22  Economy / Marketplace / Cellular company that accepts bitcoin? on: July 20, 2013, 02:21:20 AM
Wondering if anyone knows of any cellular company that accepts bitcoin as a form of payment or otherwise a way to get it using Bitcoin as a payment mechanism

I have a SIM card slot and 3G modem in my laptop ready to be used with a 3G capable card for mobile internet.. and it's be great to have that, but it's only really worth getting for me if I can pay using bitcoins.

Cheers.
23  Economy / Goods / Nikon D70 W/Accessories DSLR & Vivitar 205 MM Lens - PRICE LOWERED on: July 14, 2013, 07:21:27 PM
Virtually pristine Nikon D70 with 80-205mm zoom lens . Great shape. Upgraded to a newer model. Do not need anymore. Camera is suitable for professional work although a standard lens is recommended.

I can also meet for an exchange in the local area if you happen to be in/near North Miami/Fort Lauterdale. All USD prices can be converted to BTC on site with the current exchange rates.

Batteries are in good condition. I only need to recharge each about once a week. Over 2000 shots per charge.

YES, the camera will work with ANY nikon lens, including the common Nikkor 18-55mm VR lens.

Prices are below.

Nikon D70 With All Accessories ( 2 batteries, OEM charger, 4GB Memory Card, Wireless Remote) - $150
Vivitar Manual 80-205mm Telephoto Lens - $30

Photography knowledge not included.

Attached is also a quick photo I have taken with the D70 and the Vivitar Lens.

25  Economy / Computer hardware / [WTS] XFX AMD Radeon 7870 2GB Double-Dissipation on: June 30, 2013, 09:26:13 PM
This is the exact model: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150605

I have two for sale. They were used for mining and ran at a safe 80c on an open-air case. No artifacts and such so they remain usable for gaming. Each achieve 340 KHs mining scrypt on stock clocks (~80C). 410khz overclocked(90C).

I'm in no rush to sell. Asking $230 each. GPU's are also listed on Craigslist. Best offer wins.
26  Other / CPU/GPU Bitcoin mining hardware / What's the best GPU you can get without using external power? on: June 29, 2013, 01:38:17 AM
Hey guys.

What's the best GPU I can find that fits in a single slot? It also has to be able to pull all it's power from the PCI-E slot, and ideally only take up only one slot in the case.

Recommendations are much appreciated.
27  Other / Off-topic / Check out my rig ;) Then guess how much it costed. on: June 28, 2013, 01:44:09 AM
Hey guys. Look at this screenshot.



It has two Intel Xeons 2.5 GHz, each is quad-core. Total 8 cores. (Not visible) 16GB of RAM. No HDD's included though. (But regular SATA drives work)

Now, Guess how much it costed. (The whole rig)

500? Nope. 400? Nope. 300? Nope. 200? NOPE.

$180 with shipping!


It's because it's a rack server. Dell custom built for some company. It's a few years old. (Core 2 Duo  DDR2 era) They bought them by the thousands, Used them a while... then they declare it depreciated and then sell it off. Ebay Listing URL: http://www.ebay.com/itm/271225747786 (Click the relisted URL, They have hundreds...)

Just a cool thing I thought I'd share with you guys, as I'm sure it would interest you. It does get loud though. I intend to modify the cooling system, as well create my own custom case for it, and use it as a desktop. (For fun.)

It also has one PCI-E slot, however it doesn't fit a mining-grade GPU inside the case. Does fit a regular size GPU that doesn't require external power, though.

I can also take detailed close up pictures of all the internals, if anyone is interested in seeing if this would work for their use of it.

I'm loving it. Tongue

Cheers!

28  Economy / Service Discussion / BitSpend Business Indefinitely Closed Because Their Bank Doesn't Like Bitcoins on: June 20, 2013, 01:22:00 AM
BitSpend. A bitcoin-based company which allows you to buy items on regular websites using Bitcoins have closed down indefinitely (apparently) because their bank (chase) has confiscated all of their money, saying that they are a "high risk client" to excuse their actions.

Chase has also said that:

"We will decide within 30 days whether or not to return any or all of your funds"

As of yet we are waiting for something new in this regard.

