I have three GPU's for sale.

Here are the details:

Sapphire Radeon HD 5830:  This card was used flawlessly for about a month, and now it has been sitting in a corner for a few months.  In that time, the fan went bad (anyone have a clue how this happens?!)  Now the fan barely spins.  Anyway, the GPU is still fine, but it will need a fan repair before using it for anything more than running windows.  I will sell it for 10 BTC including shipping, OBO.

Sapphire Radeon HD 6950:  This card hashes like a maniac, but unfortunately one of the two fans only runs about 15%.  Since it has 2 fans, it still stays relatively cool, but I am not comfortable leaving it running.  I imagine someone with more knowhow than me can fix this issue.  This card was bought new in August.  I will sell it for 30 BTC including shipping, OBO.

MSI Radeon 5770:  This card is in flawless condition, works perfectly with no issues.  Dual fans is nice.  Used for 4 months at factory speeds to hash.  I will sell it for 10 BTC including shipping.

Ask any questions you want!

That 5770 is looking good for 9BTC

i'd be interested in that 5770 if Celcoid isn't going to buy.

Celcoid offered 9 BTC.....if you offer 10 it is yours! 

Is shipping to the EU a possibility?

Unfortunately no....sorry!

The 5770 has been sold to user luo demin, for 10 BTC.

Thanks for the ultra fast payment!  Will ship today!

No problem yochdog I can't wait to get it !

Hey all, I still have the 5830 and the 6950 for sale.....Make me some offers!  I know someone out there wants to pick up a bargain!

I'd do 9 on the 5830.

SOLD!  Send the 9 coins to 18wLgRN7ZQZkquPfDb2y2p2hffPvX2yVmM

thanks!  PM me your shipping address. 

9 bitcoin? Hot damn, did btc just spike to $10 or did I miss out on a good deal!

I sent you a message offering 9 a few days ago on that 5830......

read the OP....the fan needs replacing..... :-\

If its a sapphire (i thought it was) use litium grease on the oil well under the sticker on the fan.

The buyer will have to give it a go.....It is boxed up for shipping. 

Sent the BTC and a PM with shipping info.

average going price of used 5830's is ~$75 in full working order.. So, $63 with bad fan is what I'd think is a 'normal' deal. Not a bad one at all, but certainly not insane either. ;p

I'm only pissed that the one day I don't check goods 20 times, this slipped by me. =)

cheers

Bump one more time.....only the 6950 is left for sale.  Works great, just need to watch on of the fans.

Make me an offer! 

No offers?  Anyone?  anyone???

10btc

22 and its yours.

15btc

Let me think on it.  I can always drop it in an open mining rig and run it on my own...

You said a bit ago that you didn't trust the fan to run the card.

One fan is going bad....the other is perfect.  I just didnt want it running in a closed case where it could overheat and I could not monitor it.  In an open rig it would do just fine.

I will pay 17 BTC for the 6950 although I only have 14 right now (shouldn't have bought BF3 for a friend last night!). I'll be mining at 8-900 M/Hash so it wouldn't take long to pay the additional 3.

Throw in 2 BTC for shipping, and it is yours!

I can wait the couple days while you mine.....

If you want the deal, you can send the 14 BTC now to hold it. 

You've got a deal- 19 Total Shipped. Without the card I'll be at 550-600 M/hash so it may take a bit longer to get them to you- i get about .3 BTC a day if that's okay. you'll get the first ones I mine.

Edit: i forgot that I sold some giftcards so I'll send you 17* up front, then 2 more once I get them mined

Sounds good to me.....send the 16 to 18wLgRN7ZQZkquPfDb2y2p2hffPvX2yVmM


I will ship it Monday.  I trust you on the remaining balance!

Good doing business with you. 

Just sent coins (17 actually) and a PM with shipping info. A pleasure doing business

I forgot to ask but is this the 1Gb or 2GB version? I'm not going to try to back out of the deal or anything, just curious

It is the 2GB.  SCORE!!

Great! Did you get the PM/payment?

yes, thank you.  will be shipped Monday if I can find an open UPS store.  no later than Tuesday though. 

The card arrived as promised, thanks yochdog for the fast shipping a great packaging oh the that 5770 hashes pretty dam well !

