Planning new build! Ryzen!

My current specs:
- Intel Q6600 core 2 cuad (no hyperthreading).
- 4GB DDR2 ram.
- Motherboard: gigabyte whatever, 1 PCIE 1.0 slot and a bunch of PCI ones.
- SATA 1 and 2 drives (upgrated to SSD's, but running at less of their speeds because the machine is SATA2)
- GTX 550ti (1080p monitor and 1600x1200 monitor).

Usage you will be surprise what I can get out of this machine with 4 GB of ram + 16 GB swap partition.
- Elementary OS Linux
- Intelij IDE
- virtual box vm with docker
- Mysql, Mongo, Docker
- chrome with 20+ tabs.
- terminals, build runs, deployments..etc
- should I keep going? :P
- live recording of the desktop using simple screen recorder app for linux.

It caught fire the other day!, the DVDR power cable shorted somehow! I had to cut it to keep it running!

Target Build:
- Ryzen 1800x (yes I know folks have been overclocking 1700 with good results, but for 170 dlls I wont risk it, I will just get the better silicone).
- 32 gigs of ram (2x16 GB sticks)
- Motherboard: IDK, so far ASUS seems to be the worst brand, and Asrock and gigabyte the best for Ryzen.
- some MVME samsung drive, perhaps 512 GB.
- 2 displays 1440p IPS 27 inch would be great to keep 100% DPI on Linux since 4K at 27 inch would give me 200% DPI and it would look to big.
- RX 480 video card (seems to be better supported on Linux than Nvidia variants, nvidia is not playing nice with Wayland). I don't game, last game I played was Witcher 1, and some WOW with some coworkers a few years back.
- Some very high watt power supply for silent operation.

Question for you guys:
- Ryzen builders:,
1. can you comment on motherboard brand experiences? better bioses so far and support from the vendors.
2. Ram brands to get 3200 Mhz
3. Anyone tried two 16 GB sticks to see if speed gets affected?
4. Water or Air for better silent experience. I will be probably not overclocking the 1800x since it appears it does not overclocks well (like 100 mhz the most).
5. Any builders experience on noise levels on their builds?

Suggestions welcomed.

Nice build you're aiming for and since you're not gaming, waiting for Vega and/or RX 580 wouldn't make sense either.

In terms of getting a 1800X instead of a 1700: I think a 1800X increases your chances in the silicon lottery, because it guarentees a certain performnace. If you're lucky a 1700 will run as good as a 1800X, but i doesn't have to. Depending on your financial situation a 1800X might be a sensible choice.

NVMe Samsung drive - that mirrors a thread of mine :-D (although I propably won't end up purchasing it)

PSU: What du you mean by very high? Is 850W very high - Ray used in his build a 850W PSU and had a 1800X and two Titans in it, thus it should be fine for you as well.

Mainboard (another thread mirror it seems :D): Well since they are new, there isn't much to recommend. Taichi seems to work really well, ASUS (as you've mentioned) doesn't.

Noise level: I guess you need a new PC case as well. I pruchased the F51 a while ago but I don't know if it's any good. I also got this CPU cooler when it was on discount, but again, I don't know how noisy it really is.

Just FYI, any ryzen chip will run like ass on elementary. The kernel is too old.

Disable smt, install, boot compile 3.10.x, enable smt. 😁

Why disable smt on Linux then add it back later?

I think you mean 4.10?

SMT doesn't work quite right on older kernels.

gskill recently validated one kit on 3200, another on 3466. theyre completely new branding and use top end samsung chips

you'll pretty much have to do bclock OC to get it that high stable with reaspnable timings though, meaning you need a board with external clock gen (the GB and asus top end boards have them, but not every x370 does.

I read that the highest the wattage, lets say 1200 watt, the more wattage it can deliver before turning the fans on the PSU on.

Yup!!

From what I read, unless you have 4.10.X you get random crashes with SMT enabled, but I guess it can be disabled to get bootstraped and then get a newer, or build a newer kernel.

Nice, I will try to find out the model of the ram. I saw a review where they showed performance increese by a lot going from 1800 mhz to 3200 mhz, but the delta between 3000 mhz and 3200 mhz was not really noticeable. Although these were games, I don't know how it will impact the overall performance of the system. and which is the speed threshold of diminished returns. Probably around 3000 Mhz. But lots of the folks on review they could not get their ram to work over 2100 mhz.

