So what do you use, if Reaper and CG miner are garbage?

I'm a fan of Ubuntu 12.04 personally, and that's the build I'd probably use, so I'd probably run something similar to whatever you're doing, but with only one card. I'd really prefer to avoid buying another license for Windows.

I run Reaper @ 340 KH/s per core @ 825/1225. 8000 thread concurrency, 5 gpu threads(doesn't seem to make a difference), intensity 17 and I think 32 share threads. I see very few hardware errors(maybe 0.001%) and I get around 10-15% stale shares while running p2pool(about average I believe). Tried up to 950MHz on the core but it decreased hashing throughput. Compared to people reporting upwards to 400 KH/s per 5870, I'm kind of pissed, but I don't know what there is left for me to adjust.

Someone on this forum showed me this and I figured I would share with the community.

Link: http://www.newegg.com/Product/Product.aspx?Item=N82E16814202032

These are 6870's that are really just rebranded 5870's.
So they pull over 400 mh/s-kh/s without the need to overclock.
All for $130 ($120 after the mail-in rebate).

That's over 100 mh/s-kh/s more than a typical 6870, for the same price as a used 6870 on Ebay.

Hurry and get yours before the vultures come, buy them all up, and then try to sell them at a ridiculous mark-up.

You should learn how to keep your mouth shut and maybe youd be able to make some money in this business. If you tell the world than the short run they are doing on them will be gone in minutes. If only a few people figure it out at a time that allows people who know what there doing to make the money. Anyways a little piece of advice.

This is a hobby for me. I am not in this to get rich. I am here to have fun and support the currency, so I much rather help out others looking to get into mining by spreading this deal while it lasts.

thank you for sharing.  even though i am on newegg's site daily i still didn't notice these until you posted.

Anybody got theirs yet? Mine's out for delivery right now, but I won't be home for another 5 hours, to play around with it. Getting antsy!  Grin

I messaged jambaman42 in regards to a listing he made for a 6870:

Hi.  Which 6870 is that?  Is it the version with 1600 shaders?

Yes it is

How quickly can you mine LTC with it?

As it said in the post between 350-420 khash/s per card depending on the settings. I had it running at 414 pretty consistently but then I was fiddling with the settings and it went lower toward the end. This is without OC and temps were pretty near around 70-75 range.

I don't think any of you need to worry...

I don't see anywhere it mentions the number of shaders just people in the reviews. IDK I'm trying to pack as much at the office as possible without blowing the fuse as I don't pay for power there.  I can get more out of 7870XT even though the cost more.  I'm likely to be running 2x7870,2x7950,2x7870xt on a 15A line.

Plenty of other coins to mine besides BTC. I am sitting here nervously watching the LTC exchange rates though..

You should probably hold off for a week or so.  By then, we will have seen if the LTC price has caught up to the difficulty or not.  If it hasn't, it is only gonna get worse.

It's pretty much a no brainer that now is a horrible time to consider building a gpu farm especially if you're looking for short term profits.

Well if you bought 18 of em, you might as well assemble the rigs, mine for a month and then return them.  You would be able to pay for the 20% restocking fee and more

thought about it, but the MOBO's CPU's are not returnable, so that's 450$ alone :S  but nah.. I'll either return them or sell them to forum members.

I will probably be selling 14 of them and keep 4 for myself. Anyone in chicago area wants to buy them PM me. I dont feel like shipping.

I am getting 420khs out the gate.  Will work on tweaking later on.

Finally got them in my system. They show up as 6870s but have the Cypress processors and 1600 shaders. Can't seem to get mine above 320 without oc though.

Mind posting your config that you are getting 420 with?

You should be able to get 420 with 950mhz using all current version software.  I would personally run a little slower depending on heat, I like to run undervolted and see how fast I can go at 1 volt.  It makes less money but the hardware ages a lot slower.
