i'm looking at getting a new PC and using my old PC as a server

here what i want can Ryzen do this, the PCI lane research I've done is giving me different information

GPU at 16 Lanes
M.2 Slot at full speed 4x
2x PCI-E M.2 drives at full speed

can ryzen do this? or do i need the HEDT version?
 
Then sadly I don't think so, it may differ between boards but I don't believe there are currently and X370 ones that can do what you want.

Using my own Gigabyte Aorus Gaming 5 as an example, you could install all of that but one of the PCI-E>M.2 adaptors would have to go in the second GPU slot which would force the GPU to run at x8 instead of x16 (although that wouldn't really affect performance on a current GPU).
 
Ryzen has 28 gen 3 lanes, 16x --> GPU, 4x M.2 and 4x(or 8 gen 2) --> PCH. If you use two M.2's the GPU would drop to 8x(have not tried this). If you need more lanes wait for the X390 Threadripper as it has 44(could be 64?) lanes.
 
this was my plan, ( of course threadripper/intel varaint can be swapped in. The plan is Extreme Quiet PC) already have the 1080Ti

all storage will be M.2 so over time upgrade/add more

My basket at Overclockers UK:

Total: £2,414.97
(includes shipping: £14.10)

A couple of questions:

  • Why buy a 1 TB and 256 GB SSD? Is 1 TB not enough, or are you using the second as a scratch drive or something? Seems like with the current state of M.2 NVMe SSDs it's better to just buy one and by the time you actually need another one they'll have come down in price a lot. Also note that the performance increase between a standard (SATA AHCI) SSD and an M.2/PCie NVMe SSD is nowhere near as big as the performance jump from an HDD to a standard SSD in real world scenarios. If you're not doing specific workloads that benefit noticeably, I wouldn't bother with more than one M.2 SSD, at least for now. Just use a standard one as a scratch drive if you need it.
  • Why buy an 1800X? If you're overclocking a 1700 will be just as good, unless you really need that extra chance of getting 50-100 MHz more. An extra ~£120 for 2.5% more raw performance (at most) is rather pointless. It looks like you have money to burn anyway but just a thought. As you say, Threadripper or X299 would probably make more sense but you haven't really explained what you're using the machine for. If it's just gaming, multiple M.2 SSDs definitely seems pointless for the cost.
 
You could run your GPU at 8x, then use the built in m.2 port for your main drive and an 8x PCI-E to M.2 adapter with 2 M.2 slots on it giving you a total of 3 M.2 drives.

My personal Ryzen setup will consist of 1x 1TB M.2 drive for the system, a 512GB M.2 drive for the 2nd M.2 slot that my Ryzen board has (Thanks MSI!) and will initially run my GPU in 16x mode, then when I get a second one run both GPU's in 8x.


You are honestly better off buying a motherboard with 2 M.2 slots, get a a larger M.2 drive and a smaller one for the 2nd slot and just running a few Sata SSD's in RAID 0 or even just JBOD for for games/etc.

  • 256GB will be os only, probably be around 40GB full, but 128GB is slower so 256GB it is. nothing else other than apps will go here
    1TB will be my mass storage drive, Games,Programming projects & Lightroom etc. further storage will be on a NAS. i could go with standard SSD, but why when i can get more perf & less cables

  • 1800x will be £ place holder for 1976X (12 cores 24 threads @4.1) or 7820X 8 cores 16 threads 4.5Ghz

Fair enough. I'd still say it makes more sense to just partition a 1 TB SSD if you want to separate OS + apps from everything else (makes sense). By the time you get close to running out of space, you can probably get a second 1 TB SSD for the current price of a 256 GB one. :)

already using over a 1TB on games :) got 4x500GB SSds atm
