I now have the above with 90% threads running. 6 gpus + 8 cpus. This is the stock setup I have been using.

If the RAC graph curves into a steep dive tonight, then we are going to have to come up with a compromise of some type because some over-committing of the cpus may increase total production.

Tom

Do you really expect RAC to change that fast????? I have never seen RAC change overnight. More like a couple of days if that fast/


When one of my two biggest boxes crashes and I don't catch it, it takes 5,000-10,000 RAC off the top. But that is when it is down for hours or even overnight.

As soon as I tried Tbars proposal, the RAC that had been sliding lower and lower suddenly became nearly flat. That was before I upgraded the cpu cooler and started running 4.0Ghz on the cpu.

If there is a massive reduction in total put through then I expect the graph to drop a lot. But if it is "dinky" reduction then like you said it can take days......

The processing times of the cpu tasks track nicely with the level over commitment. So the question is where is the "optimum" over commitment that produces the highest total production.
I expect the cpu processing times to mostly return to the 47-57 or less minute range now.
Right now many of the cpu tasks are taking over 2 hours. So what I am looking for is more than 8 cpu threads but less than 14 threads that slows the cpu processing to maybe an hour and produces greater total output.

Or as Zalster has commented or recommended, just set a max_concurrent statement in app_config so that the total cpu usage is 65-90%. I like around 65% usage as that keeps cpu_time within a couple of minutes of run_time. Follow Juan's formula for a spoofed client, add the desired number of cpu tasks wanted to run to the total amount of spoofed gpus to arrive at the designated max_concurrent statement.


I had this running previously:

<app_config>
<project_max_concurrent>48</project_max_concurrent>
</app_config>

Which is the gpus 6-> 32 spoofed setup.

And with 100% of the cores/threads enabled in Boinc Manager, the RAC graph was dead flat.

I have just re-patched to this:
app_config>
<project_max_concurrent>48</project_max_concurrent>
<app>
<name>setiathome_v8</name>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
</app_config>


I now have the above with 90% threads running. 6 gpus + 8 cpus. This is the stock setup I have been using.

You know my answer to this. Set CPU to 100%. Add a <project_max_concurrent>15</project_max_concurrent> to your app_config and see it that improves your throughput. And let's not get into the same old arguments. Just test it and see how it goes.


I started a test about the same time I posted the question earlier today with cpu cores at 90% and the defaults project_max for gpu spoofing. And right now the RAC has stopped falling (I ended up with 6 gpus instead of the 9 I had for while because of the new Aus C7H mb).
So either I am experiencing some LAG issues from previous changes or it actually is processing faster. I dunno. Will have to run it a while....

Tom


Well, the RAC is still climbing. And once I have my new cpu cooler installed I can OC the cpu.

I suspect what is going on is
1) The gpus are still running "at speed" because of the -nobs
2) I have nearly doubled the number of cpu threads that are crunching cpu tasks. And while they have slowed down, they haven't started taking twice as long.
So #2 is producing a net gain.

Tom


I got the oversized cooler installed a Friday. With major assistance from Keith it ran over night without crashing at 4Ghz. And seems to be stabilizing at about 375,316.07 for the RAC.
I need to go look at the latest cpu tasks. When I looked at them yesterday, the wallclock time and cpu time will not tracking real closely.
It maybe that there is a compromise like that will increase production while while letting the cpu tasks times come closer together.

I will try going from 90% cpu cores to 100% to see what happens today. Later I will try 90% and 1/2 cpu to 1 gpu (its 0.10 cpu to 1 gpu now) and see what happens to the RAC.

Tom


So far the RAC has been flat. I am being nagged to go back to 1:1 cpu to gpu on another thread. Guess I will try that tonight and see what happens.

I was looking again at your sensors readout. I don't think you got around to installing the socket fan I talked about have you? That would help stability a lot.


It turns out I will need to buy the suggested fan. The ones I have available are large enough I was having trouble installing it. I have a bar on the rack that limits how far over I can install the fan. I will go back and re-read that part of the thread then order a couple three. I expect to run Amd cpus for years so I want them a cool as I can.

It ran all night. !!! At 4Ghz !!!!!!!!

Tom

ps. Yes I am still thinking about a 2950x..... "more cores...." ;)

Try to run overnight on that 1.32V and see if it holds up.


Since I am tired of screwing around with it and it is still running nearly an hour later..... its a wrap (or is it a rack)?

You change from Auto to Offset. Don't change "sign" It should default to "+" then move to Voltage Override and just keep hitting the "plus" key on the ten key keypad to keep adding 0.00625V to the offset until you to total up 0.03125V or in other words 31 mV to the 1.30V to get to 1.33V or keep adding. The smallest voltage change possible is 0.00625V because that is the LSB value in the D to A conversion.

Save BIOS and reboot and check your readback voltage which should now be 1.33V.

I am going to reset everything, go back to DOCP ram settings, 40 cpu multipler and see what happens to the volts and heat. If it will run LLC auto it should be cooler (I read someplace :^)

With the offset at 0.35~ I got this:

So the LLC 3 and maybe other stuff made a voltage difference. And it is a tiny bit cooler.

The highest cpu voltage offset it will let me do is 0.45 so will try that next.

