Sorry I have installed 2 msi 750ti
how should I write in .bat cudaminer ?
im use now string for 1 750ti and is :
cudaminer.exe -o stratumblabla -u blabla - p bla bla -l T10x24 -i 0
.
This is what i'm using: cudaminer.exe -d 0,1 -i 1 -l T20x20 -o url -u username -p password pause
Gets me 280+ kh/s with chrome opened and a little OC.

Is this really needed ? I mean, on windows MSI AB gives already these infos (and some others more important) and on linux there is nv_smi (or something like that) which can give you info about the card temp, fan, clocks speed) As long as it won't be possible to overclock the card from cudaminer (obviously this is the goal), you will still need to have MSI AB opened to be able to overclock the card, so you already see the temps/fan speed etc... so...
edit: Must admit that MSI AB is quite messy when there are several cards on the system
the basic idea is to enable an emergency shutdown and/or a throttling based on temperature so you don't risk your GPU's life because a fan has failed (nVidia drivers are throttling hard at 95 deg C but I've seen my MARS cards get to 100 deg C during testing). Also these values are an important data points to send through a remote monitoring API - without these the monitoring would be next to useless. I have to praise this code submission as mission critical (the mission being able to run massive nVidia mining farms). Christian

Also these values are an important data points to send through a remote monitoring API - without these the monitoring would be next to useless. I have to praise this code submission as mission critical (the mission being able to run massive nVidia mining farms). Christian Hi, I do think that the reporting of the extra GPU monitoring data should be an optional feature so that people that don't want it don't have to read it :-) In regards to internal monitoring vs. external tools like nvidia-smi, I have a few thoughts: For more humble or small-scale purposes, the patch is also useful in that allows in-band monitoring of the GPUs used by cudaminer, without having to collate separate logs from cudaminer and nvidia-smi. At the moment the code I sent Christian only does monitoring of a few GPU attributes. The NVIDIA drivers in some cases also allow application clock rates and other settings to be modified on some types of GPUs, and reporting what is limiting the performance of a GPU, whether it is power, heat, or other factors. My existing patch doesn't do any of these other things yet, but as the capabilities of NVIDIA's NVML library increase, it should be possible to add more of them if people want them. My cudaminer patch uses the same interface that the nvidia-smi utility itself uses (NVML), so potential feature set is similar, except that my cudaminer patch also does one important extra thing: the data reported by my cudaminer patch will exactly match the GPU ID that the hash rates etc are reported for. If you use nvidia-smi, one problem is that it uses a different GPU indexing scheme than CUDA uses, so you would have to sort that out for yourself if you did external monitoring. The issue of the different GPU indexing schemes is most confusing when you have a few identical GPUs where you can't tell them apart by their names. This is one of the things I dealt with in the cudaminer patch that you wouldn't get if you did monitoring with nvidia-smi, and likely other tools. Cheers, John Stone

I would love to see a possibility to throttle the card(s) to reach a temperature/utilization target. nvidia-smi shows the fan-speed and temp but not the "GPU Utilization" as nvidia-settings does...

I must say I didn't think through everything, when I wrote my message. (and my gtx780ti throttle down itself when the temp get higher than what I want which , I forgot about other cards...). Yes it can be very useful.

750Tis on new drivers allowed my overclock to push the cards from 3.3kh/s to 3.5kh/s on Yacoin.

The price hike on Nvidia 750ti is steadily rising.
I went into Fry's this weekend and the 750ti OC went from $154.99 to $169.99 and now it was $199.99. The Asus (I believe gamer edition) was $209.99.
So glad I got mine the day they came out.
The regular 750 (non ti) are still at the price when they came out. $144.99-$149.99. Depending on wich version you get.
Hate to say it but when the 800 series come out, they will either be at MSRP or a few weeks later will be over it.
I'd suggest you get them first chance you get to save some money.

If you are going to leave your BTC on an exchange please send it to this address instead 1GH3ub3UUHbU5qDJW5u3E9jZ96ZEmzaXtG, I will at least use the money better than someone who steals it from the exchange. Thanks

Same thing here, i got mine for €133 the first week they came out and i checked again and it's now €144 - €150.. Saved €20

I think if you can get HeavyCoin to work Christian, then it's going to be a max coin style event. Nvidia as only capable miners, would be another big profit venture if you can get it to work off their cpu code
Are there any exchanges yet for HeavyCoin? Mined 20 coins on my CPU's today but no idea what the value would be? www.atomic-trade.com

I'm mining GPUCoin on p2p pool and getting a lot of boooo's, where as in pool i get almost none with same settings:
cudaminer.exe --algo=scrypt:2048 -d 0,1 -l K8x16,T5x24 -H 2 -C 2
Anything I'm missing? Thanks.
EDIT: Well they just enabled stratum+tcp and it's a lot better now, although still more booo's than on "regular" pool.

It's normal, it is expected that you get a larger fraction than on normal pool. Try to adjust the number behind the adress+0.000something

I did some testing tonight on my 2 750ti , and noticed that only the x64 version needs the chrome trick , x86 have better results about 4-5 kkhs than the x64 -with or without chrome. So x64 needs chrome and x86 no . Sadly my max overclock stable for minig is 1355 core and 3196 mem. Max hashrate with this settings 320. May be when the rizers arrive i will try more cause now heat is an issue too cause both card are stack together and make 77-80 C.

Yes i mod to 65500 power , but now i am back to my 45500 bios where i get 1305-1320 mhz and 315khs. Almost same result with less power.

His hashrate sucks for that high of an overclock. Getting stable 330kh with a +125 +600 overclock.
