Well shit.Now I got my hands on the card, and after a cleaning and a messy cable running session...
Here are the numbers that somehow a few people a waiting for. Saaaaaaadly...
View attachment 320872
The numbers are hovering at 80~100W range. Using latest driver at the time (23.11.1) and quiet BIOS, if that matters.
Without the M27U (the 4K monitor) it will average at ~22W, with lows of 7W if I wait hard enough.
Also, the screenshot function doesn't work perfectly probably because of various monitor scaling / position, but I digress.
Other things I tried that didn't help the situation:
Changing color depths of M27U from 10bpc to 8bpc
Changing resolution of M27U 4K to 1080p (I can guess from the Windows setting screen that signal output is still 4K)
Changing refresh rate of M27U (default 150Hz, tried 144Hz, 60Hz, 59.94Hz)
EDIT: Advanced Power Settings-> PCIE -> Changing from Moderate? to Maximum
Flipping the switch for Eyefinity for the second time (see below)
Things that helped the situation in the wrong way:
Flipping the switch for Eyefinity for the first time
(because of the wacky positioning, of course that's gonna be a horror show. Maybe because I touched some other monitor settings for the monitors, the second time I flipped the switch the power draw stayed high.
The physical space constraint means that I can't put 3 monitors horizontally at the same time. But moar monitors are moar monitors, hence the wacky positioning / config.)
I really didn't think this through huh? What an idiot I am. : /
Now if Windows always remember to turn off the monitors...
( I guess maybe it's the trivial things I run that took away the attention of Windows. )
I swear the SG really isn't 61mm tall after I measured and put both cards next to each other for comparison.
Also, I really hate alcohol beverages (allergy I guess, but also general hate), but I appreciate the thoughts out there...
You're getting the full 3D memory clock there. That's what's pulling those watts.
Yep, card thinks or driver says it just needs to have the full mem clock.You can also try enabling “maximum power savings” for the pci-e under the advanced power settings for the windows power profile.
3 monitors seems to be a tipping point between relatively decent idle usage and basically doubling idle power draw; especially with higher res, refresh, and bpc.
Its really just whether or not the total load you put on the card in 2D is enough to trigger a higher power state. You can intermittently see clock speeds jump up whenever you do something on desktop that's graphically 'something'. Even dragging a window. Most of the time, its too low to move to that higher power state, but if the base resolution output PLUS the refresh rate is high, your base load is already on the edge of where the card thinks it can be for low power states. Also I think its plausible that different monitors on varying refresh rates are going to impact efficiency.That's probably the thing. For decent idle power, you need all of your monitors to be relatively low res and low refresh rate. For example, dropping my 144 Hz display to 60 Hz drops idle power from 36-40 W to about 25.
You can play with this for hours in Adrenalin but all settings approach this from a similar angle; you're trying to limit power usage; , and you can't change the way the card detects the need for higher clocking, apart from perhaps bios edits.
