Okay, went from a Gigabyte B450 Aorus Elite to an Asrock B450 Steel Legend. Nice RGB.
Had also bought a Cooler Master Masterliquid ML240L RGB water cooling, but am returning that to the store as I cannot manage to get it locked onto the CPU socket. The screws with which you hook the hooks around the socket are weird. They start with some screw thread, then there's approx. 3 mm of nothing before the thread continues. Once the hooks are hooked onto the socket however it's impossible to bridge the 3 mm of nothing. I've been at it for two and a half hours. I quit. I give up. Put the air cooler back on, three minutes work. Really.

Am now running Furmark on CPU for stability testing. CPU is at 66C and stable.
Together with Furmark for GPU max 68C.

But temps never were the problem, something else was. So will do more testing after dinner.

Edit: changing the motherboard has deactivated Windows. Any way around that besides having to buy a new copy? I already used my previous Windows 7 Ultimate key
I'm certainly not forking out €259,- just because I changed my motherboard, Microsoft!

Edit3: so I found it... you need to link your device to your Microsoft account. This means that tomorrow I have to put the old motherboard back, link it to my Microsoft account, then change the motherboard again, and upon re-entry link the new motherboard to my device. But the easiest way they want you to follow is of course to buy a new license. Which if your mobo is fried you will have to do.

Charlie, present day BOINC can be installed on a domain controller as long as you install it as a user installation. That problem where the installer would balk because it couldn't make the BOINC limited user accounts is afaik only still present for service installs. The non-service install no longer makes those accounts.

So try 7.14

Well yes, pretty sure it's the motherboard. Started the system fresh this weekend, opened Firefox, started a video on YouTube. Within 5 minutes a BSOD. In the middle of the gathering of information for the memory dump, the system rebooted. So I don't have a dump file. I do have an error 0x00000109 with sub error 101, which points to a general pool corruption. Which could still be CPU, memory or motherboard, or a driver not being Windows 10 compatible. Let's rule out the last as it's all new hardware, all new Windows 10 Pro, all new drivers.

So I will go negotiate with the store to give me an Asrock motherboard as replacement, because when I bring this motherboard back, they will RMA it to the manufacturer and I will have to wait until they say it's broken or not, which can take several weeks. Meaning I don't have a system next to my TV then as I brought the old system to my ex already. I don't mind buying a new board.

Timing out makes sense, but I'd hoped to see what 24 hours of compute time was worth, credit wise.
Credit isn't based on time, but on the amount of floating point operations the task took. This means that a slow CPU that takes several days to complete such a task will get as much credit as a fast CPU that took minutes.

Astropulse tasks take in the region of 400+ credit per task.

When the secondary database server isn't playing hide and seek with up to one day running behind on the primary server, in general it takes just 24 hours for a task to be visible on the server once it got uploaded, reported, checked against its wing person's outcome and validated. So it can easily be that your wingmate had it reported earlier and by the time you looked in, it had validated and been deleted from the lists already. It's impossible for the project to keep all tasks forever on display, because at the moment they're already in uncharted territory for database sizes.

That said, do make sure you were watching the right system.
Your ID: 8889124 shows an AP that took close to 10 hours, whereas your ID: 8891814 shows one AP that took 5 hours+.

Can tasks just as that disappear?
Well, maybe if they were timed out already. Then their result was removed from the server already by the time you uploaded & reported it.

$4K for a Threadripper CPU????
Their EPYC Rome is more expensive, at $6,950, but it can do more as well (address up to 2TB of memory across 8 channels, use buffered memory, be used in dual sockets, address 162 PCIe 4.0 lanes, etc,)

Unless you want to wait for the Intel Cooper Lake-AP CPUs, but where the TDP of the EPYC is up to 225W, on the TR up to 280W, bring some beefy icebox for the Intel with its expected TDP of 400W !!!

Not the memory, as I got a completely new pair at the store today. It's unlikely Corsair managed to get 2 pair of bad memory to the same small shop. ;-)

I'm thinking it's the motherboard as well and I don't like Gigabyte either. Them and MSI are my bane. Asrock is my brand of choice.

Gigabyte hasn't gotten that memo. The only colours on the motherboard are in the RGB in the logo, the rest is 50 shades of black.

You are putting the two RAM sticks in the proper slots aren't you? Refer to your manual. Normally you use DIMM_B2 and DIMM_A2 slots for two sticks. To get the memory timing signals correct, the DIMMS need to be a certain distance from the cpu and of equal electrical lengths.

The motherboard manual (if you can call this rag that) says:
"The four memory sockets are divided into two channels and each channel has two memory sockets as follows:
; Channel A: DDR4_2, DDR4_4
; Channel B: DDR4_1, DDR4_3"

And then a schematic that shows you can either slot in 1 and 3, or 2 and 4 for dual channel .
I asked about that in the store and they also said best try 2 and 4 first. I'm doing that, but the system still isn't really stable. Had several Firefox crashes already. Luckily Cortana came back, yesterday I had the search open to a black screen all day, so I had to start everything via Run.