Same. Card arrived, packaged nicely, exactly as described.

Just curious but what hashes are you getting from that HD5770? stock and overclocked?

Overclocked and overvolted 1050mhz core at 1.25 volts and stays pretty cool it produces around 220-240Mhash 24/7 stable


Edit( not every 5770 is gonna be able to clock this high )

That card is a beast.....never missed a beat and runs cool. 

Wow that card is really good for a budget.I wish I could find 2 used HD5770s in UK last summer instead of buying 1 HD6950 (it was the unlocked shaders that tempted me as it gave me more value for money but UK didn't sell HD5770s last year which is a shame)

My HD6950 only gives me 400MHashs and that HD5770 is like more than half the performace of my card.Talk about a good cheap GPU (runs cool,overclocks,overvolts and performs well)

The HD6770s (the only equivalent I can find in UK now) don't perform as well as HD5770s. I wonder how much energy these HD5770s/HD6770s used at those speeds? As my PSU is quite old and can't support multiple GPUs easily or 1 huge GPU (even thats out of the question now due to weak amps on 12V rail and PSu was bought in 2007,released in 2005 as price came down)

I just hope that the HD7770s perform as well or better than the HD5770s (as they will be more accessible for me as I'm in UK)

well for reference my killawatt tell me I am idling at 190 watts with a 6950/5770 then with the 5770 at load I am at 290 so somewhere around 100 watts or so

Thanks for that luo demin.Very useful for me indeed.This shows that I could get up to 480MHashs (in theory with the best overclock) while using 200W total with 2 HD5770s as opposed to 400MHashs at 220W with my HD 6950 so there are cost and energy savings to be had (though not by much).My PC idles at 85W (at best typically this is 94W) with HD6950,PC then uses 300W when HD6950 is under full load (Overclocked heavily and fans at 54% plus unlocked shaders.)

All my readings are from the wall with an 80% efficient PSU (before the 80% + standard came into place.The PSU is Enermax Liberty 620W-old one,not the eco model).

The TDP of a 5770 is 108 watts so its gonna be near the same wattage with 2x5770. what are the specs on that 6950 ? unlocked ? mine gets too hot above 950 core so basically im stuck at 350mhash stock shaders

Setings on my HD6950 are:
Unlock shader mod (from 1408 stock shaders to 1536 unlocked shaders)
core clock:895MHZ
mem clock:320MHZ
Fans:54%
Volt:stock at 1.1V (1100mV)
Temps:77oC (up to 80oC on a really hot day so far)
On mine,its best to keep temps under 85oC otherwise it crashes with unlocked shaders (doesn't crash at this temp with stock shaders)
~400MHash/s
Power use (from wall):210W (220W+ when overclocked and overvolted above these settings.)

I hope this anwsers your question :-)

Thanks that was helpful those extra shaders really do help I got some bios work to do on that 6950 !

I'm glad that tip about the unlocked shaders helped you :-)

Without unlocked shaders the GPU would only do 370MHash/s at those clock speeds.Unlock the shaders and I reach 400MHash/s (sometimes even more than that on good days)

Have either of you tested for stability with lowering the voltage? If you can run stable with lower voltage it will bring donw those temps a bit and/or allow for a bit higher gpu clock.


Stable at 1050 on the 5770 is very impressive btw, Luo!

It will go higher 1100 on 1.3 volts but thats pushing it a little to hard for my taste and honestly I just got the 6950 not too long ago and I hope to put it under water some time soon. the temps are just too high on air for 24/7 oc'ed.

Just received the 6950 and it's exactly as advertised, great trade! Surprisingly, it runs about on par with my 5870 temp wise even though one of the fans half works at 73 degrees while mining without my huge house fan on it. Will be interested to see what the temps are like once i get a replacement fan!

yochdog is a great trader, will definitely do business again if opportunity arises!

I've got about 1.3 of the 2 coins that I owe you. Will let you know when I send them- should be soon :)

Sounds good.....Im glad it is working out for you.....I knew someone would find a good use for it and love it.  It is a great card. 

just sent the other two coins that I owe for the 6950 to 18wLgRN7ZQZkquPfDb2y2p2hffPvX2yVmM
sent it from 1FMH9e1HsiUz9HTGaw56FFvc4eVew5qWKt

thanks!
