My system has now been running 34hrs without a crash.

This with memory timings at DOCP3200 settings, but with mem clock reduced to 3133 Mhz.

This is very promising, and I can live with the small speed reduction on the RAM, if this proves to be reliable.

Well raising VCore didn't help, this time it black screened....

Its allways easy for me to spot, as fans go to max speed, and the computer gets rather noisy. And most of the time I cant simply reset it, I have to toggle the power switch on the PSU.

Something is obviously still not OK...
On 3803 I never saw a black screen on DDR 2400 speeds. I suspect I could end up there on 3805 too.

I must experiment with mem speed to see what I can reliably reach, but will also turn down my CPU OC, to rule out instability due to that.

This is frustrating, the system was very solid on 3401, so having to deal with these things now is SO irritating.

Damn, the system just bluescreened without any warning while I was typing on the keyboard.

The error was something about a system exception, so seemingly not a memory error.

I have turned the vcore to the CPU up a notch, perhaps that can bring the last bit of stability.

I cant say for sure yet, but the system has been running for ~ 12 hrs since I changed the resistance to 48 Ohms, I rebooted the system ~ 8 hrs ago to change the Vsoc, but otherwise it has been stable.

The change to VSOC reduced my core temps with ~ 3 degrees C. More than I expected...

I'm very hopefull that these changes could bring stability, but in reality my dream is for AMD to bring out a working AGESA that fixes these problems.

I suspect their focus right now is the upcoming 2x00 series, and of course fixing the security "holes" reported by the stock market speculating CTS-labs.

Thanks for that info :)

I have reduced Vsoc to 1.05. Anything that helps with stability, and probably reduces power usage, is good.

I just downloaded the latest DRAM calculator. It has been much improved since last time I tried using it. Allthough it still recommends 53,3 Ohm for my ram.

I understand your frustration.

Not being able to find the cause of instability is irritating.

My PC chose to reboot while I slept, I was awakened by the Windows logo/theme music...
So its not stable here with 3805 either. Though I did get a relatively long uptime.

I have tried setting 48 Ohm ProcODT now, will se if that helps.

I'll keep the ProcODT setting in mind, if this proves to still be unreliable.

I'm also hopefull for 3907 :)

Yeah, I wish I had stuck with 3401, which was rock solid reliable for me.

Now I'm hoping 3805 proves just as good.

I can't remeber what board you are using, but I'm sure 3805 is released for it soon.

As a followup, yesterday I installed the just released 3805 BIOS for my board.

I have set mem back to DOCP3200, and have been running the sytem since then without crashes.

Its still early days, as I did have uptimes at above 1 day on 3803 and DOCP3200, but most times it crashed within minutes.

So it _seems_ the 3805 BIOS is an improvement, at least in my setup.

OK, that could be it.

But on my system the HD7770 is Device 0 and the RX480 is Device 1, but Boinc still reports the RX480.

IDK, anyway the BOINC report on GPU's installed is not allways to be trusted.

I have to ask, mostly because I have had similar problems recently myself...:

Did you upgrade your BIOS about the time where you moved the PC?

I have had problems since I upgraded my BIOS from ver 3401 (AGESA 1071) to 3803 (AGESA 1000a). My board is the ASUS TUF B350M-PLUS GAMING.

The system became unstable and would crash. There was no regularity to the crashes. They happened at stock, overclocked, sometimes after few minutes sometimes the system would run for days.

But it allways crashed with a blue screen, never just froze.

As a last resort i set my ram to 2400MHz. My ram is Ryzen certified DDR 3200 (G.Skill FlareX), which I have been running at 3200 since day one without problems. But setting it to 2400 MHz removed the crashes.

I have been reading up on the problem, and its a known problem with the latest AGESA that it breaks some RAM (others get better). And if the ram is unstable peoble have seen corruption of their OS'es.

I am a little irritated that my, rather expensive, ram is now running below spech, but at least my system is now stable.

I'll wait for a fix, mostly because a downgrade is not really very straight forward on my board.

An update on my Gridcoin experience up until now.

I have been Gridcoining for about 45 days now, and earned my first stake of coins today. All in all I have made Gridcoins that have a value of about 40$....

It has been a steep learning curve, and I'm still not sure I understand all the inner workings of the system. I probably do not.

The original plan was to donate all my earnings to Seti. That is still the plan, but I have had to modify it.

First of all I dropped riding Solo for a start, and joined a pool, which has steadily been paying since then. Slowly rising to about 15 coins a day.
I still run 20% Seti beside the pool in solo mode, to keep up a little RAC, so I could probably make some more coins, but I like it the way I have it set up.
I have also tried getting free coins from the so called "faucets", but they pay very little, and are often offline, so I'll probably stop doing that soon. Its not worth the effort.

My plan now is to keep the current setup until I start staking coins regularly, like once every 14 days or so.

Then I'll start increasing my solo crunching and reduce the pool crunching, while still building up coins. When I get enough coins that I stake once to twice a week (on average), I'll go full solo.
From then on I'll pay my earnings to Seti, but keep a high enough coin balance to keep up the staking frequency.
As dificulty keeps going up, I'll have to add coins to my wallet to keep staking often. So not all coins will go to Seti, only the surplus not needed to keep up my staking interval. Theres a balance there that will need to be found.

But in some time, most probably 3-6 months, I should be able to pay Seti a small amount of coins every month. How many coins, and what their value would be, I have no idea right now.
That will be up to factors such as how fast the dificulty rises, how much a Gridcoin is worth and probably other factors.

