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...)
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.

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?
I have just been running the entire rig on different sites for 24 hour periods. If just comparing two sites splitting the cards might work, but I was planning on 4-5 sites plus soloing, so still have to find some way to account for average difficulty over the mining periods with some block research once the data is all in. I am planning on making a nice post on the matter when done if it is still relevant in a week or so. So far just a rough estimate shows that the mining difference between hashharder and miningpoolhub to be very close, in fact hashharder was a bit better payoff, but inconclusive until I get an average difficulty over the period. Solo I ran for two days prior and only hit two blocks (1 of which orphaned), but others actually had better rates, so that could have just been an outlier.

I was just searching for the GeForce GTX 750 based on price. Cheapest around $119/us. Could have swore I saw them for $79/us somewhere.
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? I get: Scrypt 1 EVGA 750 SC = 260-270khs 1 Gigabyte 750Ti = 285-295khs Jackpot (JHA) EVGA 750 SC = 3200khs Gigabyte 750Ti = 3900khs Some algorithms I haven't found much difference and in fact, I think even though the 750 hashes slower than the 750Ti on Jackpot, it finds more blocks. My rigs that have at least 1 750 in them seem to find more blocks than my Ti's. I don't know why and haven't spent much time looking into it, but I've got at least a month of results on a pool to look at and for some reason the 750s have a greater chance of finding them than my Ti's. My 1 750 in an old HP desktop has found almost 40 blocks and my 6x750Ti EVGA FTW rig has just barely found double that.

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 ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) ). 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! https://litecointalk.org/index.php?topic=16578.04gb ram?

Ive had to switch out my 16gb kit for an 8gb kits while i check my memory corruption issue out. And how does anyone manage with 4gb?
I have 5.5gb out of 8gb used, thats mining with a low memory virtual running my wallets. I honestly would say 8gb as a minimum for windows

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.
Some have mentioned that you have to plug in the 6-pin connector to get the system to boot even if you don't really need it, so just be aware when you are getting a PSU that it will need those (Modular probably a requirement). I went with platinum rated PSU for the efficiency of it all, but a newer modular unit was really expensive, so I went this route and haven't had any complaints whatsoever. All six cards running on JPC are about 350W, and When I was mining Groestl is was a very impressive ~265W if I remember correctly.

I can confirm that I originally only had 4gb in my system and it wasn't performing well... I upgraded it to 8gb and a lot of the stability and speed problems were solved. For the extra $30 I would say it is very worth it to make sure and put 8gb in your system.

OC:ed 770 2.9-3MH/s x11 ccminer30 --> ccminer35 doesn't work for me. Don't know why. I'm also mining via laptop same settings as 770 not OC:ed 640M Le = 350KH/s

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

When I'm mining plain groestl or keccak I'm not seeing this, mining JPC it gets a bit more spikey, but at X11, which has 11 different algo's (lol) which each have a different impact on the power usage, it gets the worst. So that may explain those lines. 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.

It seems like one of your cards crashed. You'll have to reboot probably.

I doubt that these two cards are that capable. I was getting close to 7 MHS earlier ~C That's what happens when the card or pool (or combination of the 2) freaks out from too much OC. I eventually had to just completely disable OC while mining JPC, or else this would happen about once a day. And if it happens while you're asleep, you get several hours of mining at half hash rate. Further back in this thread is a way to compile ccminer to exit and reboot when this happens, but that's a bit over my head and I'm just waiting for it to be incorporated into a future release.
