So I take it the h81 btc mobo is reliable after all? I had read some spotty reviews on it, but that isn't saying much as many negative reviews are often the owner fucking up and playing the blame game.

I have had ZERO problems with mine... it has been running 24/7 since the day I put my rig together, and never given me one hiccup.

There are tons of opinions on the power draw through the motherboard and powered risers, and I just said screw it and have plugged in everything and am using powered USB 3.0 risers for each card.

I can't see even worrying about saving $5 on a riser or something is anywhere near worth it.

I personally feel fine with my cards, and I have stuck with the cards that do not have 6-pin connectors on them.

Now if we ever get unlocked TDP/settings that could possibly change, but I haven't seen anything yet suggesting that is near.

Each card is drawing about 38w (just the card), so there is a lot of overhead already to work with if it happens.

If somehow they end up drawing 80-100W/card, I think a lot of setups are going to need some improvement anyhow.

Hope that helps.

Very helpful, thanks.

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.

I guess it is called magma because of the temperature inside the box Grin

ok to everyone looking, the server that is hosting http://cudamining.cc/ is having some trouble due to some memory issues. i have switched it out for another kit to test it, but expect a small amount of down time if i have to order in new kits

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...)

Just be aware that solo-mining can pay off, but it has reached a point where sometimes luck of finding a block isn't going your way.

I have solo-mined JPC for quite a while, and there were days where with 6x 750ti cards I would find just one block. I once had a 48 hour period where I found only two blocks and one of them was orphaned.

It is not for those who will sit and watch the deposits, but you can make more money still it seems than the pools.

I am doing some testing on different pools right now collecting numbers to see possibly how big a difference there is... I am not so sure there is a big gap anymore.

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?

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

). 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!

h81 pro btc
8gb ram(cheapest one)
pentium g3220
sandisk 60gb
5 x risers x1 x16
1 x riser x16 x16
corsair rm650(i don't like cheap psu)
6 x 750ti

Thank you for your speedy response! So I take it the h81 btc mobo is reliable after all? I had read some spotty reviews on it, but that isn't saying much as many negative reviews are often the owner fucking up and playing the blame game.

they should blame their cheap risers, the mobo is good there is a review also with 6x750ti and the owner said, it work great

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 think something is really wrong with X11. I mean each crappy coin get from start several GHash/s right from the start.
(or may-be it isn't a lot actually... if compared to successful coin when only a few coins was launched per week)

something is fishy for sure, secret x11 asic is mining i think, can't be all gpu, the x11coin has 500giga of net hash lol

if I recall correctly, didnt AMD recently get something like a 40% hashrate boost on x11? I mean 500 GH/s is a lot, but lets say out of the usual mining hardware for AMD they'll pull 2.5 MH/s a card on average between the low and high end stuff. that would make that 500gh/s to be 200,000 cards out there in the wild for AMD to be the entirety of that number. Given that scrypt was so popular for so long, would it really be that unrealistic to be GPU alone? Especially if there was some less than advertised multipool or stratum proxy. Dunno, just another theory. It's my understanding that ASICs are not at all easy to make. Wouldn't the most likely scenario be someone with an x11 FPGA set up? I mean either way, they sure as hell will keep it a secret.

was 1 tera, and there are 500giga worth of hash that continues to appear and disappear, must be at very least fpga, but i smell asic

Mmmh I think Innosilicon is already testing their x11 asic right now, and they will start popping to public right after x11 coin hype is over like they did with their A2 chips...

I think it's a combination of several things but one thing for sure: "old" hardware getting reused.
One can easily make an X11 FPGA set-up, by chaining several old BTC FPGA's and reprogramming them. This wouldn't give them a huge speed boost, but they can use it again at a competitive hashrate, so they will.
Many big AMD rigs have been shut down in favor of scrypt ASICs like gridseed. These too are re-purposed, but at a much cooler temp, lower wattage, etc... So many miners who still had their rigs are powering them back on, one by one.

And then there's the newest hype of cudamining

No comment needed.

But I don't think there are any X11 ASIC's out yet that work stable and at a competitive hashrate. It will take some time before you have your own X11 USB miners Tongue

How long does it take to start a big farm ?
(because this is really what I find strange, it starts right away with large hashrate... ok for the last coin I went, starbucks, apparently a chinese pool had the source in advance... at least this is what is rumoured).
Actually I didn't see yet a launch which seemed normal, either dev and co start in advance, either the pool get the wallet in advance. Not a single launch looks clean...)

Ok so im on my phone and dont want to include a load of quotes. My system right now only has 4 cards, due to it being a server board i have 2 pci slots for old devices that i dont have. My current board is well over $200 so i dont expect i am the best to ask about motherboards.

Come christmas time when ive been mining for one year and upgrade everything, and i do mean everything, i will have a better understand to help others. For now i am using the board i have had for about 9 months and had no issues with.

Hmm i wonder if anyone has tried to make a usb splitter to splice a x16 slot to 16 x1 slots. Would be nice Wink
