Dunno how to fix this.
This rig.....6407690

Was running one 980 2/per. Everything was fine.
This afternoon, I tossed in a780.
The 980 keeps running OK, but the 780 keeps stopping and restarting tasks saying 'waiting for GPU memory'.

Tossed in a 2nd 780. 980 still keeps working. The first 780 seems to be working. The new 780 does the merry go round thing.

Driver reloaded several times. Clean install, of course.
The SoG command line file is blank right now, but I tried several different ones, basic and more aggressive, with no difference on the problem.
Tried 1/per instead of 2/per. No difference.

Any ideas?
I am about out of things to correct or try.

Meow?

Memory 1.99 GB

It could be a case of the system running in to resource problems, not a problem with the video card itself.
The system has to map the memory of each of the video cards, and even though you're using the 64bit version of XP it is much more limited in it's resource allocations than the more recent OSs.
Can you bump the system RAM up to 4GB just to see if it is a system resource issue?


EDIT- the one time I had the error message you're describing was when trying configuration values too large for my video card.
If you've gone back to the defaults, and only 1 WU at a time, then that makes system resources the most likely culprit IMHO.

Quick Google search turned this up in Milky Way forums.

Seems that version of BOINC had some bugs in it that gave that recurring message

https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=2780

They recommended not leaving task in memory and rebooting the system so that it can get an accurate look as what memory there is for the work units.

Sorry, was all I could find. I know you don't want to upgrade the BOINC version.

Mark you running SIV64X to see how much memory you have free?

Edit 2.. Just saw Grant's post about available RAM. I should have looked there first, lol...

This could be mobo related. There is a 6GB Corsair Dominator triple channel RAM kit installed on that mobo. Something is not right with the RAM.
I'm gonna switch the kit over to the opposite 3 slots and see what happens.

If you have Resource Monitor in your version of Windows (type it into the Search box), it will give you a breakdown of the physical memory. The "Hardware Reserved" is what has bitten me, causing similar error messages, although that was in 32-bit Windows. I had to cut back on the number of concurrent tasks in order to squeak by.

Well, I already figured out that XP 32 bit only supports up to 4GB, so I am trying just 2 sticks in the various sockets.
So far, it is not changing anything.

Is the system now reporting more than 2GB of RAM?
If it is only a 32bit OS, then I would expect trouble with more than 2 cards in there. The more memory they have, the more likely trouble is.

My 32bit Vista system has 4GB of RAM. With my old video card, 3.5GB was available to the system.
With 2 video cards with 2GB each, only 2.8GB is available to the OS. And as Jeff Buck mentioned, for each item of hardware, regardless of it's memory size, a certain amount of Hardware Reserved memory is set aside for each device.

I have another XP 32bit rig with a single 1GB stick.
And it is supporting 3 GPUs.

It won't change anything, much, if you have 2 GB sticks....the RAM has to be fitted in, three at a time with those original Core i CPUs. You may remember that I queried the 2 GB that BOINC was showing a few weeks ago.....I was trying to figure out how you could have 2 GB, with three slots. However, given that Win 32 bit only supports 4 GB, you'd think that with 6 GB fitted, you'd at least see the full 4 GB under Windows. Perhaps a retirement would be in order.
Don't take life too seriously, as you'll never come out of it alive!

Sounding more & more like Mother Board issues.

Yeah, well.......
The board was gifted to me quite some time ago when the owner could not get it to run at all.
I guess I'll just yank the 780s and go back to running the single 980 like it was before.

Meowsigh.

And it is supporting 3 GPUs.
I assume that's the one with the 560s. I don't think those require the same memory mapping as the 7xx and 9xx cards. The rig that I ran into the problem with was very happy running 2 660s and 2 750Tis. However, it was probably running right at the memory limit and as soon as I upgraded one of the 660s to a 960 I started getting the "postponed" messages. Checking Resource Monitor, I found that the 960 required an extra 256MB "Hardware Reserved" chunk of the physical memory. So, I reduced the number of CPU tasks to free up some memory. That worked. After a while, though, I replaced the other 660 with a 750Ti and ran into exactly the same problem, another 256MB of "Hardware Reserved". No way around it that I could find, so I reduced my number of CPU tasks again so that I could keep the GPUs at max.

Well, the rig is back to happy again with it's 1.99GB of RAM and the single 980.
Running 1/per now and GPU usage still shows about 99%.
