Adobe, What are the rules for setting Image Cache in Prefs?

[zoozx@adobeforums.com]

Default is 4,
I work on hugh images 750 mb - 2 gigs normally and very often up to 4 gigs.
Scott told me to bump it to 8 which I did but in this thread
zoozx "Problem reading layer data error? Composite data instead? WTF" 2/11/04 1:29pm </cgi-bin/webx?13@@.2ccfc99b/14>
Chris questioned if i was using 4 like that is what I should be using, so I'm confused.
What should i be using and Why.

Thanks!

Use 4 because it appears settings higher than that are causing data corruption.

Interesting.

Mark, I have had my cache on "8" since I installed CS and have not seen any data corruption.
Does this only happen on certain machines, or have you seen it on all models?

I've seen it on my Dual G5 2 gig with X.3.2 set at 8

Not data corruption. The data in the file is fine. It's just that a
bug in the Layer Effects pattern code sometimes has an issue reading
it's own data when the cache level is greater than 4. If you're not
dealing with patterned Layer Effects, setting the cache level to 8 can
help with performance of large files.

If you have an issue reading a file, it's simple - turn the cache levels
down to 4, restart Photoshop CS and open the file.

Thank you Scott for this most useful information which I have tucked carefully into my personal "RAM" -- hoping that it won't prove to be too "R".
