Got gifted a i7 5820k and I'm currently shopping around for parts to make this cpu work. I can across a problem and that is finding the budget for it..
Anyways I managed to find a 8x2 ddr4 pc 2400 for $60 and on that same store they have an identical ram stick that's priced at $120. The only difference between the two sick is that the cheaper one says udimm and the other says dimm. I tried to google the difference between udimm and dimm but I failed to find out what makes the other one cost so much more than the other. Does the dimm version overclock and the other can't? Does udimm limit the overclock potential of the cpu? Is it hard to find a mobo that would support udimm than dimm or does all mobo support both ram types?
Been out of the loop for a while, still running a q6600 so forgive my ignorance.

Post the links for the two.

I dont see the difference between the two. Why one is considerably more expensive than the other (other than shipping time) I dont know.
Grab 2 of the cheaper set, as the 5820k requires 4 sticks of ram.
Alternatively, find a 2x4GB set that suits your needs and grab 2 sets if you dont want to go to 32GB.
And to answer your question of DIMM vs UDIMM, the first simply states that it is part of the Dual Inline Memory Module technology, which has basically been in use since ye olden (i486 and the like) days of personal computers. UDIMM (Unregistered DIMM) is a subset of the technology that basically states the ram doesnt have anything between the memory chips and the memory controller (an extra pair of chips for ECC, a register chip, buffers of some kind, or special voltage requirements). It is a bog-standard baseline ram stick.

Are you saying that the system won't run if I only plan to run 2 sticks?
>ddr4 for a non Skylake CPU

It will run, but performance will take a hit. How much of a hit depends on what program you are running. Tasks that have a shitton of memory transfers will see a bigger hit going from quad to dual channel than tasks that have minimal memory transfers.
This is for DDR3 on a 3960X, but the same principles apply.

Blame intel for making Haswell-E exclusively DDR4. It doesnt help that all of the Haswell-E i7s are essentially 8C xeons that failed validation at their intended specs.

Would you consider getting a this ddr4 2400 4x8gb at this price or am I better off getting something along the lines of ddr4 3000 4x4gb at the similar cost?
>>50785810
Well, in this case I'd suggest getting the 4x8GB 2400 as it would have superior capacity, and DDR4 performance doesnt really scale well.
And if you need to squeeze more memory performance out of it for whatever reason, you can always overclock the ram further.

Just get a 4x4GB quad channel kit.

The kit seems to cost more, seems like kits are harder to find at a decent price, much less a bargain. Is there any real world benefits other than a company saying it works well together?
