Hello everyone,

I need advice on a new system build.

What I have already:
- CPU 4930k

What I want:
- Inexpensive system (less than £1,000) that will be used for gaming, video editing and as a virtualization lab.
- I need to OC from 3.4 to 4.0
- Need motherboard that supports 64GB RAM.

When I went to pcpartpicker.com to select parts it got a bit confusing. It shows I can use DDR4 memory even though I have read the 4930K was DDR3 only.

Your help is greatly appreciated.

I think that you are misreading it.

There are almost 3 'flavours' of DDR3.

There's DDR3L running at 1.35V (nominally for skylake).
And then there are 2 DDR3's done running at 1.5 (sandy bridge and onwards) and 1.65 (and higher) for older processors.

Now, memory can run faster if it is at a higher voltage (until it fails), or it can run slower whilst using a lower voltage (until it becomes unstable).

I'd suggest you look for a a 1.5V kit, they are very common, probably more so than 1.65V.

There are some that argue that 1.65V is fine for a 1.5V specced memory controller, personally I don't buy into that, if the controller says 1.5V, Ill try and use 1.5V.

Thank you , that was the issue. As I select a mobo from list I get an error with a few that I am not sure what it means: "Some Intel X79 chipset motherboards may need a BIOS update prior to using Ivy Bridge-E CPUs"

Thank you for your help.

Can please I get confirmation regarding x99 mobo and 4930k. I am reading on intel website and others that 4930k will only works on an X79 board and the 5000 series is exclusive to the X99 board.

I purchased over 6 month ago biut never got chance to actually build. Now it seems x79 mobo are hard to find! So choices are rather limited ..
I think I am going to go with this one:
https://www.amazon.co.uk/dp/B006665HCS/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=1SAOA7M6DVI3O&coliid=I3BE68G2E93WRF

Please let me know what you think.

Is there any specific memory I should get brand and speed wise?

Thank you for your help.

memory speed will change performance only a little, so the biggest thing to my mind is to see if you can get something on the approved list for the mobo. More is better than faster.

with regards to the mobo, beggars and choosers come to mind, you'll have to take what you can get, i've looked at a couple of other shops and there's nothing showing.

A question on memory:
Selecting 2133 MHz speed RAM I get this msg:
"The G.Skill Trident X Series 16GB (2 x 8GB) DDR3-2133 Memory operating voltage of 1.6V exceeds the Intel Ivy Bridge-E CPU recommended maximum of 1.5V+5% (1.575V). This memory module may run at a reduced clock rate to meet the 1.5V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum"

Will increasing the speed of RAM by 5% by difficult? or do I need to shop around for slower speed ram?
