Phenom II X6 1055t


Recommended Posts

My old rig ran about 125 watts at idle:

 

ASUS M3A78-T MB • AMD Phenom II X6 1100T 3.3GHz • Mushkin 991762 DDR2 800 (16GB) • 2 x Dell PERC H310 • Seasonic X750 Gold • 12 x Seagate ST4000DM000 4TB 5400rpm (40TB) • 2 x SAMSUNG 850 EVO 1TB SSD (Cache)

 

When I upgraded to Ryzen, it dropped to around 55 watts at idle:

 

ASUS Prime X370-PRO MB • AMD Ryzen 7 1800X 8-Core 3.6GHz • Crucial CT16G4DFD8213 DDR4 2133 (64GB) • 1 x Dell PERC H310 • Seasonic SS-660XP2 660W 80 PLUS PLATINUM • Asus Radeon 6450 1GB (Desktop) Graphics Card • 12 x Seagate ST4000DM000 4TB 5400rpm (40TB) • 2 x SAMSUNG 850 EVO 1TB SSD (Cache)

 

Note that I could run VMs on the Phenom II but it did not support the more advanced features like GPU pass-through.

 

You may be able to better fine-tune the power consumption, and/or electricity may be cheaper where you are than here in Southern California.  I honestly upgraded for VM features, the power consumption difference was a bonus.  Also, I used to have a separate desktop PC in addition to my unRAID server.  Now they both run off the same box, for even greater power savings.

 

Edit: Wattage readings came from the UPS

How did you manage to get such a low idle power consumption? Mine, with a Ryzen 7 1700 - ASRock B450 Pro4 - 32GB RAM - Seasonic Platinum 550W PSU - GTX970 - 11x Seagate ST4000DM000 - 2x Sandisk 500GB Cache SSDs pulls 100W with all HDDs spun down. What am I doing wrong here?

I don't remember doing anything specific.  Probably just running on stock settings.  I don't overclock and I don't game.  I may have chosen the more power efficient profile in the BIOS.  I would guess the GTX970 is pretty power efficient at idle, but then I don't have a lot of experience with those?  It's all I can think of.

And the reading is from your UPS. What UPS are you using? That may be why it isn't directly comparable to others. 

Cyber Power System, Inc. CP1500 AVR UPS.  It is currently reporting 0.090 Kw (or 90 watts) for my Threadripper 1950X system sitting idle with disks spun down.  The Windows 10 and LAMP VM are running, along with Plex (nobody's watching anything).  This is effectively the normal idle for the system.  I don't know why the UPS would report differently from anything else.  How are you measuring your power consumption?  Can you swap out the GTX970 for something else and re-test?

I'm using a Kill-A-Watt like measurement tool. And I've swapped the graphicscard out for a low power alternative and the GTX970 draws arount 10-13 watts. So 100W-13W=87W which is still too much with all disks spun down. I thought it would be around 50W at worst without the graphicscard...

 

The last part I could swap is the motherboard...

Okay, so the Ryzen 1800X is no longer an unRAID box.  That said, I set up my Kill-a-Watt and booted off my spare unRAID thumb drive.  There's nothing configured.  The machine is largely empty, there are no SATA drives nor SATA controllers.  There is one SAMSUNG 960 EVO M.2 1TB NVMe, the Display card is an even older ASUS Radeon HD 4350 EAH4350, and this (normally Desktop) system uses Crucial Ballistix Elite 16GB (2x8GB) DDR4-2666 CL16, which is substantially less RAM.  I have no VMs set up.  So, certainly not apples-to-apples but it's the best I can do under current circumstances.

 

At the wall, once the unRAID boot reaches the login prompt, the Kill-a-Watt reports 43 watts at idle.  So minus the dozen or so spun down SATA drives, an 8-port SATA controller, and less (16GB vs 64GB) memory, the 43 watt total comes in at 75% of the previously reported 55 watts.  That seems pretty fair to me.  At least the readings some reasonably consistent.

 

Comparatively your 87 watts is nearly 40% more than my original 55 watt reading.  I really don't know what could eat up that much more energy.  The 1800X is binned higher than the 1700-series, but again that's a substantial leap in power consumption.  Anything further from here is purely guesswork.  Maybe try another forum and see if you can find someone with a more similar setup to yours and see what they're getting?  You could also try to replicate my recent test (pull power cables or whatever) and see how close to 43 watts you could get?

Thank you for testing! I will configure a second USB drive, pull all the drives and PCIe devices and will test again with BIOS standard setting. If it reports more than 50W somthing has to be wrong. I will then buy a new board off amazon and try with that. Maybe it's a power management issue with the motherboard. That's the last component I can think about.
