Exciting times ahead colin !
Looking at your build log, I'm sure the system is going to be a thing of beauty too. - What case will you be using ?
I had my eyes on the phanteks entho primo, however it appeared to be too limited with rad placements etc when using aio's. The cm stacker prooved to be awesome space wise with it's easy expandability, similar to a caselabs Magnum STH10 (discounting looks, quality, awesomeness etc
)
I purchased a 64 GB Crucial Kit 4*16GB CT4K16G4RFD4213 1.2V RDIMM. It is identified as the same micron memory on the QVL. (micron make the memory for crucial)
I'll probably get another kit in the coming weeks, however ddr4 is stupidly expensive at the moment. around £550 for 64gb.
COME ON OCUK !!
Ideally I'd have gone for the 32gb chips, which there are some samsung ones out in the wild, however by the time I managed to get my card out etc, they are sold. Plus now I have forgotten the product part, so am struggling to find them again
. - maybe worth a search, if you find them please say.
One thing to note, as I only currently have 4 dimm's - 2 per cpu it appears to actually be running in dual channel mode. - Looks like you have to populate all 8 slots (4 per cpu) to get the full quad channel benefit when running dual cpu's.
I'm Not sure if quad channel memory will make much of a difference for what I am doing. - I guess every little helps, especially in certain workloads.
DDR4 Ram even the best desktop stuff is still very much in it's infancy and basically sucks in comparison to higher end DDR3, transfer speed is faster however the latency/timings are very slow. I am sure this will improve over time.
I have even started to look into ways that can use SSD tech as RAM, The things that I wish todo ideally need 1tb+ of ram (not going to happen with my budget) As the applications mostly use the ram as a holding space for the calculations, not a huge amount of data (well 1tb is huge, but relatively speaking) is actually swapped around so in my mind it kind of negates some of the need for the performance ram actually gives.
It's a given that there would be a performance penalty - even if it is significant. At least the calculations could take place, currently they just cannot be performed as the dataset is too huge, unless spending £20k+ on ram (not even a remote option)
There are some products available such as
http://www.sandisk.co.uk/enterprise/ulltradimm-ssd/ which comprise a ssd onboard the dimm, however It looks like they are used only as a fast ssd interface, and not to increase the ram capacity.
Basically I actually want a reverse ram disk - maybe using something like a intel p7300, which is designed for massive throughput and extremely high amount of writes, even if the lifespan was reduced it would be massively cheaper than using actual ram. Just figuring out how todo such a thing is the trouble. I fear I maybe barking up the wrong tree, or looking at the wrong terminology.
On a brighter note what took over 24hrs on my 2600k now only takes 3hrs
