Can someone please explain why I'm only getting 1 when everyone else gets 6 ?

It's very frustrating :(

BOINC is probably not requesting any more than that....

I had this using an extremely modified version of XP for benchmarking. Went back and installed my normal XP, worked fine.

btw, I'm not getting 6 wu's/cpu on my quady. I'm averaging just over 2....

2 per core ? That makes 8 available for for your gpus.

I get just 2 :-o

You'll need to tell us more about your system. Which BOINC version are you running? What other projects are you running? What is the resource share for each project? What are the network prefences you have set up?

Thanks mate.

Here's what I've got.

OS Win XP SP3
Catalyst 9.1
Cal version : 1.3.158

E6420 dual core @ 3.4ghz
2gig of RAM
2 x 4830s @ 655/950 run these separately when crunching (Catalyst profile)
Crossfire profile only for gaming (whilst I rarely do anyway).

GPU-Z shows load on both the cards very well.

Detached all boinc projects and the machine is dedicated to Milkyway only...

Boinc manager tried 6.6.36 but slipped back to 6.6.20
Run Always
Network Always avaiable

If I look at the tasks in Boinc Manager I only ever see 2 being worked on ... Never any waiting.

Any ideas would be much appreciated.

Many thanks !

Still need to know what projects you are running and their resource share and also your preferences set under the BOINC Manager menu Advanced -> Preferences then "Connect about every" and "Additional work buffer".

I believe you have a work scheduler issue....so to confirm it I need the above info.

Also thanks for the link to the wu, but it has already been deleted off the system....

Thankyou again for your reply...

Connect about every 10 days .... Additional work buffer 10 days

Maybe my problem resides here ???? Strange really as I haven't changed anything since the last torrent a few months back.

Many thanks in advance :)

WOW !

Thankyou GAS !!!!!! You the man !

Changed connect to 0 and I've got wus galore :)

Many many many thanks.

Someone give him 250,000 credits :)

Glad to see, in the end, it was something simple.

Happy crunching! Now to keep that GPU cool.....

:)

Exactly what I was thinking last night ! You, sure you're not following on Twitter ? ;)

Yep the 4830's cheap cooler does not exhaust the hot air but instead blows it all around the case which in turn messes up the air flow.

Side of the case is off now and the motherboard temp has dropped 6 degrees :-o

Thanks again for your time and patience

Maybe we need to start a thread for the 'best' cooling solutions for single and multiple GPU systems. I also find that the GPU manufacturers haven't really thought about the heat build up in a case caused by their hot chips - but then I suppose they didn't really think that their cards would be used for crunching 24/7!

Totally agree, Gas.

Looking around, even the Musashi and Zalman after market coolers work on the same principle. ie blow onto the GPU with secondary cooling hitting the RAM chips.

Debatable whether this is PCB design flaw ... I'll stop right there !

Probably would be better to discuss this in it's own thread.

120,000 credits later my CPU is at 38C whereas my mobo is at 52C. That in my view is crazy !

Had the WU torrent not stopped a couple of months back - I would have definitely water cooled the cards but I get the feeling that even that would not reduce my mobo temps.

Cheers

I'm a big fan of the big block XFX coolers :) Though I'm also a big fan of cheap GFX cards...
