Message 15537 - Posted: 15 Mar 2009, 22:18:38 UTC - in response to Message 15481.  

CPU frequency: 2.40003 GHz :-)

BTW: the CPU frequency reported is not correct, according to CPU-Z it is running at 3.249 GHz

I bet you are overclocking with a tool under windows and not through the BIOS.

Actually that is some kind of design flaw of the Windows high performance counters used to measure times with µs resolution. You could add the switch /usepmtimer to the boot.ini to correct that. But in case of the MW apps it is purely cosmetic.

Do you remember the problems some programs had running on an Athlon64 X2 with activated Cool&Quiet when it came out? It was the same Windows flaw causing that. On multi core or multi cpu systems (not with single core/cpu) windows is using for some weird reason the clock of the CPUs as the source for accurate timings and not a clock on the mainboard. Changing the frequency of the CPUs (as with C&Q) changes the timescale for those HighPerformanceCounters. Some programs simply don't like that and run faster or slower than they should (because the time progresses faster or slower for them). I still don't grasp why MS hasn't changed that peculiar behaviour with a simple update in the last 6 years or so.

Message 15538 - Posted: 15 Mar 2009, 22:21:18 UTC - in response to Message 15534.  

Being at 90% the system is more responsive but to be honest I would prefer to have the gpu crunching 100% with 0.19e:)

Sometimes I wonder why I have taken the effort to write a 12kB readme. Is anyone reading it?
If you don't know how to change the behaviour after reading the readme (hint: the f option is what you are looking for), you may ask again ;)

Thanks

You are welcome ;)

Oh yes, I even tried f60 for a while. In fact, I might even try one or two more settings now that you've mentioned it ;)

Does it play nicer with the 9.2 driver or is 9.1 still better? (I couldn't get 8.12 working on my Windows box).

Like the previous versions it should work with Cat 9.2 if you follow the instructions in the readme for copying and renaming some dll files.

I will try that, just for fun. Thanks.

Message 15560 - Posted: 15 Mar 2009, 23:13:17 UTC - in response to Message 15555.  

Your i7 has only one active card. It gets deactivated if the driver does not detect a monitor attached to it.


Bugger!

There goes my plan to place an ATI card in a spare PCI-e slot, without a monitor connected and see it crunch.

I will need to replace the NV card with the HDx8xx series one to make any sense.

You can attach a VGA dummy. If you have some soldering capabilities you can build one on your own for some cents (just three 75 Ohm resistors needed).

That's interesting. Looks easy. I can keep a lookout for that connector (used/cheap). Might come in handy in the future.

It looks very interesting banditwolf.

It implies that several cards, with the right GPUs, could be used to fill the spare PCI-e slots, and these VGA dummy monitor connectors could allow multiple cards to crunch.

I wonder if a couple of the dual GPU cards could be fooled in to having the 4 GPUs available for project crunching?

It wouldn't cost much for a handful of those parts. Worth a shot for someone with those cards.

Yes, assuming the cards were already purchased and the dummy VGA connectors made up in the correct way.

It would clarify whether mixed nVidia and ATI cards could co-exist, as well as whether multi-ATI cards could all crunch together rather than the current wisdom saying that just one card can work. Also, whether that card needs to occupy the primary graphics slot.

Eschewing obfuscation in his thread indeed seems to turn him in to a horrid little man.

If this doesn't get you banned, then nothing will. Let's all crap on each others threads.

The second monitor (or the 1st one again from the VGA via DVI adapter to the second card) worked a treat. Many Thanks :)

No, sorry, I don't have this in any of my existing PCs;

Requirements
Minimum of a 550 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 40 Amps.)

My HD4870 is running with only a 330 Watt PSU, but I have my fingers crossed it won't drain my electricity budget. 550 might just break the bank, let alone my PCs trying to squeeze that PSU in.

Message 15603 - Posted: 16 Mar 2009, 8:21:24 UTC

Hello

i have a problem with the mw 0.19e zslip app, had it with 0.19e too. As you can see in the pic below there are a million 0.19 tasks running. They don't do anything but waiting for the 2 actually done WUs.

My System
core i7 + Ati 4850
BOINC 6.6.15 + SETI AP v5.03 Optimized + MW 0.19e
<avg_ncpus>0.02</avg_ncpus> + <cmdline>f30 n2 w1.2</cmdline>
i tried different <max_ncpus> with no effect
share SETI/MW is 100/100
Cache is at 1 day, sometimes i get a WU that isn't high priority but active anyway.

since i disabled <report_results_immediately> i get much more WUs and so the problem gets worse

Even though the amount of CPU used is really low. BOINC still doesn't use the avg_ncpus properly, so changing it to a very reasonable number like 0.02 means that BOINC goes a little SNAFU. I changed mine to the following:
<avg_ncpus>0.9</avg_ncpus>
<max_ncpus>1</max_ncpus>
<cmdline>n1 f10</cmdline>

Bugger me if I didn't try f60 and the wu came to an almost crawl...comparatively speaking. LOL

with a setting of <avg_ncpus> greater than 0.02 i loose more and more cpus to mw. at 0.03 one cpu idles, i think i had up to 3 idle cpus but don't know the settings anymore.

how many cores do you have?
