I have a EVGA 750 Ti SC 2GB card and did the bios power mod

Can you please share a link to the bios power mod you used?

I just used the msdos nvflash tool from cryptominingblog.com article with kepler bios tweaker tool.  Changed max voltage from 38500 to 65500. Then saved then flashed it with a USB flash drive on boot.

Hello!
I just bought a nvidia gtx 750ti (MSI Twin Frozen) and wanted to use it in an old pc to mine.

The pc has:
CPU: amd sempron 2800+
MB: ASUS K8N-VM
RAM: 1GB (2x512MB)
HD: 160gb
PSU: 400w

It's pretty outdated, but I read cpu isn't important in minig with gpu, and ram shouldn't be a problem either.
The connector is a PCI-E x16 version 1, so less bandwidth than v.3, but I've read it matters in games, not in minig.

The computer is running windows xp atm, latest cudaminer and nvidia drivers shipped with card.

I thought the nvidia could spare me from any upgrade to the computer, and give me some decent hash/sec to start mining.
But I'm not getting even close to the 270kH/s or more reported by other.

I get a max of 73 kH/s constantly, and my pc is running at 100% CPU usage.

What am I doing wrong? Is the cpu the problem? should i change that? or maybe a different os, like linux, would help?

Thanks for your help!

Have you tried running cudaminer with the -H 2 switch? That should get your CPU usage to go down and the GPU should be getting busy!

Arrivata la mia MSI 750 TI 2gb OC TWIN FROZR GAMING   messo a minare subito con cudaminer-MAXWELL-2014-02-18 senza overclock :



Ho lanciato una sola volta CUDAMINER , ma devo lanciarne 2 insieme ? , e cosa devo usare per overcloccarla ?

Utilizzo questa stringa qui cudaminer.exe -o stratumblabla -u blabla - p bla bla    -l T5x24 -i 0

è uscito qualcosa di piu' performante ? Cmq la scheda è silenziosissima e così mi consuma 58 watt

Grazie .

Thank you SO MUCH!
Changing just that switch brought the cpu to 10% and hashrate to 265kH/s.
Could you explain what H=2 does?

Also, I installed just nvidia drivers (+nvidia experience) from the cd I got with the card. Should I install something else that could help in your opinion? Some of the MSI programs?

Thanks again!

Super!

As long as it's working for you, no need to install anything else. You can certainly have some fun with EVGA's PrecisionX or MSI's Afterburner for some overclocking. My own experience is that memory overclocking is where most gains are, easily doing +600 memory clock. Note that with mining, you probably need also to run a custom fan profile, otherwise you might be frying that card soon (or at minimum, getting performance drops due to thermal throttling).

Make sure you try both the x86 and the x64 versions (as long as you have win64 that is...). I'm having better performance on x86 (by about 10kh/s on scrypt), but YMMV. The -H 2 switch moves as much work to the GPU as possible, and relies very little on CPU for mining, thus it gives you the best performance if your bottleneck was the CPU.

Happy mining!
Cheers,

LOL Nice. I guess I should screen cap mine as well. I don't have a cool desktop background though. Just a sea of blue....

Although, do you mind sharing your individual overclock settings?

I'm doing this:

MFG   Device   GPU-Z   GPU+   MEM+
Zotac   1   1   135   125
ASUS   5   2   135   100
Zotac   0   3   100   -100
ASUS   2   4   135   50
ASUS   3   5   90   25
ASUS   4   6   135   100

BUT, I am also using custom BIOS that have the ASUS cards already at MEMCLK+200 and ZOTAC cards at MEMCLK+500. So the MEM+ numbers in the table above are additive to that. e.g. Zotac1 is actually +625.

Point in asking is that my power at the wall is ~625. I suspect I can down clock quite a bit on the GPU CLKs and probably retain within 5 kH/s or 1750 while saving some watts.

I'm using MSi 750Ti Gaming Twin Frozer. Each cards with modded bios (66500mW Powerlimit instead of 38500mW). Each card overclocked to +135/+350. Using ASrock H81 pro btc and non-powered ribbon risers.
Currently my system overall power consumption at 530-540W. Windows 7 x64 SP1 as a system + google chrome trick. Switching to x86 cudaminer allowed me to get extra 30-40 khashes. Currently i'm farming like this:

My 5x 750 ti rig is giving me huge headaches. I'm running all 5 on powered risers and 6 pin connectors on a 750W RM corsair PSU. Asrock h81 btc pro mobo. 8gb RAM. Latest Nvidia drivers.