The Security and Maintenance Reliability Monitor is full of red circles with white X's. Even the Ryzen DRAM Calculator managed to hang itself and had to be forcefully closed. The hiccup, where the mouse would pauses for several seconds seems to be gone though. Perhaps that the BIOS update did that. And luckily I remember that after a BIOS update everything is reset to defaults... which on this motherboard means that the boot option goes back to legacy, which is a tiny little problem if you setup Windows to use UEFI.

By the way, this system - the Ryzen 2700X has just got 16GB RAM. I also forgot about that earlier. But then today I was doing 6 things (?) at once. I question myself as I can't remember. Just as again I couldn't remember where I parked my car, and two hours after I got home my parking app notified me it was still on. So uh, that kind of day. ;-)

I agree, but have now exchanged the memory. Two new DIMMs in the slots. The store normally sends them away for testing, but they know me and changed them over without problems. They also think it's a motherboard problem.

But let's just first see for 24 hours what this does. Not jumping to conclusions.

Oh, I forgot you are running Windows 7 32 bit.
Where have I said that? I don't think I ever owned a 32bit Windows 7. All my Ultimates were 64bit, so they can be easily transferred now to Windows 10 Pro x64. Which is what I am using.
I'll make a screen shot later on, have to now go test the individual DIMMs anyway.

Here you go: https://photos.app.goo.gl/qoc7dbyG3q9dWXgF7
That's when I fill in 3400.

The plot thickens. Tested both DIMMS individually in the first slot closest to the CPU, both gave errors. Then on a whim put one in the second slot... no errors. Also not with the second DIMM.
So broken motherboard then. My luck. I knew I didn't like Gigabyte for a reason.

The plot has jumped out the window. Tested one DIMM in all slots, no errors. Testing the other DIMM in all slots... no errors. What? How?

Well it doesn't. At the start it'll tell you that because of Windows limitations you can only input max 2GB to 3.5GB values, although you can run multiple instances at a time. Try to input 3500 and it won't run. 3400 either.

Thanks. Although the program is a bit unintuitive to use (it doesn't want to use values above 3200MB for some reason), I dropped back to 1024MB and hit an error in the first 3%. Rebooted into the BIOS and found that XMP was turned off. Turned it back on, back into Windows, memtest. It now came to 5%, but yet again an error. SO I suspect I have one or more bad DIMMs. Have emailed the store already, will await their answer.

That'll have to wait as I am doing a full scan of my hard drive first. It's at stage 5, 13% and going to take at least 2 more hours to get through that.
I'll go play some more of the crash prone Breakpoint. :)

What memory test are you running?
The default ones from Windows. It found no problems.
Sounds like unstable memory problems or not enough SoC voltage.
There's also a hiccup at times where mouse and keyboard don't work.
Core voltage switches between 1.3375 to 1.4500V per core, although I do see values as low as 0.372V in CPU-Z. But since that just says Core Voltage, it doesn't say which core does this. In Core Temp I can see the voltages per core, they don't go as low.

I didn't change much in the BIOS, just set XMP profile 1 so that the memory runs at 3,200MHz.

Ran FurMark for CPU together with FurMark for GPU on the new (2700X) system today, still stock cooler. Max temps 76C CPU, 79C GPU. I like it. Especially since this system won't get those temperatures as it's merely for streaming TV series, films and Netflix.

But the system isn't stable. I don't know what's going on, I haven't been able to get 5.1 sound working yet (only two speakers work).
Have had Firefox crashes while it just had two tabs open, one downloading a driver, the other running an LTT video.
Then just moments ago a BSOD (Page fault in nonpaged area). So yeah, it's not stable.

I have the feeling the videocard is damaged, because of all the HDMI problems I had yesterday. Solved those with a new cable and HDMI port 1. But still.
I'll run DDU later on, get rid of all videocard drivers, then only install 20.1.4
Also have a patch for the RealTek 5.1 problem, will try that as well. Just waiting for a memory test to finish. 90% there.

Okay, then it's the Prism I have. It's the exact same cooler that came with the 3900X, same part number. And it has nice RGB

I wasn't trying to install Windows 7 on that system. It already had Windows 7. Mouse and keyboard worked fine in the Windows start menu, afterwards no more.
So I cleaned the hard drive and have now installed Win10 Pro on it. Am in the process of updating it. Will see what drivers Windows will put on here, nice test.

So far max temp I saw with Core Temp was 60C, but general idle temp is 37C. I may have to tinker around with fan controls to get more out of the Wraith Spire.
But let's repopulate the drive first. There's 2TB of emptiness staring at me.