What are your thoughts? Should BitSpend sue Chase for their massive loss of profits?
29  Other / CPU/GPU Bitcoin mining hardware / How to put your unmodded PCI-E x16 card in your spare 1x slot without a riser. on: June 18, 2013, 12:15:31 AM
Step 1: Take down that wall!

Seriously. I did this, expecting i'd have to jump a pin on my GPU to make it detect. But nope. It works just fine! The GPU autodetects the bandwidth of the slot and runs at 1x speeds.



Works just fine.



No need for these risers anymore!

By the way, if anyone wants to know. The method I used to take it out is by putting a cut-out piece of a PCI connector in the slot to protect the pins, and then using a hot soldering iron to melt off the wall. Took about 5 minutes.

Now, I have two 7870's running on a $30 Pentium 4 board. Tongue Light mining rig base. 380 kh/s stable with mining scrypt.
30  Other / CPU/GPU Bitcoin mining hardware / Passively splitting a single PCI-E 16x slot into 16 PCI-E 1x slots on: June 17, 2013, 05:30:38 PM
Hey guys.

I've been looking around places, and I've found these adapters that seem to split a single PCI-E 16x slot into two PCI-E 8x slots.

They look like this.


As you can see, on the bottom is a standard PCI-E 16x slot, and on the top is two PCI-E 16x slots that are running at 8X speed.

They're fairly expensive. (80 bucks on ebay) But I noticed one VERY IMPORTANT thing that they say about it.



The adapter is PASSIVE! If you look at the photo, there doesn't seem to be much circuitry on the board!

This leads me to believe that the PCI-E spec allows for passive splitting of lanes into at least two slower-speed lanes. The only problem is that normally, this is mechanically impossible. But what if you were to buy a couple of these...


http://www.ebay.com/itm/Powered-PCI-E-16x-16x-Riser-Cable-with-Molex-/111078375273?pt=LH_DefaultDomain_0&hash=item19dcc97f69

And then cut up the cable, and re-wire it to split one slot into two or more lower speed slots?

Once power draw problems are resolved. I think it would be EPIC for running a crapton of mining cards on a single system at very low cost. But only if the PCI-E spec actually allows it.

What do you think? Does anyone know? I haven't seen anything like this done before, so I don't know how well it would work.

I'd get exact percentages, but I don't have a miligram scale and I don't want to risk damaging my iPad mini.  I noticed this as I saw it being disassembled, and so I created this graph from mental/visual estimations. (It's logic board is held down with freaking ADHESIVES!)



I just find it sort of funny. less than 10% of the mass of my iPad mini is actually electronics... what has this world come to? Tongue

Hello.

I need someone who is willing to send me $15 via western union (in the US) today, feel free to include a reasonable fee! I pay you $15 in BTC plus the reasonable fee for facilitating the exchange.

We will have to use an escrow! (No fishy business)

34  Economy / Services / Need someone to buy a UPS shipment for me, and send me the shipping label! on: June 03, 2013, 10:24:22 PM
Hello.

I need somebody who can accept BTC, to buy me a UPS shipment, and send me the shipping label for me to print out. I want to be using UPS Ground and the price that the UPS website estimated for me is 12.06 USD. You tell me what the grand total is before the payment is made, and I'll then send the escrow the BTC.

You must have plenty of trust on the forum, and yes we will have to use an escrow. (Unless if you are a trusted escrower yourself)

(I am also trying to see if bitspend can do this for me, so if they do, I'll just close the thread)

Thanks.

Simple and easy. Tongue

Hi. I have a question.

When I reboot my mining PC, and SSH to it, if I attempt to use OpenCL on it's ATI HD 7950, It doesn't work until I log-in from the GUI. It can't find any OpenCL devices.

Any idea on how to correct this problem?

Ideally I'd like to be able to remove the GUI and run it as a headless server.

Thanks.
37  Economy / Computer hardware / [WTB] Looking for old pentium 1/2 laptop on: May 31, 2013, 10:05:03 PM
Hi.

