I have to wonder if the value
)
I have to wonder if the value seen in nvidia-smi isn't a total amount of ram that work unit is asking for but not actually using all of it. I'll have to ask Keith, we talked about it this evening again. He was adamant that Nvidia didn't include more RAM for OpenCl because they prefer to use their CUDA instead. Looking at BoincTask, I don't see that high of a value. I only see 350-435 MB of ram used. But Virtual Ram is over 10GB. So maybe it's storing a lot on the GPUs as it processes and 3200 MB is the size needed? It's hard to know without knowing how the works process. It's late here and I didn't sleep last night. I'll pick Keith brain in the morning.

I think that BoincTasks shows only memory used by the CPU, not what's used on GPU.
Hi Harri, Yes you are

Hi Harri,
Yes you are right. I thought of that this AM once I woke up and had time to think clearly, lol...Funny how one's thoughts are disorganized after 48 hours without sleep.

I didn't think your post was

I didn't think your post was correct either. The only easy place I know of to look at memory usage on the gpu is via nvidia-smi with a watch command or loop timer.
[Edit] Or actually Nvidia X Server Settings app also shows the Used Dedicated Memory value for each card on the main page for each card. But you have to page away and come back for a refreshed value. The page is static unti you change focus and come back.
