You can probably get by with a cheap fan controller like that. Most of them are just cheap potentiometers anyways. This is the one I use, but is likely overkill for most users. 30W per channel x6 channels. I like running lots of low RPM fans:

I don't know what your personal noise tolerance level is, but I think most of us with what can charitably be called "old ears" would be fine at <1500 rpms. I think full speed at 2150 rpm would be pretty noisy, however. I might not really notice given my hearing damage and tinnitus, though. ;)

Do you have an idea of how your Cooler Master is performing?

I'm running mine at 3.8ghz *stable (with the stock cooler) for almost a week now doing lots of tasks.
I ran Prime95 for about 40 minutes to verify my RAM at 2933 was stable (as stable as 40 minutes would tell), and I saw temps in the mid 80's. The temp seemed to bounce between 70 and 86 based on where it was in the Prime95 test.
When not doing Prime95, but everything else I'm in the 58-65 range.

*stable = I've had the machine on the last three days non-stop exporting over 100,000 photos from my Lightroom catalog. LR seems to continuously have a modest load on all cores. The nice thing about the chip is I'm able to play Dirt Rally or Overwatch while the machine is doing this without much ill effect.

Highest it's been is at 75C after 4 hours of prime 95. It's performing remarkably well. I used Arctic ceramique thermal compound for mounting.

Well after some more tinkering and tweaking I arrived at 4.1Ghz with 1.41v. I bumped up the CPU SOC voltage to 1.225v and then the DRAM voltage to 1.3875v and was able to get a stable 4.1Ghz overclock on my Ryzen 1700. I still can't get my memory to run at it's rated 3200Mhz 16-16-16-36 even by bumping DRAM voltage to 1.45 and slackening the timings to 18-18-18-42. I'm stuck at 2933Mhz 16-16-16-38 at 1.35v. I hope they get that new BIOS out soon that will allow higher memory speeds. I'm currently on BIOS F5D for my Gigabyte X370.

Temps climbed to 79C under load after a few hours of stress testing. I don't think I'm going to keep this OC as temps are getting higher than I like. Maybe if I decide to water cool I'll bump it back up to this setting.

Many sites mentioned that SoC voltages should not go above 1.2.

I've heard one of the reasons the C6H bricks is excessive SoC voltage. 1.2v has killed a few boards apparently. Not sure if it's the culprit killing the Gigabyte boards that're going down. Personally I haven't pushed past 1.05v

MB - Asus Prime X370-Pro
CPU-1700X
Patriot Viper 32 GB 2400 Mhz (16 GB x 2) set at same speed & at 1.35V

3.9 Ghz at 1.40V.

On a side note, I set at 4 Ghz at same voltage & tried a conversion with Handbrake & it immediately rebooted. Tried lowering to 3.95 Ghz & it rebooted after a few minutes.

Looks like I got a golden 1700 @ 4GHz:
Ryzen%20B350%204000MHz%201700_zpsfftsuwry.png


Can go lower than 1.38V in BIOS (still dialing it in). Alternatively, once I get my hands on a solid X370 overclocking board that lets me go over 1.40V on vcore I could probably at least bench at 4.1GHz. This mATX mobo has a BIOS limit of 1.40V vcore (probably so the VRMs don't blow up). I could boot at 4.05GHz into Windows at 1.39V but it was not stable.

Welcome to the club IEC :) Try getting that memory speed a little higher, you should be able to get 2666Mhz at the very least. Also download Ryzen Master you can use it to tweak settings further and adjust memory speeds and timings.

Just changed my vote. Now running solid at 4 Ghz on my 1800x with ram running at 2400. Ran RealBench an hour and past. Max temp on core was 80C but average was 71C as measured by AIDA64.

I'm running a custom water cooled rig with an EK EVO AM4 cpu block and 2 360mm slim rads.

Well, spent the last day tweaking, and my 1800x@3950 that I rated at a rounded up 4 ghz, simply refuses to do actual 4000 stable even at over 1.41 vcore. I am not going higher.

But 3950 it will do @ 1.3875

Interesting. My 1800x seems to crap out at 4075 MHz. I can get 4100 MHz running, but I have yet to complete a benchmark at that speed without the entire system shutting down, requiring all kinds of UEFI meddling to fix settings etc.

Per chew* on OCN who added solder leads to vcore and vsoc to measure voltage via hardware (DMM), some boards are not reporting voltages correctly. So I would take "1.4V" with a grain of salt as it may actually only be giving 1.3X vcore instead.

Give it a little time for the more adventurous users to figure out which boards droop and BIOS fixes to roll out before attempting extreme OCs (1.4V+ and LLC >= 3) imo.

Still tweaking, but currently running
Ryzen 1800x @ 3.9 GHz 1.28v
Asus C6H
Crucial Ballistix 2400MHz
4 GHz did not run at 1.35v.
So i try to stay at 3.9 and undervolt till there is no tomorrow.
When RAM issues are settled i will move to a kit that will give me 3200+

Give it a go @ 1.385v this worked for my 1700 @ 4.00GHz, could probably run higher as temps don't generally raise above 60c after several hour stress testing
Ram is @ 2666Mhz with 1.355v (+1) and DOCP selected. Should run at 3000Mhz but i'm happy at the moment as timings are CAS 15-15-15-35 Timings

I was able to get 4050 MHz, but I had to go to CPU Voltage at 1.4V and I was not willing to go there.
Good lord, 1.55v? Are you trying to kill your CPU and motherboard? Pretty sure AMD said not to go over 1.4v at this point in time. Thats scary stuff for sure and you must have some good cooling for that kind of heat out put. Yikes!!

The voltage is 1.375

3.4Ghz @ 1.25v lol...

new BIOS is out so I'm going to see how close to 4ghz I can get

Are you sure cause both apps are showing 1.55v and you cant always rely on bios to tell you the correct voltages as the bios are all buggy and pretty much in beta form contrary to what the manufacturers are telling everyone.

BIOS is usually more accurate than the programs in Windows

right now 3.7ghz with 1.34v... haven't really dialed it in yet. onward to 4 tomorrow!

just kidding... 4.0 without much fuss... temps up by 10c though

If you check the OCN link above, the only way to be sure you have an accurate voltage is to add solder leads behind the motherboard and use a DMM. I wish the C6H hadn't bricked because it had lead points on-board, but maybe I'll do this to a Taichi if I can get my hands on one...

I am 99.9% sure the software-reported 1.55V is incorrect and it's closer to 1.4V actual.

1700X at 3.8ghz at 1.375v

16 Gb Corsair Dominator 2x8 3000 C15 @ 2400 C16

Tried 3.9 at this voltage but it locked up in about 15 minutes under 100% load. seems perfectly happy at 3.8 however. Haven't had an opportunity to try 3.9 at 1.4v. Will post back when I have time to give that a run.
