GPU upgrade question... I was thinking about upgrading from my 1060 6gb at the end of the year and was wondering about some of the newer Nvidia cards. How many work units would a 1660Ti handle at one time? 3 or 4?

It's not a question of how many WUs a card can handle, it's a question of how many WUs per hour can it process.

Hi Grant,

And to think that I still have some of those tapes without a machine to play them in. lol :)

Have a great day! :)

Greetings,

My laptop has... I think 5 WUs left to crunch. I have seen 2 WUs now, that were rated at 5hr and about 20min run time, running in excess of 12 hours. Is there a reason for this happening or have I found something wrong? Most others have run in just over 5 hours.

Have a great day! :)

Siran

[edit]
I checked and the first >12 hour WU has already been removed. One WU took just under 4 hours and the rest, just under 5. The current one should be done momentarily. I'll check it when it has been reported.
[/edit]

[edit2]
14+ hours for the newest listed WU.

Out of curiosity what brand of RTX card would you choose will also be used for gaming

For myself, if I had the extra dough, I would buy the 2060 Super.

Out of curiosity what brand of RTX card would you choose will also be used for gaming

Brands are much of a muchness; everyone has their own good & bad stories and generally sticks with the brand that's given them the least grief.

As for the model, that depends on what games you are playing, and what settings you use.
For many the GTX 1660Ti is as much as they'll ever need. For others, only a RTX 2080Ti is up to the task.
For price, performance & power usage the RX 2060 is a god little card. A very good cruncher, and good enough for most games (unless you want everything set to Ultra settings).

How many gpus can you get into a cpu case that has regular sides on it?
I know there are mining rig cases with regular sides but I am specifically excluding the open sided mining racks.

I have an Intel server MB in an e-ATX case. I am wondering if I can shoehorn 5 gpus in there? ( I am assuming I can find 5 MB slots to put them into which might not be possible. I maybe only have 4 slots).

Two of the prospective gpus are "blowers" so they would be exhausting to the outside. This MIGHT make if slightly cooler in there with the other gpus.

I have to open up the Intel to tinker with a noisy gpu anyway.... so....

I have had similar problems on this laptop. I have had MW tasks take several DAYS, even though the CPU is halfway decent. I changed a few things: Reduced stored work to 0.5 + 0.02 days, disabled crunching iGPU tasks (I had turned it on to see what would happen for a few weeks), and I reduced core/thread usage from all 8 down to 6 or 7. I'm not sure if any one in particular was a smoking gun, but my times seem to be more in line now. I'd like to figure out what specifically caused this, but I don't have enough time and interest to pursue it.

For reference, I asked about this question on the boinc forums and on Milkway.

For reference, I asked about this question on the boinc forums and on Milkway.

I am guessing the reduced "stored work" had nothing to do with any speed up. Running with 90% of available threads aka: 1 or 2 cpu/threads not running Boinc, usually speeds up things.
I have had only 1 counter example where running the Intel internal gpu appeared to speed up a very high end desktop. So in general, running the iGPU from Intel will slow the whole machine down.

If you are using 1 thread/core to drive the discrete gpu then the only other thing you can try is playing with the command line to see if you can speed up the discrete gpu processing any.

Well that was that. I can only shoehorn in 4 gpus without riser cards. The limitation is the spacing of the motherboard pcie slots. So even a bigger case won't help. Just a MB with more space between the slots.

I am still hearing a rattle so I probably am going to have to replace a fan motor.

The good news is after being down for "several" days my Intel server box is running again.

I now have my dinosaur laptop, 13 years old, running SETI. No co-processor, only CPU. We'll see how well it does against my tablet and Pis. :)

Would that happen to be Computer 8747611? If so, I challenge you with MY old laptop, Computer 8513868! Even if your processing power is half of mine, my guess is your RAC will be higher than the Pis

Hi Bill,

Yep, that be the one. It's got a Pentium dual core CPU, 1.73 GHz, 2 GB RAM and Win7 Home Premium 32bit. I believe it has an 80GB HDD.

