HD 4000 Collatz

I totally discounted the idea of using the onboard graphics, but Z changed my mind. Unfortunately, I'm having an issue and I'm not sure if it's me or Collatz. I got the drivers updated and set the Intel 4000 as primary in the bios. Got the dummy plug attached. The Event Log is here:

Everything seems good, but I'm getting no Intel wus. Am I missing something or is Collatz out of work for Intel?

I had to completely remove collatz from Boinc Manager and reinstall it. Then, at the website, I set Use Intel GPU to yes. After doing both, Collatz ran fine for me. Cheers :)

It finally started downloading work without further intervention. I'm curious to see it's production. Increased cpu temps 0 degrees c, which I like.

I forgot. WUs didn't download immediately, like with most projects, but an hour or two later. Then, the Intel GPU WUs started coming in. So, delayed start-up seems normal.

Please change your avatar...I always feel like taking a shower when she looks at me. Thanks in advance.

I kind of like looking at her! :P LOL...but whenever my daughter happens to see a page where he posts, she says, Dad, WHO is that? :)) =))

I was looking at Z's times using the HD 4000 on Collatz and I found like wus that were taking me almost 10,000 seconds more to complete. In looking at the wu details I noticed Z's Max Clock to be 1200 where mine is showing a Max Clock 350.

@Z - did you overclock your HD 4000's? Just curious. I see Intel has a Utility to help with overclocking.

Edit: I used the utility to oc to 1250. I'll let it run over night and see how it goes.

My HD 4000 are in my mac mini machines. So maybe the OSX client displays HW differently? Trust me, there is no way to OC a CPU in OSX, much less the GPU inside the CPU. Putting aside the reported clock speeds, I think I may know the problem. I used to have a windows box with HD 4000. It required a full thread to make the GPU load to max out. What does GPU-Z* say about your GPU load? Is it maxed out? Do you have a full thread reserved?

*GPU-Z is the only GPU load monitor that will work with Intel HD, I think.

I have 1 core/thread reserved for each of the 570s and 1 for the HD 4000. GPU-Z (thanks for letting me know that) is showing 94% usage. Maybe I'll just let it get another wu or two under it's belt and we'll revisit it if times don't improve. Thanks again.

Oh! Also, Slicker is working on sending smaller tasks to slower GPUs. All WIP, I think. So maybe your GPU got a "big" task, and had a bigger run time? Be sure to compare c/h and not just h.
