I noticed the DDR3. We'll see.

Just for fun. PURELY for fun, I just put a 3450 to work.

I think that's about as slow as we can go. It will be interesting to see what CPUs it nevertheless whips.

I said "purely for fun."

Uh huh.

I found that it wasn't using the GPU. So I goofed around with it a while and found that BOINC couldn't find a usable GPU. So I goofed with it some more, went through additional ATI "driver" fun (WHY do they HIDE the stuff you need?) and regedited and installed and uninstalled and driver-swept and...

Eventually Catalyst 9.7 got it working.

Probably most of that was wasted time and effort. Because, in the end, after a lot of poking around, in an act of desperation I did a fresh reinstall of Lunatics' app and for some reason that I may never understand, it started working.

It also wiped-out all the work units, except for one AP work unit, that had been downloaded. The estimated time to completion was like 93 hours.

256MB of DDR2, and not all of that is available. 40 Stream Processors.

I also notice that there is almost no GPU load.

So, what do you guys think? Should I use the onboard graphics and free-up the remainder of the memory, or should I spend that time at work and then spend $50 on a card with 150% of the clock speed with 440 more Stream Processors and four times as much DDR3 as DDR2 RAM?

Or... do I just forget the whole thing and play with the 6450 when it comes-in?

Isn't that because the HD3450 only works with the hybrid application?

Maybe because you forget to select the proper SSE3 (AMD) app?
Or the CUDA app?

Honestly, I don't think-so, although it might. I installed Brooks+ and I think Raistmer's 555 build may be running it instead of the hybrid. I don't remember all I understood and I understood a fraction of what I was reading.

I'm sorry I don't remember what task was running and that might not clue me into which dll was in use.

I suppose I'll know more 90 hours or so from now.

Well, if I made an error it was in the initial install when I didn't mean to give the CPU anything at all to do.

What I may well have done is chosen an ATI MB application that won't run on this card, so when the driver was able to name the card, BOINC discovered there was no hardware it could use to run the other work.

Things like this happen when you do stuff like this in the middle of the night when you're already tired.

If anyone ever told me I'd fool with ATI drivers to "wind down," I've have told them they were nuts.

BOINC will "see" ATI cards if you have Cat 9.2 or newer drivers installed. That doesn't mean the project you want to run has a working app for that hardware and/or driver version.
You should review the Supported OpenCL Devices list & the Lunatics Readme. Which list what is supported & the driver version requirements.
I spent some time mucking with the drivers to force the HD4000 drivers to load on my HD3850. In the end the result was I couldn't fanagle any OpenCL out of it.
Maybe someone could do some custom F/W for the cards to see if the hardware would do it, but something tells me the effort isn't worth it.
