introduced some strange problems which tend to vary from driver to driver release

I am using driver 180.84 now

didn't think it did - good! Will try reducing the BP - not at my system - IIRC I had it up around 32M.

btw, you meant 180.48 not .84 correct?
