Then I can only run one M2090, unless I get an expansion board, which would allow a total of four cards. That's what I'm actually leaning toward. Just gotta' find a board at a decent price. I saw one listed a few weeks ago for $75. It's gone, and these other guys think their's are made of gold.

Another issue I'm having is finding numbers on these M2090's Are they even worth running? They are DP, which is supposedly a good thing.

I just did some looking, the M2090 has 512 CUDA cores, which is the same amount as a GTX 580.

Yes, It's the same generation. But it's also double precision, which is lots better for some applications, such as BOINC. But I haven't been able to find any real numbers. They are supposed to be decent with Collatz and SETI, but that's all I've been able to find. The post I found was from 2015, which isn't all that old.

I also just discovered that the closest 580 driver to the Tesla driver is 352.79. 352.93 isn't even listed. Not sure what the difference is.

There are only two projects that utilize fp64 instructions.  All of the GPU apps for MilkyWay require double precision for computations.  That is why 7970s and 7990s are still the best bang for your buck on MilkyWay.  The other project that uses fp64 is PrimeGrid.  For PrimeGrid the only application that requires double precision is the Generalized Fermat Prime Search.

 

It looks like the peak fp64 performance for that Tesla is 665 Gflops which is roughly the same as an R9 290X.  That is pretty good, but it is roughly 30% slower than a 7970/280X, which is at 1 Tflop peak fp64.  For all of the other GPU projects the Tesla will probably be right around the same performance as a GTX 580.  I hope you get this sorted out, since I love seeing off-the-wall hardware crunching. :thumb:

 

Once you get those Teslas up and running, you should throw some water blocks on them. :D  Tesla M2090 with EK Universal block

What about a FirePro S10000? I can pick one of those up dirt cheap.tongue.gif
post #298 of 539
Anyone have any opinions of the xeon L5520 CPUs?

I might be able to get hold of a box with a few in. They're a bit out of date, but the price might be right.

Bumping this club as it's been a while since any posts, and I have a curious question.... Which would provide the better overall PPD when attached to two of the Natex E5-2670 bundles.... Four GTX 750 Ti's (two per rig), or two RX 480's (one per rig)? Looking at mainly running Einstein@Home, POEM@Home, PrimeGrid, and SETI@Home for GPU tasks. I'd contemplate four RX 480's but the goal is to keep power consumption below 1000 watts.

.....I'd also be comfortable with having 2x HD 6850 on one rig (since I have a pair of them just sitting there) and then say 2x RX 480's in the other rig...... If projects even support a Barts 6850 anymore that is (and of course, if performance is at least reasonable-ish). I know PrimeGrid does (varies between 0.2 and 0.3x of the best AMD cards) and it seems that SETI@Home will too (it'll be somewhere in between 0.231 and 0.236x as those are the data points for the 6770 and 6900's), but for POEM@Home there isn't enough data (but there is data for the 6900, which is a whopping... 0.089x off of Fiji, ouch).... .....So by the looks of it we're talking around a quarter of the performance of a Fiji card....

Of course all that number crunching makes me look at the 7970 and realize just how much more potent it is in comparison.... 4x more powerful in PrimeGrid on Windows overall, 3.3x more powerful in AMD PPS:SIeve Linux tasks, there is actual data for GFN-21 (0.556-0.642x of a GTX 1080) as well as the 7970 holding the crown for GFN-21:AMD tasks (and is 2.3x more powerful than a 6900 series), and for GFN-22 overall it's as high 0.747x of a GTX 1080 in Linux, and is pretty close in Windows (0.765-0.895x of an R9 Fury series in AMD tasks)..... Which overall would mean that a single 7970 would outperform two 6850's, at least based upon averaged statistics with no knowledge of what speeds those cards are running at, that is.

Then again, the HD 6850's I'd just have to buy waterblocks for and they could go in, compared to the 7970's where I'd have to source a pair as well as the waterblocks.... But on the flipside, the 4xE5-2670's, 2xHD 6850's, and 2x RX 480's is already putting me 140 watts of power consumption over my ideal limit of 1000 watts (assuming 300 watts per E5-2670 setup, although by the results some have posted earlier in this thread I should be budgeting 350 watts each, which makes me 240 watts over my target)...... Hmmmm, if I went with 2xHD 6850's and 2x750Ti's I'm only 60 watts over my goal, but then there aren't any sexy Watercool waterblocks for the 750 Ti's... Of course, another option is just going with 4x750 Ti's and then using Watercool's universal waterblocks - they aren't as pretty as full fledged blocks, and they don't cool the memory, but at the same time it would put me below my target wattage pulled from the wall...

...Or I could just be "sensible" and go with just one RX 480 per rig and have the different clients duke it out for who gets the cards, since there are four projects I want to run, and would be split two per rig.... Or I suppose there's the "downclock the cards slightly" solution, run two per rig, and then keep an eye on power consumption since there are other devices on that same 15A circuit (HTPC, hubby's gaming laptop, my benching rig (obviously would have BOINC disabled when benching), and there will also be a soldering iron on there at some point (to do mods for benching with). Decisions, decisions.

I can't speak to everything, but at FAH a 750ti is worth from 60 - 80k PPD depending on work unit, I have a shinny new RX 470 that got 242k on the first WU I did, we will see how it fairs in the Foldathon.  I have a 750ti and 470 in the same Windows 10 rig, once the Foldathon is over I can run a few work units of the projects you are interested in.