My computer setup, could at some time prove to small / slow to keep up with difficulty, and then my staking interval would get longer (and longer, and longer).
I'm not going to update like crazy to keep up with this, I'll upgrade when I feel it necessary, and that is still mostly driven by the computer games that I play on the system.

But with a little patience and some effort, I'll be able to support Seti a little bit in this way :)

And even though there has been some work and a lot of learning, I have found it fun and sometimes very interesting to get this thing going.

I dont have any qualms either.

I dont have exactly the same settings as you, but am running at the next highest setting for the core, and standard for the SOC.

And my core voltage is now at 1,25V, so there's room for more there. Going beyond 3.8Ghz, starts to demand much more voltage...

Perhaps I'll try to up the SOC a little (its at 1.1V). Although I'm running the mem in spec, it is a overclocked setting when you look at the system data.

My system is in a room where I do lots of other stuff, and is also my main computer for doing "real" work, so I want it to be quiet.

Your comment about black-screen crashes are very much in line with what I've read elsewhere.
Just wanted to mention the C-state thing, in case that could help. Cant hurt for him to try, just don't get the hopes up too much.

My system was, speaking of it, crashed with the black screen this morning....

So stabilizing the GFX gard seems to have brought back the other bug. Or rather it was probably allways there, the GFX card just crashed first :)

I have upped the core voltage for the 1700 with 0.05 Volts, time will tell if thats enough. I'm not worried about temperatures, theres plenty of headroom in the cooling setup.
I would like to keep the computer somewhat queit, which is off course made harder by me wanting to overclock everything :)

I don't know if I can be of any help, but I have had some stability problems on my own Ryzen system, that I now seem to have resolved (fingers crossed).

I run a Ryzen 1700 on a ASUS tuf b350m-plus gaming with 16Gb DDR3200 ram (G.Skill F4-3200C14-8GFX). The mem is guaranteed for 3200 with Ryzen, and has been completely unproblematic. My graphics card is a RX480 (and a HD7770).

Today I run the Ryzen at 3800Mhz, on a watercooled loop where it sits at 60 - 66 degrees C. I could probably push it more, but it really starts to want a lot of core voltage, and I dont want to push the motherboard too hard.
But the problems below all happened running at stock too, with much lower temps.

I sort of had 3 different things happen.

At first I had a black screen freeze, where the system turned of the monitor, and the system was unresponsive to my input. I could see some HDD activity though. This would happen completely random. Sometimes the system ran a few hours, other times more than a day.
Following some thread in a forum, I found a guy that said turning of all C-states for the CPU in BIOS, had solved the crashes for him. It seemed to help for me too, but I cant be 100% certain, since I installed a new BIOS a few days later, that could be the fix too. But I havent seen these crashes since turning of C-states for my CPU.

After this I had some system resets. Working at the system, the system would suddenly reboot. No warning of any kind.
I went ahaed and turned up the load line calibration for the core voltage, and the system has not reset itself since then.

The last crash I had, was harder to fix. Working at the system, or sometimes being away from it, the screen would freeze, with a constant picture. I couldn't move the mouse, the system was completely unresponsive. Reset / power toggle was the only way to restart.
This one really bugged me. But while working with my graphics card I noticed, that the core voltage to the GPU was lower than what the driver requested (I used HWiNFO64 to see these things). Consistently about 0.03V lower actually.
That doesnt seem like much.
But I could see 1.144V being requested (with voltage control in the driver at automatic), and the measured voltage was 1.110V. I changed the setting to manual voltage. That specified a 1.163 GPU core voltage instead, and now the core voltage is measured at 1.138. This has completely removed the crashes.

I cant claim 100% stability yet, since I made the last changes friday evening, but the system hasn't crashed since then.

Anything is relative as they say, but my case does have a few years on it.

Its the original Antec P180, which is still a nice case. A case that was originally build with low noise in mind.

And in that regard its still a good case.

But its correct that the 5 1/4" bays are going away, together with the CD / DVD / Blueray (And before that the 5 1/4" floppy and HDD) drives. Just evolution doing its job.

I have considered replacing it, since many new features are lacking (USB3.x for instance), but I think I'll keep it around for a few years to come :)

Allthough this is originally RueiKe's thread, I will post a followup.

All the parts have arrived a few days ago, and I have been installing and testing a lot.

I had some dificulties along the way. I destroyed my old radiator, so I had to get a new one (I got a alphacool ST30 360, mainly because I could have it here in 1 day).

While I was at it, I decided to replace my old tubes, as they had a lot of miscolouring, and had lost some of their flexibility.

Its up and running now, and I can say that the Eisfach is doing the job nicely.

Even though the new radiator is less efficient than the old one (because its half as thick (the old one was 60mm)), the clearly increased flow from the new pump, has made my temps stay more or less the same.

For now I can recommend it to anyone needing a reservoir that fits into dual 5 1/4" bays.

I have found it easy to work with, and there is a lot of flexibilty with all the extra ports, so you can set it up in many different ways.

Since the retailer couldn't promise me a delivery date for the EK reservoir / pump I have cancelled the order, and have gone and ordered an Alphacool Eisfach with a single Laing DDC pump.

Basically the same pump as in the EK reservoir, but with the cooling ribs included, and in a bigger reservoir. They could ship immediatly, and this setup is 25% cheaper.

So I'm looking forward to getting this and installing it.

I was actually looking at the Alphacool Eisfach, that uses that exact pump.

It does seem solid enough.

Maybe for the next build :)
