My Ryzen isn`t running very hot.
I usually have 51° to 55°C running 6 instances on CPU plus GPU.
I have a Noctua D15 installed and its not even running full load atm.
Of course you are overclocked with your 1700 which is different.

I have Linux running on a 64 GB USB 3 stick. That was just 60 Bucks.
It runs smoothly and very fast.
You just need some time to read thruough everything.

A warning is at a place here (Eine kleine warnung).

Boinc and the seti app both write to disk (USB). BOINC writes just as it is told to do in the user interface (once in a minute or so).
The (GPU) App writes checkpoints hundreds of times a second unless it is modified in the source code to not to do so.
Please make a backup for your own sake.

My NV code will not do any checkpoints in the next version. A restart of a task will start from 0% but that is not so a big loss, is it?

Viel Grüss,

When was the last time you dusted that unit out?:)

No, the HAF922 is a skeleton now. I am a terrible packrat. I never throw anything out and castoff hardware takes up an entire room. What I usually do is survey the bits and pieces on the shelf gathering dust and see what I might have to procure to make another system. That is the evolution of the new Linux special app machine. I have kept relatives in computers since the late 80's.

The working computers get blown out at least every couple months or earlier if I am installing hardware or something. The cat hair from 3 "children" gets into everything.

Thanks. Wondered that's all. I was trying to reconcile the case floor grommets but the hard drive cages looked familiar. From memory as I hadn't bothered to unbury the case from the closet.

Nice! Curious ..... what case is that? Is it by chance a Coolermaster HAF922? Looks very familiar since I have that case still in the closet as a cast-off.

Win 7 is up and running now.

Looks much better now.
There is still a difference but not that much.

That looks exactly the same for Arecibo VLARs on the AVX app for me. I find the BLC tasks run about 30 minutes faster than the Arecibo.

My runtimes (max) are around...
750Ti - 13.5 min

13.4min done & something happens. That's a lot of crunching to redo for the sake of a checkpoint.

I have been scratching my head on that comment from Petri for awhile. Sure it would be fine to not checkpoint for a dedicated cruncher, but definitely not for a user that has 'only when idle' selected. Most of the time mine are set to 2 minute checkpoints, since they seldom turn off.

My runtimes (max) are around...
750Ti - 13.5 min
980 - 5 min
1070 - 4 min
1080 - 3.5 min

I think a command line switch to turn it off, or reading user prefs for idle flag (to turn it on) would be required. I'm guessing the reason you would like to do this is to save a little processing time recording those values.

But I do think for any non-dedicated machine it would render any small improvements gained very little compared to what would be lost by most people.

I would lose an average of ~5 minutes on my 750Ti for each restart, but for me it isn't bad since My AMD also is sitting on day 19 of uptime, so very little. But compare that to having an idle time set, and it could add up to hours of lost work per day.

Adding a command line option would be the way to go, but that is probably a heck of a pile of coding for little change.

My NV code will not do any checkpoints in the next version. A restart of a task will start from 0% but that is not so a big loss, is it?

If you're running a TitanXp, no.
But if you're running less capable hardware that takes more than a couple of minutes to process a WU, then yes, it is a big loss.

Yes, as my usual wont ...... I always try to overclock my AMD processors. Just to prove my bang for the buck philosophy. I was curious what you were cooling with. The Noctua NH-D15 is plenty for stock speeds and I'm sure it isn't even breathing hard. I think I have settled on 3.875 Ghz for the CPU since every time I attempt 3.9 Ghz it eventually black screens. I refuse to crank the voltages to insane levels to achieve that clock speed. I just don't want to deal with the temps. I did reconfigure the AIO yesterday since I wanted to check the thermal paste application. I had read that the pump barely moves any fluid around and has minimal volume and has a difficult time dealing with a gravity head so I moved it from the roof exhausting out to the front pulling air in from the outside. That has improved the temps by about 2 degrees on average and the pump is basically level with the input of the radiator. I know I should just bite the bullet and go with a proper custom water loop but I just can't find anything that will fit comfortable with least amount of upset in my case. I would have to add the cost of a bigger case along with the custom cooling components. I just bought the new case for the Ryzen build and would like to get my moneys worth out of it for the meantime. I am now running 58-62 ° C on eight CPU jobs on the physical cores with an occasional spillover CPU job on a virtual core when a MW or Einstein task moves in and four GPU jobs on the dual 1070s.

I would think that one of the benefits of the SSE4.1 app over the AVX app is that it doesn't work the CPU as hard leading to better thermals. That is a plus for the hot-running Ryzen processor even with the better power consumption over the FX processors.

I need to get off my duff and get a Linux system put together from my spare parts. The only thing that has me dragging my feet is my cast off computer case which is really not conducive to putting an AIO into. I should just bite the bullet and accept that I might have to spend some $ for the build.

I always thought that from the notes in the Lunatics installer that the SSE4.1/2 app was supposed to be faster than the AVX app on AMD processors. Unfortunately, there never was a SSE4.1/2 SETI V8 app developed for the Windows platform. Because of Urs, Linux users have that luxury now. Seems that the comment about the SSE4.1 app is faster than the AVX app on Linux as was suggested.

And of course, most Linux installations always seem faster than the equivalent Windows installation on the same hardware. Just up to the general efficiency of Linux over Windows I guess.

I did a few benches today.
The SSE 4.1 app is just 1% faster than AVX version on Linux but i talk about 1800 seconds.

The AVX app on Linux takes 180 seconds on the VLAR test task but 315 seconds on windows.
The next few days i will try to get win 7 running and see how this works.

CPU tasks are more than 30 minutes faster than on win.

Is that with the same type of application? i.e. AVX/SSSE4?

It was for me. Same AVX app on the shift from FX-8350 to R7-1700X.
