We're still waiting on a Turing card to show up here. Supposed to be one next week on Einstein by Archae86. In that thread Mikey says someone already has one running on PrimeGrid. Says it is faster but not OMG faster. Same generational improvement seen on every new card family release. Someone else did an analysis of the efficiency of the Turing CUDA core compared to the Pascal core on PrimeGrid tasks and came up with 46 -50% faster.

I usually find the best in depth analysis of cpu and gpu architecture done by the writers at AnandTech. You will find the cpu and gpu roadmaps of the various vendors there.

Yes, install the wine-stable package. My problem was simple user error. Not paying attention to what the program was showing me. I just had to input the proper gui_rpc_auth.cfg password on the BoincTasks "Computers" tab when I did the "Find Computers" search for computers on the network. BoincTasks works well under Wine. Not quite as fast in pulling up the Messages and History tabs under Wine compared to native Windows, but very usable.. You can reduce the amount of lines shown to speed up the refresh.

It is clear I am not clear here (sorry for the rythm).

Tom, does that mean you can't find the rhythm ??? Boom - shaka laka boom - shaka laka ;^}

Or that you didn't have the time to do the rhyme?

Use BoincTasks for the number of tasks per day or per week completed. Use a Kill-A-Watt meter for the cumulative kW/hr used during a 24 hour period.

Yes, any AMD cooler before the Ryzen Wraith coolers were launched are not worth using other than as a paperweight. The current Wraith coolers that come with Ryzen+ are eminently usable even overclocked. They even are stock on the X series processors now. No aftermarket cooler is needed for general usage and occasional overclock boosting.

That's a flaw in a really old BIOS. Long since solved in the current BIOS'

Is the recovery method you talk about is for users running 2 nvidia card? (i only use one so..)

No, the recovery method is for installing the official Nvidia .run file downloaded directly from Nvidia. Not for installing the drivers from the ppa.

. . Just very frustrating. Others are blaming the problem on Lubuntu itself and recommended using 'full' Ubuntu, but since they are both using the same 18.04 kernel I am not convinced that will be any better; and in keeping with the thread topic I am trying to achieve a setup that will be most comfortable for new Linux users coming from a Windows background. Which is why I am now considering trying Kubuntu but maybe using the 16.04 kernel.

There's more going on than just a kernel running. You also have to have a desktop manager running the system. I think your desktop manager has more to do with your issues than any kernel.

Out of curiosity what issues do you have?
I had to RMA my first R7 1700 because of the segfault problems the early batches had when doing hard computing using multiple thread workloads.
Another problem i think alot of people had is the system crashing when idling, i think this was either a kernel fix or bios fix, can't remember, never had that problem tho.

I too RMA'd my first Ryzen 1700X week 1705 chip. The replacement week 1738 chip was a dud though compared to the original with regard to memory and core overclocks. Definitely the original chip was better except for the repeated segfault errors.

. . The problems are with the latest kernel, but I am running an ASUS X370 mobo so I am wondering if there is an issue there. AFAIK Keith is running all x470 mobos.

Stephen

? ?

Nope still running my second X370 system too. Though every day I look at it falling further behind the X470 systems, I threaten to pull the plug on it and upgrade it to X470.

Is there any thread i should look into to set up keepP2?
I would guess i need some script of some sort,like i will have to boot at stock clock, and maybe have a script run P2 then apply overclock after right?

No, no special script unless you want to write your own to keep from having to type in the command every time or do the copy/paste thing.. The document file in the zip archive explains the syntax. If running just a single gpu, then it is a simple bash command of ./keepP2 in a Terminal window, then just minimize the window and let it run in the background. If running more than a single gpu just add in each next device in the command.

I normally run 4 bash scripts when I start up the computer for crunching. First is the keepP2 command, then I start with a root Terminal window and run my unrestricted command which sets up the cards for overclocking and fan control. Then I run my overclock script which sets up each card for the desired overclock for each card, sets the fans to 100% and turns down the LED lighting, Finally I run my script which sets the priorities and affinities for each of the cpu and gpu applications I run. Then minimize that window and start up BOINC.

You can search on my posts in this thread for my scripts which I have posted several times or I can PM you the scripts if you are interested.

Nope, we don't have enough. But Eric has been pretty good lately in coming in on holidays and weekends and loading more tapes. Or he has been able to get the colo staff to load more tapes on his direction or whatever.

I'm going to have to wait on pulling the trigger too. Still want to put a TR 2950X build in front of it. But if and when I do pull the trigger, it will be either a EVGA AIO RTX 2080Ti or a custom block version.

I agree and why I wanted to hold off any "is it worth it" comments until I saw compute performance tests since its gaming performance is moot in our use case. I think it will come out pretty good regarding credit per watt once one of these show up in Shaggie's charts. It is only pulling about 20-40 watts more than the 1080Ti in these tests. I would like to see how it compared to the Titan V but it looks like Phoronix never did a compute test on that card.

More benchmark tests available, this time concentrating on compute performance of the RTX 2080Ti. The Phoronix.com tests had some good CUDA and OpenCL tests that probably are similar enough to make some conclusions about how the 2080Ti would perform on similar Seti work. Also some interesting performance per dollar charts comparing RTX 2080Ti versus GTX 1080Ti.

NVIDIA GeForce RTX 2080 Ti Shows Very Strong Compute Performance Potential

Is the computer "black screening" or just freezing up with no video output and no mouse or keyboard response? Normally means insufficient cpu Vcore voltage for BOINC crunching load. Try increasing the Vcore or add an offset. The memory might be getting used up since the main memory is used by on board graphics in the APU. Try increasing the Vsoc voltage also since the onboard video puts a larger strain on the memory controller.

Tom's dyslexia kicking in as usual. He meant XFR which is the AMD auto boost mechanism normally enabled on the chip in the BIOS. You could try setting your screensaver to none or blank instead of using the installed Seti screensaver. Unless you like to watch the pretty pictures.
