Not feeling very safe right now. It doesn't seem reliable at all...

Replacing thermal paste helps a bit, too.

That would probably help too, unfortunately that will definitely void the warranty.

Bitcoin is a great idea but could be improved somhow.
The calculation which are made by miner to earn bitcoins are very random and as far as I know very useless, wouldn't it be possible to take this hashing power (at the moment 83.397 Thash/s) and use it to do DNA sequence analysis or something more useful?


I had the same thought. The way bitcoin works today this isn't possible, however a new generation of virtual currency might be able to do something like this. Basically, coins would be allocated to contracts for certain types of calculations. Those calculations would be paid for by xyz company. The calculations would be broken up into pieces and distributed to workers to calculate and shares would be given based on the amount of work done.

The problem I see with this is that instead of the currency now being self-sufficient, it is now reliant on new contracts to generate new coins and the coins are now backed by an actual currency (because xyz company paid for them). Also, generating new coins wouldn't validate the previous ones.

If you click on deposit next to FTC and look down at the bottom where it shows your deposit address do you see an transaction listed as "unconfirmed".

I use give-me-ltc.com and litebonk.com. I don't pool hop, but this at least gives me the option to use another pool if one happens to be down.

GUIminer -scrypt is the way to go. CPU mining isn't really profitable, a pretty common setup is using the 7950's in an open case setup. Just do a search for "7950 rig" and you should find a bunch of helpful stuff.

I wanted to make my first post a helpful one, so here goes!

I found a way to drop the temperature of the MSI 7950's by about 10° C. If you are like me and unable to get a hold of any PCIe risers then this a good way to get multiple cards sitting next to each other without overheating.

I'm using the MSI 990fxa-gd65 with 3 x MSI 7950's with each connected directly to the board without any spacing in between and running them at under 70° C each. This is using GUIMiner with the GPU defaults set to 7950 high usage. I get 570-580 k/h per card with default afterburner settings.


Disclaimer: While doing the following does not void your warranty, doing anything with your card could damage it and I can't be liable for that. Be careful, and don't do things you're not comfortable with.

The way to do this is pretty simple, just remove the mounting bracket on each card.

What you'll need: Small pair of pliers, Phillips screwdriver (both a small and medium preferably), plastic zip-lock bag

Step 1: Remove the pins next to the DVI port. Use the pair of pliers to gently loosen the pins and then remove them the rest of the way by hand.
Step 2: Depending on your model you will either have two or three screws on the front. Using the small Phillips screwdriver remove the two screws at the top and the third screw above the HDMI port if you have one there.
Step 3: Using the medium sized Phillips screwdriver remove one final screw on the inside of the bracket near the top where the cross fire ports are.
Step 4: Slide the bracket off and put the bracket along with the screws in the zip-lock bag.

That's it, now your cards will be able to dissipate a lot more heat! For increased cooling if you are using an open case design (e.g., milk crates) then you can now point your fan at the back side of the cards (opposite the end with the display ports) and the air will be pushed through the heatsink and exhaust out the side with the ports.

If I can figure out how to easily post pictures I will. If you have questions just let me know!
