Hello Aaron.
Thanks for writing all that. I believe I understand, mostly.
It's not a laptop, but a desktop machine. So, no battery. I've only
really
experienced overheat problems with laptops, but you might indeed be
right
about the components. Still, my girlfriend's laptop keeps shutting
down for
precisely this reason. Yes, I understand what you mean about it being
ridiculous to have the computer operating at maximum clock when it
doesn't
need to. I suppose that is the whole point of "throttling". I think
you gave
me a clue as to why, even though I thought I had set the plan back to
"balanced", the speed according to several diagnostics was still hanging
around 3500 to 4100 mhz. I'm still trying to understand exactly how the
power plans function.
I was wondering about the processor state and what exactly I ought to do
with it, if anything. I should probably leave the max at 100%; right
now the
minimum is 5% and, based on what you described, I think this should
be ok.
It's also worth noting that the fans in my PC did need a serious
cleaning.
My builder guy is always asking me to check the temps on my computer
but I
just figured that's the kind of guy he is and never bothered on a
regular
basis. I take it most people usually don't, until their computer starts
acting weird or shutting itself off at high temperatures.
I also realised how much of a drain JAWS + Vocalizer was on my system. I
told him that now that I'm back on Eloquence, the difference is
basically
night and day. This system more than meets the listed requirements
but the
performance hit, now that I can actually see (and hear) the
difference, was
drastic. He doesn't really understand this, but he's never had to use or
bother with a screen-reader himself; I believe he thinks it's a lot more
basic than it actually is.
Cheers and thanks for giving my message some thought.

temperature and JAWS
Hi.
Try putting it back on balanced. You don't have a battery do you?
there's no battery icon? If you do have such an icon, you should be
able to
press space on the icon in the system tray and you'll have a left right
slider you can use to adjust the cpu's power consumption for better
battery,
better performance or best performance.
You would want to see if you're on better performance. If not, selecting
that will make the cpu spend more time clocked up, and be more eager to
clock up to complete tasks, but won't force it to stand right at the max
clock continuously.
Btw, having the cpu stay that hot just cause it's running at max
clock even
if it remains under light load is rather ridiculous. Also, I'd be more
worried about high temps like that in a desktop than I would a laptop.
Desktop components may not handle high temps as handily as a laptop
who's
components are all likely built with higher temps in mind e.g. hdds.
If you don't have a power icon tip you can get it to appear by
plugging in a
UPS that will support opperation with no drivers, it should appear as a
battery and turn the platform role over to mobile.
Lastly, you could experiment with minimum and maximum processor state.
1. open power options windows key+x, then o.
2. tab around to additional power settings link, hit that
3. tab a whole bunch of times to change power settings for the high
performance power plan link, or what ever plan it is that you have now.
Hit space on that.
4. Find the changed advanced power settings for the high performance
power plan button, you may land right on it. Hit space on that.
5. in the resulting dialogue you'll be in a list of power plans, you'll
probably be on the high performanced plan but you can select another if
you want, just remember this doesn't make that plan take affect so you
need select that plan after you finish making adjustments to see what
you did.
6. Tab once, in that long tree view, find processor power management,
hit right arrow on it.
7. You should have minimum processor state and maximum processor state
both in here plus a cooling policy that you could also experiment with
to see if it has any affect, I've never seen the cooling policy actually
mean anything.
8. Right arrow on minimum processor state. You'll be able to up and down
arrow here to apply a base percentage value the cpu will be forced to
step at or above. If you have options for both plugged in and on battery
then you need to down arrow to plugged in before you right arrow of
course.
Notes: 0 percent doesn't actually mean the cpu stops completely, it'll
clock at the minimum possible speed, which for modern intel CPUs at
least is 400mhz and also known as sleep mode, often used for performing
basic tasks while the screen is shut or perhaps even asleep. Other CPUs
won't go below 533, 800 or 994mhz or there abouts. You can mess with
this value to set a minimum slowed speed you're happy with, for instance
you may find that if you do 70 percent your c cpu bottoms out at 2.4ghz
or some such, and runs fairly cool and is still reasonably responsive.
