My System Specs

Default Losing time on i7 system

I just built 3 computers for testing purpose. i7 950, 16GB RAM, Asus P7TD Deluxe, Samsung 1TB HDD, Corsair Hydro H70 processercooling + 1 giant + 2 smaller fans in the Antec Performance P193 with Chill Innovation 700W Silent ATX2.3 Modul PWR SUPP. A nice kit in my view

The are now running 16 LabView session 24/7, which is a rather powerful load. Although not more than it can take.

The problem is: It always loses time - about 0.06 secs per minute while it works. It does not seem to lose time at idle. A normal pc and our virtual servers (VMWARE) win/lose maybe 0,01 to -0.01 max.
I know it may sound ridiculous, but our tests are very sensitive to this specific problem.
I have installed "Sync-It with Atom", that can sync with 1 minut intervals using Stratum 1 NTP servers.

This only corrects the error, it doesn't solve the loss in time.

Is there anything in the BIOS or elsewhere that can be adjusted to make the clock straighten up?

Any ideas?

Lightbulb Think I fixed it


I looks like the solution is to (in BIOS) turn of SpeedStep and set Processor mode to Manual speed. Turbomode =OFF.
Also do not use the ASUS Software for controlling the Processor. As soon as this software is started, the time slips with 0.06 seconds per minut. Otherwise the time is perfect.
I used Sync it with Atom for this test, because it could test accurately with Stratum 1 NTP and further it has a great log function. I used a setting with 1 minute intervals, for quick results.

There is nothing wrong in having this ASUS facilty for speeding up /Overclocking, but they (ASUS) should take care of the clock while it is done.
