As seen on the latest energy efficiency test, different motherboards with the same chipsets have different power consumptions.
I'm looking for an am2 motherboard, with a nvidia or amd chipset (opinions about these are appreciated) to use a sempron 3600+ or a athlon64 x2 3800 EE. The purpose: to be used as a server!
So the requirements are:
- Energy efficient!!
- Available at Europe
- cheap if possible
So please post what motherboards you guys have and how much watts it uses at idle and full load (onboard graphics only!).
For the linux users: could you also post the output of:
more /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies (for dual or + cores users)
more /sys/devices/system/cpu/cpufreq/scaling_available_frequencies (for the others)
Thanks for your input!
Off topic: I haven't found any, but anyone seen an AM2 motherboard with a HD24xx series graphics card onboard?
Well, PCKid777, you have system with much more that I want to put in my server, but your results are interesting nonetheless.
For the other posters, I really appreciate your help, but what I'm looking for are real world numbers of the power consumption of this kind of system and know the lowest frequency available in Linux for this platform.
I also didn't know that already exists the gforce 7000 series. I'll have to look about that. Thanks for the tip!
I have the Gigabyte board. I like it. It had no problems with my brisbane chip. The only down side to it would be that I could not get the raid drivers from the disk to work right. I downloaded them and everything went smoothly. I highly recomend the gigabyte!
Although I do like my Biostar, I think I did read somewhere that the 690G is slightly more efficient. Considering that 62 watts at idle is really good, and that's with a 5200+, I'd say go for the 690G.
Good suggestions so far.. The 3200 aka 580x and 480x aka 1150? those are good if you are lookin for OK energy efficiency.. The 690 is better but it has integrated graphics, idk if you want that... Something NOT to get would be Nvidias 590 and 570 (probably lowers ones too) I have a 590 and it's pretty power hungry... They just use more power...
Well, now i can narrow the board specifications a bit:
- amd 690G chipset
- gigabit network
- onboard graphics
I know about Gigabyte's solid capacitors and they also support LinuxBios when the chipset can be supported by it. I had own several cheap Asus motherboards and they are an option also. Other possibilities are Foxconn and maybe Abit. What are your ideas about those? One thing I've learned in the last CPU power efficiency review is that 4 voltage phase is bad idea, in terms of power consumption.
As this pc is going to be used as server (mainly) maybe I would use it also as media center. However don't know if the HDMI is supported in Linux. Any of you guys have used it? Should I spend $10 or $20 more on a board with HDMI?
As a last question, I still haven't decided between the sempron 3600+ and the athlon64 x2 3800+ EE (or the new B2 models). Anyones tested those?
Note that some of these 'processors' are UNDER-CLOCKED versions of faster in-family CPUs.
When all is said and done FOR THE APP ONLY, faster with more cores is more energy efficient, by using fewer Watts x Seconds. From the time you plug your rig into the outlet until the time its shut off is a matter of usage. The more idle time the better EE cpu's look.
I have a Corsair HX520, that would be way more than sufficient for you needs. Anything in the 450W would be plenty, something like a Seasonic S12 430W, or a FSP AX 450W, Silvestone Element Plus 500W, all three would be more than capable to power your system leaving you room if you wanted to upgrade.
I've been searching for some user output about the Biostar board, but I've noticed some complaints that are due to the fact that the board may be in a beta stage. By now it isn't available where I live, so I'll have to wait a bit.
But, one thing I still haven't decided is: should I use an high efficient ATX PSU or should I use an external power brick and a picoPSU?
