Back folding

Took a break from folding, but decided to come back. Probably going to be on and off, but should have 2 x GTX970's folding 24/7 and my Titan X Pascal when I'm not playing games.

Was thinking on replacing my GTX970's so had a look at costs:





Sources:
Average PPD - GPU PPD Database *Mostly overclocked cards
Prices - Overclockers.co.uk *There are other e-tailers out there who maybe cheaper!
Estimated Power consumption - Tomshardware.co.uk *Searched for stress testing with overclock power consumption and used this one source.
£/KWh - Sust-it.net *UK Tariff Average for September 2016

Notes:
The GTX9xx are highlighted as e-bay was my only source for price and I took a low average from there. (Some insane prices there for outdated cards)
Estimated power is for GPU only, I think, so there might be aditional power for all other components not taken into consideration. (i.e. Yearly Cost could be slightly higher.)

Good to have you back from your short break

Your spreadsheet looks like the ones I produce when toying with a new GPU

 

Just realised GTX1060 comes in 2 flavours. Not only is memory reduced, but number of cores is too.

3Gb - Stream Processors: 1152
6Gb - Stream Processors: 1280

This drops the £/ppd and makes the GTX1070 more favourable, but higher yearly costs than 1060.

 

The vanilla GTX 1070 has a TDP of 140W rather than 180W - that improves things

 

Can you go over the TDP if you overclock?

 

My understanding is yes. Pushing the voltage up can massively increase power consumption and take the over-clocked part over its TDP.

 

Well went for a GTX1070; GeForce GTX 1070 AERO 8G OC 8192MB GDDR5 PCI-Express Graphics Card.

Strange thing is the spec says it runs at Boost Clock: 1721MHz, but nvidia-settings is reporting 1830MHz; 1936MHz max.





Got a question for ya Doc.

I've put this in my Ubuntu Server, but not sure how I go about overclocking 2 cards where one of them is not connected to a monitor.

I tried:

Code:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    Option         "Coolbits" "31" 
    BoardName      "GeForce GTX 1070"
    BusID          "PCI:1:0:0"
EndSection

Section "Device"
    Identifier     "Device1"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    Option         "Coolbits" "31" 
    BoardName      "GeForce GTX 970"
    BusID          "PCI:2:0:0"
EndSection

But that didnt work.

GTX1070 I can change the fan speed, but not the clock
GTX970 I can change nothing.


Cheers.


EDIT: Power consumption not bad for GTX1070 & GTX970. (Also have 15 HDD's in the server )


Needs a bit more cooling. Both cards @ 81°C.

 

Woo Hoo.

Found out how to overclock 2nd or more GPU's in Ubuntu from this site: https://forum.ethereum.org/discussion/7780/gtx1070-linux-installation-and-mining-clue-goodbye-amd-welcome-nvidia-for-miners


My xorg.conf ended up as:

Thankfully this allowed me to put the fan of the GTX970 to 100% and stop the throttling.

Hopefully all good now.

 

Glad you got it working. (I couldn't remember the Coolbits value for accessing two cards with fan control ....)

 

Cheers Doc.

It wasnt coolbits for 2 cards, but working out how to fake a monitor attached so the coolbits work. No monitor, no coolbits.

31 is probably overkill and 12 would suffice.
