AMD RYZEN Builders Thread

it's a fairly simple process that a number of us would be able to help you with, so I wouldn't stress over it too much.

the board may not run the correct values automatically, thus it's very helpful to know your way around the system BIOS (it's actually much easier to navigate than it used to be).
 
I finally got around to building my new Ryzen system with the stuff I got at Microcenter on BF. So, Gigabyte AB350 Gaming 3, Ryzen 7 1700X, Corsair water cooling, Corsair vengeance 3000 w/LED's, 512MB SSD with Windows 7 on it from my previous system( Phenom II X6), 4TB of storage drives, Antec 620W PS, and my old HD 6850 vid card while I wait for a decent sale for the RX 580 I want to get. Installed the latest chipset drivers, updated the bios, set the memory for 2933, left the processor speed stock... The system runs really well and the SSD swap to the new system saved me a day of reinstalling stuff. Only problem was the USB drivers, and I had to plug in a old PS2 keyboard to do the chipset drivers that I had already saved to the SSD.
So far, so good except for the constant nagging by MS about an unsupported processor on Win7. Any way to turn that notice off? It actually did an update last night, so I know it will do some updates. (I need to keep Win7 on this system for Media Center and my TV tuner).

Also, is it possible to make the LEDs on the memory either stay on or turn it off since the constant fading in and out is annoying? Any other tweaks I should do?
 
ASRock AB350M Pro4 boards have a couple of new BIOS releases. 3.30, and 4.10. Note that the notes for 4.10, say that you NEED to flash 3.30 FIRST. Which is interesting, because "Instant Flash" wouldn't even pick up on the 4.10 BIOS on a flash drive, with the 3.00 BIOS, only the 3.30, and then once flashed to 3.30, it would "see" the 4.10 to flash. Always reset to UEFI defaults, before, and after, flashing. At least I did, to be "safe".

Doesn't seem to help overclocking any, and didn't help with my Team DDR4-3000 memory compatibility. (If I set XMP, it defaults to 2933, but then refuses to POST, and just beeps three times, then power-cycles. This continues around three times, then it comes up, with the RAM defaulted to 2133 again.) Highest I can get it to reliably POST at is 2667.
 
Hi, all

have been trying out 3008 bios on C6H.

Well it does run really well, yet I cannot get stable 3467MHz DDR4 CL16,16,16,39. ( error at 1600HCI%)

I did some AIDA64 benchmarks and got carried away. Started to calculating impact of DDR4 true latency, core latency and IF latency.
Here it goes:
My calculations are not that accurate (~5ns+-) and probably not correct, but based on AIDA 64 I got these numbers.

IF latency impact at (AIDA64):
1067 MHz = ~ 78,8 ns
1466 MHz = ~ 57,3 ns
1600 MHz = ~ 52,5 ns
1800 MHz = ~ 46,7ns (I haven't reached 3600MHz DDR4 at decent CAS and stable since I have problems with 3473MHz for 24/7)

If my calculations are true then : 3,8GHz + 3600MHz CL16 DDR4 you should be around ~ 67,2ns. (Yet again CAS timings are important)

Just for fun :
2000 MHz = ~ 42 ns
3000 MHz = ~ 28 ns

If future ryzen generations will allow to clock IF separately (first gen is bound on IMC) and if possible of reaching 3Ghz, DDR4

PS: Did something scary, I have to 1.2V for DRAM and 1.4V for VSOC and then went for memtest. Suddenly (10 sec of running) I see VSOC power around 33W and I was like WTF and the voltage 1.36V... insane. 😱 Made my reflect of the year - searching for "shut down" button.

I tried 1usmus ryzen DRAM calculator for Samsung E die and cannot even boot with his settings (fast present).

Hynix settings does boot yet not stable @ 10000HCI% sometimes even worse latency and speeds.

Also with this Samsung E die I have hard time on 1.45V.

New settings, I did some of my own customization, but also Ryzen DRAM calculator helped a lot.
BIG Thanks to you @TheStilt and @1Usmus from OC.net

My aida64 bench.

So Fast preset from @1Usmus just doesn't work not even on lower speeds, so what I did actually here was using 2933MHz in calculator and run it on 3333MHz.

So if anyone with E die will have same problems as I had, go with hynix XMP profile (fast preset) or E die safe preset. I did you alternative and also tRFC (283T/174T/120T).

Well with XMP C6H had some problems.

- Why runs unstable at stock clocks XMPs?
Well it won't change some settings and it will run it on Jedec standard for CL15. It will only do XMP CAS latency, but other timings will stay at Jedec standard.
XMP tRFC is 451T , jedec is 312T, and so on... That was the biggest issue.

- Timings?
Even with my timings set to 13-15-15-15-32, C6H will run 14-15-15-15-32 with and so on,... So after restart I went back to BIOS and correct those settings as C6H-DRAM had put it on its own.


My conclusion:
3dGuru and techspot and many other reviews are talking about cross CCX latency (IF), that doesn't matter. IF is hard linked to IMC offering DDR (as DRAM) and most important for high FPS are IPC, IMC and DRAM latency. No, CCX latency doesn't matter here since windows is aware of RYZEN topology. Yes, you can get 1-3% delta. From my own testing I got like 3fps difference at 150fps, maybe just an error (CPU bottleneck).

1. So I have noticed that most of reviewers didn't do that. Since AM4 have problems with timings on XMP they didn't fix it.
http://www.guru3d.com/articles_pages/amd_ryzen_7_agesa_1006_performance_update_review,9.html
You can check latency and speeds of different stick and you will notice the same problem as i did. Sometimes even with same CAS timings you can see way lower speeds and up to 5ns of higher delay.

2. XMP problems?
Some people still cannot achieve those XMP timings and that is probably the cause of it. If, you cannot touch timings as I can on C6H contact your manufacturer and tell them that you have problems with XMP profile. Hopefully they will help you. Like I said I think the problem is that some timings with stay on JEDEC standard.

3. What timings to improve?
All Timings/subtimings are very important for Ryzen.

It's important to remember that XMP is officially an Intel thing anyway. These DIMMs need AMP profiles, which they may get someday if AM4 remains a popular option for DiY buyers.
 
Thanks for all the memory-tuning info guys!

Yesterday I managed to get my corsair-3200Mhz-c16 kit working at the fast preset, suggested by the calculator:

Eb4lzHE.png


Its running with CL14 (14-14-14-28) with those exact numbers @1.37V (1.36 actual).
The problem? It was actually running well with the official XMP latencies (CL16 16-18-18-36) @ 3466 Mhz with the same 0.1v over stock voltage (stable over multiple memtest86+ runs and actual usage for a few weeks).

I'm not near my desktop right now, so I don't have the bench results nor the Ryzen Calculator stats for 3466, but the bottom line:
@ 3200 even with those more aggressive timings, my AIDA64 mem-latency is barely better than before (about ~75ns. Managed to get 71ns once, with all other software disabled except Windows Defender). The bandwidth is also marginally worse (obviously).

Now, if I insert 3466 into the calculator, it gives me crazy-high voltages even with "Safe" preset. Is it really ok to run RAM, rated for 1.35v, with 1.4+ volts?

TL;DR:
Should i run my aforementioned B-Die memory kit:

1. @ 3200 Mhz with CL14 (14-14-14-28), 1.36V as per the calculator
2. @ 3466 Mhz CL16 (16-18-18-36), 1.36V with stock timings (that seems to give better bandwidth and same latency in AIDA64)
3. @ 3466 Mhz with calculator settings (if I remember correctly, "Safe" was 15-13-13 ...) with stupid voltages above 1.4V
4. Something else?

I use 1.42v vDIMM on a regular basis on my b-die kit. Most b-die should be good for up to 1.45v before you're in the danger zone.

Either way I would go with a 3466 setting since that also ups your IF speed.
 
the 16GB dual channel kit I bought for $170 back in March or so is now $235... no more Ryzen builds until that madness levels out.

this has been the worst holiday season to build a new machine in quite some time, between memory and GPU price gouging... terrible market.

Samsung is ramping up 3200MTs+ dram
 
Much as I wanted a new Ryzen system , the ram prices put it out of reach. Even settling for a $50 video card ... 🙁

I just looked at a random Corsair DDR4 3000 kit... it was a little bit over $160 at launch. It's now $205. And people were complaining about the prices at launch compared to where DDR3 was. The low was $70 btw.
 
y-cruncher uses "ADX" which basically pushes your Ryzen harder than anything else. But you can try the latest iteration of Prime95 for AVX/AVX2.
 
Would anyone be willing to chime in and share which B350 motherboard with PCI slots is the one to get currently, as well as the best value X370? I might get a 1700 and that would be a "budget" build either with the best B350 or best value X370. If it's neither of those it'll be Threadripper.
 
If TR is in your budget, seriously just get that. Or hold out for Pinnacle Ridge.

Otherwise, here is a list of AM4 B350/X370 boards with at least one PCI slot:

https://pcpartpicker.com/products/motherboard/#s=33&c=124,123&d=1,6&sort=price&page=1

Of those, the only B350 board I'm reasonably certain has the correct VRM configuration for a 1700 is the B350 Tomahawk. Not 100% sure about that Biostar B350 board. All the X370 boards there should be okay for a 1700.
 
Quick question:

- I just got the Ryzen 7 1700 with an ASUS motherboard (Prime x370-a); what software/utilities if any do you recommend I install to monitor/manage/overclock this system?

I don't intend to go nuts overclocking, only use it when needed. Other than that I want to monitor the system to see that my USB 3.1 gen 2 port is working at rated performance, check fan speeds, temperatures etc.

Any advice appreciated.

🙂

Honestly, if you are new to building a system and overclocking in general -- do yourself a favor and either do extensive research on it so you can overclock the right way via Bios. Make sure you have adequate cooling, etc as well, and correct parts (ie RAM).
As for monitoring temps go, I trust Core Temp more than some of the other softwares. It's super lightweight.

Can't really recommend software, since I only use Corsair Link for my CPU cooler and Core Temp, and CPU-Z. That's pretty much it.
 
1. Prime x370-A has pretty weak VRM, I think it is the weakest X370 board. Heatsink is also garbage.

Well I would overclock, if you have good case ventilation (to cool down VRMs). You can expect 3,6GHz maybe 3,8GHz for 24/7 and be careful with VRM temps.

2. As you can see that board has capacitors pretty near VRM and VRM can heat up to 120-125C while working, capacitors aren't that good with high temps.

If you have good ventilation then you can hope for good OC, otherwise anything above 3,5-3,6GHz for 24/7 is quite risky unless you are ready to replace board in a ~year.

EDIT:
FOLLOW GUIDES
Have fun, use HWinfo, be careful with POWER readings/VRM TEMP etc.
- I would go with simple OC like 3,5GHz
http://www.overclockers.com/amd-ryzen-overclocking-guide/
- Memory OC
http://www.overclock.net/t/1640919/ryzen-dram-calculator-overclocking-dram
Do not do anything stupid, take it slow.

Hopefully you have good silicon there. I have heard that some can hit 3,8GHz - prime95 stable (small FFT) at 1.25V on load.

PS: Even at stock clock, you will be surprised by ryzen speed with decent memory (speed,timings/subtimings)

Again, HAVE a LOT of FUN!