I got that laptop in 2006 at Best Buy. First time ever buying from them. :)

How old is your laptop? The most I used mine was in 2012 when we had to go to the library to do stuff. That was about a 6 months stretch. Other than that, I hardly used it. Just had it just in case. :)

Have a great day! :)

Siran

It has to be at least 9 years old. My wife had it before we met. I'm sure I can figure out how old it is but I'm too lazy at the moment to figure it out. Its been sitting around collecting dust for several years now so I thought why not let it crunch instead of doing nothing. I installed Ubuntu on it. Hopefully one of these days I'll play around with it more to get familiar with the OS. And if the machine dies out, its not like it was much worse off than when it was sitting on a shelf.

Hi Bill,

I tried to install Linux Mint 32bit on mine and for some reason the laptop refused to take it. I don't remember what had happened, but I decided to put the only "legal" Micro$oft OS I had back on it, Win7 Home Premium. I was NOT gonna put Vista back on it, NO WAY! lol

My laptop finished the cache last night. I got it prepped this morning by swapping the HDD out for a SSD. The SSD is 120GB vs 80 for the HDD. Win7 Pro will be here tomorrow.

I was going to take it apart and seeing about some new thermal paste and do some cleaning, but... Toshiba used Locktite on the case screws and I could not get one of them to break free. I decided not to destroy the head of the screw and put the rest back in. I guess they didn't want anyone getting to the innards of that laptop. Oh well. Perhaps one day I'll just remove the head of that screw with my Dremel and do what I planned on doing today, but not today. There are PLENTY of other screws holding that case together, missing one will not do any harm. I did look at the fan and the vent and they are still pretty dust free from the last time I blew them out.

Have a great day! :)

before I moved to my open rack setup. I was running [7] GPUs all internal like this:



and this wasn't on SETI, but I ran less powerful GPUs in a row of [8] very similarly like this:


If you're using something low power like 1060s, you could cram 8 of them in the same fashion and run SETI. both setups have the lid off for pictures, but I ran them fully closed.

I am pretty sure you used some kind of riser cards/pcie extenders?

I think I remember the pictures. Do you remember the Make/Model?

your criteria listed a case with sides on it. not that they had to be plugged directly to the motherboard. Yes it was using risers. However, GPU specific server cases exist that will take 8-10 GPUs and plug directly into a daughter board with PCIe links back to the main motherboard. ASUS makes one, supermicro has one or several also. they are VERY expensive and VERY loud.

the case I used is a Rosewill L4500 that I modified by removing the HDD cages up front, and moving the center fan wall back further, and used high flow/pressure Noctua fans. this allowed me to fit the GPUs in front of the motherboard and provided enough ventilation to get the hot air out of the case so it didn't accumulate and heat up the GPUs.

if you want all the cards plugged straight into a motherboard. you will have to watercool. and you will have to use GPUs that only has 1-slot I/O, and has a full cover waterblock available. the

In this case I think the most you'd get is 7 on some high end ATX motherboards that have [7x] x16 PCIe slots. and you'd have to find one of those 7x waterblock bridges.

like this: https://www.youtube.com/watch?v=tx52HMRS5Kg

there are also some proprietary server boards with 11 PCIe slots (like my board) that you could do the same, but i imagine it would take a lot of planning and modification. no one makes an 11-GPU bridge either, so i'm not sure how to get water to them all. and as always, be mindful of power to the motherboard. USE GPUs that you KNOW use low power from the motherboard and/or use a motherboard with sufficient auxiliary power for the PCIe slots.

The trick to breaking Loctite loose is to apply heat. That loosens material so that the fastener can then be broken free. You can use a heat gun, hair dryer of for small screws in other material that you don't want to get generally hot with the heat gun applied to the entire product, I use the heat-shrink tip on my butane soldering iron. That allows me to apply pinpoint, localized heat to the screw so that it can be removed without stripping out the head.

I thought Rick said EK dropped the 7x waterblock bridges from their product line. You would have to find one second hand.

Sigh. Its already beyond what I could spend :)

Thank you for the interesting conversation.

And the winner of the "most gpu's in a case with sides" gets a 3D printed "Seti Toaster" (which doesn't get very hot or it will melt).




ROFLing....

Tom

ps. Maybe I should work on a heat resistant "Seti Toaster" decal that I can apply to any toaster or toaster oven?
