In googling around on uninstalling Aura, I found a program called "Advanced Uninstaller PRO 12". I installed it, ran an uninstall of Aura 1.04.26 and a registry clean with the program. It did seem to find more files and references to fix. I then ran an install of Aura 1.04.29. It went a bit wonky and brought up the damn Doctor Dump thing, but then did install. I was not optimistic, but tried a startup of Aura and what do you know, it opened, showed the G.Skill RGB! I ran the calibration thing, and tried out some effects and now it all seems to work. I rebooted and opened it again, and still works. Some may be solved!"

Since that post have not had any further problems, so I declare it working for me.

Thanks, will give that a try.

I found Battlefield 1 better than F@H for system stress test. More fun too biggrin.gif

So i need a little help from people who are having boot loop issues with ram.

Ive got my ram to work at 3200mhz, dram at 1.36 dramboot at 1.45v and soc at 1.15 (that seems to be the key). After i shut down it boots and instantly its a code 15, pressing the reset button on the case and it boots right up no issues.

How can i make it so it boots right the first time without resetting, do i need to up soc a bit more or dramboot voltage?

Most people really REALLY overestimate watercooling when it comes to a cpu.

Example, my 1700x at 1.199v under load reaches around 50°C tctl and my gpu at 40°C, running a 360 (push/pull with 6 fans) and a 240mm in push. Adding more fans will increase the dissipation but not by a crazy amount, running fans at a faster speed will, and so will running the pump a bit faster (depending on what cpu block you're using)

Compare your temps to people hitting 70-80°C on air with the same voltages and water does FAR better then air if you have the loop for it. It is after all an 8c/16t cpu.

I agree entirely.


The loop I am putting together for this build is pretty modest. I am running dual slim 360 in push pull with some 3k EK fans. They are good radiators with a 30 FPI, but they are also very restrictive.. Seriously.. they are VERY restrictive. So.. because I am running dual GPU blocks, and a CPU block (EK FC / EK Evo), and two very restrictive radiators, I am going to run the loop with a dual pump unit to up the head pressure. I am aiming for 1-1.5 GPM.... two would be nice... but not expected.

I have a bunch of TG Konductonaut liquid metal tim on hand, so I will use it for the TIM.

Hopefully that will be enough to run 4.0 @ ddr4 3600 without throttling.

All my failed cold boot issues have been solved by increasing SOC voltage. But I am guessing it depends on the CPU's IMC. Mine boots at 3200 fine at .96875 though, which I was forced to increase from .95.

For the most part radiators aren't very restrictive, they pretty much just flow right thru it's not an issue. The most restrictive in my loop is my alphacool gpu block, even a cpu block is more restrictive then a radiator, unless the ek ones are very restrictive one pump shouldnt be an issue. The problem youll run into is 2 360s (hopefully with high static pressure fans for that 30fpi) isn't going to net you very good temps. My 360 and 240 is barely enough for my 1700x and r9 390 for me to get awesome temps. If i ran dual gpus and an 8 core id be looking at dual 480s lol.

Ah damn. I tried 1.0 and that does just fine at 2933 (havent tried any lower though so im sure it could) at 1.1 it would boot but give me a 15 and then 0d, 1.15v gives me a code 15 right away and pressing reset boots it right up, at 1.1v even pressing the reset button it would not post just boot loop 14-15 and then finish on 0d. Id really hate to give it more soc but might be that my cpu has a great oc capability but more imc.

Read the link... These radiators are more restrictive than most CPU blocks.

That said... these slim line rads perform better than almost all 40mm rads, and even a large number of 60mm rads. It is all about the disipation. That high restriction is there for a reason.. thumb.gif

Good. thumb.gif
What voltage (and I mean DRAM Voltage and DRAM BOOT Voltage) do you apply to RAM DIMMs to get them work at those timings?
What voltage to SoC?

Thanks.

Not at all, and I agree with you. It is a benchmark, not a stress test.

For stress testing I use Prime95 & OCCT. Folding @ home, which I assume is what F@H stands for, is also a very good stress test, but as you mentioned, It will beat down your GPU as well as your CPU so If I am purely looking to test the CPU, It is not my first choice. Stress testing is one of those things. It is absolutely possible to push the stress levels higher with a synthetic stress test than your CPU will ever go under any circumstances during it's life time of normal use. IBT is especially bad in that regard, it is possible to generate so much heat that a good number of CPU's will not pass with a factory cooler at stock speeds. My 4770k was a good example of this, it would fail before the 10th run at stock speeds, stock voltage, with the stock factory air cooler. The CPU was perfectly stable at stock speeds, and in fact with nothing more than a 280mm AIO it was more than capable of a 4.6ghz OC with some decent timings on DDR3 2400 memory. It was just that the IBT stress test put a very high artificial load on the CPU. Which makes perfect sense when you look at what IBT was made for. It was designed to be used as a bench marking utility on super computers, solving Linear equations and stressing the floating point calculations to the absolutely max On commercial CPU's it is an interesting tool, but not one that should be taken very seriously for a home / Gaming PC. Even F@H will not generate the CPU cache stress and heat that IBT creates. Which is also why I feel it is not the best stress testing tool for Ryzen CPU's. It was designed for CPU's with external cache, not on die cache like we find in the Zeppelin die.

