Sorry, don't want it anymore... I was thinking about it as a PhysX card, but I realized I could get a much older card that would still be perfectly fine for PhysX

I am selling a $25 Best Buy giftcard. I am asking for 1.3 BTC. I am fine with escrow, you just need to find a provider.

I have 6x7970 and with stock fans they are at 60 degrees C. Ambient temp is 65 F. Also, my electricity is 0.12 cents per kW. What are you paying?

3 bumps in one day? seriously?

I wouldn't buy it. That card uses about 80 watts of power and hashes at around 180Mh/s. Lets assume that you pay 0.15 cents per kilowatt hour and it will take you over 10,000 days to break even.

You can use it, but it will be very slow and you will probably actually be losing money because you will be using a lot of electricity compared to how many coins you will be making.

You can send the gift card to someone and they can just send the bitcoins to your wallet.

What are you willing to spend?

I have seen 7950's overclocked to a level that provided around the same FPS in games that a stock 7970 could get. However, mining is a whole different thing. The 7950 has fewer stream processors, making it a slower miner than the 7970 by around 100 Mh/s. Is 100 Mh/s worth $100 though? Probably not.

better buy one, since you have money to buy more grafic cards, you will have another 100$ to buy a psu.
Also i would invest in asics right now, exept if you plan on playing games too
Yeah, when you put it that way it makes more sense. I usually buy a new graphics card every 2 weeks or so, and I figured if I could skip the PSU cost now and add a new card in instead, it would boost my overall hash rate sooner. I am going to stick to GPU's and probably migrate all of them over to litecoin when ASICs drop, so I want to continue upgrading my systems. What PSU are you talking about that only costs 100$? All the ones I was looking at that will be able to support 6 graphics cards cost 200 and up. |

I have been mining for a while, and I have a rig with 4 7970's. I have another computer that I am going to eventually load up with graphics cards as well, specifically for litecoin. Right now, I have one 7970 in that computer and the computer is running on a 600w power supply. My question is, do you think I will have to buy a new power supply before I get a new graphics card? Which graphics cards might be able to run with a 7970 on a 600w power supply?
Upgrading the power supply is inevitable, I just want to know if I can add another card before doing so.

Yeah I would probably go 7950

Uhh all I got was a picture of a flower and the words "My Site". It looks pretty nice though.

I've been mining bitcoins for a while now and I've been lurking on the forums for a while now too. I made an account to start selling stuff, but I found out I could only post on the newbies forum (makes sense). Then I saw a few other people with WTS ads here so I thought it would be fine if I posted one here as well. Of course, from now on I will post my ads in the marketplace.

I have 5 of Gigabyte AMD Radeon HD 7970 OC 3GB GDDR5 DVI-I/HDMI/2x Mini-Displayport PCI-E 3.0 Graphics Card GV-R797OC-3GD 690-700Mhash per card  I just bought one of these to start mining (yes, bad time, I know) how do you get your hash rate up there? I'm at about 600Mhash (give or take) doing nothing outside of the defaults with GUIMiner. I'm a little nervous about changing the overclocking settings because I don't want to fry my board, but if someone can give me any specific guidance it would be helpful. OT: If I don't make all my money back on this card mining, it's okay, I might switch to litecoin mining after ASIC's start shipping if the return looks good, or maybe even do folding@home instead... Edited later on tonite: I tried to launch the AMD/ATI Catalyst utility (win8 64 bit) to poke around and it wouldn't launch. Un-installed it, deleted the folders, reinstalled it, reinstalled the version from the AMD website for win8, (as opposed to the version provided by Gigabyte for Win 7 and Vista) and so on, nothing works. This has been documented a variety of places with a variety of solutions, I tried a bunch of stuff, but if that's the way I have to do it I may have to re-install Windows 8. Not that big a deal since I don't do anything else on the PC, but *this* is why I don't use Windows anymore for personal use... I own the card that you bought. Nobody really uses Catalyst to overclock... I would use MSI Afterburner. Bump your core clocks up by about 10-20MHz, then mine for a few hours. If your computer doesn't crash, you can up the clocks by another 10-20MHz again. When it finally does crash, bring your core clock back to the previous setting it was stable at. On that card, you can't adjust the voltage so you won't be able to get any crazy overclocks. This is okay though, because you tend to use a lot more power when you overvolt. Also, don't worry about cooling for this card. You will be able to monitor your temperatures in afterburner. If you have your fans on the auto setting, your card should stay at around 63 degrees C. Another thing you should do is take the memory clock down to 900MHz. This is the lowest you can go. The reason why you do this is to save electricity. You don't use the memory of the card when you're mining. Just remember to up it back to what it was originally before you play a game or something. |
