I have some questions on 2 of my BOINC rigs.


I built this rig about a year ago:

Asus Z87 A motherboard
Intel i5-4670 CPU, 3.4 GHz o/c'd to 4.1 GHz
Gigabyte GTX 760 GPU, also o/c'd, Nvidia 335.23 drivers
2 sticks of 4 gig ram
Windows 7 Pro 64 bit


I just finished building this rig:

Asus Z87 A motherboard
Intel i7-4770 CPU, 3.5 GHz o/c'd to 4.1 GHz, hyper threading disabled, Could clock higher but have heat problems.
Gigabyte GTX 760 GPU also o/c'd, Nvidia 335.23 drivers
1 stick of 8 gig ram
Windows 7 Ultimate 64 bit


The only projects I run are Optimized SETI and Einstein.
BOINC Manager version is 7.2.42.
Both CPU and GPU are enabled for all w/u.
I do not have a CPU core set aside for GPU use.
4 rigs going through a KVM switch to one keyboard, mouse and monitor.
Monitor is a HP w1907 LCD with VGA and DVI-D inputs (using VGA now due to KVM switch).
I will occasionally game on one of the rigs.
All units run 24/7, CPU and GPU temps average between 50 to 60 deg C.

My first (and possibly only) question is; Is it worthwhile to move the monitor to the integrated GPU and just use the GPU card for BOINC processing?

How much processing power does a monitor really steal?

I understand that I may need to install dummy monitor plugs into the GPU cards and write a Client Config file.
I think I may also need to configure Windows look for 2 monitors.

Would it help to set aside one CPU core for GPU use?
Now, the GPU just grabs what it needs from the CPU core and the w/u processing speed slows down 5 to 10% on that core.

I hope I have supplied enough information.

Thanks for your help!

Poke! Anybody?

Can anyone suggest a better location to post this question?

Thanks, Ron

Probably either the Seti or Einstein forums, or both. I seriously do not know the answer to most of your questions, other than that it's always best to leave one CPU core free to cater for the GPU. Especially with OpenCL apps.
