Google and Facebook report a few unreliable CPU cores out of thousands of systems. Meaning maybe a 1/10,000 rate of repeatable CPU errors. https://www.cs.toronto.edu/~bianca/papers/sigmetrics09.pdf https://www.cs.toronto.edu/~bianca/papers/sigmetrics09.pdf Google reports 8% of DIMMs being affected by errors. While the differences in metrics prevent comparing the two things directly it seems that DRAM errors are more common than CPU errors.
