Except that the memory chips and motherboards also need to support ECC
- marcan_42 5y agoECC costs $0 to support in motherboards (8 extra traces per DIMM slot; traces are free). Memory is where the consumer gets to choose whether to spend extra on ECC or not. There is absolutely no reason why consumers should be forced to pay extra for a CPU to get ECC when they are literally getting the same piece of silicon.
- jeffbee 5y agoIt's odd how indifferent you are being about the energy costs of ECC. Memory now dominates the energy story of many systems. Filling an x86 cache line from DDR4 costs 1000x as much energy as a double-precision multiplication operation. ECC memory costs 12.5% more energy. That's a big, big difference.
- marcan_42 5y agoI'm not saying everyone should use ECC, I'm saying ECC should be an option for everyone.
