Does FreeNAS require ECC RAM?
FreeNAS Generalissimo ZFS most certainly does not require ECC. All “checksumming” of data blocks and other things are done, of course, in the software.
Do you really need ECC RAM?
You need high-end, battery-backed fully hardware RAID with onboard RAM to ensure that you don’t lose data due to a power outage, disk failure, or whatever. So no, you don’t really need ECC RAM in your workstation. The benefit simply will not justify the price.
Can you mix non-ECC and ECC RAM?
No, these will not work together. Many motherboards simply won’t work with ECC memory either.
Why does ZFS need ECC RAM?
Because it’s how a system with ECC memory responds to uncorrectable bit errors that that makes all the difference in the world. If multiple bits are corrupted within a single word, the CPU will detect the errors, but will not be able to correct them.
How much RAM do you need for FreeNAS?
How Much RAM is needed? FreeNAS requires 8 GB of RAM for the base configuration. If you are using plugins and/or jails, 12GB is a better starting point.
Will FreeNAS work with 4GB RAM?
At least 4GB of RAM. FreeNAS documentation recommends a minimum of 6GB of RAM for best performance with ZFS. We found 4GB worked just fine. (As with RAM, the more hard drives you have, the better.)
Can I use non ECC RAM in a server?
Non ECC is just fine in consumer products – AKA your core I processors and amd equivalent. I believe that some xeons these days do support non-ecc ram although is not recommended for anything serious in business. Yes Server memory is more stable and is built to be on 24/7/365 so is more reliable.
Is ECC RAM better than non ECC?
At the cost of a little money and performance, ECC RAM is many times more reliable than non-ECC RAM. And when high-value data is involved, that increase in reliability is almost always going to be worth the small monetary and performance costs. In fact, anytime it is possible to do so, we would recommend using ECC RAM.
Can you mix buffered and unbuffered RAM?
Buffered and unbuffered memory chips cannot be mixed. The design of the computer memory controller dictates whether memory must be buffered or unbuffered..
