I have never actually taken the time to do a comparison against 1080Ti before.
My Titan Xp is running these in 83-90 seconds, 1080's around 133s.


Custom water loop with GPU cores running at 35 - 42 C.

Is your Titan air or water?

Interesting

Just wondering what will provide the electricity to power the recharging points.


Slightly off topic but I saw somewhere on the BBC website that some warehouses are now using Hydrogen fuel cell powered drones for stock control purposes, fast refuel times and longer flight time compared with batteries, Hydrogen as a fuel is not dependent on long recharge times, has more power for weight than batteries and can be generated at low power use times, it has also got a fairly low power loss.

Most of the Einstein is done on this machine, 1 card for each and CPU running Seti, I also run Climate Prediction but ATM they are having major server problems. they are CPU only.

The one thing that is annoying, the Threadripper has got a higher RAC over on Einstein than it has here, I run a few WU's to see if or how well it processed them in Linux and set it up to switch over if it runs out of work during maintenance or server failure here. looking at their stats it could easily get into 2nd place on their RAC stats with GPU's only.

Oops, been spotted:-)

I did have a quick play with the settings and found that I could run at 95% processors with no loss on GPU timings, that works out at 26 CPU WU's and 4 GPU WU's.

AP's don't hang around for long, don't seem to be getting many on CPU.

I don't think Petri has much to worry about, he has been processing more than me every time I have looked.

Actually lost a little processing time yesterday, picked up 30 CPU Einstein WU's at 6 hrs each plus about 100 GPU WU's. Burp:-)

Can't let the system get cold:-)

Yes, that was the challenging part, trying to source the supposedly "proprietary" components.


Thats where I was working on a principle of anything that was got working was a bonus and I could scavenge from anything that was considered rubbish.

When buying a to be decomissioned system we would anti-tamper label certain cards - parts to make sure that cards were not swapped out for earlier revision or part faulty cards.

Most manufacturers do not like others working on their gear:-)

OTOH we used to sell back to some of the manufacturers maintenance sections because at times cards were in short supply and they were low down on the pecking order for cards, S/H cards could be used by their maintainers on hired systems.

The quad packages are no fun, so easy to damage the track pads when trying to remove them, the ones that the legs curled underneath them were also a pain. The DIL's are easier but still need a very steady hand.

What I have noticed when handling some of the latest boards though is that the sizes of some of the caps and resistors has shrunk again and some IC's are now using an even closer leg spacing.

I was also seeing a lot of ceramic? sub boards in DIL or SIL through board designs, had to be handled carefully it was easy to de-solder the wrong end of the pin.

Fault finding could be a problem, but luckily I did not have to do too much of that, most of the boards that I was working on were line cards normally 8 or 16 identical circuits on a card, If a circuit went down when a system was in use they just used to transfer that circuit to another circuit or card, when buying old systems you would quite often find several cards with faulty circuits.

A card with a circuit down was worthless, manufacturers would not repair faulty cards they would only sell new ones and they were not cheap, and even technical info about cards was unavailable, even some of the components were unavailable or so they thought:-)

Recovering parts from working circuits on faulty cards I was getting a 50% to 70% success rate at repairing cards, Not bad for an amateur that did not even understand most of the circuitry I was working on.

Most of the work was done with a hot air reworking station, vacuum desoldering iron and a couple of fine temp controlled irons with an assortment of tweezers, knifes and screwdrivers used as pry-bars.

One thing that got me was about this time on the computer side of things the phrase "plug and play" was coming into use, on these phone systems the line cards both phone and exchange line were all hot plugged and had been for ages, you did not need to shut a complete system down to change a card, on some of the larger newer systems that had multiple redundant control systems you could even change a processor card without downing the system.

@ Keith, everything running fine but time is a little short in my schedule so have not had much time to play with Linux.

Rob,

My experience is totally amateur, learned some of the basics when in my teens and still do the occasional basic work when needed.

