GTX 750 Ti mining - Page 96

post #951 of 1291
I assume you managed to install manjaro and restarted presented no gui?

If you can get to a prompt can you do a full update. I think majaro still uses pacman .
Code:
pacman -Syu nvidia

Im running my monitor of the intel video card, i managed to do this by installing the nvidia drivers (nvidia-libgl) and then overwrite with intels. It asked to overwrite the libgl package, press yes.

Ah, I see. The guides I have been following didn't mention installing those packages and mostly talked about the mhwd command for installing the nVidia drivers.

I downloaded the packages with pacman and had them all installed. On reboot I come to Grub again and when selecting the OS the boot messages scroll but they stop at a random point after a few seconds. It's like the display just freezes there.

I think I will hold off on using Linux to mine, until I get that DVI-HDMI cable, because it seems much less of a hassle to do using the iGPU for the monitor. Manjaro's install guide shows a GUI installation and I never saw this, probably because of not using the iGPU.

ricers,

I did get the same error when booting a older usb drive of Arch. Its the nvidia open source drivers they have packaged into the release. I think once your using the intel it will be fine.

got my 6 card EVGA GTX 750Ti (no 6 pin) rig up and running. Getting ~20kh/s more on the x86 version vs the 64bit. All 1x to 16x risers.


Not sure how overclocking on this card works, but I manage to get 1678kh/s
with the following overclock and settings:

+175 MHz = 1267 - 1299
+400 MHz = 3100
Stock voltage (1156mV)

Fastest card gets 292kh/s, slowest gets 278

Not sure that the following setting do, but here they are:
-l T10x16 -C 1 -H 2

Using driver version: 335.23

anyone mine MONACOIN? its hight profit.

How did you go about the bios over clocking? I thought it only allowed power modding...

Have you tried the beta drivers which allow over clocking yet? I am a bit clueless with Linux, but am in the same situation in that I have a media/backup server so just stuck some 750tis in and got a friend to help me with the setup!

Have you tried booting a full linux distro like Ubuntu or manjaro?

I have just recently got into mining, i run a 24/7 server anyway so though i would stick a few 750ti's in there. I run Arch Linux and have been flicking between Execoin, HeavyCoin, GroestlCoin and Vertcoin. Currently groestlcoin atm.

My 3 video cards are EVGA SC Single fan models. All plugged into USB 1-16x powered risers. Using the integrated intel video for my monitor.

I have managed to overclock all 3 to GPU - 1290mhz Mem - 3200(6400) mhz using a modded bios. All seem stable.

Regarding the software, ive not had a single crash and its been mining a week of various coins so from my perspective the software seems very stable. Hats off to cbuchner1 & co for the great work on ccminer and cudaminer.
I have downloaded all the software/wallets from there respective git repositories and compiled ok. Had to do some linking of some libraries to begin with but subsequent compiles have been fine.

Some interesting cli commands for querying your GPU's

Question, Can I mine with 5-6x 750ti's that DO not have a 6-pin connector? or will this cause some sort of power issue from PCI-E slots?

If you use powered risers you should be able to, I wouldn't trust any board though if you're planning on pulling 240W from the board just from video cards though, which is what 6 750 Ti's would take.
