Christian, question: how much system ram do I need for a 4-6 gtx750ti yacoin/protoshares/ultracoin/vertcoin/maxcoin rig?
It seems like in Windows at least, I get lower performance on rigs with 4gb vs an 8gb equipped rig when mining protoshares. Guessing yacoin is even worse?
Thanks in advance.

Guys, I'd like some help with reoccupying this MRC pool - I'm the only one using it now after the stuck block.
http://mrc.easy-mining.net/
I think that the pool owner have to update is wallet...http://mrc.easy-mining.net/
For the moment there are only 3 working pool... and you can't beat blocksolved... (utterly stupid something like 80% of the network)

What model was that bear?
the image he posted earlier showed an EVGA 750Ti FTW ("for the win") edition on a riser - the same model nVidia has sent me for review/testing/whatever
NOTE: In gpu-z my 750Ti reads 30% TDP while mining Yacoin at 3.2 kHash/s. For real? I've got no means to test the power consumption of a single card...
18w mining yac? damn...beats the amd r7 240s at efficiency.

It's a 1x to 16x powered riser, this one:
An yes.. I too and seeing a real delay with BTER deposits as well.

what was your command line when launching cudaminer with the risered card? if you've been using -H 1, try switching to -H 2.
Maybe the x1 bus connection was beginning to limit the hashing speed, so the benefits of any additional overclock were lost.
Christian
I will try that.. It was -d 1 -m 1 -l T5x24 -i 0 -H 1
I replaced it back in the system for now to get some power measurements, I will retry with
System idle 183 watts
Hashing at default clock - 294 watts
Overclocked hashing - 319 watts
Speeds were 1371 GPU /3477 Mem - pictured below

I've solved by bluescreen problems. Turns out that some overclock made the system unstable. I will stick to stock clocks for now.

I remember getting errors like this when i got my 770 last summer and replacing my 660 without resetting evga precision.

Same settings on MSI card do not yield same results :-(
I managed 320kh though :-)

340 kHash/s - for real? This is amazing.
If you find some BIOS mod allowing you to go above 100% TDP this might become even better.
You've been posting great information here. Keep it coming. ;-)

Would this board work with a bunch of 1x to16x risers?
PCI Express 2.0 x16 (2)
PCI Express x1 (4)
http://www.ebay.com/itm/like/171220587477?lpid=82
These usb connected powered risers look good.

I've also received this card from nVidia as a review/test sample. still installing drivers for it....
Are you using a 1x to 16x powered riser? or a 16x to 16x unpowered one?
EDIT: now I am getting bluescreens trying to mine (SYSTEM_SERVICE_EXCEPTION in nvlddkm.sys)
even with all overclocking removed.
Not a good start into the Maxwell era for me.

It does run cool though.. Less that 40c while hashing away, measure at top of heatsink.

Does cudaminer support 6 GPUs at once? Any thoughts on a cheap, yet stable MB with 6 pcie slots? I know of the ASRock BTC model, but it's always sold out at the $69 retail and I don feel like paying a scalper $250 for one.
Up to 8.
I bought these mainboards for my proof of concept rigs:
GA-990FXA-UD5 for AMD (5 x16 slots, but spacing very close, plus one more x1 slot)
and
Asrock Z87 fatal1ty Killer for Intel (it's 3 x16 slots spaced far apart, and four extra x1 slots).
Both mainboards are in the medium price range and target the gaming (SLI/crossfire) market.
I have no experience with risers so far.

Thanks for the feedback!
Now I am thinking a 7x 750TI rig is possible, using the ASRock card you listed.
I also think a 600 watt PS would be enough? I calculate 420 watts (7 * 60 per card) + 100 (MB, CPU, etc), or around 520 watts load. A quality 600 watt such as http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028 should be enough I hope.
The motherboard you mention http://www.newegg.com/Product/Product.aspx?Item=N82E16813157460 is about double of the famed http://www.newegg.com/Product/Product.aspx?Item=N82E16813157471, but what are you going to do? I was trying to keep the ancillary costs to around $200, but now closer to $300.
How much system memory do you think a 7x 750TI rig will need? 4 gig enough or go with 8 gig?
So I am coming up with:
$ 300 - MB, CPU, Memory, PS
$1,120 - 7 x $160 GTX750ti cards
$ 30 - shipping
so around $1,450 for a 7x rig capable of anywhere between 1960 kHash (280*7) to 2100 kHash (300*7) at only 550 watts draw.
Payback will be a bit longer than usual, but I think the key here is the lower overall power draw. A similar hashrate 3 x R9 290x system would draw nearly 820 watts.
Then comes the tweaking. If indeed these can get greater than 300 kHash each and if they can be under-volted for even less power draw, it would swing the balance even more in favor of NVidia.

Finally I see my 1500 yacoin in bter.com now !
Glad to see this.
my friend's 4314 YAC are still in limbo. If bter.com doesn't resolve this, I will have to refund it out of my pocket - isn't that great?
bter.com is dying for me, one failed deposit after another.

Something tells me I wont be able to mine on my GTX690 +GTX670 on all GPUs. I've tried everything. Even -d GTX690#1 and -d GTX690#2. It always crashes driver, or brings my computer to a hault. But, I can run one of the 690 GPUs and the 670 all day... Just not both 690 GPUs. Sucks to have a wasted GPU....
