 Hashing with the cash at 30C has given me a huge increase in MH/J

How much do you think is the gain in MH/J with water cooling?

I have a Radeon 7970 with 56% ASIC quality Shocked It requires higher voltage 1.1V to run at the default clocks.

Any way to get this same effect on Linux without flashing BIOS Huh
Is there a 7970 / 7950 Bios with modded clocks and voltages?

Please try to install MSI Afterburner or GPU-Z and monitor your clock frequency. It's possible that one GPU is running at a lower clock frequency.
2329  Other / CPU/GPU Bitcoin mining hardware / Re: Crossfire setup. One GPU very hot! Restricted airflow... on: May 24, 2012, 06:44:41 AM
Alright so I have the following rig:
PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010
Mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131830
Case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811112300

I replaced a 5830 I had in it with 2x 6870's in crossfire. I use it for gaming and mining. Unfortunately I noticed that the first video card (closest to the cpu) has very little space before the second video card slot. The air intake must be affected because the first card can easily reach 103~ C. I'm not sure what to do. Currently, I have the rig right next to the AC unit and the cold air is keeping temps at 80C & 57C respectively. I can't have the AC blowing 24/7 otherwise I'll get pretty chilled but I'm scared to run both cards with the temps I've seen. Any ideas? I don't think the case is the problem really. There's plenty of airflow in there. I think the fact that the pci express slots are so close to each other is what's wreaking havoc on the one card. The other card has about 1-2 inches of space before the case wall and does just fine cooling itself off.

If you are running Windows (which I presume you are since you have mentioned crossfire), please download MSI Afterburner software. Then a) Lower the memory speed to 750MHz b) Try to lower the voltage to 1.05V and simultaneously bring down clock speed to 600MHz. and check the temps.

You may need to update your ati drivers to support the 7970. I am mining with one 7970 and two 6950 in the same rig.
2331  Alternate cryptocurrencies / Mining (Altcoins) / Re: 7970 undervolting on: May 24, 2012, 06:05:14 AM
Is there any software compiled for Linux that can allow me to under volt reference 7970  cards?

Hello,

electrcity cost

How much are you paying for your electricity?

I agree with you, Newegg Openbox is hit / miss. I prefer ebay for used items since the condition of the items are advertised in advance.

Although I don't have much hope I would be interested to see the results TRL.

::::: Announcement :::::: TradeHill suspending trading and returning client funds.

 Dear Clients,

Effective immediately TradeHill will be shutting down trading / deposits and returning all client funds.
Due to increasing regulation TradeHill can not operate in it's current capacity without proper money transmission licensing. Combined with multiple bank account closures and Paxum's decision to close all Bitcoin business accounts, we have deemed the best course of action is to halt trading and pursue licensing while raising funds.
SEPA transfers for our Euro customers have been enabled.

Everyone at TradeHill has also been working without pay for several months after one of our payment processors removed over $100,000 dollars from our account without notice. We decided to cover this loss for now instead of passing it on to our customers and are taking legal action against the processor. We would also like to make it known that our relationship with Paxum has been great and hope to work with them in the future.

We will be focusing on Bitcoin.com and are preparing to release a new site before the end of the month.
It has been a pleasure working with the Bitcoin community and look forward to continuing our business in the future. More details to come soon.

Sincerely,

Jered Kenna
Chief Executive Officer
