No, 1.59 volts is not harmful to RAM. It falls within normal operating voltage ranges.

Your setup with 2x4GB DDR3 RAM at 1600MHz and 1.5V is within typical specifications. The voltage you mentioned (1.59V) is slightly higher than the standard 1.35–1.40V for DDR3, which could cause issues if not properly calibrated. Check your motherboard manual to confirm the correct voltage range. If it runs smoothly at that voltage, it’s likely fine, but consider adjusting it to match the recommended specs.
It seems acceptable overall. I'd be more careful about DDR4+ but okay with DDR3 values.