After the posted on here from Raja, I don't mind LLC 2 (or even 3 to a limited degree) It helps with voltage drop under load without having to set the base voltage too high. The overshoots on LLC2 are very quick and low, and not really outside of what I expect during normal operation. As I am not setting my vcore to high levels, It really is not much to worry about. Speaking to the low base voltage and drop under load, It appears that others are having real good results using a P State OC, thus far I have not messed with that yet. I am doing pure manual OC's at the moment while I play with memory speeds and thermal solutions.

The more I test Ryzen CPU's the more I am convinced that the cooling requirements of this CPU when overclocked are grossly underestimated. Even a run of the mill custom loop with a 360mm radiator really does not do a good enough job over @4 ghz. The need to remove heat from the die quickly under load is much greater than any recent Intel CPU. It reminds me a lot of my old Opteron 150; which was a great OC'ing CPU in it's day, but only when actively cooled (Phase, chiller, TEC's etc.) I feel Ryzen is very similar. They both have similar voltage scaling, "walls", and that immediate cooling requirement, even more so when the cache is heavily loaded.

I am attempting to convince myself NOT to go fire up one of my old Vaporchill phase changers... but it is getting harder and harder to make that internal argument.

Thank you for your response and nice to have a discussion rather than a "knee jerk" "blah, blah, blah..." wink.gif . It may come across to some that I'm "heavy stress tester" I am and am not wink.gif .

I used P95 very very little on my 1st i5 4690K:-

a) the AVX versions were way to hard on CPU for cooling I had, Archon SB-E X2. I did use older version for a bit, non AVX v26.6, but I found alternative SW I could use.

b) I had read posts by Raja@ASUS explaining on ROG forum how much power it could pull through CPU and could lead to degradation.

2nd pretty much had no P95 done on it. I have also done no P95 on either of the R7 1700s.

Originally I went for RB as my "go to" stress test, there were a few reasons why. One such reason was 8 pack suggested it relevant on OCuk and Silicon Lottery were using it. Both mentioned bin CPUs and retail them as your aware wink.gif . I just changed it's position in my stress regime as highlighted by my previous post, as my CPU was not sensitive to it, for some it is. Example I can recall is finalheaven CPU sample was more sensitive to RB than x264.

And this is the key IMO to improving stress regime for me, to use something that makes my system fail quicker. If I nail that, others fall into place and by this I do not mean I go for the "juggler" with IBT/P95 and so on wink.gif . IBT I have found strange to use (never used on my i5s), "Very High" no issue, "Maximum" and I get an error right at the end. It does not matter if I run 3 loops or 10, etc it will show same error at the end. Another member on Asus Prime X370 Pro has same issue, we are using shortcut set to launch app as admin, UAC disabled, etc. Perhaps it is something to do with Win 7, as most I have seen are running Win 10, going dual OS today.

F@H = folding at home, you can remove GPU slot wink.gif , then only CPU run and vice versa wink.gif . F@H I luv as it's a productive stress test, I get stability testing and a "cause" gains from it wink.gif . This is also the reason I stress test for length on other app. It feels a waste of time if I left the PC running over night and it bombed in f@h as I did not do enough stability testing.

I've always been on air, I plan to go full WC just to gain the experience smile.gif . I have been thrilled on how Ryzen performs in aspect of thermals compared to my i5 4690K. My fan profiles are so much lower for stability testing, gaming/normal use both were the same. Now that I'm not swapping about CPUs on C6H had some decent results as TIM settles.

~1hrs back to back x264 > Y-Cruncher > RB (Room temp ~22C) (Click to show)




For 3.9GHz I need ~1.470V measured on ProbeIt VCORE point to pass x264, the air cooling still keeps it <75C, depending on room temps, etc, with pretty quiet fan profile IMO.

Sweet thumb.gif , each to their own thumb.gif .

I don't sit and use games for hours I can do f@h wink.gif , if I was honest I probably struggle to game for more than a hour a day.

Had that Q6600 since launch and the P5K Premium, most I've ever done in one single run is ~175hrs early this year.

I went 0.950V to 0.962V, then after the intermittent booting issue as suggested by yourself I increased to 0.975V. So far so good thumb.gif .