1.30V isn't enough for BOINC load at 4Ghz. If Auto is setting 1.30V for the 4 gig VID values, you are going to have to use an Offset for Vcore instead of Auto. Change to Offset for Cpu Voltage and input 35mV to 50mV of additional voltage. As I have said previously, you need to see Vcore under BOINC load of around 1.33 - 1.35V for 4Ghz on the C7H and 1002 BIOS.

1.27V is fine for 3.7Ghz. Question was what was/is the voltage at 4Ghz. Unless you have the crappiest cpu ever produced, a 2700 should be able to run 4Ghz. Again the cpu voltage needs to be around 1.35V.


Ran all day at 3.7Ghz. Got home from work.
Had a system update (security only and core image).
Booted it back up to 4.0 Ghz. Without anything accept the D.O.C.P. Standard on the ram. Everything else is auto.

I see your memory running at XMP voltage. Are you running them stock? Why don't you bump them up to 1.365 -1.37V.

I had limited time this morning so instead of relying on some of the other bios presets I used the DOCP Standard which runs ram at 3200 with all the other stuff that appears to be "stock" overclock.


Do you know why you are crashing? Have you looked at the logs to see what the error is?

The only log I look at regularly is erased when Boinc is restarted. I will be researching the why as I dig out the other Linux info that has moldered/disappeared in my head.
The OS did throw a report to developer error that I submitted this morning. But since there was a core image update I went ahead and updated that.


Do you ever run a stress tester at your new attempted clock frequency to see if your settings are stable? A half hour of Prime95 small FFT's will quickly show errors if you don't have enough voltage. A half hour run of stressapptest will prove that your memory is stable at the attempted clocks.


I have regularly had Seti crash things when I over do the OC sets so until now I haven't seen a need.

With WOW under way, I am reluctant to take the time when I don't have them already setup and had practice using those stress testers.

I am going to babysit the machine at 4.0Ghz all evening. If it doesn't crash by bedtime I am hoping it will run overnight.

Meanwhile back to the log research.

Post:
What is your Vcore at 4Ghz loading? You should be somewhere around 1.35V or a bit lower. I end up around 1.33- 1.34V on Auto at 4.025Ghz. LLC on Auto. Power delivery at 120%. On 280mm AIO cooling though compared to your air cooler. On air, you need to run LLC2 or LLC3 probably. The LLC is what forces the temps up as it doesn't let the Vcore voltage droop as much and the power usage is greater. But if the LLC gives you more stability without dropping the host offline, then you just deal with the sligher hotter temps and don't go as far with the core clocks.


Not sure what it was. It crashed during the night. I love the cmos clear button.
Everything but the multiplier are auto. Plus preset for D.O.....?

I would think it would lead to instability. The current Ryzen 3000 BIOS doesn't even qualify as an "alpha" let alone a "beta"

Get a better cooler on the cpu and then just set the multiplier to 4000Mhz and leave the CPU and SoC voltage on Auto. Set LLC to Auto and the cpu voltage under load should end up around 1.34V and run around 130W under load. Should only run around 65-70° C. under load.


Whispering...... got the new, gigantic air cpu cooler on.
After a some minutes getting the gpus all happy again (I removed the #2 PSU/harness for later deployment). And confirming the temps were reasonably stable/low at 3.7GHz I jumped it to 4.0Ghz.

Normally it will crash withing 3-5 minutes. Since it is still running. I am presuming I am stable.

I installed the llc 3, phase control optimize, current delivery 120% parameters.

May need to try w/o them because the temp has gone up some..... Its at 74C right now, and at 3.7Ghz it passed 85+C regularly with the stock cpu cooler from Amd.

Anyway, lets see what happens to the RAC overnight. It had flattened out again. But at least it wasn't dropping.

cool!

just make sure you get the right CPU coolers. that board is Narrow-ILM.

I use these guys, you'll need 2: Supermicro SNK-P0050AP4

Excellent/quiet heatsink.


I think I have the quietest available narrow-ILM heat sinks already from a previous MB experiment that expired when the MB stopped booting :(

Even so, they are louder than the regular heat sinks.

Found a
Supermicro X9DRX+-F Intel C602 Dual LGA2011 Proprietary Motherboard System Board
for $499 (used,[new, open box]). Ordered it.

After WOW I will start transplanting the guts of my Intel server onto it as well as all my fastest gpus.
It will go into the same Mining Rack Ian is using for that MB.

After significant testing on an ASUS Crosshair 7 Hero MB (using a 2700 cpu) I can say, so far, I can only get 6 gpus to boot. It dies in the POST when you go for 7.

That said, it has a lot of VRM resources and I expect to get high, stable cpu OC out of it (waiting on a new cpu cooler).

It turns out there is a difference in the # of gpu's you can run on a Biostar TB350-BTC.
With a 2700 cpu you can run 9 by using the "Over VGA?" in the mining toggle in the bios.
With a 2600 cpu you can only run 7. The "Over VGA?" toggle won't work (it boots back to the bios).

My current guess for running a Biostar TB350-BTC is run a Amd Ryzen 2700/2700x whatever you have. Disable the CPD and run "everything" else on auto except your ram which you can run using the XMP profile.

This should result in a pretty cheap, stable Seti cruncher with upto 9 gpus.

I have had significant trouble trying to overclock the cpu. But running on auto, the gpus still crunch as fast as they do.

I am NOT confident you can run an Amd Ryzen 9 3900x or 3950x on this MB even though the MB does have a Ryzen 3000 bios upgrade available (and that upgrade will run Ryzen 2600/2700 cpus.
