Should work fine, as long as you aren't trying to game on it. Mining is low bandwidth, and a couple of my rigs have this: PCI-to-PCIe adapter, which goes to a x1 to x16 riser cable, which connects to a powered x16 to x16 riser, and then the video card. Works fine.

Without overvolting, and with lowering memclock. Yes.
4x5970s
Sempron CPU
optimized BIOS
usb drive running linux
~1050W AC at the wall.

Figure at 90% efficiency that is ~950W DC (which is what PSU is rated on not AC wattage).

Things have gotten rather quiet with news on a launch date for the 7990. AMD announced their Q1 earnings already, all that is mentioned is that they have GPUs from the low end to high end consumers in the 28nm process.

Circulating rumors for the most part suggest AMD has insufficient coolers for a 7990, the 7990 might be skipped and replaced by Tenerife (an island in Atlantic Ocean, not a Southern Island), or the possibility of yield issues.

What we are not hearing about is the possibility of faulty yields.  A number of users in tech site forums mention their 7970 DOA and RMA'd multiple times, their 7970 cannot boot, driver crashes and BSOD resulting in RMA (not known with certainty if driver or hardware, but replacement works properly).

I have experience similar issues with Sapphire 7970, having to send them cross country to CA for the fifth time now; Sapphire would not state what issues they found, or if 7970 issues are common, they (Althon Micro) just ship out another card hoping it functions properly.

The 7990 was predicted to launch on Q1 according to AMD roadmap, a MSI slide reveals TBD in Q2. We are in Q2 now, yield quantity appears to be a problem for many companies, but was the 7990 being labeled as TBD for faulty yield reasons (not enough working yields to make dual GPU boards). nVidia is supposed to be launching something important in the next few weeks, possibly a 690/685/670. One would think something might be going on wrong with AMD.

Too bad 3DFX went defunct.

Think of where we would be if they were still here.

Will you be able to return it.

Should we be gettin public work now because I havent gotten any cept maybe 30 shares the last 2 days? Hows that update comin along pirate?

Yeah I don't want to waste your time but like I said I readed the thread and tried lots of different config.


This is not working either. I tried also commenting mem_speed_2 and lower OC.

You don't get it, it's Bitcoin dragging them down, it must be. Or it would totally be a success by now!

@Coinhunter

Any updated images or screen shots? Just curious if you're surpassed AOL 9.0 yet. Last I remeber you were kicking AOL 6.0's ass.

Wow,
way to get rid off bad PR... change the name, keep the assholes..

I wonder when you will have to rename Microcash again... looking at the price Microcrash would be nice..

OCZ SSD?   Those things are worse than sitting in the electric chair and hoping for a call from the governor.  On the bright side, they know their product is junk, so they never give you any problems with RMA.

On OSX 10.5 the binary works straight out of the box.

if you collect enough condensation points, you get to bonus round.

Wasn't there a post going around of a college kid who suffered brain damage due to all his mining GPUs in his cramped dorm room? Be careful, you should probably just send all those GPUs to me.

No. Help yourself =)

To jddebug, gigavps, sgtspike and others who don't care about 1 fan or 2 fans: I'm glad that's working out for you. It means you'll be happy no matter what shows up in the BFL USPS box.

For others, who cannot hide these things in a basement or closet or datacenter, the difference between 1 or 2 fans is more important. In fact, even the CHOICE of fans is important. There was a post earlier about someone trying to set a Single up in their bedroom. It doesn't matter why: Maybe they have no room elsewhere; maybe that's where their only computer is. The point is that a stock Single, with its dual 43 CFM 2100RPM 27dbA fans, is TOO LOUD for a bedroom in which you are trying to sleep. Perhaps it is even too loud for a living room you use to entertain guests, or a study in which you are trying to ... gasp ... study.

So if a Single arrives with just 1 fan, it's going to be significantly quieter than the 2-fan version (or the dreaded 3-fan version). In my personal case, I've put Singles into a basement office. They are the 2-fan style, and I found them to be disturbingly loud. Much louder than the SLI gaming PC I have in the same room. My solution was to replace the stock fans with quieter ones. Now, even with all other equipment turned off in that room, the Singles can barely be heard. Paradise.

So for me (and perhaps for others), the amount of noise coming from the Singles is very important. Yes, I care that they mine away relentlessly and reliably and that will always be the #1 priority. But I demand they do it with the least amount of disturbance as possible. And I'm happy with the balance I've been able to achieve.

If I had a datacenter next door, an empty garage, or unused basement I wouldn't care what fans they used or how many fans they had or how much noise they made ... because I wouldn't have to deal with that. But when they are in my face, in the same room, and I'm trying to think, they need to be quiet.

So, yes, 1 fan or 2 makes a big difference to me. But I fully understand and respect jjdebug, gigavps, and sgtspike when they say they don't really care.
