yes, my computers are in a warm environment and
even though they are dust free, have 6-8 fans each
and are air cooled with the Noctura 14 my RealTemp
runs about 75 degrees with four cores. 8 threads
pushes the temperature into the mid 80's unless
I cut back on the O/C.
I will start running 6 threads soon and find I lose only about
20% throughput versus 8 threads. The law of diminshing returns
with the HT feature.

p.s....the numbers in previous post are when
all four cores AND GPU are running...just to clear that up.

The GPU always runs a unit in the same amount of time
regarless of the load on the CPU.
I am not sure what you mean about "both processors"
because I have an i7-920 but I am not using HT.
And to add the excitement, while Folding at home uses
less than 10% of a CPU core LLRCUDA uses around 60-70%
of a core.
The GPU always finishes around 5700 seconds.
The CPU's (4) are now taking over 17,000 seconds
for 4 cores/units. Of course, divide by four and it seems/is
the GPU is energy inefficient BUT I could never get
below 12000 seconds/unit running just one Core/unit
(without GPU) so it seems to my brain dead mind
that even though the GPU is a power hog it still beats
One CPU core in a race, even considering the power usage
of the GPU. What am I missing?
I think the GPU might have a better comparison on
REALLY big numbers, like 14 million digits?
Let me know what else you need.
Cheers

Kill-A-Watt says 200 watts with idle mode.

sorry for the delay Carlos....
i7/920 o/c'd to 3.75Ghz
running only 4 CPU's (4 threads)...290 watts 15,000 seconds/unit
running only GTX570 SC ...............360 watts 5,700 seconds/unit
running all 5 above ......................460 watts
Cheers

I agree.
But remember I was running the older drivers, so not
a true test.
LLRCUDA is in it's earliest forms.
Remember that about a year ago people
where saying that LLR would never run on a GPU.
We are still in the earliest code.
My Kill--A-Watt meter says 442 watts
running the GTX and 4 Cores at once.
By the way, final timing was
EVGA GTX570 SC -------5522 seconds.
CPU -----------------------10494 seconds.
CPU running 4 cores ---14792 seconds average
There should be a better result running an SoB unit
which I will try to do.
Cheers.

GTX570 SC (running on 266.xx drivers against instructions)
running 121*2^4207281-1 Time per iteration: 1.303ms.
currently at 40% completion
same # running on one cpu/1thread======>.2.437ms.
i7-920 @ 3.75Gz
the 570 is using about 33% of one cpu