Maximum processor state is also very useful but it won't help your
problem most likely, unless you want to try forcing it to run at 2.4ghz
and not go over or under that for some reason.
Note also that most of the time the percentage won't be followed
exactly, you'll get what ever the closest clock speed will be if the cpu
steps up or down to match it e.g. if the buss speed is 99mhz it'll jump
by 99mhz increments ignoring the setting change if you apply it smaller
than that. Also, turbo boost (intel) or I forgot what AMD calls it,
where the cpu jumps clock speeds way higher than the rated clock speeds
at times, will probably get turned off the instant you lower maximum
processor state below 100 percent even one percentage point, and thus
the rest of the scale is from what ever your base clock speed is and
below that, perhaps.
Hope that's useful.

Hey everyone.
So, I am running an AMD with six processors rated at, apparently,
around
3500 MHZ. My system has 8 GB of Ram and is running Windows 10, 1803,
and
JAWS 18. My preferred voice is the premium Daniel Vocalizer voice. Yes,
these specs are all relevant to the topic.
For some time now, I have noticed a certain tendency of my system to
lag,
or
lock up, for several seconds at a time. This only seems to happen when
JAWS
is running. I'm aware that my choice to use this synth does negatively
affect JAWS response time, even on this reasonably fast system. Anyway,
the
"freezes" seem to affect some programmes more than others, but perhaps
particularly Firefox and MS Office products. Sometimes, alt-tabbing
between
open windows seems rather sluggish.
Well, today I ran a utility from a company called Resplendent Software
called WhySoSlow. It's basically one of dozens of diagnostic software
tools
available, that measures your computer's performance by calculating
various
factors. It measures your CPU speed, memory load, and the
temperature of
your CPUs using the sensors that modern PCs have. The system was
running
at
a cool 20-something celsius. It was also running at less than half its
advertised clockspeed, the programme informed me, and suggested that my
CPUs
were being "throttled" to conserve power.
Now, I'm aware that some of these third party utilities measure
specs in
weird ways, or make strange and not always advisable
recommendations. I've
completely gone off using registry cleaners or any such tools for this
reason. I'm also aware that modern CPUs can "clock up" when the load on
them
becomes particularly intensive, but I don't know how well Windows for
instance actually manages this feature. However, I decided to try a
little
experiment. I remembered fiddling a bit with the power settings in
Windows
10 previously, but not to any great extent - mostly just to prevent my
computer from "going to sleep" when left unattended. In the "power
plan"
settings within power options, I adjusted the power plan from
"balanced",
to
"optimise for performance", to see if it would make a difference.
I then ran WhySoSlow again. My computer is now operating at peak
processor
speed, all of the time. I suppose it's also using a hell of a lot more
power, which might not be a good thing. It's also not "running cool"
anymore. In fact, the CPU temperature has doubled all across the board,
reaching as high as 65 C, according to this programme (even higher
according
to the coretemp utility).
However - JAWS is now behaving much more responsively. I haven't had
any
freezes. Alt-tab cycles between programmes nearly instantaneously, and
Firefox seems much faster.
I don't really have a question for the list. I just thought this was
kind
of
an interesting thing to share, and wondered if anyone else had observed
anything similar. It is a fact that with my current setup I am
normally at
a
speed disadvantage when placed against sighted users. This is, I
believe,
in
part because JAWS is somewhat resource-intensive, especially using this
type
of synthesiser (yes, I have considered switching back to Eloquence).
I'm
not
sure if I ought to keep my setup this way. I don't particularly want a
really high power bill and I don't want my computer to overheat,
though in
theory the automatic cutoffs should engage before anything really bad
happens. I actually think it's nice that Windows includes power saving
features, but not necessarily at the expense of system performance.