I used to have a Dell XPI Pentium 1 90MHz and 32MB of ram, but it was stolen from me by some idiot right on the day I got the oh-so-nostalgic Windows 98SE running on it. This was a while ago.

Just wondering if anyone on the forums has a similar old laptop, because I'd like to buy one. Just for old times sake. Wink

Typically anything with Pentium 1 or Pentium 2, or that uses EDO Ram or SD Ram (PC100). HDD isn't necesarry, and viruses or horribly slow OS doesn't matter either. (Duh Tongue)

Edit: I can also offer for trade, some OEM windows serials, or videogame gift codes that came with my Saphire 7950. (Far Cry, Bioshock infinite and Crysis 3) I give first if you're a trusted member.
38  Other / CPU/GPU Bitcoin mining hardware / Standard PCI to PCI-Express Adapters, Anyone got any experience with them? on: May 27, 2013, 06:36:40 PM


A while ago I found these adapters on ebay that convert standard 33/66MHz PCI slots into a PCI-Express slot with 1X speed. Has anyone here gotten any experience with them, and does anyone know if they work on modern GPU's?

These would be epic, as they would allow me to use just any regular old motherboard to run mining GPUs.

Here's the link if anyone wants to see. They are called "PCI to PCI-E PCI-Express 16x Bridge Riser Card Adapters"

http://www.ebay.com/itm/PCI-to-PCI-E-PCI-Express-16x-Bridge-Riser-Card-Adapter-/150736952226?pt=LH_DefaultDomain_0&hash=item23189f5ba2
39  Economy / Computer hardware / [SOLD] HP DV4 Win 7 Ultimate 2.2GHz 4GB RAM Battery Holds Charge! 2 BTC on: May 25, 2013, 02:52:58 AM
Hello.

I am selling my now retired HP DV4 Laptop. Used to be my primary work-laptop. It is fully functioning and ready for immediate use, however it shows signs of moderate wear. Looking to sell for 2 BTC via an escrow!





OS: Windows 7 Ultimate x64, fresh installation, no software included, all updates are installed!
CPU: Intel Core 2 Duo @ 2.2GHZ T6600 800MHz FSB (Mines scrypt at ~14 KHs, for reference on performance)
RAM: 4 GB of DDR3 1066MHz (2x2GB, MAX RAM is 8 GB)
GPU: Intel GMA x4500M HD Integrated Graphics (Suitable for 1080p blu-ray video playback, business/work use, and light game use)
Screen: 1280x800 HD LCD Display
Wifi: Broadcom BG Wi-Fi
HDD: 120GB Toshiba SATA HDD
Battery: Standard 6-cell, Bought it 7 months ago, lasts up to 2.5 hours.

For you techy people, it has two internal PCI-E slots in total, one is free. First is for WiFi, which is installed, while the second is for wireless broadband card. However, I have a modified bios on the computer that allows the use of ANY PCI-E device in the slot. This includes PCI-E Solid-State Drives, secondary WiFi cards, or even external GPU's with the use of an adapter!.

The cosmetic portion of the case has bits of plastic missing in two places. At the indicator LED's as shown in the first photo, and on one on the screw holes of the HDD cover.

Also, instead of a CD drive it has a secondary SATA Hard-Drive bay, which is hot-pluggable. (Secondary HDD NOT included)


I also include the original HP 65-watt Power brick.

For shipping calculation purposes: I am located in 33314, So I will be shipping from there. I have for it prepared a foam-padded box with the following dimensions in inches (width x length x depth) 11.5x16x3.5 and it weighs (rounded up) approx 5 pounds. Shipping costs are not included.

Thanks, and have a good day.
40  Bitcoin / Mining / Cheap mining GPU's suggestions? on: May 21, 2013, 04:53:52 PM
Hi.

I'm wondering if you guys know of any low-cost ATI GPU's that achieve decent hashrates in relation to their cost. They have to be $100 or cheaper.

Just to clarify, I'm not asking for crazy hashrates at no cost; I'm rather asking for an efficient hashrate to cost ratio. If that makes any sense.

I'd use my HD4530, but OpenCL support for it has been dropped in the latest drivers, and no legacy drivers are working properly for me in linux or windows.

Thanks.
