very nice.

I actually went to so far to not use anything at all besides the mobo-box on a shelf in the garage. not even lego.
my first rig I ended up building a wooden frame, more for the fun of it.

even if mantle could improve hashing, since it is a different technology, the miner programs would have to adapt first....
but, as mentioned, it is a "gaming" thing. it's like asking if DirectX is doing anything for mining and the answer is "no".

Ok, figured it out now. thanks for the offer and sorry the hassle.

Naive(?) question - can I exchange my PPC to LTC or BTC?
If so, how? I don't see where/how to do it. I only see "Buy/sell LTC".

Otherwise, if I sell my PPC - what do I get in return? BTC or USD/EU? They don't seem to trade USD/EU, so - what can I actually do other than to deposit/withdraw?

I figure something like that as well
maybe one can add some additional fans simply. If I look at 7950s with 2 or 3 fans, the casing is pretty open.
water-cooling is a no-brainer, price aside...

I am using 2 (3 once I have PCI raisers) PowerColor HD7950s, I guess it's the reference design. Doesn't make for great cooling, it's always around 80 Celsius, and if I want to push the hashes, the system gets unstable. Aside from moving the whole rig to my garage...

Anyone here knows, has done, tried, to remove the whole cover and leaving only the fan on? Usually the cooling is designed for a chassi with air in/out at specific points. Since the typical rig is just "open", it might help without the cover?
Thoughts?

(water cooling would be "cool", have that on my gaming PC with an old 5850, it never goes over 42 C and is silent... but a bit expensive for a hobby mining rig....)

Have you downloaded the drivers?

http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

use those with the new USB device. should you after that installation not "see" your device (can happen with win7), don't worry.
Fire up cgminer, should work.

If you want to run CG miner for your graphics card as well, make a copy of the CGMiner folder simply.
Use one for GPU, one for USB stick. when us start the USB stick version, use the no-gpu.exe version (for V3.7).

Hope this helps, I am kind of new to all this myself

PS: please don't type in all CAPS, it is pretty exhausting on the eyes.

Well, I find the idea pretty interesting and could see myself buying one/some, or even testing.
Though I wonder if it would be better to focus the developement on Litecoin (scrypt) based miner solely? You know, get more power out of it at same price/electricity?

Ran TAG over night, seems to be ok. I guess this particular one just needs more time to catch up? The first time I posted, it was running several hours, else I probably wouldn't have mentioned it.
Sorry for the inconvenience.

Well, I doubt I will find it, but since it is still alive and kicking, I joined an open pool at least a rerouted my little power to this for the time being.
Never deleted my wallet (why should I have)

Ok, I am confused. The coin is gone, but one can still mine? Besides any - why to do that - I wonder mainly how? Solo-mining? Or are there any open pools yet?
Thanks.

As the title says, anyone used Lego to assemble their rigs? Especially the large Duplo could do the trick, or? Maybe with some glue for safety?

Är det några här som har byggt ngt eget och använd sig av plast/metal lådor/skenor, köpta på Ikea/Jula/K-Rauta/.... ?
Några tips?
Jag har nu delar för att bygga upp ett system med 3 GPU enheter. Försöker tänker på var jag bäst kan leta efter grejor för att montera ihop allt.

Something weird with TAG ? When I switch to TAG I get a few kh/s, maybe if lucky half of my current rate that CGMiner shows.
CGMiner shows me a hash on my single card at ca 250-300 Kh/s, depending on Intensity setting.
DOGE on the other hand is ok, CGMiner shows 100, 200 or 300 Kh/s, then my statistics on the pool show 100, 200 or 300.

I have to add, that I first started with DOGE, then used the web-interface switch to TAG. Maybe something to do with that?

That's odd, but I know I have had something similar with a Fury stick, it doesn't show up, but is still recognized by e.g. Bfgminer.
Try to download USBDview:
http://www.nirsoft.net/utils/usb_devices_view.html

It shows all devices, even "hidden" ones and if active or not, etc. You can easily delete drivers there. Might help to restart the install process.

No, I figured more in comparison to, say, a 280. probably not a 290 or other, yes.
I am not an authority on this, that's why I am asking.

well, there is still the lower power consumption?

7950s are becoming rare, however, there are quite a number of Mac special editions around. I believe they have a physical switch to change between Windows/Mac usage? If they are in "Win" mode, they should be useful even with Linux?
Anyone know/have experience with these?
