Sapphire is pretty hardcore. I also don't feel comfortable lieing and on their webpage they specifically state that RMAs have to be sent through the original seller(ie newegg or whatever) and only the original purchaser is covered.

I would call them and talk it out but the only number I find is for their Hong Kong department.

If you decide to get rid of it I buy broken cards ... PM me if interested.

So, I bought a broken 7970 off of here in the hope to repair it. It is sometimes picked up in RBE (I cannot load bios but the card shows up)... Also Windows detects the card and trys to install default drivers but CCC will not.

***This card cannot be RMA'd due to it being bought from a second party... Plus the block has been off and I've replaced thermal grease... etc***

So upon inspection of the PCB I have found what looks like an area that is less than the size of a dime has most of its capacitors burnt.

These are the small SMD Capacitors that you can see in the picture and the larger ones are labled 2018, 2019, and 2028. The smaller smd Capacitors are not labeled from what I can tell.

So I have tried to contact Sapphire to get the  specs on these capacitors in order to replace them but they will not respond.

I have replaced a SMD capacitor or a 5870 with good results (it works now).

My options are... use some SMDs that I have laying around on spare broken cards: 5870, 6870... etc. I have been told that I can replace the capacitor with higher voltage, ulr, and same or higher capacitance, but not knowing the specs on any of the capacitors I'd have to just desolder a few of the other capacitors of the same size and check them with a meter at school then test some extra capacitors on the spare parts cards I have.


Another problem I have is that I feel comfortable doing this with the larger caps (i'd be using a heat gun or maybe just a small soldering Iron I have)... But I do not know how I would do it with the small caps as they are really tiny. I am going to ask around and see if anyone on campus has a nice soldering/reflow station but it may be a long shot.



Any thoughts or ideas would be greatly appreciated!

Thanks guys!

^Replied and money sent!

+1 for Yunk3r. Quickly shipped. I sent Bitcoins... He sent cards. Would trade again.

pm'ed you^

Is there a reason to only fill up your 1x pci slots... I have three but I would like to still be able to game on this computer. Should I only fill up 1 16x slot and then run the other cards on 1x with risers? new to this and did google but didn't see this addressed

Wouldn't it be cool if this guy^ didn't troll every for sale thread and post his unasked for opinion???   

My 5850s are both on 8x... They hash at the same rate with same settings but one gets 10% more shares completed. I believe this is due to working transitors on the die but not sure. Either way doesn't sound like your problem.

More specs maybe? Whats your affinity on each gpu... etc. Also, are you checking frequencies with gpu-z or msi?

Nope, the two 5850s are in 16x(running at 8x) slots. I could try running one 5850 in a 1x slot... I use this computer to game but don't currently have them in Crossfire cause BF3 doesn't play well.

So... I spoke a little too soon. It didnt boot recognizing the card. I have the card plugged in the second highest pci slot between the two 5850s and it won't even post bios. The monitor doesnt turn on from standby.

I have since upgraded my powersupply to an 800watt corsair. Made a dummy plug for the 5770. and tried the two available pci-e 1x slots to no avail. I'm assuming it is the adapters I'm using at this point or the board itself.

Any suggestions though would be great.

So, the 5850 with the slight fan whine is spoken for. The other 5850 is still available. If someone that bids on it has a good reputation on here I will ship first then accept payment and will be happy to escrow.

Thanks for all the free bumps and trolling!

What about a 20 post count asking me to ship to africa and he'll pay me in paypal... I didnt say i wouldnt use escrow... Thanks for dousching up the thread guys.

I will ship anywhere someone wants via upfront payment of bitcoins.

Lower price!

Have replied to everyone. Thanks guys! Keep em' coming.

The 5770 is spoken for as of right now. 5850s still available.

Check your PMs. Thanks.

Reference lengths on the 5850s. Reference wattage... At the wall each 5850 is pulling 130 while mining. I can get you pics of the pcb if you are serious and interested. PM me for them.

Thanks,
