GTX 750 Ti mining - Page 80

post #791 of 1291
Is there any consensus on the best 750 Ti for mining. I previously used the MSI gaming which I like and just about to order another 6 and thought I should ask.

How are the EVGA? other brands?

First, I suggest using those with 6 pin power connectors.

From those, people are complaining about ASUS.
EVGA FTW has very good results from people who are using it (EVGA GTX750 Ti products).

I'm using this one and I'm pretty satisfied with it: Gigabyte GV-N75TOC-2GI.
You can also try this (GV-N75TWF2OC-2GI), but not sure if the extra $$$ it's worth.

FTWs too expensive, giga looks good. Looking at the Palit DualX cards too, fairly cheap @ £115 and come with a very high OC and mem running at 6ghz factory, just not seen anyone using them.

Also is it best to go with a NVidia reference design or aftermarket, from reviews aftermarket ones use significantly more power. Was wonder if this is due to added inefficiency or due to factory overclocks?

I'll post some numbers later, for the 6 pin-less Zotac single fan model.

I think part of the advantage of these gpus is the reduced power consumption which translates into cheaper psu's, but it's kinda pointless if you still have to use molex to 6 pin adapters or get a bigger psu to get some connectors for the cards. tongue.gif

Also, the tdp mod is not something I'd do for a farm setup, I'd just grab the stock cards without a 6 pin connector and mount them on an H81 pro btc+g3220 combo with 8gb of ram and winblows (for now) or mod the bios to get an OC and use linux.

Is there any benefit of 8GB, ive just ordered 4GB stick

Also CPU wise I went for the G1820 as was cheapest?

I think im pretty much set on the Palits StormX DualX cards. Highest factory OC, mem running at 6Ghz factory so no need to OC anymore, plus if OCing from reviews says not affected by NVidia power limiters like other brands. Will see tomorrow as delivery due Friday.

Hope they don't use too much power as kind of defeats the purpose, my 6x MSI Gamings are using 440w at the wall on scrypt so anywhere around that range is fine.

One thing though is i'm kind of cutting the PSU close, ordered a 550w NZXT Hale90 Gold unit as was on special offer for £40, compared to the 760w Platninum for my last rig. Hoping PSu can handle running at 80% load.

Those are pretty compelling numbers for the 750ti on HVC. Im getting a total of 10.5mhs on each of my 280x's pulling a combined 500w from the wall. The miner is very easy on the gpu for sure.

Thanks for the tip on Heavy Coin.
My two 750 Ti are each doing 12-12.5 Mhash/s mining HVC
ccminer v0.5 x86
one worker for each card.
in windows task manager, ccminer priority set to high
Compared to scrypt coin: lower temperature and higher OC and more stable (no invalid).



When setting power limit to 75%, hash rate is 11.5-12 Mhash/s

My ccminer code for each 750 Ti
ccminer35.exe -d 0 -t 1 -a heavy -o stratum+tcp://url.com -u work_name1 -p work_pass1 -v 512

ccminer35.exe -d 1 -t 1 -a heavy -o stratum+tcp://url.com -u work_name2 -p work_pass2 -v 512

Trying to mine HVC on my 750 Ti but the hashrate is all over the place. One second it's 11M, the next it's 2M. GPU usage is constantly jumping up and down.

Are you using 1GH pool?
Are you using ccminer35.exe?

Nope, I'm on heavycoinpool and I've tried both 2.0 and 3.5. Also tried x86 and x64 for both.
