I would love to try that but I am running on linux (ubuntu) and so can't easily overclock as far as I know. Unless people know otherwise? 2 x 750 (non ti) give me 4.1-4.2 on X11. Overclocked (see my other post).
planning to replace my 40 280x with 66 Ti's , will save 1/2 of power costs.
With the lastest driver, it's possible I have share the info in this thread : https://bitcointalk.org/index.php?topic=167229.msg7718377#msg7718377YOu can also asking info on the KopiemTu (Linux nvidia mining distro) (link in the previous message)

280 h/s is the maximum for xmr?
Pretty much the highest I can get is 285 using -l 8x60 but I applied the regfix included in the last nvminer package, before that I would get BSOD trying to use those setting.

I don't see much of a difference with ccminer. I am still getting 6.8./6.9 Mhash.
Here is my config: nvminer.exe -d 0,1 -a dmd-gr -o stratum+tcp://dmdpool.digsys.bg:3333 -u user -p pass
Any additional flag that you are using to get 7.8? Or perhaps are you overclocking the card?
I'm in my car right now. When i get home I'll lookup what I used to test hash with. I know it wasn't the same pool you used. I also used stock clock speeds but the 750ti is a higher end Gigabyte OCed card. I will post clock speeds also.

Ironic, however is that I was coming home from a court appearance (don't ask). 3rd appearance and postponed again.

Using pool: stratum+tcp://dmd.minep.it:3367 I get hash rate of 7891 hash Using nvidia inspector I get the following: Current Clock: 1333 Memory: 2700 Driver 340.43 So there you go. Almost 7.9 Kh. Easily over 8K with additional OC.

Slightly off topic......wondering if any of you magicians interested in a bounty for DCRYPT GPU miner.....what do you you tink the worth/merit of doing so is??? And I would love to hear some commentary on the algos viability in general.....GO NVIDIA!!! lol Thanks

I used the latest official release 337.88 I guess I would have to install the beta drivers 340.43 Note aside, would it be useful to add a "Drivers" column to the configuration page of http://cudamining.cc/url/configurations ?

In the latest version of NVminer, with all the combined algos, when I am mining XMR is it suppose to slow the machine down to a crawl?

I think so but tsiv releave a version about a week ago that improve this "side effect". Check the readme file about it.

I've update to the Beta drivers 340.88 and the hash increased slightly. Now getting 7.1 Mh or so but still not the 7.8/7.9 Mh you are getting. I also tried with minep.it pool but as I was expecting it didn't change anything. Any more ideas?

I would love to get this version for Linux OS ! It has this facility also, it is just not enabled by default. Add the argument --bfactor=6 to your starting line. This is then the same as Windows default behaviour. You may lose a little hash, but it also drops power usage.

I have not followed the whole conversation, but I am wondering if one of you is running on risers and the other not?

I have not followed the whole conversation, but I am wondering if one of you is running on risers and the other not? That's an interesting theory. I read somewhere that indeed it could affect the hash rate http://cryptomining-blog.com/1276-first-impressions-from-a-6-card-mining-rig-using-geforce-gtx-750-ti-gpus/I, on my side am using risers. Powered for that matter. The difference it rather significant: ~800/900 Kh I am also using ASUS, not Gigabyte. Perhaps that could also be the reason.

Can anyone send me a link to the latest NVminer sourcecode. (merged)
Seems like the funnel shift is missing in some of the 11 algorithms: (With a ROL compute 5.0 + devices will get a boost)
From Github (ccminer 1.2):
cuda_x11_luffa512.cu:
define TWEAK(a0,a1,a2,a3,j)\ a0 = (a0<<(j))|(a0>>(32-j));\ a1 = (a1<<(j))|(a1>>(32-j));\ a2 = (a2<<(j))|(a2>>(32-j));\ a3 = (a3<<(j))|(a3>>(32-j)); #define MIXWORD(a0,a4)\ a4 ^= a0;\ a0 = (a0<<2) | (a0>>(30));\ a0 ^= a4;\ a4 = (a4<<14) | (a4>>(18));\ a4 ^= a0;\ a0 = (a0<<10) | (a0>>(22));\ a0 ^= a4;\ a4 = (a4<<1) | (a4>>(31));
cuda_x11_cubehash512.cu: #define ROTATEUPWARDS7(a) (((a) << 7) | ((a) >> 25)) #define ROTATEUPWARDS11(a) (((a) << 11) | ((a) >> 21))
etc..
By rewriting these macros shift+shift+or cuda instructions can be replaced with a single rol (3 times faster) (Compute maxwell / 5.0+)
