    looks really good, what are your load temps looking like?

    Na, that won't hurt that CPU, however you might want to set a Restore Point for your OS. AMD lockups, can bork your OS. It is not a common thing, but it can still happen. Intel lockups can too, but those seem less common to me than AMD's.

    What is CPUz reporting your vCore at under load? And is there a vCore listing in HWInfo? See if those match up. And congrats for getting it back to where you want it. :)

    With ambient temp. of 62F in the room, the max. CPU temp. hit 68C. With the ambient temp in the room more realistic and more comfortable (70F), the CPU temp will max 71-72C. CPU throttling happens with temps. above 68C which is counter intuitive because stock settings will encode video faster than a throttled overclocked CPU.

    That is all good and a badass overclock on a 1950X at that vCore. You done good!

    Here are some pics. Not the sexiest thing around but it works for me. By the way, installed the Noctua NF-A14 IndustrialPPC-3000 on the front of the Silver Arrow and it shaved 5C off the temps! Maybe I'll try to push 4.1 Ghz OC.

    looks fine to me. idk how I missed that youre using the silver arrow, I thought you were using the nh-u14, missed it in the op. that's why I thought you were have issues due to the hsf, oops. glad you got it sorted!

    Right now for almost two hours, CPU all cores 100%, have a stable OC at 4.025Mhz and good temps.

    This thread is relevant to me: Running a 1950x on MSI Pro Carbon OC'd at 4.0, 1.268v, 66*C in Prime95 on Enermax AIO. Rock stable - but maybe I should be trying to squeeze it down to another few .00x volts? Seems not many people around push too far past 4.0ghz. What's the wisdom?

    All depends on how high temps you are comfortable with. Personally, I do want to keep the 1950X under 68C. Other people say not to worry if it reaches 72C. How much do you want to squeeze out of an already ripping processor at clock speeds and at what cost?

    I'm under 68C. Just curious what the headroom is on these - or at least what the conventional wisdom is. Lots of 4.0 OC's, not many beyond. I guess it's the point of diminishing returns.

    AMD does not recommend above 68C and temps above that will cause throttling. I mainly do video encoding with Handbrake/Vidcoder with very high quality settings which taxes the hell out of the processor. From the stock 3.4gHZ to 3.999 is a noticable difference in performance. From that point to 4.0 or even 4.1 is splitting hairs with maybe shaving off a couple to a few minutes at the most. I admit it can be an obsessive quest to squeeze the highest frequency out of the processor but at the end of the day, encoding a 1080P superior quality full movie which only takes between 1 and 1 1/2 hours compared to 4 hours with my old Intel i7 4770K is a huge performance difference. With 5+ movies in the cue, that's at least a 10 hour savings in time.

    Yeah...I get it. Just maximizing the clocks without doing unnecessary damage. As I recall, you were reaching for 4.05ghz - on a very low voltage.

    Testing Stability is misleading in my opinion. I have a 4.025ghz at 1.28750 Volts. I don't believe in torture testing a processor with Prime because it puts a tremendous strain on the processor so my torture test was to run 4 instances of Handbrake simultaneously encoding videos for several hours. This was stable and temps reached 67C as a max. Everything completed successfully with no issues. When I encode video, I only run one instance of Handbrake and if I have multiple videos to encode, I put them in the cue. After encoding videos for a few hours, I found my PC locked up which means it isn't completely stable with this voltage. I increased the voltage to 1.3V and that seems to be stable however temps were reaching 71C. I am going to back it down to 4ghz which in reality will be running at 3.999ghz at 1.28750 volts. Unlike Intel, Threadripper is very difficult to overclock because of the heat. From what I have read, the only way to push the processor past 4ghz is to have custom water cooling which I am not going to do. People have reported being able to get 4.1ghz out of the 1950X with custom water cooling with low temps. The AIO water coolers including the Enermax don't seem to perform better than the Thermalright air cooler. When I built my PC, I started with the Enermax Liqtech TR4 360. I had to RMA this cooler twice because of problems with leaking and pump failures. Apparently, most people using the Enermax cooler have reported similar issues.

    I see. I think it's acceptable to round to 4.0ghz for purposes of discussion. I haven't had a failure with that exact Enermax ...yet. If it does start to exhibit a problem, I will do a custom loop.

    I suppose I'm at the sweet spot in terms volts/heat/clock. 1.268v/66C/4.0 I'm very comfortable; guess i should stay there and be happy.

    What do you use your system for primarily?

    Watching the two functioning RGB fans spin. YouTube it up. Occasional adventure into Prime/Netflix.

    Oh. Just got BF5, so playing that a bit.

    However, in seriousness, my plan is to use it as a lab to play with VM's.

    Thank you dpriest, just like Kyle and the [H]orde solved your use case, newbies to TR4 platform like me can take valuable pointers from your build. I am just as wary of AIOs as yourself but it comes at cost of additional build considerations viz. RAM profile, PCIE clearance and cabinet to account for these requirements. So could you please include your build details.

    From your pics, I could see below items:

    1)CPU - Threadripper 1950x 4.025@1.28V, Silver Arrow TR4
    2) Mobo - Asrock Taichi x399
    3) RAM -
    3) Cabinet - Phanteks



    With silver arrow TR4, how easy it would be for you to expand to all 8 DIMM slots in future.

    I have to say that I did it right. The Phanteks Enthoo Pro is an awesome case and it is very roomy. To answer your question, I can expand to all 8 DIMM slots if I want to. My graphics card is in the 1st PCIE slot and there are no issues of clearance and plenty of air flow. Here are the details of my build:

    1.) CPU - Threadripper 1950x 3.9@1.262V, Silver Arrow TR4
    2.) Mobo - Asrock Taichi x399
    3.) RAM - Corsair Vengenace RGB 4x8GB DDR4-3200
    4.) PSU - Corsair Enthusiast 750W 80+ Bronze Semi Modular ATX Power Supply
    5.) Fans - 7x Noctua NF-A14 Industrial iPPC-3000 PWM Fans
    6.) Video Card - Gigabyte - GeForce GTX 1050 2GB OC
    7.) Hard Drives - Samsung 970 Pro 512GB, Samsung 960 EVO 500GB, Seagate Barracuda 1TB 7200
    8.) Fan Controllers - 2x Thermaltake Commander F6 RGB 6 Channel 5.25" Bay
    9.) Optical Drive - LG - WH16NS40 Blu-Ray Writer
