What usually is supposed to happen when you insert ECC ram into a machine that doesn't officially support it? I have a computer with an i5-3570k and a GA-Z77X-UD5H and decided to put some PC3L-12800E into it to see what would happen. I figured it wouldn't boot, but it actually works perfectly.

It might have automatically turned off except. Run some tests

it works normally, without ECC features

I'm guessing this is due to it being unbuffered?

More interesting question is what happens when you stick rdimms in a box with a xeon E3 in it.

It won't work.

As in won't boot?

Yes. The memory controller cannot address the memory because the buffer is in the way, so to speak.

FUCK. Lenovo was selling DDR4 rdimms below udimm prices for a while.

Haha you're fucked mate.

It will run, but the additional 8 bitlines and their associated memory chip used for ECC will not have a link to the memory controller and thus will not function.

Good explanation, thanks.

It creates mustard gas.
Don't do it!

>using 2x4GB + 2x2GB DDR3 1600. Frequently run low.
>have 4x4GB ECC DDR3 1333 in the other room that I thought was useless

Damn, now I'm conflicted. Do I move to 16GB and drop to 1333MHz, or stay at 12GB 1600?

Ah well. Anyone want 16GB of DDR4 RDIMM for $100?

>tfw when you need unbuffered ECC
Way too hard to find this shit... And you are asking way too much user.
I got 16GB for like 80 the other day.

100 includes shipping. 16GB registered is selling in the 150 range.

Is that a single DIMM?

It will only work if unbuffered.

It probably is, considering it's just an 1U mATX with a X3450.

* yes, it is.

It is.
