I've decided to upgrade to the Ryzen 1800x.

I'm looking for some advice on motherboards, ram, and a new SSD drive.

I currently have SLI two 980TI's.



I would like any help deciding on my motherboard and RAM.

I found this thread in toms hardware:
http://www.tomshardware.com/answers/id-3353224/choosing-x370.html

I have a few questions:
1. Is The x370 motherboard the current best for the Ryzen?
2. Are their any X370s that have 16x/16x PCI-e slots? ( I can't find any )
3. What would be some very fast RAM (16GB Sticks?)

Budget:
Motherboard: $250-300
RAM: $400-450

Any help would be amazing, it's been 7 years since I upgraded.

AwesomeB,

The AM4 motherboards vary according to overclocking and the presence of 2X PCIe...
It's early so there's plenty of things to shake out yet.

Couple of things I would say is that from a few of the reviews we've seen so far, Ryzen does seem to perform better with fast RAM. But also, because everything's new, RAM compatibility can be a bit temperamental. SO, it's absolutely worth RAM shopping from the QVL (qualified vendor list) for motherboards if you can. If you decide to go with the Asus board @WiiU suggests above, here's the RAM list I'd be shopping from: http://dlcdnet.asus.com/pub/ASUS/mb/SocketAM4/CROSSHAIR-VI-HERO/CROSSHAIR-VI-HERO_DRAM_QVL_forAMDRyzenProcessors.pdf?_ga=1.76020437.139019751.1464317467
I don't think you need anything like $400 for your RAM budget. Even if you want 32GB of high speed RAM (which is probably overkill). But choose your motherboard, then find the QVL list (or whatever the brand you choose calls their RAM compatibility list), and shop for RAM based on that.

Also, bear in mind that if you're prepared to overclock, there is basically no difference between the $500 1800X and the $330 1700 (non X).

Boards with two x16 slots will require PLX switches. I've no doubt we'll see those in future, but mobo manufacturers apparently only got a few weeks to validate their boards with shipping CPUs, so that's why there are basically no custom/exotic boards out yet, like mITX boards or high end boards with PLX switches. Test after test that I've seen shows that x8 PCIe 3.0 lanes is plenty for high end gaming. Plus, those PLX chips add a little latency which seems to take a couple of FPS off anyway. I wouldn't wait if I were you.

AwesomeB,

The AM4 motherboards vary according to overclocking and the presence of 2X PCIe x16. If you're using two GPU's, that will make the choice X370.

The problem is though, the Ryzen 7's support a maximum of 20 PCIe lanes and it won't be possible to run two GPU's at x16 plus an M.2 at x4, and so on. Still, many users have SLI configurations on i7-7700K systems and that CPU supports only 16 lanes. There is some lane sharing and tests show a GPU running at x8 still works well.

I was interested in Ryzen 7 for workstation use, thinking I might replace a 6-core 3D CAD and 16-core rendering system with a single 8-core 1800X. This was based on the pre-release reports of the 1800X potentially having the same single-thread rate as the i7-7700K is overclocked to the same 4.5GHz which is a Passmark score of 2597. However, the 6-core I use has a Passmark single thread rating of 2077 and every time I check, the Ryzen 7 1800X score has dropped as more samples are added. Two days ago it was 2021 and today it's currently rated at 1997. For comparison, the i7-6700K is currently at 2351.

The Ryzen 7 number is based on only 45 samples, but the trend should be towards a rising score as users work out how to get the best out of the CPU. When they are sorted out, they do work well. The top CPU score for the 1800X is 18901, making that single-thread rate of 2362- the same as an i7-6700K, and that's using a Gigabyte AX370-Gaming 5 motherboard )$300). the second place MB is the AASUS Prime X370-PRO: CPU score of 16876 which = single thread of 2109.

The highest 3D score for a 980Ti- probably two- is 13418 using an ASUS X370-Pro - $170 and that looks like a good value.

I notice that the RAM scores for 1800X systems are not outstanding. I've seen mention that if as the slots are filled, the speed it supports drops. On one report: if two slots are filled it will run 2666, but if all four are filled, it's at 2133- that kind of thing. Look at the MB makers' recommendations for RAM before buying either the board or the memory. I'd say, the memory is something to really look into carefully. It's early days with a new technology.

Cheers,
