Problems with 50MHz 486

From what I can remember, the first batch of 50MHz 486DX chips had some serious heat issues, and I believe intel issued a recall. I am pretty certain Intel switched production of the 50MHz part over to a smaller die size to fix the problem.

50MHz parts were only popular with ISA and EISA systems. It was very hard to build a 50MHz VLB or PCI system. Therefore the 50MHz DX/2s are far more common.
