does anybody has a quad-core CPU? i'd like to compare filtering speeds when using two filtering threads versus four threads...

I know CSenior has one!!

Stan~ Please go to the following thread and see pics of our CPU's and let me know how you want the tests performed. Like what lottery and package size to use. Also, which filters and how many threads you want operating. I also have a computer stopwatch to take snap shots of speed times which I will post. I was also thinking of setting up a spreadsheet tonight to do the math for just plugging in numbers (calculate speed per thread). Thanks.

try something simple:
- set the thread count to 4
- load a full package
- run e.g. wnh sums filter with any settings and time how long it takes to process it (preview should be enough)
- set the thread count to 2 and repeat the filter with the same settings
- post the times here pls

Lottery = 5/36
Package size = 376992
Thread Count = 4
Filter used = WNH Sums -20/20 setting
Time = 6 seconds

Lottery = 5/36
Package size = 376992
Thread Count = 2
Filter used = WNH Sums -20/20 setting
Time = 9 seconds
=============================================

Lottery = 6/53
Package size = 22957480
Thread Count = 4
Filter used = WNH Sums -20/20 setting
Time = 5 minutes 42 seconds

Lottery = 6/53
Package size = 22957480
Thread Count = 2
Filter used = WNH Sums -20/20 setting
Time = 9 minutes 45 seconds

Please note the CPU clock is 2.4GHz

I hope this helps.

looks like 40% speedup over dual-core CPUs, nice:)

Hi CSenior

Great results. Just a question if you don't mind please. Are you running Vista 32 bit or 64 bit version? Thanks.

I am running Vista 64 bit. You can view my full specs here, just look for the screen shots. I should get better results when I finish OC'ing my CPU to 3.6GHz.

let us know if the overclocking was worth the extra waste heat and noise then:)

Hi CSenior

Thanks for the info. With that cpu and motherboard you should be able to reach your 3Ghz objective with good cooling. 2T timing might be a bit tight with 4 gig ram at that overclock but, maybe ok too. Very nice indeed. Good luck with your progress.

And, while I am at it, many thanks for all your contributions to the forum.

Cheers

Hi Bobijohn,

Thank you!

2T is tight but that is what is recommended by the manufacturer. Right now my machine keeps crashing when I raise the timing to 9-9-9-24 2T @ 1.62V so I have to keep the timing at 7-7-7-20 2T @ 1.50V. I have had the CPU clock stable at 3.2GHz @ 42°C no load. Hopefully, I should reach my objectives soon. It is all about trial and error to see what works best.

Lol Stan,

been OC for 20 years or better...it's always worth it

After long hours of testing and stressing the machine for stability. I have settled on 3.3GHz overclock which has proved to be very stable. At a slightly unstable state I did get an overclock of 3.594GHz which resulted in core temperatures as high as 58°C with full load.

I did not get to test EL at the 3.594GHz overclock but I am now testing at 3.3 GHz The first initial results are below:

Lottery = 6/53
Package size = 22957480
Thread Count = 4
Filter used = WNH Sums -20/20 setting
Time = 4 minutes 6 seconds

The stable overclock shaved 1 minute & 36 seconds from the original time posted in an earlier post.

Great job Stan on adding the threading features to EL!

23m combinations filtered in 4 minutes is pretty slick!:)

Very nice CSenior....are you running on air or water ?
