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 :)

I have actually added a cooling kit for the pump to my order, in order to try to increase its longlivety.

I actually ordered the new reservoir/pump at a local retailer, and havent received any info on the expected delivery date yet.

I wont call myself an EK fan as such, but the stuff I use from them is very well made, and has run fine. I have had no complaints.
Their TR waterblock is sadly a little lacking compared to others (https://www.youtube.com/watch?v=jjvqPT2CmqI), but off course only when you really push the system.

I just checked my mails, and the XSPC pump/reservoir that broke down, was ordered just under 4 years ago (46 months). I don't think I can actually complain about that as it was not an expensive kit, but breakdowns are irritating nonetheless.

With the new EK pumps MTBF, I expect a longer lifespan. Its also a much more expensive kit.

I have been trying to run seti on my NAS computer that runs based on Centos/Fedora.

I am able to run e.g. World Community grid and Rosetta, but with Seti, after some time, the crunching starts to fail.

In the results for the WU's I get this:

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
SIGABRT: abort called
Stack trace (12 frames)

Is this the same problem as described in this thread?

Nice to hear that your system is back in working order.

I guess your kind of setup really separates the lambs from the goats :)

I am strugling with my setup too.
Off course things break during the holidays, so I'll have to wait even longer for replacements.

Good thing I had a few alternative parts lying around, so that it is at least working, even though not at fast as a few days ago :)

Astropulse V7, choose AVX.

Multibeam V8, choose AVX (it's the best for Ryzen / Threadripper).

ATI, skip it (click on Next), you have NVidia GPU's.

Astropluse v7 (NVidia), enable.

Multibeam V8 (NV Cuda), enable and choose the option with SoG_r3557 in the end (the last one).

The last page with Intel iGPU's skip it (click on Next), they are not relevant for your AMD CPU.

Next window click on Install.

That should do it.

Since there doesn't seem to be any fixes on the way for the invalid crunching of AP on AMD RXxx0 (RX400 and 500 series (possibly also Vega?)) GPU's, I have added the following to the <options> section of my cc_config.xml:

<exclude_gpu>
<url>http://setiathome.berkeley.edu/</url>
<device_num>1</device_num>
<app>astropulse_v7</app>
</exclude_gpu>

This will exclude my RX480 (device 1) from running AstroPulse WU's, but still let them run on my HD7770 (which is device 0).

I would recommend anyone with RXxx0 cards that they do the same until this problem is resolved. Just be certain that you exclude the correct GPU.

Otherwise we risk that invalid WU's get validated, if they happen to be paired with another RXxx0 card.

Well, then you're welcome :)

I sent them 1 GRC yesterday, just to see how it works. Its all very new to me :)

Now I'm just twidling my thumbs, waiting for coins to start rolling in from the pool (it takes time to build up your magnitude).

Its of course irritating that you cant get it to work, and I hope you find a fix.
Its my impression that AMD support on the Linux platform has been much improved (extremely much), much of it because the drivers are now open source (AFAIK), so I think theres a good chance for it to get solved.

I find it frustrating that the works gets done, time is spent, and then the results are invalid. I really hope this gets fixed one day.

Sorry, I was not clear.

They dont error out, they just dont validate. Some of them does, but most of them don't.

It is especially bad when two GPU's of the RXxx0 type validate against each other. The WU's validate, but the data is actually invalid.

Post:
But as you have two RX 480's, and assuming you aren't just running seti, you should be fine.


What appears as two RX480's is actually 1 RX480 and 1 HD7770. Boinc simply displays the best GPU, instead of showing them individually.

I'm running a mix of different projects, and will be fine tuning to get the best payout as I go along, so to get to the point where I can go solo as fast as possible.
I would like to run Seti at about 50% of the time, but we'll see how that pays off.

Regarding MB's on GPU, it has been available from a time long before AP. So you should be able to find it.
And AP's errors out on RXxx0's under windows too (they run fine on the HD7770). There is a bug in the code somewhere (either the driver or the app). For a short time I had Raistmer looking into it, but he seems to be busy with other things.

Yes, it sometimes does look like a scam.

As I read it Gridcoin only recently became this hard to join. Not that long ago you could join, and start making coins within a few days, going solo. As it is now, if you don't have a larger amount of coins, you will not even get paid every 6 months (where the 1.5% interest starts to get deleted).

So this has gotten much harder to get into, and that is kind of sad, as it will scare many peoble away. It almost did with me....

I see that your system is pretty much identical to mine.

So if I can get 20c a day, I would be rather satisfied. I was hoping to do 10.

I have an extra HD7770 crunching also, so perhaps I can get to 21 :)
