Title: 12W CPU - 1055T Undervolted to 1.0V, 4 cores disabled Post by: tacotime on July 27, 2012, 08:49:59 PM Idle wattage: 82W
Load Wattage: 94W with Prime95, small FFTs 1055T in an Asus M5A99X EVO, 4 cores disabled in BIOS, CPU set to 2GHz and 1.0V Measured with a kill-a-watt, going to play with the board voltages later Do I win a prize? :p Title: Re: 12W CPU - 1055T Undervolted to 1.0V, 4 cores disabled Post by: DeathAndTaxes on July 27, 2012, 09:01:34 PM Impressive but the CPU load is still >12W. :) The CPU is contributing to the idle wattage. Maybe 30W-40W total?
What are the rest of system specs. I am curious for guestimating the "rest of system" load.

I am curious for guestimating the "rest of system" load. 2 x 4GB 1.5v 1600MHz DDR3 1 x 7770 1 x Wifi card (PCI) 3 x 2000RPM Yate Loon Fans 1 X Hitachi 320GB hard drive It's probably around 30W total if I had to guess, the dual cores at ~1.4v with the same architecture pull 45W Title: Re: 12W CPU - 1055T Undervolted to 1.0V, 4 cores disabled Post by: 50BTC.com on July 27, 2012, 09:49:35 PM Impressive but the CPU load is still >12W. :) The CPU is contributing to the idle wattage.

This may improve result for another ~ 5W Title: Re: 12W CPU - 1055T Undervolted to 1.0V, 4 cores disabled Post by: tacotime on July 28, 2012, 01:40:29 AM dropped all mobo voltages by 20%, nb and ht by 100%, cpu to 0.9v and 1400mhz. now at 68w idle, mining at 150w versus 165w with no performance hit. Ddr3 is also at 800mhz/1.1v
