Nvidia 750 ti? looks promising
-
They are running like a charm. :D
I’ve a 750 TI and realistic view shows that it gets 250-270 khash/sec in the longer average.
I found the following interesting:
- I even can use my Screen wit very little impact when the cart is mining
- setting ‘interactive’ , the -i switch, on or off didn’t have any impact
- setting GPU_MAX_ALLOC to 100% didn’t have any effect on hashrate, but the autotuning feature
came back with different settings: T14x24 without GPU_MAX_ALLOC and
T20x24 with GPU_MAX_ALLOC= 100%
This means, that the larger available memory is no benefit for the hasrate and in my opinion it also shows, that cudaminer can probably optimized to support these new cards even better.
By the way, my card is taking ~ 60W when mining at 260 khashes. The whole PC is at 140 W then :D
-
Ive just ordered another one (Gigabyte GTX 750 Ti 2GB GDDR5) which means I will still only have three but thats 3X more hashing power than I had last month give or take a few hashes.
I have it in my mind to build a new rig with 4 or 5 of these bad boys.
These seem a little cheaper but have no power cable and only one fan
anyone had any dealings with them?
-
I’m using a Gainward one.
It seems, that all 750 cards don’t have and don’t need an additinal power cable, as they are taking ~ 60 watts and therefore in the specs of PCI-E, which supports one card with 65 watts max
Gainward also has only one fan, but the fans are not that high spinning as with the Radeon.
My card is at 59° C and fan speed is ~ 1000- 1100 rpm only.
It’s hardly hearable, the CPU fan generates more noise.
-
So, a little math here.
Currently I’m running 280x cards. 1 280x draws around 250 watts and hashes stable 700, correct?
3x 750 ti will hash for 750 stable (counting low here) and draws 180 watts, correct?
So the watt / khash is 32,8% better on the 750ti…I’m so selling my 280x before people here in sweden realize this! :P
And with risers I’ll be able to run all cards on one rig even tho I’m running a corsair cx750 psu :P
[edit]
Did a little calc, with current power costs here in sweden I’ll increase the profit with 60ish percent if I run 3 750ti instead of 1 280x :P
-
Yes, that sounds reasonable.
I had one 6950 and one 6790?? running taking the system to 380 W at ~ 650 Khash
As Power is expensive here in Germany, mining was not profitable at all with diffs > 180.
I went down to 260 Khash at 140 W. and could add 3 more 750 to get back to the same power consumption,but would hash at 1 Mhash…
Just my PC doesn’t have the required slots.

I wonder how GeForce Titan Z ($3000 monster) will perform in terms of watts/performance.
There’s expensive PC hardware, and then there’s this: Nvidia just announced the GeForce Titan Z graphics card, a $3,000 monster that essentially slaps together a pair of high-end graphics processing units (GPU) to create something that’s incredibly powerful, but only attainable by a lucky few, Maximum PC reports.
Nvidia CEO Jen-Hsun Huang made the announcement today at the company’s yearly GPU Technology Conference. Powered by a pair of Kepler GPUs, 12GB of RAM, and 5,760 processing cores, it will most likely require some overly elaborate cooling system to prevent it from melting your PC. According to Nvidia, “Unlike traditional dual-GPU cards, Titan Z’s twin GPUs are tuned to run at the same clock speed, and with dynamic power balancing,†which means that neither GPU creates a performance bottleneck.
Though it’s unclear what speed the Titan Z GPUs will run at, the Titan Black, which uses the same Kepler GPU has a rated clock speed of 889Mhz. To give you an idea of what the Titan Z’s performance could be like, the $1,000 Titan Black â€" a beast in its own right â€" has half the RAM and processing cores. Think: Two Titan Black cards, functioning as one.
Instead of focusing on technologies that are on the verge of entering the mainstream, like 4K, Nvidia says the Titan Z is designed with next-generation 5K in mind, along with multi-monitor gaming.
“If you’re in desperate need of a supercomputer that you need to fit under your desk, we have just the card for you,†Huang said. Indeed, if you’re going to build a supercomputer, a Titan Z surely isn’t a bad component to start with, assuming you’ve got the cash for it.
What do you think of the Nvidia GeForce Titan Z? Is $3,000 too much to spend on a graphics card? What’s the most you would spend on one? Sound off in the comments below.
-
It’s Keplar, so I expect it to be juice hungry.
-
I really want to like this card, but I just can’t be f*cked building twice the amount of rigs…

Gotta hope that the rest of the maxwell lineup continues the trend.
-
Anyone heard any more talk about BAMT and Pci-e splitter support?

I’m sure a lot of people will be watching closely, they better hurry up the new ATI range is coming out Q3/Q4… Gonna be a lot of cheap cards on eBay soon…

Okay, so I’ve had my equipment for 4 days now and UGH.
Apparently I’m supposed to be using Windows for these things because of overclocking ability, but I have had ZERO luck trying to get Win7 Ulti on a flash drive, much less using that to install to another flash drive.
I tried using Xubuntu like I always do and it installed fine but then crapped the bed when booting for the first time, an error that streamed down the loading screen that had to do with the problem of NVidia devices in linux and a driver issue.
I’m going to yoink some 20GB satas out of my 360 drives tomorrow and then try to find an optical drive of some sort to do the install.
I hate wasting time like this.

how many nvidia cards does windows 7 support?
-
6 working in cudaminer under win 7:

Didn’t think that’d be my barrier.
-
This may be unrelated but I had issuses as the on board graphics were trying to compete with the cards. If possible turn off onboard graphics b4 boot. I ended up installing Ubuntu 12.04 without any cards installed. Then as you may have read i had to upgrade the kernal b4 the drivers would install.
I’ve not tried windows tho so this all may be useless. :-(
-
No onboard graphics with my Gigabyte 990 tho.

I don’t understand why Windows 7 is so popular for mining, it’s only slightly cheaper than 8.1, people spend thousands on rigs then try to save $20 on software?
Try Windows 8.1, you click windows update, come back in 30 minutes and you’re ready to mine… It really is that simple…
-
I love Windows 8. I’ll admit though, I haven’t used it without ‘Start8’.

I’ve never went after a copy of Win8.
I guess I should? Meh. Can it run off flash drives?

For hassle free mining, it’s got great driver support. All my problems went away when I started using the stock Microsoft drivers that Windows update wanted to install for me.
No mate, you’ll need to grab a HDD, I use a Kingston 60GB SSD in all my rigs and they are fairly cheap…