About 20 years back was working for someone that that was buying and selling 2nd hand telephone equipment, mainly large office type stuff, the systems as well as the phones themselves. In my spare works time I was testing and doing basic repair work and it sort of expanded from there, a lot of the work was basic swapping of components - but down to SMD level, as long as the boss was seeing a return he was happy and willing to invest in any basic tools needed, I ended up leaving when he started to expect too much and he was not quite willing to pay me what it was worth, apart from that he was starting to keep me off the road to much.(truck driver at heart).

I had noticed that things have shrunk even further since then and to be honest I would not like to try to work down to that level.

That does look roomy, I thought mine did until I started putting bits into it.

The mistake I made was to buy everything in one hit when I did not know the sizes of certain parts or the restrictions of the case.

That's why I have got the X71 but have not yet decided exactly how I am going to upgrade this system, position wise I need a fairly thin case.

Re-soldering modern electronics is not easy, was you trying to use a regular iron or a hot air soldering iron and paste?

I was originally looking at Thermaltake The Tower for the Threadripper but too much glass that near the floor with my mutts around, its not unknown for Toby to come charging in with a bone in his mouth:-)

pics!!

Look at the "Whatever One" thread in the GPUUG forum. Details of my build and problems and temporary solutions.


Is it in a private forum or am I looking in the wrong place? Link please.

Getting used to the basics but it may take a while to get fully comfortable with it.

The third option sounds most useful, although I think I will try the first one first.

Both screens run natively at 60 Hz but one uses Display port to use that refresh rate, if I can get it so that I can just plug and unplug and change the resolution without having to restart that will be handy.

The other option is to port it across to the TV but I cannot leave it while unattended like that.(dogs).

Will have a play over weekend.

Hi Keith, I had not found the width setting, it looks a lot better when widened out a bit, I have now got the composite CPU chart and for the time being reduced the number of processor charts to 8, and removed some of the other charts.

How easy is it to switch monitors in the Linux environment, ATM I am running it on a 1920 x 1080 display and using a 3840 x 2160 on this machine, I have got long enough leads to swap them over fairly easily, but for the most part I will want to keep this monitor on the W10 machine.

Temps are looking good, no great change from when running W10, and up-time is now about 2 days, all looking stable.

All looking good.

GKrellm monitor installed, need to play with it a bit, only problem is is there a way to make it display in 2 or columns? I am having to hide most of the processors to see the bottom of the list.

I have switched over to your app_config, had to increase no of processors:-), Have also switched over to the AMD SSE41 cpu app - at first I saw the CPU times increase but after a while they dropped to below previous run times, GPU run times have also dropped, I assume that is the <-nobs> in the app_config working.

Einstein timings have also dropped, 8:20 to 7:30 min, got it stabilised at a low percentage with enough in stock to keep things running if there are server problems.

I've gone the opposite way, I was going to build this system into my old Coolermaster case but when I started to strip it down I decided it was a bit on the small size and ordered up the Thermaltake X71, I got it the same time as the other rad and its still sitting in its box, have not decided yet how I will rebuild this yet but thinking of a simple loop instead of the Corsair H100I which is struggling and proving to be a bit noisy, it also has enough space if I decide to throw blocks on the 1070TI's.

Was a bit disappointed when I looked at my tasks and saw 3 errors, but looking at them it seems that they are faulty WU's, have finished all the WU's in W10 and when I restarted in Ubuntu I managed to generate 2 with "finish file present too long" faults.

With the speed its running I have also attached Einstein and downloaded a few GPU WU's, it will take a little while for the settings in boinc to stabilise.

Bed time know.

Oh so it was not all my fault:-)

Most of my overclocking experience dates back to the time when you moved jumpers on the motherboard.

W10 has has a couple of hrs work left, so I have just switched it over while I go to work, crosses fingers.

Just started getting realistic estimated timings for GPU's.

Now dinner and work.

It was set on the drop down single click option, I did try the Stilts at one time and it failed to post, had to reset via button on back of MB.

Boinc manager CPU usage set at 92% gives 29 WU's, normally 25 CPU + 4 GPU.

In W10 I was getting MB WU's in 90 min and GPT WU in 65 min.

4 x 8 GB 3200 Samsung B die running at 3334 MHz.

I just let it run with the settings that were already set in the download.

My computer software skills are very basic, most of them settings are way above my skills level.
