Can anyone explain this?

This is from twin 660TI's mining jackpot using:

D:\ccminer30\ccminer30.exe -q -s 1 -a jackpot -d 0,1 -o  stratum+tcp://www.hashharder.com:9958

Hashharder reports: 4.2598 Mh/s

What is going on?

I doubt that these two cards are that capable.

I was getting close to 7 MHS earlier

Ccminer35 is for compute 3.5 devices, 780(Ti)
770 is compute 3.0, thats why ccminer30 works

I did set my TDP to 65, but it just doesn't help, there is something else in there that keeps it from performing as expected.

Still pegged at Voltage limits as the reason, but it is a lower percentage of what the top level thinks it should be.

I think it has to do with there being no Pstate 2 (Custom) on the 750ti for whatever reason. Only state 0 and 8.

I am not an expert enough to just go into KBT and start changing numbers with confidence, but that is how I edited the TDP.

Have any thoughts on if the BIOS from one of my MSI cards (TF model) will work on the other (OC model)? Everything reports exactly the same in GPUZ except the model of memory, but I haven't been brave enough to try it. There is a different version on each model, but the TF just runs faster and OC's better.... not sure.

4gb ram? Only with Linux

As for the TDP stuff, I'm curious if it'll be bios unlockable or require a physical voltage mod. I haven't done a physical card mod in ages, I recall modding some old card to over clock it when further as a teen trying to game on a budget, haha.  Definitely good to always consider scalability and future proofing a build if at all possible for sure though. I really like the MSI cards, but I'll see what's available with a 6 pin just in case.

Hey Bigjme, if I recall correctly, you run a 6x 750ti rig.  I'm looking into building one myself (due to the recent spending money JPC and the rise in BTC has made me ).  I have loads of experience building computers and configuring them.  I'm new to the multi GPU route though, never even bothered with SLI for example.  Is there any advice you'd have for someone new to this, and could you recommend a specific motherboard?  Asus, MSI, Gigabyte, ASrock would all be very ideal as I'm in Taiwan and I'll have cheaper prices on those brands.  I'm also pretty in the dark with risers and all.  I've seen some people say they like usb based risers, and then there are powered, non powered, etc.  I know the 750ti doesn't use a dedicated line from the PSU, so that makes me wonder even further if it's wise to run 6 cards through a mobo.  Last but not least, I know that CPU plays into it all a bit.  my current 750ti micro atx has the celeron haswell g1820.  Lovely little cpu, but I'm just wondering if 4gm of ram and a tiny cpu would be enough for a 6 gpu rig.  Of course I'd like to keep it as economical as possible, but I have absolutely no qualms about getting better parts or specs to prevent future issues.  I currently ran into that on the 750ti micro atx rig not preparing for scalability and all.  Thank you in advance!

I can get a GTX 750 2gb EVGA version (NON ti) only difference is this one has 540 cuda cores as opposed to 640

anyone running this card? what type of hash rates are you guys getting on x11 with this or on scrypt?

would love to see a page dedicated to diff versions / hash rates. Maybe a google doc or on cudaminers.cc?

D:\ccminer30\ccminer30.exe -q -s 1 -a jackpot -d 0,1 -o  stratum+tcp://www.hashharder.com:9958 -u -p x

anyone feel free to recommend changes to this bat

Seems to be working. I'll send you some JPC when they start coming in for your efforts.

I'd be interested in your results as I might try something similar over the next few days.

I would be putting a few cards per pool and solo running simultaneously so that difficulty variance doesn't become a factor when comparing results.

Is this how you are doing it? Or are you running all your cards at one pool for x amount of time before trying the next pool/solo?

actually, I am thinking to unlock the tdp.
With the core clock at max overclock, there are clear sign of throttling (the tdp usage ramps up to 118% then go back to 60% and so on... as well as the core clock...)

No problem. I intend to add a lot more configs to help others but ive only had 2 sent to me so far..... hint hint
