Hmmm..... I have no problems using an A1200 Desktop running OS3.9 with 8 Meg on a Blizzard 030 with FPU 68882 chip. But if I pinch the 32 Meg simm from an Apollo 040 and put it on the Blizzard, I get a Workbench error like you are reporting.
However, if I try the 32 meg simm on my other Blizzard 030 that does *not* have the FPU 68882 chip, I get no Workbench error report.
Hope that tells you something :-D
P.S. Thanks to your thread making me do some tests, my daughter can now play Worms The Directors Cut without the screen pausing and flashing for about 5 minutes while it loads :-) (I've put the Blizzard 030 without the FPU chip in her A1200 so that she can have the 32MB of fast memory) :pint:
