Sorry about the delay in replying, I've had trouble with my new machine, as
I've detailed in alt.comp.hardware.overclocking.
No idea what these problems were, hopefully you solved 'em (I gather
from some text below you did).
I could underclock it, yes. I've underclocked machines before. However, then
it would be slower at everything I use it for, which defeats the purpose of
buying this CPU. I could have got a cheaper one that would use less power
and do less work.
It's either this, or try to find out what exactly the BOINC folks had in
mind when they implemented the xx% CPU usage option.
Well, I'm told that Crysis can use four cores. (I'm waiting for the demo to
show on a magazine cover, I can't be bothered downloading 1.8GB.) Yes,
SeiBOINC certainly prefers your CPU to a higher-clocked dual core.
I got the demo the minute it came out (well, minus some download time of
course ;). I haven't really monitored CPU usage during the demo, but it in
any case detects a quad core CPU without any problems. Very impressive
game BTW, the Demo is well worth the 1.9G download.
Understood. I'm not a code-monkey. <g> I couldn't write a script to save
myself. I'm mainly hardware, I can do amazing things with hardware and am
good at trouble-shooting and/or repairing and building PCs. I leave the code
to the guys that know it. I've never been in a situation where it would
benefit me to learn it.
You are now. ;)
I have a couple of "live" CDs and play with them now and then.
And?
I'm still limited, although it's daily, then it re-sets at 2am. After I hit
my limit I'm rate-limited to 64/64kbps, just above dial-up speed until 2am
rolls around. I can "buy" whatever amount of daily data I like by changing
my "plan". Anything from 70MB to 2GB with my ISP. I'm on a 1GB/day plan.
I'm actually dumbfounded ADSL subscriptions are around in this day and
age. Overhere in The Netherlands, you can get a 20Mbps ADSL2+ line for
about 20 EUROs a month. 'No limits' is what they're advertising with,
although underneath is usually some kind of 'fair use' policy.
Your ISP doesn't have an unlimited plan? What speed are you on before
you're rate-limited?
All my experince points to well-cooled CPUs being able to heat up or cool
down at least 10�C a second. Maybe more. The folks on a.c.h.overclocking
agree.
Well, if they say so, it should be true. ;)
[Crysis]
Ah, you have the demo. It was designed to run different things (A.I. etc.)
on different cores (or so I read in an interview with one of the creators).
Yep, very nice. A playable first level, and two benchmarks, one stressing
the GPU (fly-over of the Island), another stressing the CPU (lots of
explosions, buildings blowing up, physics, etc).
Yes, thanks. I'm really happy with it. However, Battle.net server lag still
reduces it to 3 or 4 fps sometimes, especially with my skellimancer. In SP
it's very fast.
Amazingly enough, the Shenk death animation still manages to bring the
8800GTX, using a Glide Wrapper, to it's knees. ;)
I'm a bit curious if/when we'll ever see a GPU capable of running the
Shenk death animation without any hickups. That should be the day!
No problem. Some always needs to be snipped, although I tend to err on the
side of caution.
I snipped liberally. ;)
I'm so happy my new machine is finally running as it should. :-) Got a new
case with a 24cm fan in the side running at around 500rpm. It cools the NB,
SB and RAM quite nicely. There's also a 12cm fan in the front to cool the
HDDs. Lots of vents in the back, a strong breeze blowing through them.
Nice. Enjoy the system, hopefully it can be put to some good use for
SetiBOINC. ;)

Patrick.
