Definitely...not sure how good it'll hash, at least till the cudaminer developer fixes the excessive dependance upon pci-e slot bandwidth whilst mining.
You lose a few kh/s with risers and more when going down from 16x pci-e 3.0 to 8x or 1x. It's pretty noticeable.

I got my z87x-oc new for $159 on eBay.

Also I am gonna run the EVGA SC cards for a while. This blog has gotten some decent results with the slight overclocks on reference boards and one of the things that lead me to buying them, since they are among the cheapest of the different brands. However, I may be limited on Linux.

So I did some testing with the TDP hack on my 2 Zotac ref cards. I get around 322kh/s on first card and 314kh/s on second. +135/+650.

But the temperatures were running at 80'C for both. So I reset the BIOS to original.

Right now, I'm getting about 304 kh/s and 298 kh/s at +135/650. I noticed that the kh/s didn't really increase much from +350 mem clock. I got around 300 and 292 with that.

Anyone getting similar results?

hi,all. im new this forum. from japan.biggrin.gif

i had buy 10 GTX 750Ti s ,and build 4 rigs.(5*Palit stormX,5*Galaxy)

when,i had be building one of rig. what has a high asic quality was compared with the low thing.

look at this


ASIC値 mean ASIC quality form GPU-Z. just same over clocked (core +100 mem+300 and stock voltage)

my GTX750ti's ASIC quality is both 71.0~80.1%. 4 GPUs are higher than 75%.

im farming MONACOIN just now. thank you, sorry for my eng too bad:p

Interesting that Asic quality made a difference...clocks are equal on all cards?

I'm starting to wonder if Gigabyte made different revisions already. I edited the bios to 65w tdp and flashed the card and I can only manage 290 kh/s at +135 core and +350 mem. I can go higher on mem but it makes no difference.

Yep, with oc +135/+350 i got 301 from single card via riser and 1763 from 6 cards via risers

Hi, what mobo are you using? what type of risers do you use?

Just wanted to share my experience with an MSI N750TI TF 2GD5/OC.

I'm using CPU +135 / MEM + 635 with bios mod for power target limit and I am getting around 315-320khash/s

OS is W7 x64, cudaminer is latest x86 version with -m 2 -l T5x24 -i 0 -H 2 and chrome webbrowser is running.

If anyone is able to get higher hashrates please post your settings.

How much watts does 1 MSI N750TI TF 2GD5/OC pull?
