MSIA will look like it does it but if you actually hook a power meter up you'll see nothing's really changing.

I should have stated that I set values engine=775 mem=300 volts=.95 fan=40 prior to saving. The only
setting that is actually being saved is my user/pass/pool info. Nothing else shows as being saved when I
open cgminer.conf in notepad. If I close and run cgminer from the command line again (with no switch) it
will remember everything but my fan setting. When I restart the computer, the only info it remembers is
the user/pass/pool info, which makes sense because that's all that's being written to the cgminer.conf file.


My issue is what I'm doing wrong so that I'm only saving the user/pass/pool info and nothing else. I've
also tried editing in the other settings in cgminer.conf in notepad but that seems to have no effect, it just remembers the pool info. Originally, I started it up with a .bat file with the user name and pass if that makes a difference.

Keep in mind that when the first single arrived it's specs were vastly different than advertised (20w vs 85w).

You also have to figure the opportunity cost of the 30k you are setting aside for 6 months? while the difficulty increases.

Is there a step I'm missing to save settings? I use S,W,Enter from the menu to save the configuration as cgminer.conf but it does not appear to save my settings in the cgminer.conf file. It just looks like below. Also when I enter in values and save, they do not take when I start up with cgminer -c cgminer.conf

You'd need another board with usb to host it. Also it would probably have power problems mining just from looking at it.

That's about right for the 7970 if it's stock. Most people are running them about 20% oc'ed, which is why you see the ~650 numbers.

No way a 7990 gets 1350 mh/s. We can dream though.

From reading his post, it's a ASUS P7P55 WS board and he sets it up by putting a single gpu card in the x16 slot and dual gpu cards in the other 3 for 7 total.

It's very possible to get 5MH/W out of a GPU. The reason why people don't do it much is that space is usually limited. In that case, you'd rather have 1 rig than 2 more efficient undervolted rigs. I think the main reason these look attractive (to some) is the space/convenience factor. Otherwise, on a $/mh/s or $/mh/w basis they aren't that compelling.

That wasn't a chargeback. Someone just transferred $1000 from your bank to your paypal acct. You could have just transferred it back once it got into paypal. It doesn't sound like fraud because if it was, it would have instantly gone to another paypal acct other than yours for spending.

I've tried trixx, AB and cgminer and none will drop the voltage on this card. I've had success with 5870s but with the 6990 in cgminer it says that the setting has been taken, but it hasn't.

735mh/s
1x6990 880/600

Maybe should trade it in for 5970s looking at others numbers.

Realistically, when it happens a bunch of people will shut down their rigs b/c of electricity costs, then the difficulty will go down. So although the blocks will be only 25btc it will be easier to get them. Similar to what happened when the $ value of the btc crashed.

You can just pull the shroud off, cut the closed oem sinks so they look like normal ones at the top and install your own fans. Hurts the resale on the cards though.
