Any risers which do PCI Express with more lanes?

Just tried that.  It complained so I just changed it to my standard and am asking the moderator to hide it.

Oh.  It works in every Boinc forum except Einstein.  I guess the server software is out of date.

I didn't get a complaint (not with TWO spaces - one gives an error I've put nothing there), I just got a blank post.

Peter,

They don't sell them anymore.

I don't suppose you want to find yours a good home?

Peter,

I would have to test it to make sure it is working at least for single GPU cards.  I managed to cause one of the those cards to short out.  And I don't remember if it was this one or not.

Then I have to figure out overseas shipping via eBay. 

Tom M

It would be well used here :-)

How did you manage to short it?

I am not saying "a used one" (MB) will be no good.  I am saying I should have bounced a lot more of them back as "not working" than I did.

  A board for my older machine (socket 775) I bought recently, has just decided to slow down to 1/15th speed.  Some kind power problem.  It's getting 12V, but the VRM is outputting 0.25 volts less than the CPU asks for, for some reason this doesn't crash it, but the CPU just runs very very slow.  Unfortunately the simple Intel BIOS has no voltage adjustment, I thought I could compensate by "overvolting" it.  I guess I try another one and resell that as for spares.   The broken ones sell for about the same price as the working ones!

Way back in the Seti@Home days another participant named tBar demonstrated you couldn't get full speed GPU processing on the petri optimized GPU app with an 4c/8t CPU on the first gen lga 1151 MB's.  With a lot of gpus.

Did the CPU or the pci express lanes limit it?

My impression is it was the # of CPU threads available to drive the gpus.  That version of petri's optimized app for Seti@Home would only run one task per GPU.

My understanding on Boinc GPU tasks is there are projects that have tasks that are very sensitive to Pcie bandwidth, Seti@Home and Eienstein@Home are not very sensitive to Pcie bandwidth.

Peter,

I am not sure how I managed to short it.  I can report a scorched card and lightning/smoke.  But I don't believe the card I still have has any scorched spots.

I have a couple of projects this week that will end up with my workbench cleared off.  I will attempt to test that card and see if it qualifies as "used" ASIS rather than "for parts-not working" and take the possible sale to PM.

That's a limitation.  I run more than one if I'm not getting 100% GPU usage.  Although with Einstein I tend to hit the VRAM limit.

Nothing on Boinc has objected to me running 4 Tahitis (4Tflops each) on one PCI-E v2 lane.  Folding at home objects to more than 2 cards.

Unless you managed to connect a 12V power connector backwards, which I did once....  Luckily it shorted against itself and nothing happened.  I had connected it to a live 166 amp rail, and all that happened is one other card on the rail crashed due to a dip in voltage.  When the fans failed to come on, I disconnected it and said oops.  I didn't even burn the wires for some reason, must not have left it connected for long enough.  Yes, 0AWG wire.

Peter, I was wrong. You

Peter,

I was wrong. You can still buy the 1 to 8 card new.

"Sorry, item temporarily

"Sorry, item temporarily unavailable"

What's the model so I can search elsewhere?

When I open the page it says the same thing but if I scroll down with my mouse it shows the part and the model name an number

Model NumberIO1039

Brand Nameh1111z

Item1 to 8 PCIe Miner Machine Graphics Card Extension Card
