I've received several of the new SANTI tasks and they are all immediately failing. Same error on all of them:

ERROR: file mdioload.cpp line 119: Unable to read binvelfile

I've got the same outcome.

Argh....sorry. It's my fault. We will cancel them.

No worries. At least we caught it early.

I've had 3 SANTI_marsalWTbound2 WUs fail on me with "The simulation has become unstable...":

http://www.gpugrid.net/result.php?resultid=10270066
http://www.gpugrid.net/result.php?resultid=10264759
http://www.gpugrid.net/result.php?resultid=10264562

The first two of these completed successfully on other hosts and because I just added a 750 Ti in my box (beside my 650 Ti), I'm wondering if the failures are expected or my setup has started producing errors.

I had to upgrade the NVidia driver to support the 750Ti and in-box temperatures have risen a few degrees with the addition of the second card. The 750 Ti runs noticeably hotter than the 650 Ti at 70+ vs 60+ C.

Did you use Afterburner or Precision to set a fan profile for the 750Ti?

Can your power supply handle the extra load?

And, since most 750Ti cards don't have an independent power cable: can your motherboard power regulator handle it, too?

I had to upgrade the NVidia driver to support the 750Ti and in-box temperatures have risen a few degrees with the addition of the second card. The 750 Ti runs noticeably hotter than the 650 Ti at 70+ vs 60+ C.

The 750 Ti actually uses much less power than the 650 Ti, about 56 watts on a SDOERR_BARNA2 for example verses about 90 watts for the 650 Ti. So the increase in temperature is just due to the additional heat load of the second card, and the heatsinks may be correspondingly lighter on the 750 Ti. The difference in the airflow, depending on the card slot location, can make a lot of difference too.

I am running two 750 Ti's on the Longs now, with temps of 63 to 65 C. That is with a relatively slow (1000 rpm) 120 mm side fan blowing on them in a cool room though. They are the Asus cards, which have good heatsinks but not the elaborate heat pipes of the higher-power cards and may get up to the 70's in the summer.

Thanks for the interest and responses my fellow crunchers! :)

skgiven, I run on Linux, so sadly no cool tweaking tools for me :(

Richard, yes my PSU can handle the two cards, it's a ~600W unit. My 750Ti does have a power connector, so my motherboard shouldn't be power stressed by it.

Jim, both my cards (the 750Ti and a 650Ti) are ASUS and in fact appear to be using the exact same heatsink. I assume the 750 is a direct upgrade of the 650 and ASUS decided to just bolt the previous model's heatsink on the new model, but I don't think it was a very good decision...

I just transplanted the guts of my cruncher to a new wonderful Corsair Obsidian 550D case, putting a 1000 RPM fan blowing on the cards and the temps, while being definitely lower than with the old case, are quite different for the two cards, with the 750 being 10C hotter than the 650! I admit I didn't expect the 750 to be that hot, especially with its power consumption being about one half of the 650's! Notably, my 750Ti is an OC model, running at 1150MHz, but I honestly don't know how much of a difference that OC does make.

I currently have the 750 on top of the 650, using the x16 slot, as the second PCIE slot my motherboard has runs at x4. I guess swapping the cards (putting the 750 below) will lower the 750's temperature (and of course raise the 650's) and probably bring the two cards' temperatures closer together, which would be a good thing.

Maybe it is the spacing of the slots. I always get motherboads that leave two slots free between the top and bottom cards, but some only leave one, which restricts the air flow. And the side fan location is not always ideal. They usually don't cool the bottom card as well, but you have the opposite problem. I think swapping them is worth a try. But I don't think you will see errors due to those temperatures or that overclock yet; it is more a question of what happens in the summer.

It would be nice to switch this discussion to another thread because the title is as off-topic as it can get :P
