[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[Hodor_keeper_of_the_light]

Thanks for the advice.

Do you use harddrive or flash memory? How HDD, RAM do you have?

I use cheap 60 gig SSDs as I love SSDs and pretty much despise HDDs but if I were to use linux I'd probably go for usb sticks with kopiemtu or PIMP (if they already have ccminer support, not sure). The rigs don't have any wallets running on them so you really don't need much storage space.

If you're comfortable with customizing windows (7) you'll be fine with 4 GB ram per rig and it's probably more than enough for linux, but otherwise you might want to use 8 gigs.

For motherboards I use Asrock Z77 H81 Pro BTC boards with Pentium G3420 CPUs and single rail 650W power supplies, however I decided not to buy sub 850W PSUs ever again. They are loud, have shorter warranty and look like they have weaker build qulity. Besides 650W PSUs won't be much of a help when/if I replace the 750 Ti's with bigger cards.

Hope it helps.

Sure, thanks

Hello guys
I'm whilling to buy an Nvidia rig. Would you be so kind to give some tips?
Questions are:

What excactly 750ti cards do you recommend? There are few different types of those. What's better to make, 5 or 6 GPU per rig(drivers ok? for AMD at Windows there are drivers for 6 GPU, but there was a time when over 5 GPUs was problematic)?
What OS do you advise? Windows, Linux?

And, if yon don't mind, can you please share your rig configuration? Like, what CPU do you use, power supply, mobo, how much RAM, etc.
Powered risers, not powered?

Thanks

Linux vs Windows is probably more along with what you are comfortable with using.  People are having great results with both.
I have not built a rig specifically for mining as I've just added a couple of GPUs to each of the "servers" I have running around the house.

Those who have done this can give you specifics but here are some of the things I'd suggest making sure to get extra clarification on:
Power Supply with 1 rail vs multiple rails
Quality Motherboad with qty 6 PCI v3 slots
Don't slouch on CPU for nVidia mining. You don't need the latest/greatest but you don't want a low end CPU either for 5/6 cards.
Choice of USB Risers (powered or not) <-- can't help as I'm not currently using them but I'd pay special attention to these to make sure you get the best ones.

I'm looking forward to the feedback you get on this too.

Thanks for the advice.

One tip though, if your going with pcie x1 slots for the card, please make sure they are powered. Even if the cards never use it, it wont draw on it unless it needs too.... better off spending the extra few bucks for the safety of your motherboard and your video card.

For ram I would say no less than 4 gig. I run a few under that does not seem to be any problems though.... the HD can be any size as long as windows fits on it.... heck, I am still using a few old IDE ones I found laying around....even better still I got a few laptop HDs on sale too and use those also....of course they are open air so mounting them is not an issue.

Linux. No HDD, 2 or 4GB RAM.

Yea, I will use powered risers for sure. Some ppl say that performance is better with GPUs plugged right in the mobo, but with 5/6 GPUs it would be problematic, I suppose.

Thanks I've already seen that. But I'm more comfortable using Win.
Happens, there is GPU miner for Linux and everyone's waiting for someone to give compiled GPU miner for Win. But it happens with CPU miners more often(I suppose), and CPU can be mined straight from wallet. I don't know... Sometimes there are wallet/miner only for Win first, sometimes - Linux goes ahead I wanted to put Linux on my new Nvidia rigs, but I haven't decided yet. I would still use Vine or smth(Win simulator). So the point only in going ahead when I've got only Linux miner or smth like that. I don't know tho, will I be able to control whole system(not only simulator) with Teamviewer(I use it for my AMD rigs under Win).

Another dilemma: 60gb ssd and 250gb HDD's prices are the same. So, should I go for SSD?

Also, I run wallets on my rigs during solo, used to be PoS mining only once.

I'm using 1tb HDD's at my AMD rigs, but I found out it's way too big. Also, I have 8gb RAM, I might go for same amount of RAM as well, since it's not big difference in price between 4 and 8.

If you're running separate wallets instead of connecting to a main rig which runs all the wallets, HDD's are more sensible. Although knowing myself I'd still pick SSD's in that case as well.

I recommend you don't cheap out on the power supply. I recently was using a cheaper 500 Watt PSU for a 4 card rig and the main connector for the molex burned up. I was using powered risers at the time. The Machine kept running but the fans stopped. I walked upstairs to a noticeable burning smell. It didnt take long to see why. Now I run 6 card rigs with nothing less than a 850 Watt PSU with a very long warranty. I was lucky it didn't damage the cards.

No problem with Teamviewer under Linux.
And here you can compare Linux vs Windows miner:

I'm trying to mine URO (X11 coin) with my GeForce GTX 780 Ti using ccMiner on Windows 7. I've got a problem with it. The hash rate is great when the ccminer window is active but it drops as soon as I go to another window. GPU activity and temperature drops as well. Any tips on fixing it?

hi

when i see,  on 750ti, 12 mhs myr groestl pour 30-35 w ,
possible to  optimize ccminer to get the max tdp 70W ?
wait for new nvidia drivers?  it they want to optimize them to minage?

you need to mod the firmware (and I can't, my mobo won't let me do it  , and the nvflash doesn't work from windows with the 750ti)

He might be mistaken about making a DOS boot disk to flash from a thumb drive.

My mobo also wont let me boot dos from USB. But when I set to boot from external HD instead of from USB, the mobo detected the flashdisk as external HD and boot the dos anyway. Strange mobo

It was detected, but when I was trying to run nvflash, the computer was just freezing...

I think what he is asking is when will ccminer get optimized to pull closer to its max tdp thereby increasing the hash rate.

If I remember correctly, part of the groestl algo gets pushed onto the cpu, which is why the power consumption on JPC fluctuates.  If this is correct, you'll never see max tdp on myr-grs as its faster to do some of the computing on the cpu.

I stand corrected

30-35w is clearly what they put in the firmware of my gtx750ti (even if it sounds a bit strange...).
Regarding groestl it is fully processed on the gpu not the cpu.

Thanks

I want to share my rig.

Win 7 Home Premium
GIGABYTE GA-990FXA-UD3
AMD Sempron 145 (Mobo and CPU used from AMD rig)
G.SKILL Ripjaws X Series 4GB F3-12800CL9S-4GBXL
6 GIGABYTE GV-N75TOC-2GI
SanDisk 64GB
SeaSonic G Series 550-Watt SSR-550RM
Non-powered riser from http://www.amazon.com/gp/product/B008BZBGPO/ref=oh_details_o00_s00_i01?ie=UTF8&psc=1

In other rig, I use
similar hardware except:
i3 4130
H81 Mobo
SeaSonic Platinum SS-860XP2 (from AMD rig). They are fine for now and I may upgrade the Ram to 8GB later.

hi  this is what i mean

hope 20 mh groestl ,5 mh for x11 .... for 70w power?

don't dream too much though
I think you could gain a few percents may-be... More power means you will have more power to sustain higher core clock without throttling (but obviously there are some limits to what you can put on the core clock).
