The last time I saw anything

The last time I saw anything running on core 5, it still had a really high interrupt number and a really low user number. So I'm considering that core as useless for any real processing.

RE: I meant to add this

I meant to add this info to my last post, but my thumb twitched and it posted without, so here is what else I wanted to pass on.

If it is less than 60 minutes an EDIT will show on your post and you can change what you wrote, or add to it, otherwise you are stuck adding a new post.

Anybody know what the deal is regarding those time values? When a new wu loads, BOINC says it will take x hrs to complete, but after it runs for a bit, that value drops dramatically. For instance, if it says it will take 42 hrs for completion, it actually takes less than 10 by the time it gets done.

This sounds like your Duration Correction Factor is off, you can check to see what yours is by going into Boinc Manager and clicking on the Project tab, selecting a project and then properties and scrolling to the bottom of the page. If it is high you will get what you are seeing, an initial high estimate of how long it will take to finish a unit and then a settling down towards normal as the unit progresses. Over time Boinc WILL fix this itself but it is immediately fixable thru a very careful editing of a particular file. IF you decide to edit the file PLEASE ask for directions, using the wrong file editor or not doing it correctly CAN make things worse!!!

All I gain from allowing 8

All I gain from allowing 8 threads to run flat-out is that my GPU's are then waiting for a share, of CPU time, so the WU's take much longer to complete.

Currently running 4 HT threads on one project, to reduce thermal issues whilst I'm at work. Plus the GPU's keep another two HT threads quite busy on their own.

P.S. Is the O.P.running GPU tasks ? This would explain the extra activity...

I don't know if anybody is

I don't know if anybody is still reading this thread or not, but it's now been a fair amount of time since I installed Process Lasso, and I think it's working out pretty good. I assigned every process I could away from core 5, which according to SIV64, deals a lot with interrupts. I put E@H tasks on cores 1,2,3,4,6,7 and assigned core 0 to the programs I regularly run. My credit averages have gone waaaay up, from an avg of 2000-3000 to an avg now of 6000-7000. I've set personal records of over 9000 in one day, but I figure that's just the luck of the draw. i.e. a bunch of work from one day being reported at the start of a new day

Latency has nearly gone away however in the last day or two, it has been bad. I have to admit though, I highly suspect my ISP because anything to do with the net is slower this past week. I can't get through any video without buffering, but that's another story.

Hey, I'm still waiting for you to lower your CPU voltage ;)

"Hey, I'm still waiting for

"Hey, I'm still waiting for you to lower your CPU voltage ;)"

I figure, why bother? Everything is computing just fine right now. My core temps are under control, even as it gets warmer here.

To save on electricity cost.

To save on electricity cost. And to add some fancy green whatever to your conscience :D

No, seriously.. I try to run all of my rigs at maximum power efficiency for a given speed. That means I'll adjust clock & voltage to a point where there's just some safety margin, going any lower would then result in errors. If the rig is not my personal one I'll opt for larger safety margins, though. But not as large as Intel.

So then do you do any general

So then do you do any general computing on any of those machines, or do they just run BOINC apps and that's it? If their only purpose is BOINC, then I can see the value in doing what you say, but what happens if the machine's utilization curve is up and down like a yo-yo? I'd hate to run into a stall at altitude because then all would come crashing down, no?

Not a single dedicated

Not a single dedicated cruncher. And if they fail under "real world load" I did something wrong ;) (that would probably be "not enough headroom")

On Core 2 class hardware (and older) you'd just set a fixed voltage and be done with it. On a C2Q 6600 I could lower the voltage at stock speed from 1.30 V to about 1.05 V - that was really massive (load power reduced to 65%). On Core i class hardware it does become more tricky, as the more sophisticated power management and turbo modes make everything more complex. Here you typically find an option in the bios called something like "offset mode" for the CPU voltage. Here you set a fixed number to subtract from the original voltage. This is applied anytime, i.e. at idle and in various turbo modes. You couldn't really use Turbo with a fixed voltage, so this makes most sense for an allround machine, which might occasionally be only partly loaded or even idle. You still need to progress in small steps and do so testing, though. Although I have to admit that my testing has become more relaxed in the last years.. but that's only for my own machines, so I know whom to blame if anything goes wrong ;)

I still think he's running

I still think he's running hot and he's gotta redo his thermal paste. Something wasnt cleaned off or secured right up in there.
