Selling 500k Gmail give me a decent offer and it can be yours, if you dont want to buy all the minimum would be 10k emails. You receiving it in this format, email:password
3  Other / CPU/GPU Bitcoin mining hardware / AMD's 20nm Hawaii [not new, but haven't seen someone post] on: May 15, 2013, 03:27:54 PM
Just posting it up if people interested in knowing the possible upcoming flagship chip (for bitcoin or litecoin use).  There certainly would be optimizations and more power efficiency in architecture logic and with the 20nm fabrication; seems identical in specs to 7990 Malta card?

4096 stream processors
16 compute units
256 TMUs
64 ROPS
4 GB GDDR5
512 bit memory bus (32 bit ram chip interface over 16 chips; Tahiti was 32 over 12 for 384 bit for 3gb?)

5  Other / CPU/GPU Bitcoin mining hardware / Watercooling with indoor faucet/plumbing on: June 11, 2012, 03:08:42 PM
I am considering converting an unused faucet with a G 1/4 thread to run a waterloop in and out of my computer to cool 5 7970's and cpu. Has anyone ever tried such a project or seen it been done?

Perceived benefits:
-cooler water (especially winter) or room temp water
-lower component temperatures -->  lower power consumption, allows good overclocking
-no reservoir, pump, and radiator needed (less tubing)
-much less noise relative to fan and fan+radiator
-I don't pay for water, its in the rent
-Water not continuously circulating in loop, possibly less bacterial growth
-less heat radiated into room

Perceived risks:
-water might leak
-water pressure might change
-water shortages  Angry
-possible condensation of water on tubing/blocks from environment and faucet temps
-Hard or soft water (controllable) - build of gunk in waterloop and clogging
-possible galvanic corrosion? piping uses copper, water blocks are copper

Any other risks outweight the benefits? (This is of course clean water, not toilet water  Cool)
6  Other / CPU/GPU Bitcoin mining hardware / Radeon HD 8000? (little help translating Turkish pls?) on: June 08, 2012, 07:27:32 AM
Stumbled upon this, Google Chrome produces a weird translation:

http://www.donanimhaber.com/ekran-karti/haberleri/AMD-Radeon-HD-8000-serisine-iliskin-ilk-isaretler.htm

Radeon 8970 & 8950 = codenamed Venus XTX & XT
Radeon 8800 = Venus LE & Pro
Radeon 8700 = Oland
Radeon 8300-8600 = Mars

Most of these are planets in outer space, except Öland is an island, lol, not exactly "Sea Islands."

Edit:

Did a Google news search for "Radeon 7990" limiting results published in the last 24 hours.

This came up: (Appears to be legit? - multiple search results have this)

8  Other / CPU/GPU Bitcoin mining hardware / Best way to measure power consumption of graphics card? on: April 25, 2012, 06:56:42 PM
Many user compare measurements at the wall via a kill-a-watt, then subtract further to isolate graphics card wattage. How accurate are the sensor readings in GPU-Z and HWiNFO64? Is using a multimeter any better (being careful with probes, not to short anything)?
9  Other / CPU/GPU Bitcoin mining hardware / Anyone ever shop at HomeTH? Radeon 7970 for $232.16 + shipping (~$40) on: April 17, 2012, 06:11:08 AM
Type in Radeon 7970 in Google, select the Shopping tab, sort by lowest price, go to second/third page.

Anyone shop here? I am tempted...

This is eye catching: (Would there not be a PCI-E controller?)

11  Other / CPU/GPU Bitcoin mining hardware / Soldering vacant power circuits on gpu (6850/6870)? on: March 30, 2012, 10:33:43 PM
I have a Sapphire 6850 lying around, and noticed solder terminals to attach a secondary 6 pin PCIE power cable. It seems the solder points are connected to to an incomplete power circuit. Has anyone reconstructed such a circuit on a graphics card?  A 6850 flashed to a 6870 remains a 6850 functionally; would an additional power circuit alter the functionality or permit performance as a Sapphire Toxic (OC) card?

12  Other / CPU/GPU Bitcoin mining hardware / Possible line-up for Kepler cards if anyone interested on: March 27, 2012, 11:02:49 PM
Someone tested Kepler and posted numbers in some topics already: ~105 MH/s. I stumbled upon this webpage, provides possibly the whole line of Kepler cards yet to be released, apparently there will be a GTX 685 preceding the GTX 690.

From the Newbie section: https://bitcointalk.org/index.php?topic=74215.0

Sorry, I can't post in the main 680 thread because I lurk.

Hey, just got back from the store with a 680. Here's a quick benchmark for people, and it's not looking good so far.

This is a stock EVGA gtx680, with latest drivers (301.10) and ufasoft 0.28, run with -t 0, under win7 x64.

Getting around 105Mh/s.

 Cry

Thankfully I didn't buy it for mining.
13  Other / CPU/GPU Bitcoin mining hardware / Kepler vs Radeon [GCN] Architecture, any 680 GTX reviews on mining...? on: March 22, 2012, 07:44:20 PM
There are numerous topics in this forum already posted regarding the upcoming 680 GTX. So far I have not seen any reviews investigating bitcoin mining on this new gpu, nVidia's website does not mention its application for mining, it is mentioned merely as a gaming card.  Has anyone found any solid numbers? The 680 triples in number of streams over the 580, despite architectural differences, what does this translate to versus the 7970?

Perhaps the closest benchmark posted on the net so far concerning GPGPU performance is on the Bright Side of News: this article compares single and double precision power between the 680 and 7970, and the 590 vs 680 in CUDA (590 wins in double precision). The 7970 significantly "smokes" the 680 in double precision in cryptography, yet the 680 "smokes" back the 7970 in single precision. Another article on this website will be published analyzing the 680's architecture more in depth yet.
