Stress Testing and Power Consumption
Stress Test — Putting It All TogetherAnother test we added to the motherboard suite this time around was the stress test. In this we take all the on-board components and make them all work together just to see if they play nicely.
In our case here this meant running WMP10 on an HD video, having PCMark05 run some hard drive tests, running HDTach on the external USB hard drive, playing a large WAV file and running the network bandwidth test, all at the same time. The tests were looped for an hour and we listened for sound ‘jumps’ or video stutters or anything similar.
The EVGA nForce 680i LT SLI motherboard passed our stability tests without an issue running Ethernet, USB, graphics and hard drive tests all at the same time without slowdown and without crashing.
Power Consumption
In many cases, looking at the power consumption of motherboards and chipsets can seem a little over dramatic. After all, when your GPU eats up a couple hundred watts on its own, whats a few more for a chipset? Regardless, we felt the need to use our power meter to test for power consumption at the wall.
Idle power was taken at the Windows desktop while load results were taken from a dual-threaded CineBench run.
In my experience, the 680i LT SLI chipset doesn’t really use any less power than the 680i SLI chipset, but then again I expected no different. The idle power is a little bit lower on the new EVGA 680i LT motherboard but under a load of the processor, total system power consumption remains the same.
Hi there! This blog post
Hi there! This blog post could not be written any better! Going through this post reminds me of my previous roommate! He always kept talking about this. I am going to send this post to him. Fairly certain he’s going to have a great read. Thank you for sharing! Well also I will share my thoughts on agent sbobet
