hi,

we know that Xbase++ Application, since v1.6***, will run on 1 CPU only.

some activeX, like Mappoint, will enable use of all CPUs like 1,3,5,7
on a Intel i7-26030QM / 2670QM with Turbo-boost

now when run a "extrem"**** Xbase++ Application on CPU 1,3,5,7 it will
use Turbo-boost all time ( 100% ) while all together show 20-30%

Problem : after a while CPU "overheat" (?) an complete System stop !
OS() : x64 Home Premium without Network

i want back Xbase++ v1.5 "futures" to run on all CPUs with Intel
"new Generation" i7-2630QM / 2670QM with Turbo-boost

What temperature levels are we talking about?

> an complete System stop !

What leads you to the conclusion that the CPU temperature is the cause of
the system stop?

What are the symptoms? Bluescreen? Core dump?

You should check with a program like prime95 while monitoring CPU
temperature - I'm using the CPU observer gadget from here:

Looks to me as if the CPU has no adequate cooling system in place for such
high loads - especially if it is a laptop.

Try disabling turbo boost (it isn't very useful in most situations anyway):

Hi,

I have seen a system raise to 100% for longer periods of time also. Our
application was run on a terminal server and the database resided on the
file server. The file server CPU went up to 100% when building reports for
example. The cause seemed to be the large amounts of I/O's and waiting for
the responses of the terminal server.

When we put an ADS server at the file server, the problem was solved,
probably because of the buffering of the ADS server. The amount of I/O's
were drasticly lessened.

Maybe it sets you in the right direction. Maybe it has nothing to do with
your case.

Good luck!

hi,

68-74 Celsius

you can hear CPU Fan begin to work ( heatpipe )

> What are the symptoms? Bluescreen? Core dump?

ALL stop and hang ... no CRTL-ALD-DEL ...

thx, this is what i begin now using Speedfan and Co.

it does have a AMD Radeon HD 6650M with 2GB RAM
and work great with lates high-end Games without overheat.

hm ... this is what i do not want to do ...

the new "second Generation" i7 QM with 4 Core (and HT) seems
not to "troggle" (?) like old CPU ... it just switch to another Core ?

but this does not work with Xbase++ "automatic" so i wrote
a Function "switch_CPU()" which i call every time before
load a new HD Video into WMP to find Timecode marker
and make Snapshots for Thumbnails.

IHMO the Problem is that Alaska did not know Turbo-boost
when release Xbase++ v1.6 while it work with v1.5 on "all" CPU

i "think" Alaska have to rewise working with 1 CPU only
with new multicore CPU.

Core I7 CPUs have a max temperature of 100°C, so you should be fine in that
case.

Of course the CPU fan speeds up when the CPU load causes the core
temperature to rise.

IMHO, this is no valid "proof" that the system halt is caused by the CPU
temp... at least in the common meaning of the word "proof".

too bad... that does not help.

Why - if it solves the problem?

Don't know what you mean...

hi,

wow ... i have read it now @Intel website

i agree that, in normal case, a modern CPU will not "die" on heat.
it does run with some never games where  i get high temperature but
still work fine

as i say i have change my code now to switch CPU each time

FUNCTION CPU_SWITCH()
LOCAL nCpu  := 0         try to use hyper threading
LOCAL nStep := 0

#IFDEF CPU2
    init once
   IF SP_CPUmax() = 0
      nStep := 0
      DO WHILE .T.
         nCpu = 2 ^ nStep
         IF SmpSetCPU(nCpu) = 0
            EXIT
         ENDIF
         nStep++
      ENDDO
      SP_CPUmax( nStep-1 )
   ENDIF
   
    depend how much core ( and HT )
   
   IF SP_CPUmax() = 1     1 x  core with HT ... run on HT
      SmpSetCPU(1)
   ELSE
      DO WHILE .T.
         nStep := RandomInt( 1,SP_CPUmax() )
         IF SP_CPUmax() > 1 .AND. nStep = 1  multicore do not use 1st Core 
HT
            SLEEP(0.1)
            LOOP
         ENDIF

         IF SP_CPUactive() = nStep     same CPU ... again
         ELSE
            nCpu = 2 ^ nStep
            SmpSetCPU( nCpu )
            SP_CPUactive(nStep)
          Msgbox("CPU running on "+LTRIM(STR(nStep)),"switch CPU")
            EXIT
         ENDIF
      ENDDO
   ENDIF
#ENDIF
RETURN SP_CPUactive()

FUNCTION SmpGetCPU()
LOCAL i
   i := DllCall("Xpprt1.dll",DLL_CDECL,"_sysGetCPU")
RETURN i

FUNCTION SmpSetCPU(nCpuMask)

   rc := DllCall("Xpprt1.dll",DLL_CDECL,"_sysSetCPU",nCpuMask)

And that actually cures the problem?

Thomas

hi,

sorry for late reply ...

i had to install OS new while that OEM install Version
had all those "Tools" installed where i do not know what
they are doing .... now i get a clean OS

yes, this is what my last picture show. every CPU have a
differnt color and you just see some peaks for a short time.

Tip : if you have more that 1 CPU ( with HT ) try to use
CPU > 1 and not CPU 1 ( Core 0) HT

If you can not run a CPU at 100% without overheat there are thermal 
design problems on that machine. You need a better heatsink/thermal grease.

the i7-2630QM / 2670QM is used with Notebook like
new Ultrabooks. no Chance to change the CPU Cooler

Hi

When you look at the temperature of the micro in the bios, in this point the 
functionalities of the micro are to the maximum

if there the temperature is high, it is possible to say that the problem is 
is the coolers
or in since the chasis it allows the exit of the warm air
