DDR4 CPU with DDR3 parts.

[daddy devito]

So a while back I started working on a computer with my father and we got a DDR3 mother board with 2 8gig sticks of DDR3 ram and we were going to get a CPU that was also DDR3 but it was sold out at the time. Now we have ordered the Intel Core i7-5820K Haswell-E 6-Core 3.3 GHz LGA 2011-v3 140W and after putting it in we learned that it was DDR4 and we have turned it on yet. I was wondering if the CPU works with the DDR3 parts.

correct, if the cpu does not have the ddr3/4 imc, it cannot run ddr3/4
thats why you dont see 2011-3 ddr3 boards

So what's my best way to go about this?

get a cpu, board and ram that work together

Remove the 5820K from the mobo

Return the 5820k and buy a 4790k

OR - Return the Mobo and RAM and buy a suitable mobo and DDR4 RAM.

Here's a link to Intel compatibility. As you can see there is no compatibility between LGA 2011 and LGA 2011-V3. Perhaps a manufacturer could have added it custom but if they don't say so then assume not.

Well then i believe that we can still return the CPU so what one could we get that is a similar price and would work with our MB and RAM?

The motherboard you linked does not support the 5820k. You need a new motherboard AND new DDR4 RAM. Or you need to return that CPU if you still can.

Look under Memory Specifications. The 5820k ONLY supports DDR4.,

Why are you aiming for "LGA 2011" anyways?

And if u actually do want that, then get an LGA-2011v3 Motherboard X99
Rather than return the CPU; everything that is for socket 2011, but not newer "V3" are old; don't buy it. And for LGA-2011, everything regarding those require DDR4.

LGA-1150 uses DDR3
LGA-1151 (Skylake) uses DDR3 or 4 (depends on Motherboard; but these CPUs support both)
