This really strange: GTX1060 and 460 together
 

Shortly after I built this system, I decided that running a GTX 580 was getting really tiresome. I looked at the current lineup, and the GTX 1060 really jumped out on price vs production. It is way cheaper than its larger cousins, and is supposed to use less that half of what the 580 sucks down. It also produces substantially more mfaktc G-d/d than the old fire breather.

All that came to pass, with great results, except for one thing. I want to keep running my venerable Gigabyte GTX 460. After some puzzling and testing, I have found that when the Gigabyte 1060 is in residence, the voltage control for the 460 no longer works, in either Afterburner or the Gigabyte competing program. Take out the 1060, and control returns. Worse, at least in Afterburner, saved settings don't carry over when the hardware config changes. So, no getting the 460 set up solo, then plugging in the 1060.

This all means that I can run the 460 at738 MHz, max. ('Stock' OC is 715 MHz.) Under the old regime, I could crank the card to the upper 800 MHz range, for mfaktc. With CUDALucas, I held that to no more than 848 MHz, with more voltage than mfaktc at the same speed, and the VRAM clocked 200 MHz under stock.

I can live with this, but it is an odd hardware interaction.

GeForce® GTX 1060 WINDFORCE OC 6G
 

This GPU surpasses my fondest expectations.

Example: Gigabytes clock specs:
[CODE]Boost: 1797MHz/ Base: 1582MHz in OC Mode
Boost: 1771MHz/ Base: 1556MHz in Gaming Mode[/CODE]I have not altered any settings on the card. Out-of-the-box, it has run mfaktc at 1860 MHz, giving a steady state output of 570 G-D/D. When it starts, it turns out ~595 G-D/D, which decreases over the first few minutes. I have not been able to tune out the decrease with ini tweaks.

Also, in the context of my fan-loaded case, it is nearly inaudible. If I set the fan to 25% in Afterburner, and then run it up to 100%, I hear a slight change in the tone of the overall noise. It never gets close to 100% in everyday use. It is currently at 68%, and the case fans completely cover it. It is running at 70 C, which is a little higher than usual. The apartment is fairly warm at the moment. In cooler conditions it runs 2-3 C cooler.

Kil-a-watt shows that starting mfaktc on the 1060 increases consumption by about 120 W. The GTX 460 shows 140 W on the same test, producing 215 G-D/D2. That is 17% more power for 38% of the output.

Could you post GPU-Z pictures of the first two tabs?

Our reference model runs quite a bit slower and hotter, but we do not have control over any of the parameters. (We could, but we are trying to keep things simple.)

We wish there was a simple fan-speed-only utility. That is all we would change.

[QUOTE=kladner;453961]I have not been able to tune out the decrease with ini tweaks.[/QUOTE]We suspect that the decrease is due to the card warming up. Ours does the same thing.

Here you go!
Correction:
[QUOTE]I have not altered any settings on the card.[/QUOTE]Its fans are under Afterburner control. Return it to its own control, and the fans drop from 70% to 52%, and then step back up to 60% as the temperature rises about one degree C.

Indirectly, yes. I found that turning the Power Limit to the max (116%) brought it back a good way (573 v 593 GD/D) toward the startup number. The Temp limit was set to 83 C, and the card never went over 74 C. I turned the limit down to 82 just for good measure.

See if the Nvidia procedure on this page helps. I can't check right now, as I am feeding the monitor from the built-in Intel graphics. Wait.....You run Linux, don't you?

Here it is. I don't suppose the same options are available, but it might give you ideas.

OK. This is instructions for Ubuntu/Linux Mint-

This seems to be a productive search area, and I was using DuckDuckGo, not the Goog, which would likely turn up even more.

We gave up and installed the EVGA OC tool.

This is interesting:

Set the card to 50% TDP.

430 GHz-d/day at ~125W for the whole computer, with the display asleep. Plus, low noise and nearly no heat.

Now there's something that had not occurred to me. Instead of adjusting core clock to control temperature, as with older cards, just tell it to throttle sooner. "COOL!" :smile:
