Regular RAM (not ECC) with Xeon CPU

[GalactiNaut]

I’m wondering if server CPUs and motherboards can run non ECC ram, and if so, will that increase performance (even if only a little) just by the fact that it’s not ECC (frequency and size being equal)? It’s my understanding that ECC ram runs a bit slower, and for what I’m doing I don’t need it and I’d rather have the extra speed.

You can run non-ECC-Ram. Shouldn't be a problem. I highly doubt that you will notice the difference in speed though :-) But good luck anyway

 ECC is usefull for virtual machines, when you have a lot of them it really makes it more stable, in normal use no sense, there are no fast ecc memories as there is no need for them, go with standard ddr memory

Both the xeon and the motherboard need to support non-ecc ram.

If one of them needs ECC or registered memory it will not work with anything else.

ECC memory is normally much cheaper than Non - ECC memory on the market. It can be found 2 times cheaper online on sites like eBay. But they should work, if the CPU and motherboard support it.

ECC is fine, it's an optional extra like Gsync. If something doesnt support it, you lose the function. Only registered or buffered memory causes problems.

I'm running a Xeon. As long as the motherboard supports non-ECC RAM, you're fine. You can't mix ECC and Non-ECC RAM though, your computer won't POST.