Is anyone getting huge lag/computer freezes when running multiple 750 Tis (5+) in one instance? I'm running windows 8.1 64 bit, and starting up all 5 at once freezes the PC (sometimes it's huge lag, sometimes I need to reboot, sometimes cudaminer crashes). Seems to only work with regular scrypt without freezing/crashing 100% of the time. I get 250 khs/card mining LTC at stock. I'm about to switch to Windows 7 to see if that changes anything.

If i don't use autotune, TDP usage seems to be pretty low (~850 khs for 5 cards), config: -l T5x24 -C 1 -H 0 -i 0
W/ autotune, I get low 80% TDP. 99% GPU usage.

Also any bit of OC to my cards (EVGA 750 ti ftw) seems to crash cudaminer about 10+ mins later (even "low" ones of +20 core, +200 mem). I don't know how other people seem to get huge clocks with these cards..

Any help would be greatly appreciated. Will throw 10 VTC anyone who can get me up and running stable at ~300+khs/card... Feel free to PM. Thanks!   

Switching to Windows 7 x 64 solved all my problems with lags and 6x750ti scaleability. Have huge lags as well with windows 8.1 x 64. Good luck

Makes perfect sense. Since all load is on gpu I get a little less than I expected (I expected 270-280 or more since the msi is already a bit overclocked).
I have a x86 OS so the x64 version doesn't work for me. Also, I'll gladly sacrifice 10kH for a quieter and cooler pc.
I'll keep it like this for now, it's already a success. The pc is running with just the power cable connected in a corner of my room, very quiet. No monitor or keyboard, and I control it with teamviewer.
The PSU cooler makes a little too much noise, i tried cleaning it but no help :/.

Feel free to ask me any questions.

are you a big fan of side boobs? Applause for sneaking this into my thread.

haha, sorry for this  I tried to hide as much as i could

Hi guys, I have a EVGA 750 Ti SC 2GB card and did the bios power mod and noticed something quite interesting.  I run 24/7 stable with no errors on +25 GPU and +500 MEM using precision x on win 7 x64.

My previous config I was using for my batch file based on reading forum posts was "cudaminer -a scrypt -o server -u user -p pass -l T5x24 -m 1 -C 1 -H 2 and was getting 295-297 kh/s stable. This got me full gpu being utilized and memory on card.

I did some more reading last night and switched to launch config of -l T10x24 and I now get between 310-312 kh/s 24/7 stable with same exact settings.  The craziest thing is that when I check my precision x software it only shows GPU utilization at 540 mhz compared to the full 1344 mhz of the prior launch config.  It's running faster at less GPU load and getting proper accepts!

I think this GPU has more untapped mining potential when we get actual maxwell launch configs and cuda 6 optimizations. Nvidia's mining future is looking brighter and brighter.

I noticed the same thing on mine, but I'm pretty sure it was because I previously had my overclock too high and one of the cards stopped reporting hashes.  I restarted mining and they both started working again at those power usage levels for some reason.  I could have just changed the 10x24 back to 5x24 at the same time, but I don't think I did.  Will have to do testing later. 

I will note that even with the clocks reporting like that, my card still showed 88-95% usage and spikes up to 100 or more at times.  It was a lot smoother running 10x24 on my msi cards without 6pin power though.  It was roughly the same hash as 5x24 I think, maybe a little lower.  The difference was it was more consistent because I don't think it made the card throttle up and down from hitting the limit so much.

Guys suggest anything to mine , i am lost in all these coins now . i like vert but it is not profitable as a multipool. And i hate mooltipools now cause they left me broke with AUR , (cryptsy blocked my withdfraw for 24 hours and i couldn`t sell it on time)

Don't multipools automagically sell your mined coins though?
I thought they pay out in BTC by default?

[liomojo1]

they do , but they ruin cryptos , cause they up the difficulty very fast and everybody drops the coin and the coin dies.

What is the maximum of GTX750 Ti in Maxcoin (keccak SHA3).

Can hit 200 mh/s max overclocked?

My 750Ti can +/- 165 mh with 2014-02-28

[AliMan]

Anyone know any good working launch configs for 780's on Yacoin?

The one in the readme doesn't work, actually nothing with uppercase 'T' works, but rather lowercase 't'.

Hey cbuchner1, how about bout that To Do list  

>>> TODO <<<

Usability Improvements:
- better CUDA error handling and recovery from errors
- add failover support between different pools

EDIT: And no Cudamanager isn't a satisfactory failover implementation.
