Some 386DX 16MHz Intel processors had a small bug which appeared as a software problem. The bug involved occurred when running true 32-bit code in a program such as within OS/2 2.x, UNIX/386, or Windows in Enhanced mode. The bug would cause the system to lock up and is a difficult issue to determine without having Intel actually look at the chip. Chips that passed the test, and all subsequent chips which were bug-free, were marked with a double-sigma symbol. 386DX chips that are not marked with these symbols may have not been tested by Intel and may be defective.

Comment by Grampa (webmaster[at]cpu-museum.de):

Chips having an 'IV' marking also don't have this bug.

Comment by Paul Collins (pi314aussie[at]yahoo.com):

Got one of these suckers out of an IBM PS/2 system model 60. Put it into 287 slot in a 286-20MHz M/Board. I learned that the main CPU socket and the 287co-pro socket run independantly of each other. Using utility software, I have found the 287 socket runs a 10MHz turbo, and 8MHz un-turbo, and that the main CPU socket runs at 20MHz turbo, and 8MHz un-turbo. I changed the clock-crystal from a 40MHz rock to a 50MHz rock, and now the main CPU runs at 25MHz, and the co-pro socket still runs at 10MHz. Good thing too, as the filched D80287-10 runs hot at its rated 10. I wouldn't like it to run any faster.

With the 386, Intel introduced the 'DX' - 'SX' naming system. DX stands for Double-word eXternal, SX for Single-word eXternal.
This is the first processor with the DX marking.
