5775c and a 390x with 32gb ram. i'll eventually get windows on it once i get a ssd for it, but in the mean time for a lil Christmas project. i think a headless Linux box would be neat.



Sorry about the late response... Moved to a farm or what its called.... Getting speedy internet is a task here wink.gif Damn.....


Hi,

Yes of course... We usually just drills holes i a squared piece of plastic/pvc 5mm thick... Use a platform from a case to get you holes right. Then use cobber things for distance wink.gif

However, with prices dropping so fast, you can get a NEW 120G or 60G for dirt cheap. I haven't tried those KingDian (or whatever) drives yet, but am tempted... 60G SSD for $28? Pretty good!

Hi Tex,


SSD's are fast and cheap in energy, but!! I've experienced hardware resets... lost mbr's or what its called. This may just be because of a late night fast reboot. of course I did this myself, but I never had the problem with the optical drives.


What du you think about that??? wink.gif

Hi TicToc,


Thanks... I'll try that... Or I just end the thread with the finished ToDo.. It's about that time I guess wink.gif

Hi,


To end this, I'll post the power differences between the to GPU's GT640 & GTX750ti (Both Low Profile Cards)


Asus GT640:

Volts AC: 220
Amps: 0.96
Watts: 214.5

24H power consumption: 5.2 kW/h

GTX750ti*:

Volts AC: 220
Amps: 1.27
Watts: 281.8

24H power consumption: 6.6 kW/h

* 2x GTX750ti & 2x GTX750

Chrucnhing data using these cards, clearly shows the importance of choosing the right card! GT640 crunches around the half of GTX750ti.. This I'll have to look up, can't remember the exact numbers... But, it's pretty close to double using the GTX750... And looking at the power consumption, it's unreal...
I never thought this rig could run using a 300watts PSU! But look at it... 281.8 watts... It cut's the cost of the PSU down to the half

Well, talking to myself here... Anyway, a nice little thing has appeared (sorry about the danish description.) It's not that higher number of cores, but 100+ still makes a difference. Will it run on a 300watts PSU ??? Its right on the edge I guess
Notice the watts... 75watts, 768 CUDA cores !?!?!?!

Thanks for keeping this thread going.


The 1050 will use a similar amount of power as the 750ti, and perform 40%+ better than the 750ti. I have a 1050ti without external power and it crunches great while sipping power.

Helloooo friends,


OK, I've invested in a wind turbine, a lot of hardware from over there (the states) a solar panel setup and a new card GTX1050ti 4Gb. I'm expanding the project a little. Work has been crazy and I've been totally occupied. I sorry friends.

OK, I'm building this sun and wind power setup. First a 4x 300 watts solar panel config and 1 2kW 48volt A/C 3 phased 40 Amps wind turbine with 2 battery banks. Battery bank 1 is 6x 100A pretty special deep cycle batteries and battery-bank 2 will be lithium-ion 18650 batteries harvested (mostly) from laptop batteries. We will start up with 24 volt banks and then I will go from there to a more efficient 48 volt setup. I've got myself another RACK for this 48 volt battery-bank, but this I will build last. I've bought a 3000watt APC PSU in Belgium, which I will use as a inverter and this will run only on the 48 volt battery bank li-ion. I just got the charge controller last week, from the states as well. a midnite classic 200 which apparently is the best on the market for wind turbines and DIY maniacs like us. It's a pretty nice peace of hardware, that's for sure.

I'll document it all. I'll do videos from start till the end. But I'll write inhere as always, first. This is where it all started for me

The first config will be a Grid-Tie setup, 24 volt battery-banks. A wind turbine needs a load at all times. And of course I've gotten myself som monster resisters (like those we use in elevators for braking) so that when then battery-bank is full, the load is being dump'ed. This dumpload is directed out into these resistors and the overproduction of electricity will be burned of as heat. YES, I know! And of course I've got a plan here. This dumpload will instead be used for running mining rigs, so that the electricity is being used right!

I'm currently running GTX 1050 ti 4Gb on a windows system, testing it for performance mining and temperature. I'm rebuilding "Test system - Beaufort" to run with 4x GTX 750 ti to run on Linux server as a headless rig, as usual.

Actually I'm not very satisfied with the performance of the new card Bitcoin-wise. It's several times faster than GTX 750, but wh are getting nowhere with the bitcoins that way. It's a dollar a day. And yes, free energy - so there's no expenses.


OK, if there's any of you that knows how to install and run e.g. Gminer, T-Rex miner, CCminer on Linux server CLI, I would be so happy for the help. I've used a lot of time figuring all this out and as you know I've succeeded in getting several GPU's running on Linux rigs headless, so the systems are ready for GPU mining.
I know about wallets, I've got one of cause. And one for testing. And I know about pool mining too. I've prepared a wallet for full node mining, and the linux rigs will be full node in the end. That's the goal.

The system I'm building here will begin as a Grid-Tie system. I will build a Off-Grid system too, to have several rigs running there, and then finally, the Grid-Tie'd system, will be rebuild into a Grid-Tie A/C coupled system.

I'm hoping for some help with the mining stuff on Linux.

Here's the status on GTX1050ti running 100% mining the T-Rex GPU Miner v.0.9.2 on CUDA 10

BTW. We will need CUDA 8 on Linux when mining on this card. Maybe there's a new LP card coming soon?

Are we going to use only 1 larger card in the future??? What do you say guys? I've bought some 90 degrees adapters for such a card to be installed on our test systems. But I like the Low Profile GPU's. It's more expensive, I know, but is it better or not? Building a system to compare with shall we?
