Your power draw and temps seem high for a 2600k @ 4.5 Ghz. What are your voltage settings and do you have LLC enabled? I have all settings on auto on the motherboard. I just set 45x multiplier and disabled turbo. CPU-z reports around 1.32 volts during crunching at 4.5 LCC is set to auto as well so I'm not sure if it its utilizing it or not. 200 watts is with the GPU at idle....with 100% GPU load I'm at 230 watts I'm sure having everything on auto has something to do with it. Every chip/mobo combo give different results. I'm running @ 4.5Ghz and use a Coolmaster hyper 212+ for cooling. I pull 180-185w at the wall depending on what project I'm crunching including a monitor. I use manual voltage settings with some of the other settings on auto. I have LLC disabled. My temps are low to mid 60c and will dip into the 50s now that the weather is cooling off. FWIW I would not recommend running 24/7/365 with sustained temps above 75c. JMHO.

This is the old boy which I put together almost 3 years ago but still pumps out approx. 3300 BOINC points/day
----------------------------------------Processor: Core i7-920 at stock speed, undervolted, HT on (8 threads) Cooler: Scythe Mugen MB: Asus P6-T RAM: 6GB Graphics: ATI HD4550 Harddrive: 2 off OS: Win 7 x64 UPS: APC Back-UPS RS 1500VA Power consumption: 149W average measured over a 3 week period (including the UPS). Temperatures: between 40 and 50 degC at a room temperature of 18 and 23 degC. System case has a (very) bad airflow. The undervolt really helped in lowering the power consumption and temperatures.

I have done some digging and I think the temp sensor on my motherboard has an error...When I used to have these same settings I remember temps being in the 60's C. I just felt my cooler and its nearly cool to the touch, just a little warm. There's no way the CPU is 80C if the heatsink is barely warm, right? Unless there bad thermal grease, which I know it has some because I installed it myself. Maybe I'll pick up a tube of arctic silver 5 and re-do it  |

How warm the heatsink is would depend where you touch it, and if it was on and crunching, but a look-warm heatsink and hot CPU could indicate the heatsink is not attached correctly. That said, 80degC for a 2600 @ 4.5GHz isn't too bad.

What type of plug-in gizzmo in the $10 range is used to measure power usage? I'm very interested in using something like that to check power use.
----------------------------------------And where would I find such a device  Advance thanks for any assistance on this.    "Everything in moderation, including moderation" -- Mark Twain |

Thanks for the info. A bit more than the $10 device mentioned above, but still probably a good investment to use on other electricity hogs around the house and workshop. I have a Home Depot about 5 miles away, will have to check this out on my next visit. Again -- thanks for the info. "Everything in moderation, including moderation" -- Mark Twain |

A few more figures.
None of the systems are overclocked. Power consumption is measured with 100% WCG load on all cores/threads; disks are idle but not sleeping; monitor not included. 75 W idle, 107 W load: i3 540, 5 HDD + 1 SSD, integrated graphics 55 W idle when the disks are sleeping. 90 W idle, 225 W load: i7 920, 10 HDD, GeForce 8400 Includes two PCI-E SATA extension cards. Idle keeps jumping between ~60 W and ~140 W every few seconds, the 90 W is an eyeballed average. 55 W idle, 121 W load: i7 2600, 2 HDD + 1 SSD, GeForce 210 45/110 W when skipping the two hard drives and running just the SSD. 88 W idle, 150 W load: i7 2600, 1 HDD + 1 SSD, Radeon 6950 Includes an optical drive and a sound card. Up to ~300 W load with FurMark and Prime95. @Bearcat: Thanks for the figures, sounds like a dual socket system can be quite efficient. |