The other thing is that I would completely rework your computer build.

I would drop down to the 1700, and get an Nvidia GTX 1070. Then instead of getting two 1440p monitors, I would just get a 34 inch 1440p wide screen monitor.

Its a much nicer and more stream line setup.

I would not even think about the 1800x. My friend returned his because we both got the same overclock and he spent 800 bucks on his cpu and an asus crosshair and I spent 400 on my 1700 on asus B350 prime.

I also know that nvidia and wayland are in fact working. Right now it is still in beta, but when gnome 3.24 comes out we should see nvidia and wayland working together out of the box.

I like to watch series fullscreen or concerts sometimes while working, and a unltra wide would only give me 1.5 wide factor of a standard 16:9. Or maybe the ultra wide and a smaller 23 inch 1080p, but then is toooooo wide!! :)

I have seen a lot of reviews of folks OC the 1700 to 3.9, but not that many to 4.1, and I have also seen some that can't get a 1700 stable above 3.7... Again is hit and miss, and since this is my workstation, well I rather pay the extra 170 dlls to be sure of the better silicone.

I would consider looking at the specs of the B350 and if they are sufficient maybe I can get one of those instead of the 370. But from what I can tell the ASUS brand been sucking.

What is wrong with the RX 480? why don't you recommend it? are the drivers bad?

They couldn't get high stable OCs, either because they tested without Ext. clockgen, or because they expected XMP to "just work" without subtiming control.

the G.Skill series' are called FORTIS and FlareX, respectively.

I have no idea what ext clockgen is :P

normally, a chip generates its own Baseclock (the frequency that the multiplier is applied to.) An external clock generator is a component on the motherboard that lets you bypass that base frequency

On ryzen, because you don't have access to XMP sub-timings, the only way to run memory above 2600ish stable with good performance is to do bclock overclocking, which raises the frequency of everything that directly communicates with the SOC including the RAM

Ryzen needs a Mobo with an external clock generator to do this effectively, meaning you need one to get good memory OCs as well

for example, running bclock at 114 instead of 100, a multiplier of 35, with a 2666 preset on the ram would get you around 3.9 Ghz on the core, with memory around 3033 and reasonably tight timings, meaning it will be much faster and (at the moment) more stable than doing a multiplier OC and using the default 3000 profile because it bypasses the memory controllers regular limitations

so to get good, consistent Memory OCs, you'd have to do something like

Bclock    Multiplier    Ram Profile    CPU/RAM Result
113       34            2666           3.84Ghz/3013
120       32            2666           3.84Ghz/3200
118       33            2933           3.89Ghz/3460

ryzens been having toruble with ram past 3000 atm and sometimes even ram past 2800. might want to wait a week or two and keep a ear out for the fix.

also a 480 is fine for 1440p unless you want really really high frame rates in games which you dont play much. you'll even be fine with 144hz if you have freesynch.

also currently you can not do gpu passthrough with ryzen do some bugs which are being worked on.

also use air cooling if you arent going to oc and want silence. check out noctua's stuff, or just get a cooler that lets you switch the 120/140mm fan and replace it with a noctua. if you water cool, the pump will make noise even if the fans are silent, and you cant turn it down too much or the thermals skyrocket.

and what case you using? use something with good dust filters + noctua fans on silent mode with rubber mounts and you should almost never hear the machine.

compare the clock speed vs. multiplier on these validation screenshots. note the base profile is 2133 here, so even more extreme than I suggested:


Even that seems to be buggy I saw a video from youtube that after sleep/wakeup the clock runs slower, and it gives better benchmark resutls. until a reboot... I guess that is dual clock sync bug. because cristals just don't change speed, its not how they work.

So do you think this V1 Ryzen architecture is going to stabilize? or the memory controller on Ryzen is just broken?

on AMA Lisa said that one of the thinks that could be improved was the memory controller, something along those lines, but it was not clear if this was software or hardware improvements...

So for 170 dlls price difference between 1700 and 1800x, it might be cheaper to pay 170 extra dlls than deal with the time to learn and stabilize the build.
