Bitflips aren't the bottleneck in your mining rig.

No. Not worth it.

Crypto mining is inherently error-tolerant. A single bitflip in the memory might cause an invalid hash — you lose that one share. But the odds are astronomically low, and even if it happens, the cost of that lost share is pennies. You’d spend real money on ECC RAM and a compatible motherboard for what, maybe a 0.01% improvement in effective hashrate?

The bigger issues in a miner are heat, power efficiency, and GPU stability. ECC is for file servers or databases where a flipped bit could corrupt a payroll record. Your miner just needs to crunch numbers fast and retry when it fails.

If you’re worried about stability, undervolt your GPUs and put a fan on the RAM sticks. That’ll do more than ECC ever will.

Save your money for an extra GPU.
